hello,
is there a simple way, how different dialogues can be linked in a program?

Linked how ? Talk to one another ? I presume they are modeless ? They can just hold pointers to each other, provided by the host window. If that's not what you want, explain further what you're trying to do, so we can help.

this i still have, when the first dialog is linked with the second dialog, everything is fine, but when the first is linked with the second and third dialog, the program is terminated.
what´s wrong?

Why do you have three dialogs up ?

1. It's probable that a pointer you're passing around is becoming invalid for some reason.
2. You haven't posted any code, which makes it hard to do more than guess.

I believe that the first point is my problem.I think, I must give a value to the pointers (if they be produced). But how? (I´m sorry, but I have the code not here)

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
Kuphryn

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?
