Refresh a Window

How I refresh - for example a combo box - in a window, after I do an operation in another window ?

I know that I can close and re-open, but does not make sense to me …

It depends on what you mean by “refresh.” If you want to modify the contents of the list, you can use the AddRow, RemoveRow, InsertRow, and DeleteAllRows methods just like you would with a ListBox.

e.g.

Window1.ComboBox1.RemoveRow(0) ' remove the first row Window1.ComboBox1.InsertRow(0, "New First Row")
