Have you tried if application.doevents works for you? I've never used it in vb.net, but in vba it would do what you expect.

Look at the documentation here : http://msdn.microsoft.com/en-us/library/system.windows.forms.application.doevents(v=vs.110).aspx

Not sure it's "best pactices" though.

You're better off use threads and the "backgroundworker". See if this http://msdn.microsoft.com/en-us/library/vstudio/system.componentmodel.backgroundworker works for you and let us now.

Good luck.

In the last week or so I posted a new tutorial on creating and managing background threads. You can find it here.
