To create an unavailable button

[Tripredacus]

I have searched the site (it is a tough thing to search for) and the help file does not tell me what I need.

I have an app that checks to see if a program is installed. If it is installed, it displays a button on the GUI. Clicking the button would open the program. At this time, the Else for its detection is to =1, thus it does not display. How can I make it so if the program is not found, then the button is shown as unavailable?

Here is the code, even though you shouldn't need it.

$QC_Label = GUICtrlCreateLabel("Applications Installed",320,50,120,20)
If FileExists("C:\Program Files\CyberLink\PowerDVD\PowerDVD.exe") Then
    $QC7 = GUICtrlCreateButton("PowerDVD",320,70,120,20)
Else
    $QC7 = 1
EndIf

Look up - GUICtrlSetState and $GUI_DISABLE in the help file

Yes, thank you, that worked well.
