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.H

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

public __gc class Form1 : public System::Windows::Forms::Form

{

...

public:

#define PORT 22222

#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.cpp

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

void Form1::Start_Server()

{

....

retBindVal = bind(ServerSocket,(sockaddr*) &ServerSockAddrIn, sizeof(ServerSockAddrIn));  //Error Msg #1

...

ClientSocket = accept(ServerSocket, (struct sockaddr*) &ClientSockAddrIn, &ClientSockAddrInLen); //Error Msg #2

...

}

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



When I build the application it gives me the following errors

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

I'm also interested in fixing this error.  Does anyone know how to convert from 'unsigned short [19]' to 'char' .

There is no meaningful conversion from 'unsigned short [19]' to 'char'.

To be of any help, we need to know what kind of object you have, and why

the compiler thinks it needs to convert it to 'char'.
