Apply Calculation To A 2d Array?
Mar 23, 2012
I have a 2d array and I want to do a calculation on each element in the array and then return the index which results in the smallest value.
I have tried iterating through each element in the 2d array and running the calculation. If the calculated result is smaller than the currently stored minimum I set that to the minimum.
This works but it runs so slowly it makes the solution a non starter. It performs each calculation quickly but because of the number of elements in the array the calculation for the whole array is stupidly long.

I found this thread in regards to calculating CRC16 on an array.... however, it does not work probably because it was written for VB6 and not .NET. [URL] Does anyone know of a built-in function in .NET to calculate CRC16? If not, is there a way I can adapt the above VB code example to work with Visual Studio 2010?

I am trying to work with taking in and parsing CSV files. Right now I have it taking in and producing something like this:
The program loads the csv and copies the data into an array as such:
ReDim strarray(num_rows, num_cols)
For x = 0 To num_rows
strline = strlines(x).Split(",")
[Code]....
etc. I guess my main problem is trying to perform calculations to all values in a specific column. To start I am just trying to figure out how to isolate the columns and found that by using MsgBox(strarray(x, num_cols)) it will msgbox everything in the second column twice. I just want to try and understand how I can perform a basic calculation like multiply every value in the first column by 2 and every value in the second column one by 3.

So I have an array which holds instances of a structure. The structure contains various string properties.
I'm looking to modify each instance of a structure within this array by doing the following:
For Each stuInstance As StuInstance In arrStuInstances stuInstance.strCarName = "Benz"
But I found that this in fact fails to really change it permanently. If I do the following loops in the given order:For Each stuInstance As StuInstance In arrStuInstances

I was knowing that For Each loop can only be applied to those classes that implement IEnumerable interface . But recently i accidentally wrote a code that is using For Each on my class's objects collection and my that class is not implementing IEnumerable interface .Below is the sample code that i am testing on :
Sub Main()
Dim personList() As Person = New Person(2) {}
personList(0) = New Person("s1", "s2")

I code GUIs in .NET frequently, and most of them only have the value of being a GUI, e.g. they don't do anything otherwise impossible. So most of the development goes to making them friendly, intuitive and eye-candy.Then it comes to my mind it would be simply amazing to skin them through .msstyles files, since there are so many places to find those files, and also tools to make your own.And some of those msstyles are just stunning, probably not for your whole desktop, but for styling homemade apps it would be perfect.

Is there a way to apply any changes made to an entire application and not just the open (active) form that you are in? I.E. I change the backcolor to a color from a color dialog. I want that chosen color to be applied to all the forms' backcolor in my project. Can this also then be applied to all the other controls' backcolor? The code that I posted works but all forms and controls have to have the changes applied to each one separately.

I am working in vb.net, visual studio 2010.
So i want to apply gradient to a square, a center to edges gradient. This is the code:
Public Class Form1
Private Sub PicSourcefrm(ByVal sender As System.Object, ByVal e As PaintEventArgs) Handles Me.Paint
Dim Graph As Graphics
[Code].....
NOTE: Picsource is just a PictureBox named that way. If I put "BrushSquare.SurroundColors = Color.Red" in a comment. The program works but the edges are white, not red like I want them to be.

I just want to verify something. I believe it is likely that if I apply the using command to a SqlDataReader, that it will both close the data reader and dispose of it. For example:
Using sdr As SqlDataReader = cm.ExecuteReader()
Dim someInt As Integer = sdr.GetInt32(0)
'other details and actions
End Using
Will that close the sdr SqlDataReader after it exits the Using code block. (I believe it will, but just want to verify.)

I'm working in VS 2008, on a windows application.I have many forms, and I'm in the process of redesigning the GUI.Is there anything that I can do to standard some of the placement of the controls. For example, I have a header for each page, at a certain size and location. Instead of going to each form, is there a way to do the settings once, and apply to many forms?
