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 equivalent 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);
}
