Re: [Dev-C++] Loading a bitmap and getting its handle ???

Thank you for the hint !!! :)
But now I have an other problem...
I get two different types of handles (HWND and HANDLE).
BitBlt needs for source and destination the handle type HDC.
So the only way to get this code to run seems to cast the two handles to H=
DC.
But BitBlt returns False and nothing is drawn to the window!


void wndAnfang::drawSchein(){
  HWND hnd_Window;
  HANDLE hnd_BMP;
  
  if(hnd_Window =3D FindWindow("fltk", "AB-Sys")){
    if(hnd_BMP =3D LoadImage(NULL, "F:\\Sources\\DevCpp\\Sys\\out\\Schein-=
Small.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE)){
  
      bool b =3D BitBlt((HDC)hnd_Window, 0, 0, 300, 300, (HDC)hnd_BMP, 0, =
0, SRCCOPY);

      DeleteObject(hnd_BMP);
  
      message("%d %d %d",b,hnd_Picture,hnd_Schein);  
    }  
  }  
}
