Hello everyone. What I want to do is this: create a program which takes a number of bitmaps, each having a name formatted as name0000, name0001, etc, and loads them one by one. It then takes each of these bitmaps and tiles them into a grid with a 1 pixel border between each. Then, saving would be a nice option but not necessary (I could just use printscreen). I don't care if it uses a dialog or SDI or whatever.
Unfortunately, I have pretty much no experience with HBITMAPS and the like, and I'm not sure how to get started. I'd appreciate it if someone could get me started on the riight track.
Thanks a lot!
Gabe S.

Next is small programm for display
bitmap to screen. Enumerate all bitmaps in you dir (FindFirstFile/FindNextFil
make coordinates and use this programm
for each Bitmap for every coordinates :
void DisplayBitmap(HINSTANCE hInst,HDC hdc, char *szBitmapName, int x, int y)
{
BITMAP bm;
HDC hdc1 = CreateCompatibleDC(hdc);
HBITMAP bmp = (HBITMAP)LoadImage(hInst, szBitmapName,IMAGE_BITMAP,
0,0,LR_LOADFROMFILE);
GetObject(bmp,sizeof(bm),&
SelectObject(hdc1, bmp); //select
BitBlt(hdc, x,y,bm.bmWidth,bm.bmHeight
hdc1, 0, 0, SRCCOPY); //display
DeleteDC(hdc1); //delete context
DeleteObject(bmp); //delete object
}
Of course, it is only 1-sr step in you
Apps.
I hope, it helps. Alex

okay you can load the bitmaps from file using ::LoadImage()
you can get the size of the bitmap using ::GetObject() to fill in a supplied BITMAP structure
you can BitBlt the bitmap by selecting it into a device context and then BitBlt'ing it onto the screen
There are many examples on the above
Keywords are LoadImage, GetObject, BITMAP and BitBlt
If you need help on any of the steps please ask
