Hello Esteemed Developers
I am trying to develop basic TCP/IP Server-Client programs at the Visual C++ .NET, using Windows Forms Application(.NET) template. I coded the following code snippets

FORM1.
--------------------------------------------------------------------------------------------------------------------
public __gc class Form1 : public System::Windows::Forms::For

 ..
 public
          #define PORT 2222
          #define IP_Addr "127.0.0.1
          SOCKET ServerSocket, ClientSocket
          sockaddr_in ServerSockAddrIn, ClientSockAddrIn
          WSADATA wsaData
          WORD wVersionRequested
          int retBindVal, retListenVal,  retSendVal, retRecvVal, ClientSockAddrInLen
 ..
 public: void Start_Server()
 ..

--------------------------------------------------------------------------------------------------------------------

FORM1.cp
--------------------------------------------------------------------------------------------------------------------
void Form1::Start_Server(

 ...
 retBindVal = bind(ServerSocket,(sockaddr*) &ServerSockAddrIn, sizeof(ServerSockAddrIn));  //Error Msg #
 ..
 ClientSocket = accept(ServerSocket, (struct sockaddr*) &ClientSockAddrIn, &ClientSockAddrInLen); //Error Msg #
 ..

--------------------------------------------------------------------------------------------------------------------

When I build the application it gives me the following error
Error Msg #1:  errorC2440: 'type cast' : cannot convert from 'sockaddr_in __gc*' to 'sockaddr*
Error Msg #2:  errorC2440: 'type cast' : cannot convert from 'sockaddr_in __gc*' to 'sockaddr*

I guess that I should type cast unmanaged code to managed code. Please kindly guide me to solve this problem. I downloaded VC.NET Samples from microsoft.com. There are Socket samples in it, but they are not clear for me
I am requesting your kind helps
Thank you very much
