I have an EditControl that, when the text changes, checks whether it's focused (there is a secondary EditControl that does exactly the same). I searched the forums and found the GetFocus function via SetFocus, but the function doesn't seem to have any parameters. What I need to do is something like:

code:

---

if(Interop.Call('user32','GetFocus',EdtBox.Handle)){
//do stuff
}

---

Is there some way to do this?
