Long story:
I made a tool which helps me work with my notebook until I get a replacement for some faulty keys. But there's an issue to make a screenshot of the active window in certain situations (seems that my keyboard hook routine gets blocked from certain programs), so I added an icon to the taskbar to be able to do the same functions like the keyboard shortcuts do.

Short problem description:
How to get the handle of the taskbar overflow? Otherwise I'll loose the handle of the 'real' active window.

Code: Select all

Procedure.s GetWinTitle(handle)

	Protected name.s
	Protected len

	name.s=Space(#MAX_PATH)
	len=GetWindowText_(handle,@name,#MAX_PATH)

	ProcedureReturn Left(name,len)

EndProcedure

MyWin=OpenWindow(0,0,0,100,100,"*")
MyBar=FindWindowEx_(#Null,#Null,"Shell_TrayWnd",#Null)
MyIco=AddSysTrayIcon(0,MyWin,LoadIcon_(#Null,#IDI_INFORMATION))

AddWindowTimer(0,0,100)
Repeat

	Dummy=GetForegroundWindow_()
	SetWindowTitle(0,Str(Dummy))
	If Dummy<>MyBar And Dummy<>MyWin And Dummy<>Active
		Active=Dummy
		Debug "New Active: "+Active+" = '"+GetWinTitle(Active)+"'"
	EndIf

Until WaitWindowEvent()=#PB_Event_CloseWindow

Hi,

did you already look at these approaches?

Unfortunately, none of them yields the expected result here on Windows 11, using PB 6.02 LTS (x64).
However, the codes might be helpful for you.

Thanks for the links, as you said the codes don't work anymore.
There's also a thread in the older forum from 2009 about scanning the last active window but also with no usable solution because the taskbar overflow just didn't exist at this time.

Hi Rashad,

your codes don't work here, mainly because I don't use an english version of Windows 11.

Your program does assign a handle to hOverflow but it's a different handle as the one connected to the arrow up symbol on the taskbar to show the tray symbols.
The two other handles will be zero.
