Hadnling windows messages when in big loop

[Fred Flintstone]

I have a project, that loops through a lot of wmi queries, and while its
looping, the window will not repaint, I can't move or size the window.
I remember having a similar problem back in an excel macro, and I ran a
command that told the application to process windows messages.
Is there such a thing in vb.net, or is there a way to make sure windows
messages get processed in big cpu greedy loops?

Also, Is it a big deal to make code multy threaded? Where should a person
start looking for info regarding multitreaded programming in vb.net?

In your loop you can call: Application.DoEvents()

Hey Fred,

My first answer will help with repainting but not with moving the window.
Sorry I missed that requirement on my first read.

Any easy way to use threading is to get started with asynchronous delegates.

Here is a good article:

Once you create a Delegate through which to call the method with your big
loop, repainting, moving, and other user interface actions will work while
the big loop is processing your wmi queries.

Thanks, that was just the sort of answer I was looking for.
