Excel VBA Message Box
As there are two things in this word one is VBA and other is Message Box. In this, I’ll be explaining how to use Message Box function using VBA (Visual Basic for Applications).
VBA – It’s a programming language for those who work in Excel and other Office programs, so one can automate tasks in Excel by writing so-called Macros.
Message Box – As the name suggests it is nothing but a dialog box which is used to notify the user about something or giving some information, showing a custom message with some custom buttons like Yes/No or Cancel/Ok.
Message Box has various parts:
Title – It will display the Title of the Message box i.e. what the message box is about. By default, it will show the name of the application “Microsoft Excel” because we are opening it in Excel.
Prompt – It shows the message that we want to display in the dialog box.
Button – We can add and customize different buttons in the message box. Buttons we can add like Cancel, Ignore, Abort, Ok, Retry, etc. OK is a default button which is displayed.

Close Icon – It has a red color close icon from where we can directly switch off the Message Box.
As we know that MsgBox is a function in VBA like other functions it also has syntax and arguments to be passed in it.
MsgBox( prompt [, buttons ] [, title ] [, helpfile, context ] )
Syntax of VBA Message Box in Excel
The syntax for VBA Message Box is as follows:
Prompt – As we have discussed earlier that Prompt is a required argument. It displays the message that we see in the MsgBox. Our example text is “ This is Message Box Demo…” is the Prompt. We can use 1024 characters in a prompt and can also be used to display the values of the variables.
Buttons – It displays the buttons in the box. Suppose if I use vbOKCancel it will display both OK and Cancel button, and if I use vbOKOnly it will display only OK button.
Helpfile – It opens the help file when the user clicks on the Help button. The Help button will only appear if we write the code for it. We also need to specify the context arguments, while using helpfile.
Button Constants in MsgBox
In this section we are going to cover the different buttons used in the Message Box:-
- vbOKOnly – This only shows OK button.
- vbOKCancel – This shows OK and Cancel button.
- vbYesNo – This shows Yes/ No buttons.
- vbYesNoCancel – This shows Yes, No, and Cancel buttons.
- vbAbortRetryIgnore – This shows Abort, Retry and Ignore Buttons.
- vbRetryCancel – This shows Retry and Cancel button.
- vbMsgBoxHelpButton – This shows the Help button.
Now we will see how the Message Box is created in the VBA.
To enable Macro’s in Excel you have to first enable the Developers Tab and then change the settings through which Macro’s run.
