本文实例讲述了VC基于ADO技术访问数据库的方法。分享给大家供大家参考。具体如下：
一、在StdAfx.h文件中添加
二、数据库应用层操作
void CADOExample1Dlg::OnBtnQuery()
{
// TODO: Add your control notification handler code here
CoInitialize(NULL);
_ConnectionPtr pConn(__uuidof(Connection));
_RecordsetPtr pRst(__uuidof(Recordset));
pConn->ConnectionString = "Provider=SQLOLEDB.1;Password=123456;Persist Security Info=True;User ID=sa;Initial Catalog=db_test;Data Source=.";
pConn->Open("","","",adConnectUnspecified);
pRst = pConn->Execute("select * from tb_image",NULL,adCmdText);
while(!pRst->rsEOF)
{
((CListBox*)GetDlgItem(IDC_LIST1))->AddString(
(_bstr_t)pRst->GetCollect("imageID"));
pRst->MoveNext();
}
pRst->Close();
pConn->Close();
pRst.Release();
pConn.Release();
CoUninitialize();
}
希望本文所述对大家的VC程序设计有所帮助。
