Using a handle instead of id to interact with a control.

[gottygolly]

I wasn't sure how to search for this but I did try and couldn't find anything.

In my script I have a for loop create a bunch of labels and through this I was wanting to be able to click on any label and call the function "_Click" so that I can change the color of the box accordingly.

I originally started using @‌gui_ctrlid to get the id of the label but I realized that once I started adding more code it would mess with getting the correct id. I thought I could use the macro @gui_ctrlhandle but I'm not sure on how to interact with the control through this (normally I would use the ControlId)

The code below should hopefully help you understand if you are confused.

Func _Click()
   $id = @GUI_CtrlHandle
   GUICtrlSetBkColor($id,$color)
EndFunc

Thanks for any help and if you need additional information please let me know so I can aid you in aiding me.

I do not see why it should - ControlIDs to not vary unless you delete and recreate the associated control. This works just fine:

#include <GUIConstantsEx.au3>

Opt("GUIOnEventMode", 1)

$hGUI = GUICreate("Test", 500, 500)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")

For $i = 0 To 9
    GUICtrlCreateLabel("", 10, 10 + (30 * $i), 200, 20)
    GUICtrlSetBkColor(-1, 0xCCFFCC)
    GUICtrlSetOnEvent(-1, "_Click")
Next

GUISetState()

While 1
    Sleep(10)
WEnd



Func _Click()
    $cCID = @GUI_CtrlId

    GUICtrlSetBkColor($cCID, 0xFFCCCC)
EndFunc



Func _Exit()
    Exit
EndFunc

I realized that the function that I posted I had modified and I modified it to work properly, in my script instead of having this:

Func _Click()
   $id = @GUI_CtrlId

   GUICtrlSetBkColor($id,$color)
EndFunc

I had this:

Func _Click()
   $id = @GUI_CtrlId

   GUICtrlSetBkColor($label[$id],$color)
EndFunc

A simple mistake but thank you for the help melba, I compared your example code to my script and found the error that way.

Appreciate it!
