Printer Driver customize document sheet

Hello friends;

I am writting a printer driver for customizing the Document & printer
property sheet. I am using Win2K ddk & doing work in the unidrv. I am adding
my specification in the sampe code of oemui given in the \ntddk\src\oemdll\
.

It Build successfully but when i click on the “print preferences…” button
it shoud shows my “Customize MessageBox” & then it show the Default Document
Property sheet (i.e. LayOut , paper Quality).

I want to show only the customize message box not anything default.

My Ques is : How to Hide Default Document Property sheet ?

Can u please tell me the appropriate answer asap.

Regards
Asim
