WINDEV Concepts

192 Part 7: Appendices WD OLEDB Used to access external databases via OLE DB. WD OPC UA This example shows how to communicate with an OPC UA server. WD OPC Presents the implementation of OPC protocol in WINDEV. WD OpenGL Allows you to interface OpenGL and WINDEV. OpenGL is a software interface used to draw three-dimensional objects (3D). WD OSD OSD means: On-Screen Display. It is the name given to the interfaces that appear on the computer or television screens for example. They are often used to perform settings. These types of menus are displayed above all the elements found on the screen. This example explains how to create this type of interface in WINDEV. WD PC Info Used to find out the language of the computer on which the application is run. WD Persistence This example presents the use of InitParameter, LoadParameter, SaveParameter. These functions are used to configure the backup of controls, variables and parameters. WD PivotTable This example presents the use of the Pivot Table control. This Pivot Table control is used to display dynamic statistics by performing groupings. These statistics are calculated from the database. WD PowerPoint Generation This example explains how to generate a PowerPoint presentation from: • the data found in a WINDEV application such as the data found in tables, charts. • and from a base PowerPoint document (.pptx). WD PowerShell This example allows you to run a powershell script from a WINDEV application and retrieve the result and the report. WD Printing TreeViews Allows you to print a TreeView. This example uses a “TreePrnt” class that can be easily re-used in any treeview control. WD Python This example shows how to run Python code in WINDEV applications. WD Queries Allows you to perform calculations, to pass parameters or to print the result of a SQL query on a HFSQL data file. WD Reflexive link Uses a “reflexive” link to manage the family trees: each person has several parents and several children All these records are stored in the same file.
