示例1: RefreshDisplayModeMenu

void CSignalGeneratorDlg::RefreshDisplayModeMenu(void)
{
	// Populate the display mode combo with a list of display modes supported by the installed DeckLink card
	IDeckLinkDisplayModeIterator*	displayModeIterator;
	IDeckLinkDisplayMode*			deckLinkDisplayMode;
	BMDPixelFormat					pixelFormat;
	
	pixelFormat = (BMDPixelFormat)m_pixelFormatCombo.GetItemData(m_pixelFormatCombo.GetCurSel());

	for (int i = 1; i < m_videoFormatCombo.GetCount(); i++)
	{
		deckLinkDisplayMode = (IDeckLinkDisplayMode*)m_videoFormatCombo.GetItemDataPtr(i-1);
		deckLinkDisplayMode->Release();
	}
	m_videoFormatCombo.ResetContent();
	
	if (m_deckLinkOutput->GetDisplayModeIterator(&displayModeIterator) != S_OK)
