Hello !
I was trying to "hide" the JavaScript error dialog box, which popups when
the webpage has errors.
Searching, I found the IDocHostUIHandler interface.
But i'm not sure of how to use it. My idea is to change the registry. I have
two functions for do it:
(copied, and modified slightly, from MSDN)
//--------------------------------------------------------------------------
------------------------------

HRESULT SetSomeKeys()
{
    HKEY hKey = NULL;
    HKEY hKey2 = NULL;
    DWORD dwDisposition = NULL;
    LONG lResult = NULL;
    #define CBMAX 256
    size_t cbLength;

    RegCreateKeyEx(HKEY_CURRENT_USER, _T("Software\\MyCompany\\MyApp"),
                   NULL, NULL, REG_OPTION_NON_VOLATILE, KEY_SET_VALUE,
                   NULL, &hKey, &dwDisposition);

    RegCreateKeyEx(hKey, _T("Main"), NULL, NULL, REG_OPTION_NON_VOLATILE,
                   KEY_SET_VALUE, NULL, &hKey2, &dwDisposition);

    RegSetValueEx(hKey2, _T("Error Dlg Displayed On Every Error"), NULL,
REG_SZ,
                  (CONST BYTE*)_T("no"), sizeof(_T("no")));

    RegCloseKey(hKey2);

    RegCloseKey(hKey);

    return S_OK;
}

//--------------------------------------------------------------------------
-------------------------------

HRESULT CBrowserHost::GetOptionKeyPath(LPOLESTR *pchKey, DWORD dwReserved)
{
    HRESULT hr;

    #define CCHMAX 256
    size_t cchLength;

    if (pchKey)
    {
        WCHAR* szMyKey = L"Software\\MyCompany\\MyApp";
        hr = StringCchLengthW(szMyKey, CCHMAX, &cchLength);
        // TODO: Add error handling code here.

        *pchKey = (LPOLESTR)CoTaskMemAlloc((cchLength + 1) * sizeof(WCHAR));
        if (*pchKey)
            hr = StringCchCopyW(*pchKey, cchLength + 1, szKey);
            // TODO: Add error handling code here.

        hr = (*pchKey) ? S_OK : E_OUTOFMEMORY;
    }
    else
        hr = E_INVALIDARG;

    return hr;
}

//--------------------------------------------------------------------------

But I don't know how to use them, can somebody help me?
Thanks !!!

Enrique.
