在服务器端运行VBA功能从WCF服务访问数据库

Question

I've been researching for days and I've gotten to the point where my WCF service creates an Access object via com/interop. I've ran the OpenCurrentDatabase call for the Access object without an error but Application.CurrentDB is still nothing/null. If the CurrentDB is nothing then I surely can't call Application.Run "myFunction" I realize WCF services aren't meant to be user interactive, but it's a long story why I'm trying to go this route. Basically I need to have a proof of concept ready sooner rather than later and the alternative (correct) route involves the complete re-writing of a large complex access VBA application. It's not a permissions issue, I have the IIS user names added to the security tab. What I really need is a way to set Environment.UserInteractive to true so my WCF service can create an instance of Access on my server machine, run the VBA functions, close out, return true. I'm using VS 2010 for the WCF, IIS 7 for my server, Access 2010 for the VBA application. Please help!

The answer is to have the WCF service write the access macro name to a database and have a desktop application on the server machine monitor the database. The desktop application loads access, performs the actions, and writes back to the database upon completion. The WCF service monitors the database waiting for an "operation complete" status and returns the result.
