The name (Programming with Microsoft Visual C++ .NET) of this version looks like it would explain managed stuff too.
I'm not against managed code, but I don't like the idea of mixing up managed code with good old native C++. It's like eating garlic with ice cream.

That was actually the name of the product - remember it used to be Visual Studio .NET rather than just plain Visual Studio? 5 out of the 35 chapters cover .NET - the rest are plain Visual C++ and MFC (I know because it's on Safari & I can see it ).

Yes, that was very much what I was talking about. They can please publish another book to explain all the C++/CLI stuff instead of dedicating 5 chapters to show how .NET "fits in". But I see this is happening with a lot of books these days.
I can't wait for X86 .NET.

Please read the posting guidelines. I don't think anybody will want to read all your source code.
As far as I understood, you want to pass a variable from one dialog to another one. Is that correct ? If yes, then take a look at this article[^]

You could pass the value in the constructor:
CMyModeless2::CMyModeless2(CView* pView, CString sPP)
{
m_sPP_modeless = sPP;
m_pView = pView;
}

I am in the middle of porting one of my C++ project which is using old iostream (shipped with VC6.0) into new iostream implemented in stlport version 5.2
I found that some of the stream related methods are not available in the new iostream class.
The compiler gives me error for the following methods
streambuf::allocate()
streambuf::doallocate()
streambuf::blen()
ostream::osfx()
ostream::opfx()
streambuf::base()
streambuf::ebuf()
streambuf::setb()
Am I missing something?
Are there any equivalent methods available in new iostream library?
How can I substitute these functions when I port into new stlport/VS2008 iostream?
Thanks in advance
cheers

streambuf::doallocate()

streambuf::base()
streambuf::ebuf()
streambuf::setb()
These all refer to the 'reserve area' of the pre-standard IOStreams streambuf. The standard basic_streambuf doesn't have this concept at all (I guess they decided it was better for that concept not to exist in an abstract stream buffer). This post[^], however, gives a suggestion for a possible solution.
Varghese Paul M wrote: ostream::osfx()
ostream::opfx()
These were functions that ran before (opfx) and after (osfx) every output operation. They've been replaced by the sentry nested class, so rather than this:
if (os.opfx()) { os.do_something(); }
os.osfx();
you have this
std::ostream::sentry se(os);
if (se) { os.do_something(); }

hello:
I want to display the diagram charted by visio with mfc, and I can contorl the color of shapes at any time.
But I don't know how to bring about.
At first, I realize it by visio drawing control, but the program is started up very slowly, and the shape aren't zoomed with the zooming windows.
Now I don't do it, can you have another way to realize it expect the way using "visio drawing control"?
If you know, help me please!
thank you!

Hi there.
I have an application ofwhich threads concurrently act on multiple instances of a certain class called CChannel.
CChannel has a method called ::Send which must be protected. For that end I put in a place a Critical section as a data member of CChannel then I call EnterCriticalSection and LeaveCriticalSecion within ::Send. I avoided to use a global critical
section for performance reasons : indeed I do'nt want to have a blocking scenario when thwo threads call ::Send on two different instances.
At some point of time, I need to delete a Channel object. Since threads hold references to the pointer addresses, the application can easily crash if one thread tries to use a certain address pointing to an object that has been deleted by another thread.
To overcome this, instead of communicating addresses, rather I communicate access numbers. these number serv as a key for a map that stores context structures containing the actual addresses and also the per-instance CriticalSection. So the CriticalSection which used to be a data member of Channel is now out of the class (I will be able to delete a Channel object, but still use its acorresponding CriticalSection)
Here my solution, I am not confident, I think it works, but anyway I will be happy to be helped with a much more solid solution.
<pre>//This is the wrapper structure. it contains the criticalsection, the pointer to CChanel
typedef struct ChannelContext
{
CChannel* pChannel;
CCriticalSection cs;
} ChannelContext;
typedef std::map<UINT,ChannelContext*> channelMapT;
channelMapT channelMap;
CCriticalSection csMap; //(used to protect the map).
//The following two function can be called without problem by any thread :
//This function is called by a thread when it needs to act on a certain CChannel.
//it is meant to provide safe access to the CChanell. the calling thread only needs to check if the retunred
//address is not null, then consume pContext->pChannel, then when it finishes its job with the Channel is calls
//pContext->LeaveCriticalSection(&pContext->cs).
ChannelContext* requireChannelByKey(UINT accessKey)
{
EnterCriticalSection(&csMap);
channelMapT::iterator myIt=channelMap.find(accessKey);
if(myIt!=channelMap.end())
{
ChannelContext* pContext=myIt->second;
EnterCriticalSection(&pContext->cs);
LeaveCriticalSection(&csMap);
return pContext;
}
LeaveCriticalSection(&csMap);
return NULL;
}
//Function to delete an object.
void deleteChannel(UINT accessKey)
{
EnterCriticalSection(&csMap);
channelMapT::iterator myIt=channelMap.find(accessKey);
if(myIt!=channelMap.end())
{
ChannelContext* pContext=myIt->second;
EnterCriticalSection(&pContext->cs);
//Delete the entry.
channelMap.erase(myIt);
delete pContext->pChannel;
LeaveCriticalSection(&pContext->cs);
delete pContext;
}
LeaveCriticalSection(&csMap);
}</pre>
Thank you in advance. Note, if someone have ideas how Windows manages its internal structure then please enlignten me.
I think that HANDLE just act like the accessKey : it hides the pointer addresss. But what about synchrnoization ?
