Re: Frustrating new operator problem ian mariano31-Oct-02 12:27 ian mariano 31-Oct-02 12:27  You can enable the debug CRT checks for memory leaks[^], and some of the other Memory Dumping/checking stuff from there. Maybe that will help on why you're unable to allocate using new.

You might be over running an allocated memory region and thus trashing the memory manager. Tim Smith I'm going to patent thought. I have yet to see any prior art. dialogs Lucky200231-Oct-02 10:12 Lucky2002 31-Oct-02 10:12  hello, is there a simple way, how different dialogues can be linked in a program? lucky Re: dialogs Christian Graus31-Oct-02 10:25 Christian Graus 31-Oct-02 10:25  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.

Lucky2002 wrote: what´s wrong? 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.

But how? (I´m sorry, but I have the code not here) lucky Re: dialogs Christian Graus31-Oct-02 11:10 Christian Graus 31-Oct-02 11:10  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.

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 } Christian No offense, but I don't really want to encourage the creation of another VB developer. - Larry Antram 22 Oct 2002 Hey, at least Logo had, at it's inception, a mechanical turtle.

Re: TCP/IP Starting Point valikac31-Oct-02 8:05 valikac 31-Oct-02 8:05  Do you use Winsock or Winsock2? winsock.h winsock2.h ws2_32.lib Kuphryn Re: TCP/IP Starting Point ian mariano31-Oct-02 12:17 ian mariano 31-Oct-02 12:17  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.

Re: How do I create a CArray of complex numbers in VC++ markkuk31-Oct-02 23:58 markkuk 31-Oct-02 23:58  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); changing cursor mariuszpopiolek31-Oct-02 6:40 mariuszpopiolek 31-Oct-02 6:40  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?
