Properties and methods of the ActiveX

An ActiveX is associated with properties and methods. These properties and methods can be used in WLanguage to handle the ActiveX control directly. To do so, use the Automation syntax of WLanguage.

For example:

// AVIReader is an ActiveX control
AVIReader>>Zoom=12 // Assign a property
AVIReader>>Pause(10) // Call a method

To find out the properties and methods associated with an ActiveX, you can:

see the documentation of the ActiveX control.
use WDXVIEW supplied with WINDEV.
use the automatic completion of WINDEV. The properties and methods of the ActiveX are automatically proposed by the code editor. For example, for the "Microsoft WEB Browser" ActiveX, we get:

Events associated with the ActiveX

WLanguage allows you to manage the events generated by an ActiveX control with ActiveXEvent. This function allows you to associate a procedure of your project with the requested event.

For example:

// Initialization code of the ActiveX control named AVIReader
ActiveXEvent("My_procedure","AVIReader","OnClick")
// "my procedure" will be called whenever the
// "OnClick" will be triggered by the "AVIReader" control.

To find out the events associated with an ActiveX, you can:

see the documentation of the ActiveX control.
use WDXVIEW supplied with WINDEV.
