I need to invoke the vb threading gods of the forum.  I'm very new to delegates and cross form method calls etc.

I have a main form with a class level WaitWindow that methods on the form can show, hide, update whatever.  This form makes several calls to a class that performs a lot of data manipulation.  Some of these take a long time, so I decided updating the WaitWindow would be nice to let the user know something is going on.

My declaration of the WaitWindow on the form.

Here is my method to Update that WaitWindow

And on my class that does the data manipulation, I added this delegate

And I added a Reference to the main Form to call UpdateWaitWindow on

Now should I be able to call this UpdateWaitWindow by simply ?

Well, that leaves me out, even though I do own a sewing machine and I'm not afraid to use it!



Sorry for the unhelpful reply...it's been a hard week, it's friday, I've been up way too long and it's summer time, and silliness just bubble to the fore.



I'll be watching the thread (er...no pun intended) to learn more about threads though!

Yes, that's how you would do it.  Now, when you're calling the Invoke of the ISynchronizeInvoke interface (on any Control object, like a form), you have to make sure that the control's thread is not busy.  Meaning, if you try to Invoke() from the main thread back to the main thread, you'll enter deadlock... the CLR waits until the main thread is not busy before calling the invoked method.

Great.  Thanks Ben.
