• Why should I Use ASP.NET Membership security model?

  - by ListenToRick

  I'm updating my website at the moment and figure that if I am to update my login/security mode, now is a good time. I have looked through the Membership model which is included in ASP.NET but I'm convinced that it will provide any benefit apart from being familiar to other .NET deevlopers. There seems to be quite a lot of documentation for it, but little discussion for why its worth the effort. Can anybody shed some light upon this?

• Get CGI Fields from URL Python

  - by user299196

  When using the cgi module in Python, I can't seem to figure out how to extract CGI variables in the URL. For example if the url servercgi.py?name=user , how do I get 'name' after import cgi? For some reason, form.getvalue and form['user'] do not work but if I print the object, I see something like FieldStorage(None, None, [MiniFieldStoreage('name', 'user')]).

• Is there an alias for the local machine name in the Windows 7 login screen?

  - by Mikael

  We have many computers connected to a AD. The computers names is auto generated. When I want to log in using a local account, I have to figure out what the computer's name is, and log in using the following syntax: [COMPUTER_NAME]\local_account Now I'm wondering if there is an alias that I can use instead? So instead of logging in using NB-aw35sdds\local_account, I can use something like localhost\local_account.

  - by hora

  I have the following code: printf("num: %d\n", strcasecmp(buf, "h\n")); And I get the following results when I try plugging in different letters: a: -7 g: -1 i: 1 j: 2 h: 156 H: 156 Should strcasecmp not return 0 when buf is equal to H or h? Any ideas why it's returning 156? I need to figure out how to check whether the user types H or h. Thanks!

Can you please supply a code snippet for this case?

• How do you create a dropdownlist from an enum in ASP.NET MVC?

  - by Kevin Pang

  I'm trying to use the Html.DropDownList extension method but can't figure out how to use it with an enumeration. Let's say I have an enumeration like this: public enum ItemTypes { Movie = 1, Game = 2, Book = 3 } How do I go about creating a dropdown with these values using the Html.DropDownList extension method? Or is my best bet to simply create a for loop and create the html elements manually?

• Which comm ports exist? Win32

  - by myforwik

  On win32, using winapi, is there anyway to know which comports (from com0 upwards) actually exist as devices? At the moment I am just attemping to open them all (0 to 9), but I can't figure out the difference of failure between one not existing, and one not simply being available for use because someone else is using it. Both situations seem to return the same last error, so I was wondering if I could list all the comports available on the system.

• How do I get the scalaz IDEA live templates working for the symbolic methods?

  - by oxbow_lakes

  Many of the methods in scalaz have symbolic equivalents, such as forever and 8 (of course, I have this the wrong way round, the symbolic methods really have ASCII equivalents). The project contains a live templates XML file for IDEA so these can be auto-completed, I believe by using the forever+TAB shortcut (in the above instance). I can't figure out how to import this live template into IDEA and actually use it, though. How can I do that?

  I'm trying to figure out how much overlap there is between the different languages of the .NET framework, and what the real differences are. Is there an overlap of libraries/methods/functions...?

• Writing a DBMS in Python

  - by Matt Luongo

  Hey guys, I'm working on a basic DBMS as a pet project and planning to prototype in Python. I figure there's a reason there are only a few Python databases, and my gut agrees that my favorite language will be too slow to act as an honest performing database, but I'm looking forward to using it to learn what I need quickly. Would someone please contradict me? Is Python as ill-suited right now for this sort of thing as I think?
