Examples

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 Sub WorkbookSetLinkOnData()
    Dim Links As Array = _
        CType(Me.LinkSources(Excel.XlLink.xlOLELinks),  _
        Array)
    If Links IsNot Nothing Then
        Dim i As Integer
        For i = 1 To Links.Length
            Me.SetLinkOnData(Links(i), "UPDATE_MACR0")
        Next i
    Else
        MsgBox("The workbook contains no DDE/OLE links.")
    End If
End Sub

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");
        }
    }
    else
    {
        MessageBox.Show("The workbook contains no DDE/OLE links.");
    }
}
