Hello:(
I have an assignment to build the booking and payment part of a Thearte Booking System. I have four classes linked to an MDF database
- well they should be - the two that we have been given will will be and the two that I have done might be!
The first thing that I have to do is test the classes on a test form.
As an example I have put the SheduledEvents class at the bottom of the post (one that I have been given so it should be correct).
So, as I understand it - I have to return a lsit of scheduled events to the test form, say in a list box, from a ScheduledEventSortedList.
I have spent two days trying to return the data row for scheduledEventID on my test form and failed. There is an example of one attempt
of many below, and like all the others, it doesn't work.
namespace TheatreTicketBooking
{
public partial class ScheduledEventsTestForm : Form
{
int ScheduledEventID = 0;
ScheduledEventsTestForm[] TestEvent;
public ScheduledEventsTestForm(int SEID)//SEID for ScheduledEventID
{
InitializeComponent();
lstEventData.Text = " Scheduled Event ID: " + ScheduledEventID;
return drEventList[0];
}
}Could someone please point me in the right direction
All the best John:)
Here is the class that I am testing
