That can not work. This is because a map is allocates memory on the heap which does not work using shared data segments because the heap is not part of the shared data segment. You need to use a structure that at compile time allocates the maximum storage necessary and does this in the shared data segment.

Or create a memory mapped file and don't use a shared data segment at all...
Any sufficiently gross incompetence is nearly indistinguishable from malice.

Hi,
I want to create vertical tab pages, with bitmap images on the title of each property page, using CPropertyPage. Can anyone tell me how to do this? I tried to paint on the title of the page, but do not know from which place should I do this.

By 'title' do you mean the tab that you click on to select the page?
If so then you can do this from the CPropertySheet class. Use CPropertySheet::GetTabControl() to get a pointer to the tab control, you can then use the CTabCtrl member functions to do what you want, including custom drawing the tabs.
You may be right
I may be crazy

I think this is a typo in your post but this is objbase.h
Anyway, post the line of code where you call it, it's probably a typo.

Inside the a thread
BOOL CClientThread::InitInstance()
{
//CoInitialize(NULL);
CoInitializeEx(NULL,COINIT_MULTITHREADED);
m_TimeLock.Lock();
m_timeLastAction = CTime::GetCurrentTime();
m_TimeLock.Unlock();
// Attach the socket handle to a CSocket object.
// This makes sure that the socket notifications are sent to this thread.
m_ClientSocket.Attach(m_hSocket);
m_ClientSocket.m_pThread = this;

And what is your exact include directive ?
|
|
|
|

In Stdafx.h
#define _WIN32_WINNT 0x0400
#define _ATL_FREE_THREADED
#include <objbase.h>

i have tried to search the answer myself, and found an beginner's article "MFC under the hood" by Nishant Sivakumar. He explained Winmain() was defined in appmodul.cpp which can find in MFC\SRC directory :
extern "C" int WINAPI
_tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPTSTR lpCmdLine, int nCmdShow)
{
// call shared/exported WinMain
return AfxWinMain(hInstance, hPrevInstance, lpCmdLine, nCmdShow);
}
i understand that winmain() simply call AfxWinMain, but the code above is _tWinMain() not usual Winmain(). What is _tWinMain(), and where is Winmain()? help me please.

_tWinMain is probably the TCHAR version of WinMain() but why would anyone care? Why do you think you need to know "where it is"?

When you are used to one language, in order to learn a second you need to know how it compares and how it works. The English word brother has three translations in Chinese, what do I care what the other two are when I only know one? I will tell you after I go and insult somebody!

Ok... MFC is NOT a language.  but whatever I was just wondering.

I did not imply that MFC was a language, and I appologise if you missunderstood. What I meant to say is somebody who is used to coding in C, then start learning the MFC side of C++, is going to be very confused. MFC does a lot of work behind the scenes, many of the functions we have come to learn and accept are no longer required. In my opinion, in order to start learning MFC 'from another language', you need to know what the 'translations' are, or what functions an MFC method is actually calling.

i don't really agree with your demonstration here.
MFC hides the main() function, and if it does, it is certainly for good reasons.
you don't have to know "where is" main() nor "what it does". you only have to know "where to start when using MFC"...

That is probably true. And I would also go as far as saying that if you are using MFC then you have no need to access the main() function. But...
toxcct wrote: you don't have to know "where is" main() nor "what it does". you only have to know "where to start when using MFC"...
... if you already know what main() does, how it's used and what exactly it's purpose is. Infact if you have come to believe (not quite true I know) that every program must have a main() fuction, then you start with MFC, aren't you going to wonder WTF?
If you are starting out with MFC and C++ as a first language, then you don't need to know nor will you care. But when it's a second language you will start translating what you know into what you are learning.
