ThisWorkbook object and Workbook_Open Event

If you want to trigger any action at the startup of your workbook, you must add your code under Workbook_Open. The event must be added into the ThisWorkbook object of your workbook.

You can open the ThisWorkbook object by simply double-clicking on its name in the Project Explorer pane of the Visual Basic for Applications (VBA) window.

The code to show a welcome message

You have two options to show a welcome message: Either use a simple message box (MsgBox) or create your own form and call the form. The message box method is relatively easier to do compared to the form: All you need is a single line of code with your message.​

MsgBox "Thank you for using our workbook"

This line pops up a message box with an OK button.

Private Sub Workbook_Open()
    MsgBox "Thank you for using our workbook"
End Sub

Let's continue with a few customization options that you can apply to welcome message boxes.

Multiple lines

By default, a message box displays your message in a single line. If you want to see more lines in your message box, add the vbNewLine value into the text.

MsgBox "Thank you for using our workbook" & vbNewLine & ""

Dynamic values

You can also concatenate your welcome text with a value in your workbook to add a dynamic value. For example, the following example demonstrates displaying values in cell B4, along with the message itself.

MsgBox "Thank you for using our workbook. " & [B4]

Modifying message icon and title

The default message box doesn't contain any formatting or icons, and comes with the "Microsoft Excel" title. Each behavior can be altered by supplying the necessary arguments in the code.

The second argument of the MsgBox command determines what the message box includes, like buttons or icons. There are four (4) constant values for icons:

Constant Description
vbCritical Shows the critical message icon
vbQuestion Shows the question icon
vbExclamation Shows the warning message icon
vbInformation Shows the information icon

The following is an example for using an information icon.

MsgBox "Thank you for using our workbook.", vbInformation

The next argument is for the title. Enter a string value to alter the title of the message box.

If you want to change the title only, omit the second argument. Note that the repeating commas (, ,) indicate the second argument.

MsgBox "Thank you for using our workbook.", , "Welcome"
