How can the data from Vb.Net pass to the Text Box in Microsoft Word?

sure, now i have the problem in passing some data to Ms Word.

my program is to write a offer letter which require some data inside such as name, email address,
handphone number and so on.

i have a sample format letter was write just only without the data of name, email address, handphone number.

Via the VB.Net i can pass the data to the letter such as fill in the form.not need manually insert to the letter.
