Just emphasising that this requires a copy of Access on the machine where you will run the code.

That KB article works says macros but it's actually running an Access module, ie VBScript.  It doesn't seem to work for Access macros.  The error I get whenever I try to call a macro with this code is:

An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll

BTW, I'm using Access 2003 and .net 1.1.  Is there any reason I need to be at .net 2.0?

 

by: adwisemanPosted on 2007-07-23 at 09:49:15ID: 19549102

I found the solution.  Here's the code I used:

                        Access.ApplicationClass oAccess = new Access.ApplicationClass();
                  oAccess.Visible = true;
                  oAccess.OpenCurrentDatabase("c:\\db1.mdb", false, "");

                  // Run the macro
                  oAccess.DoCmd.RunMacro(("myMacro" as Object), (1 as Object),
                        (true as Object));

                  Console.WriteLine("Macro Complete");

                  // Quit Access and clean up.
                  oAccess.DoCmd.Quit(Access.AcQuitOption.acQuitSaveNone);
                  System.Runtime.InteropServices.Marshal.ReleaseComObject (oAccess);
                  oAccess = null;
