I'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")
Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click

What I'm trying to do is: Set numbers (0-51, a deck of cards) in an array like card(0) = 23 (Which would represent, say, the Jack of Clubs). Then card(1) = 35. Now I have two arrays.
The first array is what I have mentioned above.
The second array is holding a Boolean value. So what I do is make a loop going through the card() array from 0-51. In this loop it generates a random number between 0 and 51. Then I check the second array (iCardUsed()) to see if it holds the random number.
So iRndNum = 13 (Say 13 was the random number)
loops through the second array checking if the there is a value of 13. If there isn't then I want it to set card(whatever it was on, say 12) = 13. then make iCardUsed(13) = true saying card 13 was true. I'm not too sure what to do if it was true, not false.
Alright, now that I explained what I was trying to accomplish, I'll post some code and the project.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim iCard(0 To 51) As Integer
Dim iCardUsed(0 To 51) As Boolean
Dim iValue As Integer

Any hints on how to place these monthly sales numbers in an array so they show up in 3 separate text boxes (one for domestic sales, one for international sales and one for total sales.

I have a byte array with 512 Elements and need to get and set a single bit of a byte in this array.The operation must not change any other bits, only the specified one.So if I have a byte like &B00110011 and would like to change the third bit to 1 it should be &B00110111.
Like this:Dim myarray(511) as byte myarray(3).2 = 1 ---> This would change the third bit (start counting at 0) of the third byte to 1 I know it should be easily possible using bit-masking but I don't have the time to try for days to get it working.

View 1 RepliesI have a VB2005 project that displays 16 pictureboxes in a 4x4 grid which display CD album covers. In VB6 I could set up a control array i.e. picCD(0) to picCD(15), which made drawing the CD covers a snap. How do I accomplish this in VB2005?
It seems extremely cumbersome to have code like: If Len(path(0)) < 1 Then
If Not IsNothing(PictureBox1.Image) Then
PictureBox1.Image.Dispose()

I am working with binary files that have 500 rows and 500 columns (width x height).

View 15 RepliesI have a button which reads a comma separated value file and loads it into a richtextbox. Each line contains comma separated chars.
Once the file is loaded in the richtextbox, i want to be able to select specific values from each line and store them into an array.
For example:
Line1: a,b,c,d,e
I want to be able to place only the values "b" and "c" into an array.
I was thinking something like creating a menu for the richtextbox which will be triggered on right click, then highlight the values I want, press right click and select 'place these values in an array'.
it doesn't have to be the way i proposed it, but it definitely must use a richtextbox.
I am trying to write an array of integers from my VB OPC client but cannot do so.
I am setting my array to the ItemValueResults, then i set the ItemValueResults to a variantwrapper. I can write individual elements from the array but not the entire array.
Maybe to be able to provide a simple example of how its done correctly. I think the issue could be in defining the OPC item as an array.
