Hi.
okay, will ask specific questions?
1. How do i display the Rental Amount, Discount and Amount Due?
2. How do i display the total due, after the discount?
okay, hope this is more specific.
just wanted you to show what i did, not to evaluate my whole code, but to
show you the code below, so you could get an idea, where i am coming from.
okay, if some one can point me out, where i am going wrong, or point me out
code samples on the net, tried searching on msdn, google and altavista, for
simple examples, but only advanced, complex examples.
cheers Marvin.

Sir,
Could you ask spacific questions sir. We do not wish to evaluate your
entire program for you. That takes away from the learning experience! If
you ask spacific questions, perhaps someone could offer you a spacific
answer and explain why what you did doesn't work and why what they showed
you does. I applaud your learning desire. However, how much are you
learning by sending your entire code and having people to evaluate it.
Thanks!

Hi.
doing this book for a programming subject, and now need some help, not to do
my home work for me, but to give me pointers how to fix the problems and the
calculations.
or maybe point me to some good online examples.
really struggling, and need some help.
and please be gentle with me, tried looking at the msdn, help, and tried
searching on google and altavista for some simple examples, similar to this
case study, but could only find really complext examples.
so, if you could help me out, let me know either on or off list.
cheers Marvin.
ps: will post the project description and my code below.
Video Bonanza
Design and code a project to calculate the amount due
and provide a summary of rentals. All movies rent for
$1.80 and all customers receive a 10 percent dis-
count.
The form should contain input for the member
number and the number of movies rented. Inside a
group box, display the rental amount, the 10 percent
discount, and the amount due. Inside a second group
box, display the number of customers served and the
total rental income (after discount).
Include buttons for Calculate, Clear, and Exit.
The Clear button clears the information for the current
rental but does not clear the summary information. Do
not allow bad input data to cancel the program; in-
stead display a message to the user.
