I think MSXML supports both SAX and DOM way of parseing the xml file. It would be good thing to use unless you dont want to use COM in your application.

For standard C++ programming and also WTL programming, is VC++ 2005 a lot better than 2003 ?
Is the IDE a lot better in 2005 ?
Is it worth upgrading from 2003 to 2005 ?

I dont know about you but I find the new Visual C++ to be a lot cleaner than the previous VC++. The simple reason being the concept of partial classes where the code wizard writes code in a separate file but for the same class. So there is 1 file with your implementation and one with the code gen. There is no need to find you way through the code and make changes or insert code as in 2003 at times. It does not support .net 1.1 framework but does it for .net 2.0. The GUI that u can build is very Office 2003 like...so it looks updated
cheers

I ave tryed 2003 and 2005 but after some disaventure (serialization of CObject defined in extension DLL see IMPLEMENT_SERIAL_EXTDLL ecc.. distributing executables ecc..) I use VC++ 6!

The upgrade is worth doing.

 ;P
not so bad, but quite old nowaday 
i still use it, but only when i maintain a project a create under VC++6 that i don't want to port to VC++7.1.
now, when i create new projects, i use VC++2003 (i don't have VS2005 except a beta2), and i find it pretty cool compared to VC6 (which keep me nostalgic  )

Yep, still a good IDE but there are some minor bugs with the compiler. If I remember correctly (not sure anymore), you will have compile errors when you have a class with a private destructor and a public function that auto-deletes the object (something like):
void MyClass::Destroy()<br />
{<br />
delete this;<br />
}
The compiler will tell you that the class cannot access the destructor as it is private.
There were also some minor bugs with the STL I think but I cannot remember anymore which ones.

Morning, got a quick question here 
<br />
for(std::vector<std::string>::iterator iterString = myVec.begin(); iterString != myVec.end(); ++iterString)<br />
{<br />
if (*iterString == "someText") *iterString = "someOtherText";<br />
else if (*iterString == "someText2") *iterString = "someOtherText2";<br />
else return(-1);<br />
return(0);<br />
}<br />
Will changing a vector item using this kind of operation invalidate the iterator?
I cannot red it up: No docs, no books here, just the compiler, libs and web access.
Thanks in advance.
Cheers,
Sebastian

I would be very astonished if it does. Think of an iterator as a kind of pointer: when you access and change the content of the pointed data (with the * operator), it doesn't change the pointer itself so it is still pointing at the same 'address'.
Altought I never tested it before so I cannot say that will work. But still, this would be very illogical if you can't do it.

i think that such a question sebastian asked is justified when you know Java iterators... they actually invalidate when you try to modify the element they point on (or something very close).
but even if it is not the case in C++ (because modify the element will not reallocate automatically a new instance - which makes the iterator loose its address), i can understand his doubt...

Thanks for you help, you two.
Actually, I was concerned with the "dynamic" nature of a vector. I was not sure how vectors handled resizing. I mean, I did not consider the nature of the std::string and std::vector. But your statements make sense: Even if the string did grow during my change, that would not require the vector to grow, since the string itself handles its own "dynamic size", not the vector containing it.
Its a typical case of "not thought through"
Thanks again.
Cheers,
Sebastian

This will not invalidate the iterators. Things what will:
- Inserting a item at the end **IF** reallocation occurs as a result.
- Inserting an item invalidates all iterators the refer to items after the inserted item and if reallocation occurs all iterators.
- Deleting an item invalidates all iterators the refer to items after the deleted item and if reallocation occurs all iterators.
I think that about covers it.
You can use the reserve function to specify how much storage to allocate so reallocation does not occur.

I have 2 classes, CPerson and CPersonDlg. Look at their relationship:
Person.h
--------
#include "PersonDlg.h"
class CPerson
{
...
public:
friend class CPersonDlg ;
...
} ;
PersonDlg.h
-----------
#include "Person.h"
class CPersonDlg
{
...
public:
CPerson m_pers ;
...
} ;
Person.cpp
----------
#include "Person.h"
....
...
PersonDlg.cpp
-------------
#include "PersonDlg.h"
...
...
PROBLEM
=======
I am getting the error "fatal error: unexpected end of file while looking for precompiled header directive". But If I add "#include "stdafx.h" in Person.cpp, I get another error "CPerson: class type redefinition"
Pls suggest me a solution.
Thanks in advance

In the project settings (right click on project in solution explorer -> properties) select "C/C++" and change "Precompiler headers" to "Not using precompiled headers". I also suggest removing stdafx from your source-code.
And: remove the circular includes, thats giving me the creeps. Have PersonDlg.h include Person.h.
Cheers,
Sebastian

To solve the first error you have to #include "stdafx.h". To solve the second error place a #pragma once at the top of every one of your .h header files. What is happening now is that the compiler is including person.h multiple times so it is finding multiple definitions of class CPerson.

1. I have one similar problem please help me also. I tried to use a global variable in every c++ file with the same name that is szRegPath (a CString). But I got some error and I had to use either different variable names in all the files (if global) or i had to put those inside functions. How can I resolve this?
2. I want to have one int variable which is global to all the c++ files and that should maintain its value state. If one file modifies the value to 7, then when it is called by another file, it should have its value as 7.
Please help me

Declare the variable as external using "extern" in all the files.
(like ... extern CString szRegPath). Hope this helps.
Pls let us know your status.

I will try this and definitely write back
Thank you so much

extern CString strGlobal = "Initialization Value";
extern CString strGlobal;
AfxMessageBox(strGlobal);
This gives me an error telling one unresolved external symbol

You got it backwards.
Put this in exactly ONE source file, your definition of the global variable:
extern CString strGlobal = "Initialization Value";
Put this in the header file, included by all source files that need access to the variable:
extern CString strGlobal;
That should work.
Marriage slows down your coding, a baby slows it down even more!

I am still not getting it 
Please show me in stdafx.h what i should put, in MySample.cpp and MySample.h what I should put? There are about 10 files, say MySample2.h, MySample2.cpp, etc.. in those what I should put? Show me the code please. I have never done this before. Sorry if I am troubling too much.
