and rapid application development (RAD) concept. Like the spin button, it is equipped

with two buttons. Each button has a small picture (a bitmap) that displays an arrow.

The application we are about to develop is for a CD publishing small business. This

company manufactures compact discs for self-promoting musicians and small business

that want to sell their own CDs. When taking an order of a new CD, the company

charges:

?? $20/CD if the customer is ordering less than 20 units

?? $15/CD if the customer is ordering up to 50 units

?? $12/CD if the customer is ordering up to 100 units

?? $8/CD if the customer is ordering up to 500 units

?? $5/CD for any order over 500 units

   m_EditQuantity


7. Add a CString variable for the IDC_ UNITPRICE control and name it m_UnitPrice


8. Add a CString variable for the IDC_ TOTALPRICE control and name it
   m_TotalPrice

CCDPublisherDlg::CCDPublisherDlg(CWnd* pParent /*=NULL*/)

: CDialog(CCDPublisherDlg::IDD, pParent)
