UI Automation, wait for element to be visible.

[LisHawj]

Is there a function in UI Automation that I can use to pause a script until an element is loaded or becomes visible before proceeding with the rest of the code?  We have thousands of computers and some of them are not the latest and greatest so it takes anywhere from an extra 15 seconds to as high as 120 seconds before the next element/control becomes visible on some devices.  This is wreaking havoc on my newbie brain.  I have included the part of the code that I need help with below.  Any insights and advices are much appreciated.

Hmmm...Just found UIA_Winwinwaitactive(), testing....

You can always wrap it in a loop with a Sleep call 

;~ Local $iCount = 0

; While we haven't found the next button
While Not IsObj($oButton4)
    ; Search for it
    $oDesktop.FindFirst( $TreeScope_Descendants, $pCondition5, $pButton4 )
    ; Attempt to create the object
    $oButton4 = ObjCreateInterface( $pButton4, $sIID_IUIAutomationElement, $dtag_IUIAutomationElement )
    ; If we found it (it's an object)
    If IsObj( $oButton4 ) Then
        ConsoleWrite( "$oButton4 OK" & @CRLF)
    Else
        ; Wait a little before retrying so we don't kill the old computers
        Sleep(500)
        
        ; Optionally, count the number of times this happens...
        ;~ $iCount += 1
        ; If it loops too many times, return an error
        ;~ If $iCount >= 10 Then Return SetError(1, 0, False)
    EndIf
WEnd

Edit: And this works for finding a lot of things... I made this into a function to wait for elements/windows/etc to appear, cause I got bored...

@seadoggie01 - I wished I am as proficient as most of the members of this forum.  Your gift above worked beautifully for me.  Thank you so very much.

Not really proficient... bored and lazy. There's a Bill Gates quote for lazy people... but I'm too lazy to find it

Why do you want something to run gui on thousands of computers? That sounds like there should be a better solution then gui interactively.
