Hi all, I am getting starting with MDX, specifically for VB.NET. I am a little confused about all this MDX 1.0, 1.1, 2.0, XNA...Microsoft really made it as hard as possible for newbies. Anyways, I currently have MDX version 1.0.2902.0. I cannot do anything related to DX8 or 9. I can use Directdraw fine, but DirectXEvent8 can't be found. I have added the references to my project and imported them to my class. My app runs fine now, but I am trying to add DirectInput. I want to use the SetEventNotification(), but I am having a ton of trouble. I want an event to fire instead of me doing Pooling(). Is there any example or any tips of how I can enable DX8 and 9 to use? This is what i want, but this properties/methods don't exist for me: http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/dx81_vb/directx_vb/Intro/ProgramVB/ClassRef/directxevent8.dxcallback.asp Thanks a lot. Zach

Well I was able to the find directx8 library - udner the COM references. Are these what I should be using? My understanding was I wanted to use purely the MDX (.net references?)

Thanks.

It sounds like an old VB6-era library and not MDX. I've never heard of a version of MDX for DX8, only DX9.

Anyway there are really only three versions of DirectX for .Net:

MDX 1.1 - Discontinued, but the closest you'll get to a real wrapper for DX9, most of the functions take the same parameters as their unmanaged counterparts. Unfortunately I've heard it doesn't work on 64-bit operating systems, and it looks like it never will(Thanks MS).

SlimDX - This is an open source wrapper, similar to MDX but with support for both DX9 and 10. It's managed by several people here on GameDev.

XNA - Microsoft's "new" API, works on Windows and XBOX360(although you need a subscription). Abstracts a lot of things to make it easier to develop with. There's also an editor that allows you to drag-and-drop different components, similar to the GUI editor, but for games.

Thanks for your reply.

Do you know if MDX version 1.0.2902.0 is 1.1? I can not find a download for 1.1 from msdn.com or google search.

I will check out the SlimDX.

Thanks.

Yes 1.0.2902.0 appears to be the last version(although I have a 1.0.2911 version of D3DX). I think the reason for the "1.1" is that when it was developed there was only .Net 1.0 and 1.1, and it only worked with .Net 1.1(and over, of course).
