• Visual Studio Tools for Office Obtaining a local application object from a separate AppDomain

  Hi, I have a scenario using VSTO 2005 SE that requires multiple AppDomains, each of which could manipulate the application's object model using the PIAs. The initial VSTO add-in is obviously passed a local instance of the application object (Microsoft.Office.Interop.Excel.Application). If I pass that instance along to any of the other AppDomains, transparent proxies and remoting gets involved, eventually causing problems when the lease expires (less than 10 minutes). What is the correct way to obtain a local reference to the Excel application object from a separate AppDomain I've tried creating a local instance of the Excel application by reaching into the Running Object Table (ROT), but this only seems to grab the first instance ...Show All

• .NET Development Anyone else believe in Simple client/server apps?

  I am a .net construction worker, but I want to build nice houses, not high rise buildings. I am qualified and enjoy writing practical client/server solutions to problems that are not exceptionally big, of which there are thousands. I do not enjoy, however, and can not seem to bring myself to care about writing applications that are extraordinarily complex and that involve issues like n-tier. I suspect that there are other ways to keep code maintenance and sharing of code easy without all the overhead of presentation, business and data tiers, custom classes that get populated from a database and other similar complicated designs. To me, it takes all the fun out of writing solutions and is not necessary when all your trying to do is to build ...Show All
