The application uses ADO.NET to invoke sprocs for nearly every database operation. Some of these sprocs also contain a fair amount of domain logic. The data access logic for each domain entity resides in the domain class itself. ie, there is no decoupling between domain logic and data access logic. I'm looking to accomplish the following:

View 3 RepliesI have a combo box, I have entered in 6 different world wide destinations for example:London, Paris, New York etc The program is for booking plane tickets, at the moment the user has to input the cost of the journey manually into a textbox and then depending on the number of tickets requested will calculate the cost.
What I would like to do is to assign a unique numeric value (the specific cost of the flight for one ticket) to each of the items in the combo box list so that when a user selects a destination the default cost of the ticket is already known and does not require the input of the user.Private Sub cmbDestination_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbDestination.SelectedIndexChanged End Sub The idea is that which ever destination is selected, for example: Paris - �155 would then set the variable 'ticketPrice' to 155 and allow me to change the calculations of the program to not require user input.

Right now i have the following code. it is 4 radio buttons that if selected will display the price of a ticket.
There is a button called "repeat offender" that should take the price and double it. so me, being new to visual basic, were thinking of trying an if statement such as If it is selected decTicketTotal * 2
But this did not work. any help would be appreciated.. just trying to get the repeat offender selection working so when it calculates the price will double.

I have 3 tables:Sales data - SaleID, Date, StoreID, CategoryID, Cost, Retail
Store names - StoreID, Name
Category names - CategoryID, Name
I have a dgv bound to my sales table, and 2 comboboxes, one each bound to the remaining tables, with display member set to the name, and value member to the ID.
An ID of -1 represents "All Stores" or "All Categories"
An ID > -1 represents a specific location or category
So, can I use some sort of If,Then,Else logic to do something like this:
SELECT (*) FROM Sales
WHERE (IF @StoreID > -1 THEN StoreID = @StoreID ELSE True)
AND (IF @CategoryID > -1 THEN CategoryID = @CategoryID ELSE True)
AND Date BETWEEN @Date1 AND @Date2
I've found some different examples of If/Then/Else and Select Case type logic for SQL using google, but they don't seem to fit my situation, and I'm not sure how to apply that to what I'm attempting here.

I read from a table that gets x number of records. From the results, I create dynamic check boxes. It's OK if x is greater than the previous refresh but when it's less than, I can still see the old objects.
If I completely close the form and re-open it, it works fine and that is exactly what I'm trying to emulate. However, I'm failing miserably. Here's a broken down version[code]...
