VBScript OS Design Development (Windows CE 5.0)
The VBScript functionality for Microsoft® Windows® CE provides a run-time engine for parsing and translating Microsoft Visual Basic® Scripting Edition.
Microsoft VBScript®, a subset of the Visual Basic programming language, is a fast, portable, lightweight interpreter for use in Internet browsers and other applications that use Microsoft ActiveX® Controls, Automation servers, and Java language applets. Effective with Windows CE .NET 4.2, supports two optional functionalities:
- Script authoring, which enables DHTML Dynamic Properties, through the SYSGEN_VBSCRIPT_AUTHOR Sysgen flag.
- MsgBox and InputBox user interface, through the SYSGEN_VBSCRIPT_MSGBOX flag.
Script debugging is not supported, and Windows CE does not include type libraries for script interfaces.
Hosting for VBScript is provided by the Browser Control Host (SHDOCVW) in Internet Explorer 6 for Windows CE. The mobile Internet browser, Microsoft Pocket Internet Explorer, cannot host VBScript. However, you can create your own host application by using Microsoft ActiveX Scripting, which enables a host to compile scripts, obtain and call entry points, and manage the namespace available to the developer.
