Examples

When you use accelerator keys, such as TAB, you might want to override the default host behavior. This example shows how to disable the default tabbing behavior of the host. The code returns S_OK to indicate that the message was handled.

CYourControlSite::TranslateAccelerator(MSG *pMsg, DWORD dwFlags)
{
    HRESULT hr = S_FALSE;
    
    if (pMsg && pMsg->message == WM_KEYDOWN && pMsg->wParam == VK_TAB) {
        // The message was handled.
        hr = S_OK;
    }
    return hr;
}
