Window control The ActiveX control is used to easily manage the ActiveX technology. The ActiveX controls are reusable components that use the ActiveX technology and that can be included in a window. Creating an ActiveX control To create an ActiveX control: - On the "Creation" tab, in the "Other controls" group, click "Active X".
- Click at the desired location to create the control. The control appears in the editor.
To view the characteristics of the control, select "Description" in the context menu. If your application uses an ActiveX control, you must take the following into account: - 32-bit ActiveX controls can only be used in 32-bit applications.
- 64-bit ActiveX controls can only be used in 64-bit applications.
the editor must be in ActiveX mode. A 32-bit ActiveX control can only be edited in a 32-bit version of WINDEV. - the ActiveX must be installed according to the setup procedure on the user computer (see the documentation about the ActiveX if necessary).
- the wd300ole.dll DLL and the WINDEV application must be installed at the same time on the user computer.

Training (WINDEV): WD OPC
[ + ] This example presents the implementation of the OPC protocol in WINDEV. OPC means OLE for Process Control. It's a standard implementation based on OLE/COM for managing physical devices (robots, alarms, captors, ...). For more details, see the WINDEV help or the following site: http://www.opcfoundation.org/ WINDEV allows for data access through Automation or ActiveX (OPC DA Auto 2.0 specification). The use of OPC in WINDEV requires the use of an Automation object or of an ActiveX that serves as an OPC client layer. This Automation object or ActiveX is usually provided by the manufacturer of the device. Therefore, OPC in WINDEV is implemented using the basic principle of object automation and ActiveX.
