Type: System.String

The name of the DDE/OLE link, as returned from the LinkSources method.

The name of the procedure to be run when the link is updated. This can be either a Microsoft Office Excel 4.0 macro or a Visual Basic procedure. Set this argument to an empty string ("") to indicate that no procedure should run when the link is updated.

The following code example gets the collection of all DDE links in the current workbook and then uses the SetLinkOnData method to run a macro named UPDATE_MACRO whenever one of the links is updated.

This example is for a document-level customization.

private void WorkbookSetLinkOnData()
    Array links = (Array)this.LinkSources(Excel.XlLink.xlOLELinks);

    if (links != null)
        for (int i = 1; i <= links.Length; i++)
            this.SetLinkOnData((string)links.GetValue(i), "UPDATE_MACR0");
        MessageBox.Show("The workbook contains no DDE/OLE links.");
