Hi

I think I missed a very important part of the add-in functionality in i#sharpcode. I have the base add-in which contains the main form. In this main form there is another form for managing addresses. I have then created an add-in for managing campaigns which has it's own win form.

And now my question: How can I call my add-in win form from the base without adding a reference to the add-in (loose coupling)?

Thank you for your help!

Well, the main idea of add-ins is that they are optional / multiple add-ins can be installed - so it doesn't make sense to call a specific addin.

The base add-in can call extensible functionality by building objects from the add-in tree and calling a method on them:

            foreach (ICommand command in AddInTree.BuildItems<ICommand>("/Some/Path", null, false)) {
                command.Run();
            }

AddIns can register "ICommand" objects like this:

    <Path name = "/Some/Path">
        <Class id = "MyID"
               class = "MyAddIn.SomeCommand"/>
    </Path>

You can use any interface, ICommand is just an example.

OK, thank you for your help. I'll try it this way.

Hi  there,

I'm just trying to use the Builditems-Method as described but I still didn't get it to work.

By debugging I could trace the Problem to the "return asm.CreateInstance(instance);"-Line in the CreateInstance-Method of the Runtime-Class.

I get 'null' returned even if the instance-variable is a valid classname. 

The use of the Builditems-Method looks like this: 

ArrayList test = AddInTree.BuildItems("/Controllers/CampaignAdministration", null,true);

The Path looks like this: 

  <Path name="/Controllers/CampaignAdministration">
    <Class id="GoogleAdwords"
           class="Arcos.ERP.Addin.CampaignAdministration.GoogleAdwords"/>
  </Path>

 And the codon:

  public class GoogleAdwords : AbstractCommand
    {
       
        public GoogleAdwords() {
            lala = "mumu"; //The string-property is just here to test if the constructor is called

        }
       
        public string lala { get; set; }

        public override void Run()
        {
            throw new NotImplementedException();
        }
    }

When checking the path in the addintree, the codon is perfectly registered.

Is there something additional i forgot?

 Maybe you're not looking for the class is the right assembly?

ICSharpCode.Core will look for classes in the assemblies referenced in the <Runtime> section of the .addin file.

 Hi Daniel,

Thanks for the quick reply. I wish it was just that...

But there's just 1 assembly, thus it can't be on the wrong place. Furthermore there's also another MenuItem on the same place which works.

EDIT: OK, problem solved, sometimes taking a break is enough to see that Addin and AddIn is not the same thing... :(
