problems in VSTA integration   

our application is integrated with VBA. and VBA runs correctly.

I am trying to integrate VSTA to our VBA enabled application. 

I did most of tasks in VSTA integration manual and basic features runs.

but when trying to invoke some method ( call our object model method) in 
proxy, error occurs.

========== error msg ==========

System.Reflection.TargetException, mscorlib

System.Reflection.TargetException: Error in the application.

============================================

test code is :

        doc = Application.ActiveDocument
        entity = doc.CreateEntity("CRDBody", "Body1")
        entity.Test("Test") // error occurs here

entity is a our object model (CRDBody) which implements IDispatch.

it derive IDispatchImpl and implement Invoke and GetIDsOfNames because of 
some complicate reason.

test code runs correctly in VBA. 

I can't find exact reason of the error because I can't see Proxy code 
(ComTypeAdapter).



and I tried other way in DOWNLOAD board. ( sample that use 
CreateExcelInstance()  ).

in that case ( use our object model without proxy ) , no problem. but in 
that case, we have to

modify all proxy code manually. in current situaion it is not good method 
for us.

I hope you can give me some advise about above error.



and some questions.

1. when will official version of VSTA be released? or can you tell me VSTA 
release schedule?

2. Can I generate proxy code that access object model directly ( like sample 
that use CreateExcelInstance()  )?

    It is very difficult for me to modify all proxy code because we have so 
many object models.



Any help is greatly appreciated.  sorry for my bad english >_<
