Documents.DocumentCreated Event (Visio)
Published: July 16, 2012
Occurs after a document is created.
The DocumentCreated event is often added to the EventList collection of a Microsoft Visio template file (.vst). The event's action is triggered whenever a new document is created based on that template.
If you are using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.
If you want to create your own Event objects, use the Add or AddAdvise method. To create an Event object that runs an add-on, use the Add method as it applies to the EventList collection. To create an Event object that receives notification, use the AddAdvise method. To find an event code for the event you want to create, see Event codes.
You can add DocumentCreated events to the EventList collection of an Application object, Documents collection, or Document object. The first two are straightforward; if a document is opened or created in the scope of the Application object or its Documents collection, the DocumentCreated event occurs.
However, adding a DocumentCreated event to the EventList collection of a Document object makes sense only if the event's action is visActCodeRunAddon. In this case, the event is persistable; it can be stored with the document. If the document that contains the persistent event is opened, its action is triggered. If a new document is based on or copied from the document that contains the persistent event, the DocumentCreated event is copied to the new document and its action is triggered. However, if the event's action is visActCodeAdvise, that event is not persistable and therefore is not stored with the document; hence, it is never triggered.
You can prevent code from running in response to the DocumentCreated, DocumentOpened, or DocumentAdded event and all events from firing by setting the value of the EventsEnabled property of an Application object to False.
This VBA example shows how to count shapes added to a drawing that are based on a master called Square.
The DocumentCreated event handler runs when a new drawing based on the template that contains this code is created. The handler initializes an integer variable, intNumberOfSquares, which is used to store the count.
The ShapeAdded event handler runs each time a shape is added to the drawing page, whether the shape is dragged from a stencil, drawn with a drawing tool, or pasted from the Clipboard. The handler checks the Master property of the new shape and, if the shape is based on the Square master, increments intNumberOfSquares.
Dim intNumberOfSquares As Integer Private Sub Document_DocumentCreated(ByVal vsoDocument As Visio.IVDocument) 'Initialize number of squares added. intNumberOfSquares = 0 End Sub Private Sub Document_ShapeAdded(ByVal vsoShape As Visio.IVShape) Dim vsoMaster As Visio.Master 'Get the Master property of the shape. 'the shape was created locally. Set vsoMaster = vsoShape.Master 'Check whether the shape has a master. If not, If Not (vsoMaster Is Nothing) Then 'Check whether the master is "Square". If vsoMaster.Name = "Square" Then 'Increment the count for the number of squares added. intNumberOfSquares = intNumberOfSquares + 1 End If End If MsgBox "Number of squares: " & intNumberOfSquares, vbInformation, _ "Document Created Example" End Sub
