i am new at everything VB.net/ASP.net. I have an ASCX.vb page that lets the user choose someone from a table. Once they do select someone, the page reloads with that persons information into another table below that one where they can submit an order for that person or remove that person. Problem being is that i wanted to store the users ID that are selected but it seems that everytime the page reloads to show an update, it dim's my array again back to default. This is my code once they choose a user:

I have a lot of forms set up, probably about 10-15 so far (more to come). Some forms 'lay' on top of other forms, and each form contains multiple controls. I am discovering that my approach is not very likely to succeed in what I am thinking of doing.
Here is one example: LeftControlPanel form contains 5 controls, but 5 other forms 'lay' on top of it and use transparencies to load up bitmaps. Since I cannot parent the forms that 'lay' on top of the form, I cannot figure out a good way to move them.Is it logical that when I move LeftControlPanel to a different x location, I would just move all the forms that 'lay' on top of them as well?Seems like a clunky approach of moving one form since parenting the transparency forms will remove all the transparencies that are set up...
Is there a bit better logic I might be missing, or bite the bullet and start moving multiple forms at once?

I have an MDI running as the parent. How can you stop the forms moving to the back when they are open if you click in the any part of the MDI area. Also I notice if I have more than one form open it creates form instances on my windows task bar?

im having some trouble with my loop code. When the isnumeric code detects it not a number it throws the msgbox error message but moveson to the next array for the user to enter a value via inputbox. Is there a way for the program to send the inputbox asking for the value again before moving to the next array?

I'm making a quiz and I've got a set of questions and answers being loading into two different arrays, the idea is to answer a question with a choice of 4 buttons, so on a button click the answers checks to see if it is correct and moves along to the next question (while doing this the questions and answers change)However, my problem is that i've set up an audio player as the questions are for example "what is the sound?" and there is a preview button which uses the audio player to play the sound for the user.
Now everything moves with the array however, the sound still remains the same on every question after the quesiotn has been answered. So my set of answers move (when debugging, the sound array does move but the player doesn't seem to want to) with the array and i need the player to change to the specific array position which it is in as well.
Audio Player:
Dim answer = CorAnsList(qNum).sound
Dim answerPrev As String = My.Computer.FileSystem.CurrentDirectory & "sounds" & answer & ".wav"
Private Sub btnPrev_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPre.Click

I have an application (written in VB.net 2008) which reads a text file. Parses the record and uses the second field (a UK postcode) to match an Access database (SQL - Select * from Table1 ......), then writes a text file back out with the original input postcode plus several fields taken from the access database.
I have 3 counts happening during the process, records read, postcodes matched and postcodes not matched. I move these values to labels on the form, then every 50 records read, I refresh the form (me.refresh) to update the labels (showing the end user where the process is upto).When running, if I drag the window around the screen, or minimize then maximize, or click off the window to another window, the application seems to freeze and the counter labels do not refresh.

I'm currently working on a project for university, basically we were given an incomplete program to finish off with bonus points for adding addition features in.Part of the program is to move an image (a monkey) around the picture box (pen). Now to move the monkey we use 4 buttons on the form called Up, Down, Left and Right, however as we need to move the monkey around to test other parts of the program it gets annoying having to click on the button. As such I was able to get some code which allows me to move the monkey around using the arrow keys (I think you can all see the benefit of this). When I use the code in a blank form it works fine, however when I add a button onto the form the arrow keys will instead highlight the buttons.basically set up a button to disable all buttons on the form until a certain key is pressed, however I would prefer not to have to do this.

How can I update and get values in a Windows Forms application while moving one form to other form (like cookies)?
I need to update the values to some variable and again I am going to refer stored values and need to do some calculations.

How can these issues be resolves?

Basically I want to find the first occurrence of one array in another. I have tried using the Array.IndexOf Function, but it always returns -1. Example:
Dim array1 As Byte() = {1, 2, 3, 4, 5}
Dim array2 As Byte() = {2, 3}
MsgBox(Array.IndexOf(array1, array2))
Even though array2 does exist in array1, the message box always shows -1

I'm just testing things and seeing if I can get things working and if I can then I want to try and develop this into something more. So far its just a simple button1 finds all files with extension of .mp3 in C: and displays all the findings in a listbox. I then want to use button2 to copy or move (I want to see how to do both) all of the files that are in that lisbox to a directory of my choosing. Here is what I have so far.
Imports System.IO
Public Class Form1

Alright, so I need a method that traverses all the forms inside a VB.net project under Visual Studio 2008, and create an array of type form with references to all the forms inside it, so that the array looks like this (pseudocode)
FormsArray() = [Form1, Form2, Form3, Form4]
However, I don't have a clue as to how to begin.

I'm starting to learn arrays, but I'm a little bit confused on how to call the data listed in them.I have the following code in a module and was wondering how I call them in my forms.I was told to use a counter to keep track of where the User is in the code in order from them to navigate correctly. I'll be using Next and Previous buttons.
Public FormList() As Form = {frmMain, frmStartup, frmUninstaller, frmAutomation}
Public CurrentForm As Integer = 0

Dim images = dir.GetFiles("*.jpg", IO.SearchOption.AllDirectories)
