Question about the Message Box

Hi,
Just wondering, I know that there is a way so that when a message box comes up the user can do nothing else till he/she clicks on one of the buttons on the message box.

I was just wondering if any one knows how to do it, I had some example code once but I am not sure where it has gone, I tried looking for it but could not find it.

If anyone knows about it and could help me please reply.

Thanks

MsgBox "help me", vbOKOnly, "Help"

Ok,
That will bring up a message box which is all good, but the user can just click on another program in the background and continue working as if the message box was not there.

I remember that They called it a System wide message box or something like that, which means that nothing will be done till a button is pressed on the message box, kinda like the Ctrl + Alt + Del thing, when that box is up nothing will work till the Cancel button or shutdown button or end task button is pressed.

Thanks for any other help
