Convert a string to code

[Andrew Cranwell]

Hi,

I wanted to know if it is possible to convert a string into a code
expression, like you can with JavaScript's 'Eval' statement.

For example,

If I have a string such as "Dim A As New RandomObj()", can I turn this into
code in some way?

Many thanks,

Andrew

No, not really. What you request is a feature typically available in
interpreted (scripting) languages. VB.NET is typically a compiled language
and thus doesn't provide intrinsic support for dynamically evaluating code.
However, it's actually possible to execute code dynamically at runtime:

Addendum:

.... and if you want to dynamically execute JScript code:
