Just subtle point with the Windows7Task Progress bar...This took a while to work out, and I'm not sure it was mentioned in the article in the "How to use" section.The only way I got the control to actually update the TaskBar Icon button, was to pass it the applications mainform and not the form (Or it parents) that the control was embedded onto (Via sub usercontrols etc)
So (as a summary), in the form that hosts the Progress control, when setting the control use Application.OpenForms[0] (Or something similar to get the Application start form)
BTW, great time saver for .Net2 Apps
I'll be using it in http://frwingui.codeplex.com/documentation
