IntelliSense
The VBScript Editor provides a useful tool called IntelliSense, a feature first popularized in Microsoft
Visual Studio. Intellisense can be thought of providing “auto-completion” based on the language
elements, variables and class members, as well as a convenient listing of available functions. As the
developer
IntelliSense the dialog box can display the following:
• VBScript Functions
• ActiveX Controls, Properties and Methods (the ActiveX Control must be inserted on the Screen
where the Screen Script, Command Dynamic or ActiveX Event is used)
• IWS tags and tag fields.
• IWS built-in functions
As the programmer begins to type and characters are recognized, IntelliSense may turn on. If not, the
programmer can activate IntelliSense by pressing the Ctrl key plus the Spacebar (“Ctrl” + “ “). By typing
a “$” at the beginning of a line, this allows access to IWS tags and built-in functions to be referenced.
When IntelliSense is activated, a pop-up box will appear. The contents of the pop-up box depend on
what the programmer has already typed. Sample IntelliSense pop-up dialogs are shown below:
IntelliSense Dialog for
VBScript Functions
IntelliSense Dialog for
IWS Functions
Note that VBScript variables are not accessible through the IntelliSense dialog box.
IntelliSense uses different Icons to indicate the type of item that is being referenced. Some Icons are
used to indicate different items, so it is important to notice what object is being referenced (i.e. is it an
IWS tag, ActiveX Control, VBScript function, etc.)
