InCopy CS6 / Windows: How can I detect if a document is completly loaded?

Hi

In my plugin I have to detect if a document is completely loaded and the layout is open. The user opens the Indesign document in InCopy and I have to know, if the document is opened and all texts are loaded.

I try that with the kAfterOpenDocSignalResponderService, BUT: The InCopy stories are loaded after this responder service! I have to know if the document and all his InCopy articles are loadet.

How can I do that?

I tried it also with kOpenLayoutSignalServiceID. But I don't know exactly how. A sample code?

Thanks

Hans
