 > can you clarify what object type is ComParent in the code ?

Actually I've yet to use it but AFAIK, the ComParent object type is just that - an object of type "object" .

eg. In this example objApp is the ComParent.

 private void btnGetDatabasePath_Click(object sender, EventArgs e)
{
 object objApp;
 object objDatabasePath;
 object objStocks;
 try
 {
 // Get the class type
 Type objClassType; objClassType =      Type.GetTypeFromProgID("Broker.Application");
 // Instantiate AmiBroker
 objApp = Activator.CreateInstance(objClassType);
 // Get the database path
 // Remember to add a "using" at the top for "System.Reflection" or else use "System.Reflection.BindingFlags" below.
 objDatabasePath = objApp.GetType().InvokeMember("DatabasePath", BindingFlags.GetProperty, null, objApp, null);
 // Set the window text box to the database path.
 // As the database path is an object we must convert it to a string.
 txtDatabasePath.Text = Convert.ToString(objDatabasePath);
 // get stocks object
 objStocks = objApp.GetType().InvokeMember("Stocks",  BindingFlags.GetProperty, null, objApp, null);
 stocksTextBox.Text = Convert.ToString(objStocks);
}
