How To Model An Array Function To Fit My Script
Oct 26, 2009
I am in the process of using a two-dimensional array to find wind chill factors. My application uses a nudTemp for temperature and nudWind for Wind Velocity. When temp and wind are chosen from the nud list, it is supposed to display the wind chill temp in a text box and then display a message box. Right now it does everything it is supposed to do except that it does not display the proper wind chill factor.
I know it is an issue with my arrays so I was provided with an example but I don't know how to modify it so that it matches my code. I have added all of the array values but it is naming the array variables I am having issues with.
Sample code I was provided:
Private arr1 As Integer() = New Integer() {10, 20, 30}
Private arr2 As Integer() = New Integer() {100, 200, 300}
[CODE]...
I have provided my code as I have it thus far, listed below.
Option Strict On
Public Class frmWindChill
Dim intWindChill(7, 5) As Integer
[CODE]...

I'm trying to get a query string from a shared function in a code-behind model using VB.NET. You have to use HttpContext.Current.Request.QueryString("Query") in order to get it from a shared function, however doing HttpContext.Current.Request.QueryString.Count gives back 0, which obviously isn't right in my case as there's many that exist. Is there some sort of issue with using this static call from a shared function?

I need to create a Digital terrain model from ESRI ASCII grid format into an array. First I need to use the column and row values (from the header information) to read into my file to specify which values to put into the array. I think i have to use both counters simultaneously, and although Ive read in the first line (columns) I can't get the next line in. Do I have to use a counter under a different name, and can I do it in a nested loop?
vb.net
Private Sub Input_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Input.Click
dlgOpenASCII.ShowDialog()
filename = dlgOpenASCII.FileName

I am creating a dll with all the functions and subroutines that I use all the time and I decided to create a function that I can pass different types of array to so the function obviously (or not) would have an array of type object. Now I no you can pass any type into an object type but when I pass an integer array into an object array I get an error.
value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.
Shared Function CompareArray(ByVal FirstArray() As Object, ByVal SecondArray() As Object, Optional ByRef ErrorMessage As String = "") As Boolean
Dim IntArrayOne() As Integer = {1,2,3,4,5} Dim IntArrayTwo() As Integer = {1,2,3,5,6} Dim IsSame As Boolean = False IsSame = CompareArray(IntArrayOne(), IntArrayTwo())

I would simply like to know if it is possible to call a function using a string value.
As an example i have many functions called "openford","openvauxhall","openmini" etc.
So what I mean is, can I put all those function names into an array, then pull a name from the list and call it.

Before adding rows to a table I am evaluating the SSN number. These will later be flagged for correction so I am setting a datatable column to true or false if it passed muster or not.
I wrote a function to check the number and make the determination plus pad it with zeros and hyphens where they should be. My problem is I want to return the results in an array. I am getting system.string[] as the return value.[code]...

I have a Sub with an array of strings as parameter:
Private Sub des(ByVal array() As String)
Dim i As Integer
For i = 0 To UBound(array)
[code]....
When I call the function inside my main function , the value of str changes even if the array is passed to the function Byval
Dim str() As String
str = {"11111", "22222", "33333", "44444", "5555", "66666"}
des(str)
I tried making a copy of the array in the Sub, but it still changes in the main function
Private Sub des(ByVal array() As String)
Dim i As Integer
Dim array2() As String
[code]....
I read on a site that you cannot pass arrays ByVal ,is this true? If so , how should I proceed?

I have a multidimensional array (not jagged array) that saves data from rows and columns of an excel spreadsheet. After it completes recording the data from Excel, I need to pass the array to another function.I understand how to pass a jagged array, but not a true multidimensional array.
Can someone point me in the right direction? I've done some searching on this site, and others, but most of the info only includes single dimension arrays or jagged arrays.
