How do I determine from these codes in a one dimensional array named sales which will refer to the ninth element?
sales(8)
sales(9)
sales.Item(9)
sales(10)
My thought is that the 3rd code will refer to the ninth element in the array.
Write the statements to declare a local one-dimensional array named intNumbers.The array should have 20 elements
B. Write the statement to store the value 5 in the second element contained in the
intNumbers array
C. Write the statement to declare a form-level one dimensional array named mstrProducts.
The array should have 10 elements.
D. Write the statement to store the string "Paper" in the third element contained in the mstrProducts array.
For my programm I am supposed to store the minimum points in a five-element, one dimensional integer array name points. And I need to store the grades in a five-element, one dimensional string array named grades. These arrays should be parallel arrays. I am supposed to code the display grades button click event procedure so that it declares both arrays. It also should search the points array for the number of points entered by the user, and then display the corresponding grade from the grades array.
Here is my code:
Option Explicit On
Option Strict On
Option Infer Off
Public Class Grades
Private Sub exitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles exitButton.Click

I am working on a very basic draw poker program. I need to analyze the hands. So far I have been able to identify a a pair, straight, a flush , and a straight flush. I'm not sure how to find three of a kind, full house, etc I have a function that uses a hash table to find out if there are duplicates in my array. I can use it identfy a sequence of cards. (i.e. if it returns a 5, that would be five cards in sequence) I'm not sure how to/if at all to use this for a pair , three of kind etc.. Maybe a differant approach would be useful. I've tried various pseudo code idea on paper and just don't see it.

unordered text file of 3 columns to assign into 2 arrays. I've been given a graphing component which expects a two dimensional array for a scatter graph for the set of values in the last column.
How would I parse through the list given an indexed array of 215 possible 'zone alarm locations' and if an alarm log list item, of which there can more than one for any given zone location, compare in the two dimensional array any previous value and replace it with the higher valued one? The following are my declarations for the 2 arrays. It isn't clear to me why the array for the scatter data was defined as (999,1) knowing there are only 215 possible x values (alarm zone locations)

I am having problems finding an named object declared in XAML in my codebehind file.I want to initalize a ViewModel from inside my View. However I also need a reference to the ViewModel in my code behind file (basically for navigation support, handling events, etc. that I cannot do easily from my ViewModel)[code]However I get a null reference exception when I'm trying to access the ViewModel in my code behind:[code]Some more research shows that the FindName call for "ViewModel" in InitalizeComponent returns null. I tried reading up on XAML namescopes etc. but as far as I see, this should be a simple case and just work, no?
View 1 RepliesI have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

I'd like to know if it is possible to refer to section of an array. e.g.
dim a(10) as integer
foo(<reference to array a starting at item 2>) 'only use items 2 to 9 of the array
...
sub foo(byref a() as integer)
<do something with array>
end sub
Note that I don't want to copy the array to a new array or pass in indices, if I can avoid doing so. Subroutine foo should be able to process the array without knowing if it gets the whole array or just a section.

I need to read a named range into an array. Then if the value in the 1st position matches a static value, read the value in the second position. I've been looking into array's and this is what I think will work, however I get a compile error on the columns.count "constant expression required". Is it because in the DIM statement I'm attempting 2 things? This is a macro in Excel. The range name is Data1 and the string comparison is "AnyString". The second value will be an integer.
