i wish to make some registry entry at the time of installing my software and use the entries later in my sofware..
should i make the entries in HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE? basically, i want to know which is the appropriate path.

It depends. If you want all users of that machine to be able to use you software then you need to saved it on HKEY_LOCAL_MACHINE. But if for currently logon user only, then save it to HKEY_CURRENT_USER.

Use FindFirstUrlCacheEntry(), and pass "cookie:" as the first parameter.

Pinky, are you pondering what I'm pondering?
I think so Brain, but if we shaved our heads, we'd look like weasels!

I am trying to do some simple inheritance with a few classes but keep running into an error at compile time. It is error C2504, 'undefined base class'. What does this mean. My classes are defined, I think they are anyway. This is what it looks like.
class a{
};
class b : public a{
};
I am including the files as well. I am just kind of stumped.
Thanks Brian.

Make sure you include the header file of your base class in your derived class.
1. say you defined class a in "a.h" file
class a
{
};
2. In class b header file
#include "a.h"
class b: public a
{
};

?Don't ask the same question twice. The above is missing a }, so I assume it's not the actual code. Are you including the header for the base class in the HEADER for the derived class ?

Yes, I am including the header files. Here is some of the original code.
#ifndef ABSTRACTFACTORY_H
#define ABSTRACTFACTORY_H
#include "concAbstFactory.h"
#include "abstractFactory.h"
#include "productA.h"
#include "productB.h"
using namespace std;
class abstractFactory{
public:
abstractFactory(){}
productA makeProductA(){
return productA();
}
productB makeProductB(){
return productB();
}
};
#endif
#ifndef CONCABSTFACTORY_H
#define CONCABSTFACTORY_H
#include "abstractFactory.h"
#include "productA.h"
#include "productB.h"
using namespace std;
class concAbstFactory : abstractFactory{
public:
concAbstFactory(){
cout << "Building concAbstFactory" << endl;
}
};
#endif

Strange. What was so wrong with that. "concAbstFactory.h" is another class that I am going to need to derive other classes from later. Hmmm.
Getting rid of it did help though. Thanks for your eagle eye.

Ok, say we're trying to compile abstractFactory.h... The compiler starts the pass, and hits the #include "concAbstFactory.h" statement, so opens the file and starts to process it, where it finds the line #include "abstractFactory.h". When it opens this file, it gets caught by your #ifndef (since the file is already included), and skips over the file. Returning to the concAbstFactory.h file, it tries to process the class definition but since it hasn't reaches the declaration of abstractFactory yet, it complains that the base class is not defined, which is correct. So basically, the compiler is seeing the lines in this order:
#ifndef ABSTRACTFACTORY_H
#define ABSTRACTFACTORY_H
#include "concAbstFactory.h"
#ifndef CONCABSTFACTORY_H
#define CONCABSTFACTORY_H
#include "abstractFactory.h
/* abstractFactory.h */
#ifndef ABSTRACTFACTORY_H
#endif // Skips over everything in between since the definition is now true
/* concAbstFactory.h */
#include "productA.h"
#include "productB.h"
using namespace std;
class concAbstFactory : abstractFactory
...etc...See the problem?

Hi Sirrius,
The problem was very well described by Ryan.
The solution to fix your compilation error is to delete both #include statements.
Here is an example of a simple yet correct way to include header files like your are trying to do:
File ClassA.h:
#ifndef CLASSA_H
#define CLASSA_H
#include "ClassB.h"
#include "ClassA.h"
class a
{ ... };
#endif
File ClassB.h:
#ifndef CLASSB_H
#define CLASSB_H
#include "ClassA.h"
class b : public a
{ ... };
#endif
If you want to derive other classes from concAbstFactory then simply include "concAbstFactory.h" in the header files for those new derived classes. Your base classes should not have any knowledge of your derived classes.
Hope this helps.
Eric

In the file that defines class abstractFactory, you're including the file that defines class concAbstFactory:
#include "concAbstFactory.h"
concAbstFactory is derived from abstractFactory (which hasn't yet been defined at this point), so there's your hiccup. Remove the include statement mentioned above and try again.
Including the headers of child classes in their base class should make you nervous.

Hi
I just installed STLPort on my system, and I find it superior to Dinkumware's implementation of STL. However, I am now building a library that will be used by a lot of users, and not all of them have STLPort on their system. Is there a way that I can build my library and still make it usable on all systems?
Thanks!

Any STL implimentation is going to be in the form of code that you include. So it's already in your program, the compiler puts it there.

Hi
I wanna capture the desktop and save it to a jpg file, I know how to save it to a bmp file uncompressed but that file is to large 3 megs!!.
So I try to modify the code for capturing to an bmp
and I can not view the jpgs I create
what is wrong?
where am I wrong
here is the code:
[code]
