what this ClassName Means?

Question

Hi, I'm trying to build GUIA program using python 3 without using pywinauto and autoit

The target program is composed by many Edits, RadioButtons, Buttons etc
ClassName of Edit is returned as "WindowsForms10.EDIT.app.0.13965fa_r9_ad1"
It goes well when I want to do "SetText" by "SendMessage" to Edit control. Like "Edit" in notepad,
win32con.WM_SETTEXT is suitable for Msg in SendMessage()
But RadioButton(in fact RadioGroup) and Buttons have strange ClassName
"WindowsForms10.Window.8.app.0.13965fa_r9_ad1"
And problem is here.
I'm trying to click specific Button so do SendMessage(button_hwnd, Msg, 0,0)
At first, Msg is BM_CLICK, NM_CLICK. But it dosen't work.
Afterwards I did iteration.
for i in range(-5000, 5000):
SendMessage(button_hwnd, i, 0,0)
but doesn't work.
It is same when did PostMessage
Please let me know when it returns a ClassName like this and how I get to click the Button.



Answer 1

Class name "WindowsForms10.Window.8.***" seems not a standard control's class name and it is undocumented. You may want to consult the developer or supplier of the target program for how to access this control.

UI automation seems a possible solution for you (If this control supports). For how to invoke a button through UI automation you can refer to "Invoke a Control Using UI Automation". Hope this document will guide you find a solution in Python.

I dont find what the classname means, but how to operate button!
WM_LBUTTONDOWN AND
WM_LBUTTONUP

I realize that except special windows like treeview, WM is well work!

Answer 3

Class names like "WindowsForms10.EDIT.app.0.13965fa_r9_ad1" are generated by .NET in Winforms (C#, VB.NET)
But to simulate actions, it is better with UI Automation (use Inspect tool from Windows SDK to check and identify controls)
