1. I wonder why things work without linking to /usr/local/sesam/lib/libssv.so if you need it.
And if links without it I wonder why you need it.

Couldn't help commenting: So a good practice is to initialize all your pointers to NULL (or 0) in c'tor (OR assign a valid address).

He he.. :)
Stupid bug..
mitmkar has already explained it. Check out http://www.functionx.com/cppcli/variables/Lesson22.htm if still not clear.

Interesting. :)
Do you have global and/or static variables anywhere ?
Also can you post:
- TForm2.h
- TForm2::TForm2() implementation

Assuming that your login form is a modal dialog, you can associate
- a class to that dialog (if I remember correctly, this is done when you add the dialog)
- member variables of this clas to the...

put complete code.. at least I don't understand half your problem.
also I didn't know C++ allowed type names to start with numbers.

If something isn't working and you donno why, please specify. If you donno how to handle some part of the assignment please specify.
We can't do the assignement for you.

If this was an assignment, then my guess is it's a trick thing and probably you're expected to write your own class that can represent a huge int like the one you have (exactly like what someone else...

Each member variable has (at least) keywords specified for it apart from name.

Are you using C++ ?!
Office-VB would be a much better choice if possible.

This isn't related to hash, hope you know that. Ideally creation of a new thread for a new topic is helpful for everyone (rather than e.g. discussing all STL doubts in one thread).

Yes I did. Come on man, after having some nice time fighting with you, I have to be mad not to.. :)
The question can still remain..

In that case post your command line.. problem should be that you've not included String.o on command line while linking..

Sure, doing a void main() is wrong. But at least if I don't have control over main() and still use exit(123) can I expect 123 as the return code of the executable on command line? Assume we're using...

Nothing else than this (http://www.daniweb.com/forums/thread70096.html) can help you my friend..

my guess is you're missing one of the std libs to be passed on command line to the linker.. one that contains definition for String class..

JRE is platform specific. You can't ftp /usr/bin/java from *nix to a windows machine and expect to run a java program using that.
By not writing it in assembly they don't save on that front. I...

Yeah, I first noticed that "java" executable is written in C/C++ when I had some hotspot error and it wrote down a core file, whose pstack showed calls from main()->createVM()... So it's C at least...

Interesting question, to rephrase:
If i have a void main() and in the code I write exit(11). When I call this program from command line what will be return code of it?

preprocessor directives/macros are processed at the time of compilation. Arguments relevant to preprocessor (e.g. -DXXX=value) are passed to compiler and used by compiler. Any argument passed on...

You just lived up to your name.. :)

Next you'll say Earth is the center of Universe.. :D

C++ is superset of C.

Depends on what your friend means.. does he mean use C++ language features to solve the problem that is solved using C..
Or does he mean just make this code compile using a C++ compiler.. ?

Must be something to do with the way you're using them.. parameters etc.. see which object file or .so or .a file contains teh required symbols and add that on link cmd..

Yes. But AFAIK it would be useless because that variable...

Now as Vijayan has enlightened us, it's not possible to have template+virtual. So I'll answer assuming the sort function is a non-template virtual function.
You are right in saying the sort algo...

Post the errors you got.. (copy paste, don't use your own words to describe)

Seems like someone asked the question, some else read read the answers and followed up with more question and finally someone understood all and thanked. :)
If solved mark the thread as solved..

This thread (http://www.daniweb.com/forums/thread70096.html) is meant for such questions.

>> Is a base and derived class overkill for a sorting function?
Yes (because for all practical purpose you would want your sort function to have bare minimum overhead, e.g. virtual call in this...

Just one addition, in case of passing by pointer you would be dereferencing the pointer to pointer everytime you use it. Although compilers may optimize it. A reference works as an alias.

Now that's perfect question to be answered with someone's signature (I really searched for it and couldn't find) which goes something like:
"Although it might be possible to collect the twigs using...

In very gentle words NO.
Output of this code:
#include <iostream>

using namespace std;

class base
{
public:
virtual ~base() {cout << "Inside ~base()" << endl ;}

One shouldn't do this in C++. Use C++ style casting instead (of C-style)

A pointer pointing to base class can be converted to a pointer pointing to derived class (down-casting) if the original pointer is actually pointing to a derived class type.
To enforce this is the...

Or of course you can pass it by C++ reference like:
void foo( char *& ptr)
{
ptr = new char[255];
}

int mian()
{
char *ptr = 0;
foo( ptr );

See now we know what you don't know.. :)
