The mappings are in "winnt.h". If you want to map IDs to strings like "Arabic (Egypt)" you'll have to do it yourself.

Hi all,
I'm currently doing my final year dissertation, being on wireless transmission in a client-server model. Can anyone suggest any dense literature about technical detailed c++ programming such as enabling communication between server and additional programs (such as ffmpeg), excessing USB devices (such as webcam, mic, video capture card) and the like..
Thanks in advance, any help will be much appreciated

typedef struct _ABC
{
//....
}ABC;
how to undef ABC here?
this is for correcting/updating VC lib errors.

Could you elaborate a bit on that ? Because I think you are trying to solve the problem in a wrong way.

how do you get a feeling of "wrong way"?
for this <winbase.h>
typedef struct _OSVERSIONINFOEXA {
DWORD dwOSVersionInfoSize;
DWORD dwMajorVersion;
DWORD dwMinorVersion;
DWORD dwBuildNumber;
DWORD dwPlatformId;
CHAR szCSDVersion[ 128 ];
WORD wServicePackMajor;
WORD wServicePackMinor;
WORD wReserved[2];
} OSVERSIONINFOEXA, *POSVERSIONINFOEXA, *LPOSVERSIONINFOEXA;
typedef struct _OSVERSIONINFOEXW {
DWORD dwOSVersionInfoSize;
DWORD dwMajorVersion;
DWORD dwMinorVersion;
DWORD dwBuildNumber;
DWORD dwPlatformId;
WCHAR szCSDVersion[ 128 ];
WORD wServicePackMajor;
WORD wServicePackMinor;
WORD wReserved[2];
} OSVERSIONINFOEXW, *POSVERSIONINFOEXW, *LPOSVERSIONINFOEXW;

You cannot remove a typedef.
These are 2 versions of the same struct, one for unicode (W) and one for non-unicode(A)
There should be a third typedef that will use one or the other depending of your project settings.
something like
#ifdef unicode
#define OSVERSIONINFOEXW OSVERSIONINFOEX
#else
#define OSVERSIONINFOEXA OSVERSIONINFOEX
#endif
Normally one will use the third typedef so that the code can be easily converted to/from unicode without having to manually change the code.
So, what't the errors/problems you originally had ? compilation errors ? runtime errors?

Do you know how many reserved data have been used today?

huh ? talking about the wReserved field of the structure ? so what about it ? it's reserved, you should not really care about that. use GetVersionEx to get the structure and be done with it; me think the usage is simple, unless you want to make it complex for no reason at all.
please refer to this[^] post if you want more help... because now, I'm not certain what question you are asking; we're not mind readers.

You are far away from my post.
If you don't care about this, you just use it, no one blames you.
This struct and many others have been redefined for many times by many programmers, people have their own reasons to redefine them, I suggest you do not tell them what you said as quoted sentence.

Once again you seem to be losing the plot here. If you have a problem with your code then show what you have tried, explain the problem, including any error messages, and people will try to help you. But don't start being abusive just because you don't get the answer you think is due to you.

Is my post clear? is any replies of the post clear?

No it is not clear, which is why I suggested that you explain what you are trying to do and what is not working.

His replies were very clear while most of your posts fall into the belligerent a**hole category. If you'd learn to ask a reasonable question and display a few manners, you might do a lot better.

While he does display that characteristic on occasion, this time he is just asking outright senseless questions. The term "chasing rabbits" comes to mind.

A number of people are trying to answer your question, but first they need to understand what the problem is. That is why they have asked for more information.

Is "plot here" only "any error messages"?

I apologise if that statement is not clear, it is a common English expression, which means that we are arguing about the wrong things. Let's get back to your question and find out what it is that you are having trouble with.

Thanks, but I've seen you do the same! I'm actually trying to follow Chris's rules that a) we help people and b) we don't make them feel stupid. But with some of our questioners it really is a challenge.

First: You cannot undef a typdef.
Second: Can you give us an real example (not just struct declaration) where you have a problem; give as much information as possible.
Third: Let's work together and try to find a solution to your problem.
Fourth: I have some errands to take care of, will be back in a couple of hours.
---------
According to you, there's an issue with the OSVERSIONINFOEX structure (and maybe their variants ...A and ...W)
Can you give us an example on how you use them ? actual code that use that structure and please highlight sections where you think there's a an error in either you code, MSDN documantation and MSDN usage of said stucture.
If it's a compilation error, please report the errors given by the compiler (and what compiler/ide you are using).
If it's a runtime error, please report the call stack and the input values that could be generating that error.
Please, we are not mind readers, and you do not give us much meat to even start giving you a good answer.
Have a good one,
M. (will be back in a couple of hours)

Hi,

The Short answer is: Cannot be Done! To ask the question in the first place shows a lack of understanding on how the various pieces of the jigsaw are fitted together when you build an application. This is a vast subject, which cannot be adequately covered in this answer. However, the following is a short answer.
The Headerfiles in general do not contain code. They contain information required by the compiler, (akin to a User Manual for a library) to build modules in such a manner that the entre project can successfully link with the libraries. If you want to upgrade the horsepower of your car, you do not do so by changing the User Manual, but by changing the Engine.
So, an 'untypedef' does not exist, because it cannot serve any usefull purpose.
<blockquote class="FQ"><div class="FQA">includeh10 wrote:</div>this is for correcting/updating VC lib errors.</blockquote>
Hmm...
Well, if you must...
There is no point in changing Header Files, or 'untypedeffing' anything You must Rewrite the Libraries, using exactly the same names throughout, (The best way of doing that is using the existing header files), and save the result in your Windows/System Folder, replacing the Old and Faulty VC libraries.
Success with your Repairs/Upgrades.
