Examples

The following example demonstrates a Ribbon framework image factory method that loads an image from the Ribbon resource file.

The m_pifbFactory member variable is a pointer to an IUIImageFromBitmap object.

// Factory method to create IUIImages from resource identifiers.
HRESULT CShapeHandler::CreateUIImageFromBitmapResource(
                         LPCTSTR pszResource, __out IUIImage **ppimg)
{
    HRESULT hr = E_FAIL;

    *ppimg = NULL;

    if (NULL == m_pifbFactory)
    {
        hr = CoCreateInstance(
               CLSID_UIRibbonImageFromBitmapFactory, 
               NULL, 
               CLSCTX_ALL, 
               IID_PPV_ARGS(&m_pifbFactory));
        if (FAILED(hr))
        {
            return hr;
        }
    }

    // Load the bitmap from the resource file.
    HBITMAP hbm = NULL;
    hbm = (HBITMAP) LoadImage(
                      GetModuleHandle(NULL), 
                      pszResource, 
                      IMAGE_BITMAP, 
                      0, 
                      0, 
                      LR_CREATEDIBSECTION);

    if (NULL == hbm)
    {
      return HRESULT_FROM_WIN32(GetLastError());
    }

    // Use the factory implemented by the framework to produce an IUIImage.
    hr = m_pifbFactory->CreateImage(hbm, UI_OWNERSHIP_TRANSFER, ppimg);
    if (FAILED(hr))
    {
      DeleteObject(hbm);
    }
    return hr;
}
