FormatMessage Error

Hi

What's wrong with this code:

void PrintMessage()
{

DWORD_PTR args = (DWORD_PTR)("Test1");

LPTSTR pszResult;
char fmt[MAX_PATH];
strcpy(fmt, "Name: %1!s!\r\n\r\n");

va_list marker;
va_start(marker, "Test11");

FormatMessage(
        FORMAT_MESSAGE_ALLOCATE_BUFFER |
        FORMAT_MESSAGE_FROM_STRING,
        (LPTSTR)(fmt),
        0,
        0,
        (LPTSTR) &pszResult,
        10000,
        &marker);

MessageBoxA(0, pszResult, "Result", 64);

}

I get access denied error, you cannot change first parameter. So tell me resoulution without changing first parameter.

Thanks
