explain
If both the help file and the context are provided, the user can press F 1 to view the help topic corresponding to the context.
If the dialog box displays the Cancel button, pressing the ESC key has the same effect as clicking Cancel. If the dialog box contains a help button, the dialog box has context-sensitive help. However, no value will be returned until the other buttons are clicked.
When MicroSoft Internet Explorer uses the MsgBox function, the title of any dialog box always contains "VBScript" to distinguish it from the standard dialog box.
The following example demonstrates the use of the MsgBox function:
Dim MyVar
MyVar = MsgBox ("Hello World！" , 65, "MsgBox example")
MyVar contains 1 or 2, depending on which button is clicked.
