Canceling a Network Connection

To cancel a connection to a network resource, an application can call the WNetCancelConnection2 function, as shown in the following example.

DWORD dwResult;

dwResult = WNetCancelConnection2("z:",

CONNECT_UPDATE_PROFILE, // remove connection from profile

FALSE); //fail if open files or jobs

if (dwResult == ERROR_NOT_CONNECTED)

{

TextOut(hdc, 10, 10, "Drive z: not connected.", 23);

return FALSE;

}

else if(dwResult != NO_ERROR)

{

// An application-defined error handler is demonstrated in the

// section titled "Retrieving Network Errors."

NetErrorHandler(hwnd, dwResult, (LPSTR)"WNetCancelConnection2");

return FALSE;

}

TextOut(hdc, 10, 10, "Connection closed for z:.", 25);

The WNetCancelConnection function is supported for compatibility with earlier versions of Windows for Workgroups. For new applications, use WNetCancelConnection2.
