A Glass case of Thoughts

Assignment:
Export data in word 2003 format using COM Interop

Problem:
First time export worked just fine. Second time, I received exception “The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)” for “Microsoft.Office.Interop.Word”

Solution:

  
public class CDocumentExporter
{
        static ApplicationClass _word_application;

        public static ApplicationClass AppClass
        {
            get
            {

                if (_word_application == null)
                {
                    _word_application = new ApplicationClass();
                    _word_application.ApplicationEvents2_Event_Quit += new ApplicationEvents2_QuitEventHandler(_word_application_ApplicationEvents2_Event_Quit);
                }
                return _word_application;
            }
        }

        static void _word_application_ApplicationEvents2_Event_Quit()
        {
            _word_application = null;
        }
}//end of class

And just use the CDocumentExporter.AppClass wherever necessary

Important information

You need to add a COM reference to your favorite word object library which should in turn add

• Microsoft.Office.Core
• VBIDE
• Word
   

   

  If you do not see these added, make sure you have PIAs for office version installed on your machine.
