Tuto WINDEV 25

274 Part 4: Full application with data Overview In most cases, an XML Web service is defined as an application accessible via the standard Internet protocols. More specifically, Web services allow several computers connected via Internet to interact. Web services allow you to run procedures and processes on a remote Web server (.NET, SOAP or J2EE) from a client computer. With WINDEV, these Web services can be used as client, via the SOAP protocol on HTTP (the standard Internet protocol for transferring HTML pages), with the SOAPxx, DotNetxx and J2EExx functions. Regardless of the platform of the Web server (.NET, J2EE, ...), a Web service is accessible via the SOAP protocol. Remark With WINDEV, you don’t even have to be an expert in this field. A wizard takes care of ("almost") everything! Practical example A Webservice specific to the Tutorial allows you to check the different operations that can be performed on a Webservice. Integrated to the "WD Full Application" project, this Webservice is used to interrogate a supplier database to check whether a product is available (stock) from its reference. In a first time, the Webservice will be imported into the "WD Full Application" project then it will be used in the application to check the product availability from a Product form. Importing a Webservice ▶ Close the current project if necessary. The WINDEV home page is displayed. ▶ In the home page, click "Tutorial" and select "Full application (Exercise)".
