How to detect Page Down/Page Up keys, etc.

[foo]

Hello,

I can trap alphanumeric keys wih this code but the event doesn't even fire
when a page down, page up, home, end is pressed. I've overloaded the
OnKeyPress event for the form. The event will fire on alphanumeric keys,
punctuation, etc. Why won't the event fire on Page Up/Page Down keys?
Protected Overrides Sub OnKeyPress(ByVal e As
System.Windows.Forms.KeyPressEventArgs)

Select Case Val(e.KeyChar())

Case Keys.PageDown ' Page Down

....

end function



Thanks,

These keys don't create chars. Use OnKeyDown instead.

For the other keys, you need to override the OnKeyDown method.
