Problem to draw a bitmap

I tested a program ( an other one, with source code this time )
On my Windows XP system I have no problem.
When I use Wine I just get a window. ( where is my bitmap ? )
Then I tried this : "WINEDEBUG=gdi wine progtest" and as Wine is slower
I could see my bitmap, which disappeared as fast as it appeared...

Here the source code :

>   hDC=GetDC(hWnd);
>   DrawState(hDC,NULL,NULL,(LPARAM)hBmp,NULL,0,0,0,0,DST_BITMAP);
>   DeleteObject(hBmp);
>   ReleaseDC(hWnd,hDC);
