I cannot make any of these ControlSetText, ControlSend, WinGetHander to work with our C# developed forms. I am sure my syntax of them are correct because I make them work with the installation automation.
AutoIt help mentions that AutoIt might not work well with non-stand windows forms. Is that the reason? But the AutoIt v3 Window Info tool can see the Class, Instance, ClanssnameNN of the forms.
And these control functions don't even return anything, They just hang, never return.
