Unused pointers should always be set to NULL, and checked for NULL before use. Also, ::IsWindow will tell you if a pointer is a valid window ( which a dialog is ). Finally, show and hide your modeless dialogs so the pointer does not change, rather than destroying and recreating them.

i am confused. 
can you give me an example of it
(They can just hold pointers to each other, provided by the host window),
where also the pointers are adjusted to zero?
thank you very much

In the constructor.
MyDialog1::MyDialog1()
{
pDialog2 = NULL;
}
Then presumably the main window when it creates dialog2, also passes the pointer to dialog1. In dialog1, you do this
{
if (pDialog2 && ::IsWindow(pDialog2))
pDialog2->SomeMethod(nSomeInt);
}
Finally, when the main program wants to get rid of a window, it calls ShowWindow(SW_HIDE); and when it wants to show it does this
if (m_pDialog1)
m_pDialog1->ShowWindow(SW_SHOW);
else
{
// Create the dialog
}

Which libraries do I need to used TCP/IP protocal in Visual C++ 6.0? 
|
|
|
|
|
What do you mean?
What lib-files?
Ws2_32.lib but you can read all about that in MSDN...

Do you use Winsock or Winsock2?
winsock.h
winsock2.h
ws2_32.lib

Tip: You should probably use the WinSock 2 library. If so, include <winsock2.h> before including <windows.h>. That way, it won't use the WinSock 1 definitions, besides, it in turn includes <windows.h> itself.
Don't forget to add ws2_32.lib to your imports in your settings so your app will link to the dll imports.

In complex number class, can I be able to just change the value Real or Imaginary?

No, you can't directly change the parts. You must use an assignment, e.g.
std::complex<double> c(1.0, 2.0);
...
c = std::complex<double>(c.real(), 3.7);

Hi
I'm writing COM add-in to MsProject2000. The problem is that using Project object I cannot change cursor that appear in MsProject app. I tried to change the cursor by WinAPI (unfortunately in this case CWaitCursor can't be used) calls but I failed. Is this possible to change cursor in MsProject by executing some code from my add-in?

I may be wasting your time, but YOU are wasting the time of everyone here.
You don't react in an adult manner. Come with accurate questions, and we are ready to take our time to answer you.
Other than that, improve your english. We cannot understand you.

if u don't understand the Q, go back to read it again, i think u understand now.
if u even don't know vc menu is different from normal menu, as i said: u are very poor.
go back read all replies one by one, who is in adult manner?
i post the Q for my job, not for kidding.
if u think replies are in adult manner, here may be an adult club.
i am waiting for help (from top c++ programmers, not at ur poor level), but when i read replies in words of ur adult club, i am angry.
don't type anything on the forum except u sure u can help.
see, one funny reply is:
HAHAHAHHAHAHHAHHAHAHHAHAHHAH!!!!!!!

This we all probably agree on. But the initial question at the start of this thread was incredibly vague. You have since provided enough information about what you want to achieve.
Some of the replies to you were just in response to the vagueness of your question. The more information that you provide in the question the better. Look back at your question and assume you didn't know what you were asking about and see whether it makes sense to you.
As for Christians HAHAHAHHAHA. A bit out of order, but he is a very good c++ programmer. He also has had experience in this area as he did something along these lines for the XT toolkit at www.codejock.com, but which they didn't use in the end. (which is a shame, as I use the XT toolkit in my projects).
You wanted to know about drag n drop / tear off buttons / menu items etc.
This is a very big and complex topic. There used to be an article on it here at CP (BCGLibrary), but which has since gone commercial and the code is no longer available. The best bet would be to start from one of the owner drawn menu articles and try and add the required functionality from there, but its a big and difficult task.
As I say, this is not a samll problem it could take months to get something working, or you could use any of the commercial libraries that provide this, but they cost $/£'s
You can find advertisements for them here at CP.
Good luck.

don't show me ur poor knowledge again: vc menu is based on CControlBar, not such owner-draw as u guess.
don't scare urself say "This is a very big and complex topic", i work on it for only one day, basically it works already.
don't tell me "Christians is a very good c++ programmer", i checked his replies yesterday, most of them are guesses plus mistakes, definitely not from an experenced c++ place.
don't sound as a teacher on this forum, u don't know who u r talking with, u never realize that a lots of people here are much better than u.
