display.

2.Student must display a message box that it is the

version 1(or whatever, he choose), on the screen and

he must display some data on this message box on

the screen regarding the application developed.

3.Student should display an output with variable font

colors and background colors.

4.Student should use all predefined window controls

like Buttons etc.(that are in his course) in his code,


3/22

while working on these controls he can display the

information in client area or wherever he choose.

5.Student should comment the code regarding every

new block of code.

6. Student can design his own icon or any other

resource (if he wants, it is not compulsory).

Student should submit the code, resource file and the

executable file to the faculty
