Example


The following example loads a picture in a picture cell from a resource. The user can click a button to save the picture to a buffer and load it into another cell.

C++

BOOL COCXpropertiesDlg::OnInitDialog()

{

m_Spread.SetCol(1);

m_Spread.SetRow(1);

// Create a picture cell type

m_Spread.SetCellType(9);

HINSTANCE h = AfxGetResourceHandle();

// Load the picture

m_Spread.SetTypePictPicture( m_Spread.LoadResPicture((long)h, "IDB_BITMAP1", "BITMAP", 1));

or

CString s;

s.Format(_T("#%d"), MAKEINTRESOURCE(IDB_BITMAP1));

m_Spread.SetTypePictPicture( m_Spread.LoadResPicture((long)h, (LPCTSTR)s, "BITMAP", 1).m_lpDispatch);

}

void COCXpropertiesDlg::OnClickFpbtn1()

{

    CPicture picture;

    VARIANT buffer;

    VARIANT size;

    m_Spread.SetCol(1);

    m_Spread.SetRow(1);

    picture = m_Spread.GetTypePictPicture();

    // Save picture to buffer

    m_Spread.SavePictureBuffer((IDispatch *)picture.m_lpDispatch, 1, &buffer, &size);

    m_Spread.SetCol(2);

    m_Spread.SetRow(1);

    // Create a picture cell type

    m_Spread.SetCellType(9);

    // Load picture from buffer

    m_Spread.SetTypePictPicture(m_Spread.LoadPictureBuffer(&buffer, &size, 1));

    // Use SysFreeString to free the buffer

    SysFreeString(buffer.bstrVal);

}
