How To Code This Voting And Storing Into An Array Program
Nov 29, 2010note, this is homework. It's not worth much, but i really need to learn how to store things in arrays. my biggest confusion is that i have no idea how to store something in an array, have the program run again andcontinuouslybuild the array andthen display the array in its current state (by like clicking a display poll button) and then still allow it to build more once more data is entered.Here's the whole assignment. I don't really understand how to start it and the problem above is my biggest frustration!ite a Visual Basic application that can be used to determine the best Super Bowl commercial. The choices are as follows: Budweiser, FedEx, E*Trade, and Pepsi. The application should allow for the user to enter a voter's name, gender and select a commercial from a list.
Create a Vote structure that will contain the voter's first name, last name, gender and the selected commercial. Each time a vote is entered, the information should be added to an array of Vote structures.Provide the ability to save your data to a sequential access file. The program should also be able to read an existing file of vote data into an your array of Vote structures. Doing so, should eliminate any data that may have already been in the array.
Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

Code An Array Of Structure?
Mar 26, 2009I am once again struggling with my weekly project. I am assigned to write a program that converts a predetermined english sentence to both french and german. The code is to contain an Array and a structure. Also we have not covered retrieving array data from a TXT file, so we are to hard code in the array data. I coded the structure and the array, I added the array data, but am confused how to access the data. The examples I have found all deal with retrieving data from a TXT file. Can someone give me a nudge in the right direction.[code]....

2 Dimensional Array List - Paste In The Code
Nov 18, 2011i have been working on a simple program but cant get my head around it. It does not show any errors at the moment but when i run it does not do the things i would like it to do. I will paste in the code first and explain it below.

So basically the form has help button to show instructions, quit to quit the program and check to check whether the country from listbox lstCountries matches the correct capital in lstCapitals. The idea of the program is to shuffle the items in two arraylists and then add them to seperate listboxes called lstCountries and lstCapitals. At start i used 1 dimensional array and it worked like a charm for mixing up items in arrays and then adding them to listboxes, but then the problem had to match the correct Country with correct Capital and it only worked if i picked the items on the same index such as 1 and 1(straight line). It all sounds complicated and confusing, P.S alot of code is commented out, because i have tried many ways to make it work.

Button Array - Code Used (extremely Inefficient)
Aug 10, 2011I have a button array that I filled up. Here is the code I used to do that.

For i = 0 To 29

i += 1
Next i
Here is some code that I used (it is extremely inefficient):

Pass String Array To Unmanaged Code In A Dll?
May 10, 2009First of all; I'm completely new to VB.
Pass a string array from Visual Basic Express 2008 to unmanaged code in a Dll.The array is Dimmed as in DIM myArray(11) as String
I'm developing the dll myself using Powerbasic.
The dll expect a 4 bytes pointer to a safearray's handle. As far as I have understood it; the array's string elements must be passed in ANSI format. The code in the dll will then use OLE Api to get the LBound and Ubound of the array and the address of the first element in array.

If x > b(1, 1) And x < b(1, 2) Then a1(i, j + 1) = 30

Detecting Clicks On A Code-created Array Of Picboxs
Feb 28, 2012I'm currently implementing an inventory screen, a simple grid of picture boxes which displays what the player is carrying (read from a simple array of items).
I can create a nice array of picture boxes (allowing me to easily change their .image property to display items) but now I would like to capture a click event on these newly created picboxes, so when one is clicked, the items attributes are collected from the array and displayed below.
For a picbox created in the designer, this is easy, as I just double click the control, and enter my click event in the sub that is created. How would I do this for a code created picbox however?
Here is the code I use to generate my array once the inventory form loads:
Private Sub Inventory_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim x, y As Integer
[Code]....
I have done a few tests, and I know that the names of the boxes are pb00, pb01 etc, but I cant seem to make this work.
