This is only because there is no compiler out there that meets this part of the standard (mainly due to the insane complexity it takes to accomplish it). The standard allows for placing template definitions in header files and implementations in cpp files.
To get around this problem, I generally either put the entire class definition and implementation into a single file, or I place a #include "myclass.cpp" at the bottom of my header file.

yes i know that, but that fact is that actually, so i didn't want to pollute the post with something that wouldn't have helped...

Probably problem is you have used TCollection class object without using argument list.
You need to use it like this,
TCollection<int> objTCollection;

Well I do appologise if my English offends you, although it appears the other members (forum members that is and not class members before you get confused) here did not have such a hard time understanding me. May I ask, Mr.Anonymuos, do you use the same attitude when your customers come to you with a problem?

When defining you must explicitly declare the function as template:
<br />
template <class _T> TCollection<_T>::TCollection () : pData(0), pCount(0)<br />
{<br />
}<br />
template <class _T> TCollection<_T>::~TCollection ()<br />
{<br />
clear();<br />
}<br />

well, you're right.

Separating template classes into .h and .cpp files is too much of a headache when you're just starting out with templates. It's far easier to put everything in the .h file. See the C++ FAQ Lite[^] template section for more details.

Hi!
I have a question about dynamically allocated memory, actually about cleaning that memory.
For example I compile and run this piece of code:
char *pString = NULL;
if ( (pString = new char [100]) == NULL )
exit( EXIT_FAILURE );
... <--- Use pString
delete [] pString;
The question is how does the program know how much memory (how many bytes) to free (deallocate)? Isn't it compulsory to specify the number of bytes between the two brackets in order to be sure that it will free all the dynamically allocated memory? 
Any suggestions would be greatly appreciated!
Thanks in advance!

Each heap allocation keeps track of its size.

Did you read his question ??
The link you posted has nothing to do with new and delete, it is purely C programming (alloc, malloc, realloc, ...).
When posting a link, at least take the time to verify if it contains valuable information for the OP.
Just googling and pasting the first link that cames up is not really helpfull.

It seems I must read complete a thread not only title,thanks for remind,sometime when I see a title I guess body is like title (thanks), but i dont think that stuff and paste link is good,yes?

  Of course !! That seems logical no ? How can you describe completely a problem in one single title line ??
WhiteSky wrote: but i dont think that stuff and paste link is good
It depends. Sometimes it is usefull, but sometimes it can be really annoying. For example if that links to a lot of text and if the OP needs to search a lot to find the information, it is in general not very valuable. And if you provide a link to something you googled for, then at least verify that it contains the information.
We ask the people who post the questions to have some respect for the other (so formulate the questions correctly, use proper english if possible, ...) but the opposite is true also.

I am on a console application that supports MFC. In turbo C under dos, we can use the clrscr(); command to clear the screen. Is there any equivalent which I can use in my case (console app that supports MFC)?
Thanks

Try this:

using system() is bad. windows provides an API for consoles, but i don't remember its name...

Thanks for making me recall that. It was just a quick suggestion.

hi group!!
i have got one bmp file and i want to convert it to ico file
actually i want to create logo for application
so what is the way for it?
are there any readymade softwares!!
please help me 
thanks and regards

Is this related to MFC or C++??
Why not just opening it in MS paint, and saving it in a ico format??

Have a look at CreateIconIndirect(). In the ICONINFO structure specify your bitmap as the hbmColor bitmap and create a monochrome black bitmap with the same dimensions as your bitmap for the hbmMask bitmap.
You may be right
I may be crazy
