Key Stroke capture

[Doug]

In a VSTO project I want to be able to capture every keystroke and be given
control in my C# code so I can make a decision on what to do.

Such as somebody hits the space bar I want to insert a "Happy face". Or if
someone selects and hits the delete key, I get to intercept the delete and
decide what to do if anything.

Any help is appreciated.

Doug

The Word object model doesn't provide this. You'd need to work over the
Windows API.

Hi Cindy,

Thanks for the reply.

I am not familiar with the technique using Windows API. Do you have some
links to any examples?

I appreciate the help.

No, I haven't, I'm sorry. The only people I've ever known who've managed to
do this successfully have been programming using C++. And they haven't
shared the details, once they've figured it out...

I've tried a while ago. IIRC, the problem was to not interfere with Word's
handling of the input (which would make say the spell checker fail).
On another forum, Rory suggested:
"My admittedly brief reading on the subject seems to indicate that if you
use the CallNextHookEx function, it will then simply pass the keystroke on
down the line so it will be processed normally after you have registered
it."

Haven't ever gotten it to work, but maybe CallNextHookEx may turn something
up on Google?
