How to get a true MsgBox modal mode ?

Recommended Posts



I have an AutoIt application, with a main interface consisting of several controls (buttons, lists...).

At some point, it displays a MsgBox, something like :

MsgBox(4096+48, "Warning", "Click OK if you want to go on with the application")

I'm looking for a way to make the click on this MsgBox mandatory before any other action can be made on the application.

For now, the 4096 flag keeps my MsgBox on top, but I can still put it aside and click on the controls of my main interface behind : nothing will happen on the moment, but once I click OK on the MsgBox, my previous actions on the interface will somehow "debuff" and take action. And this is precisely what I want to avoid. I want any action on the main interface to be simply IGNORED as long as the MsgBox is up.

If I'm not mistaken, what I'm trying to get is a real modal behaviour (as described in http://en.wikipedia.org/wiki/Modal_window) and it seems AutoIt "modal" flag isn't completely modal... :huh:

Any thoughts or ideas ?

Use the parent window parameter of MsgBox, and set the parent to the GUI for the application.

And you want it to be application modal, rather than system modal, so remove the 4096 flag.

#include <Constants.au3>
#include <GUIConstantsEx.au3>

Local $hGUI = GUICreate("Test")


MsgBox($MB_APPLMODAL, "MsgBox", "Hello, World!", 0, $hGUI)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE

Faalamva (and others),

Reading the Modal MsgBox Styles tutorial in the Wiki might be helpful. ;)
