Is it possible to call OfficeCodeBehind methods externally? I have created a Word 2003 template using VSTO 2003, and I would like to call a few of the methods implemented in the OfficeCodeBehind class from a Windows Forms application. I know that I can link the methods to CommandBar buttons and execute them by calling the CommandBarButton.Execute method. What I'm hoping to do is call them using a syntax similar to the Application.Run syntax that is used to execute VBA macros. Here's how I'm calling a method implemented in the OfficeCodeBehind class from my Windows Forms application now: object objTemplatePath = "c:\\program files\\microsoft office\\templates\\FirstVSTOtemplate.dot"; object oMissing = System.Reflection.Missing.Value; Microsoft.Office.Interop.Word.ApplicationClass objApp = new Microsoft.Office.Interop.Word.ApplicationClass(); Microsoft.Office.Interop.Word.Document objDoc = objApp.Documents.Add(ref objTemplatePath, ref oMissing, ref oMissing, ref oMissing); Office.CommandBarControl cbc = objDoc.CommandBars["Menu Bar"].Controls["Custom Code"]; Office.CommandBarButton cbb = (Office.CommandBarButton)((Office.CommandBarPopup)cbc).Controls["Populate Scalars"]; cbb.Execute(); I created a method called PopulateScalars() in OfficeCodeBehind that is hooked to the Click event of the 'Populate Scalars' menu item. The code above executes the method, but I have no way to determine when the method has finished, or what the return value is. What I would like to do ideally is call the PopulateScalars method directly from my Windows Forms application. Any help will be greatly appreciated. Thanks, Darryl R.
