GUICtrlSetTip and WinExists

[saywell]

I've just wasted hours trying to sort out a problem with my script.

I have a function that opens our patient admin system (PAS) if it's not already running (Winexists ("PAS") [using titlematch mode 2].

It worked fine when called from various places in the GUI, except for one.

After much faffle, I discovered that the tooltip was giving a false positive to the Winexists command! Strangely, it was the 'PAS' in the tip TEXT that did this' not in the tip title!

Solved by changing 'PAS' in tooltip text to 'P.A.S.'

I thought this might be helpful to others, so posting here as it's not mentioned in the helpfile.

Here's an example - different tooltip message on each button:

#include <GUIConstantsEx.au3>

Opt('MustDeclareVars', 1)
Opt ('WinTitleMatchMode', 2)
Example()

Func Example()
    Local $Button_1, $Button_2, $msg
    GUICreate("My GUI Button") ; will create a dialog box that when displayed is centered

    Opt("GUICoordMode", 2)
    $Button_1 = GUICtrlCreateButton("Run Notepad", 10, 30, 100)
    GUICtrlSetTip ($Button_1, "Opens Notepad if not already running", "Opens Notepad")
    
    $Button_2 = GUICtrlCreateButton("Run Notepad", 0, -1)
    GUICtrlSetTip ($Button_2, "Opens Bill's text editor if not already running", "Opens Notepad")
    GUISetState()      ; will display an  dialog box with 2 button

    ; Run the GUI until the dialog is closed
    While 1
        $msg = GUIGetMsg()
        Select
            Case $msg = $GUI_EVENT_CLOSE
                ExitLoop
            Case $msg = $Button_1
                If Not WinExists ("Notepad") Then
                Run('Notepad.exe')    ; Will Run/Open Notepad
                EndIf
            Case $msg = $Button_2
                If Not WinExists ("Notepad") Then
                Run('Notepad.exe')    ; Will Run/Open Notepad
                EndIf
        EndSelect
    WEnd
EndFunc   ;==>Example

Nice investigation.

Btw. is this in the end now a "feature" or "bug" of Autoit?

I guess referring to Winexists I expected tooltips not as a window, but on the other hand it may be nice to use this "feature" to trigger something when a certain tooltip pops up.

So is it worth to add a line to the documentation about this, either on Winexists or GUICtrlSetTip? Something like:"Remark: matching tooltips text returns true"

(I checked the docu and the bugtracker but did not find a trace of an issue related to this find.)
