Examples
The following code example demonstrates how to create a smart tag and an action in an Excel add-in project. To use this example, run the code from the ThisAddIn class.
WithEvents displayAddress As Microsoft.Office.Tools.Excel.Action
Private Sub AddSmartTag()
    Dim smartTagDemo As Microsoft.Office.Tools.Excel.SmartTag = _
        Globals.Factory.CreateSmartTag(
        "www.microsoft.com/Demo#DemoSmartTag",
        "Demonstration Smart Tag")
    ' Specify a term and an expression to recognize.
    smartTagDemo.Terms.Add("sale")
    smartTagDemo.Expressions.Add( _
        New System.Text.RegularExpressions.Regex( _
        "[I|i]ssue\s\d{5,6}"))
    displayAddress = Globals.Factory.CreateAction("To be replaced")
    ' Add the action to the smart tag.
    smartTagDemo.Actions = New Microsoft.Office.Tools.Excel.Action() { _
            displayAddress}
    ' Add the smart tag. 
    Me.VstoSmartTags.Add(smartTagDemo)
End Sub
private Microsoft.Office.Tools.Excel.Action displayAddress;
private void AddSmartTag()
{
    Microsoft.Office.Tools.Excel.SmartTag smartTagDemo =
        Globals.Factory.CreateSmartTag(
            "www.microsoft.com/Demo#DemoSmartTag",
            "Demonstration Smart Tag");
    // Specify a term and an expression to recognize.
    smartTagDemo.Terms.Add("sale");
    smartTagDemo.Expressions.Add(
        new System.Text.RegularExpressions.Regex(
        @"[I|i]ssue\s\d{5,6}"));
    displayAddress = Globals.Factory.CreateAction("To be replaced");
    // Add the action to the smart tag.
    smartTagDemo.Actions = new Microsoft.Office.Tools.Excel.Action[] { 
        displayAddress };
    // Add the smart tag. 
    this.VstoSmartTags.Add(smartTagDemo);
    displayAddress.BeforeCaptionShow += new 
        Microsoft.Office.Tools.Excel.BeforeCaptionShowEventHandler(
        DisplayAddress_BeforeCaptionShow);
    displayAddress.Click += new 
        Microsoft.Office.Tools.Excel.ActionClickEventHandler(
        DisplayAddress_Click);
