Extract file from resource in Windows module

Question

The below code executes, but it only extracts an empty bitmap file. Any ideas as to what is wrong with it?

void Extract(WORD wResId , LPSTR lpszOutputPath)
{ //example: Extract(IDB_BITMAP1, "Redrose.bmp");
    HRSRC hrsrc = FindResource(NULL, MAKEINTRESOURCE(wResId) , RT_BITMAP);
    HGLOBAL hLoaded = LoadResource( NULL,hrsrc);
    LPVOID lpLock =  LockResource( hLoaded);
    DWORD dwSize = SizeofResource(NULL, hrsrc);
    HANDLE hFile = CreateFile  (lpszOutputPath,GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);
    DWORD dwByteWritten;
    WriteFile(hFile, lpLock , dwSize , &dwByteWritten , NULL);
    CloseHandle(hFile);
    FreeResource(hLoaded);
}

Answer 1

You are asking for RT_RCDATA but I bet you didn't add your bitmap via a RCDATA statement. You probably added it via a BITMAP statement, which makes it RT_BITMAP.

In the future, please state which step failed rather than making people guess.
