Create vbscript messagebox that stays on top and blocks other windows

Question

Help me please to create a messagebox which stays always on top, and user can't use other windows functions like calling start menu or interacting with other windows until he presses the OK button on messagebox.

Solution

The second parameter of the MsgBox function allows you to specify options for the dialog.

MsgBox "Hello, World!", vbSystemModal
