如何编程清除IE的历史记录

我们只要调用如下ClearHistory函数就可以删除IE的历史记录

#include <wininet.h>
#include <UrlHist.h>
#include <SHLGUID.H>
#include <OBJBASE.H>

HRESULT ClearHistory()
{
HRESULT hr;
CoInitialize(NULL);
{
      IUrlHistoryStg2* pUrlHistoryStg2 = NULL;
      hr= CoCreateInstance(CLSID_CUrlHistory,NULL,1, IID_IUrlHistoryStg2,(void**)&pUrlHistoryStg2);
      if (SUCCEEDED(hr))
      {        
         hr = pUrlHistoryStg2->ClearHistory();
         pUrlHistoryStg2->Release();
       }
}
CoUninitialize();
return hr;
}
