Hidden Button on Gui

[Chimaera]

Im trying to make a button that is hidden on a gui unless its my copy so i can check on work done by the other lads etc (and yes im in a position where i need to do that to keep an eye on stuff).

Anyway i set the button up like this

If FileExists( @ScriptDir & "\xtrabutton.dll") Then
    Local $ViewFolButton = GUICtrlCreateButton(" View Tech Edits ", 142, 475, 130, 30)
EndIf

So it has a hidden file on my pendrive that only i have  which has to exist for the button to show

All good so far, until i started adding a Case for the button

Case $ViewFolButton
            ShellExecute(@AppDataDir & "\SaveFolder")

Now the gui just flashes and dissapers when i have the Case in the script 

I cant find a way to allow the case statement when the button doesnt exist at the times when the hidden file doesnt exist

Any suggestions?

Just declare the variable first, and give it some arbitrary value.

Local $ViewFolButton = 45853997452

EDIT:

A value that will not conflict with an actual control.

before everything begins, declare $ViewFolButton and assign to it any meaningless value, like 9999 (or Dummy control i think will work also). then create it as you already do, but omit the Local keyword.

Something similar to what the others said.

I often do this when I have a MORE / LESS button on a GUI, for all controls that are on the expanded MORE GUI.

so

If FileExists( @ScriptDir & "\xtrabutton.dll") Then
     Local $ViewFolButton = GUICtrlCreateButton(" View Tech Edits ", 142, 475, 130, 30)
     $exist = 1
Else
     $exist = 2
EndIf

and then

Case $ViewFolButton And $exist = 1
            ShellExecute(@AppDataDir & "\SaveFolder"

'

'

P.S. What is happening with your current setup, is that that Case argument always runs (i.e. Case = "").

Or just create the button in all cases, but hide it if the file does not exist.

#include <GUIConstantsEx.au3>


$gui = GUICreate("GUI")
$Shownbutton = GUICtrlCreateButton("Shown", 10, 10)
$Hiddenbutton = GUICtrlCreateButton("Shown", 10, 40)

If FileExists(@ScriptDir & "\file.ext") Then
    GUICtrlSetState(-1, $GUI_SHOW)
Else
    GUICtrlSetState(-1, $GUI_HIDE)
EndIf

GUISetState()
Do
Until GUIGetMsg() = -3
