Can you use a circular queue to hold updates, then combine 'n' updates into a larger buffer, then write that ?

as realJSOP said ... look, you COULD write LINQ/XML, but then you're still stuck with getting the three different types of result from the result of that - which could be just as painful .. if you really need the LINQ having looked at deserialisation, you would be better off with three queries, assuming the shipping order has only one orderperson, shipto & then the multiple items can be a collection on their own

That appears to be a curly one ! I don't have a joystick, so can't test for you, and searching for a useable project you can use a test/starter is seeming hard at the moment - there's this I found https://stackoverflow.com/questions/3929764/taking-input-from-a-joystick-with-c-sharp-net that may be of some use. Note the response from Valdemar there, sometimes dealing with hardware it's useful to try a simple console mode program to see if you can 'talk' to the hardware before going on to Winforms stuff


One thing, you say 'comes up with errors' .. we can't see your screen, so, that's not really helpful for us - maybe you could see what the 'highest level' error or 'most important' error appears to be and post that (edit your question)

[edit] this https://www.codeproject.com/Articles/16704/Interfacing-with-a-Joystick-using-C might also help as a 'starter' [/edit]

Can you dump/list permissions on the service account at a customer where it does work, then compare against a customer where it doesnt ? (you'd need pretty understanding customer I guess)

Some questions
1) You use "is different then the day before" and "at 11 am on Tuesday the value is 50, if the value is 60 on Wednesday" but don't really clarify the basis for comparison .. are you saying that at 11:00am Wednesday, you wish to check the price 11:00am Tuesday, or, 'end-of-day Tuesday' .. what happens if Tuesday doesn't have a record for 11:00am ?
2) are the time-stamps per day unique - eg for Tuesday there will only be one or none of (time part) 12:34:41 ?

Why don't you write unit tests in Java (I'm sure it possible) .. if you get into that habit then you're setting yourself up well for a professional future ... ideally you would have done it as you added every 'feature'/'function
Garth J Lancaster 6-Sep-20 6:52am View
   
sorry, without seeing the code all I can do is shrug - I can't set up a test from here either .. maybe someone else will understand from your description
Garth J Lancaster 6-Sep-20 6:36am View
   
"but it won't work correctly.' not really helpful - why don't you use Improve question and add the SelectionIndexChanged event handler code you have, try to describe as clearly as possible why it doesn't work, and we'll see what we can do/suggest .. don't fret too much about the 'bad English' bit, we are quite tolerant unless the meaning is obscured, then we can always ask you

I guess you can say 'automatically assigned' - in the sense you rarely/shouldnt have to worry about the details - of course, under the covers, it's a little more complex
1) when the JVM start's up, it requests a 'block' of memory from the operating system (the size of which can be modified/optimised)
2) any requests to 'new' for example are served from this block by the JVM
.... so unless you run out of memory, you usually don;t care too much, it just 'happens'
Garth J Lancaster 28-Aug-20 4:17am View
   
It might be handy to provide more information on the 'size' of "there are millions of records." - use Improve question

At a quick guess, a lot of time could be wasted writing to the file on disk - I would be looking at
1) making the acquire xml 'data' (I'm not going to use 'file' as a term here) async
2) hold the data in maybe an XMLDocument in-memory

This may mean getting smaller sets of XML ie 'batching' rather than one big blob, if it is at all possible, but that's the principle, reduce the 'file' IO, make it async

In addition to everyone else's comments "As you can see this method is not good if multiple users connected at the same time decide to run the same query." .. that's precisely what a database is supposed to do - allow multiple users to access data .. if they are running the same query, then let the database deal with the caching etc.

I'm not sure what your issue with that is, except as OriginalGriff points out below as a solution / fix to your select code.

If your problem is that all users must use the same parameters for the query, that's a completely separate issue - you might need to use a control-table or such to store the parameters for a run, but how you update it/specify a duration in which a set of parameters is valid/the set to use will get 'interesting'

You haven't send 'to what end' you wish to combine the two vectors - what will you do with the result / what is it to be used for ?

"Me? I'd go with the latter" ...yup I used to work with a DBA who would fail code reviews for 'un-necessary CASTing'
Garth J Lancaster 23-Aug-20 22:00pm View
   
iirc, this problem usually occurs, because you have a database table field defined as for example nvarchar(30) eg your txtCharName, but you have a c++ string that is larger than 30 characters - let's say 35 just as an example. So you're getting an error that "Loremipsumdolorsitamet,consectetur" is going to be truncated leaving '...consect' on the end but missing the full 'consectetur'

Does that make sense ?

You're using an 'odd' ie different database layer than I'm used to, so, suggestions for fixing I can only give rough thoughts .. make sure your update parameter sizes match the table field sizes for binary/blobs & string (nvarchar) types .. and/or increase the nvarchar types
Garth J Lancaster 22-Aug-20 23:21pm View
   
I took a quick look at the Stripe API - I saw 'Webhooks' but I'm not sure that will give you what you want. Could you automagically run a report at say 'midnight' each day and use that information to update your database, I'm not sure whether that's invoice data per customer or ? .. if the report data is available, it would be pretty easy to set up a service app to update your database
Garth J Lancaster 18-Aug-20 6:53am View
   
"I would like to know is this a good way i have it setup?" .. well, I would say no - you still want to decouple the trade receive from the processing (so you don't want to block your socket) .. it still depends on numbers and speed (of received trades) - I'd be looking at adding the received trade to (maybe) a shared datatable/data structure, maybe firing off an event to say data has arrived, but then processing that data in a second (and safe) thread - one could use an observable collection here as well ... do you also need robustness ? what happens if you 'drop' a trade ?

It would be nice to see some details of the HTML string ... I see 2 possibilities
1) you clean up the HTML string before your existing routine - so code mostly as it is now, with an extra call to clean up (ie remove the empty rows) .. that could involve parsing the HTML and then deleting the empty rows and returning a string to use as you do now
2) OR re-writing/extending .ParseXHtml() to do this ... although not quite the same, there's some thoughts on this here https://stackoverflow.com/questions/36180131/using-itextsharp-xmlworker-to-convert-html-to-pdf-and-write-text-vertically

Well, if it were me, I would be looking at the locale & keyboard/language settings - eg English/US .. I don't know what Linux comes as standard on a Raspberry Pi3, but I would suggest looking at the 'man' pages and/or net for keyboard issues for your Linux variant

is the inability to access shift 1 ... etc a problem just in nano, or does it fail in the ssh/terminal window as well ? obviously if it works in ssh/terminal, it's a nano problem, if it doesn't work in ssh/terminal, it's a general issue ..

We are more than willing to help those that are stuck: but that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you. And if you hand in work that we produce, you are a liar and a fool - your tutor can also see this site !!!!

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

You don't provide a lot of information .. what else is in this table ?, what are you going to use this information for ??

if you have a product table then sure, it might have a quantity, but does it also make sense to have new and old quantities ? ..

Maybe you need to think about an audit or transaction log, such that, if a PO uses x items, a timestamped audit/log entry is created for each item, showing the new and old quantity - you can then use this for analysis

If you can provide more schema info, better solutions may be forthcoming - Use Improve question to update your question.

so what is your problem ? you'll need to write code to
1) accept numbers from the console (maybe read as a comma delimited string ?)
2) split the string by the comma and store the numbers in an appropriate data-structure
3) iterate the data structure to find the minimum number
when you break a problem into smaller segments, it becomes easier to get help

I don't think you've shown us the relevant parts from which we can help you - for example, what runs after you click the link 'to get to' gameInfo.php ... you'd be correct in assuming that somewhere along the line, the id of the game/link you've clicked on, must be passed into/obtained by gameInfo, so it can then get the further details from the JSON and display those ... but without the relevant guts, we're more blind than you ...

It's *really* hard to find information out there ... it looks like you would do something like this
JET_INSTANCE instance;
JetCreateInstance(&instance, "instance"));

JetSetSystemParameter (&instance,
                               JET_sesidNil,
                               JET_paramRecovery,
                               NULL,
                               (JET_PCWSTR)"Off”);

err = ::JetInit(0);

err = ::JetInit(&instance);

I think you need to check OriginalGriff's reply carefully - especially "That may be as simple as "does the file exist?" or you may have to be cleverer than that and check the file content to see if there is a header line (or indeed any data at all)." - you've been tweaking true to false and back again now - so it's obvious that on it's own is not going to work - hence why I would have written a temporary file and merged it - that way extra header lines could be removed, if you didnt implement smarter logic as suggested
Garth J Lancaster 3-Aug-20 23:51pm View
   
Its not immediately obvious where locationmasterhistory is .. your code seems to show you loading from database table tblCompBranchHistory to a data-table to excel.

The obvious answer, in general, is, use the unique ID's from the data-table for tblCompBranchHistory, and build a paramaterised query to
update locationmasterhistory set export = "yes" where ID in [list]
but I'm not 100% sure of your schema

btw, I suggest updating by 'ID', because in as little info as you've shown, doing an unrestricted update of locationmasterhistory could be dangerous
Garth J Lancaster 3-Aug-20 8:36am View
   
There's not enough requirements really to give you a decent answer eg:
- how many tables ?
- how often does a 'regional' update get sent to the server ?
- how many rows at a time per table will get sent to update ?
- you say the server has a public ip address, great, but how are you going to (potentially) route that to a 'service' to update the master database ?
- what happens if a 'set of data' isnt updated due to some error - is there a backup protocol required ?
- what IS the data - does it need to be secured in addition to securing the communications protocol ?
There are these a a lot more an architect would start asking to start sketching a solution

well, we can't see your screen and figure out 'from where' you got matrix.solve or such - as Sandeep's solution (1) guesses, it could be the JAMA library.

The answer to the first part of your question could be 'you need to look at your import statements, or the Maven or Gradle build files' .. the answer to why is doesn't work in Eclipse is likely that the required library isnt imported or available, so maybe identifying which Java matrix library and how it's being used will give you the clue for the Eclipse issue

sure - what I've got there will save all of lets say the first datagridview dgv to a file. Let's assume that dgv has the first column as a checkbox that if ticked you want to transfer that row to a second datagridview dgv2 - then roughly, build a new datatable dtt with the rows for datagrid2/dgv2, loop through the selected rows of datagrid 1, add those rows to the 'transfer datatable, then set that datatable as the source for the second datagridview dgv2, ...
DataTable dtt = new DataTable();
dtt.Columns.Add("Col1");
dtt.Columns.Add("Col2");
// ... and so on   
foreach (DataGridViewRow item in dgv.Rows)
{    
  if ((bool)item.Cells[0].Value == true)     
  {        
    bool isSelected = Convert.ToBoolean(row.Cells["Col1"].Value);        
    if (isSelected)

Maybe you should use Improve question to add the relevant code, the error text itself, and what 'type' of database you're using - I'd have to guess at MS SQL Server

As it stands, the only information I can offer, assuming you're using SQL server, is that the transaction log records all database modifications and transactions, but will fill up if it is not managed. This transaction log can be used to repair a 'corrupt' database. Where I worked recently we needed to manage transaction logs for databases we received from clients before we could load the database for analysis

yes, its possible, but I dont work with Python all the time, so, at a guess, and noting the blobJson has single quotes in the JSON, try this
blobJson = parsed[0]["blobJson"]
blobJson = blobJson.replace("'", '"')
parsedbj = json.loads(blobJson)
print("[0].x = ", parsedbj[0]["x"])
print("[0].y = ", parsedbj[0]["y"])
print("[0].z = ", parsedbj[0]["z"])
print("[1].x = ", parsedbj[1]["x"])
print("[1].y = ", parsedbj[1]["y"])
print("[1].z = ", parsedbj[1]["z"])
instead of "print(json.dumps(parsed, indent=1))"

My way probably isnt very efficient, there's likely a python library that can do the same, I just 'followed' the data structure after the first parse, pulled out and corrected the required piece (blobJson), than parsed that from json to get a list of dictionary objects

"Can we read specific nodes or filter the reading of xml-" - is that a question ? if so, the answer is apparently not, unfortunately .. it may be the column mappings that are taking time, but I'd have to see it's performance and memory stats really to try and decide

With no details of data.xml, except it seems to have 2 different types of data, what I would try is to reduce the data set size, in a number of steps
1) sufficient data to make sure the process in general works, but maybe 100 records
2) split data.xml into the two types/nodes of data, as individual files - I think this is what you're asking as the first question, but I'd go even further, in that each node in each 'split' by type file only contains as much data as it needs and no more
3) wrap the bulk-copies in a transaction - one per copy ...

[Edit] with a little work, you might also try the WriteToServerAsync method

You Said "this is not working so well" - could you please use Improve question to indicate 'why not' - it may help people know what you need, it is not clear to me exactly what you're asking for

In general, yes, it should be possible - take a look here for example https://www.codeproject.com/Articles/1210189/Using-SQLite-in-Csharp-VB-Net ... if you want a quick critique on 'ModuleOne', ok ..
1) ModuleOne is a bad name and not indicative of it's purpose - vs 'sqliteDBModule' for example (I forget the VB 'case' conventions)
2) openDB does too much - it should take maybe the name/path to the db, and return a db connection or error (or even throw an exception), that's it - one purpose
3) you could extend your Sqlite 'Module' to implement openDB, closeDB, executeSQL etc etc, but of course I'd say consider what's out there already and re-use/extend it
4) in addition to (3), I'd say, think of 'layering'/'abstractions' .. at the bottom-most layer, you have a sqlite database module that does only low level things with ANY database. 'On Top' of that layer, you then build Module(s) that are specific to the data you wish to handle - One Module per database or table maybe

Does this help or get you any closer to what you need ?

"and failed." & "it still failed." you really need to use Improve question and include how it failed and what the errors were - as succinctly as possible, but more information that you have provided so far - it could be an easy or hard 'fix'

"they did not work:" - that is ambiguous isnt it ? what do you mean by that - did you get no result whatsoever on the serial monitor, or a reading from one of the sensors, or ? - you should use Improve question to update the information and state exactly what that means.

Ok, so, I guess the sensors are wired correctly (in parallel) in terms of the SDA, SCL lines with a pull-up resistor between them and A4 (SDA) and A5 (SCL) on the UNO. They both have different I2C addresses (MLX90614 = 0x5A, VL53LOX = 0x29) by default, so unless you've changed the addresses, it's not that

I see in your combined setup code
void setup()
{
  Serial.begin(115200);
  mlx.begin();  
  
  while (! Serial)
  {
    delay(1);
  }
  
  if (!lox.begin())
  {
    Serial.println(F("Failed to boot VL53L0X"));
    while(1);
  }
}
could you please try moving the mlx.begin(); 'down', so
void setup()
{
  Serial.begin(115200);  
  
  while (! Serial)
  {
    delay(1);
  }
  mlx.begin();

  if (!lox.begin())
  {
    Serial.println(F("Failed to boot VL53L0X"));
    while(1);
  }
}


I'd also ask if you really need the
if (Serial.available())
{
}
around the combined sensor reading code since you wait for serial to be available in the setup code

Garth J Lancaster 30-Jun-20 9:58am View
   
ok, that's a 'different' requirement ... what you need to do is set up an appender for each level -> log file
So, for each level, create a new appender (file, rolling file, whatever) - using 'info' as an example ..
1) name it eg RFAppender-info
2) set the file value to a unique file path/file-info
3) set the filter type to "log4net.Filter.LevelRangeFilter"
4) set the filter levelMin & levelMax to "INFO"
5) add the appender to the 'root' list of appenders
Im sure if you google for 'log4net different file per level' you will find the information if this doesnt make sense

Your issue would suggest that the first and/or last 'node' of your list isn't correct - since you don't provide the code that builds the list I/we can't say.

I am assuming (always dangerous) that this is an assignment/homework of some sort where you must use your own list - else you would just use the STL List implementation and a standard reverse iterator with rbegin && rend, yes ?

I think you should use 'Improve question' and show the code that build's the list and comment why prevNode/curNode and particularly spaceNode exist

I'm not sure what dev environment you're using, but you should also be able to highlight the line that causes the exception (and it will almost certainly have null's where you dont expect) by 'single stepping' through the code - debugging is a useful skill

I'm pretty sure I answered you question "Hi I want to push data in to datadog API, I have datadog API key but don't know how to send data from my window service in c#" ... if you want now to do a GET to receive data, you need to change some of the code

httpWebRequest.Method = "POST";
and

delete
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
    string json = "{...your event data here...}";

    streamWriter.Write(json);
}


Then you'll need to read trhe DataDog API link, and see how to format the request - ie this "https://api.datadoghq.com/api/v1/events" will be different

surely if "might be used in a commercial product" then you can get a trial ITextSharp license and test that (ITextSharp is the only product I know capable of doing this in C#) .. Once it becomes a commercial reality you can then negotiate and pay for a license

I think you should modify (use 'Improve question') your question and give a few more details- eg, 'which' DB server are you using, MySql, SQL Server etc, Maybe 'abridged' schemas etc. It is very hard for 'us out here' to give you an answer based on what you have so far.

I could say 'indexing'/partitioning and/or creating views over your data as a very general technique but likely wrong approach because there isnt enough information in what you have supplied to refine an answer

SELECT to From Flights WHERE fino = 1

"but nothing special so far." really - that is a pretty useless comment, it tells us nothing about what difficulties you had - as Richard pointed out, it's in the documentation - in particular, you can issue a GET for /api/tunnels to your ngrok instance, it it would respond with the JSON below .. it's a pretty simple task to whip up a C# HttpRequest to handle this ...
{  "tunnels": [      {          "name": "command_line",          "uri": "/api/tunnels/command_line",          "public_url": "https://d95211d2.ngrok.io",          "proto": "https",          "config": {              "addr": "localhost:80",              "inspect": true,          },          "metrics": {              "conns": {                  "count": 0,                  "gauge": 0,                  "rate1": 0,                  "rate5": 0,                  "rate15": 0,                  "p50": 0,                  "p90": 0,                  "p95": 0,                  "p99": 0              },              "http": {                  "count": 0,                  "rate1": 0,                  "rate5": 0,                  "rate15": 0,                  "p50": 0,                  "p90": 0,                  "p95": 0,                  "p99": 0              }          }      },      ...  ],  "uri": "/api/tunnels"}

Ok - I would add a HashTable/Dictionary to the DistinctWords Class

Hashtable<string, integer> words;

And Inititialise it in the DistinctWords Constructor

words = new Hashtable<string, integer>();

That will hold each word, and a count how may times it occurs

Then I would add a method for example loadWordsFromFile() That populates the words array with words and counts - you will need to open the file using this.filename, read each line as a string, then split the string into words, maybe based on a space character as the delimeter. For each word, check if it exists in words HashTable, if it doesnt, add it with count 1, else increase the count.

To each of count_distinct_words, count_total_words... methods, add a check to see if the HashTable words has any entries, if not, call loadWordsFromFile().

count_distinct_words, count_total_words can then be filled out by looking at the number of entries in the words HashTable, or summing the Counts of all the Words (The Integer part) aka values of the HashTable.

Then refine this for checking if the words are correct

I think you need to improve your question a little - for instance, why is TEAM2 the Team for Karl here "KARL|TEAM2|2|3|5" ? - ok, it appears to be the last team Karl was in by date or the Max by date ..

Right now I can't see a single query that would do as you ask, I can think of getting a distinct list of names & last team name by date, then using a cursor to iterate through the records for a team member to build the points & dates sections

btw - wtf is 'transponation' ? do you mean 'transposition' perhaps ?

This looks like homework - we don't do people's homework for them.

sorry, I don't know what's going on there - I dont know how 'simply' adding the missing return View(model); statement to fix the first error can cause that .. btw, the first level refactor of your Create I would
public async Task<IActionResult> Create(int id, int type)
{
        InsuranceViewModel model;
        ViewBag.Type = type;

        var companies = await _context.InsuranceCompany
            .Where(e => e.IsActive)
            .ToListAsync();
        ViewData["CompanyList"] = new SelectList(companies, "Id", "CompanyName");

        switch ((InsuranceType)type)
        {
            case InsuranceType.Body:
                model = await insuranceTypeBodyCreate(id, type);
                break;
            case InsuranceType.ThirdPart:
                model = await insuranceTypeThirdPartCreate(id, type);
                break;
            default: 
		// Throw An Exception ?
                break;
        }

        return View(model);
}


Which needs two new functions insuranceTypeBodyCreate(id, type); & insuranceTypeThirdPartCreate(id, type); and I'm sure the logic in each of those for not null vs null could be made 'nicer'
Garth J Lancaster 27-May-20 0:16am View
   
Well, first thing is always to make it work .. add the missing
return View(model); 
so the top block has it, ie
        if ((InsuranceType)type == InsuranceType.Body)
        {
            var bodyInsurance = await _context.BodyInsurance
           .Include(e => e.InsuranceCompany)
           .FirstOrDefaultAsync(e => e.Id == id);

            if (bodyInsurance == null)
            {
                 …
            }
            else
            {
                 …
            }
            return View(model);    // Missing return !!!!
        }
        else
and leave the rest of the code for now. I'll post back later with a cleaner option

I did say it was rough and needed a bit more work, we are not supposed to do all your work for you ... colValue is the bit that you need to fill in, since you didnt really explain 'results in one string' .. you could, for example
using SqlCommand cmd = new SqlCommand("select field from table where value = @Value", maConn);                {                    
  SqlParameter param = new SqlParameter();                    
  param.ParameterName = "@Value";                    
  param.Value = aplSymbol;  // your actual value here                     
  cmd.Parameters.Add(param);
                        
  using SqlDataReader reader = cmd.ExecuteReader();                    
  {                        
    StringBuilder colStr = new StringBuilder("");                        
    while (reader.Read())                        
    {                         
      string colValue = reader["Column/Field Name"].ToString();                         
      colStr.Append(colValue);                         
      colStr.Append(",");                        
    }                        
    return colStr.ToString();                    
  }                 
}

to get a comma separated list of values as a string, and then remove the last
return colValue;
shown in the major block of code.

It's up to you though, to adequately define the problem and what you need

    document.Open();
    PdfPTable table = new PdfPTable(columns.Length);
    foreach (var column in columns)
    {
        PdfPCell cell = new PdfPCell(new Phrase(column, headerFont));
        cell.BackgroundColor = Color.BLACK;
        table.AddCell(cell);
    }
    
    foreach (var item in customerList)
    {
        foreach (var column in columns)
        {
            string value = item.GetType().GetProperty(column).GetValue(item).ToString();
            PdfPCell cell5 = new PdfPCell(new Phrase(value, rowfont));
            table.AddCell(cell5);

It seems like a scoping issue - if you've declared your 'doc' instance local to another handler or such .. you really need to declare it somewhere 'global', so it can be 'loaded' ? Imported in your terms in one handler, then Exported by the handler you're working on ... there's usually a spot somewhere within a WinForms app you can declare such, but Im on a Mac at the moment without Visual Studio, so cant check....

My 'gut feel' is that ApiAppGp is an anonymous type, which as the error suggests, doesn't have AsEnumerable() defined on it - hence the .FirstOrDefault() fails.

As the error message suggests, you could try something line

lastReqName = ApiAppGp.AsEnumerable().FirstOrDefault().LastReqStatusNavigation.Name,


but that still looks/feels wrong. Hopefully someone else will give you a better answer, I dont have time right now to run it up and play with it.

I have to say, looking at your data model, I'd be simplifying it for a REST point of view

[{regionobject},{…}…]
regionobject structure:
{region_id : value,
region_name : value,
region_fullname : value,
region_type : valuee
region_misc : value,
projects: [{projectobject},{…}…]}


Would be two data domains,

/api/regions
/api/projects

and then maybe an aggregator that returns a joined 'set'
