    Oh so noble of me. But there is some noble-ness in the underlying madness of the obvious. Ok, enough about the s. Just wondering if I should change my codeing to include the nullable type. It's like I've come to a cross road. Start using then from here on in and ill be stuck with them. It's not like something small either. It's like creating a new standard that ill be using from now on. Busy rewriteing my helper utility. Wondering if I should use them. ?? Help. ?? HElp ?? HELp ?? HELP

      Nullable or Not. That is the question. Are they good or are they bad? What are YOUR thoughts?

      The question should be: "When are they good and when are they bad?"

                bool areNullablesGood = ("the month".indexOf('R') >= 0); Well, that answers that.

                          They are good when you need a nullable type. Or, when you need compatibility with other platforms (while designing web services contracts, for example).

                          If you truly believe you need to pick a mobile phone that "says something" about your personality, don't bother. You don't have a personality. A mental illness, maybe - but not a personality. - Charlie Brooker My Photos/CP Flickr Group - ScrewTurn Wiki

                            Neither. You use the correct tool for the job. Nullable types are just another tool in the toolbox. They serve a specific surpose. I don't qualify them as "good" or "bad".

                                True. What ever is best for the job. Simple. easy. For some reason when I code, I sit for hours wasting time, trying to find the best way foward. I know there are always a handfull of ways to accomplish a given task. I'm just trying to find the "best",most effecient,simplest solution. Maybe that it. Time. Every ms counts. Oh well. Think it's just monday driving me up the wall. Thanks anyway.

                                      That seems pretty close to the truth, as (1) months have at most one capital letter (never an R), (2) and "the month" has none. :)

                                      The quality and detail of your question reflects on the effectiveness of the help you are likely to get. Show formatted code inside PRE tags, and give clear symptoms when describing a problem.

                                        MS access users are violated.

                                          True. What ever is best for the job. Simple. easy. For some reason when I code, I sit for hours wasting time, trying to find the best way foward. I know there are always a handfull of ways to accomplish a given task. I'm just trying to find the "best",most effecient,simplest solution. Maybe that it. Time. Every ms counts. Oh well. Think it's just monday driving me up the wall. Thanks anyway.

                                          Don't use them when you don't have to. Every time you call an API expecting a non nullable value you'll have to do validation/conversion of your nullables.
