Unable to find control

Question

I want to find and click a button using Autoit. I tried AutoIt Window Information Tool but the button is not recognized so ControlClick() fails.

The button is active on the current window but Send("Enter") does not work. Tried using MouseClick() but the window does not appear in the same place every time, and I tried this script:

$hWnd = WinWait("vcredist_x86")
WinWaitActive("vcredist_x86")
ControlClick($hWnd, "", "[CLASS FROM AUTOITINFO]", "Left", 1)

but neither of them works. Is there any other way to identify and click the button?

Answer 1

When AutoIt Window Information Tool failed me I had success using the text property of the button/ui control:

ControlClick($hwin, '', '[CLASS:Button; TEXT:Cancel]')

Experiment with "&" in front of one of the characters (underlined by Windows to indicate an Alt + key shortcut), so try "&Cancel" instead of "Cancel". If that fails try ControlFocus() first:

ControlFocus($hwin, '', '[CLASS:Button; TEXT:Cancel]')
ControlClick($hwin, '', '[CLASS:Button; TEXT:Cancel]')

Inspecting .exe files for GUI resources (using Resource Hacker for example) may expose text/properties of a control. Example:
