C#/.NET - How to trigger update of listview from another thread

Question

It seems I'm forbidden to access (i.e. update) my list view control from another thread than the main thread.

How can I perform some threaded task and then signal somehow to start the update of the listview?

You need to call Invoke() to make the change.

The reason why is explained here: http://blogs.msdn.com/davidklinems/archive/2006/03/09/548235.aspx

How to do it with an example is shown here: http://msdn.microsoft.com/en-us/library/ms171728%28VS.80%29.aspx

Basically the changes have to be done from the main thread, so you have to get back on that to do your update.
