MS Office Forum / Word / Programming / June 2007Key Stroke capture
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.

You'd need to work over the Windows API.

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

And they haven't shared the details, once they've figured it out...

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? Klaus |
