You will learn how to use the GUI designer, the DataWindow technology, the RESTClient component and the deployment tool. You will also see how to test and debug your web application in the browser.
To create a web application with Powerbuilder 115 57, you need to follow these steps:
Create a new project: Launch Powerbuilder 115 57 and select File > New > Project. In the New Project dialog box, enter a name for your project, such as "WebAppDemo". Select Web Application as the project type and click OK. A new project will be created and added to your workspace.
Create a database connection: In the System Tree, right-click on Database Connections and select New. In the New Database Connection dialog box, enter a name for your connection, such as "DBConn". Select ODBC as the connection type and click Next. In the ODBC Data Source Name dialog box, select an existing data source that points to a database that contains a table named "customer". Click Next and then Finish. A new database connection will be created and added to your project.
Create a DataWindow object: In the System Tree, right-click on DataWindow Objects and select New. In the New DataWindow Object dialog box, enter a name for your object, such as "dw_customer". Select SQL Select as the data source type and click OK. In the Database Painter, select your database connection from the drop-down list and expand the Tables node. Drag and drop the "customer" table to the SQL Painter. Select all the columns from the table and click Retrieve. A DataWindow object will be created and populated with data from the table.
Create a user interface: In the System Tree, right-click on Windows and select New. In the New Window dialog box, enter a name for your window, such as "w_main". Select Main Window as the window type and click OK. A new window will be created and opened in the Layout Painter. Drag and drop a DataWindow control from the Controls toolbar to the window. In the Properties panel, set the DataObject property of the DataWindow control to "dw_customer". Resize and position the DataWindow control as you like.

Click Add Parameter again and enter "appid" as the name and your API key as the value. You can get an API key from [OpenWeatherMap]. Click Test to send a GET request to the web service and receive a JSON response that contains weather information for Brussels.
Create a script: In the System Tree, double-click on w_main to open it in the Script Painter. In the Script panel, select cb_1 from the drop-down list of controls and clicked from the drop-down list of events. This will create an empty script for the clicked event of cb_1, which is a command button that is automatically added to every main window. Enter the following code in the script editor: // Declare variables string ls_temp double ld_temp // Call RESTClient object rc_weather.sendrequest() // Get temperature value from JSON response ls_temp = rc_weather.getresponsebody() ld_temp = Double(JSONGet(ls_temp,"main.temp")) // Convert temperature from Kelvin to Celsius ld_temp = ld_temp - 273.15 // Display temperature in a message box MessageBox("Temperature", String(ld_temp) + " C")
This code will call the RESTClient object that you created earlier, get the temperature value from the JSON response, convert it from Kelvin to Celsius and display it in a message box.
