the sender’s address If it is not found (.EOF is set), the sender is not a

For a real mailing list, you usually want to set the Sender to the person who

contributed the message and set a separate SMTP Reply-To field to the

address of the mailing list Readers can then see the contributor’s name, but

set the Reply-To To work around this problem, you put the sender’s email

address into the body of the message I leave it as an exercise for you to

implement this functionality by replacing the set

oNewMessage=oSession.Outbox.Messages.Add with set

oNewMessage=CreateObject("CDONTS.NewMail") (Don’t forget to set

oMessage=nothing after each message is sent.)

For proper operation of the list, you should open each attachment in the old

The sendNotice function sends a notification message as a reply to the

sender It reports on subscription status or the reason why the message was

not sent out It follows the standard method to send a message Note that it

The method Logon([ProfileName], [ProfilePassword], [showDialog], [newSession],

[parentWindow], [NoMail], [ProfileInfo]) is quite different Because you must log on to a profile, you give the ProfileName and ProfilePassword Set showDialog to True if you

want a dialog box to be shown to help the user to select a profile By default, Logon will attach to an existing session if one is already running from Outlook or another program Set newSession to True to always establish a new session Here is an example of the

Day 20: Using WSH with Custom VB and Java

By now, you’ve seen how powerful the Windows Scripting Host can be The scripting

languages themselves provide useful functionality Coupled with the built-in Windows scripting host objects, you can perform an infinite variety of useful automated tasks If the WSH objects aren’t enough, you can always use objects provided by other software

input dialog boxes This chapter shows you how to create objects using Visual Basic

WSH to Access Databases Through Microsoft Active Data Objects (ADO)" and Day 17,

"Using ADO for WSH Scripting Tasks," how it can be used to call Microsoft Active Data

Trang 16

For the first example, you’re going to develop a Visual Basic object that allows you to

display an Enter Password dialog box The object that you create will be basic It will

return true if the user clicks OK or false if the user decides to cancel.

The Visual Basic object will be implemented using two pieces A Visual Basic class will

provides space to enter a username and password, and to click an OK or Cancel button The Visual Basic class is what you will access from your WSH script; it hides the

implementation details of the form that you use to display the input dialog When you

Password properties As far as the sample script is concerned, it has no idea that the form exists.

This example assumes some familiarity with Visual Basic We are going to cover the

steps involved in assembling the object, but we aren’t going to discuss the details of

MaxButton to False; change MinButton to False; then change the

StartUpPosition to 2-CenterScreen Next, add controls to the form.

the Caption to &Password:.

Next you need to add text boxes that allow the user to enter his name and

property to "" and change (Name) to txtName Add another text box for the

password, set Text to "", change (Name) to txtPassword, and set

All that's left is to add OK and Cancel buttons At the bottom of the form, add a

button and set the Caption to &OK, the (Name) to cmdOk, and Default to true Add another button next to the OK button, and set the Caption to &Cancel, the (Name) to cmdCancel, and the Cancel property to true.

class, add the following code:

Trang 21

WSHLogin Change the project properties by choosing Project, WSH Login

Properties from the menu Set Project Type to ActiveX DLL and then click OK Save the project by choosing File, Save Project You can save the parts of the project

After you’ve saved the project, switch to the Login form Your screen should look like Figure 20.9.

Trang 22

GetLoginDetails, which are exposed by the class.

Visual Basic class The new public properties will be available the next time

Using the Login Details dialog from WSH is simple All you need to do is create an

WSHLogin.clsLogin, which represents the object Then you can call the

GetLoginDetails() function to display the dialog shown in Figure 20.11.

Trang 24

For the next example, you’re going to develop a Java object using Microsoft Visual J++ 6.0 that allows you to display an Enter Password dialog box that is identical to the dialog box in the preceding Visual Basic example Like the Visual Basic object, it will provide username and password properties and the getUserDetails() function.

Also like the Visual Basic example, the Java example will be implemented using two

pieces The Login class will provide the object interface for the object, and the

LoginForm class will provide the user interface.

Before you go through the example, be forewarned that the ActiveX/Java

integration is a capability provided specifically by the Microsoft Java

Virtual Machine You can’t use these techniques with the standard Java

This example assumes some familiarity with Visual J++ You are going to cover the

steps involved in assembling the object, but you aren’t going to discuss the details of

coding using Visual J++.

each field, simply add a label and an edit box As you get more experienced,

no matter the language, it can be used just the same as any other COM object.

Trang 32

You can extend the Windows Scripting Host using any language that provides the

capability to create COM objects In this chapter, you used Visual Basic and Visual J++

to create objects that you can use from within WSH scripts The custom objects allow you to present a better, more functional user interface than you can present using the

If you want to distribute scripts that use the custom objects that you’ve built, you need

to create an installation program for the custom objects The installation program

ensures that the object is registered on the user’s machine with all the correct DLL

of the organization Do the computers in your organization meet the hardware and

software requirements for Microsoft Windows Script Host? Do you know how to deploy Windows Script Host to users who don’t already have it? What about scripts; do you

know the best way to run scripts on users’ computers? On this, the 21st day of this

book, you will

If you were planning to deploy a new operating system to hundreds or thousands of

seats, you would plan and test carefully You should Don't take deploying Windows

Script Host or your scripts quite that seriously First, treating this process as a major

deployment costs a lot of loot and, beyond cost, you're unlikely to convince

management that you need a team to help you write specifications and deploy a handful

That doesn't mean that you shouldn't be smart about deploying Windows Script Host

and scripts With a bit of forethought, deploying the required files can be a process that

is business as usual In all cases, while sitting at your own desk, here are some steps to

Determine what you need to deploy—Do you need to deploy a new version of

Windows Script Host? Do you need to deploy a script? Make sure you have a handle

on which versions of which files you need to deploy (a topic you learn more about in this chapter).

Determine to whom you need to deploy—Are you deploying to all users in the

organization or just some groups or some users? Who are they? For example, if

accounting is using an outdated version of Windows Script Host but you want to use the new features of version 5.0, target that particular group.

Determine how you’re going to deploy—This chapter presents a number of

alternatives for deploying Windows Script Host and scripts Choose the alternative that

is best for the files you're deploying and your target Don't go overboard, however For instance, using Microsoft Systems Management Server to deploy a script to 10 users

is overkill You would be better off walking around with a floppy disk.

If you have an aptitude for journalism, you might be asking yourself what happened to

the when and where part of who, what, when, where, and how Considering the

deployment advice you learn in this chapter, timing doesn’t mean much You’re not

going to bog the network down with this deployment and, in most cases, you’re going to

deploy as part of users’ logon scripts That leaves the where Part of the process you

learn in this chapter is creating network shares from which users’ logon scripts install

files You also learn, later in this chapter, about directory conventions that make sure

Part of your deployment planning should be testing your scripts In many

organizations, network administrators get a reputation for shutting down

the server at the wrong times and breaking computers with faulty software, among other things Don’t let a buggy script add fuel to the fire.

Windows Script Host, and thus your scripts, will run anywhere a suitable (32-bit

Windows) operating system will run Thus, if a computer runs Microsoft Windows 98

well, the host will run well on that same computer If a computer runs Microsoft Windows

95 with Microsoft Internet Explorer 4 well, the host will also run well.

To clarify the requirements for Windows Script Host, examine the hardware

requirements for each Microsoft operating system Windows 95, Windows 98, Windows

NT Workstation 4.0, and Windows 2000 Professional have many requirements in

common They all require a VGA or better resolution monitor and a mouse or similar

pointing device None require a CD-ROM drive, but all are less cantankerous if one is available Processors and memory are different stories, however No version of 32-bit Windows runs well on anything less than a Pentium or compatible processor Windows

95 and Windows 98 require at least 32MB of memory to avoid tapping the user’s

patience, but 64MB makes for a better experience Windows NT Workstation 4.0 and Windows 2000 Professional are nothing short of doggish on a computer that doesn’t

have at least 64MB of memory, but you’ll go from ho-hum to wow on a computer with at least 96MB.

additional space The disk space requirements for the host and your scripts should

never really be an issue, however, because a healthy computer always has far more

All 32-bit versions of Windows, except Windows 95, meet the minimum software

requirements for Windows Script Host To install Windows Script Host in Windows 95, however, you must install OSR2 or install Internet Explorer 4 or better On computers without either, you can still install Windows Script Host version 5.0, the latest version, if

you install DCOM DCOM, which stands for Distributed Component Object Model,

allows COM components (ActiveX controls, scripts, and so on) to communicate across networks.
