18. What is the purpose of the “VBS” function in comparing two strings?
The “VBS” function is used to compare two strings and report the same results as the “StrComp” function.
It uses the “MsgBox” statement to display the result with an information icon and success title.
19. What is the difference between a “Sub Procedure” and a “Function Procedure” in VBScript?
A “Sub Procedure” is a reusable code that can be called multiple times from a main script or driver script, but it does not return a value.
A “Function Procedure,” on the other hand, is also a reusable code that can be called multiple times, but it returns a value that can be used in the main script or driver script.
20. What is the purpose of a procedure in scripting?
A procedure is a powerful tool in scripting that saves time, reduces testing time, and promotes modularity. It allows for the creation of reusable code within a procedure, making it easier to test and call the procedure with confidence.
21. How do you call a sub procedure in VBS script?
A sub procedure can be called in VBScript using a call statement, giving the name of the procedure and arguments within parentheses (), or providing a list of arguments as a comma-separated list.
22. What are the advantages of using a procedure in VBS script?
Using a procedure allows for multiple calls to the same procedure in the main script or driver script, and changes can be made at one place within the sub procedure without having to make the change at any other place.
23. How do you create an HTLM report using a VB script?
To create an HTLM report using a VB script, you can use variables such as OBJFSO and OBJFile, which execute the ‘Create Text File’ method on the file system object.
