InStream.READ wrong behavior

JAJ

Hi everyone.

I need to process big files in "textmode" = FALSE. I have the code bellow :

InStr = InStream
size = Integer
BigTextFile = BigText
TempText =Text 1024
...

WHILE NOT InStr.EOS DO BEGIN
size := InStr.READ(TempText, 1024);
BigTextFile.ADDTEXT(TempText);
END;

BigTextFile.WRITE(OutStr);

...

With this code if the file is multiple of 1025, it only process 1024 bytes.

If I put the code bellow :

...

WHILE NOT InStr.EOS DO BEGIN
InStr.READ(TempText, 1024);
BigTextFile.ADDTEXT(TempText);
END;

BigTextFile.WRITE(OutStr);

...

I get the error bellow :

The stream cannot find a zero-terminated string.
The stream may be invalid....


Anybody knows what is the problem??

Thanks in advance!

Regards.

I just tried it on nav 2009 r2 and it works correctly;

myfile.OPEN('C:\Temp\TADA.TXT');
myfile.CREATEINSTREAM(InStr);


WHILE NOT InStr.EOS DO BEGIN
SIZE := InStr.READ(TempText, 1024);
//BigTextFile.ADDTEXT(TempText);
MESSAGE(TempText);
END;

it returned the first 1024 characters then the last digit.

my file was

11111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111

Hi ara3n,

Thanks for your response, but in my NAV cliente runs wrong. Could you tell me which version of Dynamics NAV R2 do you have?

Thanks in advance.

I used finsql.exe 6.0.32012

Hi,

I used 6.00.32900. But I think that your test it was not correcty. Your file is 1026 kb, and with this size runs ok, Could you test with a file with 1025 kb?

Thanks.

Yes, I just tested it with 1025 bytes and I can replicate it. It's a bug.

I tested it on RTC and I did get two message boxes in classic I only get one message box.

I suggest to report it to MS.
