VBScript Reference Manual for InduSoft Web Studio

InduSoft Web Studio VBScript Reference Manual
ActiveX Control Name
established by IWS. You
can rename this Control.
Use this interface to tie
Properties and Methods to
IWS tags.
To access the ActiveX Control’s Properties and Methods from VBScript, you simply type the name of
the Control, followed by a Period “.” and then the Property or Method. You will need to reference
documentation from the developer of the ActiveX Control to determine which properties are setting (Set)
or retrieving (Get), and the functioning of the Methods available. For example, with the Microsoft scroll
bar control, we access Properties using the following code:
MFSC1.Min = 0 ’ Set the min value of the scroll bar to 0
MFSC1.Max = 100 ’ Set the max value of the scroll bar to 100
$LocTag = MFSC1.Value ’ Get the current location of the scroll bar, pass to IWS tag
IWS tools such as Position and Command can be used with ActiveX controls. To enable these tools,
insert the ActiveX control on the Screen and then make sure the ActiveX control is selected
(highlighted). Then, select the Position or Command tool. For example, with the Position tool, you
can control the visibility of the ActiveX Control, or change its location on the screen.
Key Notes:
• All ActiveX Controls must have a unique name
• When referencing an ActiveX object name that has been inserted on a screen, note that
the reference is case-sensitive from VBScript for IWS 6.1 SP1 or earlier.
• Only ActiveX Properties and Methods can be accessed via VBScript. Event handling
must be set-up by configuring the object (i.e. right click on the object)
• ActiveX Controls can only be accessed by VBScript interfaces associated with the
Screen which contains the ActiveX Control (i.e. Screen Script, Command Dynamic,
ActiveX Event Handler)
