Well not compared to chewing gum 
ya my mistake i was expecting the message map to be like this:-
ON_NOTIFY( HDN_ITEMCLICK, 0, OnHeaderClick)
but it will be like this i guess
ON_NOTIFY( HDN_ITEMCLICK, IDC_LIST, OnHeaderClick)

are there any available comparison functions just for a simple list control for a clicked-on header, to be passed to SortItem?

Other than the one I already provided? It doesn't get much simpler.

are you referring to the CompareFunction in the article you sent?
in that case, would I have to make use of "GetItemText" to fill in the "items" in CompareFunction? i'm just not sure how to implement this with a list of unknown quantity of items..

No. You would cast lParam1 and lParam2 to the appropriate pointer value (the pointer value used with SetItemData()).

I am very sorry I do not understand.
I do not make use of SetItemData().
All I have is my list control where I have a few InsertColumn()s and SetItemText() accordingly.
When you tell me to cast these as pointers
int CALLBACK CompareFunction(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
...pointing to what exactly?

Have you tried the sample code in the link David Crow gave you?
They probably point to either an LVITEM or some MFC wrapper class. This information was obtained by reading the docs for the CListCtrl class; you get there by clicking up from DC's link.

But you must, if SortItems() is to be used, as it internally calls GetItemData().

You'll also need to use InsertItem().

Whatever pointer value you used with SetItemData().

oh I actually did use InsertItem()
when you say to cast lParam1 and lParam2 to where I must have pointed with SetItemData, do I set them to the same pointer value? what makes param1 and param2 unique?

Do you not understand that sort will be called from inside a sorting algorithm and you don't need to be concerned with the quantity of items?

I was wondering how other programs store the code and documentation in order to reuse it someday? I have a file/folder structure that has information stored in it but is getting a little out of control? I was wondering how other programmers store their code and documentation for future use? Does anyone use special code management software?

Every where I have worked we used Source Code Control software. CVS, PVCS and VSS.

Ok, Maybe I didnt write my question right. I am not talking about source control. I do not need to keep track of changes because I always want the newest version.
Example: I have ProjectA, ProjectB, ProjectC. Function1 and Function2 are used in ProjectA and ProjectB. I want to save those functions somewhere so that later on (ProjectF) if those functions are needed I dont have to go "remember" that the functions are in ProjectA and ProjectB. I would like to go out to a file structure or something where that function is stored and then put it into ProjectD.
You kind of see where I am going with this?
I would like to organize a file/folder structure in a way to maximize an ease of finding code (functions,classes,dlls,libraries,sample projects,add-ins,etc).
My first question is I wonder how other programmers store their code in a file/folder structure (If so what does their C++ folder structure look like), or do they use a special program.
I would also like to keep track of the DOxygen code assocated with the source code.

I believe so and it still sounds like Source Code Control.

A) File structure will not hold a "function" it will hold "files" so you are still referring to source code.
B) Source control systems provide sharing of files across projects so they manage that part for you.
chris175 wrote: because I always want the newest version.
Wow, have you never introduced new code and then decided you didn't want to keep it? Happens all the time to me then all I have to do is "undo the checkout" and I am back to where I started with a single mouse click!
Have you never made a change that introduced a "bug"? Source Control Systems provide "differencing" which simplifies finding "what" changed that might help "find the bug".
I see nothing in what you posted that would not be solved using Source Code Control system. Personally I never develop anything without using source control.

I have introduced new code and then decided I didn't want to keep it. Maybe more examples may help understand...
GetDefaultPrinter.txt
-----------------
Setup:
-----------------
- Add an include directory, C:\Program Files\Microsoft SDK\include
- Add a link to Winspool.lib
-----------------
DOxygen File:
-----------------
-----------------
.h File:
-----------------
bool GetCurrentDefaultPrinter(std::string& s_printer_name);
-----------------
.cpp File:
-----------------
#include "Winspool.h"
bool GetCurrentDefaultPrinter(std::string& s_printer_name)
{
s_printer_name = "";
CPrintDialog cpd(FALSE);
if(!cpd.GetDefaults())
{
return false;
}
s_printer_name = cpd.GetDeviceName();
return true;
}
stdstring - Is Digits.txt
-----------------
DOxygen File:
-----------------
-----------------
.h File:
-----------------
bool Is_String_Digits(const std::string& s_digits);
-----------------
.cpp File:
-----------------
bool Is_String_Digits(const std::string& s_digits)
{
if (s_digits.length() == 0)
return false;
for (int i = 0; i < s_digits.length(); i++)
{
if (!isdigit(s_digits[i]))
return false;
}
return true;
}
I am not trying to argue with you that putting these files into source control is a bad idea. You could if you want to. I just choose not to. What I want to get at is how all these different files are organized. What type of file structure? Do you use any software (besides version control) to accomplish this?

I haven't looked into it myself. Seems to me from your replies that you are looking for something that manages a snippets library or code repository type of thing.
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

I must say C# is a 100 times easier than C++. I started my career with C++ and am very thankful I did so. After a pretty extensive knowledge of C++, I was forced to learn C# (work related). After programming in C++ for around 2-3 years I moved over to C#. In about a month of programming in C# I was nearly an expert....with the basics at least...because it is so incredible easy after C++ (especially with the tab control). The things you dont have to worry about (deleting stuff). You really appreciate how easy custom control can be made and the reuse of code. Simple things no longer take forever to figure out. Simple things no longer have 5 hidden steps inbetween that noone talks about. (Like for instance finding if the current user is an administrator. I search on the net for 4-5 hours and finally found 1 web site that shows how to do it. In C++ there is about 5 to 6 special functions for this and they all have funky names. In C# I think there is a special namespace for this and its so self explanitory.)
Anyway if you are looking for easy I would say C#.

If you want to be able to look at any language and see what is going on even without knowing that language, learn C++. It will take you longer to learn than Basic, C#, or Java, but once you understand it, you can look at anything else and work well in it with little to no learning curve.
Also, is you are planning to go to college and work towards a computer science/computer engineering degree, most of your programming classes will likely be using C++.

All Java at UW Madison. People come out of school not knowing how to really program. I think Java is a fine second or third language, but not a fine first one

My opinion of Java is that it is a language designed for lazy programmers. Its almost ironic at the moment since the project I'm on at work requires a heafty amount of java programming
If you learn C++ first (and well), you never need to pick up a Java programming book (just need to look at the documentation on java.sun.com for reference). Going that route also teaches you one very important thing: OO programming is useful, but many times it gets in the way of what you really want to do and a functional or structural language would better serve the purpose. This is one of the reasons why C/C++ is far more versatile than Java, Basic, C#, etc.
