I have several checkboxes in a groupbox on a vb 2008 express userform. I would like to check the checked status of each when clicking a command button and then write the checkboxes caption to be used in an email or print out. I've tried several methods and always end up with the same error "Invalid Cast Exception". I have read the help on msdn and still do not understand how to make it work. Here is the code I've been trying
Dim chk As CheckBox
Dim sb As New System.Text.StringBuilder
Dim names As String
For Each chk In gbInterior.Controls
[code]....
I have also tried the code below but cannot figure out how to check the status and print the checkbox caption.
Dim ctl As Control
For Each ctl In gbInterior.Controls
If TypeOf ctl Is CheckBox Then

View 5 RepliesI made a program that generates random numbers and places the numbers in two separate labels.How can I make the number in the first label greater than the number in the second label.Here is my code for generating random numbers:
Dim nRandom As Integer
Dim nRandom1 As Integer
Dim randomgenerator As New Random[code]....
I want to make the first number greater than the second because the numbers should be subtracted .
I have to create a list of 25 randomly generated 0s and 1s in a list box?Next I have to count the number of 0s and put in one label box and number of 1s in another label box.
txtTotalMem.Text = lstInfo.Items.Count
but it counts the overall amount. I need just one type. I tried using the lstRandom.SelectedItem method but you never select the item as it is just random generated numbers. The (relevant) code so far is
'Load the listbox with 25 random numbers between 0 and 1
Dim intCounter As Integer
For intCounter = 0 To 24
lstRandom.Items.Add(RandomGenerator.Next(0, 2))
Next intCounter
'Calculate the number of 0's and 1's stored in the listbox and place in appropriate labels
I know I am missing the obvious. I would like a label to show how many cycles in loop are left.

I'd like to create a loop that dupliates a label I've made and put it all over the screen. Example of what it would look like.
For i = 0 to 52
originalLabel.duplicate ("duplicatedLabel" & i)
next i
So later I could go through all of them...
For i = 0 to 52
//... some logic to determine color... then assign it somehow
duplicatedLabel & i.backColor = Color.red
next i

I can do that in Flash/Actionscript but dunno how to do it in VB and I can't find it anywhere.

I'm trying to change a text that a label displays during each iteration of a Do While loop in Visual Basic. One label (which displays an integer) works fine, however the other stays blank until the loop finishes and displays the final result.

I have an array of labels on my form which are all named "lblLabel1" thru "lblLabel9", but I want to be able to take a users numeric input (lets say 3), and display the 3 on lblLabel1, then I need it to increment by one all the way to lblLabel9. How can I do this? I was thinking a loop so this is what I came up with, but it didn't work:
For b As Integer = 0 To 8
lblLabel(b).Text = String.Concat(intSomething, "+", intAnother, "=")
Next
'Where b = the label number (I know it's zero based, I would change it later)
Private Sub uiSCORE_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles uiSCORE.Click
'Displays Correct or Wrong in Labels
If ui1Textbox.Text.ToUpper = "FOOD" Then[code]....
I finally finished all my labels and textbox codes for this button.But now I have to code it so that I will be able to click the button and it will calculate all the wrong and correct answers in the labels and then finally place the percentage score in the uiScorePercentagelabel. What I dont understand is how to calculate all the different labels as one and then show the percentage right in the appropriate label.
I have been using vb6 for a while, I am following a tutorial by MS to develop a basic application and a simple task cannot be completed for whatever reasons! The tutorial asks to drag the label object from the toolbox and drop in the tab control container. Then, go to the label size property and adjust the size to some different dimansion. Basic stuff, right? It won't let me do it! After I enter the new dimensions (which by the way are not large or very small), the label size (both width and height) resets back to its original dimensions! I have the vb.net sp1 installed.
