COM and Automation Routines (W*32, W*64): table

Programs that use COM routines must access the appropriate libraries with USE IFCOM. Programs that use automation routines must access the appropriate libraries with USE IFAUTO. Some procedures also require the USE IFWINTY module.

The COM and Automation routines are restricted to Windows* systems.

Routine names are shown in mixed case to make the names easier to understand. When writing your applications, you can use any case.

Component Object Model (COM) Procedures (USE IFCOM)
Name Routine Type Description
COMAddObjectReference Function Adds a reference to an object's interface.
COMCLSIDFromProgID1 Subroutine Passes a programmatic identifier and returns the corresponding class identifier.
COMCLSIDFromString1 Subroutine Passes a class identifier string and returns the corresponding class identifier.
COMCreateObjectByGUID1 Subroutine Passes a class identifier, creates an instance of an object, and returns a pointer to the object's interface.
COMCreateObjectByProgID Subroutine Passes a programmatic identifier, creates an instance of an object, and returns a pointer to the object's IDispatch interface.
COMGetActiveObjectByGUID1 Subroutine Passes a class identifier and returns a pointer to the interface of a currently active object.
COMGetActiveObjectByProgID Subroutine Passes a programmatic identifier and returns a pointer to the IDispatch interface of a currently active object.
COMGetFileObject Subroutine Passes a file name and returns a pointer to the IDispatch interface of an Automation object that can manipulate the file.
COMInitialize Subroutine Initializes the COM library.
COMIsEqualGUID1 Function Determines whether two GUIDs are the same.
COMQueryInterface1 Subroutine Passes an interface identifier and returns a pointer to an object's interface.
COMReleaseObject Function Indicates that the program is done with a reference to an object's interface.
COMStringFromGUID1 Subroutine Passes a GUID and returns a string of printable characters.
COMUninitialize Subroutine Uninitializes the COM library.
Automation Server Procedures (USE IFAUTO)
Name Routine Type Description
AUTOAddArg1 Subroutine Passes an argument name and value and adds the argument to the argument list data structure.
AUTOAllocateInvokeArgs Function Allocates an argument list data structure that holds the arguments to be passed to AUTOInvoke.
AUTODeallocateInvokeArgs Subroutine Deallocates an argument list data structure.
AUTOGetExceptInfo Subroutine Retrieves the exception information when a method has returned an exception status.
AUTOGetProperty1 Function Passes the name or identifier of the property and gets the value of the Automation object's property.
AUTOGetPropertyByID Function Passes the member ID of the property and gets the value of the Automation object's property into the argument list's first argument.
AUTOGetPropertyInvokeArgs Function Passes an argument list data structure and gets the value of the Automation object's property specified in the argument list's first argument.
AUTOInvoke Function Passes the name or identifier of an object's method and an argument list data structure and invokes the method with the passed arguments.
AUTOSetProperty1 Function Passes the name or identifier of the property and a value, and sets the value of the Automation object's property.
AUTOSetPropertyByID Function Passes the member ID of the property and sets the value of the Automation object's property, using the argument list's first argument.
AUTOSetPropertyInvokeArgs Function Passes an argument list data structure and sets the value of the Automation object's property specified in the argument list's first argument.
1 These routines also require USE IFWINTY.
