hey guys im trying to program something which involves drawing out a waveform graph (no not a mathematical graph) just a view. Now i have it successfully working in wondows 7 32bit under VS 2010 but in windows xp 32bit it complains.
now i found the root of the problem is that i cant generate a single bitmap greater than 32767 pixels long in windows xp. The bitmap is only 50 pixels high and greyscale. Ofcourse im not showing the entire image on screen that would be pointless. What im doing is im showing 190 pixel wide sections of the image over an iteration where the image moves 190 pixels to the left (very efficient for process loops). But for some bizarre reason windows xp complains about it even tho the width and height variables are defined as "int32" as defined by msdn. In windows 7 its perfectly fine, images are produced higher than the maximum unsigned 16 bit value.
So:
1 is GDI different between OS's and
2 how can i force GDI in windows XP to generate bitmaps higher than 32767 pixels?
thanks!
