serch for Port Scanner On CP ,you will many good Code for that.

An idea Behind it is.
create a socket application and connect each and every port
on local system.like this.

<br />
  CSocket a;<br />
  a.Create();<br />
  CUintArray b;<br />
  for(int i=0;i<=1024;i++)<br />
  {<br />
       if(a.Connect("127.0.0.1",i)==TRUE)<br />
        {<br />
         b.Add(i);<br />
         a.close();<br />
        }<br />
       a.close();<br />
    ::Sleep(1000);//wait for i sec<br />
}

and CUIntArray b contain all open port on your system

I have never tried it, but most Intel and AMD CPU's have a instruction called CPUID.

Search google for cpuid and "source code"

I have appended some elements to my root element using appendchild. Even then getElementsByTagName() returns nothing. What should be done. Here's the code.

pXMLRoot = pXMLDocument->createElement("CDLAYOUT");
pXMLDocument->appendChild(pXMLRoot);
pFamilyNode = pXMLDocument->createElement("FAMILY");
pXMLRoot->appendChild(pFamilyNode);
pFamilyNode->Puttext("tiger");
pOSNode = pXMLDocument->createElement("OS");
pXMLRoot->appendChild(pOSNode);
pOSNode->Puttext("Win2k");

AfxMessageBox(pXMLDocument->xml);

set = pXMLDocument->getElementsByTagName("*");

Thanks in advance

A lot would depend on the hardware you are planning to use.

You might want to search for VOIP (Voice over IP).

You can't connect a IP connection phone call to a PST standard phone without hardware in the middle to do the swapping.

You would need to find a phone provider who could do that for you. You won't be able to do it with a standard ADSL modem. You can do IP to IP fairly easy but not IP to PST.

Hello,

I am trying to manage IP, Masque, DNS, and DHCP in C++ and I can't find a correct method to manage it.

I have developed a programme using Windows Registers but the programme doesn't work on all Windows XP computers sniff.

Can anyone tell me the best method to manage TCP/IP parameters for Win 98 to XP computers???

Thanks for your help.

Hi,

I tried using the code below but the value turns to 'NULL' on the next loop...Pls help.

CString MyString = "ABCDEF";
char * szMyString = (char *) (LPCTSTR) MyString;

maybe you should write what you want to do...
the code looks, like you are going to make
a mistake...

Two options are

// Recognising that LPCTSTR is const TCHAR *
CString MyString("ABCDEF");
LPCTSTR szMyString = MyString;

or

CString MyString( "ABCDEF" );
LPTSTR szMyString = new TCHAR[MyString.GetLength()+1];
_tcscpy(szMyString, MyString);

'G'

//---------------------------------------------------------------------------------------------------//
//check if the application is already running...
bool bAlreadyRunning;
HANDLE hMutexOneInstance = CreateMutex( NULL, TRUE, "Pointer to a null-terminated string specifying the name of the mutex object.");

bAlreadyRunning = ( GetLastError() == ERROR_ALREADY_EXISTS );

if ( hMutexOneInstance )
{
ReleaseMutex( hMutexOneInstance );
}

if ( bAlreadyRunning )
{
//AfxMessageBox("Application is already running");
return FALSE;
}
//---------------------------------------------------------------------------------------------------//

Include this code in the InitInstance of your app. This will do the trick for you.

Hi there guys,

I was wondering if there is a way of having ClassWizard manually going through a project's newly added source files (.cpp/.h) and recognise both the class(es) and their members?

Thanks a lot,
