Click Button On Other App (AOL Toolbar)

Ok, first off here's my code.  The SetFocusAPI wasn't in there originally and doesn't appear to have helped at all.

Call SendMessage(addresshWnd, WM_SETTEXT, 0&, location.Text)
Call SetFocusAPI(addresshWnd)
Call SendMessage(pns, WM_LBUTTONDOWN, 0, 0&)
Call SendMessage(pns, WM_LBUTTONUP, 0, 0&)

The problem is that visually it works.  I run it, the text is put where I want it in the AOL Toolbar (AOL 9.0)
and when I put a sleep in between the mouse events I can actually SEE it pushing the button and releasing.

Problem is nothing happens.  If I do it manually obviously it does work.  So here I am.. lost.. any ideas?

Have you tried sending a BM_CLICK message to the button?

Yea, I tried that earlier.  I should have mentioned that.

Same result (nothing).  I'm by no means an expert but seeing it visually happen makes me wonder why it doesn't work. :|

I just found out if I put a 3 second sleep between the buttonup/buttondown and move the mouse cursor over the icon/button during that sleep it will actually work.

Not sure where to go from here.  Does that sound like normal behavior?

Between the events, move the mouse over the button using this http://www.vb-helper.com/howto_move_mouse.html and the move the mouse back, that'll probably work...

Have you tried using PostMessage instead of SendMessage?

Vinny I did try that with the same result.

Atan, that ClientToScreen api was exactly what I needed.  Here's what I have now (working).  Hopefully someone else finds this useful in a search.

Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Declare Function ClientToScreen Lib "user32" (ByVal hwnd As Long, lpPoint As POINTAPI) As Long

Const WM_LBUTTONDOWN = &H201
Const WM_LBUTTONUP = &H202
Const MK_LBUTTON = &H1

Dim p2 as POINTAPI

ClientToScreen pns, p2
SetCursorPos p2.x, p2.y
Call PostMessage(pns, WM_LBUTTONDOWN, MK_LBUTTON, 0)
Call PostMessage(pns, WM_LBUTTONUP, 0, 0)

pns is the hwnd of the aol button I want to click.  

Thanks everyone for the input!
