this question is >2.5 years old

barneyman 29-Jun-17 0:57am View

ok

barneyman 22-Jun-17 23:20pm View

yeah - i saw that too - but %n is doc'd as returning 'chars printf'd so far' - TIL !

barneyman 22-Jun-17 20:09pm View

i quoted the EXACT general case

DO NOT concat strings, use arguments

barneyman 21-Jun-17 19:05pm View

DO NOT concat strings, use arguments ... a quick google turned up this http://php.net/manual/en/pdo.prepare.php

barneyman 7-May-17 23:58pm View

what have you tried?

(and TeamSales is a completely redundant column, it can be calc'd)

barneyman 7-May-17 19:59pm View

Griff is suggesting (correctly IMO) you use another referential table, so to get to the images you'd do something like this (using his schema)

SELECT Imagedata FROM IMAGES WHERE ProductId=@ID where @ID is got form the Products table

if you want another column, person, then you need another Person table and personid

you need to research SQL Normalisation - and for the love of cheese, use GUIDs as IDs and UTC as your timezone

barneyman 8-Feb-17 19:21pm View

admin elevation required?

barneyman 19-Jan-17 20:56pm View

what exception do you get?

barneyman 18-Jan-17 18:17pm View

that URL and the explanation does not preclude you from using C++

it talks about creating it and the messages you have to intercept

barneyman 9-Jan-17 21:03pm View

you could do it with a trigger on the insert

Why are you trying to do it this way, it seems (on the face of it) a bit confusing - What happens if a price is added, or removed, later?

Adding strings to rowids is a bad idea too ... that should be done by the presentation layer - IMHO

barneyman 22-Sep-16 21:31pm View

the first linked example is pretty much step by step ...

how is it failing for you?

barneyman 20-Sep-16 20:14pm View

QBW has an ODBC driver http://support.flexquarters.com/esupport/index.php?/Knowledgebase/Article/View/2347/49/how-do-i-build-a-connection-string-with-all-the-available-qodbc-parameters--connection-string-with-qodbc-parameters

so you could just try importing direct into SQL

barneyman 13-Sep-16 22:40pm View

because that's the standard way of expressing hex and octal, in programming

barneyman 4-Aug-16 18:23pm View

you may need a more pro-active approach - something like VLD https://vld.codeplex.com/ may be useful

You may not have a leak, you may simply be fragmenting the heap?

i generally round the allocation size up to a the nearest para when a have a *lot* of heap hits

barneyman 2-Aug-16 19:26pm View

the matrices are very important to understand, there are a few tutorials around

http://www.toymaker.info/Games/html/matrices.html

barneyman 2-Aug-16 2:21am View

does the DX device paint anything, i.e. the background? is your render called?

Try just using a colour triangle rather than a textured one to start with

if it's painting, but you're not seeing anything, odds are your view matrix is broken

barneyman 31-Jul-16 19:08pm View

what exactly fails? the build, or it executes and nothing happens?

please be explicit

barneyman 27-Jul-16 1:06am View

CMyClass::StdDispatchImpl<cmyclass>::CreateInstance ?

barneyman 21-Jul-16 2:52am View

you need some form of read/write locking on that data buffer - currently it has the potential to change while printf is traversing it

barneyman 20-Jul-16 5:52am View

you're in the middle of an interrupt service routine - you have to get out as quickly as possible,and make no blocking calls

push the data into a pre-allocated buffer, and let another, normal, thread do something with it

barneyman 20-Jul-16 0:47am View

32767 columns?

sounds like a singed int max limit

barneyman 13-Jul-16 19:08pm View

are you in a CWnd derived class when you call this?

Sounds like you're getting ::GetDC, which returns an HDC

barneyman 5-Jul-16 19:49pm View

why on earth are you storing dates as strings?

ok - so you're going to have to CONVERT each row datestring into a DATE and the min/max datestrings also into DATEs

barneyman 11-Jun-16 20:20pm View

you've asked this question before, and been given the answer

http://www.codeproject.com/Questions/1105390/Different-value-pixel-in-C-and-Python-language

in python the image is being parsed/interpreted by the image library, in C you're reading the raw bytes

barneyman 10-Jun-16 0:20am View

there's only one semicolon in that procedure!

and it shouldn't be there

barneyman 9-Jun-16 7:46am View

so, what's the problem? obviously you have to determine the threshold for B vs W

barneyman 7-Jun-16 19:43pm View

you don't have an exit condition ... it'll find 3 fives, then it won't find any - so it'll return .end() - which you then try to increment

barneyman 6-Jun-16 19:56pm View

depends on the format of the image

barneyman 5-Jun-16 20:55pm View

because you're still messing with the local decl (of m_coordslist inside OnInit..) and not the member

barneyman 5-Jun-16 19:54pm View

i don't see anywhere where you're creating, or attaching to, that list control (which is LOCAL to the OnInit... it's obscuring the global)

barneyman 2-Jun-16 18:15pm View

you're guessing until you debug it - windbg or vs remote debugging - the latter is easier, the former less invasive

barneyman 26-May-16 22:00pm View

if regsvr32 doesn't give any errors (and you were UAC elevated) then the registration worked ...

it sounds like the proxy isn't proxying ... define 'doesn't work' please

is this a proxy/stub or just a proxy - is the com object it's proxying for registered .. if you watch the regsvr32 process with procmon.exe is it making the right registry entries

barneyman 18-May-16 20:02pm View

you might want to look at RARP

barneyman 10-May-16 20:27pm View

as pwasser says, it's probably something broken in the header, or one of it's children

that said, i DO recall an incident where the preprocessor barfed because there wasn't a trailing \n\r after the last directive (on the last line) in a file

barneyman 2-May-16 0:15am View

from memory (this is 1999!), irDA is implemented in Windows using the winsock libraries

barneyman 15-Mar-16 19:29pm View

two observations

1. you don't do any bounds checking (ie when count==SIZE)
2. how does displayCoins know how many coins were input in getCoins, magic?

barneyman 6-Mar-16 16:04pm View

also worth pointing out that some optimisers will consider the inline keyword a suggestion, and may decide not to honour it

barneyman 27-Jan-16 21:19pm View

you're trying to populate the DA with the entire rowset ...

try using Fill paging

barneyman 18-Jan-16 19:33pm View

no, no you don't - then you're messing with a container AND its contents, every time you add/del from it .... as SA says, use a std::string, or CString

barneyman 7-Jan-16 15:56pm View

Edit/Find ?

i'd look for the string .. it'll either be in the DIALOG rc definition or it'll be a string in the stringtable (in which case then look for that define elsewhere) or it'll be inline in the code

barneyman 10-Dec-15 20:25pm View

see my other comment down the thread ... google

i could give you a salmon, but you learning to fish is best

barneyman 10-Dec-15 19:58pm View

no - 426 was being obtuse :)

the function 'Increment' is simple - google 'c++ how to call a function' will help you

Increment2 is more complex because of the pointer (*) qualifier - you need to get the addressof count, which is where the ampersand comes in .. again google 'c++ pass pointer to function'

barneyman 10-Dec-15 19:48pm View

the word 'loop' wasn't mentioned in your original question

you just call them ? they're functions .... it's a procedural language ...

Perhaps you've not outlined your *actual* requirement fully?

barneyman 9-Dec-15 21:06pm View

true

barneyman 9-Dec-15 20:31pm View

also, pass the array by reference max(float &vec[]) - code will be faster, especially for large arrays

barneyman 9-Dec-15 20:24pm View

only if you want it to work :)

barneyman 9-Dec-15 20:11pm View

what value does max start with?

barneyman 5-Nov-15 21:13pm View

good catch!

barneyman 5-Nov-15 19:21pm View

cursory examination looks ok - have you tried debugging it?

barneyman 28-Oct-15 22:45pm View

use the TCHAR and _T("" )defines - that will be char or wchar depending on your compile - the Regex and Http libs have both impls

barneyman 27-Oct-15 18:43pm View

as i said, error code 1638 is for a different situation - additionally, 1638 is returned WELL before any copies start - installUIsequence

barneyman 27-Oct-15 18:34pm View

arg0 is automatically supplied by the startup code - you don't need to specify it

barneyman 26-Oct-15 17:26pm View

argv[4] would be the *path* to the input file (ie /usr/binaryoffset/wibble.bmp), similarly argv[5] is the output *path*

barneyman 19-Oct-15 22:37pm View

i use the 2nd method (in C++/OLDEB) and always found it returned the same result set as the datalinks dialog (UDL)

i used google with "geotiff examples"

barneyman 14-Oct-15 1:00am View

how does using a public key make it vulnerable, and why does using the private key resolve this? it's asymmetric - you're robbing peter to pay paul!

barneyman 12-Oct-15 17:50pm View

no idea - tho' NSIS doesn't install using the MSI engine, so maybe win10 is locking it out - UAC possibly?

And DO NOT change the browser without user interaction - that get's you immediately uninstalled in my world

barneyman 1-Oct-15 0:32am View

please edit/rephrase the question - your first version is not exactly clear

barneyman 30-Sep-15 20:32pm View

why are you using directx to do this?

do you simply want to screengrab an arbitrary HWND (including desktop)?

barneyman 27-Sep-15 7:28am View

Macie is right - we need code ...

writexml will honour the structure in the order you add nodes to it

barneyman 24-Sep-15 19:07pm View

couple of observations/questions here ..

1. your xml (both examples) as quoted, are broken - they're not closed - have you simply pasted them incorrectly?
2. are you saying the XSD re-orders it, or the writexml method?

barneyman 23-Sep-15 7:32am View

neither make sense and will do what's posited

the second won't even compile

barneyman 22-Sep-15 6:09am View

my money is on you calling the first method/member on a null pointer to a class

barneyman 21-Sep-15 6:09am View

barneyman 19-Sep-15 19:46pm View

have you tried catching the exception and using the what() method?

barneyman 10-Sep-15 8:31am View

have a look at cursors

barneyman 10-Sep-15 8:27am View

where are you stuck? what code have you written?

barneyman 7-Sep-15 18:27pm View

it would appear your DB is broken then ... advice under that condition is to restore from a recent backup, and apply the log files forward

and check your disks, they caused the problem

barneyman 3-Sep-15 21:13pm View

presumably because the backup job is locking pages to, er, backup?

barneyman 3-Sep-15 6:33am View

i'd reverse the input string ... what are your thoughts?

barneyman 2-Sep-15 2:41am View

good eyes!

barneyman 31-Aug-15 8:13am View

good luck

i'm hoping Adobe publish their Photoshop code one day

barneyman 25-Aug-15 18:46pm View

what's the code, what call fails, what's the error, (GetLastError()), where are you writing it to etc, etc

"my washing machine isn't working" - can you diagnose and fix it from that one statement? ;)

barneyman 24-Aug-15 15:50pm View

please delete this solution, and respond to Richard's ...

i'd suggest he'll say "same error, same problem - that's not how you cast in VB"

barneyman 20-Aug-15 4:42am View

for the love of cheese, use ATL to create a COM object - trying to use flat C to provide an OOP solution is an exercise in frustration

barneyman 18-Aug-15 23:31pm View

no - your original problem is that you're trying to write to the sample.xml file, in your install directory - which you don't have write access to

So, create the sample.xml file somewhere you DO have write access to, my example was the temp folder, but appdata is equally viable

barneyman 18-Aug-15 18:58pm View

unlikely - if it's in the typelib, it's in the api - it's a property tho, so it would be get_length

anyway, there are a number of other ways of iterating thru the swatches, have you tried them?

barneyman 18-Aug-15 1:47am View

have you tried 'length' ?

barneyman 13-Aug-15 20:22pm View

elevation, i'd guess

barneyman 9-Aug-15 7:52am View

have you confirmed the name is correct?

barneyman 9-Aug-15 6:42am View

it's not mandatory to register progid's, only clsid's - i don't know if vbs can instantiate using clsids, maybe look at the clsid moniker "clsid:xxxxxxxxx" or register your own progid -> clsid mapping

barneyman 9-Aug-15 6:36am View

so, have you done what it suggested?

barneyman 6-Aug-15 18:31pm View

intellisense will whinge until the idl is first compiled, because none of the headers have been created by midl

what *build* errors did you get?

i generally ignore intellisense errors

barneyman 5-Aug-15 7:18am View

create an atl dll project, then add an atl simple object - add your method to the idl, and impl to the cpp/h - done

barneyman 4-Aug-15 1:46am View

i'm not sure i understand ... if you want to know what that code's doing, single step it and find out (it looks to be building 2 digit sets from all the permutations of the array 0..9)

if you want to know how a std::set works, look at the header, though knowing the specifics wouldn't be too useful IMHO

barneyman 4-Aug-15 0:53am View

it's an insert OF a vector into a set, not ON a vector

sql server profiler

barneyman 2-Aug-15 20:29pm View

does pActiveDialog get changed by another thread, or message handler?

i'd put a mutex round it if that's the case

barneyman 2-Aug-15 18:06pm View

it'll have to be a deferred action, to run during the install - MSI's run 'twice', once to generate the scripts, then the execute the scripts - it's very difficult to get user data to a deferred action that's not been worked out in the scripts (the latter includes file#, and properties, including directories)

barneyman 26-Jul-15 9:59am View

not really helpful, i've had the same issues :) SetRate never worked for me either - you might have to look at using pull via IAsyncReader

barneyman 25-Jul-15 8:09am View

just guessing, but if you can't google for 'javascript xml', maybe coding isn't for you?

barneyman 23-Jul-15 7:05am View

barneyman 19-Jul-15 23:14pm View

can't you just use multiple FTDI usb boards?

barneyman 9-Jul-15 5:46am View

it's challenging because your explanation is not entirely clear

why not import to Excel directly from SQL, or export from SQL directly to Excel - both are easy google searches

barneyman 8-Jul-15 6:32am View

dont forget to handle paste, and selection edits

barneyman 5-Jul-15 23:25pm View

sounds like you need to add a 'balance' column to the sql query you're populating the gridview with

barneyman 2-Jul-15 20:15pm View

those two implementations fundamentally do the same thing, you'd need to detach the t object for it to run in parallel

as regards the 'appears to hang' - feel free to break into it with the debugger and find out what it's doing

barneyman 29-Jun-15 20:12pm View

there's an installer creation tool, called WiX, it's pretty powerful, and can run scripts for you ( https://gist.github.com/rrreese/4104368 )

caveat: i don't use WiX, i use something i wrote, which is almost identical ... simultaneous invention :)

barneyman 28-Jun-15 21:30pm View

as scripts that create the db, tables, sps, and logins etc

barneyman 25-Jun-15 1:33am View

right - so does that file exist on the E drive, and does the user you're running the script as have access to that path?

barneyman 25-Jun-15 0:57am View

<sigh> what error do you get?

barneyman 23-Jun-15 19:35pm View

because it does!

google for 'circular dependency' and you'll find some solutions

barneyman 23-Jun-15 19:12pm View

well spotted!

the OP's putc will be failing (because ftest is opened for R)

barneyman 23-Jun-15 3:13am View

what model are you initialing COM with in your console app?

barneyman 22-Jun-15 20:14pm View

randomly :) be aware that the IStream created by the shell and create...hglobal cannot be QI'd for ISequentialStream, which may or may not be a problem for you

barneyman 22-Jun-15 2:12am View

all the clues are there

barneyman 9-Jun-15 1:10am View

the hanoi tower problem is the standard example for recursive algorithms - either single-step it thru the debugger, or walk it manually, noting diskSize, source, dest, and spare on every recursion - shouldn't take long

barneyman 4-Jun-15 8:02am View

lol - that wasn't your original question - i answered your first question (setting background colour)

barneyman 2-Jun-15 2:38am View

there's nothing special about the code S[x[0]] - it's original value is 0xCCCCCCCC (which is stack 'undefined' value in debug) - i don't know where you're getting 0x32FBC0 from

S is initialised to -1 in preSo, and then there's some XORing going on ...

Debug it ...

barneyman 2-Jun-15 2:03am View

you're correct - it means the S[97] (where 97 is gleaned from x[0])

barneyman 1-Jun-15 19:50pm View

the registration of the COM element would be the first thing to investigate ... regsvr32 should be done as a post build step

barneyman 27-May-15 22:33pm View

there is no representation for the ascii null character, so even if you could get the MsgBox or SetWinText to take a pascal string it wouldn't know how to display it

i'd advise having some function that takes the array, and the size, and returns a string with the null converted to some other character

barneyman 26-May-15 7:08am View

it doesn't have a format - it's just time ... what makes it UTC is that it has no timezone (technically, it has TZ0), or DST applied .. it can be expressed (according to ISO8601) as a time string with Z at the end

barneyman 26-May-15 7:01am View

i'd guess so - the docs would suggest the 3rd overload would do exactly what you want

https://msdn.microsoft.com/en-us/library/windows/desktop/dd371803(v=vs.85).aspx

i've never used d2d, my experience is with d3d, however, a bitmap is a bitmap is a bitmap :)

barneyman 26-May-15 1:21am View

so your scanline (Width) is 256 with 3bytes per pixel - 3 * 256

there MAY be padding in there too - divide the filesize by 256, don't be surprised if it's not 768

i assume that ctor for CD2DBitmap creates a bitmap that's the same size/format as the render target? if that's 256*256*24 it should be fine, otherwise you're going to have to create an HBITMAP from the raw data and use the CRenderTarget ctor that uses HBITMAP - MFC's CBitmap is ok for that

barneyman 26-May-15 1:01am View

the stride will be determined by the format of your RGB - if its RGB8 it'll be 3x your scanline, if it's RGBA8 it'll be 4x etc

barneyman 25-May-15 22:25pm View

lol - i can - you couldn't afford my hourly rate

barneyman 25-May-15 22:24pm View

i get that ... we all were once, but me fixing it *for* you doesn't make you any more senior :)

InsertBST is broken ... the contents of your first if(T==NULL) clause is the root cause of your problem (i'm guessing, you've not actually expressed what the problem is) - format it so it's legible, and read it ... it's 10 lines when formatted correctly - the problem should jump out at you

when you've fixed that, have a look at #2 i made

barneyman 25-May-15 22:04pm View

i thought i just did?

barneyman 22-May-15 1:02am View

it's better than my Vietnamese ;)

The link you point to is *specifically* about using the SQL profiler, which is a performance and monitoring tool for SQL, that API provides no ability to access SQL data securely - i'm unsure what you're trying to achieve ..

barneyman 22-May-15 0:29am View

that looks quite easy - you have a couple of inner joins on a criteria select

where are you stuck?

barneyman 21-May-15 23:46pm View

you're assuming you get the entire frame in your UDP receive .. you make no attempts to validate the size of the buffer you got, and if it's of the expected size - then you hand that buffer off to Decode... which also assumes it's the correct size ... and blindly starts peeking away at it

some error checking and some tracing would go a long way

barneyman 21-May-15 5:20am View

oh - you just want to talk to a SQL database from C#?

that's EASY ...

barneyman 20-May-15 22:03pm View

what are you trying to achieve? there's plenty of example code in there to create, replay and examine traces ..

barneyman 17-May-15 5:40am View

for the love of cheese, please no-one visit that link - this *post* is itself a phish

by following the code comments, and sms'ing it?

barneyman 12-May-15 21:17pm View

you'll probably find that having tn > ~Number of (virtual) chips won't yield any performance increase - additionally, if they're all hitting the disk, you may get concurrency issues in the OS and DiskElevator - multithreading performance improvement is not simply a case of throwing threads at it, you may need to rethink your IO strategy

barneyman 11-May-15 23:33pm View

no problem - i only suggested it because i have some code i wrote with some extremely angry comments about just this sort of behaviour because of DC corruption

barneyman 11-May-15 0:08am View

sounds like a GDI leak :)

you ARE re-selecting the old font back into the DC before you destroy it?

barneyman 2-May-15 9:13am View

yes - pki/x509 are about key exchange for streaming (normally) encryption .. it could be used for anything

barneyman 30-Apr-15 20:45pm View

i don't think the arduino family has either the stones or memory to handle PKI/SSL - the rpi has OS suppport for it

barneyman 29-Apr-15 23:17pm View

one example of pseudo-encryption, that MAY be useful, but is by no means truly secure is something like ...

Implement the mersenne twister (or similar RNG algo) on the arduino - during commissioning for a particular 'site' all devices store the same random number in the nvram - this number represents the seed number for the RNG algo - when any device on the same 'site' wants to send, the first 2 bytes are a random number, this represents the offset into the RNG sequence that both the sender and receiver need to align to - then you simply continue along the RNG sequence XOR'ing with your data as a one-time-pad analog

you get inferred authentication (because the nvram number has to match within the same site) and encryption

*not foolproof by ANY means, and can be compromised by getting the site number, but may be enough for your needs*

barneyman 29-Apr-15 22:58pm View

- SSL is just the negotiation of a 'secure tunnel' through which any protocol can travel
- x509 is not peculiar to SSL, that's where it's most widely used, x509 is also used in code-signing for instance
- the key TYPE is defined in the x509 - it's intended use, and algorithm it's good for ##
- you misunderstand - each sender encrypts with the OTHER'S public key, the server is encrypting using the temp public key you generated, you are encrypting with the servers public, a MitM attack requires knowledge of one/both PRIVATE keys
- you need to understand the above point and the implications - the private key never leaves the owner

PKI/SSL is a very big hammer to be wielding in a arduino environment - i'd suggest you look for alternative approaches - your primary problem is key exchange (for symmetric encryption)

## asymetric (PKI) encryption is VERY slow, so typically what happens in the credential/key-exchange/message-exchange phase is a random symmetric key is generated, THAT latter key is used to encrypt the data (because symmetric encryption is very fast), the symmetric key is encrypted using the asymmetric encryptor and handed over

32bit code will quite happily run on 64bit machines, what you can't do (as per the OP's problem) is run 32bit DLLs from a 64bit process

i understand what you're trying to achieve, and while i can't help you, i would make the following observation - what you're trying to do is not a familiar (windows) UI mechanic, scrolling while dragging is traditionally done by hovering over the head/tail of the listview

you risk spending an age implementing something no-one's going to use - remember, shipping beats functionality, every time

run it under a debugger, its only ~30 lines of code, and it's not complex - it should be easy to work out where it's going wrong

your cluster_mutex is killing any parallelism

those thread functions are members of the class, they have explicit access to the vector/int already - you're already calling the mutex

i'm not sure i understand your problem/required solution

barneyman 16-Apr-15 7:52am View

i'd GUESS you're trying to access a member 32 bytes into the vtable/offset of a class, when the instance is NULL; look at the stack trace, and work back to your codebase - should stick out like a zit

what you've implemented is a basic recursive mistake - you CAN call a contructor from itself, in the same way you CAN call a function from itself - but if you do that you need to method of 'short-circuiting' out, or you'll run out of stack

barneyman 13-Apr-15 1:58am View

no - you can't de-allocate this memory because you've created a recursive, infinite loop - it needs re-engineering ... quite WHY you're instancing a new Employee inside the constructor baffles me

with reference to your comment about mem-mapping ...

DLLs share the process memory *of the process they're loaded into* ... they do not have their own - so you can't share memory between processes and (similarly) you can't share memory between DLL's loaded in the different processes

knowing nothing about your tables, i'd suggest you have some serious index/locking/contention issues - 50x concurrent use is easily within the capabilities of SQL - you ARE doing this with SPs?

Run a trace (while scaling access) and find out what's taking so long

store them sorted, binary search them to find your lowest, continue ascending until you exceed your highest - your worst case search is O(log n)

without the PDBs and source, there's not much you can do to either find the problem (unless your x86 assembly knowledge is tremendous) and NOTHING you can do to resolve it

That said, the fault is because the code used LeaveCriticalSection using a critsec object it didn't own - the reason for that can be legion, crap code, memory corruption to name the two most likely

barneyman 18-Mar-15 22:19pm View

as SA notes, 'time' in a multithreaded/multicore OS is a thorny issue - your program could appear to run for 5 seconds, but did it use the CPU for all that time (probably not), if it used 10CPUs for 20% of that time, did it run for 10 seconds? How much of *your* runtime was you, and not the Exec running/sleeping/spinning

Similarly with memory - do you want to know how much your code 'used', or how much was allocated to you by the OS, do you mean real memory, or virtual memory - do you wish to include your static/code/stack in that

Simply calling HeapSize and QueryPerformanceCounter (in windows) will give you results that are simultaneously right, and wrong :)

barneyman 12-Mar-15 1:44am View

guid is the correct solution if you want it globally unique - why does the fact it's a complicated string (it's not a string, that's just how the UI renders it) matter?

barneyman 10-Mar-15 23:57pm View

where are you stuck, how far have you got?

barneyman 9-Mar-15 20:01pm View

are you saying you want to *duplicate* tblEmployeeInformation into tblEmployeeLoginDetails? that's fundamentally the wrong way to do it

your tblEmployeeInformation should have a primary, unique key that is then used by tblEmployeeLoginDetails to refer to them, so in your example above (assuming txtIDNumber is their unique employee number), tblEmployeeLoginDetails should have column txtIDNumber which your second INSERT adds, then you can use INNER JOINS to consolidate the two tables

barneyman 9-Mar-15 18:52pm View

done something similar using xslt to transform into a 'common superset' which then gets parsed/queried - actually, cheated slightly, had an xlst v1->v2, xlst v2->v3, etc etc

Meant that any change velocity only affected the parser (for the 'latest' schema), and an additional xlst to go vlast->vnow

so have your insert accepts NULLs and do it 4 times

null,null,value,null
null,null,null,value

barneyman 2-Mar-15 23:06pm View

i don't know the specific solution to your problem, but i do know that blob handling in the SQL client is normally limited to one per returned rowset (NOT one per row), so you'd have to do 4 discrete inserts and 4 selects

i'd also check your columns do have 4 different pics in them - use DATALENGTH to find out how long they are, and put 4 different sized pictures in

barneyman 2-Mar-15 18:57pm View

you're mixing two interface mechanics there - IDL refers to the use of COM, where you'd instantiate a COM object via CoCreateInstance

LoadLibrary is used for getting to exported (via .DEF files) classes/functions

the latter is quick and dirty and suitable for most 'old school' forms of DLL use (C/C++ consumption), the former is much more flexible (C, scripting, etc consumption), but 'troublesome' to understand properly

which do you want?

you're reading and writing into the same file, you're overwriting data you haven't read yet

it would be much more efficient to create an in-memory array/buffer, read a row from file, write a column to memory, then when done, dump the array to file

should you not 'break' from the inner loop if you find a match?

barneyman 15-Feb-15 18:01pm View

this is a common misconception when handling dates in SQL - SQL itself does not NEED to understand the locale for a date - it just stores a generic dateval given to it by the client, either directly (shudder) or via sp's - conversely, it's up the client to present the data the way the client expects - remember 5% of the planet show the date backwards :)

So, your client piece should do the heavy lifting of ensuring the right format is interpreted before going in

also, good practice to stores datetimes as utc
