Properties
HelloMessage
Methods
SayHello
The sample the following features:
- Supports dual interfaces which allows access of automation properties and
methods through vtable binding and through IDispatch.
· Provides Rich Error information for vtable-binding controllers. This is does
by implementing ISupportErrorInfo and using IErrorInfo.
· Implements active object registration using RegisterActiveObject and
RevokeActiveObject. · Implements correct shut-down behavior. · Includes a .reg file
which contains Hello.Application and Hello.Application.2 as progIDs. · When
created for automation, is invisible initially.
To compile: -----------
Requires OLE 2.02 or later. Use the external makefile called makefile to
compile. In Win16, run the WXSRVER.EXE from \OLE2\BIN before running the makefile.
The makefile invokes mktyplib.exe that reads hello.odl and creates the type
library, hello.tlb. It then compliles the source files.
To run: -------
Change hello.reg to provide the full path of hello.exe and hello.tlb.
Register hello.reg in the registration database by double-clicking it. The HELLCTRL
directory contains a controller that will control HELLO using vtable-binding.
Files: ------
HELLO.ODL Object description language that describes the property and method
that HELLO exposes.
TLB.H Header file generated by mktyplib.exe MAKEFILE Makefile for
project.
Other files implement the HELLO automation server.
