Function from the Built-in Scripting Language
When you type the name of an ActiveX control that is inserted on the screen followed by the dot character ( . )
on any VBScript interface from the screen where the ActiveX object is inserted, a list box will automatically
open with the list of all properties and methods from the object:
The items are displayed in alphabetic order, and each item has an icon to identify its main type, as follows:
Icon
Type
Property from the ActiveX object
Method from the ActiveX object
Parameter Quick Info
The Quick Info option displays pop-up boxes with the information about the functions from the Builtin
Scripting Language. The information includes all the parameters supported by this function, with the
currently configured one in bold text.
Complete Word
Complete word finishes a tag, member, field, function, or ActiveX property/method name once you have
entered enough characters to disambiguate the term. After you type the first few letters of the name, you can
press Ctrl+Space to complete the name automatically.
VBScript Compared to VBA
While VBScript and Visual Basic for Applications (VBA) are similar and are both based on the Visual Basic
standard language, there are advantages to using VBScript for IWS users:
• VBScript is supported for the Microsoft Windows Embedded operating system, and VBA is not.
• VBScript brings active scripting to a wide variety of environments, including Web client scripting in
Microsoft Internet Explorer. This prevents operations that may present risks for the Thin Client user, such
as direct access to local files.
• VBScript was designed to be simple and easy to learn, with some standards from VBA modified in
VBScript to make it more straightforward. For example, in VBScript the user does not have to worry about
the type of each variable when declaring them because VBScript assumes the proper type for each variable
automatically.
The following table lists VBScript features that VBA does not have.
