How to escape strings in workflow for Query

We have a workflow that does a query that was developed by a consultant.  I have recently discovered that it does not seem to escape the ' in the string that the user enters into a form.

 

Luckily this is only used internally so it should not be subject to malicious attacks.  However, I would like to fix it quickly.  What is the recommended way to escape strings that users input that are then put into querys?

  Hi James,

   

  At some point after your display form, you will want to use an Assign activity, and a string.replace to substitute a single quote, for a double single quote (not a double quote).

   

  For example:

   

  displayFormOut.ToString.replace("'", "''")

   

  I hope this helps!

   

  Thanks,

   

  Danny
