DirectDraw VB C++ *Resolved*

[Nafreya]

I have been working on a game for some time now in C++ using DirectDraw, for reasons i changed to VB still using DirectDraw. I noticed that the tutorials that i took in vb dont release any of the surfaces. Is this done automatically or am i meant to do like in c++

thnx in advance...

Neither C++ or VB has a garbage collector. But VB is not so hard on you like C++ is. But all the things you are defining as "new" in VB is ment to be released the same way as C++. So there is not that much as in C++ but there are some things...I can't remember if surfaces are created that way in VB...and I don't have the time to check it now....but if you can't figure it out for your self. I will be happy to look it up for you on saturday or something...


BTW do you know any great tutorials for newbies in C++ DX?

Well im not sure but i think its done automatically, Ne way ill find out wen i load more images to memory.

Ye i know a good tutorial its the one i learned off: http://sunlightd.virtualave.net/Windows/DirectX/

Its always best to clean up by setting your surfaces to nothing when you have finished with them. This is the same for most objects in VB.

Surface = Nothing

VB uses garabge collection as well as C# and anything using managed extensions.

C++ only uses garbage collection when using something like the .NET framework (since the framework uses garabge collection for EVERYTHING), otherwise C++ uses RAII.

The keyword "new" does NOT release data in VB the same way as C++. When you use new with C++, you're usually putting something on the heap in which you must manually close or kill it within a scope.
