A question about "KeyDown"

I am using Visual Studio and I am w开发者_运维百科riting Visual Basic

How do I write "If button is pressed for one second" ?

This is going to require a timer.

• Set a timer to elapse after 1 second and enable it in keydown.
• On keyup disable the timer
• In the timer event put the code you want to happen after one second of keydown (but disable the timer first so it doesn't fire twice).

Note: you'll need to consider what you want to do in the case of multiple keydowns/presses as this makes this scenario harder.
