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.
