Re: native .NET Microsoft Script Control ? (particularly eval method)

#1

Hello,

You can use VSA technology to have native support for VB.NET and JScript.NET
in .NET applications.
have a look to the following urls:

It works great - it even compares string expressions. I just would
prefer a native .NET version over COM if at all possible.

Sample code:

Dim scriptControl1 As New MSScriptControl.ScriptControl
Dim sExp As String
scriptControl1.Language = "VBScript"
Textbox1.Text = ""
sExp = "12 + 3 * 10"
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf
sExp = "(`abba` < `bagel`)"
sExp = Replace(sExp, "`", Chr(34))
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf
sExp = "(`red` < `bagel`)"
sExp = Replace(sExp, "`", Chr(34))
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf
sExp = "((1*5)*5)"
sExp = Replace(sExp, "`", Chr(34))
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf
sExp = "( (`abba` < `bagel`) and true) or ( ((1*5)*5) = 25 ) "
sExp = Replace(sExp, "`", Chr(34))
Textbox1.Text += sExp & " = " & scriptControl1.Eval(sExp) & vbCrLf

VSA is no longer a recommended technology. Its marked obsolete in version
2.0

there currently is no replacement or offical roadmap.

Thanks for your reply. What replaces VSA? How can you do jscript or
vbscript evaluation in your .NET apps without compiling on the fly?
Isn't that a bit kludgey?

Hi,

Some time ago I was playing with the JScript.NET engine to execute code
without compiling it first, but I don't remember how it was exactly. It
had something to do with setting the "il" option of the VsaItem in
question to false, but I don't have the full code at hand.

HTH,
Stefan
