Get window class from the handle?

4 posts in this topic

#1 ·  Posted (edited)

Hey Guys,

I saw this bit of code on a different website recently and am trying to do something slightly different with it.

$vMousePos = MouseGetPos()
$vWin = DllCall("user32.dll", "hwnd", "WindowFromPoint", "int", $vMousePos[0], "int", $vMousePos[1])

If you run the above code, you'll get two variables being the handle and then the title.

From the handle only (Because there are multiple windows open with the same title) I want to be able to retrieve the class, this will enable me to to do a simple:

If $vClass = "TextExampleHere" Then
    ;WinActivate("[CLASS:" & $vClass & "]")
    WinActivate($vClass) ; Unsure what ones correct...
EndIf

Any ideas?

Hyflex,

A search of the Help file for "handle to classname" brought up _WinAPI_GetClassName which seems to be just what you require. :)

As to syntax, you would need:

WinActivate("[CLASS:" & $vClass & "]")
once you have the classname. But why not use the handle directly? ;)

Hi Melba23,

I had a search but I didn't search for that phrase, if you saw my browser history too it's full of hundreds of google and autoit searchs :P but yes that seems to be what I need.

Well, it's possible for the window the mouse is hovering over isn't the intended window and the only way I can do a check is by comparing the classname because some days the windows might be called "Window 1", "Window 1" and "Window 1" but other days they might be "Window", "Window 5", "Window 10" and using the WinTitleMatchMode option doesn't quite cover it enough.

Classname comparison is the best option for me.

Thanks M23

Hyflex,

My comment was related to the use of the classname in the WinActivate code - once you have identified the correct window by classname you can simply use its handle to activate it. :)
