David,
You responded:
>Using DoDefault() and/or an explicit TextBox::KeyPress() call without a NODEFAULT will cause the doubled characters. If you are losing the function of some keys it can only be due to a NODEFAULT issued when it shouldn't be. You also need to make sure you are properly calling the other inherited code from the ParentClass.

Here is my real life example. I have a container which contains a textbox. This textbox is derived directly from the VFP5 class.

The Keypress function contains the following:

LPARAMETERS pKey, pSCA

NODEFAULT && to avoid double keystrokes

DO CASE
CASE pkey = 5 AND pSCA = 0 && down arrow
&& do some stuff - this works correctly
CASE pkey = 24 AND pSCA = 0 && up arrow
&& do some stuff - this also works correctly
OTHERWISE
dodefault(pkey, pSCA) && this does not handle the TAB :-(
ENDCASE


What is wrong with this? Why do TABs and Shift-TABs no longer move the focus to the next and previous controls respectively?

This is a different class from the one that originally gave me this problem.

Thanks in advance.
