Deal With Someone's Ugly Code Gently?

I've recently been given the task of finishing an incomplete project for my University. It'll count as credit for one Class so I'll shave a month off of my studies!
[Code]...
Methods returning numbers just for the hell of it, passwords being saved in plaintext, you name it.
I have a meeting with the original author and I don't know how to handle this situation because I'm quite green in this area. How can I tactfully mention that I want to rewrite the whole thing?

I am using VB 2005 and MS Access 2007.Some of business name has apostrophe(') and I need to know how SQL deal with this name.For example
sqlStr = "SELECT * FROM AddressTable WHERE BusinessName=" & "'" & updateBName & "'"
in this case, if updateBName is "Den's Nail", the real SQL is
"SELECT * FROM AddressChangeTable WHERE BusinessName='Den's Nail'"
and this code generates Error Message.Is there any way to prevent error ?Or do I have to remove all apostrophe(') in Business Name?

My app is basically talking to a device via RS232. I need to 'listen' to the data received and do certain things based on it, update labels, etc. When I started, I only had a couple cross-thread calls and I used JMC's example to get by that. Now my app is bigger and I am calling the ThreadProcSafe all the time. I am hoping there is an easier way so I don't have to create sub routines for every control. Here's the relevant parts of my code.
Private Sub StepperSerialPort_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles StepperSerialPort.DataReceived
Dim ReceiveBuffer As String

I was trying to add two quantities at different rows of same description i.e same product_name and same item_pack.1st I want to check the table if it contains the same description or not by comparing with the first record and so on. When found, I'll add up the quantities and then to delete that particular row (to avoid duplicate search). But when I delete the row the particular row, next time it throws an out of index exception

I've received a text file in which the text is like this, ãYAHOO.COM. When I'm debugging in Visual Studio, the value I see for the character is "�"c. Firstly can anyone tell what is the character before yahoo. Is it a special character or some html character, and what is the character that I'm seeing in VS while debugging.So it goes like this, the ascii value of the character turns out to be 63.But when I write the value to a file it generates 3 characters whose ascii values are above 127.

I've been trying to improve the efficiency of my giant program and I know that using a textbox to deal with a string is terribly inefficient.
Function CollectionSplit(ByVal TheString As String, ByVal TheSeperator As String)
Dim tb As New TextBox
tb.Text = TheString.Replace(TheSeperator, Environment.NewLine)
Dim returnable As New Collection
For Each x As String In tb.Lines
If Not x.Length = 0 Then returnable.Add(x)
Next
Return returnable
End Function
What it does is convert a string of "1,2,3" into a collection of the 3 separate items for use later on.

I am trying to write a VB .NET program that runs a Perl script and reads and uses the standard output. I'd like to be able to handle each line separately as it is printed, and update my program display accordingly. Here's some code I have "written" (read: "mostly copied off the internet"):
Private WithEvents pscript As Process
Private Sub myProgram_Load(sender As Object, e As System.EventArgs) Handles Me.Load
pscript = New Process()
[Code]....
This works with one problem: the program waits until the test script has run to completion, and then fires several OutputDataReceived events one after the other. This means that when I make it use the real script, it's likely to do nothing for as much as several hours, and then have to deal with, like, 5,000 events at once, despite the fact that stuff was being printed at fairly regular intervals throughout that time.
Is there any way I can make it deal with each line of text when it is written, instead of all of it at once at the end?

Suppose I have an interface IFoo with implementation classes VideoFoo, AudioFoo, and TextFoo. Suppose further that I cannot modify any of that code. Suppose that I would then like to write a function that acts differently based on the runtime type of IFoo, such as
[Code]...
Then I have to do my "If TypeOf ... Is" again. How can I refactor this to take advantage of the polymorphism of the implementations of IFoo without manually checking the types? (in VB.NET, though my question applies to C# too)

Sounds simple enough, but its not working. In this example, I want to set the values of 3 fields to equal a 4th. I could do something like this..[code]...
Values in the param array did not get updated in the return! I was expecting to have all of the final values now be "1", like they are in the Function.
Is there any way to get an update-able ParamArray collection like this? ParamArray must be declared ByVal, but with a reference type like String, shouldn't that only make a copy of the pointer and allow me to change the underlying value?

My main goal is to have an excel spreadsheet that automatically plots the overall success of my stock portfolio over time (% change over time). I've been able to incorporate stock data into my spreadsheet by linking it to the web, but the trouble is the spreadsheet will keep no history of what the previous stock values were, so I can't graph how things change over time. This sounds like it might be too complicated to be built in to excel, so I was wondering if anyone knew how to program this in Visual Basic. Maybe something like this.... If refresh then new cell plus new time stamp. Another possibility would be to have a whole bunch of cells that refresh only once but at longer and longer intervals, e.g.,
Day Stock value
1 refresh at Day 1
2 refresh at Day 2
3 refresh at Day 3
etc..

I am making a program to deal with sine/cosine functions
If rdbsideA.Checked = True Then
Do While AngleB > 0
SideA = (SideB * Math.Sin(txtAngleA.Text)) / Math.Sin(AngleB)
Loop
MsgBox("The Length of Side A is ", SideA)
End If
That is if the user seleects to find side a. When the messagebox pops up, it doesnt state the previous calculation, why is that?

I have handed this assignment in and it works albeit not in the most elegant way. I am taking my second programming class ever and I would love for some feedback and answers to a few questions i have. First, what would be a better way to display the correct image to the corresponding card. Using all those if statements seems ridiculous, but i cant see a way around having card 1 possibly equal each value from every suit, card 2 equal each value from every suit, etc.
Second, my professor wants us to be able to record the seed value so that we could then plug it back in and return the hand that was shown when it was created. i have done this but I am a bit confused. The seed shows up as a value from 0-999, but when you use the combination formula to figure the total possible amount of hands you get over 2.5 million. Since i only have 1000 seed values does that mean that multiple hands might share the same seed value or does that number (0-999) mean something different eache time? Sorry if my explaination seems confusing.
Third, I am always looking for advice on better ways to do things. If anyone has free time and would like to offer constructive critisism I would be grateful.Below is the code. I only left in picturebox display for 1 suit so as to shorten the total amount shown. I also removed code for other buttons and stuff.
Public Class Form1
Private Sub btnShuffle_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnShuffle.Click

Dim intSuit As Integer ' Row
Dim intCardValue As Integer ' Column

so I've come across something which is perhaps a flaw in the Extension method .CopyToDataTable. This method is used by Importing (in VB.NET) System.Data.DataTableExtensions and then calling the method against an IEnumerable. You would do this if you want to filter a Datatable using LINQ, and then restore the DataTable at the end.

Create a class to deal with records from the Classes table, much like the Student class we created in Lecture #17 handles Students records. The name of the class should be Ualb_Class (note we cannot use Class, as it is a reserved word in VBA). All of the fields should have corresponding properties. There are few considerations:
The class (course) code, department code, and course number are set at Initialize, so there is only a Get property method for those
The property for Meeting Day only accepts one of the values defined in the table. You can decide whether to accept an integer value or a string value of the days represented.
You are also to code the Initialize method, much like we coded the Initialize method for the Student class in Lecture #17. In the Initialize method, you will use the InputBox function to obtain the department code and course number. use a different InputBox for each value, so you don't have to mess with separating the single text value returned from that function. The Course Code will be obtained by using a function that has already been created, called GetNewCourseID. It has no parameters.

I want to retrieve total value from sales table in sqlcommand object. Below is my sample code.I will get error if there was no data in the tabel that matched my query saying that null could not be converted into decimal.
I would not get error if there was data that matched my query and returned the total value in tmpSales variable.My question is what is the best way to deal with this situation?
Dim CmdTmp As System.Data.SqlClient.SqlCommand
Dim tmpSales As Decimal
CmdSales = New System.Data.SqlClient.SqlCommand("SELECT SUM(Total) FROM Sales WHERE Date>= '1 Jan 2011' And Date<= '30 Jan 2011", ConDB)tmpSales = CmdSales.ExecuteScalar
