I get following error when compiling my very first VC60 program:
"--------------------Configuration: Titan - Win32 Debug--------------------
Compiling...
StdAfx.cpp
Compiling...
audio.c
k:\titan\source\audio.c(77) : fatal error C1010: unexpected end of file while looking for precompiled header directive
"
Obviously the compiler is looking for something in my 'stdafx.sbr' file that I am not providing.
Does anybody know how to resolve this simple hangup?
Thanks!

Maybe you should rename you file form .c to .cpp

Go to your project settings and look for settings on precompiled headers. 'use precompiled headers' will be checked, instead check 'automatic use of precompiled headers using file" and make sure the file is stdafx.h. Basically, if you use precompiled headers, all your .c and .cpp files need to include stdafx.h before any other include. When you import a file from a project that does not use them ( which is what I assume you've done ), you need to either add the line or change the setting.

Hi,
[1] What is the best way to read avi files?
I have a class using the raw AVI* functions but it does not seem to be able to
load all formats. Some can't find an appropriate decompressor even though one is installed and the video plays ok with media player. I assume that DirectShow is implemented from those core AVI functions so is my assumption correct that reading/writing all avi formats should work without using DIrectShow?
[2] What is the best way of being able to open arbitray mpegs or avis and obtaining the
buffer?
[3]
Also In an SDI app how would I change the CFileDlg before OnOpenDcoument() to restrict the display formats. e.g. just mpgs or avis.
Thanks

On MSDN, Microsoft says "Microsoft® Video for Windows® (VFW) provides functions that enable an application to process video data. VFW was introduced in 16-bit Windows. Many of its features have been superseded by features in DirectX."
From the DirectX SDK You'll want to check out the DMO Sample. It takes MPEG-1 video packets as input and produces two output streams. You'll also want to take a look at the PlayWnd Sample, which is a simple media player.

You don't need to do much work with OnOpenDocument If you change the document string in the resources.

Hi folks,
I've got a problem with delayload. Linking my C++ project in my venerable Visual Studio 97 delayload works fine. However, I've just downloaded the free VC++ toolkit 2003 which includes a new compiler and linker. With the new linker I get the error "unresolved external symbol ___delayLoadHelper2@8". Researching this I find that Microsoft have renamed the DelayLoadHelper routine to DelayLoadHelper2 and that I therefore need the new delayimp.lib - but strangely this isn't included in VC++ toolkit 2003 nor is it in the Windows SDK (there is a 64 bit version though). Does anyone know where I can get the latest delayimp.lib file?
Thanks, Chris

I'm a newbie to regex so please take it easy on me.
What would be the best approach for parsing C++ templates (inline functions only) and extracting some comments so I can generat a bit of documentation?
I'm interested in the approach (or regex if you feel generous) in parsing source code and generating primitive docs from it, NOT in finding an already made solution like the many source code doc generators out there already...so please don't send me links to DOxygen or anything....unless it outlines the techniques they used
I basically want to use a special commment like
// TODO: Blah blah
to generate todo lists and also extract class interfaces (including private and protected)
Any ideas???
Cheers

A regular expression would be simple to do the "// TODO:" searches and output the results to wherever. But I think VS.NET already does this for you in their tasklist addin. And also just doing a strstr would be faster and less involved then using a regex set. As for parsing C++ templates you'd have to incorporate into your regex parser the grammer for C++ templates which most people would probably just pull out of gcc and use flexx/bison (lex/yacc) to build up what they needed to parse the c++ templates which would do the regular expressions for you. Then you just plug into the grammer where needed to generate what you wanted at the times you wanted it.
As for printing your voice mail. Hook your VMail system up to a Speech to Text(S2T) system and then connect your S2T sytem to a parrellel port that connects to your printer. Then push your VMail into the S2T the output of the S2T into the printer to get your vmail to paper and thus printed.
Cheers,
-Erik

It's actually not for C++ it's for PHP and the editor I use doesn't support VS addins i'm afraid
The TODO I already have figured out

I'm looking for simplicity in development and I have a helluva time understanding parsing grammers...i've already looked into Spirit and i'm not exactly blown away by it's ease of use...I need just a simple doc gen so i care not if it's inefficient...
I want to use regex because I figured it would be easier to do something like:
1) Find any TODO: which folows directly after // or /* and continues until end of line or corresponding */ is found (if applicable)
2) Find all characters after TODO: and before EOL or */
Thats my TODO list
As for finding classes (im thinking):
1) find class cls_name{}
2) Extract the class name and store in vector
3) Get any comments preceeding class declaration which have a \brief switch directly after // or /*
4) Extract each of classes member functions and variables
5) Pull comments about each member as well
Once i've complied a couple vectors with this information I figure I could easily generate HTML docs
And i'd be happy

I'm a bit confused - so If I've got it wrong and you actually want to parse PHP please forgive me  .
If it is C++ that you want to parse my suggestion is that you don't even try. It's far too hard - use something else someone has already done. Even doxygen, which is brilliant at what it does, clearly states that there are problems with the parser (I've never seen them, but I'm sure that the Doxygen team would know). Doxygen does however ship with source, and with some (rather large) tweaks i'm sure you could get it to output what you needed.
If you've looked at spirit it might be worth looking at boost::regex which contains at least a partial scan of a C++ file for keywords and classes, but I doubt that's what you're looking for.
If you need to get more information than doxygen (especially the XML output of doxygen) can provide, I strongly suggest you at least check out GCC-XML[^] which outputs the GCC compiler database to XML - everything except for method bodies (which you didn't ask for) and comments (which you seem to have sorted anyway) are included in the output.
GCCXML was a pain to set it up to work inside VS.NET but it works quite well unless you use huge numbers of templates (eg/ the boost libraries) and then the problem comes down to the (albeit small) differences in the way Microsoft and GCC compilers parse code. The output files from GCCXML are enormous, so finding good ways to filter out the data that you don't want is critical.
Good Luck!

I'm using boost actually but I couldn't find the C++ scan example??? I'll have to look again...i'm not actually parsing C++ just extracting some details like
DOxygen...
probably a little less

Have a look at:
boost_1_31_0\libs\regex\example\snippets\regex_grep_example_1.cpp
but all the examples are pretty good, I think one is even a pretty printer for C++ code

Well you probably would have to make a parser yourself, probably search a specified file(s)/folder(s) and then search through them for '//TODO:' and then use getline or copy the contents until you come up to a \n

Hello,
I am an experienced C++ programmer especially on the Win32 platform (MFC, Win32 API, etc.). I am limited experience on intensive graphics programming including OpenGL and DirectX. I have some general questions about graphics programming.
1) I often read about how DirectX does not work well with MFC. Is that accurate?
2) Is DirectX platform independent?
3) Is OpenGL platform independent?
4) What do graphics programmers including gamers use: DirectX or OpenGL?
5) What is more extensible, and essentially, better graphics API on the Win32 platform? What are some good books for learning this graphics programming tool?
6) What is the future of graphics programming especially on the Windows platform?
As you can see, my experience and knowledge in graphics programming is quite limited. I'd appreciate any insight.
Thanks,
Kuphryn

1) I often read about how DirectX does not work well with MFC. Is that accurate?
Sounds like a complaint from someone who didn't understnad how to use MFC very well, but then again I could be wrong.
2) Is DirectX platform independent?
No it's only for the Win32/x86 platform.
3) Is OpenGL platform independent?
Yes it is, OpenGL runs on linux, unix, irix, OSX, Win32, Solaris, and several other platforms.
4) What do graphics programmers including gamers use: DirectX or OpenGL?
My understanding is that if you're going to write games, particularly for Win32, DirectX is slightly better as it has a number of features that are specifically targetted at game programmers. However if you are going to write CAD/3D modeling, etc kind of applications, especially if they require high precision, then OpenGL is much better.
5) What is more extensible, and essentially, better graphics API on the Win32 platform?
I personally dislike COM intensely, and DirectX is all COM, unless you want to start using the new managed DirectX libs. I personally would prefer OpenGL.
6) What is the future of graphics programming especially on the Windows platform?
Well, aparently it is all gonna be Avalon, and managed API's. GDI's days are numbered, supposedly. I take all of this with a grain of salt though.

A couple of OpenGL references
1. Try the Red Book[^]. Very extensive.
2. Try Gamedev's OpenGL tutorials[^] for OpenGL
and
3. Gamedev's DirectX tutorials[^] for DirectX
i hope this helps

This is a great question, and, I know too little about it.
However, I would recommend Feng Yuan's book,
"Windows Graphics Programming", published 2000, written for the Windows 2000 platform; it is all about a non-MFC, C++ class approach to high quality graphics. It includes a section on DirectX, but, no OpenGl.
Everything I know about graphics I learned from this book.
The author includes a CD with a huge library of professional quality Windows graphics classes source code and dozens of really useful demo programs.

I saw this a few years ago in a bookstore and almost bought it. Is it as good as it looks - I glanced through it and it seemed really good.

It's an awesome book, even if GDI+ makes much of it now redundant.

That's the most stupid thing I ever heard. I spent two years working on a project that mixed DX with MFC and never once heard a complaint. We only ditched MFC to start on a version that used our own windowing library, written in Python.

Nope
kuphryn wrote:

I believe so, that is, there are GL implimentations for multiple platforms.
kuphryn wrote:

My understanding is that a lot of games get written for both, as some cards work better with DX, some with GL. I reckon DX will win in the end.
kuphryn wrote:

There are two Open GL books, the red and blue books ( forget the names, but the covers are red and blue  ). One is a 3D programming reference, the other a GL libray reference. The trouble with DX is it changes so often, most books written are obsolete as they hit print. Better off to buy the GL books for 3D concepts, and use the DX SDK docs.
kuphryn wrote:

In my experience:
Most gaming companies do not make a profit, meaning that games programmers often are people who change jobs a lot. General graphics coding is the sort of thing that can make you a lot of money, as it's specialised. I get a bit of contract work in graphics even nowadays, and I've been doing web stuff for my day job for a couple of years now. However, demand has got to be low, how many paint packages does the world need ? Scientific/medical work may be a whole different ball game. It's lots of fun and really interesting though, that's why I keep doing it.
