WinHide does not hide win 10

[StanleyH]

Code: Select all

DetectHiddenWindows, on
SetTitleMatchMode, 2
winhide, Calculator
sleep, 7200
winshow, Calculator 

For some odd reason notice that the icon remains in the taskbar. What are some of your solutions to resolve this?

[jeeswg]

- Perhaps try the example here. It accepts an hWnd for the active window or any other window.
DllCall
https://autohotkey.com/docs/commands/DllCall.htm

Code: Select all

Example: Temporarily remove the active window from the taskbar by using COM.

- Although you probably know this, I'd just point out that pinned items always leave an icon in the taskbar.

- [EDIT:] Here's another approach, temporarily changing the window parent.

Code: Select all

q:: ;temporarily change window parent
WinGet, hWnd, ID, A
hWndParent := A_ScriptHwnd
hWndParentOld := DllCall("user32\SetParent", Ptr,hWnd, Ptr,hWndParent, Ptr)
Sleep, 3000
DllCall("user32\SetParent", Ptr,hWnd, Ptr,hWndParentOld, Ptr)
return

;doesn't work: doesn't restore taskbar button
;w:: ;temporarily change window owner
WinGet, hWnd, ID, A
hWndOwner := A_ScriptHwnd
hWndOwnerOld := DllCall("user32\SetWindowLong" (A_PtrSize=8?"Ptr":""), Ptr,hWnd, Int,-8, Ptr,hWndOwner, Ptr) ;GWL_HWNDPARENT := -8
Sleep, 3000
DllCall("user32\SetWindowLong" (A_PtrSize=8?"Ptr":""), Ptr,hWnd, Int,-8, Ptr,hWndOwnerOld, Ptr) ;GWL_HWNDPARENT := -8
return

- Btw your thread might be found by more people, if you changed the title to something like: 'WinHide does not hide taskbar button (Windows 10)'. Although maybe you can't change this, since you were NLI (not logged in).

the code you provided works on regular windows (notepad etc) but not on windows 10 apps windows like calculator or skype, there must be a method

Code: Select all

q:: ;temporarily change window parent
WinGet, hWnd, ID, A
hWndParent := A_ScriptHwnd
hWndParentOld := DllCall("user32\SetParent", Ptr,hWnd, Ptr,hWndParent, Ptr)
Sleep, 3000
DllCall("user32\SetParent", Ptr,hWnd, Ptr,hWndParentOld, Ptr)
return

- And the DllCall example, does that work?
- Also, try running the script as admin, just in case.
- Also, you are saying that WinHide does hide the windows, but that it doesn't hide the taskbar buttons. It at least hides the windows?

yes, winhide works, just leaves behind the taskbar icon, something that makes no sense

I even tried winhide, ahk_class ApplicationFrameWindow, Calculator

it does not work on win 10 calculator or skype etc (windows apps) it works on other things like notepad it works so good that the notepad task-bar icon seems to not be gone permanently lol, ill have to reboot.

[jeeswg]

Omg, always test on 'Untitled - Notepad'. Check for processes listed in Task Manager. Use WinShow to show windows. Use something like this to list windows, to avoid having to reboot:

Code: Select all

DetectHiddenWindows, On
;WinGet, vWinList, List ;all windows
WinGet, vWinList, List, ahk_class Notepad
vOutput := ""
Loop, % vWinList
{
	hWnd := vWinList%A_Index%
	WinGetTitle, vWinTitle, % "ahk_id " hWnd
	;WinGetClass, vWinClass, % "ahk_id " hWnd
	;WinGet, vPID, PID, % "ahk_id " hWnd
	vOutput .= hWnd " " vWinTitle "`r`n"
}
MsgBox, % vOutput

Topic is solved and yet the script doesn't work or am I missing something? I run the script with calculator active and it doesn't do anything.
