    Gets or sets a custom spell-checking parser.
    Syntax
    'Declaration
     
    Public Property CustomParser As ISpellParser
    public ISpellParser CustomParser {get; set;}
    Remarks

    This property allows you to specify a custom parser for breaking up text into words to be spell-checked.

    For example, you may want to use a custom parser when checking source code files. This way you can spell-check the comments in the code and skip the actual code.

    Example
    The class below implements a custom parser that breaks words that contain underscores or mixed case into separate words. For example, this parser would treat "Customer_Code" or "CustomerCode" as two separate words.
    public class Parser : C1.Win.C1SpellChecker.ISpellParser
    {
      CharRange ISpellParser.GetNextWord(string text, int start, IgnoreOptions ignore, string previousWord)
      {
        // start with default implementation
        CharRange range = CharRange.GetNextWord(text, start, ignore, previousWord);
        
        // additional logic to handle underscores and mixed-case
        if (range != null)
        {
          // get original word
          string word = range.Text;
          
          // split word at underscores
          int index = word.IndexOf('_');
          if (index > -1)
          {
            word = word.Substring(0, index);
            range = new CharRange(word, range.Start, word == previousWord);
          }
          
          // split MixedCasedWords
          for (int i = 1; i < word.Length; i++)
          {
            if (char.IsUpper(word[i]) && char.IsLower(word[i - 1]))
            {
              word = word.Substring(0, i);
              range = new CharRange(word, range.Start, word == previousWord);
            }
          }
        }
        
        // done
        return range;
      }
      string ISpellParser.FilterWord(string word)
      {
        return word;
      }
    }
