在win2000中如何通过编程实现禁用或者启动本地连接

Question

winxp+sdk+vc6
这个函数调用了"连接"的属性对话框,用的上下文菜单那条路.
试试替换一下这句:cmi.lpVerb =MAKEINTRESOURCE(8) ;//"Properties";
8是模拟点击"属性(R)",不知道"禁止(B)"是多少.
hwnd传this就成.在2000下使用需要做点修改,而且我本来是用的无线网卡.
方法不好,投机取巧,不过能用.int ShowConfigDlg(HWND hwnd)
{
LPITEMIDLIST pidlControlPanel;

Answer 1

还有更好的方法吗？先谢谢“anywn_cwh(我有个问题) ”

Answer 2

InternetSetOption
具体请查阅MSDN

Answer 3

void SetGlobalOffline(BOOL fGoOffline)
   {
      INTERNET_CONNECTED_INFO ci;      memset(&ci, 0, sizeof(ci));
      if(fGoOffline) 
      {
         ci.dwConnectedState = INTERNET_STATE_DISCONNECTED_BY_USER;
         ci.dwFlags = ISO_FORCE_DISCONNECTED;
      } 
      else 
     {
        ci.dwConnectedState = INTERNET_STATE_CONNECTED;
     }     InternetSetOption(NULL, 
         INTERNET_OPTION_CONNECTED_STATE, &ci, sizeof(ci));
   }
