Placing a floating list box over a text box [Resolved]

[sbasak]

I'm trying to write a word completion program. For that, I have to place a floating listbox over a text box. The list box should move as the user types in text box.

I can't figure out how to get the current text (where the cursor is) x,y co-ordinates from a textbox.

I know that in VB6 it would have been solved by SendMessage API but I've no idea how to do it in VB.NET.

I tried to call the same API in .NET as well, but unsuccessful

Any help?

thanx
