I have some Windows questions need to be helped with. 1. The 'wsprintf' function doesn't support floating point data, whatelse can be used to print a float type data into a string? 2. The EDIT controls don't seem to be able to handle more than 64k text data directly, how can one use edit control to handle a large file? 3. Is there any way to switch between different resolutions and color modes dynamically? For example, I need the 640x480x256 mode to display medical images but usually the 256 color drivers are too slow to be used comfortablly to develop programs, a 800x600x16 driver is better for that. So, it will be more convenient if one can change the display mode dynamically. Any help will be greatly appreciated.
