Connect to second dxdesigner?

If you do set one to the get obect and open the second one yourself, it should work.

app1 = getobject(...)

app2 = createobject(...)

Hi,

I stumbled over the same issue and opened two SRs in 2010, 2332128450 for DxD and 2332128540 for EXP (stucked at getObject(), not aware of 'FindApplication').

Both were closed without solution.

Now I've learned at least how to do it for EXP, thanks.

Best Regards

Since I develop in C#, I came up with the following solution:

internal static class RunningObjectTable
{
    // call into ole22.dll to retrieve the GetRunningObjectTable function
    [DllImport("ole32.dll")]
    private static extern int GetRunningObjectTable(int reserved, 
        out IRunningObjectTable prot);
 
    // call into ole32.dll to retrieve the CreateBindCtx function
    [DllImport("ole32.dll")]
    private static extern int CreateBindCtx(int reserved, 
        out IBindCtx ppbc);
 
    /// <summary>
    /// Returns a list of instance objects from the running objects table (ROT)
    /// that match the specified application name (<paramref name="appName"/>).
    /// </summary>
    /// <param name="appName">Name of the application to find instances for.</param>
    /// <returns>A list of instances of the specified application.</returns>
    public static IEnumerable<T> GetInstancesWithName<T>(string appName)
    {
        IRunningObjectTable runningObjTable;
        IEnumMoniker monikerEnum;
 
        IMoniker[] monikers = new IMoniker[1];
        List<T> instances = new List<T>();
 
        GetRunningObjectTable(0, out runningObjTable);
        runningObjTable.EnumRunning(out monikerEnum);
        monikerEnum.Reset();
 
        // loop through the ROT looking for appName
        while (monikerEnum.Next(1, monikers, IntPtr.Zero) == 0)
        {
            IBindCtx ctx;
            CreateBindCtx(0, out ctx);
 
            string runningObjName = string.Empty;
            monikers[0].GetDisplayName(ctx, null, out runningObjName);
 
            // when found, add the instance object to the List
            if (runningObjName.Contains(appName))
            {
                object runningObjValue;
                runningObjTable.GetObject(monikers[0], out runningObjValue);
                instances.Add((T)runningObjValue);
            }
        }
 
        return instances;
    }
}

This class finds all instances of DxDesigner (or any other application, for that matter) in the Running Object Table (ROT) and casts them to type T. It allows for the following:

var instances = RunningObjectTable.GetInstancesWithName<ViewDraw.Application>("Viewdraw.Application");
foreach (var instance in instances)
{
    string instancePathProject = instance.GetProjectData().GetProjectFilePath();
    if (instancePathProject == _pathProject)
    {
        this.Application = instance;
        break;
    }
}

Or, you could pop up a dialog asking the user which instance they'd like to "connect" to, as I do for Expedition.
