another error...

C:\Documents and Settings\JBRANCO\My Documents\Visual Studio Projects\thread test\Form1.vb(94): Method 'Public Function DownloadPic() As Object' does not have the same signature as delegate 'Delegate Sub ThreadStart()'.

[PT Exorcist]

ahhh..seems like i can only put in addressof **** sub's and not funcions...

The entrypoint for the thread must match the delegate definition used in the thread class's constructor:

<Serializable>
Public Delegate Sub ThreadStart()

This means the entrypoint must be parameterless and must be a sub. If you need parameters, you have to make properties for them, so you can first set the properties, and then start the thread with a parameterless sub. You can then use the properties instead of the missing parameters.

Editted: It would not make any sense to start a thread at a function.
You would have to wait to get the return value, so the benefit of a seperate thread would be vanished.

Just a note, you can just have your method raise an event when it is done. Then pass in as arguements the value(s) you want to return.
