Hello, guys.
I am having trouble mixing two audio files.
I am looking for some info on " Mixing Two Audio files using the Right Shift by two bits".
Any kind of help is much appreciated.
Thank you.

How are you attempting to mix your two audio files? Are you writing a program, using a commercial progarm, or what?
And, really, you should tell us: WHAT FORMAT YOUR AUDIO FILES ARE IN. (that might be important)

Please do not misunderstand me.
I am mixing the PCM files using the shifting method.
After words, I will convert them into the WAV format but mixing is to be done 16 bit PCM Files only.
I have already mixed them using the formula:
C = A + B - A* B / 65536;
I got desired o/ps as well, the code is running smooth and fine.
Now, my task is to mix them using right or left shift using the two bit shifter.
I was unable fine any info on the net and I am just unable to start coding.
Can you please gime some direction ?

My apologies,...I had no idea that was even possible.
...my initial impression was that you had some bad intel and were attempting that with a WAVE or MP3 format file (They are the most common format types).
A bit shift is a fairly simple operator, though, and if you read through the documentation, you should find the explanation. Here is the MSDN page: Bitwise Shift Operators[^].

no problem sir, I am happy at least I got the reply.
I am working on it and if i could get some good results, I will let you know.
Thanks much for the link.

Actually, those are just typos. Fixed post:
C++ code for implement video cutter, urgentz, plz plz.
(You know C# is just a typo of C++...  )

Hi guys,
i don't have much experience in network programming but i want to code a little rcon
tool for quake3 engine-based games like Call of Duty 2 or Call of Duty 4.
After much googling i found out that the rcon protocol of CoD2 has a 4 Byte long header
(0xFF each) and then the code, terminated with "\n".
For the connection i used a Winsock UDP connection.
But when i send something to a server it just responses "disconnect".
Can someone tell me how to create a packet that is needed for this in C++?
Greats Sebi.s

I found this: Q3 WebRCON[^], by googling. It looks like martian to me. But, I would guess that the server you connect to is expecting a proprietary message format.
This is: The TCP/IP Guide[^], a really useful reference if you don't anything about TCP/IP.

hi,
thank you for the documentation. Now i know how a UDP datagramm is constructed, but how can i implement this in c++? Do i have to store everything in a char-array and then send it with the sendto() function?
|

I have no knowledge of the RCON operation, but, I would guess that there are a series of specifically formatted packets that your server expects to see, just to initialize whatever RCON protocol exists. That's what you really need to know. If it was me, I'd contact them and ask them.

Either a char-array or a struct that you are absolutely sure has the correct layout. You may need to turn off struct alignment etc with #pragma pack.

The ideal way would be to read a book on MFC.

Hi There.
I am using sone 3rd party libraries and am able to successfully Debug build my application.
Now, when I try to Release build the same piece of code, I am getting below error messages. Let me list few of them...
error C2146: syntax error : missing ';' before identifier 'HOPTIONSET'
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
error C2065: 'VWCALLBACKPROC' : undeclared identifier
......................................
......................................
......................................So On....
Please provide some pointers/suggestions for the same.
Thanks

Make sure that your project options are the same for debug and release (concerning the include directories, the lib directories, additional dependencies, ...). In brief: everything you changed in the configuration for debug mode should also be done for the release mode.
|
|
|
|
|
I have crossed checked them, they are absolutely similar to each other. Any other pointer/suggestion will be really helpful. Thanks.

Then look through the headers, looking for lines like:
#ifdef DEBUG
struct _some_struct_that_the_compiler_can't_find_in_release_
{
int evil;
};
#endif
I hope that made the point.
Don't read the whole thing by eye - get the computer to search for terms from the error messages, and then read up from there.
Hope that helps,
Iain.

Thanks for the reply guys.
BAD NEWS>
I have cross checked project settings - Debug/Release i.e.,
(a)C/C++ > Additional Include Directories
(b)Linker > General > Additional Library Directories
Linker > Input > Additional Dependencies
Should I need to check some other property apart from mentioned above?
Also, I am not able to find DEBUG in my full code/solution. 
Just want to know, I am using same 3rd party dlls/libs for Debug/Release mode. Can they create this type of problem?
Thanks

Guys just an update >>>>
If I copy Preprocessor Defn and Runtime Library settings from Debug and copy them for Release, then I got success with Release Build but at the time execution my application just blow up....
Any clues, What I can do at the minimal level to make my Release build a success and also can execute my Release type application.
Thanks

Check the whole code out and look for uninitialized variables (specially local ones). For example you may have such a thing somewhere in your code:
CString strVariable ;
instead of:
CString strVariable = _T("");

I must admit the title is NOT clear at all. 
As you know, using spy++ you can inspect messages sent to a specific widow in a human-favor manner. Now suppose you have a program being debugged and there's a variable representing a few properties. See the following variable contains BOLD, ITALIC and UNDERLINE status of a character:
DWORD dwFlags;
...
if (dwFlags & BOLD)
{
}
...
dwFlags |= ITALIC;
...
But my problem is this variable looks like some thing like 0x2F284A08 in the debug window and it's difficult to say which flags are set at the moment. Could you show a better way to consider this kind of variables?
Thank you masters!

I have been working on this program problem for days. I am not good at this infact I am almost illiterate to the subject. I am taking a c++ class as a requirement for my math ed degree. However,I have gotten lost on the past few assignmetns and only have a couple more to go. This is the last and only Programming class that I need. Can someone please help me with this one?
Thanks in advance and havea blessed day!
