'_ConnectionPtr' : undeclared identifier
我在stdafx.h文件中#import "C:\Program Files\Common Files\System\ado\msado15.dll" no_namespace rename("EOF","rsEOF")
然后在按钮的响应函数中添加代码如下：
void IDS::OnImport()
{
// TODO: Add your control notification handler code here
CString sql;
CoInitialize(NULL);
_ConnectionPtr m_pConnection;
_variant_t RecordsAffected;
try{
HRESULT hr=m_pConnection.CreateInstance("ADODB.Connection");
if(SUCCEEDED(hr))
{
m_pConnection->ConnectionTimeout=3;
m_pConnection->Open("Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=db1;Data Source=JEFFY-A73938B38","","",adModeUnknown);
AfxMessageBox("数据库连接成功!");
//return true;
}
}
catch(_com_error e)
{
CString temp;
temp.Format("数据库连接出错：%s",e.ErrorMessage());
AfxMessageBox(temp);
//return false;
}
int num=m_list.GetItemCount();
for(int i=0;i<num;i++)
{
CString time=m_list.GetItemText(i,0);
CString info=m_list.GetItemText(i,1);
CString proto=m_list.GetItemText(i,2);
CString sip=m_list.GetItemText(i,3);
CString sport=m_list.GetItemText(i,4);
CString dip=m_list.GetItemText(i,5);
CString dport=m_list.GetItemText(i,6);
sql = "Insert into data values('"+time+"','"+info+"','"+proto+"','"+sip+"','"+sport+"','"+dip+"','"+dport+"')";
try
{
m_pConnection->Execute((_bstr_t)sql,&RecordsAffected,adCmdText);
}
catch(_com_error e)
{
CString temp;
temp.Format("出错：%s",e.ErrorMessage());
AfxMessageBox(temp);
}
}
}
出现的错误是：

怎么解决啊？
[解决办法]
首先
rebuild all
[解决办法]
C:\Program Files\Common Files\System\ado\msado15.dll
//确定此文件在此目录下？
