Selected text in a active window problem. help!

hello experts. i am starting to write a dictionary software. It should be lunched when the user select a text in any other programs and then press an especial key (For example Alt F10) . Such as Babylon Dictionary.

My problem for now is how to access the selected text in an active window. i am new in vb.net. please help me. pretty please :cry:

If you're new to vb.net then this is not something to be starting on. It involves a detailed knowledge of the Windows API and requires intercepting basic Windows functions.
