A-Level Computing Exam Arghhh
Mar 6, 2011
I have been given the prep material for my AS Level (Year 12) computer programming exam based around dice cricket. Written in VB 2008.
In the exam we are supposed to change bits based upon the scenario. The scenario and skeleton code are attached.
I have looked through the code so far and made some guesses to what I think may be on the test:
[code...]
if there is anything I am missing which they think I could be asked on the test. I then have to go away and figure out how to program.
So by asking on here, I am not trying to find out coding answers - I do want to figure that out myself. I just want to see if there is anything else I possibly could be asked?

I have just started coding my Computing project for my A-Level, and I will admit, I am far more experienced in VB6 than VB.NET (as embarrassing as that is to say).I get extra marks for making everything presentable, so was wondering if it was possible to add icons into .NET buttons. For example if I have a button to add an entry to the database, I want a nice Web 2.0 looking icon (for which I already have) next to the text on that button.

I'm not looking for anyone to complete my "home work" assignment for my A-Level computing as I've done this now and I think it's impressive. What I am now looking for is help in extending what I have done and making it better.
History:I have built my application in Visual Basic 2005 Express Edition. It is a Console Application. After filling in the questionnaire the user gets given results and all this information is stored in a .txt document (Notepad). I want the data that is put in to the application to send infomation to the user's e-mail address. I have been looking around the internet and it says it could do it but it needs Outlook express.

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.

In Visual Basic 2008, there's two different ways that I know of to accomplish the same thing:The Dim on the member level:
Dim counter1 as integer = 0
Dim counter2 as integer = 180
Public Sub SampleSub1()

I have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.

First off, this is not for a class. Although I *AM* taking VB classes, I wanted to do something on my own that would help me learn. I find that the examples and assignments in class, are okay, but I would like to do something that I could apply in real life, perhaps apply it to my own work and master many techniques. So this could actually become my own final exam
That being said, I have searched and read all the posts on quizzes and tests and they are usually asking for code answers. No from the beginning development and planning. I am sure eventually, I might ask some code questions, but I would like to start at the beginning and analyze, develop the algorithm/ flow chart, and desk-check first.

I am trying to make a program that can calculate the percentage of people passing an exam. There are buttons for each letter grade, and working label counters for each time you press a button. Each button looks like this, except replace the letter with the appropriate one.
Private Sub btnA_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnA.Click
Static intA As Integer = 0
intA = intA + 1
lblA.Text = intA
lblPercent.Text = (lblA.Text + lblB.Text + lblC.Text + lblD.Text) / (lblA.Text + lblB.Text + lblC.Text + lblD.Text + lblF.Text)
End Sub
My problem is that the percent does not equal what I get when I put the exact same numbers into a calculator.

I'm trying to compute 100! and there doesn't seem to be a built-in factorial function. So, I've written:
Protected Sub ComputeFactorial(ByVal n As ULong)
Dim factorial As ULong = 1
Dim i As Integer
For i = 1 To n
[code]....
Unfortunately, running this with the value of 100 for n rseults in
Value was either too large or too small for a UInt64.
So, is there a larger data type for holding numbers? Am i mistaken in my methods?

I love to experiment with linqpad, but now my task requires heavy computing power. Trying to do it on my computer is painful. My friend has a much more powerful computer than I -- can I execute some operations from my linqpad on his computer? I don't have RDP access, but I can run any .NET program on his computer.
If it is not possible, then is there any FREE service that provides computing power? Maybe a hosting trial or something. I know that Windows Azure offers a 30-day trial, but it has a very slow CPU module and in my country, MS partners cannot be expected to fix service sites when they go down.

How would you take a numerical input from 10 text boxes and total it up and send it to a label. Then average the 10 numeric text boxes and send it to its own label. I am not asking for any code, I just need a hint or two to jog my memory. If this is not clear for you, I'll provide more detail.

I have multiple level of For Each and in each level, i have a Linq that is the 'In' criteria as in:
[Code]....
It will go inside each for (because the value is not nothing), however, it will only loop (next) in the very inner 'For Each t In tFor'. After it is finish inner loops, the outer Fors' or Next will not execute... even thought there are more than one values in that 'In'... like 'sFor' or 'fFor'. i've noticed while debuging, while break at the for (for example 'sFor', before stepping in), i get the error message:
"Enumeration yielded no results" when i expand the result for that variable and it will not step into it. but if i do not expand the result, it will step in. It seem that some how, once an element is accessed for that 'In' collection, it breaks (meaning does not loop for the rest of the elements) the next for that collection is this a bug or am i missing something in Linq? BTW: i believe it has something to do with the SqlDataReader in the Linq. I'm working with IAsyncResult.

I've had experience with using hashvalues from String objects. E.g., if I have StringA and StringB both equal to "foo", they'll both compute out the same hashvalue, because they're set to equal values. Now what if I have a List, with T being a native data type. If I tried to compute the hashvalue of ListA and ListB, assuming that they'd both be the same size and contain the same information, wouldn't they have equal hashvalues as well?
Assuming as sample dataset of 'byte' with a length of 5
{5,2,0,1,3}

I am trying to write code to compute the Efield on a point P in both the x and y direction, from a charged ring. double y_eField = (_ke_value * _dq * (Sin_angle) / (Math.Pow(r, r)));Problem I am having is the code seems to follow the equation as given but the result it outputs is not correct at all.

I have a server that runs a thread that computes some data through function X. Then I have a client that communicates with the server and gets results from function Y. Now, both function (X and Y) share a common variable lets say varZ. When function X populates varZ when the thread starts on the server, the results are not propagated on function Y when accessed by the client through Remoting. But on the server side the results are correct in function Y! It's almost like when client calls function Y, it has no idea what is happening varZ is as far as the value set by function X thread in the server.
