I'm still a bit confused about the TCHAR and WCHAR definitions... they seem to convert themselves... i guess these are one of those "C++ Macros" that i've been reading about?

#ifdef _UNICODE
#define TCHAR WCHAR // Unicode is on -> Wide character type
#else
#define TCHAR CHAR // Unicode is off -> Normal character type
#endif

i figured i could just strcat() the strings in the same line, but i'm still trying to figure out C++

i've made the changes stated above, but i am now getting a "Debug Assertion Error" on my line:

From MSDN:

Finally, add a simple OnDocumentComplete event handler.

C++

void STDMETHODCALLTYPE CHelloWorldBHO::OnDocumentComplete(IDispatch *pDisp, VARIANT *pvarURL)
{
    // Retrieve the top-level window from the site.
    HWND hwnd;
    HRESULT hr = m_spWebBrowser->get_HWND((LONG_PTR*)&hwnd);
    if (SUCCEEDED(hr))
    {
        // Output a message box when page is loaded.
        MessageBox(hwnd, L"Hello World!", L"BHO", MB_OK);
    }
}

Notice that the message box uses the top-level window of the site as its parent window, rather than simply passing NULL in that parameter. In Internet Explorer 6, a NULL parent window does not block the application, meaning that the user can continue to interact with the browser while the message box is waiting for user input. In some situations, this can cause the browser to hang or crash. In the rare case that a BHO needs to display a UI, it should always ensure that the dialog box is application modal by specifying a handle to the parent window.
