im having some trouble with my loop code. When the isnumeric code detects it not a number it throws the msgbox error message but moveson to the next array for the user to enter a value via inputbox. Is there a way for the program to send the inputbox asking for the value again before moving to the next array?

I'm trying to loop through a bunch of checkboxes I have created on my aspx page. I would like to get all the values, and parse them to a string to send to another page as post variables. This is what i have so far:
aspx page:
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox0" runat="server" /> Name</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox1" runat="server" /> Training Year</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox2" runat="server" /> Continuity Clinic</div>
etc...
aspx.vb file:
Protected Sub Submit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Submit.Click
Dim targetURL As String
targetURL = "report.aspx?"
' This is the part i can't figure out.
' For Each checkbox on page
'if checkbox is checked
'targetURL &= checkboxid & "=true&"
End Sub
My goal is to build another page that will then check these values using Querystring variable, and build a listview out of them. (a report page, that basically lets the user select checkboxes of the columns they want to see on the report).
I am working on a code that should capture the color of a pixel in a bitmap and then check if the 8 surrounding pixels have the same color. If the checked surrounding pixel HAS NOT the same color it will be ignored, otherwise if it HAS the same color, it should check for its own 8 surrounding pixels and so on.
To do that, I have created an array that starts with a single entry (the x,y coordinates of the initial pixel). So, when a pixel with the same color is found it is pushed to the end of the array. I used a for each loop supposing that VB would keep looping until the end of my array - and since it is growing, the last position of the array would be always pushed until I have not more pixels to be checked.
The problem is that VB is not respecting it, and is considering my array as if it had just 1 entry. Seems that it catch the size of the array when it enters the loop, and regardless the fact I have pushed new items to the array it doesnt keep looping it.
How can I force VB to update the end of array position while looping it? Although I think it wouldnt be necessary, here it goes the code I have so far...

I have an assignment that asks me to:
1. create a button
2. when that button is clicked, an inputBox will appear to ask the user how many words they will enter.
3. then display an inputBox for each word.
For example, when the first inputBox appears, I enter "3" (meaning that I will enter 3 words).Then there should be 3 more inputBox (each inputBox allows me to enter only 1 word)After I enter the third word, there will be no more inputBox.How can we FLAG (stop) the inputBox, or let the inputBox know when to stop showing up?

I'm making a card game and I want to try and design my own card deck.
Dim X As Integer
Dim currentCard As Integer, currentCard2 As Integer
Dim RandomNumbers As New Random()
Dim NumberofCards As Integer
[code]....
I started a basic vb.net class for my fall semester of high school, and although I've learned a lot, my goal since the start of the semester has been to do this. I realize there are simpler way of assigning card values than writing 52 if then statements, but I'm planning on doing other things with the statements. As you can see, my main plan of action is to generate a random number for each card, loop through the array list to make sure the random number representing that card hasn't been assigned before, use the value to select the card, and then add the randomly selected number to the array list so it won't be used again (non-repeating random numbers).
1) I'm trying to represent all the numbers with Numberlist.Item(X) and that doesn't work because either a) x represents any one number or b) x always represents only 0, which means it only checks the first number.
2) I think I've read something about using this method for generating random numbers in a loop, that it doesn't work for some reason.

I am trying to create a multi dimension array that will search each row of the array and total up the number of 0's 1's, 2's, and 3's. I believe that I need to create some sort of looping structure that will search through each row of the array.I have created a listbox that will allow the user to pick which row of the array the program will search.This is what I have created so far, but I am only just learning and I am having trouble wrapping my head around how arrays work. So I'm not sure if I am on the right path or not.

In VB6 I could set up code to loop through say 10 option buttons to check their values. The code would be something likie this:[code]But in VB .NET it seems that if I use the Controls command as above I cannot use/check the Checked property as Control does not take that as a property of Control. It seems also that I may have to use the Find property of Control as in "Controls.Find" etc.How can I do this in VB .NET? I have a very control intensive application and I must be able to easily loop through controls and check their values without writing out 10 x the code required.
View 8 RepliesIs there a way of merging (importing or whatver is the correct terminology is) the data from an Array in to a DataTable woithout looping.

Quick question on the InputBox. I am just learning this, what is the code to "read" commands that are placed from the Inputbox? I can do this in the command line: System.Console.Writeline(), System.console.Readline()
I just would like to know how read the line from the inputbox. Also when I debug my script do I -always- need to have the command prompt in the background?

I'm making a quiz and I've got a set of questions and answers being loading into two different arrays, the idea is to answer a question with a choice of 4 buttons, so on a button click the answers checks to see if it is correct and moves along to the next question (while doing this the questions and answers change)However, my problem is that i've set up an audio player as the questions are for example "what is the sound?" and there is a preview button which uses the audio player to play the sound for the user.
Now everything moves with the array however, the sound still remains the same on every question after the quesiotn has been answered. So my set of answers move (when debugging, the sound array does move but the player doesn't seem to want to) with the array and i need the player to change to the specific array position which it is in as well.
Audio Player:
Dim answer = CorAnsList(qNum).sound
Dim answerPrev As String = My.Computer.FileSystem.CurrentDirectory & "sounds" & answer & ".wav"

I know you can do it this way:
inputbox("Please answer a question", " ", "")
This way you put a space in the Title property.
But is there another way to do this without putting a space in the Title property?
Maybe there is an inputbox without a title in vb.net?
