Multiple lines of code in chrome console

There are times when you need to run some code on your page to see how some changes would look. Or maybe just mess about on a friends computer. Nevertheless you might not be able to do all your console operations with just one line at a time.

So how do you run multiple lines of code in the Chrome debugger console?
Turns out you can just create a function:

And once you have declared your function, you run it.

Watch that UTF8 when serving JSON

Im currently messing about with Node.JS after deploying a droplet on DigitalOcean.  Heard alot of people talking about DigitalOcean before, but never tried it untill now. That server was so incredibly simple to set up, i'm speechless.

I will post a guide on how to quickly get multiple node sessions running in a bit, but for now i will just mention this little detail i ran across. I had a bit of a head-scratcher when writing my first Node service for serving up some Json data. It worked nice and dandy, but coming from Norway my Json data contains alot of special characters, like Æ, Ø and Å.

These characters went missing when my file was being served. Turns out it was just bad encoding. Setting the encoding to UTF8 solved the problem. So check that!

MSMQ - Bare minimum example

Sometimes you need a project to be split into two programs but still pass data between eachother. A normal way of doing this would be with a webserver, like a WCF service.
There is however a simpler way of achieving this functionality, using a windows preinstalled component called MSMQ.

MSMQ is a message queue system. An application can push messages to a queue and another application can read them out. MSMQ also has the advantage of keeping queue messages even if a client goes offline. The messages can then be retrieved the next time the client comes online.

The code:
This first code snippet initializes the queue:

public static MessageQueue mq;
private void btnInitQueue_Click(object sender, EventArgs e)
{
 // Create queue or connect to an existing queue
 if (MessageQueue.Exists(@".\Private$\MyQueue"))
 {
  mq = new MessageQueue(@".\Private$\MyQueue");
 }
 else
 {
  mq = MessageQueue.Create(@".\Private$\MyQueue");
 }
}

This next snippet adds a string message to the queue:

private void btnSendMessage_Click(object sender, EventArgs e)
{
 // This adds a message to the queue
 System.Messaging.Message mm = new System.Messaging.Message();
 mm.Body = textBox1.Text;
 mq.Send(mm);
}

And this last snippet is used to read out the messages from the queue:

private void btnReadOutMessages_Click(object sender, EventArgs e)
{
 // This retrieves all messages in the queue, processes them and deletes them 
 System.Messaging.Message[] messages = mq.GetAllMessages();
 foreach (System.Messaging.Message m in messages)
 {
  // Need to read the messages with a formatter
  m.Formatter = new XmlMessageFormatter(new String[] { "System.String,mscorlib" });
  richTextBox1.AppendText(m.Body.ToString());
 }
 mq.Purge();
}

Notice we need to apply a formatter when reading data out from the queue.
