Clicking other application's buttons.

[Nitro]

Is this the way how to click the "OK" or any button from another application?

Thanks for helping!!!

Private Const WM_LBUTTONDOWN = &H201
Private Const WM_LBUTTONUP = &H202

Private Sub Timer1_Timer()
  Dim lng_Dialog As Long
  Dim lng_Button As Long
  lng_Dialog = Findwindow("#32770", vbNullString)
  lng_Button = FindWindowEx(lng_Dialog, 0&, "Button", vbNullString)
  Call Click(lng_Button)
End Sub

Sub Click(lng_Handle As Long)
  DoEvents
  
  Dim lng_Response As Long
  lng_Response = SendMessage(lng_Handle, WM_LBUTTONDOWN, 0, 0&)
  lng_Response = SendMessage(lng_Handle, WM_LBUTTONUP, 0, 0&)
End Sub

Probably, try it and see

I can see the button getting click but it is not closing the message box. The other way to close a message box is using the constant - wm_close. I just like to know why the code made the OK button click but it won't close the message box.

Nitro - did you ever find out why clicking the OK button did not fire the close event on the external applications message box???

I am also trying to click an external applications button and although I can see the button being clicked, the click event does not appear to be fired off. (Unfortunately, I cannot get away with using WM_CLOSE, becuase I need the event to take place.)

Any help would be greatly appreciated.

Sorry Ishamel!

I am still stuck and don't understand why. Someone out there have any ideas?

The codes above clicks a foreign application's button, but it doesn't do anthing afterward. We can actually see the "OK" button of the message box gets click.

Hi Nitro,

question:
Is the window the Active window when the button is clicked?

If not try to make it so and then retry.

Thanks Zaf!

It is actually a messagebox. I made it click OK but it won't close the message box. The other alternative is wm_close.

Thanks buddy.
