Error with CopyFile function

Hi,

I just want to copy a file to a destination and it doesn't work.
The Very simple code is :
#include "stdafx.h"
int WINAPI WinMain( HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
CopyFile((const unsigned short *)".\\toto.txt", (const unsigned short
*)".\\toto.bak", FALSE);
return 0;
}

I'm under Windows CE 5.0 and my IDE is Micorsoft eMbedded Visual C++ 4.

If I use the GetLastError() method, the code is 2 (ERROR_FILE_NOT_FOUND).
But toto.txt is present at the good place !!

what's wrong ??

The fact you have to do that ugly cast to get it to compile should be a huge
clue that you're doing it wrong. You might want to read up on Unicode and
TCHAR macros. CE also doesn't have a working directory or relative paths.

CopyFile(_T("\\toto.txt"), T("\\toto.bak"), FALSE);
