At the bar
-
With a former coworker and another friend of ours:
Him: (developing an ASP.NET app for internal use) I was having problems detecting null values...
Friend: Uh, "is DBNull"?
Him: So I rolled my own.
Me: Oh, jesus.
Him: I just take every table in the database...
Friend: ...
Him: ...loop through every column...
Me: You're going to wind up on TDWTF.
Friend: Dude. "Is DBNull."
Him: ...convert it to an empty string, check the length...
Me: It's part of the framework!
Him: Works great.
Me: ...
Friend: ...I personally would love to see his take on "void Batman()". TRWTF is that he reads the site, but missed the correct way to check for null values...

You, your coworker and friend on another topic:
You: So, you're trying to have a baby? Him: Yeah, but she just isn't getting pregnant; I think the condoms are causing a problem Friend: Why don't you just stop using them? Him: But I found a great workaround: I prick each one with a pin before ...

o is DBNull
DBNull.Value.Equals( o )
o == DBNull.Value
( o as DBNull ) != null
try { o.ToString() } catch { /* NULL */ } /* NOT NULL */
for( int i = int.MinValue; i < int.MaxValue; i++ ) if( i == o ) { /* o is not null (or not an integer) */ }
o.GetType().FullName == "System.DBNull"Ad nauseam.

[quote user="joe.edwards@imaginuity.com"] for( int i = int.MinValue; i < int.MaxValue; i++ ) if( i == o ) { /* o is not null (or not an integer) */ } [/quote]
I meant: for( int i = int.MinValue; i < int.MaxValue; i++ ) if( i == o ) { /* o is not null */ } /* o is null or not an integer */
