lstrcmpi() behave differently on XP and Vista

[dipaksmistry]

Hi,

I have written a small programme in VC.

Its code is as below.

####################################################################################################

###########

#include "stdafx.h"

#include <tchar.h>

#include <Shellapi.h>

#include <malloc.h>

#include <stdlib.h>

int APIENTRY WinMain(HINSTANCE hInstance,

HINSTANCE hPrevInstance,

LPSTR lpCmdLine,

int nCmdShow)

{

TCHAR t3[15];

t3[0] = 65279; // equivalent to 0xFEFF, (in my real application this byte is read from a unicode file

// in UTF-16 format and its value is 0xFEFF)

t3[1] =_T('a');

t3[2] =_T('b');

t3[3] =_T('c');

t3[4] =_T('d');

t3[5] =_T('e');

t3[6] =_T('');

if ((lstrcmpi (t3,_T("abcde"))) == 0)

{

MessageBox(NULL,_T("two strings are equal"), _T("match result"), MB_OK);

}

else

{

MessageBox(NULL,_T("NOT EQUAL"), _T("match result"), MB_OK);

}

return 1;

}

I have build it and made a executable.

Not when I run this executable on XP machine(with SP2 installed), it gives messages one.("two strings are equal").

string comparison passes on XP machine.

But when I run this application on Vista machine it gives second message.("NOT EQUAL")

string comparison fails on Vista machine.

Do anybody have any idea, why this is happening....?

i don't think we have many coders on teh apps forum here, your best bet is the the MSDN forum over at MS, have you checked teh Vista SDK to see if the functionality was changed in vista?

different version of the c runtimes? is this compiled in .net or c++6?

t3[6] =_T('/0');
