Cruise Control .Net vs Team Foundation Build |
|cruisecontrol.net|tfs|build|build-automation|continuous-integration| |
Our team is setting up nightly and continuous integration builds. We own Team Foundation Server and could use Team Foundation Build. I'm more familiar with CC.Net and lean that way but management sees all the money spent on TFS and wants to use it.

The point of mysql_real_escape_string isn't to protect against injection attacks, it's to ensure your data is accurately stored in the database. Thus, it should be called on ANY string going into the database, regardless of its source.
You should, however, *also* be using parameterized queries (via mysqli or PDO) to... |
Data binding is a bad idea? |

Another discussion (we've been having a lot of them these days!) in our work is whether data binding is a bad idea or not.
Personally, I think it is A BAD THING.
My reasons are thrice:

For a lightweight ORM that performs well and only requires a single assembly why not try out [Lightspeed][1] from Mindscape.

The storage class specifier controls the *storage* and the *linkage* of your variables. These are two concepts that are different.

For me, the big win with the naming convention of prepending an underscore to private members has to do with Intellisense. Since underscore precedes any letter in the alphabet, when I do a ctrl-space to bring up Intellisense, there are all of my _privateMembers, right at the top.

Double check that it is indeed a derivation of the UserControl class, not the WebControl one.

If you're building a hash table in which to store your vertices, I can think of a couple of ways to avoid collisions:

That is actually a very nice feature in VC++ (and I believe other compilers) because it allows you to see un-allocated memory for a pointer in the debugger. I will think twice before disabling that functionality. When you delete an object in C++ you should set the pointer to NULL in case something later tries to delete... |
Briefly, it is the mapping of the name you assign a variable to its address in memory, including metadata like type, scope, and size. It is used by the compiler.
That's in general, not just C[++]*. Technically, it doesn't always include direct memory address. It depends on what language, platform, etc. the compiler ... |

Something for other commenters to note - the question is about PL/SQL, not about SQL. Some of the answers have obviously been about SQL, not PL/SQL.

Tables are valid when you have a table of data. I've seen interactive grid widgets where they go out of their way to use a bunch of divs to avoid the dreaded table tag. When it's tabular data, make it a table.
