VB 2010 - "3x3 Magic Square" - Use A Function That Returns An Integer Value?
Mar 16, 2011I 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.

Error After Implicit Conversion Of 1 Dimensional Array Of Integer To IEnumerable Of Integer() ) ?
Apr 25, 2011I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?

May 13, 2009I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.
After the conversion, the code look like this:

Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

Value Of Type 'System.Linq.IQueryable(Of Integer)' Cannot Be Converted To Integer?
Aug 11, 2011I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:
Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)
[Code]...
I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

.net - Comparing Integer And Integer Results In Boolean?
May 28, 2009I'm just writing a bit of code to compare an id of integer with an id of integer? for example:
Dim id As Integer = 1
Dim nullId As Integer? = Nothing
Dim areEqual As Boolean
areEqual = nullId = id
When I try to compile the code I get a compiler error: Option Strict On disallows implicit conversions from 'Boolean?' to 'Boolean'. Whilst it's very simple for me to work around this, I was hoping that someone might be able to explain what's going in the compiler to give this warning.

View 1 RepliesSquare Feet Using Arrays?
Aug 19, 2011I need to take a minimum and maximum value from the user for length and width using an array(s) and display the square feet of all values. Since the values can be any number the array(s) size cannot be defined. In my form I have 4 text boxes (MinWidthTextBox, MaxWidthTextBox, MinLengthTextBox, MaxLengthTextBox). I have been able to take the text from each text box and initialize 2 separate arrays with those values, however I am completely lost on how to get the square feet from each element. In other words I don't know how to do this:
WidthArray(0) * LengthArray(0)
WidthArray(1) * LengthArray(1)
WidthArray(2) * LengthArray(2) etc. etc.
I don't know if that is possible or if I am over complicating things.
Here is the code I used for my arrays:
Dim WidthArray() As Integer
Dim LengthArray() As Integer
Dim MinWidthInteger, MaxWidthInteger, MinLengthInteger, MaxLengthInteger,
[Code]......
In each For loop I can output the elements to a listbox for text and it works but again I have no idea how to multiply each element to one another to get square feet. Should I be using a multidimension array instead?
