How do you create multiple execution windows for a custom opterator interface

Question

I am starting to create a custom operator interface for TestStand 3.5 using Labview 8.0.  This is my first exposure to custom operator interfaces (and ActiveX).  The example operator interfaces have only one execution window that changes based on the executions combo box.  My sequence is going to be run with the parallel sequence model (2 test sockets).  So I want my custom operator interface to have 2 execution windows, one for each test socket.  How can I do this?  I created a second execution window but it just mirrors the first execution window.

Hi, All:
 With the similar approach, I create a multiple window user interface with CVI. Although it can run, the Execution view doesn't display
anything while execution. In my user interface, there is an applicaiton manager resident in Parent form, and every child forms has
itsown Exection view and Manager.
 Referred to the C# sample, in the function rivate void DisplayExecution(Execution execution)
   if (executionForm == null) // execution is not in a form, make a new form
    executionForm = new ExecutionForm(this, this.axApplicationMgr, execution);
    this.mChildFormsKeyedByViewMgr.Add(executionForm.GetViewMgr().GetOcx(), executionForm);
    SetNewChildFormLocation(executionForm);
 I guess the execution form "hook" the exectuion view manager via Add(), so the exectuion view can be updated properly.
And according to reference manual of teststand, it mentions that "The application sets the ExecutionViewMgr.UserData property to
attach a handle, reference, or pointer that represents the window." But when I try to utilize this method, I got 2 problems:
1. How to get a window handle of a CVI panel? As execution view are resident in child panels, so I may need the window handle of
 individual child panels.
2. Even the window hanlde is gotten, how can I convert it to a VARIANT Type? According to the function panle of
TSUI_ExecutionViewMgrSetUserData (, NULL, ), the last parameter is a "VARIANT".
Any comments or instructions for my assumption?
Thank you for your help.
