Finding max value in Two dimensional array???

:wave: Hey everybody.....are we ready for the superbowl?

I am working on a project where I have multiple tow dimensional arrays. I am trying to find the max value in the first "column" of my array. I have searched the net but I have only found ways to find the max values in a one dimensional array......can anyone help?

Is this what your looking for?

VB Code:

Dim aryString(15, 30) As String
aryString.GetUpperBound(0) 'Would return a value of 15
aryString.GetUpperBound(1) 'Would return a value of 30

Correct me if i'm wrong, but doesn't .GetUpperBound(0) return the last element in the array???

No... My array is as follows;

Dim Array1(,) As Double
ReDim Array1(30, 2)

The data in the array would look like this:

(0,0) = -36.5
(0,1) = 12
(0,2) = 6
(1,0) = -37.9
(1,1) = 9
(1,2) = 7
and so on.

I want to find the position of the max value in the first "column". For example the max of (0,0) -36.5 and (1,0)-37.9. In this case the position would be (0,0).

I think he means the highest value within an array. A multi-dimension array does not have "columns" as you may think. It is actually a matrix, so you will have to permatate each item like so:

VB Code:

Dim intArray(10, 20) As Integer
        Dim MeRandom As New Random
 
        For intIndex As Integer = 0 To intArray.GetUpperBound(0)
            For intInnnerIndex As Integer = 0 To intArray.GetUpperBound(1)
                intArray(intIndex, intInnnerIndex) = MeRandom.Next
            Next
        Next
 
        Dim intFoundOutter As Integer
        Dim intFoundInner As Integer
        Dim intCurrentHighestValue As Integer = -1
 
        'Check through the entire set to find the highest value
        For intIndex As Integer = 0 To intArray.GetUpperBound(0)
            For intInnnerIndex As Integer = 0 To intArray.GetUpperBound(1)
                If intArray(intIndex, intInnnerIndex) > intCurrentHighestValue Then
                    intCurrentHighestValue = intArray(intIndex, intInnnerIndex)
                    intFoundOutter = intIndex
                    intFoundInner = intInnnerIndex
                End If
            Next
        Next
 
        MessageBox.Show("Found highest number of " & intCurrentHighestValue.ToString & " at (" & intFoundOutter.ToString & "," & intFoundInner.ToString & ")")

Thanks a lot.... I am up and running now. :thumb:
