I want to use a Button event and Keydown event in my
windows program. But the Keydowm event dosen't work.
If I delete Button and it's event,the keydown event
works.It seems the button prevent the keydown event
happening.I wonder there are some notes I should take
care when I add both button event and Keydown event.
Thanks!! I am longing for the help!

Can you show the code where you seem to be having a problem. It seems to work just fine for me. From what I am getting you want a button to take on a mouse event and keyboard event. Just implement one of the events and you can use the other event to call the one you implemented. Let me know where you seem to be having a problem.

So you can do a mouse down event and a key down event and it calls either some method or each other depending on where you implement the functionality.

Huh O i C

Program or Be Programmed!!!

Make sure the designer did not delete any of the automatically entered Event Handlers. There was bug in VS a while back that did that.

How do u add ur Event to control?! Can u post it?! & as coderforrent said make sure there is event released there maybe with ur designer.

Most probably your problem is that you have implmented the keydown event for your form and click event for your button. When you run your program with button control on the form, the focus by default is on button, now when you press any key it will not trigger any action as you have not implimented any key events for the button. Removing the button from the form however, puts the focus back on the form and now the key events work because you have keydown evetn catchers implimented for your form.

One way to solve this problem is to override ProcessCmdKey function. This function has higher priority as far as keydown intercetpion is concerned. You can catch your key events regardless of what control is in focus.

I think the answer is probably a bit easier than Ankur suggests. Remove the event code that you have and try the steps again from the top.

1. Click the form in the designer
2. Double-Click the event that you want to add.
3. Add the desired calls.

Usually this works for me. I generally screw up by accidentally clicking the wrong control or something along the way.
