I am trying to create a grading system where you can choose your own subject and components(recitation, quiz etc) and as well as customize the formula... I will be using ddl language to create the fields and tables in the database so all's well with that, however, I have a big problem with the formula... I do not know how I can convert the string formula (from the textbox or the database) containing "variable names" into a workable formula that the system will recognize.
short example.
I declare three integers a, b & c with corresponding values (a =1, b=2, c=3). then let the user input a formula in a textbox.
example: textbox1: a+c
then equate the results using b...
this is where the problem lies, the program reads it as plain string and does not recognize the variable DX
How will I do this?
Some libraries which can evaluate simple math expression strings in .NET are:
Hope I helped!
