ControlGetHandle not matching on regex?

[cag8f]

Hi all.  I'm having issues understanding a regular expression when used with ControlGetHandle.  If I call ControlGetHandle and pass it a string value for the third parameter, it returns a valid ID (0x00150BE8).  But if I change that parameter from a string to a regular expression that I think should match, the function returns an invalid ID and an error code 1.  What am I misunderstanding?

My code is below.

$cWnd = WinWait("ShareX - Color picker", "", 3)
ControlClick($cWnd, '', ControlGetHandle($cWnd, "", 'WindowsForms10.BUTTON.app.0.1a52015_r6_ad14'))
ControlGetHandle($cWnd, "", 'WindowsForms10.BUTTON.app.0.1a52015_r6_ad142'); Returns: 0x00150BE8
;~ ControlGetHandle($cWnd, "", '[REGEXPCLASS:^WindowsForms10\.BUTTON\.app\.0\.1a52015_r6_ad142$]'); Returns: 0x00000000 (error code 1)

couldn't find which button that is the WindowsForms10.BUTTON.app.0.1a52015_r6_ad142
but i made an example with the button pick color from screen

$hWnd = WinWait("ShareX - Color picker", "", 3)
ConsoleWrite("$hWnd=" & $hWnd & @CRLF)

;pick color from screen
$hPickColorFromScreen = ControlGetHandle($hWnd, "", '[REGEXPCLASS:WindowsForms10\.BUTTON\.app\.0\..+_r\d+_ad1; INSTANCE:36]')
ConsoleWrite("$hPickColorFromScreen=" & $hPickColorFromScreen & @CRLF)
ControlClick($hWnd, '', $hPickColorFromScreen)

ControlGetHandle($hWnd, "", "[REGEXPCLASS:<>; INSTANCE:<>]")

REGEXPCLASS uses CLASS not CLASSNN !  See @ioa747 example.

@ioa747 @Nine Thanks for that.  Using CLASS instead of CLASSNAMENN, and adding the INSTANCE, resolved my issue. Thanks very much.  But what about the value for instance?  In my case it is `42` which I've hardcoded.  What if that changes in the future?  Can I use a regex pattern to match on it in my code?  Or maybe it is something that shouldn't change very often?

If you do not need the instance, just drop it.  It is not necessary to add INSTANCE with regex pattern.

It looks like I need to add the INSTANCE in this case.  If I remove it, ControlGetHandle still returns the correct handle ID. But the click from ControlClick doesn't seem to occur 😕

@Nine how can catch   with regex pattern, e.g. one click on the control

0x001D0E6A WindowsForms10.BUTTON.app.0.1a52015 _r22_ad1      20        1904234

so as not to catch any of the rest, without the use of INSTANCE ?

 

$hWnd = WinWait("ShareX - Color picker", "", 3)
ConsoleWrite("$hWnd=" & $hWnd & @CRLF)

;pick color from screen    WindowsForms10.BUTTON.app.0.1a52015 _r22_ad1
$hPickColorFromScreen = ControlGetHandle($hWnd, "", '[REGEXPCLASS:WindowsForms10\.BUTTON\.app\.0\..+_r\d+_ad1; INSTANCE:20]')
ConsoleWrite("$hPickColorFromScreen=" & $hPickColorFromScreen & @CRLF)
ControlClick($hWnd, '', $hPickColorFromScreen)

 

Edit:
or this is a  need case ?
