Hi,
I have written a small programme.
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('\0');

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....?
