Thanks a bunch for the post. I was having trouble with the fact that if a random point was greater than the given point the point would be negative when I took the difference. I forgot all about the euclidian distance formula thanks a ton! I'll try to get the test program working now!
Thanks again,

I need to figure out via a hwnd if the hwnd I have is a common dialog box. Is there a style, class, etc associated with common dialog boxes? I am only interested in the open and close dialog boxes. What is the best way to do this?
Thanks

Using Spy++, it appears to me that there is no special class given to the Open and Save Dialog boxes, they are declared as the regular #32770 class, which is the identifier for the dialog class.
There may be some other trick that you can employ, like test the title or something, but this will not be guaranteed to work, especially if you are testing in someone elses application.

Does any one know a good article (preferably with source) about creating and reading group policies ?

Joaquín and Christian...my appologies for asking a rtti question again, but I still don't have quite enough experience with it to fully understand whats going on despite numerous teaching attempts from both of you. 
Anyways.
I have an dynamic array of CWnd's which I would like to be able to act, look and feel like CButton, CEdit, CComboBox etc...
m_pControls = new CWnd[m_nControls];
dynamic_cast< CButton >(m_pControls[0]).Create(this, CRect(0,0,100, 20));
Someone wanna show how I do this properly..?
Thanx

Well, I think you have some misunderstandings about what kind of things one is supposed to do with dynamic_cast.
First of all, dynamic_cast only works for pointers or references. Your last sentence cannot work because you are tyring to use it to cast to CButton instead of CButton *. There are a lot of other reasons why it won't work, however.
Suppose you have a inheritance hierarchy like this
A
|
-------
| | |
B C D Now you're given a pointer to A and you want to know whether the object pointed to is really a B:
A * pA;
...
B * pB=dynamic_cast<B *>(pA); At this point, if pA was actually pointing to a B (which is legitimate, as B derives from A), pB will be non-null. Otherwise, pB is null, menaing that pA points to a C, a D or something else. In this way, dynamic_cast lets you peep into the actual nature of an object referred to from its base class. What dynamic_cast does not do is create objects of derived classes on demand, as your code seems to assume. Hope this helped clariy things a bit more.

Ummm...sorta...RTTI is proving to be the most difficult thing for me to understand fully. I'll probably have to hit the books again for a while.
I did however find another way around my problem, which actually is easier and less overhead. I hate it when I do that, try to solve a simple problem with a difficult solution. One day i'll learn.
Thanx again

Is there any way to change this rule and it increaze when it goes up?

I have created a Multiple Documents MFC project, using Internet Explorer Rebars for my toolbars instead of normal MFC toolbar.
When I put a control in my IDR_MAINFRAME dialog (the dialog bar), the control remains disabled even if I associated it with a member function for the message BN_CLICKED.
How can I do to enable my control?

- Put in an ON_UPDATE_COMMAND_UI() handler for it.
- Make sure the ON_UPDATE_COMMAND_UI() handler gets called - it must be in the toolbar OWNER window class.
Good Luck!

How would I go about creating a triple pane setup using splitters...?
Would I create a split window normally, then in the OnCreateClient of one of the child splits repeat the process...?

I'm aware of the triple pane CSplitterWndEx 'T' control, but it's not what I need unfortunately.
Thanx anyways!

The CSplitterWndEx class can create virtually any splitter layout you wish. Want do you want done differently?

I've used that class before, it's a great time saver!
But it's to much extra overhead and i'm curious as to what the best approach would be, without a third party class.

You can split the main frame into two views. Then split the right split into two views to get an OE like 3-pane view.
I used to do it slightly different for some time.
I used to split the main frame into two. The left split is a view and the right split is another frame window. This frame window, I again split into two
The difference is that now the splitters are distinct. Means there are two splitters. There is a slight difference in look and feel. Also in resizing.

Does anyone know a REALLY GOOD class tutorial???
Like one that explains everything about static and virtual and public and private and the passing of variables and how to arrange it all, and perhaps the most important the communication between one class and your main application's class.
I just dont understand much of it (i've been having a tendancy of making everything global lately, which really isn't a solution for me...)

Hi Kuniva. A good book for starters (though not exactly a tutorial, it's pretty long) is Bruce Eckel's Thinking in C++, that you can download from the net for free. Also, a very good FAQ about C++ is Marshall Cline's C++ FAQ Lite. If you invest some time reading these two resources and practising a bit I'm sure you'll get much more profficient at C++ in a matter of weeks. Good luck.

You are welcome. I wish there were places like this when I was your age and struggling with BASIC and Z80 assembler.
I hope you'll strike back with some fabulous article featuring that Winsock class of yours once it's up and running, won't you?

hey Joaquin,
lol, well actually... i'm not writing a winsock class, and if i have to read 878 pages first to learn OOP it wont be for this year lol.
I'm actually writing a class that will serve as a chat engine for www.spinchat.com. I always go to this chat and it's easy to write Bots for it because it works with non-encrypted text commands 
I already started writing two bots but never used classes and that took too long so now i'm trying to write a class i can just reuse everytime.
I don't know if i'll be posting it on the Codeproject because others also made bots but in Delphi and VB so i wanted to do it better but if i post the class then they'll be able to write one as easily as in VB (probably even easier) so... i'm not sure, maybe i'll leave a few 'special' functions out so i still have something to call my own  . Anyways, i'm sure i'll be writing more articles and contribute to the codeproject throughout my findings.
