Turning List Into Array
Feb 1, 2009
i have a simple list Format
[Code]...
Its extracted from a text document and put in a multi line textbox in the same format. What I want to do is read each line and put it in an array, however i couldn't find code to read line by line, so I have a series of questions
1. What code do I need to put in an If statement so if it is a return (i.e. the next line) Then it runs
2. Is there a simple way to read line by line in multi textboxs so I don't need to do question 1

Basically, my program is supposed to display the list of students that have been entered. (Into a listbox.) Here's the AddStudent code (which works as far as I know)
Public Sub AddStudent(ByVal FullName As String, ByVal Gpa As Integer, ByVal Major As String, ByVal SocialSecurityNumber As String)
_FullName(ENROLLMENT) = FullName
_Gpa(ENROLLMENT) = Gpa[code]......
Here's where the problem comes in...I need to return a value from "GetAllStudents" that can be used with the lisbox. Here's the code for that:
Public Function GetAllStudents() As String
Dim i As Integer = 0
Dim aryStudents(50) As String[code]....
This obviously doesn't work. It gives an error that I can't convert a 1dimensional string to an array.

I have a small 10px by 10px image, and I want to use VB.NET to find out if that image is (an exact) part of a larger image.I thought a method of doing this would be to lock the bits of the larger image into memory and then loop through each pixel in the image and for each pixel, I could take the 10px by 10px section which is down and to the right of that pixel.. and then compare it to my smaller image.
This is the code I have so far:
'Lockbits of larger image to memory
Dim bmp As New Bitmap(Image.FromFile(System.AppDomain.CurrentDomain.BaseDirectory() & "picture.bmp"))
Dim pxF As PixelFormat = PixelFormat.Format24bppRgb
[code]....
when I'm looping through the 10 by 10 section and I find the R G B bytes for each pixel, how do I store this in my rawImage array so I can convert it to a back bitmap and compare it with my original small 10by10 image?

I have been tasked to create a Visual Basic console script that asks the user 5 times in a row to input a number into an array (sales figures in thousands), Then you display these results as a sort of tally chart.
For example for the data: sales(10,7,12,5,15)
The output would be
2008:++++++++++
2009:+++++++
2010:++++++++++++

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

I am trying to get a count of all the times a byte sequences occurs in another byte sequences. It cannot however re-use a bytes if it already counted them. For example given the string let's assume the byte sequence was k.k it would then find only 3 occurrences rather than 5 because they would be broke down like: [k.k].[k.k].[k.k]. and not like [k.[k].[k].[k].[k].k] where they over lap and essentially just shift 2 to the right.
Ideally the idea is to get an idea how a compression dictionary or run time encoding might look. so the goal would be to get down to just 2 parts, as (k.k.k.) is the biggest and best symbol you can have.
Here is source so far:

I have a class called Car. Car has a bunch of properties i.e. Car.Color. CarService has a method called GetCars(). Within GetCar, I have a loop that appends a List of, you guessed it.. Cars.[code].....
I get: Value of type '1-dimensional array of Namespace.Car' cannot be converted to 'System.Collections.Generic.List(Of Namespace.Car)'. What would be the best way to convert this 1-dimensional array' back into a List of Cars?

I'm trying to use System.Diagnostics to do some very basic logging. I figure I'd use what's in the box rather than taking on an extra dependency like Log4Net or EntLib.
I'm all set up, tracing is working wonderfully. Code snippet:
Trace.TraceInformation("Hello World")
App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
[Code].....
That doesn't make sense to me: I just have to declare an instance of the BooleanSwicth to be able to manage (disable) tracing via the .config file? Should I like ... use ... the object somewhere?

My coworker's installation of visual studio 2008 breaks every time there's an exception, mine doesn't.
We've been looking for how to stop his from doing this but haven't had any luck. The only difference is that mine was initialized for C# while his was initialized for VB.
Other than reinstalling and choosing the option that says "Optimise for C#" when VS2008 sets up the environment for the first time

I am supposed to be writing a program for my instructor using VB 2008. It is sort of like a quiz program. You build the "light bulb" program but instead of names and colors, it consists of two forms. Question 1 with a "next" button and the second form for Question 2 with a "previous" button. I have no idea how to link the two so that when you click "next" it goes to the second page and vice versa.

I am creating pivot tables in VB.NET and have run into a problem I did not think would be as difficult as it is turning out. When I create a pivot table it adds in subtotals for each row and I do not want that. In excel you just drag down the subtotals option and tell it to not display subtotals. I looked into the VBA for it and it is several lines long of this format:
ActiveSheet.PivotTables("Main Highway Pivot").PivotFields("Division"). _
Subtotals = Array(False, False, False, False, False, False, False, False, False, False, _

I'm trying to build an application to increase my understanding of visual basic. I may have set the bar too high for myself but it's the challenge that makes it fun right? Anyway, I'm trying to make a transition effect of a page turning. The application is a brewing database which looks like a book. I think the transition would make it look more professional. Dose anyone have on how I might be able to accomplish this? A basic example even would go a very long way.

A week or so ago, you folks really taught me how to use the KeyData event. I adopted some of the coding to make my new code so much better. A few days ago, I thought I figured out how to run my little game. You see, you have two buttons. Comment and Uncomment. You Press Control + K and then after that, you press Control + (C or U) to activate the buttons. And I thought it worked! But my buddy figured out how to break it! The thing is, I need to figure out a way to make IsCtrlK (Look below) False if any key that isn't Control + C or U is pressed right after it. What would you suggest I look into using?
