You can use the AddonName property of a MenuItem or ToolbarItem object to pass arguments to a function in a VBA project. This article provides some sample code that demonstrates how to do this.


Suppose you have a private function named MyAddon in the ThisDocument module of a VBA project:

Private Sub MyAddon(arg1 As Integer, arg2 As String)

To pass arguments to the MyAddon function, you could use the following line of code:

visToolbarItem.AddOnName = "ThisDocument.MyAddon 0, ""Test Button 1"" "

In this example, visToolbarItem is a ToolbarItem object. MyAddon is your private function. The values 0 and Test Button 1 are the arguments that will be passed to the MyAddon function. Note that the order of the arguments as well as their types must match the order and types in the function declaration.
