C / C++ / MFC

Thanks.

Sure, Thanks a lot for responding. I will find out.

There are a lot of factors that affect how you choose a suitable IDE. Since you're a beginner, I would suggest an IDE that comes free. As CPallini suggested, I also think Visual Studio is the best IDE on the Windows platform. Here are some links on what other people think - http://www.teamliquid.net/blogs/101999-c-ide[^] http://stackoverflow.com/questions/89275/best-c-ide-or-editor-for-windows[^] http://stackoverflow.com/questions/3764389/best-windows-ide-to-try-out-c-programs[^] Here is some information about the free C compilers that are available - http://cplus.about.com/od/glossary/a/compilers.htm[^] «_Superman_»  _I love work.

dynamic_cast must be useful in parent child relation of classes. It helps to determine object type in a hierarchy. i.e - class Base{ }; class Derived1:public Base{ void der1Fun(){} }; class Derived2:public Base{ }; int main() { Base *bPtr = new derived1(); //now we want to call a derived1 function let der1Fun() Derived1* dPtr = 0; if( dPtr = dynamic_cast(dPtr) ){ dPtr->der1Fun() } else{ //Display the object is not of derived1 type } return 0; } I think this is why we need dynamic_cast.

If you want to use them as function parameters, pass them by reference, not by value. void function1(Person p) { // p is a copy } void function2(Person& p) { // p is a reference to the object passed // in as a parameter, not a copy } If you use shared_ptr, remember that you have to make every Person who will be a parent a shared_ptr, otherwise its child will try to delete it (which it has no right to do) when the last goes out of scope. If you want to create a clone of a Person, and clone its relations, you will need to think hard about lifetime management and ownership. What should happen if you tried to clone father? Should it create a clone of grandfather? That is quite simple to do, but it means father will have to delete its grandfather clone in its destructor. Then what happens if another Person has that grandfather as a parent?

How do you compute the squares? This program: #include <stdio.h> int main() { double a [] = { 0.035679, 0.079935, 0.033320, 0.042424, 0.012387 }; double sum, square; int n; sum = 0.0; for (n=0; n<sizeof(a)/sizeof(a[0]); ++n) { square = a[n]*a[n]; sum += square; printf("%g ----> %g\n", a[n], square); } printf("sum of squares: %g\n", sum); return 0; } gives: 0.035679 ----> 0.00127299 0.079935 ----> 0.0063896 0.03332 ----> 0.00111022 0.042424 ----> 0.0017998 0.012387 ----> 0.000153438 sum of squares: 0.0107261 THESE PEOPLE REALLY BOTHER ME!!

Of course the function works, it is used in List controls all over the world. It is more likely that your code is doing something wrong. For a start you are not checking the return code to see whether it succeeded or not, and if not, why. What is the current value of the index nI, and what is being returned by the call to m_arrayOtherImageFiles.GetAt(nI)? Use your debugger to trace through your code to diagnose the problem.

The MFC class corresponding to the listbox control is CListBox. If you look carefully you will find there are 2 different controls - List Box and List Control. «_Superman_»  _I love work.

thank you finally I got it..

The .clw file is gone, and, apparently, with it the ability to rebuild it.

thank you ...counted I will kip in mind...

Well, we have to distinguish between published knowledge, unpublished/internal one and achieved by experience one. Writing here we primarly hope to find the third kind... but the first two kinds are welcome, too, of course.
