Question

Connect()
{
  AfxDaoInit();
  g_Db.Open("",false,false,"odbc;DSN=sy_odbc;UID=sy;PWD=sy")      
  g_rdSet.m_pDatabase=&g_Db;
}
DisConnect()
{
  if(g_Db.IsOpen())
  {
      g_Db.Close();
      g_rdSet.m_pDatabase=NULL;
      return true;
  }
  AfxDaoTerm();
}

Answer 1

这是我客户端程序:
CLSID clsid;
LPCLASSFACTORY  pClf;
LPUNKNOWN pUnk;
IConn *pConn;
HRESULT hr;
if((hr = ::CLSIDFromProgID(L"Server.InfoServe",&clsid))
!= NOERROR) {
   MessageBox("get error",NULL,MB_OK);
   return;
}
if((hr = ::CoGetClassObject(clsid,CLSCTX_INPROC_SERVER
    ,NULL,IID_IClassFactory,(void **)&pClf)) != NOERROR){
    MessageBox("error",NULL,MB_OK);
   return;
}
pClf->CreateInstance(NULL,IID_IUnknown,(void **)&pUnk);
pUnk->QueryInterface(IID_IConn,(void **)&pConn);
pConn->Connect();
....      
pConn->Close();
pClf->Release();
pUnk->Release();
pConn->Release();
我找你说的做了,但不好用,还是非法操作!

Answer 2

pConn->Close();就是pConn->DisConnect();
