Define Data Subtype Identification?
Define Data Subtype Identification?
The Parser that is part of the VBScript Scripting Engine automatically defines a variable’s data subtype
for you at runtime. However, there are times when the programmer may need to know the variable’s
data subtype. To determine the specific data subtype used, VBScript you can use any of the three
categories of functions to determine the data subtype:
• The VarType(variable) function which returns a code based on the Variant data subtype used
• Various IsXxxx(variable) functions which return boolean values indicating whether the variable
is of a specific data subtype.
• A TypeName(variable) function which returns a string based indicating the data subtype
what is Graphics Script?
what is Graphics Script?
The Graphics Script is located in the Graphics Worksheet folder. Procedures and Variables declared in
the Graphics Script interface are available locally but are not accessible by any Screen Script interface,
or from any other VBScript interface within IWS. Procedures and Variables declared in a Screen Script
interface are not accessible by the Graphics Script. If common Procedure(s) are required, they should
be put into the Global Procedures interface. Note that the Graphics Script is scanned (processed) by
IWS before the Screen Scripts.
what is XMLDOM?
what is XMLDOM?
XMLDOM is the XML Document Object Model that defines a standardized approach for creating,
accessing and manipulation XML documents. The DOM structures the XML document as a tree-like
structure (the node), with each node having elements, attributes and text. There is a root element,
which is the highest level element, and 0 or more child (sibling) nodes. Each node can also have 0 or
more child nodes.
A VBScript code segment can be created in an IWS application to allow creation, accessing and
manipulation of XML Documents. This allows passing of data between IWS and another computer in
XML format. Note that in addition to XMLDOM, ADO.NET also supports XML databases
what is WSDL?
what is WSDL?
Web Services Definition Language, or WSDL, is an XML-based language for describing network
services as a set of endpoints operating on messages containing either document-oriented or
procedure-oriented information. WSDL is frequently used in conjunction with SOAP (Simple Object
Access Protocol, a simple XML-based protocol for applications to exchange information using HTTP).
Common examples of WSDL are stock price, news services, weather information, currency conversion,
etc.
VBScript code in an IWS application can instantiate a SOAP client object through the following
statement:
