Thread: Need help with Bitmap Display

This code is expanding on the forger's windows programming tutorial; bmp_one (simply displays a static bitmap of a ball on a screen).

I am attempting to load an array of HBITMAPS (deck[53]) with a bunch of bitmaps of playing cards I scanned earlier today.. and display 5 random cards from the deck onto the main window.

I can get the code to work if I omit trying to load the deck[53] and just btblt( ) one specific card.

Can anyone spot the problemo...??
