Run Add-In Functions
Another facility that you can provide to support users of your technology is to run Add-In functions from a Learning Center page. You define each function using an attribute in the Learning Center Stereotype element, the attribute having the format:
"Assembly::FunctionName()"
Assembly is the name of the Add-In and FunctionName is the name of the public function to run, within the Add-In. Type the text that is to appear in the Learning Center page into the Initial Value field of the attribute.
Example
This function is written under VB.Net:
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
'*;MDGDgm=MyDiagrams::MyCustomDiagram;*'")
If ret Is Nothing Then
ShowMyDiagram = False
Exit Function
End If
Dim oXML As MSXML2.DOMDocument = New MSXML2.DOMDocument
oXML.loadXML(ret)
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)
Repository.OpenDiagram(diag.DiagramID)
Repository.ShowInProjectView(diag)
End If
ShowMyDiagram = True
End Function
