C# - Form APP. Question about Microsoft Word Contaxt menu for a spell check operation

[avi1000]

Hi
I want to do something with microsoft Word spell check and I wanted to know if it's possible.
I have a TextBox and I want to check the word in the textbox with the help of Word spellcheck.
I have two problems:
I want to be able to right on a word and get the contaxt menu with the suggestions.
according to this article:

Article Link

I only have the dialog with the spell suggestions.

2) After I chekced the word and the dialoge window was opened according to the above link, I clicked on a suggestion to change the word but the word in my textbox didn't changed and a Word doc was opened with the word.
Can I avoid that so only the word in my textbox will be changed?

thanks in advance
