CoIntialize() is used to Initializes the COM library. That is if you are using any com library functions you do this. But _Module is not created with CoCreateInstance() or something like that. So I don understand the need of CoInitialize() in this scenario.

Hi,
I need some advice/help in writing a program to parse XML file (using DOM) and returning element inside a particular tag. So if I select a tag identified by its tag value, it should give me the element inside that tag.
Appreciate all your help.
Thank you
Ray

 i have been Written a Hanoi's tower that base on GUI using VC++ development.
Now, the program has a few bugs, but i havn't know where that errors are. soon i will revise these errors, maybe the program is fun and u can take the Hanoi's tower to study recursived program with C or C++, For the moment, the source codes can't opening line but that will be quickly, [There ]is to download the program demostration.
Any proposes as follow comments.

Hi All,
I am facing problem of handle leak in my Application.
While using AfxBegin thread creating a worker thread in suspended mode and then resuming the thread using resumethread.
During above process 7 Handles are getting created but when I am exactly closing the thread using PostThreadMessage(WM_QUIT, NULL, NULL) only 5 handles are getting closed. Two handles are not being closed.
The details is like This:
m_pControlThread = AfxBeginThread (
ControlThreadLoop,
( LPVOID )this, THREAD_PRIORITY_NORMAL,
0, CREATE_SUSPENDED
);
m_pControlThread->ResumeThread();
from above 7 handles are getting opened.
In Destructor Closing like this:
if (m_pControlThread)
{
m_pControlThread->PostThreadMessage(WM_QUIT, NULL, NULL);
WaitForSingleObject( m_pControlThread->m_hThread,
_MESSAGE_TIMEOUT );
delete m_pControlThread;
}
Here only 5 Handles are getting closed...
Where remaining 2 handles are missing .... I am not getting any Idea..
Please suggest..
Thanks,
Jokhan

That could be normal behaviour. Windows likes to keep some handles around to be reused later. The way to check if this is the case is to run and stop your thread multiple times. If the total handle count does not keep climbing you are ok, if it does climb you have a problem.
ie: handle count is 0...7...2...7...2...7...2...7... etc OK
" " " 0...7...2...9...4...11...6...etc Error

Hello Arends,
Thanks for your suggestion.
You are right but In my case the total ( after few iteration of start and stop) number of handles are increasing. And it is 2 handles per iteration.
And As I have written in posting: while quiting the thread only 5 handles are getting closed though each time 7 handles are getting opened.
Please suggest!!
Thanks,
Jokhan

i trying to disable mouse wheel in comboBox , i try to find this option in propertise but i dont find this option .
In comboBOx control i also can`t find this option.
Someone can Help me ??
How can i do it ??

A very nasty trick  would be to derive a class from the combobox control, use it in place of your combobox control, capture the mousewheel messages WM_MOUSEWHEEL and then don't forward them to the base class...

your global variables are not initialized when you initialize your arrays. Then your arrays are initialized on the stack before your main function is called. Inside of your code, you never assign any values to the arrays afterwards.
What you should do, is simply move your array initialization after you call all of your functions a-h, then values will be assigned into your arrays.
Good luck

New Problem: Now I'm doing the multiplication, where I'm trying to multiply the arrays in this order:

You can use 60 degrees for theta and phi, for check, since cos(60) = 0.5, sin(60) = 0.866....

Thanks in advance.

when you are create new WIN32 Console Application project , on step 1 you can choose "An application suppurt MFC" from options.
But you can also include class <afx.h> that support CString.
