Help, I don't know what is wrong with this code,
but when I Display it in a Window, it's nothing happen, the pictures doesn't come up.
WM_PAINT seems find I try with single pictures it's works.
Many things I cut in here the original code is more complex, but I think noone will see it if too long.
do I miss something in here ?
HBITMAP DrawCityMap(int Width,int Height)
{
int a;
char TerrainFile[150]="C:\\Data\\Pic\\Terrain\\Grassland.Bmp";
char FacilityFile[5][150]={"C:\\Data\\Pic\\Terrain\\Jungle.Bmp","C:\\Data\\Pic\\Terrain\\Craters.Bmp"
,"C:\\Data\\Pic\\Terrain\\Desert.Bmp","C:\\Data\\Pic\\Terrain\\Ice.Bmp","C:\\Data\\Pic\\Terrain\\Volcanic.Bmp"};
HDC hDC=CreateDC("DISPLAY", NULL, NULL, NULL);
HBITMAP hBmp,hBmp2;
HDC hComDC1,hComDC2;
hBmp=(HBITMAP)LoadImage(hInst,TerrainFile,IMAGE_BITMAP,Width,Height,LR_LOADFROMFILE);
hComDC1=CreateCompatibleDC(hDC);
SelectObject(hComDC1,hBmp);
for(a=0;a<5;a++)
{
hBmp2=(HBITMAP)LoadImage(hInst,FacilityFile[a],IMAGE_BITMAP,Width,Height,LR_LOADFROMFILE);
hComDC2=CreateCompatibleDC(hDC);
SelectObject(hComDC2,hBmp2);
StretchBlt(hComDC1,a*Width/5,0,Width/5,Height,hComDC2,0,0,Width,Height,SRCCOPY);
DeleteDC(hComDC2);
DeleteObject(hBmp2);
}
hBmp2=(HBITMAP)GetCurrentObject(hComDC1,OBJ_BITMAP);
DeleteDC(hComDC1);DeleteDC(hComDC2);DeleteObject(hBmp);
DeleteDC(hDC);
return hBmp2;
}
here is the window Procedures call that function :
case WM_PAINT :
{
HDC hDC=GetDC(hDlg);
hCity=DrawCityMap(400,400);
hComDC=CreateCompatibleDC(hDC);
SelectObject(hComDC,hCity);
StretchBlt(hDC,10,10,400,400,hComDC,0,0,400,400,SRCCOPY);
DeleteObject(hCity);
DeleteDC(hComDC);
ReleaseDC(hDlg,hDC);
};break;
