red line under miss-spelled word(like MS-WOD)

Dear All,

I have to develop a word processing module of a s/w. I am planning to use rtf control in it. It will support formatting options.

PROBLEMS:

1. The clients require that When they type text, then if a word is mis-spelled it should get curly-red-lined automatically( As in MS-WORD). I don't know how to implement it( MS office is installed on the client's pc; i know i can call some dll/api to use this fuctionality of MS-word's but don't know how). plz guide.( what i want now is HOW TO UNDER LINE MISS SPELLED WORDS AS THE USER TYPES IT)

2. user should have the facility to insert an existing file in the rtf control. for example from the form user browses a file(let notepad file) and opens it. Now an icon of the notepad should get inserted in rtf. now if user clicks that icon, that iserted file should get opened. Plz guide how to implement this functionality.
