When you call DoDefault(), you need to pass the same parameters as the current method received:

DoDefault(nKeyCode,nShiftAltCtrl)

>This seems simple enough. I want to use the KeyPress event in a text box to remap keys as they are typed. Below is a bit of sample code. Of course, it doesn't work...if it did, I wouldn't be issuing this plaintive plea for help. The example below is trying to map a lower case 'a' into a lower case 'b' and a lower case 'd' into a lower case 'e'. What it actually does is do nothing when 'a' or 'd' are pressed and behaves normally otherwise. How do I do this correctly?
