Classes

EOleError	EOleError is the exception class for low-level OLE errors.
EOleException	EOleException is the exception class for OLE automation errors that occur in methods or properties of an object.
EOleRegistrationError	EOleRegistrationError is the exception class for errors that occur when registering an OLE object.
EOleSysError	EOleSysError is the exception class for errors specific to the OLE IDispatch interface.
IServerExceptionHandler	Interface that allows you to report SafeCall exceptions that occur in a TComObject server to a third party.
TAutoClass	Class-reference type of TAutoObject.
TAutoIntfObject	TAutoIntfObject implements the IDispatch and ISupportErrorInfo interfaces.
TAutoObject	TAutoObject is a CoClass that supports the IDispatch interface, and that can be used as a base class for ActiveX Automation servers.
TAutoObjectEvent	TAutoObjectEvent adds connection point support to the TAutoObject implementation.
TAutoObjectFactory	TAutoObjectFactory is the class factory for TAutoObject.
TComClass	Class of TComObject.
TComClassManager	TComClassManager is the class type of the ComClassManager variable in the ComObj unit.
TComObject	TComObject is the base class for creating simple COM classes, such as those used for creating Shell extensions.
TComObjectFactory	TComObjectFactory is the type of the class factory object used to instantiate a TComObject class.
TComServerObject	TComServerObject is the abstract base class for TComServer.
TConnectionPoint	TConnectionPoint implements the IConnectionPoint interface for a single outgoing interface.
TConnectionPoints	TConnectionPoints implements the IConnectionPointContainer interface for a COM object that generates events on clients.
TTypedComClass	Class of TTypedComObject.
TTypedComObject	TTypedComObject supports the IProvideClassInfo interface and is the class type for COM objects that can provide the type information without requiring a type library to be loaded.
TTypedComObjectFactory	TTypedComObjectFactory is the type of the class factory object used to instantiate a TypedComObject class.

Routines

ClassIDToProgID	Returns the programmatic ID for a specified class given its class ID (CLSID).
ComClassManager	Returns a TComClassManager object.
CreateClassID	CreateClassID generates a new GUID and returns it as a string.
CreateComObject	Instantiates a single instance of a COM object.
CreateOleObject	Instantiates an Automation object.
CreateRegKey	Creates or opens a registry key that is a subkey of HKEY_CLASSES_ROOT.
CreateRemoteComObject	Creates a Com object on another machine and returns an IUnknown interface for it.
DeleteRegKey	Deletes a single key that is a subkey of HKEY_CLASSES_ROOT from the system registry.
DispatchInvoke	Calls the Invoke method on the specified IDispatch interface (Dispatch) using the specified call descriptor (CallDesc), dispatch IDs (DispIDs), parameters (Params) and result (Result).
DispatchInvokeError	Raises an exception using the specified OLE return code (Status) and exception information (ExcepInfo).
EventDispatchInvoke	Calls the specified Invoker with the specified dispatch ID (DispId) and parameters (ADistParams) as arguments.
GetActiveOleObject	Retrieves a reference to an IDispatch interface to a currently running, registered COM object.
GetDispatchPropValue	Returns the value of a property on an IDispatch interface.
GetRegStringValue	Retrieves a value stored under a subkey of HKEY_CLASSES_ROOT from the system registry.
GUIDToString	Returns a string representation of the specified global unique identifier (GUID).
HandleSafeCallException	Sets the information of the specified exception (ExceptObject) as the error information object for the current logical thread of execution.
InterfaceConnect	Connects an IConnectionPoint interface.
InterfaceDisconnect	Disconnects an IConnectionPoint interface connection that was previously made by the InterfaceConnect procedure.
OleCheck	Throws an EOleSysError exception if the result code indicates an error.
OleError	Raises an EOleSysError exception.
ProgIDToClassID	Returns the class ID (CLSID) GUID that corresponds to the string specified as the ProgID parameter.
RegisterAsService	Registers a COM object as an NT service.
RegisterComServer	Registers an in-process COM server with the operating system.
SetDispatchPropValue	Sets the value of a property on an IDispatch interface.
StringToGUID	Returns a global unique identifier (GUID) that is represented by the specified string.
StringToLPOLESTR	Returns the specified string as an instance of POleStr.

Types

TClassInstancing	UTClassInstancing determines how COM objects are instantiated.
TConnectEvent	Type of function to handle the OnConnect event of a connection point.
TConnectionKind	This is a tuple that contains possible values for the connection type.
TEventDispatchInvoker	Type of anonymous method that EventDispatchInvoke calls.
TFactoryProc	Type of anonymous class method that TComClassManager.ForEachFactory calls on factories associated with a given server.
TOleVariantArray	Array of instances of OleVariant.
TThreadingModel	TThreadingModel indicates how COM serializes calls to a COM object.

Variables

CoAddRefServerProcess	Function that increments a global per-process reference count and returns the current reference count.
CoCreateInstanceEx	Function that creates an instance of the specified class on the specified machine.
CoInitFlags	Specifies the level of threading support requested for a COM server .EXE.
CoInitializeEx	Function that initializes the COM library to be used by the calling thread.
CoReleaseServerProcess	Function that decrements the global per-process reference count and returns 0 if your server application should initiate its cleanup; it returns a non-zero value otherwise.
CoResumeClassObjects	Function that your server application (that can register multiple class objects) must call to inform the Service Control Manager about all registered classes.
CoSuspendClassObjects	Function that you can call to prevent new activation requests from the Service Control Manager on all class objects registered within the process.
