Does anyone know of a class that parses C/C++ code (like the classview tree in VS)?

Parse how? You mean a lexer?

I'm not sure what it's called else I would have googled it.... I want to extract structs, typedefs, classes, externs, globals, etc. the same way the class-view tree does in Visual Studio. I don't know what the act of doing such is called, other than "parsing".

Man, that's not a trivial thing to do.
To start you'll need a lexer -- takes text and determines if it's valid C++. This alone takes some doing, cause C++ isn't the most syntactically pretty language around. Don't try and do it yourself or you'll die of old age; instead, write a grammer and lean on a lexer.
Then you'll need a parser; it takes the output from a lexer and typically gives you a structure tree.
Grab the dragon book and read about compiler construction; you're building the first two or three stages of one.
For available tools, try lex, yacc, and bison.

Parsing C++ is insanely difficult.
You could try hacking the gcc parser (hard) or maybe take a look at this[^]. It's a long time since I looked at PCCTS but IIRC, it seemed to work 
I use CCCC[^] for metrics sometimes and that has a parser as well.

Hello,
I have a list control item with a given amount of columns and respective headers. I would now like to add some sorting functionality, where, upon clicking the header of the respective column, it sorts alphabetically. Are there any functions to accomplish this?
|
|
|
|
|
BOOL SortItems(<br />
PFNLVCOMPARE pfnCompare,<br />
DWORD_PTR dwData <br />
);

You'll have to create a compare function to handle how it will sort the items, but after that you can just call SortItems. See the MSDN documentation for details and an example.

okay but what action item will take care of the header clicking functionality, because from there I can call sorting method.
|

In your CListView/CListCtrl-derived class, provide a handler for the HDN_ITEMCLICK notification. Call the SortItems() method from there. See here for more.

Well to first add the notification for HDN_ITEMCLICK is tough:-
why because the on notify macro is as follows
ON_NOTIFY( wNotifyCode, id, memberFxn ) and the id of the header control is zero unless explicitly set .

Compared to what, chewing gum? It gets added to the message map just like any other. How's that tough?

Yeah, so?
FarPointer wrote: ...the id of the header control is zero unless explicitly set .
Of course it's zero, and has been since the control's inception. Why would it need to be anything else?

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?
