What Is Wrong With Reverse For Loop
Apr 13, 2011
I am trying to print out a triangle of stars with the longest side on the top. I have tried adding removing step, changing value of step, changing order of 5 to 1, 1 to 5 but I can't get it to reverse. I thought that is what step does? [code]

I am fairly new to VB and I am struggling with not using the Reverse string.I need to take a persons name from a text box and print the name backwards in a label using lop and the MID function.I have this, but it doesn't use the MID Function, how would I change it.
Private Sub convertButton_Click(sender As System.Object, e As System.EventArgs) Handles convertButton.Click, ClearToolStripMenuItem.Click

I'm in a pickle... either that or it's getting too late in the day. How do I loop through an array in reverse without using FOR?I have an array of string values, I need to loop through these values until I find the first instance of a value then stop. I have considered a sort on the array but each query would need me to sort it accordingly (the data in the array has many instances of the strings within strings I am looking for, e.g. there could be several 'to' but I need the first, there could be several 'from' but i need the last)When I find the instance of the string, I then need to grab specific data from that string.

I know how to loop through a GridView and extract each row using the for each loop as below, but I was looking for a easy way to loop through the datagrid and say extract the last 20 rows? Is it possible to go through in reverse order in vb.net?
For Each row As GridViewRow In InventHistoryGridView.Rows

Im writing a program and its pulling data from a .MDB to put in a .DAT file.
Here is my while loop:
vb
database_connection()
sql = "SELECT * FROM tlalist"
[Code].....
In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.
Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

I have the array dimensioned as public to the form. I populate the array on Form1_Load.When I click the button btnReversingAnArray the first time all are sorted in reverse except for Wendy and it is the last item shown. ie..(The book I am even shows an image of the list Box and their example also shows Wendy as the last item)
Richard
Michelle
Jay
Harriet
Wendy
Then I do nothing else except I click the button btnReversingAnArray again and then it displays correctly.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.
Option Explicit On
Option Strict On

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
ConnectToDNSServer()

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.

I recently made a program that I added to the startup folder so it saves the times that I log in, the only problem is it saves after the last one so when I load the login time to another program the list goes from first log in time to most recent, so how can I reverse the order the items are displayed? I tried strreverse but it of course did not work.

This seems a simple enough thing to to but its giving me problems. What I have is this; a text box the user enters a word into, then a btnReverse that when clicked should cause the inputted word to display in reverse in lblReverse.Text. What seemed to me to be the easiest solution was this;

Option Strict On
Option Infer Off
