solving math equations stored in strings 1

[FerretRunner2]

The question is whether it is possible for an equation stored in a string (that is written as an arithmetic operation that Visual Basic would accept) to be solved in Visual Basic. Specifically, whether a variable could be entered into the function (like if X represented where the variable should be used).

I have heard the question before, and have wanted to use it myself but until now have simply found a way around it. I would like to make a program that involves graphing several things, and being able to simplify an equation from a string that depends on a variable would quite useful. I would like to avoid performing string operations to separate it into parts, although, because that would be tedious and if that is the only solution, I will try finding a way around this.

Thanks for any help in advance.

Try adding a reference to the VBA library to your project. You should be able to pass your string to it, to be interpreted.

Eval may fit your needs.

Note: You must have Project reference to MS Access Library.

Thanks for the help, I got it working. I'm surprised it was that easy! (I used MS Access and Eval). Thanks also chiph, I just found that the MS Access was the easiest for me to figure out.
