Application Program Interface (API) Summary

AddToUserDict	Add a word to a user dictionary file.
CheckText	Checks the spelling of words in a string: a phrase, sentence, paragraph, or an entire document. CheckText returns to your application when it finds the next misspelled word in the string or when it reaches the end of the string. 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.
GetUserDict	Obtain the set of words in a user dictionary file.
InsertText	Insert some text (e.g., a word) into a string at a given position. InsertText is typically used when replacing a misspelled word with a correction.
NextTextWord	Advance to the word following the current word. NextTextWord is used to skip over a word reported as misspelled without correcting it.
Suggest	Locates suggested alternative spellings for a misspelled word. The set of suggestions is returned in order of decreasing probability of correctness, so the first word is the best choice. Suggestions can be located using typographical (looks like) or phonetic (sounds like) matching, or both.
WordCount	Return a count of the number of words in a string.

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 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>, <, 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.
