Shouldn't this be:

{
public:
friend ostream& operator<<( ostream&, const Tkontaktai& );
};
ostream& operator<<( ostream &os, const Tkontaktai &duom )
{
return os << duom.vardas << " " << duom.tel << endl;

Thanks, you are right! I was adding operator overloading in the wrong class...

There's no rule that states an application needs to make a registry entry when it is installed.
There may be a way, maybe not - this is vendor-specific.

Hi,
if there is a registry entry you can find it, if there is a Start-Menu entry you can use it too. If not... you have problems  But there is still ways to know it, the problem is they are difficult

Hi,
I want to use a common Database for my Application installed on different Systems in Network. I am using ODBC Connection for Database access through my Application ( application developed in VC++ ).
What should I do for this? ( What is my applicaiton is developed in C# 2005? )

If the database ODBC driver supports network connections then you should be able to adjust
your connection strings to connect to the database over a network.

I am currently working in a office as network supervisor. In office, we are sharing one internet connection. In the meantime, out internet is very much slow due to some virus/Trojan attacked some of our computers.
For monitoring the our computers, I want to make a program in VB6. I need help for making a DLL (activeX if possible) for following task.
-- can detect network card(s).
-- can detect internet request on Main Computer (from which, internet is shared)
-- can show client IP/MAC address.
-- can drop/pass the request.
-- can redirect to another destination in case of porn site.

I think that detecting internet request from other computers to one computer needs NDIS Hook system and this is possible only from C/C++. But I don't know C/C++.

When I try to start my application developed in VC++ .Net 2003 in Vista System,
an error message saying "The application failed to initialize properly (0xc0000142). Click on OK
to terminate the application." is displayed and I cannot run in both mode(administrator/compatibility).
My application need some DLL files in the same folder if DirectX is not installed.
Any help would be greatly appreciated!!

I hope you have got the dwError from the API GetLastError.
You should call the GetLastError function immediately when a function's return value indicates that such a call will return useful data.

Paresh.

Jes I do. I Call GetLastError immediately
if (!theApp.m_pConn->SetCurrentDirectory(voxftpdir))<br />
{<br />
CString str;<br />
err=GetLastError();<br />
...<br />
