for visual elements that tell us the page your app is done loading already

So we’ll look for visual elements that tell us the page or app is done loading, or ready.

you could wait for a specific element on a page like a picture or button but a

handy find image activity so let's

For that, we have the handy FindImage activity.

quickly make a new sequence and try it

So let's quickly make a new sequence and try it out.

out we'll add the find image action and indicate the image you would like to

We'll add the find image action, and indicate the image you'd would like to detect, by dragging

detect by dragging a selection marquee like so and that is actually all there

a selection marquee like so.

And that is actually all there is to it.

find image stops the execution process until that specific image is found or

Findimage stops the execution process until that specific image is found or the {timeout}

the timeout is reached whichever comes

first now let's add a message box to be notified when the image is found and

Whichever comes first. Now let's add a message box to be notified when the image is found.

before we've run the workflow let's leave the si P page so we can clearly

And before we run the workflow, let's leave the Sap page so we can clearly see the findimage

see the find image in action

so run and hmm that's earlier than

So run and… hmm, that’s earlier than expected.

expected maybe it somehow got confused

let's try to find the problem we'll add

Let’s try to find the problem.

a hilight action to see what was

We’ll add a highlight action to see what was detected.

It will give us the element that was found.

we can highlight a clipping region and elements or a selector will just use

We can highlight a clipping region, an element, or a selector.

here the element generated by the find

We'll just use here the element generated by the findImage

and we'll change the color to red and the time - two seconds for better visibility now let's see where the

problem is well don't I feel silly

Now let's see where the problem is. Well, don’t I feel silly.

didn't even notice it there let's remove

So there was nothing wrong with it after all.

with it after all this means we can delete this message box but we'll leave the highlight for now in case we need it

This means we can delete this message box, but will leave the highlight for now in case

we need it later.

so from here on it's familiar terra-tory add a click image to open the login

So from here on, it's familiar territory: add a clickimage to open the login window…

we are on the logon button.

with that information we can start automating we'll add a type action after

first we'll create two variables to hold the email address and the password

First will create two variables to hold the email address and the password.

and we'll give them some initial values for testing

And we’ll give them some initial values for testing.

since the email field already has focus we'll start with email then tab to go to the next field then

Since the email field already has focus, we'll start with: email, then tab to go to the next

password then three tabs because we want to reach the login button and add an

field, then password, then 3 tabs because we want to reach the login button.

enter to activate it that should be fine

And add an enter to activate it.

That should be fine. So let's see.

nothing happens while on this empty page but when we go to the SA P homepage the

bad solution because the modal window might take longer than the delay you set

It’s a bad solution because the modal window might take longer than the delay you set,

okay next up starting apps starting apps

Ok, next up, starting apps.

is pretty trivial even on virtual machines but we'll look at a few methods

Starting apps is pretty trivial even on Virtual machines, but we will look at a few methods,

from the simplest to the most demanding situation the first and most obvious one

is double-clicking a desktop icon you

The first and most obvious one is double-clicking a desktop icon.

can use a regular click image action to perform a double click on a certain icon

You can use a regular click image action to perform a double click on a certain icon.

just change the clip type from a single to a double click

Just change the click type from a single to a double click.

the problem with this method is that it can be a bit fragile if you're not

The problem with this method is that it’s can be a bit fragile if you’re not careful.

careful for example even selecting the icon can make it break down if the selection was

be easily fixed by making a better image selection one that doesn't include any

But that can be easily fixed by making a better image selection – one that does not include

portion of the background because that is what was different when the icon was selected

any portion of the background, because that is what was different when the icon was selected.

another better method of opening an app is by assigning it to a window shortcut key

Another better method of opening an app is by assigning to it a Windows shortcut key.

you can use any shortcut you like but it's safer to use more complex ones as

You can use any shortcut you like, but it's safer to use more complex ones, as it will

around with how would you start the notepad app itself one way of doing it

How would you start the notepad app itself?

is to use the Windows run command and

One way of doing it, is to use the windows Run command, and paste the application’s

paste the applications path that we can get from its shortcut

run now that's not very helpful maybe

Run. That's not very helpful.

you could avoid that by using the remote desktop app to send special commands but

Maybe you could avoid that by using the remote-desktop app to send special commands.

it looks like this version can only send a start menu command that is very useful

But looks like this version can only send a {Start menu} command.

too since we can type CMD and have a

That is very useful too, since we can type CMD and have a command prompt, from where

those are all fine and very similar to the method that I'm about to show you so

Those are all fine, and very similar to the method that I’m about to show you, so make

make sure you try them out if they're more suitable for your situation but for

belongs to the virtual machine from this gorgeous color scheme so let's quickly

You can tell it belongs to the virtual-machine from this “gorgeous” color-scheme.

see how to do all that in UI path

So let's quickly see how to do all that in UiPath.

starting with an empty sequence add in a click action for the maximize button

Starting with an empty sequence, add in a click action for the maximize button, and

and the send hotkey action for the win our shortcut you

a sendHotkey action for the Win-R shortcut.

let's see if that worked

Let’s see if that worked.

cool next let's mond open a certain file with the notepad app

Cool. Next, let’s type the command to open a certain file with the notepad app.

we'll make two variables one called app to hold the path for the application we

We’ll make two variables, one called App, to hold the path for the application we want

want to open and the other called arguments for the file and arguments we may use

to open; and the other called Arguments for the file and arguments we may use.

for the app initial value we'll just paste the notepad path we copied earlier

For the App initial value, we’ll just paste the notepad path we copied earlier.

and for the file we'll just put a dummy path

And for the file we’ll just put a dummy path.

in the type action will build the string to be typed in the run utility so app

In the type action we’ll build the string to be typed in the Run utility.

plus a space plus arguments

So: app, plus a space, plus arguments.

and an Enter key at the end to run it all

And an enter key at the end to run it all.

not bad it opened our test file

Not bad, it opened our test file successfully.

successfully and that's all there is to

And that’s all there is to it.

it if you need to you can add another click action to exit from full screen

If you need to, you can add another click action to exit from fullscreen.

and this brings us to the end of the

And this brings us to the end of this episode.
