Question

What are the main steps to create a web-based application?

Answer

Perform the following steps to create a web-based application:
- Develop the application locally. Don’t use features that are not supported by Web Thin Clients (like Group of
Screens) for the screens which will be saved as HTML format;
- After saving the screens in the standard format (File → Save), save the screens which must be available for the
Web Thin Client in HTML format from the File → Save as HTML menu;
- Open the Project Settings dialog window (Project → Settings menu) and select the Web tab;
- Configure the Data Server IP Address field with the IP address of the Server station (station where Studio is
running);
- Configure the path to the web files in the URL field. The web files are saved in the Web subfolder of the
application. This path will vary according to the web root of your Server station (for example:
http:///);
- Open the Project Station dialog window (Project → Status menu), select the Execution Tasks tab and set the
TCP/IP Server module as Startup=Automatic;
- Open the application tags database and set to the Server option instead of Local in the Web Data column for all
tags that must exchange value between the Server and the Web Thin Client station;
- Execute the Tools → Verify Application command to update the Project Settings in the HTML files;
- If there is no Web Server running in the computer, copy the program NTWebServer.exe from the BIN folder of
Studio into the web root (for example: Web) and execute it. The path where this Web Server
program is executed will be the web root of the station. The Web Server is necessary to export data (web files) in
HTTP protocol to the Web Thin Clients;
Execute the application in the Server station;
- Using a browser (for example: Internet Explorer v4.1+SP1 or newer version) in the Web Thin Client station, type
the URL address to download the screen which had been saved in HTML format (for example:
http:///.html).
ï?€ Note: The Web Thin Client requires an Active-X component (ISSymbol.ocx) to handle the screens on the browser.
If the Web Thin Client is connected to the Internet, this component is downloaded and registered automatically.
Otherwise, you must copy it to the System32 directory of the Web Thin Client and register it by
executing the regsvr32 ISSymbol.ocx command. This file can be found in the BIN folder from the Studio
installation directory.
