c++builder编写一个聊天程序，运用sendto函数时出现了错误。请大神指教~~
报错：
[C++ Error] Unit1.cpp(46): E2034 Cannot convert 'TWinsock *' to 'unsigned int'
[C++ Error] Unit1.cpp(46): E2342 Type mismatch in parameter 's' (wanted 'unsigned int', got 'TWinsock *')
部分代码如下：
  sockaddr_in * RemoteSockAddr;
  char*IDBuffer;
  Edit_IDAddr->GetSelTextBuf(IDBuffer,100);

  RemoteSockAddr->sin_family=AF_INET;
  RemoteSockAddr->sin_port=6000;
  RemoteSockAddr->sin_addr.S_un.S_addr =inet_addr(IDBuffer);

  char*SendBuffer;
  Edit_Send->GetSelTextBuf(SendBuffer,100);
  sendto(Winsock1,SendBuffer,Edit_IDAddr->GetTextLen()+1 ,0,
  (sockaddr*)RemoteSockAddr,sizeof(sockaddr_in));

[解决办法]
Cannot convert 'TWinsock *' to 'unsigned int'
提示的多清楚啊，你查查sendto函数的用法，就明白了

[解决办法]
参数类型不正确
