Ever find yourself hoarding little pieces of code that are always coming in handy? Snippet Manager is a little utility written in C# that collects all your code snippets into one convenient location, allowing you to save them into XML, or copy them into any code editor using the clipboard.

Introduction

I like the snippet manager written by Tim Sneath, but when I use it and have a lot of code snippets, I only can see the title of my snippet and cannot remember, what is its content. So I added the functionality of a tooltip which provides me the contents. The tooltip is limited to 24 lines.

Using the Code

I only added a simple method to SnippetUI.cs, which receives a control and a message text as arguments and attaches a tooltip to the control.

/// Attaches a tooltip to a control
private void CreateToolTipForControl(Control ctl, String msg)
{
 // split by carriage return
 String[] lines = msg.Split(new char[] {'\u000D'});

 // StringBuilder is faster
 StringBuilder sb = new StringBuilder();

 // maximum lines
 int lineCount = lines.Length;
 if (lineCount > 24)
 {
  // only show 24 lines
  lineCount = 24;
 }

 for (int i = 0; i < lineCount; i++)
 {
  // tab-character
  char tab = '\u0009';

  // line-feed-character
  char lf = '\u000A';

  // must replace tabs with whitespace to show properly
  String line = lines[i].Replace(tab.ToString(), "    ");

  // must replace line-feeds to show properly
  line = line.Replace(lf.ToString(), "");

  // append String
  sb.Append(line + "\n");
 }

 // append 3 dots if text exceeds more than 24 lines
 if (lines.Length > lineCount)
 {
  sb.Append("...");
 }

 // attach tooltip to control
 toolTip1.SetToolTip(ctl, sb.ToString());
}

This method is called everytime the toolwindow synchronizes its contents.
