I'm trying to add a logo to our Outlook addin. It will look something like the pic below...
User added an image

The only problem is that it's not making the background transparent. Is there a way to do this using the Toolbar addin? I've tried using a picture box, a label, a button... but they all default to 'control gray' for the background color. I'm guessing it's getting that from the Toolbar container? Is there any way to add an image with a width > 16 and have the background be transparent so you can see the gradient color of the toolbar?

I'm using the latest version of Addin Express + Toolbar addin in VB.NET 2003.

Hi Jeff,

The current version of Toolbar Controls .NET doesn't allow to draw transparent images on the Office toolbars. We have plans to add such a feature in the future.
