Project #6: Adding VBA Code to the ComboBox Change Event

To add VBA code to the Change event of a ComboBox in Excel VBA, follow these steps:

Open the Visual Basic Editor (VBE): Press Alt + F11 in Excel to open the VBE.

Open the User Form: Double-click on the User Form object in the Project Explorer window to open the User Form in design view.

Access the Code Window: Right-click on the ComboBox control on the User Form and select "View Code" from the context menu. This will open the code window for the ComboBox control.

Select the Change Event: In the code window, you'll see two drop-down menus at the top. From the left drop-down menu, select the name of the ComboBox control. From the right drop-down menu, select "Change". This will create a new subroutine for the Change event of the ComboBox.

Write VBA Code: Write your VBA code inside the subroutine for the Change event. This code will run automatically when the selected item in the ComboBox changes.

Test the User Form: Close the VBE and return to Excel. Press Alt + F8 to open the "Run Macro" dialog, select the User Form's Initialize event (usually named UserForm_Initialize), and click Run. This will display the User Form. Interact with the ComboBox to trigger the Change event and execute the code.

Here's an example of how you can write VBA code for the Change event of a ComboBox:

Private Sub ComboBox1_Change() 
' Display a message box with the selected item 
MsgBox "Selected item: " & ComboBox1.Value 
End Sub

In this example, when the selected item in ComboBox1 changes, a message box is displayed showing the selected item's value. You can customize this code to perform any action based on the selected item in the ComboBox.
