I am trying to create a procedure which will evaluate a string expression as if it were a line of code...Kind of like what a graphing calculator does when you enter a formula. Does anyone have any experience with this in VB? I have an example of C++ code which uses CodeDom, but I am a bit rusty with my C++!
I am using the given code to copy my database files...it works like a charm in debug mode but as soon as I create a setup, it stops working. The error is

I have a string 17:55:88 I want to split this up into the three sections and store them in varibles.IE I would like to have the 88 stored in a varible the 55 in a varible and the 17 in a varible.the following code does what i want, but i dont know how to put the results into their own varibles.
Don't know if I phrased the question right, but Say if you had a form named Form1, and on that form you declared a varible like Dim s as Integer = 0, how do you not refer to that varible when you reference a public sub on that form.
Reason for asking, I stepped through my code and noticed if I call Form1.CalculateField() to calculate some values, my calculations where wrong because the value of s was set to lets say 10 before I launched the second form which I call the above from, any how long story short, when the formm is referenced from another form, it evaluates all varibles declared, which means s was set back to 0.
