Why would I want to do that?

You have to Functions & Recovery scenarios work with different actions Different actions = Different ORs

Do I know you? Can’t be sure…

You have to Can’t record certain objects Auto-hide panels Objects with changing hierarchies Nested inner-objects, Sub menus

You have to

Can’t record certain objects

Auto-hide panels

Objects with changing hierarchies

Nested inner-objects, Sub menus

Hold still, damnit! Even when you think you got it, all the properties turn out null

Simplicity Why kill a fly with an atom bomb? No need to use the OR for every one-time click button in the application

First, we need to better understand the Object Repository What the OR is How does the OR work

Well, yes, but under the hood, DP & the OR work the same way To understand the OR, is to understand DP

What is the OR?

A mysterious beast that records objects, in order to use them later

What is to record an object? Write down how to identify it

What is to record an object?

Write down how to identify it

Who are you? = How can I identify you?

Who are you?

Identification is done with properties and values

Identification is done with

properties and values

Who are you? = Your height = 400 Your title = “NotePad” You are visible (=True)

Who are you?

So, What IS the OR? Collections of properties & corresponding values Each collection represents an object No mysterious beast here

So, What IS the OR?

Collections of properties & corresponding values

Each collection represents an object

No mysterious beast here

OK, So what IS DP? DP is a way for specifying the properties & values without using the OR interface No mysterious beast here, either

OK, I get it, there’s nothing more than properties and values Can we get on with it?

How do I actually use DP? There are two ways

How do I actually use DP?

There are two ways

1 Throw the properties and values straight into a command

1

Throw the properties and values straight into a command

It’s the good old syntax you know, except the string between the () is not the OR name. It’s the property:=value identification string

That’s kinda restrictive What if I want to use multiple identification properties?

That’s kinda restrictive

What if I want to use multiple identification properties?

No problem: VBWindow(“height:=400”, “title:=New Document”).Maximize You can use as many properties as you like

No problem:

VBWindow(“height:=400”, “title:=New Document”).Maximize

You can use as many properties as you like

All fine and well, but what if I want to use regular expressions?

All fine and well, but what if I want to use regular expressions?

No problem: VBWindow(“title:=.*Document.*”).Maximize ID strings are automatically interpreted as regular expressions

No problem:

VBWindow(“title:=.*Document.*”).Maximize

ID strings are automatically interpreted as regular expressions

2 Throw the properties & values into a description object, and throw IT into the command

2

Throw the properties & values into a description object, and throw IT into the command

Here also, all the values are interpreted as regular expressions. To turn it off, use oDesc(“Property1”).RegularExpression = False

Method 1 is faster, best used for one or two commands, tops

Method 1 is faster, best used for one or two commands, tops

When you want to execute multiple commands on an object, method 2 is a better choice by far (allows one-time definitions, multiple uses)

When you want to execute multiple commands on an object, method 2 is a better choice by far

(allows one-time definitions, multiple uses)

You can use DP with OR VBWindow(“OR”).VBButton(“text:=OK”).Click Or (when oDesc is a description object): VBWindow(“OR”).VBButton(oDesc).Click

You can use DP with OR

VBWindow(“OR”).VBButton(“text:=OK”).Click

Or (when oDesc is a description object):

VBWindow(“OR”).VBButton(oDesc).Click

But , you can only start from OR, and move to DP So this will not work: VBWindow(“title:=notgood”).VBButton(“clickme”).Click

But , you can only start from OR, and move to DP

So this will not work:

VBWindow(“title:=notgood”).VBButton(“clickme”).Click

And that’s about it You can use each of the methods (or combine them), and you’ll be able to use objects that are not in the OR

Solving double objects When QTP finds two object which match the same description, it freezes This kinda sucks

DP has a magic property: “index”, which allows us to tell the double objects apart Index is a zero-based counter

Getting objects collections This feature is so cool, deserves a title on its own

THE coolest thing you can do with DP, is to get a collection of all the objects that math an identification

I don’t know who you are, or how many are you, but I want to mark all of you! Regular DP won’t help - Don’t know how to identify each checkbox

OK, this is indeed cool, but it only gets us the inner controls of a given window. Can we also get the application’s top level windows?

So, With DP we can work with no OR Sometimes we have to use it Other times it’s just more fun and useful DP also throws in a lot of extras that make it an inseparable part of good QTP automation Taste it, Experience it, Learn it, Use it, Love it It’s worth your while
