I have an addin toolbar where I would like to change the button graphics for one of the buttons on the fly at runtime.

I also have a timer that is fired to check for some state and if that state becomes true I want to change the button graphics for one of the toolbar buttons to a different bitmap to indicate this state.

Is this possible?

I am aware of ShowBubbleTooltip() but I don't want to keep showing this each time the timer fires.

What I'm looking for is like a 'badge' or 'glyph' to add to a toolbar button to indicate a condition or state to the user.

I'm currently creating the toolbar via:  CreateCommandGroup2, AddCommandItem2 and  "...LargeIconList = iBmp.CreateFileFromResourceBitmap..."

Thanks for your help!
