I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .

Lets say I declare a public array for a structure, and initially I give it 99 indexes (well 100 with base 0), how would I get the first empty index? I thought of doing it like this but a structure array cannot be nothing:
Dim index As Integer Dim RecipeItem As New RecipeItem RecipeItem.name = InventoryList.SelectedIndex RecipeItem.amount = AddItemAmount.Value For index = 0 To _recipe_item.GetUpperBound(0)

Under VB2 I could create a form with many charts (One form had 12 graphs). You could define the chart once and cut and paste it the required number of times on the form. Each chart had an index and the code used the index to create and update the desired chart with the appropriate x,y data. Is it possible to do this in VB2010?

I am working on a project for software engineering where we are trying to create a warehouse inventory system. I have created an inventory page where I can add/delete/search for an item as well as access invoices and reorder items... i am struggling on the delete item part. I have my design set up where there are four different lists on my page. One for name, one for serial number, one for RFID number and one for amount in stock. I want to be able to select an item by name and its information in serial number, rfid, and amount also select and have no idea how to go about this..I wanted to use four different lists because I need to be able to delete an item from the list and it remove just one from that stock and not the entire item unless there is only one of that item left in stock.
for my inventory page

i have an array of 30 strings , the names of the commands send to the serial port, the serial port adresses 16 devices. each device has its own set of commands.
of course i could make subarrays for each device, but for the saving of memory it would be better to use a integer index to name the commands, so like command 0 to 30.
dim command(29) as array of strings. dim device(7) as array of devices.
