After MetaEditor Update my script have erros

bisewski 2014.02.06 17:24

Hi Everybody.

I dont understandin why my script that ran perfectly now have erros.

My metaeditor was updated to 5 but not to mql5, continue being mql4.

But now I have an error here:

 string PipeName = "\\\\.\\pipe\\Perpendicular_as_Client";
        int PipeMode = PIPE_TYPE_MESSAGE|PIPE_READMODE_MESSAGE|PIPE_WAIT;
        hPipe = CreateNamedPipeA(PipeName,PIPE_ACCESS_DUPLEX,PipeMode,1,1024,1024,NMPWAIT_USE_DEFAULT_WAIT,NULL);
        if (hPipe == INVALID_HANDLE_VALUE) {
                Print("CreateNamedPipe failed");
      return (-1);
        }

This code always run perfectly and now, after this update, get error.

Any change happens in new version? The exactly version is 5.00 Build 883.

Thanks

Please read a little MetaTrader 4 Build 600 with Updated MQL4 Language and Market of Applications Released

You have to replace CreateNamedPipeA (ansi version) with unicode version.

opa, thanks, I change to CreateNamedPipeW and work ok.

This function was changed too?

if(FileWriteString(ExtPipe,Quotes_From_APP,size_str)<size_str)

Before, this save in a .csv file numbers like this: 2014.02.06,12:35,1.36047,1.36051,1.36052,1.36041

Now, the numbers are being saving like this: 2 0 1 4 . 0 2 . 0 6, 1 2 : 3 5, 1 . 3 6 0 4 7, 1 . 3 6 0 5 1, 1 . 3 6 0 5 2, 1 . 3 6 0 4 1

Maybe, not necessary is an space in the numbers, maybe other because in the csv file the sequence continue correct, without spaces, but when I read this value with my vb.net applicative, this spaces are read.

Sorry my english, I am with difficult to explain my problem.

That's not a space, that's a null (ASCII zero), strings are now Unicode.

ok, solved, thanks all.

sorry but I continue having problems.

 int ShareMode = FILE_SHARE_READ | FILE_SHARE_WRITE;
                int fWrite= CreateFileW(FullName, GENERIC_WRITE, ShareMode, 0, CREATE_ALWAYS, 0, 0);
                if (fWrite == INVALID_HANDLE_VALUE)
                   {

                      int BytesWritten[1] = {0};
                      
                      //Buffer_Old = "2014.02.06,12:35,1.36047,1.36051,1.36052,1.36041";
                      int szData = StringLen(Buffer_Old);
                      //WriteFile(fWrite, MulDiv(Buffer_Old, 1, 1), szData, BytesWritten, NULL);
                      WriteFile(fWrite, Buffer_Old, szData, BytesWritten, NULL);
                      CloseHandle(fWrite);

Buffer_Old have 200 lines like 2014.02.06,12:35,1.36047,1.36051,1.36052,1.36041 that I save in my .csv file.

The problem now is that only the middle, 100 lines are saved. If I put 500 lines, only 250 are saved. With this change ansii to unicode, I dont understanding where is the problem...

thanks

Is this function use ANSI or UNICODE string ?

                      WriteFile(fWrite, Buffer_Old, szData, BytesWritten, NULL);

How are you checking the number of lines of your CSV files ?
