BalloonTipTitle and BalloonTipText max length

NotifyIcon.BalloonTipText max length = 255 characters
NotifyIcon.BalloonTipTitle max length = 63 characters

Source: Trial and error.

Good luck finding these specs anywhere. Seems to be one of the lesser documented items in the Windows API (or it requires a very specific search term). Funnier still is you won’t get any compiler errors in Visual Studio 2005/2008 if your string is longer than the above mentioned lengths – you’ll just have to wait for your balloon tip to get cut off when it’s displayed.

asp.net: vs_targetSchema meta tag (and others) no longer required

Recently I was migrating legacy asp.net pages (v1.1) to 2.0 and noticed the following code snippet in every header:

  <meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1" />
  <meta name="CODE_LANGUAGE" content="C#" />
  <meta name="vs_defaultClientScript" content="JavaScript" />
  <meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5" />

Apparently the tags had been used in the past for design-time html support/validation. They’re no longer required if using Visual Studio 2005 or higher.
