UCOMIRunningObjectTable.GetObject

wstueve · December 18th, 2003, 11:47 AM

I have been trying to write a utility which will walk through the running objects table and return the object based on the class name and window handle. I have most of the code so far, but now I am stuck. Whenever I walk through the ROT, my code only grabs the first instance opened of the application. It does output x times where x is the number of acad apps opened. I wish for it to iterate through each instance of AutoCAD and output something to each one. Any MS gurus out there that can tell me how to do this? I am pretty new to ROT and monikers, so if you can just point me to the right objects/methods, I would be forever grateful!

Thanks,
Wes

Code:

using System;
using System.Runtime.InteropServices;
using AutoCAD;

namespace Hei.Utility.COMConnectors {

public class ROTWalker {
        [DllImport ("Ole32.Dll")]
        public static extern int CreateBindCtx ( int reserved, out UCOMIBindCtx
            bindCtx );

        public ROTWalker() {
            UCOMIBindCtx bc;
            ROTWalker.CreateBindCtx ( 0, out bc );
            UCOMIRunningObjectTable rot;
            bc.GetRunningObjectTable ( out rot );

            UCOMIEnumMoniker enumMkr;
            rot.EnumRunning ( out enumMkr );
            UCOMIMoniker[] elts = new UCOMIMoniker[1];
            int cnt;
            int ret;
            Object o = new object();
            AcadApplication acadApp;
            while ( ( ret = enumMkr.Next ( 1, elts, out cnt ) ) >= 0 && ( cnt > 0 ) ) {
                string displayName;
                elts[0].GetDisplayName ( bc, null, out displayName );
                Console.WriteLine(displayName);
                rot.GetObject(elts[0], out o);
                if (displayName == "!{1365A45F-0C8F-4806-A26A-6B22AD37EC66}") {
                    acadApp = ((AcadApplication) o);
                    acadApp.ActiveDocument.Utility.Prompt("hehehehe\n\n");
                }
            }
        }
    }
}
