If you are using VB.Net, which I imagine you are since you're asking about threads, you can marshal you call, using a delegate, onto the thread which created the GUI controls. I wrote a C# Tutorial on cross thread communication that you might find useful. Granted it's in C#, but the concept is the same for VB.Net. Are you using something other than VB6, say VB2005 or VB2008?
