Execute function

[Byron Hopp]

Is there a way to execute a function from a text representation of the
function.

Like,

Dim strFunction as String
strFunction = "Now()"

Is there any function, or process I can call and pass to it strFunction
where when it executes it will return what Now() returns?

Thanks,

Byron...

Yes, using Reflection:

Dim objType As Type
Dim d As DateTime
Dim objResult As Object

objType = d.GetType()

objResult = objType.InvokeMember("Now",
Reflection.BindingFlags.GetProperty, Nothing, d, Nothing)

MessageBox.Show(objResult.ToString)

Hah! I was going to post something very similar to this topic last week!
Fortunately, I waited and found another way to do it as I didn't want to
execute a "string", always frowned upon doing things like that. But, I'm
glad that now I know how to do it for future reference.

Thanks,
