C# Invoke particular EventHandler in InvocationList

I am trying to get particular EventHandler get fired.

Event ProjectChanged was hooked by several EventHandlers

public static event EventHandler ProjectChanged;

foreach (var eventHandler in ProjectChanged.GetInvocationList())

{

    if (eventHandler.Method.Name == "UserContext_ProjectChanged")

    {

        eventHandler.DynamicInvoke(null,null);

    }

}

String to Guid in C#

public static Guid StringToGUID(string value)

{

    // Create a new instance of the MD5CryptoServiceProvider object.

    MD5 md5Hasher = MD5.Create();

    // Convert the input string to a byte array and compute the hash.

    byte[] data = md5Hasher.ComputeHash(Encoding.Default.GetBytes(value));

    return new Guid(data);

}

I love working in the shell. Mastery of shell lets you get things done in seconds, rather than minutes or hours, if you chose to write a program instead.
In this article I’d like to explain the top one-liners from the commandlinefu.com. It’s a user-driven website where people get to choose the best and most useful shell one-liners.

PYTHON iterate all files in a directory

To iterate through all the files within the specified directory (folder), with ability to use wildcards (*, ?, and [ ]-style ranges), use the following code snippet:

PLAIN TEXT

PYTHON:

1. import os
2. import glob
3.  
4. path = 'sequences/'
5. for infile in glob.glob( os.path.join(path, '*.fasta') ):
6.     print "current file is: " + infile

If you do not need wildcards, then there is a simpler way to list all items in a directory:

PLAIN TEXT

PYTHON:

1. import os
2.  
3. path = 'sequences/'
4. listing = os.listdir(path)
5. for infile in listing:
6.     print "current file is: " + infile
   
   

PYTHON RuntimeError: maximum recursion depth exceeded in cmp

if your python code produces the following error: “RuntimeError: maximum recursion depth exceeded in cmp,” try adding this line to the beginning of your code:

sys.setrecursionlimit(1500)

note that python’s default limit is 1000.
