Introduction
Thinfinity ® VirtualUI™ is a software solution that enables developers to add user
interface web remoting to their Windows applications. Typically adding one line of code
to the application's project, you can transform your Windows Application into a crossplatform one, enabling it to run as usual on Windows or as a Web application when
installed under a Thinfinity® VirtualUI™ Server environment.
Why Thinfinity® VirtualUI™?
1. It enables you to create dual-platform Windows/HTML5 Apps, effortlessly.
2. It expands application's availability by delivering them instantly to users
anywhere on any device.
3. It dramatically reduces the Total Cost of Ownership (TCO), by slashing IT
costs and simplifying administration avoiding costly virtualization/remoting
solutions such as Citrix XenApp® or Microsoft™ RemoteApp.

Thinfinity® VirtualUI™ UI 1.0
3. Select the environments to be installed:
Thinfinity ® VirtualUI™ Server
Thinfinity® VirtualUI™ Server is an HTTPS/WebSocket Server that maintains the
communication between your app and the Web Browser. Installing this
environment will enable you to configure and run your adapted Windows apps.
This is not needed for development purposes but its installation is recommended
for testing purposes.
On this installation mode, the Thinfinity® VirtualUI™ Server will be installed as a
Windows Service.
Development Environment
This environment is meant to be installed on the developer machine. This
mode installs the Thinfinity® VirtualUI™ SDK files that you will need to
include or reference in your application's project. It includes also one
Thinfinity® VirtualUI™ Server that will execute in a "development mode", to
quickly test your application from a Web Browser.
4. Press Next and wait for the installation process to finish. When it is done, press
the "Finish" button.

3.2
Compiling and testing a WinForms application
To integrate a .NET
WinForms application with Thinfinity® VirtualUI™ follow these
steps:
1. Open Microsoft Visual Studio.
2. Open the application's project you want to integrate with.
3. Right-click on the 'References' node and select 'Add Reference'. Click 'Browse'
and find Cy be le .T hinfinit y .V irt ua lUI.dll assembly, which is typically located in c :
\Progra m F ile s\T hinfinit y \V irt ua lUI\De v \dot Ne t \.
4. In the program.cs file add a line as follows:
using System;
using System.Windows.Forms;
namespace MyApp
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Cybele.Thinfinity.VirtualUI.Instance.Start();
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}

}
5. Compile your program and run it.
6. Observe on the Windows Task Bar that the Thinfinity® VirtualUI™ Development
Server icon will appear.
7. Right-click on the icon, and after that click on the "Open" menu.
A Web browser window will open and your application will be running inside.
If you don't want the debugging mode to start a new Thinfinity ® VirtualUI™ Server or
want to specify the port in which it will start, you can change the DevServer property to
reflect that change. You may also configure Thinfinity ® VirtualUI™ to open a new
browser window as soon as you run your application.

Compiling and testing a Delphi application
To integrate a Delphi VCL application with Thinfinity® VirtualUI™ follow these steps:
1. Open Delphi.
2. Open the application's project.
3. Add the V irt ua lUI_Aut oRun unit to the 'Uses' clause of the project source file.
This unit will typically be located in the C:\Progra m F ile s (x86)
\T hinfinit y \V irt ua lUI\de v \De lphi folder.
program MyApp;
uses
Windows,
Forms,
VirtualUI_AutoRun,
MyApp.Main in MyApp.Main.pas' {Form1};
{$R *.res}
begin
Application.Initialize;
Application.C reateForm(TForm1, Form1);
Application.Run;
end.
4. Compile the program and run it.
5. Observe on the Windows Task Bar that the Thinfinity® VirtualUI™ Development

Accessing the app from the Web
Follow the next
steps to access registered applications using the Web Browser:
1. Open your preferred Web Browser.
2. Type in the Thinfinity® VirtualUI™ Server url. Typically http://your-machine:6580.
3. Enter your username and password, if required.
4. If you have registered only one application, Thinfinity® VirtualUI™ Server will
connect you directly to that application.
5. If you have registered more than one application, you will see a home page which
lists all the registered applications to pick from.
a. Check the 'Open in a new browser window' option if you want the application
to be opened in another tab.
b. Click on the corresponding icon of the application you want to access.

Managing the SSL Certificate
An SSL certificate is an effective way to secure a website against unauthorized interception
of data. At its simplest, an SSL Certificate is used to identify the website and encrypt all
data flowing to and from the Certificate holder's web site. This makes all exchanges
between the site and its visitors 100 percent private.
A valid SSL certificate is included with the Thinfinity® VirtualUI™ Server installation and all
communications are already encrypted with the product's default certificate. You may want
to create your own certificate to identify your company better.
Managing the SSL Certificate
1. There are two forms of creating your own SSL certificate:
a. Create A self-signed certificate
b. Use A CA Certificate
2. Once you already have your certificate files, go to the Thinfinity® VirtualUI™ Server
Settings 'General' tab.
3. Click on the 'Manage Certificate' option.
4. On this screen you should inform the location of the certificate files, as follows:
Certificate File
Inform the path to the certificate file.
CA File
If the certificate is issued by a unknown CA, you should fill in the pathname to the CA
certificate.
Private Key
You should inform the pathname to the certificate private key file.
Pass Phrase
Inform the password, if there is any, used when the private key was generated.
Note: The path names can be absolute (C:\MyCertPath\UserThisCert.pem) or relative to
the path where Thinfinity® VirtualUI™ Server is installed (\cert\UserThisCert.perm).

The Default Embedded Certificate
A certificate called "self-signed.pem" is included with the Thinfinity® VirtualUI™ Server
installation. You will find it inside the \cert directory, located inside the Thinfinity® VirtualUI™
Server application path.
If you want to use this default certificate you should have the files set as the image
below:
You'll find these settings inside the Thinfinity® VirtualUI™ Server Settings 'General'
tab, by clicking on the 'Manage certificate' button.
Because this certificate is not issued by a known C ertificate Authority (C A), the web
browsers will warn you they can not verify its authority.

Thinfinity® VirtualUI™ UI 1.0
In order to integrate Thinfinity® VirtualUI™ into your web page you will be required to
modify the HTML page by adding some Javascript code.
From this point on, we consider you have already installed and configured Thinfinity®
VirtualUI™. If not, go back to the Getting Started topic.
To learn how to use the SDK library, read the following topics:
Deploying
Modifying the HTML file
Connect method
Authentication Scheme
SSL Certificate
Take a look also on the sdk.html file available in the Thinfinity ® VirtualUI™ server
installation directory, under the folder Thinfinity ® VirtualUI™. After configuring the
profileKey parameter on the connect method, you can try it out from the browser
through the address
http(s)://server_IP:port/sdk.html.

Thinfinity® VirtualUI™ UI 1.0
Modifying the HTML file
You need a remote application container in your web page. This can be either:
A div element
An iframe element
A new browser window
You will be able to configure this through the connection mode (step 6b explained
further below).
Modifying your html file, step-by-step:
1. Open the HTML page for editing.
2. Add these meta tags into the <head> tag:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="X-UA-Compatible" content="chrome=1"/>
3. If you want the Thinfinity® VirtualUI™ integration to work with iOS, add the
following <meta> tags into the <head> tag.
<link rel="apple-touch-icon" href="images/icon.png"/>
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="viewport" content="width=device-width, initial-scale=1.0,
maximum-scale=1.0, minimum-scale=1.0, user-scalable=no, targetdensityDpi=device-dpi"/>
4. Add a reference to the css stylesheet files into the <head> tag. These files must
be deployed with your website/application.
<link rel="stylesheet" type="text/css" href="css/popups.css"/>
<link rel="stylesheet" type="text/css" href="css/webfmx.ui.css"/>
5. Add the following libraries inside the <head> tag:
a. The jQuery library (jquery.min.js):
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/
jquery.min.js" type="text/javascript"></script>
b. Point a script tag to the Thinfinity® VirtualUI™ SDK client library (sdk.min.js): this
file will have to be deployed with your website/application. The tag below should be
added to the <head> section, too.
<script src="sdk.min.js" type="text/javascript"></script>
©2014 by Cybele Software, Inc.
SDK Reference
69
6. Also inside the <head> tag, add one more <script> tag. The GetW ebFM X method
creates the object that handles the Thinfinity® VirtualUI™ SDK functionality. It has two
arguments: the Thinfinity® VirtualUI™ server URL and the connection mode in which
Thinfinity® VirtualUI™ SDK will work. The con n ect method is the method that creates the
application and positions it on the structure you have configured (div, iFrame, Window).
<script type="text/javascript">
function connect() {
window.scroll(0, 1);
var ThinfinityVirtualUI = GetWebFMX("Thinfinity VirtualUI
server URL", connection mode);
ThinfinityVirtualUI.connect({
divId: 'WebFMX',
profileKey: 'Substitute with profileKey if using Access
Profiles'
}
});
};
</script>
a. Substitute the "Thinfinity VirtualUI server URL" argument, that goes inside the
GetW ebFM X method, with the Thinfinity® VirtualUI™ protocol + IP + Port following
this format example https://127.0.0.1:8443.
b. Substitute the second argument with the mode you want the connection to be
established:
Mode
Local
(remote
=false)
Remote
(remote=true)
How it works
The application is embedded in the same page inside a div
structure.
The sdk.min.js posts into Thinfinity ® VirtualUI™ Server.
With this mode you can place the application inside an iFrame or
a new window tab.
c. Find out the next sub-topic ("Connect method") how you should complete the
arguments that go within the connect method.
6. Code special behaviours on the available Thinfinity® VirtualUI™ SDK events.
7. Use the Authentication Scheme to ensure the usernames and passwords
security.

Thinfinity® VirtualUI™ UI 1.0
Connect method
The "connect" method creates the application and places it on the specified html
structure. In order to do so, it expects a JSON object as argument in which you can
inform all the desired settings. If you want to understand exactly how each setting will
influence on the connection, read the following topics:
Placement parameters
Application parameters
Settings parameters
Event parameters
Right bellow, you will find the connect method with all the possible parameters set.
They should not be sent all together, because each mode and environment will require
a different JSON object setup.
The Placement parameters will be required depending on the connection mode
(remote or local).
The Application parameters will configure which application and the authentication
information generated previously.
The other parameters (Settings and Events ) are optional and should be sent
whenever you need to change a determined Thinfinity® VirtualUI™ behavior.

Parameters
When it is triggered
reconnecting
This event is fired during the
server connection
establishment.
The reconnecting argument
informs whether this is a
reconnection or a first-time
connection.
-
Anytime the Web client is
about to be disconnected, the
"onQueryDisconnect" will
be triggered. It is intended
to validate with the user if
the disconnection is desired.
-
The "onServerConnect" event is
fired every time a "connect"
command is exchanged between
the browser and the
Thinfinity® VirtualUI™ Server.
It is a way of making sure the
server received a sent
"connect" command.
-
errMessage
-
This event
the client
started on
VirtualUI™
will be fired when
session has been
Thinfinity®
Server.
If an error prevents the
client connection to be
established, this event will
be fired. The errMessage
argument brings the error
message.
Anytime the Web client gets
disconnected from the
Thinfinity® VirtualUI™ Server,
the "onServerDisconnect" will
be fired. It could be
triggered because the
connection was lost
incidentally or also because
the user disconnected from the
server on purpose.

Thinfinity® VirtualUI™ UI 1.0
Authentication Scheme
This SDK is intended to embed an application within an existing website/application.
In this multi-application context, the authentication process involves two steps that
were designed to ensure the security of the exchanged data among the different
applications components:
1. Generating an authentication key from the website/application server side
2. Validating this key from the application client side, before starting the application
(connect method).
©2014 by Cybele Software, Inc.
SDK Reference
5.5.4.1
77
Generating the key
The one-time authentication key is a temporary key generated by Thinfinity®
VirtualUI™ Server, intended to protect the actual username and password. Both key
and password are temporary data and they will be only valid for a single connection
and limited period of time.
How it works:
1. First you need to ask Thinfinity® VirtualUI™ Server to generate the key and
password for you. Call the server following this URL format:
http(s)://Thinfinity® VirtualUI™ Server:Port/ws/oturl/get?
<queryString>
2. The queryString should be built with all parameters listed below:
username= <username> &password= <password> &plen= <passlen>
&expires= <expires>
Find on the table below a description for each required parameter.
Parameter
Description
username
This is the username to be authenticated on
Thinfinity® VirtualUI™ Server.
password
The password of the user to be authenticated.
plen
expires
This parameter carries the returned unique
password length.
Through this parameter you can set an
expiration(in minutes) for the key-password
pair. Expires = 30 means that the pair won't
work anymore after 30 minutes have passed from
the pair generation.
3. If Thinfinity® VirtualUI™ gets to authenticate with the sent parameters, it
will return a JSON object containing the One-Time key/password pair.
Parameter
Description
valid
Use this result to know whether the
authentication was successful (username and
password were valid).
key
This is the one-time key to be used for the
client side authentication.
pass
©2014 by Cybele Software, Inc.
This is the password to be used for the client
side authentication.
78
Thinfinity® VirtualUI™ UI 1.0
4. If the authentication was successful, write on the end HTML file the
generated key and password information, so that they can be used for the
client-side key/password Validation.
JavaScript example:
This is a JavaScript example. The actual Ge t One T im e Ke y method should be
translated to the Server side programming language and only invoked from there to
avoid username/password exposure on the client side.
function GetOneTimeKey(username,password) {
var otkey = getOneTimeKey(username, password);
if (!otkey.valid) {
alert('Invalid username/password');
}
return otkey;
}
function getOneTimeKey (username, password, passlen, expires) {
var returl = "";
if (!passlen) passlen = 8;
if (!expires) expires = 30;
$.ajax({
url: "http(s)://Thinfinity® VirtualUI™ Server:port" + "/
ws/oturl/get?username=" + username + "&password=" + password +
"&plen=" + passlen + "&expires=" + expires,
async: false,
dataType: "html",
statusCode: {
200: function (data) {
returl = eval("("+data+")");
}
}
});
return returl;
}
©2014 by Cybele Software, Inc.
SDK Reference
5.5.4.2
79
Validating the key
After you have generated the one-time key and password on the server side and have
written them on the HTML file, you should call the IsOnTimeKeyValid method from the
client-side. This method checks whether this authentication credentials are valid and
opens a new Web client session, using Ajax.
After invoking this method, you will be able to call the Connect method, responsible to
create and place the application on the HTML container.
JavaScript example:
function ValidateOneTimeKey(key, pass) {
ThinfinityVirtualUI.isOneTimeKeyValid(
key,
pass,
function () {
connect();
},
function () {
alert('error');
}
);
}
Parameters:

Thinfinity® VirtualUI™ UI 1.0
SSL Certificate
When you embed Thinfinity® VirtualUI™ into a website and the browser can not verify
the configured certificate authenticity, your integration will not work.
There are two ways of handling this issue:
1. Using your own certificate
If you already have your own certificate or if you will get one from a Certificate
Authority (CA) , the only thing you will have to do is configure the certificate as
described on "A CA Certificate" section.
2. Using the HTTP protocol
Otherwise, you should configure the Thinfinity® VirtualUI™ protocol to HTTP. This
setting is available on the Thinfinity® VirtualUI™ Manager General tab.
Keep in mind you will have to change the protocol on the GetThinfinity® VirtualUI™
server parameter as well.

Customizing the Web Interface
Thinfinity® VirtualUI™ allows you to modify the web interface and tailor it to
your branding scheme.
Customizing the application logo and other image files can be very simple, once
it only requires you to have the new image file and tell the application where it
is located.
Customizing the structure and style of the application may be a little bit more
complex. These kind of customizations have to be done at a programming level
(HTML and CSS).
Read also how to protect the customized web files in the Files Location topic.
©2014 by Cybele Software, Inc.
Appendix B - Tailoring the interface
7.1.1
93
Changing the logo
Modifying the application logo can be as simple as copying the new logo image and
telling Thinfinity® VirtualUI™ application where it is located:
1. Create a folder called "BrandingFiles", if it doesn't exist yet, under the folder web
located inside the Thinfinity® VirtualUI™ installation directory.
(e.g.: C:/Program Files/Thinfinity® VirtualUI™/web)
2. Copy your own logo image file to the "BrandingFiles" folder.
3. Create the WebAliases.ini file and configure it:
a. Create a file called "WebAliases.ini" in the installation directory (e.g.: C:/
Program Files/Thinfinity® VirtualUI™/WebAliases.ini). If the file already exists,
only append the lines to it.
b. Configure the redirection of the logo files you want to substitute, following the
two examples below (Thinfinity_Virtual_UI_150.png.png and favicon.ico):
[Alias]
;=================
;Main logo
;=================
/images/Thinfinity_Virtual_UI_150.png.
png=BrandingFiles\MyLogo.png
;=================
;Favicon
;=================
/favicon.ico=BrandingFiles\MyFavicon.ico
c. Save it.
4. Open the application to see the changes.
Take into account:
a. Any line in the "WebAliases.ini" file starting with a semicolon will not be
considered by the application. It can be used to leave comments in the file.
b. You can substitute any interface image or file, by following the same steps
described above.
c. Sometimes the favicon is not shown right the way, because the browser keeps
history of the images. In that case, you should clean the browser cache before
trying out the changes.

7.1.2
Thinfinity® VirtualUI™ UI 1.0
Customizing the web files
To customize the web files, you should:
1. Create a folder called "BrandingFiles", if it doesn't exist yet, under the folder
web located inside the Thinfinity® VirtualUI™ installation directory. (e.g.: C:/
Program Files/Thinfinity® VirtualUI™/web)
2. Make copies of the original web files that you want to modify to the
"BrandingFiles" folder. Copy only the files to be modified without their associated
folder structure.
3. Customize the files (html, css, etc) as you prefer.
4. Create the WebAliases.ini file and configure it:
a. Create a file called "WebAliases.ini" in the installation directory (e.g.: C:/
Program Files/Thinfinity® VirtualUI™/WebAliases.ini). If the file already exists,
only append the lines to it.
b. Configure the redirection to the files you have modified, by adding a line
similar to the examples below for each modified file:
[Alias]
/index.html=BrandingFiles\my_index.html
/css/index.css=BrandingFiles\my_index.css
c. Save it.
5. Open the application and check out the changes.
Take into account:
a. Any line in the "WebAliases.ini" file that starts with a semicolon will not be
considered by the application. It can be used to leave comments.
b. The paths located in the HTML, CSS, and other contents will be kept relative to the
original file location. This means that you won't have to change the content paths
when customizing this files.
©2014 by Cybele Software, Inc.
Appendix B - Tailoring the interface
7.1.3
95
Files Location
We recommend that a new folder be created in order to keep the customized files
instead of having them with the original files. This will enable you to:
a) Get back to the original interface configuration at any time.
b) Make sure that your files will be safe after a version upgrade.
You can also choose to place the files inside or outside the webroot structure. Keep
reading to see how each option will behave:
Storing the customized files in the webroot directory:
In this case:
1) The files will be externally accessible from a URL similar to: https://127.0.0.1/
BrandingFiles/customizedFile.html
2) The file paths, indicated in the "WebAliases.ini", can be relative to the webroot
directory. (e.g. "/img/Thinfinity_Virtual_UI_150.png.png=BrandingFiles\MyLogo.
png"). You will find other relative path examples on the topics Changing the logo
and Customizing the web files.
Storing the customized files outside the webroot directory:
In that case:
1) The files will be protected, because it won't be possible to access the customized
files from a URL.
2) The file paths, indicated in the "WebAliases.ini", must be absolute, as in the
