Do you want to have a feature (in your own application) of "Clear <br>

History" like IE5 does in its "Internet Options"? <br>

  <br>

Here is how you can do it. It's not documented, but I have tested it and <br>

 it works, with VC++ 6.0 and Win98/NT. <br>

  <br>

  <br>

#include <UrlHist.h> <br>

// Delete all items in History folder <br>

HRESULT ClearHistory() <br>

{ <br>

    IUrlHistoryStg2* pUrlHistoryStg2 = NULL; <br>

    HRESULT hr = CoCreateInstance(CLSID_CUrlHistory, <br>

        NULL, CLSCTX_INPROC, IID_IUrlHistoryStg2, <br>

        (void**)&pUrlHistoryStg2); <br>

    if (SUCCEEDED(hr)) <br>

    { <br>

        hr = pUrlHistoryStg2->ClearHistory(); <br>

        pUrlHistoryStg2->Release(); <br>

    } <br>

    return hr; <br>



} <br>

  <br>

  <br>

  <br>
