Using OLE Automation
with Symantec
pcAnywhere
This chapter includes the following topics:
■About OLE Automation
■About the pcAnywhere Automation Server
■What you can do with the pcAnywhere Automation Server
■Before you start
■Where to find more information
About OLE Automation
OLE Automation is a technology that lets you create an external application or
other development tool (such as a script or macro) that can control and
automate any exposed function within an application.
OLE Automation consists of the following components:
■OLE Automation server: An application or software component that exposes
its functionality so that it can be accessed or controlled by other
applications or development tools
The pcAnywhere Automation Server is an example of an OLE Automation
server.
See “About the pcAnywhere Automation Server” on page 12.

12 Using OLE Automation with Symantec pcAnywhere
About the pcAnywhere Automation Server
■OLE Automation controller: An application or development tool that
accesses and controls the components that have been exposed by the OLE
Automation server
You can use any programming language that supports OLE Automation.
The two most common programming languages are Microsoft Visual Basic
and Microsoft Visual C++.
An external application accesses an OLE Automation server by connecting to the
server and then requesting access to one or more of its published interfaces. An
interface is an entry point that allows access to one or more related methods or
properties. After an application obtains an interface to the server, it can then
call any internal interface method as though it were part of the external
application.
About the pcAnywhere Automation Server
The pcAnywhere Automation Server lets external applications manage
pcAnywhere remote, host, and caller information files to automate remote
control and file transfer tasks. The pcAnywhere Automation Server functions as
a programmable replacement for the Symantec pcAnywhere user interface and
mirrors much of its default behavior.
For example, when you create a host object in pcAnywhere, the first available
modem TAPI device is assigned by default. Similarly, when you create a host
object using the pcAnywhere Automation Server and then enumerate through
the list of assigned connections, the first available modem TAPI device is
already assigned.
What you can do with the pcAnywhere Automation
Server
The pcAnywhere Automation Server lets you automate a variety of
administrative and productivity tasks. For example, you can do the following:
■Automatically distribute and install software updates on multiple
computers across your network
■Schedule automatic file transfers between computers for audit or archive
purposes
■Automatically add a name to or remove a name from the allowed callers list
on every pcAnywhere host on your network

13Using OLE Automation with Symantec pcAnywhere
Before you start
This document contains several examples, written in both Visual Basic and
Visual C++, to illustrate how to connect to and use the pcAnywhere Automation
Server.
See “Visual Basic object definitions” on page 19.
See “Visual C++ object definitions” on page 69.
Before you start
During a connection to the pcAnywhere Automation Server and its interfaces,
identifier parameters, known as globally unique identifiers (GUIDs), are passed
to the automation library API functions. A separate GUID is assigned to the
pcAnywhere Automation Server and to each exposed interface. These GUIDs
must be present in the system registry to connect an external application to the
pcAnywhere Automation Server and its interfaces.
You can register the GUID entries automatically if you are running the external
application on a computer on which Symantec pcAnywhere is installed.
Otherwise, you must register the GUID entries manually.
See “Automatically registering the remote engine” on page 13.
See “Manually registering the remote engine” on page 14.
Automatically registering the remote engine
Before you connect to another computer for the first time using your OLE client,
you must self-register the remote engine. You can do this automatically when
you start a remote object in Symantec pcAnywhere.
To automatically register the remote engine
1To open Symantec pcAnywhere, do one of the following:
■On the desktop, double-click the Symantec pcAnywhere program icon.
■On the Windows taskbar, click Start > Programs > Symantec
pcAnywhere.
2In the pcAnywhere Manager window, click Remotes.
3Double-click a remote connection item.
This process registers the remote engine. You do not need to complete the
connection.

14 Using OLE Automation with Symantec pcAnywhere
Before you start
Manually registering the remote engine
If pcAnywhere is not installed on the computer on which you are running the
external application, you must register the GUIDs manually by running the
pcAnywhere Automation Server executable file (Winawsvr.exe). You only need
to run the executable file once to add the GUIDs to the registry. The
Winawsvr.exe file is located in the default Symantec pcAnywhere data
directory.
Accessing the pcAnywhere Automation Server
You can access the pcAnywhere Automation Server using any language
platform that supports OLE Automation. The two most popular language
platforms that support OLE Automation are Visual Basic and Visual C++.
The coding principles for these two platforms are similar, although in the Visual
Basic environment, much of the low-level work is performed behind the scenes
by the Visual Basic run-time system.
Accessing the pcAnywhere Automation Server with Visual Basic
The Visual Basic programming language has built-in support to interact with
OLE Automation servers, such as the pcAnywhere Automation Server. You
create a Standard Exe project, and then enter code in each method to access the
pcAnywhere Automation Server. Visual Basic takes the high-level method calls
in the source files and expands them internally into the corresponding low-level
OLE Automation method calls.
See “Visual Basic object definitions” on page 19.
To access the pcAnywhere Automation Server with Visual Basic
1Add a pair of Object variables for each pcAnywhere object that you want to
access.
For example, when working with remote objects, DIM a
RemoteDataManager and a RemoteDataObject as Object.
2Use the RemoteDataManager to attach to the remote object’s data manager.
For example, call the CreateObject method with
WINAWSVR.REMOTEDATAMANAGER as a parameter.
Visual Basic uses the textual parameter to locate the manager’s identifier in
the registry and returns the interface to that manager.
3Once there is a valid data manager object, use it to do any of the following:
■Determine the current directory.
■Change to another directory.

15Using OLE Automation with Symantec pcAnywhere
Before you start
■Enumerate the associated data object files in the current directory.
■Create, retrieve, or delete a data object file.
4After a data object is created or retrieved, you can get or set properties of the
object.
The Visual Basic syntax does not use a property’s name to differentiate
between getting and setting its value. Instead, the property’s position in
relation to the assignment operator determines whether the underlying
method call is a Get or a Set.
The following examples demonstrate a Get and a Set:
■To get an object’s phone number value, place the property name to the
right of the assignment operator.
For example, s = RemoteData.PhoneNumber(), where s is a string
variable.
■To set the phone number, place the property name to the left of the
assignment operator.
For example, RemoteData.PhoneNumber = “555-1212”
Accessing the pcAnywhere Automation Server with Visual C++
The pcAnywhere Automation Server uses type libraries to expose information
about its interfaces and methods to automation clients that are written in Visual
C++. These type libraries use Microsoft Foundation Classes (MFC), which can be
imported into your application using the Visual C++ ClassWizard.
The data manager classes that are provided in the type libraries provide the
functionality that is needed to obtain an interface to the pcAnywhere
Automation Server and perform high-level operations on the interface’s
associated object type.
Use the data manager object to do the following:
■Determine or change the current directory.
■Enumerate through the list of data object files in the current directory.
■Create, retrieve, or delete a named object.
Once created or retrieved, an object uses the associated data object class to
examine or modify any of its exposed properties. Most of these properties are
exposed through a pair of methods that begin with the word Get or Set. For
example, a user calls the GetPhoneNumber method to examine the object’s
current phone number property and calls SetPhoneNumber to set it.
See “Visual C++ object definitions” on page 69.

16 Using OLE Automation with Symantec pcAnywhere
Before you start
Importing and viewing classes
The pcAnywhere Automation Server uses the following type libraries:
■Winawsvr.tlb: Provides the information needed to connect to the
pcAnywhere Automation Server and access its interfaces
■Awrem32.tlb: Provides the information needed to control pcAnywhere
connections
Import and view classes
The following procedures explain how to import the class definitions from the
pcAnywhere Automation Server type libraries into your MFC application and
then view the classes that have been added to your application.
To import classes
1In Visual C++, create an MFC application.
2On the View menu, click Class Wizard.
3In the Class Wizard dialog box, click Add Class, and then click From a type
library.
4Double-click winawsvr.tlb.
5In the Confirm Classes dialog box, click OK to import all class definitions.
6In the Class Wizard dialog box, click Add Class, and then click From a type
library.
7Double-click awrem32.tlb.
8In the Confirm Classes dialog box, click OK to import all class definitions.
9In the Class Wizard dialog box, click OK to complete the import process.
The classes are added to the application. These classes let you manipulate
objects and manage connections.
Importing the class definitions from the type libraries also adds support
files to the application. These files contain the class definitions and
implementation source code for the pcAnywhere Automation Server.
See “Viewing the class definitions and implementation files” on page 17.
To view the added classes
1In Visual C++, open your MFC application.
2In the Workspace window, click the ClassView tab.

Viewing the class definitions and implementation files
When you import the pcAnywhere Automation Server type libraries into your
application, the following files are added:
■Winawsvr.h
■Winawsvr.cpp
■Awrem32.h
■Awrem32.cpp
These files contain the class definitions and implementation source code for the
pcAnywhere Automation Server. You do not need to edit these files; however,
each application source file that contains calls to the pcAnywhere Automation
Server methods must include Winawsvr.h.
To view the class definitions and implementation files
1In Visual C++, open your MFC application.
2In the Workspace window, click the FileView tab.
Launching host and remote OLE objects
Symantec pcAnywhere requires that you store all host and remote objects in the
default data directory. Before you launch a host or remote object that you
created using OLE, ensure that the object is located in the pcAnywhere default
data directory.
