And to you, Chris.

Thank you and the rest of the CP staff for making codeproject.com a nice place to hang my programming hat. The folks here and the articles they freely provide have helped me out more times than I can count. We do appreciate the hard work you, the staff, and the hamsters put in.

IP address exception

So I just spent an hour figuring out why I was getting an exception in my application when using a third party library to communicate to a credit card processing machine. I was getting a general exception back from the third party library, but the test software that comes with the library was working just fine.

Short answer, when I C&P'd my router's public IP address into the dialog box, there was a space at the end of the IP address. Took a while to spot:

"192.168.14.134 "
vs.
"192.168.14.134"

Sigh. OK, so now I make sure to trim the IP address string (the third party library expects a string) and I suppose I should do some regex validation.

Still, why couldn't I get back an exception like "malformed IP address"? Why is the library so sensitive to an space at the end of string? Yes, I take some responsibility, but not all the responsibility!!!

Yeah, now try other (valid) variants and see what their code does with them.

Edit:
A .net method/property which takes an IP address as a parameter should take a System.Net.IPAddress rather than a string.

Trim()
Seriously though...it seems really odd (terrible) that they didn't at least do a String.Trim() on the incoming string since it is such a freebie in almost every language (java, C#, javascript). Many more languages have it of course, but it is just named something slightly different.

I never trust user input because I used to do a lot of testing and open input boxes are the best way to break a program.

Yep, Little Bobby Tables. The newest on this one is real -- the guy who chose NULL for his license plate:

How a 'NULL' License Plate Landed One Hacker in Ticket Hell | WIRED[^]

Summary, every time a cop didn't have the license plate for the ticket a NULL got entered into the database for the license plate. That meant all ticket fines got assigned to the owner with the license plate of NULL. Cool | :cool:

err,
getting back to the OP message then...

if the guy was smarter he would have chosen (without the quotes) "NULL ", " NULL" or " NULL " as his plate.

(ya jus gotta find one of those forms where you enter each letter into a box - excuse for the last 2 "wanted it centered".

I faced something similar yesterday in one of my scripts. The string '1E2-' was validating as numeric...which it is...in hex! D'Oh! | :doh:

D'Oh! | :doh:

To be fair, if the expression had been entered correctly as either '1' (a single position) or '1E2:-' (an expression) it would have been OK. However, it should have reported the expression error (missing param separator) instead of saving the incorrect value. It was a 10 minute fix and I caught it before the customer! Smile | :)

Stringly typing never seems to get out of fashion.Strict typing can be a pain at times, but in the end it's one of your strongest allies. Taking the lazy way out breeds so many small and large horrors, but why waste a thought on it when they waste other people's time?

Those trailing space problems get worse when SQL Server gets involved, or the way we have it set up anyway. While a string with a trailing space is completely different to one without in .NET, TSQL matches them both. Causes a key-caching nightmare when not validated!

Not to mention that T-SQL will trim only character 32 and not other "whitespace characters".

And as a bonus, it does the same thing with VARBINARY, not just VARCHAR.

(LEN as well.)
