Problem to draw a bitmap - wine-devel

3 Dec 2004


      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 :
...
#include <windows.h>
#include <wingdi.h>
void PrintBmp(HWND hWnd, char *filename)
{
  HBITMAP hBmp;
  HDC hDC;
  hBmp=(HBITMAP)LoadImage(NULL,filename,IMAGE_BITMAP,0,0,LR_LOADFROMFILE);
  hDC=GetDC(hWnd);
  DrawState(hDC,NULL,NULL,(LPARAM)hBmp,NULL,0,0,0,0,DST_BITMAP);
  DeleteObject(hBmp);
  ReleaseDC(hWnd,hDC);
}
