First of all, are there any previous languages that you have learned, or is this your first one? Knowing which languages you might already use can help to direct you to decent learning resources.
There are differences between C and C++.
C is a standardized language. One of the major benefits of C is the fact that it does not change (as quoted from one of my CS professors). C can be compiled to many systems, and it is very, very fast. However, C also has a few drawbacks to the language. Dynamic memory is one issue (having a variable that stores strings of various sizes, for example) and requires more complex programming requiring things such as Malloc() and Free(). Another element is the fact that C is not an Object Oriented language. This is why C++ was developed.
C++ is an Object Oriented language. It builds upon the basic building blocks of C and extends it quite a bit. Classes are the biggest difference, allowing to group your various functions into "objects" (hence the Object Oriented). The nice thing about C++ is that it is backwards compatible with C.
All right. Resources.
CPlusPlus.com is a wonderful resource. They have one of the most comprehensive sets of documentation that I've seen on C and C++ to date. Also, they have very good, detailed tutorials.
You may also consider purchasing a textbook on the subject. The industry standard for C appears to be The C Programming Language by Kerrigan and Ritchie. I own both the first and second editions of this text, and I have used them extensively.
Hopefully this will be of help to you. Best of luck!

The first step is to read introductory books. You should probably learn C first because C is a subset of C++, so you'll already know the C part when you study C++.
The next step is to practice writing programs. Programming is like swimming in that you have to do it to learn it. You can't learn to swim just from reading about it.
Reading and understanding other peoples' code is also helpful.
Then more advanced books will help. I recommend Effective C++ by Scott Meyers. Design Patterns is a good book for learning how to effectively use the object-oriented features of C++.

Hello All,
Good Evening,
I converted my project from ANSI to UNICODE project. In the Unicode project, the values changing in a text doesn't reflect by itself and the textbox needs UpdateWindow() to be called whenever there is a change in it. But this kind of behaviour doesn't happen with the ANSI project previously.
Can anyone advice on this ?
Many thanks in advance.

Could you give a bit more detail? I doubt there should be such a behaviour change in your program just because you went from ANSII to UNICODE. What did you change on your code? There are certain messages/notifications which have an ANSII and a UNICODE version (these are usually postfixed with an A or a W to indicate ANSII or unicode (WIDE) versions), could it be that somewhere you are listening for the ANSII version of a message which is not being sent anymore since you changed to UNICODE and now the WIDE version is sent? Show some code snipplet how you handled changes in one of your edit boxes which no longer functions.

Hi all,
I have a rich edit control in my application(VC6.0)which display some log messages.
How can I store the content of it to a text file.
Is there any direct method to do it?
Regards,
Sunil Kumar

If you are using MFC, call the StreamOut() method. Otherwise, send the control a WM_STREAMOUT message.

unsigned int findPrimePalindromes(unsigned int array[],int start, int end)
I need to write a function base on that...
Can any one give me a kick start?
|
|
|
|

unsigned int findPrimePalindromes(unsigned int array[],int start, int end)
{
for (int loop=start; loop<=end; loop++)
{
if (ValueIsPrimePalindrome(array[loop]))
{
return (loop);
}
}
return (end+1);
}
The function "ValueIsPrimePalindrome" is left as an exercise for the reader...

Well you know: a prime number has only 1 and itself as divisors...Then you should check if it is palindrome (and that's really a simple task).

I actually wrote the program, and it works for all value except after 10 million...
I need to keep the check time into half, so for the polindrome part, I only check half the strlen...
But it still would do much help....
I know whats prime polindrome!

FILE* f = _wfopen(m_sFilespecW.c_str(),L"w");
size_t no = fwrite(tmp,sizeof(wchar_t),size,f);
fclose(f);
but it shows garbage.
when i change the code to:
FILE* f = _wfopen(m_sFilespecW.c_str(),L"w");
while(*tmp)
{
fputwc(*tmp,f);
tmp++;
}
fclose(f);
it saves the file but in ANSI format. it then fails to load in other function as that function only loads unicode files.
help me i want to save it in UNICODE.

I am developing an application that has to act on external data that is both described and provided by the user, the client.
Currently I have created a wizard and the user can choose either to provide an SQL database (thus asking him for the DSN and the SQL query) or an XML file (thus asking him to for the appropriate xQuery query) or a CSV file (thus asking him for the file where it resides and the delimiting caracater).
Now, this may not be sufficient : I can imagine a plenty of complex scenario such the data cannot fall within those 3 types.
What I am tempted to do then is to make it possible for the application to call an external code provided by the user and which will be responsible for retrieving the data so that the application can deal with it.
My application is written in unmanaged C++, but the user may want to write that portion of code in JAVA, C# etc.
My only idea, which is unfortunately still not clear (regarding implementation) is to write a sort of specification of a COM object : user must write his data-code following that spec. and my application should be able to load available COM objects that fall with particular class and allow the user to select his implementation. Then the application is capable of calling that COM object and retrieving data passed by it.
(I am not even good at COM development)
So do you have suggestion, is there a sample application I can inspire from ?
Thank you in advance.

If the COM-based idea is possible, the question then how would I deploy the specs ?
Would it be in form of an IDL file ?
Is it then possible to take an IDL file and construct a COM project from it ?
