[windows] vbscript output to console

I came across this post and went back to an approach that I used some time ago which is similar to @MadAntrax's.

The main difference is that it uses a VBScript user-defined class to wrap all the logic for switching to CScript and outputting text to the console, so it makes the main script a bit cleaner.

This assumes that your objective is to stream output to the console, rather than having output go to message boxes.

The cCONSOLE class is below. To use it, include the complete class at the end of your script, and then instantiate it right at the beginning of the script. Here is an example:

    Option Explicit

'// Instantiate the console object, this automatically switches to CSCript if required
Dim CONS: Set CONS = New cCONSOLE

'// Now we can use the Consol object to write to and read from the console
With CONS

    '// Simply write a line
     .print "CSCRIPT Console demo script"

     '// Arguments are passed through correctly, if present
     .Print "Arg count=" & wscript.arguments.count

     '// List all the arguments on the console log
     dim ix
     for ix = 0 to wscript.arguments.count -1
        .print "Arg(" & ix & ")=" & wscript.arguments(ix)
     next

     '// Prompt for some text from the user
     dim sMsg : sMsg = .prompt( "Enter any text:" )

     '// Write out the text in a box
     .Box sMsg

     '// Pause with the message "Hit enter to continue"
     .Pause

End With
