最簡單調用系統的“數據鏈接屬性”窗口實例

#import "c:/program files/common files/system/Ole DB/oledb32.dll" rename_namespace("oledb")
#import "c:/program files/common files/system/ado/msado15.dll" no_namespace rename ("EOF", "adoEOF")
#include <iostream>
using namespace std;
int main()
{
 ::CoInitialize(NULL);
 oledb::IDataSourceLocatorPtr    p_IDSL = NULL;
 _ConnectionPtr                  p_conn = NULL;
 p_IDSL.CreateInstance( __uuidof( oledb::DataLinks ));
 p_conn = p_IDSL->PromptNew();
 int i = p_conn->GetState();
 cout<<i<<endl;
 ::CoUninitialize();
 return 0;
