Thank you for responding, however when I opened the project, the mouse over on each item didn't work. I looked at your code and I didn't see anywhere that this would happen. Under the sub ComboBox1_MouseHover I changed the code to Me.ToolTip1.SetToolTip(Me.ComboBox1, "hello") to see what it would do, it just gives a tool tip for the combo box, not each item. The way you had it, didn't even give a tooltip for the combo box. Is it possible to set a different tooltip for each item, I need to be able to put acronyms in the combo box, and have a tool tip give the full meaning.
Thank you for all your efforts
