help please (buttons)

[benson]

Im new in using AutoIt and i have a small problem, how do i disable or gray-out a button when a condition is not met? for example, a listbox has a default value "Select item", if the value isnt changed, the button should be grayed out unless the listvalue is changed.

thanks

$Frm_Main = GUICreate("Test", 300, 250)
$Listbox = GUICtrlCreateListBox("", 20, 10, 100, 100)
$Button = GUICtrlCreateButton("Test", 40, 120, 60, 30)
GUICtrlSetState($button, 144)
GUICtrlSetData($ListBox, "Select Item|Item 1|Item 2", "Select Item")

While 1
   $Msg = GUIGetMsg()
   Switch $Msg
      Case -3
         Exit
      Case $ListBox
         If GUICtrlRead($ListBox) = "Select Item" Then
            If GUI CtrlGetState($Button) < 144 Then GUICtrlSetState($Button, 144)
         Else
            If GUICtrlGetState($Button) <> 80 Then GUICtrlSetState($Button, 80)
         EndIf
   EndSwitch
Wend

You could also do this

$Frm_Main = GUICreate("Test", 300, 250)
$Listbox = GUICtrlCreateListBox("", 20, 10, 100, 100)
$Button = GUICtrlCreateButton("Test", 40, 120, 60, 30)
GUICtrlSetState($button, 144)
GUICtrlSetData($ListBox, "Select Item|Item 1|Item 2", "Select Item")

While 1
   $Msg = GUIGetMsg()
   If GUICtrlRead($ListBox) = "Select Item" Then
      If GUI CtrlGetState($Button) < 144 Then GUICtrlSetState($Button, 144)
   Else
      If GUICtrlGetState($Button) <> 80 Then GUICtrlSetState($Button, 80)
   EndIf
   Switch $Msg
      Case -3
         Exit
   EndSwitch
Wend

$n1     = GUICtrlCreateList("", 10, 10, -1, 100)

$n2     = GUICtrlCreateButton("Read", 10, 130,100,25)
GUICtrlSetState (-1, $gui_disable)

GUISetState ()

Do
    $msg = GUIGetMsg()
    If GUICtrlRead ($n1) =  "item2" Then
        If BitAND(GUICtrlGetState($n2), $GUI_ENABLE) <> $GUI_ENABLE Then
            GUICtrlSetState($n2, $GUI_ENABLE)
        EndIf
    EndIf
    If GUICtrlRead ($n1) <>  "item2" Then
        If BitAND(GUICtrlGetState($n2), $GUI_DISABLE) <> $GUI_DISABLE Then
            GUICtrlSetState($n2, $GUI_DISABLE)
        EndIf
    EndIf   
Until $msg = $GUI_EVENT_CLOSE

I should have pointed out that I use the second method more for Inputs to make sure that a control stays disabled until a string has been entered into the input.

Thanks for the answers guys, they helped solve my problem, btw, i noticed "144" and "80" from the code below.

If GUICtrlRead($ListBox) = "Select Item" Then

If GUI CtrlGetState($Button) < 144 Then GUICtrlSetState($Button, 144)

Else

If GUICtrlGetState($Button) <> 80 Then GUICtrlSetState($Button, 80)

EndIf

What are they for?

Thanks

I use actual values instead of the GUI constants. Thats all. 144 = 128 + 16 (Disabled + visible) and 80 = 64 + 16 (Enabled + visible). I never use the constants but in particular when I am using GUICtrlGetState().

BTW: $GUI_EVENT_CLOSE = -3
