This is my first step to learn MFC,when i do the exercise,so many difficult problems puzzled me.Even more,the book doesn't have any keys.I am quite at sea now,so i wish a good sort could help me.Sincerely thanks!
1. Your company manages inventory with a software package that was
developed in-house by using Visual C++ and MFC. Changes to government
regulations have led your company's Information Technology department
to develop a new version of the package. This new version will replace
the older version entirely. The new version will generate the same
reports that the older version generated, in addition to new reports
required by the changed regulations.
To ensure that the new version meets its specifications, your team will
perform testing on the package prior to full deployment. Among the
specifications is the requirement that the new version perform
identically to the older version on reports that both versions support.
You want to test the package to verity correct support for these
reports Which kind of testing should you perform?
A. unit testing
B. integration testing
C. customer acceptance testing
D. regression testing
E. beta testing
2. Your company develops a new Windows-based application for a
customer. The customer has been unwilling to send any employees to your
office during the development cycle because of the distance between
your office and the customer's office.
The application has passed its unit and integration testing phases at
your office. You are ready to install the application and begin the
user acceptance phase of testing at the customers office.
What should take place at the customer location to ensure effective
user acceptance testing?
A. user training

? an edit control for entry of the person's e-mail address
? a group of two radio buttons to indicate whether me person prefers
to be contacted by telephone or by e-mail
When the E-mail preferred radio button is selected, your application
should enable the e-mail edit control and disable the telephone number
edit control. Conversely, when the Telephone preferred radio button is
selected, your application should disable the e-mail edit control and
enable the telephone edit control. How should you accomplish these
goals?
A. Call the CEdit::SetModify function with an argument of FALSE to
disable an edit control.
