Hi,
I am a c# programmer. I got an application in c++, i need to integrate that to my application in c#.net. I dont know c++ programing, not even to run.
How can i use the c++ application in c#?
Thankyou
YPKI

Are you wanting to convert your C++ code to C#, or are you wanting to run an application from within C#?

For the latter, try ShellExecute() or CreateProcess().

Is there any difference between
auto_ptr<<foo>> p;
...
p = auto_ptr<<foo>>(new foo);
and
auto_ptr<<foo>> p;
...
p = new foo;
I saw the first form in examples and wondered why it was being used.

are you sure. that you'd able to do this? I think compiler will throw error.
You've to be careful about auto_ptrs unusual characteristic. Copying them them to null, and the copying pointer assumes sole ownership of the resource
See the example demonstrate this issue from Effective C++ 3rd Ed.
std::auto_ptr<Investment>
pInv1(createInvestment());
std::auto_ptr<Investment> pInv2(pInv1);
pInv1 = pInv2;
// object, and pInv2 is null

Hi,
Can u pls suggest me any book to start with for MFC in VS2003 and even im new to vc++..

Hi,
Programming Windows with MFC[^] is a great book, written by Jeff Prosise.
Legend says that one starts with Programming Windows with C++ and work your way up through frameworks and libraries. If you'd like to pursue that path, you could start with Programming Windows[^] by Charles Petzold.
Of course, you would be expected to be able to do C/C++ programming well before you touch any of these.
Happy learning.

I learnt from an earlier version of this one[^].
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
|
|

|

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(); }
