Why do you want to do this?  Icons are intellectual property.  Unless
it's an open source app, you can't just scrape a bunch of icons from
existing applications and gather them into a library.  It's not legal.

Having said that, a few minutes with Google and MSDN would have answered
this question.  LoadIcon returns an HICON.  You can pass that to
GetIconInfo to return an ICONINFO structure, which includes the two
bitmaps that you need to draw an icon.  An icon always includes two
bitmaps: one is a monochrome bitmap that digs the hole for the color
image, and the other is the color image.  Those are HBITMAP handles. 
You can then use GetBitmapBits to get the actual pixels.

It's possible this might be easier in C.
