MsgBox function

MsgBox( msg, [type] [, title] )

Displays a message in a dialog box and waits for the user to choose a button.

msg: The string displayed in the dialog box as the message.
type: Optional parameter. Designates the type of button.
title: Optional parameter. Designates the dialog box title. If you omit the argument title, MsgBox has no default title.

The MsgBox function returns a value indicating which button the user has selected. The MsgBox statement does not.

Value	Meaning
0	Display OK button only.
1	Display OK and Cancel buttons.
2	Display Abort, Retry, and Ignore buttons.
3	Display Yes, No, and Cancel buttons.
4	Display Yes and No buttons.
5	Display Retry and Cancel buttons.

16	Stop Icon
32	Question Icon
48	Exclamation Icon
64	Information Icon

0	First button is default.
256	Second button is default.
512	Third button is default.
768	Fourth button is default
0	Application modal
4096	System modal

The first group of values (1-5) describes the number and type of buttons displayed in the dialog box; the second group (16, 32, 48, 64) describes the icon style; the third group (0, 256, 512) determines which button is the default; and the fourth group (0, 4096) determines the modality of the message box. When adding numbers to create a final value for the argument type, use only one number from each group. If omitted, the default value for type is 0.

The value returned by the MsgBox function indicates which button has been selected, as shown below:

Value	Meaning
1	OK button selected.
2	Cancel button selected.
3	Abort button selected.
4	Retry button selected.
5	Ignore button selected.
6	Yes button selected.
7	No button selected.

If the dialog box displays a Cancel button, pressing the Esc key has the same effect as choosing Cancel.

Msg = "Do you want to continue ?"   ' Define message
'Style = vbYesNo + vbCritical + vbDefaultButton2   ' Define buttons
Style = 4 + 16 + 256   ' Define buttons.
Title = "MsgBox Demonstration"   ' Define title
Help = "DEMO.HLP"   ' Define Help file
Ctxt = 1000    ' Define topic
   ' context. 
   ' Display message.
Response = MsgBox(Msg, Style, Title, Help, Ctxt)
If Response = vbYes Then   ' User chose Yes
   MyString = "Yes"   ' Perform some action
Else     ' User chose No.
   MyString = "No"   ' Perform some action
End If
