Creates an instance of TCustomConnection
Provides the interface for a method that processes message records. 
Destroys the instance of a connection component. 
Destroys all owned components. 
Indicates that the component and its owned components are about to be destroyed. 
Calls message-handling methods for the object, based on the contents of the Message parameter. 
Checks if the current instance and the parameter are equal. 
Executes an action. 
This is the overview for the FieldAddress method overload.

Destroys an object and frees its associated memory, if necessary. 
Deallocates memory allocated by a previous call to the System::TObject::NewInstance method. 
Ensures that AComponent is notified that the component is going to be destroyed. 
Frees the interface reference for components that were created from COM classes. 
Returns a reference to the component associated by the implementing class. 
Returns a TComponent enumerator. 
Returns an integer containing the hash code. 
Retrieves a specified interface. 
Returns the entry for a specific interface implemented in a class. 
Returns a pointer to a structure containing all of the interfaces implemented by a given class. 
Returns a string used by the Object Inspector.

Returns the containing Component. 
Verifies whether the component has a parent. 
Determines the relationship of two object types. 
Initializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer. 
Establishes the component as the owner of a specified component. 
Returns the size in bytes of each instance of the object type. 
Indicates whether the component implements a specified interface. 
This is the overview for the MethodAddress method overload. 
Returns the name of a class method by address. 
Allocates memory for an instance of an object type and returns a pointer to that new instance. 
Opens the connection. 
Returns a reference to a specified interface if the object supports that interface. 
Establishes or removes internal links that cause this component to be notified when the implementer of a specified interface is destroyed. 
Removes a specified component specified from the component's Components list. 
Disables destruction notification that was enabled by FreeNotification
