I have a newbie question that I hope someone can answer.
VB Studio 2005
I have a form with a button and a listbox. When the button is pressed
the following routine is run:
Public Class Form1
Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
Dim i As Integer
Dim wrap As String
wrap = Chr(13) & Chr(10)
For i = 1 To 10
TextBox1.Text = TextBox1.Text & "Loop " & i & wrap
System.Threadin g.Thread.Sleep( 1000)
Next i
End Sub
End Class
All this does is populate the listbox with loop1,loop2, etc with a crlf
at the end of each loopx.
While this is running I can see that the listbox is getting bigger
because the elevator bar is created and successively gets smaller as
more loops are run. However the words ("loopx") do not appear in the
listbox until the entire 10 iterations of the loop are complete.
Can anyone tell me why this happens? Is there a cure? Can I make it so
that each "loopx" line appears successively once per second in the box?
Thank you.

Listbox, or textbox?
Protected Sub Button3_Click(B yVal sender As Object, ByVal e As
System.EventArg s) Handles Button3.Click
Dim i As Integer
For i = 0 To 10
ListBox1.Items. Add("text " + CStr(i))
Next i
End Sub

Henry,
Thanks for the response but it's a textbox so items.add won't work.
The output is produced, but only after the procedure has completed. I'd
like it to refresh while looping through the procedure.

Try addingt TextBox1.Refres h to the loop
Your code should be:
TextBox1.Text = TextBox1.Text & "Loop " & i & wrap
Me.Refresh()
System.Threadin g.Thread.Sleep( 1000)

New to Python... trying to figure out how to count the objects in a list
and then map the count to the objects or convert the list to a dict... I
think the latter would be better as I need a number associated with each
entry. Any pointers?
Also, does this bit of code look to be truely random?

winner.append(random.sample(xrange(100000), 1))

number = random.sample(range(count), 1)
This makes 'number' into a one entry list (I don't know why as 'count'
is an integer). Is there an easy way to convert 'number' back to an int?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
