BMP
I'm currently programming under windows in c++ 4.5 by borland, my problem is that i can't get aany kind of BMP to display, and was wondering if you would have any ideas on how to write the code to display a BMP of any kind.

Note that that technique relies on the fact that LoadBitmap() or LoadImage() return device dependant bitmaps (DDB) for the display. If you need to drtaw on other devices, like a printer, you will need to use device independant bitmaps (DIB).

1. You probably already have a DC for the screen, or window that you want to draw to (if not let me know) but you need to create a compatible memory DC, using CreateCompatibleDC().
2, You need to load the bitmap with LoadBitmap() or LoadImage().
3. Select the new bitmap into the memory DC with SelectObject().(saving the previous bitmap handle so that it may be selected in when you are done.
4. Copy the image from the memory DC to the screen DC using BitBlt() or StretchBlt().
5. You are now done, but you have to clean up.
6. Restore the saved bitmap to the memory DC with SelectObject().
7. Destroy the memory DC with DeleteDC().
