VBA MsgBox – How to use

In VBA, MsgBox function is used for displaying a dialog box with a predefined message. It returns an integer value based on the button clicked by the user, this helps to keep a track of the option selected by the user.

VBA Msgbox can be mainly used for the below three reasons:

1. For displaying a message to the End user.

2. For graceful termination of a program in case of any unexpected exception.

3. For deciding the program flow based on the user selection.

Syntax of MsgBox function in VBA:

The syntax of VBA Msgbox is as follows:

MsgBox (Text_String [, buttons] [, title] [, helpfile, context])

Here ‘Text_String’ is the message that you want the msgbox to display. The maximum length of ‘Text_String’ is 1024 characters.

‘buttons’ parameter specifies the type of buttons and icon that you want to be shown on the message box. It is an optional parameter. If you omit it then msgbox shows the default ‘vbOKOnly’ button.

‘title’ refers to the text displayed in the title bar of message box. This is an optional parameter.

‘helpfile’ is a string parameter that specifies the help file to be used for the dialog box. It is also an optional parameter but it becomes mandatory if ‘context’ parameter is to be used.

‘context’ is a numeric parameter that specifies the number assigned to the appropriate Help topic. It is an optional parameter but it becomes mandatory if ‘helpfile’ parameter is used.

Different values of ‘buttons’ parameter in Msgbox:

In VBA message box, ‘buttons’ parameter can have following values:

ConstantDescription
vbOKOnlyIt displays a single OK button
vbOKCancelIt displays two buttons OK and Cancel.
vbAbortRetryIgnoreIt displays three buttons Abort, Retry, and Ignore.
vbYesNoCancelIt displays three buttons Yes, No, and Cancel.
vbYesNoIt displays two buttons Yes and No.
vbRetryCancelIt displays two buttons Retry and Cancel.
vbCriticalIt displays a Critical Message icon.
vbQuestionIt displays a Query icon.
vbExclamationIt displays a Warning Message icon.
vbInformationIt displays an Information Message icon.
vbDefaultButton1First button is treated as default.
vbDefaultButton2Second button is treated as default.
vbDefaultButton3Third button is treated as default.
vbDefaultButton4Fourth button is treated as default.
vbApplicationModalThis suspends the current application till the user responds to the message box.
vbSystemModalThis suspends all the applications till the user responds to the message box.
vbMsgBoxHelpButtonThis adds a Help button to the message box.
VbMsgBoxSetForegroundEnsures that message box window is foreground.
vbMsgBoxRightThis sets the Text to right aligned
vbMsgBoxRtlReadingThis option specifies that text should appear as right-to-left.

 

Examples of Message boxes in VBA:

Now, let’s move on to some particle examples to understand the use of msgbox:

Example 1: Basic message box:

MsgBox Example-1

Sub Msg_exe()
MsgBox "This is a message!"
End Sub

Example 2: Message box with a title:

MsgBox Example-2

Sub Msg_exe()
MsgBox "This is a message!", , "This is the Title"
End Sub

Example 3:  Exclamation message box:

MsgBox Example-3

Sub Msg_exe()
MsgBox "This is a message!", vbExclamation, "This is the Title"
End Sub

Example 4: Message box with multiple lines

MsgBox Example-4

Sub Msg_exe()
MsgBox "Message Line 1" & vbCrLf & "Message Line 2", , "This is the Title"
End Sub

Note 1: Here ‘vbCrLf’ is the new line character in VBA. It can also be replaced by ‘vbNewLine’.

Example 5: Critical Message box with three buttons

MsgBox Example-5

Sub Msg_exe()
result = MsgBox("Critical Error Encountered", vbAbortRetryIgnore + vbCritical, "Error Encountered")
End Sub

Note 1:  Here I have used two values for the ‘button’ parameter separated by a ‘+’ sign.

Note 2: You will notice that here I have used a variable ‘result’ for accepting the value returned by Msgbox.

Values returned by MsgBox Function:

As I have foretold that VBA MsgBox function returns a value based on the user input. These values can be anyone of the below ones:

ValueDescription
1Specifies that OK button is clicked.
2Specifies that Cancel button is clicked.
3Specifies that Abort button is clicked.
4Specifies that Retry button is clicked.
5Specifies that Ignore button is clicked.
6Specifies that Yes button is clicked.
7Specifies that No button is clicked.

 

How you can decide program flow based on the values returned by Message Box?

In the above table you can see that VBA Msgbox function returns some integer values corresponding to button clicked on the dialog box. You can check this number using an IF Statement or by using a Select case statement.

In the below example I have done the same:

Sub Msg_exe()
Dim Ret_type As Integer
Dim strMsg As String
Dim strTitle As String
' Dialog Message
strMsg = "Click any one of the below buttons."
' Dialog's Title
strTitle = "Some Title"
'Display MessageBox
    Ret_type = MsgBox(strMsg, vbYesNoCancel + vbQuestion, strTitle)
' Check pressed button
Select Case Ret_type
Case 6
    MsgBox "You clicked 'YES' button."
Case 7
    MsgBox "You clicked 'NO' button."
Case 2
    MsgBox "You clicked 'CANCEL' button."
End Select
End Sub

So, this was all about the msgbox function in VBA. Do let me know if you have any queries related to the topic.
