Mouse Click Event in VBA

Supriyo Dasgupta asked if there is a mouse event handler in VBA. He wants a value inserted in a cell when that cell is clicked on.

The standard way to do this is with the SelectionChange event. Every time the selection changes in the worksheet, the event is triggered. The event doesn't just trigger when a cell is clicked on, but also if someone presses a cursor control key that results in a different cell being selected.

As an example, let's say that you wanted cell B5 to contain the value 10 whenever that cell is selected. To implement that, you could use the following:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    If Not Intersect(Target, Range("B5")) Is Nothing Then _
      Range("B5").Value = 10
End Sub

This code is added to one of the sheet objects in the Project Explorer area of the VB Editor. Double-click the worksheet you want the event handler to apply to, and then add the macro to the resulting code window.

When the SelectionChange event is triggered, the target (the cell range being selected) is passed to the handler. The macro then checks to see if the target range contains cell B5, and if it does, stuffs the value 10 into cell B5. If you want to make sure that the macro only stuffs information into B5 if only B5 (the single cell) is selected, you can use this version of the macro:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    If Target.Address = Range("B5").Address Then _
      Range("B5").Value = 10
End Sub
