VS 2010 Returns In A Using Statements - Do They Trump One Another?
Oct 30, 2011
This is just a simple question I'm sure, but while coding I just realized that possible this could cause me some problems. My knowledge still of Using blocks and returns is fresh. But as far as I know once you return something, everything stops dead in it's track because you have your answer and theres no need to continue.
So I was wondering if I had a Using statement and a return nested within it does it still process the using as should? IE. disposing and cleaning up resources afterward.

Can someone give me a site to a tutorial that will help me write a program that will generate a pattern using do while, if else statements,and do until statements.

I have just installed VS 2010 Premium on my Windows Vista Machine. I've noticed that in VS2008 when I typed for eg " Public property MyProperty() as string " and pressed the enter..I was getting automatically the expected result. Meaning by that , that VS2008 was generating for me the rest of the code. [code] In Visual Studio 2010 I am not getting this anymore. What happened ? Is this feature still working in VS 2010 ?

Im making a login system that encrypts and decrypts the username and password. My encryption code is:
Private Shared Function enc(ByVal targetString As String, ByVal maskvalue As String) As String
Dim Index As Integer = 0
Dim ReturnValue As String = ""
[code]....
The enc function works for both encrypting and decrypting (I've tested with a MsgBox alert. The problem I'm having is when the program loads, it reads the file and decrypts it. However, instead of properly working, it returns one character in the first textbox and nothingin the other without any error being thrown.

I have a class that inherits List<T> [this is a C# project, but it can relate to VB.net] but I want to know if there's a way to force the index to return something else....let me give an example:
In the original List<T> implementation, whenever you call for an item on the list, like so:this[0];You get whatever T is. What I want to do is override that, and grab whatever T is, then return a certain value of T.

Code Block 1 First I am calling my function to obtain a pixel color at a specified coordinate.[code]The odd part is while looking at the results as a string they appear to be the same, but while using If Not TheColor.Equals() in code block 2 the program returns that they are different. Before threading code block 2 this was not a problem so I can only assume the threading is causing the problem. I'm unsure as to how I can fix this... Additional unrelated problems I am having are:
- On WindowsXP the colors being read are not the actual color as which the mouse is located.
- While using print-screen there seems to be a bit of lag and some times unreliability, is there another method to get a pixel color at a specified location? Note that GetForegroundWindow works on Vista/7 but not XP, and GetActiveWindow is unreliable.

By my logic, this should only assign .length to index IF the length of strItem is longer than 0. This check is there in case the listbox is empty, or the user has not selected an item. However, everytime I go through this code without an item selected I get:

I have a vb.net app that I can read a .xls file into a dataset or loop through as oledbdatareader and it gives the same result.Some of the rows have all nulls when I loop through them but if I open the same file in Microsoft Excel I can see that row fine.[code]From the info above the first two SKU values would come through fine but when I get to the 3rd row it would show a null.Is it possible that it kind of inherits the first rows type and since the 3rd row isn't all numeric if nulls it?

Strangely, if I use the OpenRemoteBaseKey method it works BUT I don't want to use that because using WMI lets me specify alternate credentials and OpenRemoteBaseKey doesn't

I am working on a simple vb project to read data from a PC serial port and write that data to a file.The data is ascii sent in Hex format. I used MySerialPort.ReadChar() to read data and MyStreamWriter.Write(MySerialPort.ReadChar()) to write it to a file.
I copied my code below, sorry about the format.The trouble is: MySerialPort.ReadChar() acts the same as MySerialPort.ReadByte() , both takes the Hex data input and returns data in decimal format.I tried to use Convert.ToChar(MySerialPort.ReadChar()) to covert decimal to char, but it's too slow.I tried decimal.ToChar(MySerialPort.ReadChar()), but VB doesn't recognize decimal.ToChar, even after I installed .NET4.
Did I do something wrong? how to make MySerialPort.ReadChar() to read Hex data and return char?

I have a project to make a "3x3 magic square" and I'm not quite sure how to begin. A magic square is a 3x3 table of 9 values where the sum of the values along any row, column, or either diagonal all add up to the same value.I have to use listboxes to create a form displaying a table of 3 rows and 3 columns whose elements can be individually updated. The solution should have the following features:
- a procedure that initializes a Listbox to hold the value "?", representing the value "undefined", in each of its locations. The number of locations should be provided as a n additional parameter.
- a procedure that will update the contents of a listbox by replacing the currently highlighted entry with a value provided as a second argument. The program should at most have at most one entry among the listboxes highlighted.
I am trying to use a Function that returns an integer value: -1 if not all the elements on the table contain values, 0 if the rows/columns/diagonals don't sum up to the same value, or the sum common to all the rows columns, and diagonals is returned if everything is alright.The user will enter a 3x3 set of numbers. The program will monitor the status of the table as values are entered and displays the status in a textbox that describes if a magic square currently exists. If not all the entries have been made to the table, then the textbox should display a message indicating so.

I have some code which gets child items for a menu via the GetChildren function which takes a list of menuData: Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu
If menuData.Children IsNot Nothing Then
menuData.Children.AddRange(GetChildren(menuData))
End If
Next
If I check if menudata.children isnot nothing, it always is nothing because the GetChildren function is yet to run (providing the child items, which do exist). If I remove this check and just have this code:
Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu
menuData.Children.AddRange(GetChildren(menuData))
Next
Then I am presented with a Object reference not set to an instance of an object error on menuData.Children.AddRange(GetChildren(menuData))

I am using Microsoft Visual Studio 2008 with VB.NET, and in class we were assigned this project: A procedure should calculate a 2% price increase on all red shirts, but a 1% price increase on all other items. In addition to calculating the price increase, the procedure also should calculate the new price. You can use the variables strItemColr, strItem, decOrigPrice, decIncrease, and decNewPrice. Format the original price, price increase, and new price in the lblOriginal, lblIncrease, and lblNewPrice controls, respectively.
