View 1 RepliesAccessing And Creating Variables Inside A For Loop?
Oct 15, 2011I have some variables that are distinct by numbers, like in1, in2...If I have for loop, how would I access those variables, using the counter, and attaching it to the variable?I believe in JAVA, you could just use in+ct... where ct is the counter to access the variable.also how could you make a new variable in the for loop?Initially I had variables declare outside of the for loop. The problem was how to access those variables using the for loop.
var_nm1 = in1.Text
var_nm2 = in2.Text
var_nm3 = in3.Text
Dim nmList(2) As Integer

This is object oriented programming, and I made the textboxes in1, in2, and in3 using the GUI editor. that was so easy.

View 3 RepliesAccessing Public Properties Of An Object Contained In A Listbox?
May 8, 2011I have to make a VB project for one of my college Co-Sci classes. However, I am having issues doing what I think is logically possible. Part of our project entails creating a user defined class, then create a form that then instantiates an instance of the object type. After that we are to list the item in a listbox. That is all well and good and works fine.
What I need help with is looping through each object in the listbox, getting some data from the object, then moving to the next.
I have been trying something similar to c++. For example, an object contained in a c++ array can be accessed like this:
array[index].someObjectMethod().
How would someone do something similar to that for objects contained in a VB listbox? I imagine it starts something like this:
myListBox.Items(index).

C# - Loop Through A Multi-column Listbox In WPF?
Oct 5, 2011I have a listbox with two columns. Each listbox item contains a horizontal stacked panel which in turn contains textblocks.
The listbox is empty, with each listbox item being added by the end-user through a couple of textboxes placed elsewhere. The first column accepts strings, and the second column accepts only percentages.
(I have attached a relevant portion of the event sub where a user is adding new rows.)
Private Sub btnAddItem_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles btnAddSplit.Click
'...
Dim ListBoxItemName As New TextBlock
[Code]....
I would like to be able to check every time the above event is fired that the column of percentages does not exceed 100%. I have a couple of labels below the listbox itself where I would like to show the running total and the remainder.
My questions are:
1) How can I loop through the second column of percentages to show the running total and remainder?
2) Is there something more suitable than a ListBox that could make this easier?

Refresh ListBox Control During Loop
Dec 6, 2011Using ASP.NET and VB.NET code behind, I have the following code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim I As Integer = 0
For I = 0 To 10
ListBox1.Items.Add(I)
ListBox1.DataBind()
System.Threading.Thread.Sleep(300)
Next
End Sub
The intended output of the code is to update the listbox1 control at each iteration, but what really happens is it updates the listbox1 control after the entire loop finishes..Is there a way to update the listbox1 control as its intended by the code logic?
