I am only beginning to create an add-in so these questions may seem simple, but I can't seem to figure it out. My add-in consists of three buttons and a combobox. I would like the buttons to show a caption as well as the image. I can get this to occur with a button press or enabling an extenstion. However, I would like this to occur at startup. The combobox will be populated, but I can only get this to occur when I make a selection on the empty box. I would also like this to occur at startup. I've tried to use onCreate and onUpdate and neither work.
How can I get this to occur on startup? I am using .NET.
Currently I can only get the combobox to add items when selecting. What I want to do is to populate the combobox at the beginning before anything else.
