The OnKeyPress event doesn't fire if the Key is 'delete' (it fires for
backspace).

How are you supposed to validate text entry as they type if keys that
can change the contents don't fire the event?

Is there a way to either disable delete or force it to fire the KeyPress
event?

Thanks

Russell

Check the 'KeyDown' event.

The text should be validated in the control's 'Validating' event.

I've found that now. Thanks

I'll have a look at it, but at the moment I have a simple wrapper class
that can wrap both Borland's VCL controls and .Net classes to give me a
common, standard C++ interface to UI elements, and the VCL doesn't have
a validating method so I've already got code that worked with OnKeyPress
(just never realised that OnKeyPress didn't fire with delete but I
understand now why not).

I code simulate Validating in VCL but its all working for now.

Thanks

Russell
