How to determine which code is generated? "Invalid floating point value"

Question

I am using Delphi 2010 and have a program that continues to generate a dialog box with a message

'' is not a valid floating point value

How do I get delphi to show me the line that generated this error?

Answer 1

The easiest way to solve this is to run under the debugger and set it to Notify about language exceptions , Tools | Parameters:

Ignore the large list of ignore exceptions that come from my own code base. Just make sure the checked box is checked.
