Hi netters!
    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.
