Code Invoked under the Application Execution Context

The principal application code constructs that are normally invoked under the application execution context are:

• VBA-initiated ActiveX requests (implemented in ObjectARX).
• ActiveX requests made from external processes, including Visual Basic.
• Modeless dialog boxes posted by ObjectARX applications, or any DLL loaded by AutoCAD.
• All ObjectARX service calls made from the application context, including any ObjectARX-defined callouts that can be triggered from them, including custom object and entity virtual members, AcDb*, AcRx* reactor members, and AcEditorReactor members concerning database objects.
