Using Enums

Hi Guys,
Here are the useful methods that can be utilized against the Enums:

Public Enum WeekDays
     Sunday
     Monday
     Tuesday
     Wednesday
     Thursday
     Friday
     Saturday
End Enum

1. The following method helps easily to load the enum names to the combo/list box
Example:

lstWeekDays.Items.AddRange([Enum].GetNames(GetType(WeekDays)))

2. The following method helps easily to load all the enum values at once to an array
Example:

dim myArray as Array = [Enum].GetValues(GetType(WeekDays))

3. The following method helps easily to determine if a name or a value exists in the Enum
Example:

if [Enum].IsDefined(GetType(WeekDays), "Sunday") Then 'do something
If [Enum].IsDefined(GetType(WeekDays), 1) Then ' do something its Monday

Microsoft Code Analysis Tool .NET

Hi Guys,
CAT.NET is a snap-in to the Visual Studio IDE that helps you identify security flaws within a managed code (C#, Visual Basic .NET, J#) application you are developing. It does so by scanning the binary and/or assembly of the application, and tracing the data flow among its statements, methods, and assemblies. This includes indirect data types such as property assignments and instance tainting operations. The engine works by reading the target assembly and all reference assemblies used in the application -- module-by-module -- and then analyzing all of the methods contained within each. It finally displays the issues its finds in a list that you can use to jump directly to the places in your application's source code where those issues were found. The following rules are currently support by this version of the tool. - Cross Site Scripting - SQL Injection - Process Command Injection - File Canonicalization - Exception Information - LDAP Injection - XPATH Injection - Redirection to User Controlled Site. You can download this package here.
