Obviously it gets more complicated if you need to quote/escape commas etc in the values. In that case I would suggest looking at the csv module in the standard library:

The benefit here is that it's very, very simple, and as safe as you getin C++. You can cast this, like RobQ suggests, but there's nothing you can do that would prevent someone from that if you're not c... |
How can I determine whether a given date is in Daylight Saving Time for a given timezone in .NET 2.0? |

I'm on .NET 2.0, running under Medium Trust (so [TimeZoneInfo][1] and the Registry are not allowed options). I'm asking the user for two dates and a time zone, and would really love to be able to automatically determine whether I need to adjust the time zone for DST.

What you want is read-only access without copying the entire blob of data. You have a couple options.
Firstly, you could just return a const refererence to whatever your data container is, like suggested above:

This has the disadvantage of concreteness: you... |

Start with a stronger password. (8 characters is still fairly weak)

I use pico or nano as my "casual" text editor in Linux/Solaris/etc. It's easy to come to grips with, and whilst you lose a couple of rows of text to the menu, at least it's easy to see how to exit, etc.

Since python is installed on nearly every non-Windows OS by default now, the only thing you really need to make sure of is that all of the non-standard libraries you use are installed.

One advantage of both @Shog9's and @RichQ's solutions is that they de-couple the client from the collection implementation.

You can store data in your page's `ViewState` dictionary
So in your Page_Load you could write something like...

ViewState["lastPic"] = lastPicNum;
you should get the idea. |
