I think the ability to use the ProgressBar object when programming in Inventor is great and simple. But it would be a great enhancement to be able to replace the default logo used in the ProgressBar object (see picture below) with the one you think is applicable to the situation the progress bar is used in, or with your company logo.
Like the Picture/Image-control in VBA you should be able to select which picture should be used, like:
Dim ProBar as Inventor.ProgressBar
Set ProBar = ThisApplication.CreateProgressBar(True, 100, "Progress")
ProBar.Picture = "C:\Logos\CompanyLogo.jpg"
Probar.UpdateProgress
