The first line was enough! Thank you very much! Sometimes, well maybe most of the time I'm so stupid. That's so obvious!

Being a bit pedantic here (but it's necessary!)...
Since the order of evaluation is not defined by the language spec, the compiler writer is free to choose, so your second example
sum(--number) + number; could come out either way (but number will always wind up decremented). There are lots of examples of confusion over this.
Cheers,
Peter

I concur, at least for C. I just don't know for recent versions of C++.
And I would never write a statement like that.

Hello
i am currently facing this problem, i am doing a kind of game where when the user presses a key like the 'a' key it makes jump the object, but how to detect key press in a way to know how much jump, if you press the key for a tiny time do a little jump or if you got pressed the button too much jump only a maximum.
Thanks

Did you read the documentation, specifically about bits 0-15 of the LPARAM parameter?

I am new at c++, and ;I am trying to use existing library that contains .c and .h files.This library also contain one test program.I have included all .c and .h files to my project. When i try to build my project I get the about 10 different "LNK2019: unresolved external symbol errors". maybe some one can help me figure this out.I have checked that .c and .h files contain these function i-e mzd_copy,mzd_echelonize_m4ri etc. I am using visual studio C++ .net 2008. I have uploaded my project at mediafire
http://www.mediafire.com/?6bcuo1tmg3smysc
the error i received are as follows:

Your function definition might be a mismatch with the function declaration. Make sure you are using the correct prototype.
The linker error indicates that your code is unable to find a matching function.

Check the source file that contains all the functions with the _mzd_ prefix is being correctly compiled and included in the project.
I must get a clever new signature for 2011.

hello,
i am not able to download your project from the link you gave. anyway, is there any lib file and if so, did you include that in project settings->linker....

Hi,
Thank you everybody for the quick feedbacks.
Here is the link again. Its working.
http://www.mediafire.com/file/6bcuo1tmg3smysc/test333.rar[^]
I have confirmed that all of the implementations used in my test project are available in the source and their corresponding header files.
I have added all the required files to to my source and header folders of my project.
There are no pre-compiled .lib or .dll files. I have got all the necessary files in .c and .h format. The library also has extern C symbols added so that it can be compiled as a C++ code.
I can easily jump to function implementation in header file using "Go to definition" in VC++ editor from my test .cpp source file. But still nonetheless i am getting linking errors.
Kindly please have a look at the project source.
Thanks a million
Regards,

Please see my previous message. Your project has not included the files in the m4ri folder so the mzd functions are not being compiled. You should either add all these source files to your project, or create a project that compiles them into a .lib file (static library), and add that to your main project.

Hi,
Thanks a lot for your quick reply.All of my .c and .h files are available in m4ri folder.
Will you please tell me that how I can create project that compiles them into a .lib file(static library), and how can I can add that to my main project.
Thanks a lot.
Regards,
Ishtiaq

Yes, I know they are available in the folder but unless you compile them into object code your program will never be built successfully. If you do not know how to create such a project then I suggest you go to the Visual Studio help pages and read up on the compiler and linker options for building different project types.

hello,
i can able to download now. i saw your project.
Mr. Richard is right. do as he said, then you will get the result.

What happens when you try it?

Yes.
Initialize it by updating the m_ofn (OPENFILENAME) structure with the appropriate path.
the "my document" can be found with SHGetFolderPath.
Watched code never compiles.
