Find textbox in window

Hi,

I want to use API functions to find a window that appears when I run a program. So let's assume I do that. Now there are three different textboxes in the window and I want to send some text to them. I don't want to send same text to all of them, instead one textbox should get one text string, the other one some other text string and so on. Now the problem is, how can I locate every one of those textboxes? How can I know which one is which one? I use a "Window Finder" tool that gives me the class name of every object in the window, but the textboxes have of course same class names (Edit) and I don't know what is unique for every such textbox (the handle changes from time to time, so I can't search for the handle :S).

Thanks in advance!

Ok I made it work. This is the code that loops for 3 textboxes and fills them with text:

VB Code:

'temp is the handle for the parent window
Do While nbr <= 2
     lhWndChild = FindWindowEx(temp, lhWndChild, "Edit", vbNullString)
     If lhWndChild Then
          nbr = nbr + 1
          If nbr = 1 Then
               iii = SendMessage(lhWndChild, WM_SETTEXT, 0, ByVal "Text1")
          ElseIf nbr = 2 Then
               iii = SendMessage(lhWndChild, WM_SETTEXT, 0, ByVal "Text2")
          Else
               iii = SendMessage(lhWndChild, WM_SETTEXT, 0, ByVal "(""*"")")
          End If
     End If
Loop
bWnd = FindWindowEx(temp, ByVal 0&, "BUTTON", ByVal "Apply")
iii = SendMessage(bWnd, BM_CLICK, 0, ByVal "0")
DoEvents

But now there is a strange thing that happens after the Do-While loop. I manage to find the "Apply" button and click it, but the program gets stuck after that step (that is, after SendMessage(bWnd, BM_CLICK, 0, ByVal "0")
). Do you have any idea of what it might be?

Very grateful for help.

[Edit]: Sorry for the formatting, don't know how to write real code in here :(

OK I think I resolved this too :)
I use PostMessage instead of SendMessage, and then it works.

Just use the vbcode tags. See my signature for an example. :)
