Looking at the code it looks like you are attempting to compare a previous image with the current image and then determine if the changes are a car?

Not my area of expertise really, but it looks like it could have a few issues.

Working out what is a Vehicle ( not a tree moving )

but if you could better form your question we may be able to help some more.

You can do this if you setup a Windows network correctly, this will allow you to limit the printers that people can print to etc.

Alternatively if I understand you correctly, you wish to to write a handler for windows printing and when the user tries to print you want to ask for a username and password? ( This option is fairly difficult and requires manipulating Windows ) I certainly don't have any code you can have as that is not what this site is about, you haven't even provided anything that you have tried.

You could do with capturing the picturebox.image into an image, then learning about comparing images. etc.

did this work for you? if it did can you mark as solution.

Create a shortcut to the application.
Right click on the shortcut, select properties
go to the compatability tab
select run this program as administrator.

if there is a button change settings for all users click that and check the box run as administrator.

click ok a couple of times, all should work.

you could set the run as administrator in the application shortcut.

you could look at setting up a Database server cluster, this would give you load balancing I believe. but also upgrading hardware may benefit you some what.

SQL server has clustering built in provided you are not running SQL express editions( to the best of my knowledge ) and clustering provides failover in case one goes belly up the other will continue, and also load balancing under many connections.

Yes I agree but nothing to say that the central server couldn't post to the database then pass the other user a link to that file.

If you want to send files through a database you need a way to store the byte data in a database, which involves storing the file in a byte array and then writing a stored procedure to accept the byte array as an argument and store it in the databse.

maybe you should use & instead of +

how do you create an instance of your class?
do you create an instance display what you want then just leave it.

try calling close display in your dispose method.

let me know the results.

Try

dim disp as new yourclass
disp.displaytotal
disp = nothing

you would need to look at using some form of GSM modem, and the appropriate commands, search codeproject for GSM Modem.
Using the method you are at the moment you will only be able to send an email.

How are you getting the text to print to the dot matrix? are you appending any characers to the end of the string you are sending to the printer.

The dot matrix will be responding to ascii characters 10 and 13 which are line feed and carriage return. vb has a character which is vbcrlf which may be appended to the end of text, you may need to remove this/these characters

Well answered that programmer.

Cheers for that Dave, I was just thinking he may have set up a DSN and it couldn't find it.

The things you are asking for are quite dodgy, I certainly think that nobody in this forum will advise you on how to do this. Do you have a legitimate reason for doing this?

can you post the full error message? do you hav e a system DSN defined?

Nicely done, saved me having to type it +5

Is this all files within the sub folders as well as the main ( root ) folder?

Can you clarify what you want to do, simply providing a list of FTP commands does not tell us what you want to do so at present we are unable to help.

Do you have access to the other machine, is it part of a coporate domain, ?

you need to not send a line feed chr(10) or line feed carriage return chr(13), can you show us your code?

you could try looking at service flags, but windows 7 does not allow you to have a user interface for a service application. maybe use the registry to communicate or a text file between a windows app and the service.

does your database column allow you to insert nulls?

The xml serialisation will not serialize a byte array, and the ms documentation is for rocket scientists. So rather than ask someone to code for me, i was trying to get some pointers to some humble human guides.

Medhi has pointed me at something that works but i would like to learn more about serialization. I can use the serialization in the full blown framework alright, was just struggling with. Net compact framework

does what you are getting back from the server match what is stored on the server?

I don't like where this request is going, Captcha has been created for a reason, primarily to stop people creating applications to signup for things.
I'm in agreement with answer 1, If there was a way it would probably not be public knowledge and they would make Captcha's harder to read.

are you calling listview.items.add( your item )

Depends what part of the registry you wish to access, you can use getsettings and setsettings to write to the Vb\VBA key for current user. without elevated priviliges

You need to set form start position to centrescreen in the properties at design time.
Maybe you should have a think about how you would reflect the current time, you know that label1 = time.now, when form loads, should you be updating this to reflect the current time.

Always use you friendly search engine. I use google.

Resolved, thanks everyone for the pointers, it was depth that was causing the issue.

Have you installed the crystal reports runtime, on the client pc.

How are you getting your data back from the database, if you use a dataadapter, you can specify a different query with a parameter

A bit vague, can you be more specific, are you trying to capture within your application? or are you trying to do this on the desktop? what have you tried?

looking at it, i would have said MailMsg.To.Add(mail_txt.Text.ToString()) as it looks like he is trying to reference a text box but enclosing the textbox name in quotes.

The string maybe in protected memory space, but thats just a guess

finally got it sorted

try - Select stdnames from tblStudents where AdmDate >= '" & dtpFrom.value.tostring & "' and AdmDate <= '" & dtpTo.value & "'"

it should auto convert the string to date.

have you ran the crystal reports redistributable setup on the client machine?

have you put the fields on your report in details or in headers?

I hadn't set the image in an on paint event I had set the image at design time, after some messign about, I resolved this see answer below.

Cheers Dave!, I'm not very good at spelling.

How are you creating the socket for TCP Client on the server?

More information needed thats fairly vague,

is it a windows or web app

are you wanting computer names, or usernames?

What version of vis studio are you using? and surely if you are subtracting the fields that are false do you not need to sum all of the fields that are false,
looking at your formula what your are saying is format this into currency, Sum( str( Field!ServiceCost)) - (str(Fields!ServiceCost and Fields!Confirmed) ) this isn't logical buddy.
what type of field is servicecost in your access database, ? more code needed.

do you want to do this in a query or in code, because it would be far easier to return the result from DB see answer below.

you can also set windows position always on top in the form designer.

Should be relatively simple, you could just store the entry date in the last field using getdate(), then using a query like this

SELECT * FROM TBL_ACCOUNTS
WHERE ENTRY_DATE BETWEEN CDATE('01-06-2009') AND CDATE('30-06-2009') ORDER BY ENTRY_DATE

that may work it does for me anyway, but i use SQL Server

Undoubtedly the better example,

somewhere close

you can enumerate list of open windows and get a handle to the window, from the handle you can get the window title, heuristics is a big field and thats why antivirus software is complex. I wish you luck, as It was quite some time ago way back in VB6 that I did something similar,

you may just need to change the conenction string to point at your central database, but I could be wrong which is why i haven't answered, I imagine depending on what you are doing you may start running into record locks.

I don't understand why you query the database and then don't appear to use it, and it would be most helpful if you could explain a little better what you want to acheive.

A bit harsh to be honest, they may just be learning, and I have seen sloppier coding than that in the real world. But I also understand where your coming from.

you need to know how the scales communicate, baud rate etc, before you can begin

Do you have, the code for SCP transfer, I can give an example of the service, but never communicated by SCP from a windows APP before.

I agree, maybe do some downloading trials, depends what you want to do with your website if you wanna deal with credit cards, you need to make sure its incredibly secure, if you just want dynamic content, not so secure, as smithers said, be more specific, It's like saying I want to build a car, what do you want it for? Who's gonna drive it? etc.

I always add user controls dynamically, becuase I had a similar issue in the past. Good luck.

I use selecteditems which is an array of the items selected, its a little quirky but i find it normal now, makes handling multiple selects easy

people happily providing help with coding, but you do have to make a reasonable effort.

Absolute legend don't why i didn't spot it, thanks ever so much.
