AddToUserDict
Add a word to a user dictionary file.

CheckAllText

CheckAllText checks the entire string, and returns a report containing information about each misspelled word found. CheckAllText also reports incorrectly capitalized words and words requiring automatic or conditional correction.

CheckText also reports incorrectly capitalized words and words requiring automatic or conditional correction.

DelFromUserDict
Remove a word from a user dictionary file.

DelText
Remove some text (e.g., a word) from a string at a given position. DelText is typically used when replacing a misspelled word with a correction.

GetTextWord
Obtain the word in a string at a given position.

Suggestions can be located using typographical (looks like) or phonetic (sounds like) matching, or both.

WordCount

Options

The following options are supported by the Spellex Spelling Server. Options can be set as defaults that apply to all spell-check requests or can be set for individual requests

  • Ignore words that start with a capital letter — useful for checking text containing many proper names that may not be in the dictionary.

  • Ignore words containing a mixture of upper- and lower-case letters, such as PrintScreen, yearToDate, or ActiveX — useful for checking text containing variable names, computer terms, etc.

  • Ignore words containing embedded digits, such as Win98.

  • Ignore words containing only capital letters, such as USA or IIS.

  • Ignore words that appear to be Internet domain names, such as spellex.com.

  • Ignore HTML markups appearing in the text such as <HEAD>, </B>, &lt;, etc.

  • Report the same occurrence of a word appearing twice in a row, such as the the.

  • Turn case sensitivity on or off.

  • When locating suggestions, check whether the word may have been misspelled by incorrectly joining two words — for example, suggest the dog for thedog.

  • Use typographical (looks like) or phonetic (sounds like) matching when locating suggestions. Phonetic matching uses English pronunciation rules only, while typographical matching works for all languages.
