This example is for a document-level customization.

private void WorkbookLinkInfo()
{
    // Get the collection of DDE/OLE links in the workbook.
    Array links = (Array)this.LinkSources(Excel.XlLink.xlOLELinks);

    // If there are DDE/OLE links, then display how each link
    // updates.
    if (links != null)
    {
        for (int i = 1; i <= links.Length; i++)
        {
            string linkName = (string)links.GetValue(i);
            int updateValue = (int)this.LinkInfo(linkName,
                Excel.XlLinkInfo.xlUpdateState,
                Excel.XlLinkInfoType.xlLinkInfoOLELinks);

            if (updateValue == 1)
            {
                MessageBox.Show(linkName + " link updates automatically.");
            }
            else if (updateValue == 2)
