Hi, I just wanted to know what if the best pratice for the main render loop ? Is it better to call the peekmessage win32 function directly into the main render loop ?

Hey -- aren't ya going to answer the question? I mean, its one thing to point out that the examples suck, but, you could at least point people in the right direction... what is a better way to handle that loop?

Maybe use the paint events to render, or setup a timer?

Hi Tom,

This is very true in a background thread, but what if you have a single-threaded application that you want to keep responsive while you're inside your loop... with Sleep() calls, the app will just appear frozen.

I'm not clear why DoEvents would allocate memory... is it really DoEvents allocating the memory, or is it the code that gets an opportunity to run due to the call to DoEvents (ie: the message pump gets processed) that is doing this?

Hey Tom, it would have been helpful if you mentioned this in your book "Managed DirectX 9 Graphics and Game Programming" as it sent up major red flags in my C++/MFC trained mind! Invalidating in an OnPaint runs counter to everything I've learned! :-)

I have heard people comment on using the OnIdle for rendering as opposed to DoEvents or OnPaint. Any opinion on that?

I just noticed that the Aplication.DoEvents method was alocating memory. It seems strange that this would happen because in the Microsoft DirectX tutorials, this is what they use. I read somewhere that this may evetually get cleaned up automatically by .NET when resources get low, but I haven't tested it as I have 1gig ram.

I've tried running a render loop with the Application.Idle event, but that's no good because it is only fired once just before the app is about to go into the idle state, then it just sits there while idle.

I may try using a timer to call the loop or see if I can work out how to do a custom event that fires continuously whenever the application is in the idle state, otherwise I'll just stick with Application.DoEvents and blame Microsoft for the extraneous memory use.
