Here's an MSDN chat link with lot's of good info:
http://msdn.microsoft.com/chats/vstudio/vstudio_041602.asp

and

A Walkthrough on Multithreading:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcn7/html/vaconFreeThreadingExample.asp?frame=true

With forms applications you have to be careful with the form and controls.
You have to invoke any form/control methods only on the thread they were
created with, so read the documentation regarding the Control.Invoke and
Control.BeginInvoke methods. Good luck.

Thanks,

Sam

The key piece of code you need to do this (sorry it's in C#, but you will
get the idea):

private void control_Event(object sender, EventArgs e) {
if (InvokeRequired) {
Invoke(new EventHandler(control_Event), new object[] {sender, e});
} else {
// Do whatever here...
}
}
