New usefull program

I have idia for making new tool for MS Word.

This program would work like auto correct function in MS Word, but with some futures...
Every time when some text is typed in MS Word, program would read it and add it to programs's data baze. So printing text would be much faster if the word would repeat. Youl shouldn't type all word, only some first letters ant press enter.

Any suggestion and ideas.
If you want to join making this program write to [email protected]

You could call it AutoText and put it on the Autocorrect tab of the menu, and have it autocomplete things like dates as well...:D

OK, How to make this control apear in MS Word. I haven't done anythik like this before. What I neeed to declare and shold I select active dll project?
