arcobjects - Override default ArcMap editing error dialog

Is there a way to override this dialog easily?

The custom message is already there, but I'm guessing that my client will be more annoying and will want a translated message.

Can I replace that dialog? This dialog is the one that appear if you thrown an exception from inside a class extension.

Since this has gone unanswered and it looks like a similar issue I had when aborting a delete feature operation, I'll offer my workaround (which I based on something I found on the old Esri forums). It's hacky and you may already be doing this and were looking for a less-hacky method.

Add FindWindow and EndDialog to a class (you might already have a PInvoke class):

public class PInvoke
{
    [DllImport("user32.dll")]
    public static extern IntPtr FindWindow(String lpszClass, String lpszWindow);


    [DllImport("user32.dll")]
    public static extern int EndDialog(IntPtr hDlg, IntPtr nResult);
 }

Add a timer to your extension class:

private Timer timerDeleteEsriDeleteMessage;

And a property for the timer:

    private Timer TimerRemoveEsriDeleteMessage
    {

        get
        {
            if (timerDeleteEsriDeleteMessage == null)
            {
                timerDeleteEsriDeleteMessage = new Timer();
                timerDeleteEsriDeleteMessage.Interval = 1;
                timerDeleteEsriDeleteMessage.Tick += new EventHandler(OnTimerDeleteEsriDeleteMessageTick);
            }

            return timerDeleteEsriDeleteMessage;

        }
    }

Add the method that actually shuts down the window:

    private void OnTimerDeleteEsriDeleteMessageTick(object timerObject, EventArgs myEventArgs)
    {
        if (((Timer)timerObject).Tag.ToString().Equals("AbortOperation"))
        {
            // Close the dialog with the caption 'Delete'
            IntPtr textBoxHandle = PInvoke.FindWindow(null, "Delete");

            PInvoke.EndDialog(textBoxHandle, (IntPtr)DialogResult.OK);
        }

        this.TimerRemoveEsriDeleteMessage.Stop();
    }

Now the timer can be started just before a delete operation.

            // I show my dialog here (if I want one)

            // then start the timer, then abort the operation

            this.TimerRemoveEsriDeleteMessage.Start();
            this.TimerRemoveEsriDeleteMessage.Tag = "AbortOperation";
            ArcMap.Editor.AbortOperation();

I'm thinking this approach may work for the Create Feature Task could not be completed. message (maybe by replacing Delete with Create in the OnTimerDeleteEsriDeleteMessageTick method).
