retrive currentDiagram

[defi]

Hi!
I'm tying to do an add-in in C#. To begin with the code i have to retrieve the currentDiagram that i have on Enterprise Architect. I use the following code:

maindiagram = repository.GetCurrentDiagram();
where maindiagram is defined like an EA.Diagram.

When i debug the whole program it gets me the warning that maindiagram  is always = 0, how is that possible?
Can someone please help me?

Thank you.

do you mean == null ?
if thats the case you dont have a diagram opened.
repository.GetCurrentDiagram()
always shows the currently opened and shown diagram

Yes sorry, == null.
But i open the diagram that i made and then start the add-in with the diagram open and nothing, it result ==null.
I don't get it why.

never stepped over this.
for me getCurrentDiagram() works quite well.
Perhaps it could be useful if you provide us some code of yours.

Here is the code where i make the connection with the diagram in enterprise architect.

public MDGBuilder(EA.Repository repository)
        {
            Console.WriteLine("Hello");
            
            MDG graph = new MDG();
            //collegamento con il diagramma in Enterprise Architect
            EA.Diagram maindiagram; //diagramma corrente
            this.modelRepository = repository; //repository del diagramma
            maindiagram = repository.GetCurrentDiagram(); //recupero del diagramma
            if (maindiagram != null)
            {
                this.diagramId = maindiagram.DiagramID; //identificativo del diagramma
            }
            buildMDG(graph);
            calculateCycle();
            
            
        }

i hope it helps you to discover the problem. Thank you.

Hi,
I guess your code is called as reaction to the EA_Connect() AddIn event, right?
This event occurs on startup of EA, so if you open a diagram this will occur after(!) this event was issued, in this state getCurrentDiagram() will never see a currently opened diagram.
This might also be the reason for the issues you have mentioned in your other thread posted here.
I think you wil be better off to initiate your AddIn specific actions as reaction on either the EA_OnPostOpenDiagram() event or even better to an AddIn specific menu command selection.

BTW, you might find Geert Bellekens AddIn framework helpful to use as base for C# EA AddIn development: https://github.com/GeertBellekens/Enterprise-Architect-Add-in-Framework
He also posted some useful articles about this in the community site, e.g. http://community.sparxsystems.com/tutorials/tool-integration/create-your-first-c-enterprise-architect-add-10-minutes

Best regards and HTH,

My EA_Connect() is the following

Code: [Select]

public string EA_Connect(Repository repository)
        {
            return "";
        }


is better if I remove it and put the other one that you adviced me to?


Thank you a lot for your help, and the links that you send me will be very helpful to me.
Thank you a lot!
