 Module Name:

    Chollian2000Plus.cpp

 Abstract:

    The app has a binary logon.ocx which uses sub-classed editbox as password 
    editbox. It does not hook all messages (whistler seems has more message 
    than win2k's), so when the mouse drags through it, the password typed will 
    be shown as plain text, the fix is to apply ES_PASSWORD to this specific 
    EditBox.

 Notes: 
  
    This is an app specific shim.
