VS 2010 Reverse Alphabetize A List?

Mar 11, 2011

I have this coding for alphabetizing a list of the 50 states, but how would I reverse the process?

Private Sub btnAlphabetic_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAlpha.Click
lstOutput.Sorted = True
Dim highestIndex As Integer = lstStates.Items.Count - 1
For i As Integer = 0 To highestIndex
lstOutput.Items.Add(lstStates.Items(i))
Next
End Sub

Can't Get Number From List Box To Display In Reverse In Text Box

Mar 10, 2012

Build a small application that fills a collection (list) with 10 sequential numbers, and then prints the collection(list) in reverse order, skipping every other member, until the entire collection has been displayed. For example, if the collection contained the numbers 1 through 10, they would print as:

10, 8, 6, 4, 2, 9, 7, 5, 3, 1 The print out should be in that order no matter what sequential numbers are in the collection (list). If it were 21 through 30, output would be 30,28,26,24,22,29,27,25,23,21 and so forth.

Note: you must use a collection - do not write down the numbers directly to produce the output. Loops should be employed but the loop control variable should be used as an index or subscript number. Your code should work even if I change the list of sequential numbers to something else. Remember that indexes count from 0 first -- the first item in a collection has index 0, the second item in a collection has index 1, and so forth.

I've got the first part of the problem, getting the numbers in the list box, done with no problem. It's the second part I am struggling with. I cannot get the numbers (I am using 1-10) from the list box to display in reverse order in an adjacent text box.[code]...

Create Reverse PTR For DNS And WMI?

Dec 14, 2010

So far I coded CreateARecord to create the ARecords on my DNS server and it works like a charm, but in the GUI version of DNS it allows you to check a small box that creates a Reverse DNS PTR in the reverse lookup zone, Part of the code below is from VB6 which was code that allows for creating a Reverse PTR in the reverse zone, does anyone have a DOTNET version of that that checks to see if the zone exist just like the one below?

Code:
Private Function CreateARecord(ByVal RecordName As String, ByVal IPAddress As String) As Boolean

.net - Assistance With TCP Reverse Connection?

Jul 3, 2010

I am creating an authentication server for some projects I'm working on. This authentication server works by receiving and transmitting data to users trying to authenticate. The user can send data to the server succesfully but when sending back it requires port forwarding. I read a way that I would not require port forwarding by using reverse connection but I have no idea how to get it working. I found a tutorial and tried to implement but when it tries to connect to read the stream it says the connection is refused.
