Ok,
Let's guess what is wrong!
Maybe it won't compile because
objWord = New WordApplication1.Form1()
isn't the way that a word automation object is created.
Even if you fixed that I think there will be many other errors as you have not dimensioned the variables correctly.
Use
Dim objWord as Word.Application
not
Dim objWord as Object
Probably the best thing you can do is take at look at this code sample
Spell Check from VB.Net[
^] which does exactly what you want. You'll notice that there is no need to use the clipboard to transfer data from a textbox into the word document.
