i need help in tweaking blitting sourcecode

graeme · 2002-01-26T07:45:22

and the source code I need to tweak is here: http://www.codeproject.com/bitmap/gditutorial.asp#xx82862xx Now, I realise I am asking quite a lot by asking you to download the zipped file for tutorial 2 and taking a look at it, but I have been trying to crack this all day! What I am trying to do is modify the code in anticipation of using it as the basis for a program which will animate a series of bitmaps. The program initializes and paints the bitmap to the window within functions called by the message handler, WM_PAINT + WM_CREATE. At the moment I am trying to bypass the WM_PAINT call to the gdi02_OnPaint function, and call the function from within winMain instead, but nothing happens. I realise that this is probably due to the scope of the data structures within the functions. During the switch of a message is all data shared? How would I get around this? I realise that it''s a pain to go download a zip file but I would be really gratefiul! Thanks in advance, Graeme.
