creating force focus child windows

[ryeguy]

I have a child window, and I want to make sure that the user can't click any buttons or even activate the parent window while the child window is up. I've seen this done, but I don't know what styles, if I can even do that here, to use. I've already tried $WS_EX_TOPMOST and most of the others but I can't seem to get it to work right.

Example:

expandcollapse popup

#include <GuiConstants.au3>

$main = GUICreate("MyGUI", 392, 322)

$Button_1 = GUICtrlCreateButton("Input", 140, 190, 70, 30)

GUISetState()
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
        Case $msg = $Button_1
            GUISetState(@SW_DISABLE, $main)
            _Input()
            GUISetState(@SW_ENABLE, $main)
            GUISetState(@SW_SHOW)
        Case Else
       ;;;
    EndSelect
WEnd
Exit

Func _Input()
    $popup = GUICreate("PopUP", 191, 85, -1, -1, $WS_DLGFRAME, $WS_EX_TOPMOST)
    
    $Input_1 = GUICtrlCreateInput("Input1", 0, 0, 180, 20)
    $Button_2 = GUICtrlCreateButton("OK", 60, 40, 60, 20)
    
    GUISetState()
    While 1
        $msg2 = GUIGetMsg()
        Select
            Case $msg2 = $Button_2
                ExitLoop
            Case Else
           ;;;
        EndSelect
    WEnd
    GUIDelete($popup)
EndFunc ;==>_Input
