You can call EAServer components from within a PowerDynamo script by using:
The PowerDynamo SQL tag (must return a result set)
The PowerDynamo COMPONENT tag (may return a result set)
The connection.CreateQuery method (must return a result set)
The connection.CreateComponent method (must return a result set)
The java.CreateComponent method (no restriction on the return)
An ActiveX object through the PowerDynamo CreateObject method (no restriction on the return)
The SQL tag, COMPONENT tag, and the connection.CreateQuery and connection.CreateComponent methods allow PowerDynamo to call EAServer components as though they were MASP. Each MASP invocation creates an instance of the component, invokes the method and then destroys the component instance. You can also use the COMPONENT tag to access ActiveX and Java objects—however, just as with MASP, each invocation creates an instance of the component, invokes the method, and then destroys the component instance. The PowerDynamo CreateObject method allows you to create an instance of an ActiveX object and access its methods and properties from within a script. The ActiveX object exists until it goes out of scope or until the ActiveX variable is assigned a new value. The PowerDynamo java.CreateComponent method allows you to create an instance of a Java object and access its methods and properties from within a script. The Java object exists until it goes out of scope.
