How to add a button to a Word document and assign its Click event at run-time
This article demonstrates how you can use a Microsoft Visual Basic for Applications macro to programmatically add a control to a Microsoft Word document and add a Click event handler for that control.
The following steps illustrate how you can create a Word macro that will add a control to a document and assign the Click event of that control at run-time. The steps are for Word. However, you can apply the same concepts to programmatically manipulate controls in Microsoft Excel workbooks.
The ability to manipulate the Visual Basic Project of a Microsoft Office document at run-time requires a reference to the Microsoft Visual Basic for Applications Extensibility library.
Steps to create the sample
Start a new document in Word.
Press Alt+F11 to go to the Visual Basic Editor.
On the Tools menu, click References.
Select the reference for Microsoft Visual Basic for Applications Extensibility.
Insert a new module, and then add the following code example.
Sub Test() 'Add a command button to a new document Dim doc As Word.Document Dim shp As Word.InlineShape Set doc = Documents.Add Set shp = doc.Content.InlineShapes.AddOLEControl(ClassType:="Forms.CommandButton.1") shp.OLEFormat.Object.Caption = "Click Here" 'Add a procedure for the click event of the inlineshape '**Note: The click event resides in the This Document module Dim sCode As String sCode = "Private Sub " & shp.OLEFormat.Object.Name & "_Click()" & vbCrLf & _ " MsgBox ""You Clicked the CommandButton""" & vbCrLf & _ "End Sub" doc.VBProject.VBComponents("ThisDocument").CodeModule.AddFromString sCode End Sub
Run the macro "Test".
Once the macro "Test" finishes running, you will see a new CommandButton control on a new document. When you click the CommandButton control, the Click event of the control fires.
