The table below provides summary descriptions of the procedures included in the Automation Library. For full descriptions, check the f90VB Reference Manual.

Procedure Name	Description
AddRef	Increase the reference-counter of an object.
CLSIDToProgID	Returns the Programmatic Identifier (ProgID) corresponding to the passed Class Identifier (CLSID).
ComInitialize	Initializes the COM library on the current thread and identifies the concurrency model as single-thread apartment (STA).
ComInitializeEx	Initializes the COM library on the current thread, sets the thread's concurrency model, and creates a new apartment for the thread if one is required.
ComUninitialize	Closes the COM library on the current thread, unloads all DLLs loaded by the thread, frees any other resources that the thread maintains, and forces all RPC connections on the thread to close.
CreateOleObject	Creates an instance of an OLE object, returning a variant containing a reference to the object's IDispatch interface.
CreateRemoteOleObject	Creates an instance of a remote OLE object, returning a variant containing a reference to the object's IDispatch interface.
EmptyParam	Returns a variant used to indicate an empty parameter in calls to f90VBAutomation subroutines.
EnumerateMembers	Enumerates the properties and methods exposed by an Automation object.
EventSinkConnect	Establishes a connection between an instance of a sink object and an outgoing interface of an Automation object.
EventSinkCreate	Creates an event sink object that can be connected to an outgoing interface of an Automation object.
EventSinkDestroy	Destroys (and disconnects) an instantiated Event Sink object.
EventSinkDisconnect	Disconnects a connected event sink object.
EventSinkEnumEvnts	Enumerates the events exposed by the outgoing interface of an Automation object.
EventSinkRegEvnt	Registers a Fortran function as the function to be executed when the event sink object receives an event from the Automation object to which the sink is connected.
EventSinkUnregEvnt	Un-registers a Fortran function associated to an event in a connected sink object.
ExceptionClear	Clears the fields and releases the BStrings contained in an Exception Information Structure.
ExecMethod	Executes a method exposed by an object.
GetActiveOleObject	Returns a variant containing a reference to the IDispatch interface of the active object for the class indicated in ObjRef.
GUIDToStr	Converts a Global Unique Identifier (GUID) into its string representation.
Invoke	Function Invoke can be used to execute methods, as well as to set or retrieve the values of the properties of an object.
NullGUID	Returns a null GUID structure. Null GUIDs have all their fileds set to zero..
OleInitialize	Initializes the COM library on the current thread and identifies the concurrency model as single-thread apartment (STA).
OleUninitialize	Closes the COM library on the current thread, unloads all DLLs loaded by the thread, frees any other resources that the thread maintains, and forces all RPC connections on the thread to close.
ProgIDToCLSID	Checks the registry and returns the ClassID (CLSID) of an Automation-capable object. If the object is not registered, an error condition occurs.
PropertyGet	Gets the value of the specified object's property.
PropertyPut/PropertySet	Set the value of the specified object's property. PropertySet is used only to set properties that receive values by reference.
Release	Releases the interface to an object, and unloads the object from memory if the reference-counter of the object reaches zero. This is the standard method to destroy objects created with subroutine CreateOleObject, CreateRemoteOleObject, CreateComObject and CreateRemoteComObject.
StrToGUID	Converts a string containing a GUID into its equivalent GUID structure.
