Run Add-In Functions

To run Add-In functions from the Tasks Pane, you create an attribute in the Tasks Pane «stereotype» Class with the following format:


where Assembly is the name of the Add-In and FunctionName is the name of a public function in the Add-In. Give the attribute an initial value of the text that is to appear in the Tasks Pane. The function receives two parameters and returns a success status, as in the following VB.Net example:


Public Function ShowMyDiagram(ByRef Repository As EA.Repository, ByVal args As Object) As String

          Dim ret As String

          ret = Repository.SQLQuery("select ea_guid from t_diagram where diagram_type='Custom' and StyleEx like

          If ret Is Nothing Then

               ShowMyDiagram = False

               Exit Function

          End If


          Dim oXML As MSXML2.DOMDocument = New MSXML2.DOMDocument



          Dim NodeList As MSXML2.IXMLDOMNodeList = oXML.selectNodes("//ea_guid")

          If NodeList.length = 0 Then

               ShowMyDiagram = False

               Exit Function

          End If


          Dim Node As MSXML2.IXMLDOMNode

          Dim diag As EA.Diagram

          If NodeList.length >= 1 Then

               Node = NodeList.item(0)

               diag = Repository.GetDiagramByGuid(Node.text)



          End If


          ShowMyDiagram = True

End Function
