You need to include any .h files that have the typedef, function, and variable info right into your project. I had the same problem.. just doing a #include doesn''t give you the drop down info (actually, it''s called auto-complete).. Include the .h files.
Also, VC++ 6.0 has some sort of bug (at least on my machine) that doesn''t give you the drop-down for member variables or functions after you execute a DX8 program on the first run. Why? I don''t know.. I do know it''s trying to display it, because I can tell VC++ is trying to show it, and the bottom status bar shows that it is there... Actually, I can still select members from struct, classes, etc.. But the actual drop-down is invisible. Can anyone tell me what this is? It still gives me the parameter info for functions, but no drop-down. Good luck, just include the .h files.. to answer your question.
Visual Assist is amazing. It is a intellisense (that thing that drops down and shows you methods and member variables) enhancement that really speeds up development. I totally recommend you download the demo, i started using it 2 days ago and am definately going to purchase it when my demo time is up.
Code comment of the week: bool hack = false; // DO NOT CHANGE THIS EVER
Had the same problem as you, and I fooled around a bit and after a couple of restarts of VC I went into Project settings (Alt+F7) and checked the "Generate mapfile" option.. I doubt that this option has anything to do with the statement completion option, but I think it forces VC to read through the header-files, and VOILA.. my parameter-drop-down-list works...
