I am receiving this error message: "Input string was not in a correct format." on my ASP.net 2.0 VB project.
When looking at other posts with this error its obvious that each time it will be specific to the users' project. Therefore my main question is, is it possible to generate a more informative error message?
I am already in debug mode but it does not tell me in which string the problem lies. I am converting some strings to integers with "Cint" and have also tried the Integer.Parse() method to no avail.

I am trying to write a program that reads values from a datafile and makes the data available in an array for further use in the program. The data consist of a description and then a value (COM_PORT=COM1, for example). My idea is to put the data in an array so that I can just search the array for COM_PORT and I will get COM1 back. Is that a good approach of handling it this way? What methods would I use to put the data (I use FileSystem.ReadAllText, the data is in a string) into an array? Would the split method work?
View 2 RepliesI'm having an issue with a page I created that was working fine two months ago. Nothing has changed in structure of the SQL tables and I have even done an insert within SQL to the table and all works fine with SQL. So the problem lies within the code. I'm getting this error:

This is worse due to the fact that nowhere in the project does it use "ParseDouble". I believe that this has something to do with the objectfactorylibrary but can't pin anything down.
The object of this project is to create code for a 4 function calculator that takes a character string like: 5 + 123 + 6 = and generates a new string: 134 There are multiple tasks to be done. First the string must be broken into tokens; in this case, there are 6 tokens:
