hi,

I want to create a window where you can "see-thru" it,i.e the contents
of the window below it should be visible.
How can I do this?

Hi,

Well... you can achieve certain kinds of transparency by using
alpha blending, which is part of GDI and GDI+. So, you can use
the following APIs to accomplish that:

CreateWindowEx() WS_EX_TRANSPARENT

UpdateLayeredWindow()

SetLayeredWindowAttributes()

SetWindowRgn()

SetBkMode() TRANSPARENT

AlphaBlend()

TransparentBlt()
