MsgBox: Prompts a dialog Box that displays a message.

Examples:

MsgBox("Thank You for the Help!")

Parameters

Prompt

required. Stringexpression displayed as the message in the dialog Box. The maximum length of Promptis approximately 1024 characters,depending on the width of the characters used. If Promptconsists of more than one line,you can separate the lines using a carriage return character ( Chr(13 )),a lineFeed character ( Chr(10 )),or a carriage return/lineFeed character combination ( Chr(13 )& Chr(10 )) between each line.

Buttons

Optional. Numeric expression that is the sum of values specifying the number and type of buttons to display,the icon style to use,the identity of the default button,and the modality of the message Box. If you omit Buttons,the default value is zero.

Title

Optional. Stringexpression displayed in the title bar of the dialog Box. If you omit Title,the application name is placed in the title bar.

Settings

TheMsgBoxStyleenumeration values are listed in the following table.

The first group of values (0–5) 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; the fourth group (0,4096) determines the modality of the message Box,and the fifth group specifies whether or not the message Box window is the foreground window,along with the alignment and direction of the text. When adding numbers to create a final value for theButtonsargument,use only one number from each group.

Return Values

Exceptions/Errors

Remarks

If the dialog Box displays aCancelbutton,pressing the ESC key has the same effect as clickingCancel. If the dialog Box contains aHelpbutton,context-sensitive Help is provided for the dialog Box. However,no value is returned until one of the other buttons is clicked.

NoteTo specify more than the first argument,you must use the MsgBoxfunction in an expression. If you omit any positional arguments,you must retain the corresponding comma delimiter.

Example

This example uses theMsgBoxfunction to display a critical-error message in a dialog Box with Yes and No buttons. The No button is specified as the default response. This is done by combining theMsgBoxconstant values into one numeric expression. In this case,adding 4 (the Yes/No button combination) and 16 (the Critical Message window) and 256 (the second button as default button) gives a total of 276. The value returned by theMsgBoxfunction depends on the button chosen by the user: Yes returns a value of 6; No returns a value of 7.
