Working with CBitmapButton

What type of application you working with dialog based ya Document view based.

i think you cant overide key bord event in a dialog based applicatio if you have controls in your dialog.

in that case you can try for pretranslate message. get the key down and key up events and process what you want to do with them

LIKE

BOOL CTestDlg :: PreTranslateMessage ( MSG* pMsg ) {

if ( pMsg->message == WM_KEYDOWN ) TRACE ( "\n\n KEY DOWN" );
else if ( pMsg->message == WM_KEYUP ) TRACE ( "\n\n KEY UP" );

return CDialog::PreTranslateMessage(pMsg);
}

you can check the key values also here
