There isn't a CWinThread::Create method.
As about CWinThread::CreateThread method, it is defined in thrdcore.cpp (MFC sources) you may have a look at it.

Thankx this seems to be what I have been looking for a way to

point to Cwinthread to my own threadproc

in the example the derived thread CthreaEx sets m_pThreadParms which is a private member of the Base Class Cwinthread ??

I would like to suggest that you should do a sample application and start debug. Then you can "step into" the code and see yourself what code is being executed.

I think you've been searching to pass a thread function to CWinThread?
By any chance you aren't aware an AfxBeginThread(YourThreadFunc) call returns you a CWinThread?

Yes I know but its a plain CwinThread

I would like it to return My own Object Derived from CwinThread e.g.

e.g. as in the MSDN example

so that thread can have acess to my data members function as well as that of CWinThread

// ...
class CSockThread : public CWinThread
{
// ... Other function and member declarations
protected:
CSocket m_sConnected;
};

SOCKET hConnected;

BOOL CSockThread::InitInstance()
{
// Attach the socket object to the socket handle
// in the context of this thread.
m_sConnected.Attach(hConnected);

return TRUE;
}

// This listening socket has been constructed
// in the primary thread.
void CListeningSocket::OnAccept(int nErrorCode)
{
// This CSocket object is used just temporarily
// to accept the incoming connection.
CSocket sConnected;
Accept(sConnected);

// Detach the newly accepted socket and save
// the SOCKET handle.
hConnected = sConnected.Detach();

// After detaching it, it should no longer be
// used in the context of this thread.

// Start the other thread.
AfxBeginThread(RUNTIME_CLASS(CSockThread));
}

I am not major in Computer science or software!But I am interested in Programming.And I am study it by myself!I have already read a lot of book!But i am still feel that it not enough.In this term,I will try to make some 2D Games To test my level.
But any body can help me.What courses should i learn to become a good Programmer!for example "C++" or "C"!
Thanks in advance! Smile | :)

Indeed as others say, programming is like driving, you should read the books about it, but you won't learn it unless you do it and do it again and keep doing it for a long long time...

When you start thinking about building a career in computer science, don't put in a specific language in your mind. You should be strong in concepts. How an OS runs a process? How memory is used by a process (stack,heap), and some data strucures like linked lists, stack, queues, etc. Then I'd suggest you could start with C++ or C#. And it'd be time you would start understanding how a program is compiled,linked,executed. And before you try to make a 3D volume analysis algorithm,Or even a 2D game, I suggest you concentrate on the paraigms. Like OOAD. All the best know languages have adopted OOAD. So you need to be strong with the OO concepts. It doesnt make sense if you write a 2000 line C++ code without knowing OO. What students do is to write C code inside C++ and call it C++. After you become confortable with OOPS you may choose to work with C# or C++. In C# you can easily bring up colorful apps. In C++ little work around would be required. Then you'll have to learn the OS specific APIs to implement them in any language. Because if only you understand the APIs , you'll understand the frameworks around it. Like MFC on top of Win32.
So the road map is clear.
Round1.

HOW-STUFF-WORKS(BASIX)->OOAD(NOVICE)->C#,C++(HelloWorld)->WIN32APIs->MFC/Donet

Round2

HOW-STUFF-WORKS->OOAD->C#,C++(May be your 2D game)->WIN32APIs->MFC/Dotnet

Also when you learn to build programs using frameworks, you should also start learning Databases.

You might notice there's no much difference between Round1 & 2. But it will be totally different when you again take up the books and read. It won't stop with that. Everytime you read it again, you will get better meaning & understanding.

Finally, As you see, there's nothing called "VB" in the road map.

Also an important notice. I'm no expert. I'm someone swiming so hard in between round 2 & 3. Sigh | :sigh:

how to create XML file using MFC

Hi,
I am using one own function "XmlFileWriter".In that I want to create one
XML file.

I added following code to stdafx.h

#import <msxml.dll> named_guids 
using namespace MSXML;</msxml.dll>

And I have declared following smartpointers in XmlFileWriter.h file.

IXMLDOMDocumentPtr m_plDomDocument;
IXMLDOMElementPtr m_pDocRoot;

In my function I have written Initialization code

::CoInitialize(NULL);

HRESULT hr = m_plDomDocument.CreateInstance(CLSID_DOMDocument);
if (FAILED(hr))
{
 _com_error er(hr);
 AfxMessageBox(er.ErrorMessage());
 EndDialog(1);
}

It is giving Syntax errors 'IXMLDOMDocumentPtr' : ambiguous symbol
'IXMLDOMElementPtr' : ambiguous symbol

Can anyone suggest me how to do it.
