This evening, instead of hanging out at the Microsoft Dev Days Geek Night, I drove home, put the kids to bed, and sat down to figure out how to update my Twitter status from the Windows Powershell. This was inspired by the bash one-liner using curl that I learned about from Peteris Krumins’ blog (recommended). Well, it turns out not to be a one-liner in powershell, but FWIW - here's how!

function tweet([string] $status) {
   #http://blogs.msdn.com/shitals/archive/2008/12/27/9254245.aspx
  [System.Net.ServicePointManager]::Expect100Continue = $false
  try {
    $wc = new-object System.Net.WebClient
    $wc.BaseAddress = "http://twitter.com"
    $wc.Credentials = new-object System.Net.NetworkCredential
    $wc.Credentials.UserName = "Your account name"
    $wc.Credentials.Password = "password"
    $stream = $wc.OpenWrite("statuses/update.xml")
    $writer = new-object System.IO.StreamWriter -ArgumentList $stream
    $writer.Write("status=" + $status) 
  }
  finally {
    $writer.Dispose()
    $stream.Dispose()
    $wc.Dispose()
  }
}
