[RESOLVED] [2005] Extracting maximum and Minimum Value from a set of values

[surya]

I have a function that return 10 variables;

Is it possible to extract max and min values of these variables

a=5
b=6
c=8
d=4
e=3
f=2
g=1
h=9 etc

Max val = 9
Min Val = 1

Could you add them to an array or List (of Integer)?

Then you would simply to a sort and get the lowest and uppermost bounds.

i don't know much. But i can give you an idea.
Use an array instead of so much variables
then sort it by using ..................... arrayname.sort()
Use it's first and last value for minimum and maximum value.

[NPassero]

Dim myArray() as Integer = { 5, 6, 8, 4, 3, 2, 1, 9 }
Dim Max as Integer
Dim Min as Integer
 
Array.Sort(myArray)
 
Max = myArray(myArray.length - 1)
Min = myArray(0)

If you have any questions about Arrays just ask.

Hello Passero,
Many thanks for your response.

As these values are available in a variables,
How do I append them to myarray()?

How do I append them to myarray()?

Just use a List(Of Integer) instead like mentioned above.

Dim list As List(Of Integer)
list.Add(a)
etc...

Dim list As List(Of Integer)
list.Add(a)
etc...

Below syntax seems to be wrong, can you please check?

myArray.add(x)
myArray.add(y)
myArray.add(z)

[stimbo]

Dim x As Integer = 5
Dim u As Integer = 3
Dim s As Integer = 9
 
Dim myNums As New List(Of Integer)
 
        myNums.Add(x)
        myNums.Add(u)
        myNums.Add(s)
 
        myNums.Sort()
 
        MessageBox.Show(myNums(0).ToString)  'Lowest

thanks a lot stim,

I am trying to extract the max value using

Max = myArray(myArray.length - 1)

I am getting error.. Can you please correct me...

[stimbo]

As long as myArray is a List (of Integer) rather than an array it would be:

Max = myArray(myArray.Count - 1)

[jmcilhinney]

May I make two suggestions?

1. If something is not an array then don't name it "myArray".
2. Don't post that you get an error without posting details of the error, most specifically the error message.

[surya]

Many thanks Stim & stimbo

I was using Max = myArray(myArray.length - 1)

instead of Max = myArray(myArray.Count - 1)

Thanks a lot all of you...

thanks jmc for the suggestion

Hi,
One last question..
Is it possible to remove the duplicates in the string...

thanks

[NPassero]

Dim myString As String = "hello"
      Dim i, length As Integer
      Dim c As Char
 
      length = myString.Length - 1
 
      For i = 0 To length
         If i > length Then
            Exit For
         End If
         c = myString(i)
 
         If myString.IndexOf(c, i + 1) > -1 Then
            myString = myString.Remove(i, 1)
         End If
 
         length = myString.Length - 1
      Next
 
    ' Will result with myString = "helo"

thats in one string. has nothing to do with arrays or lists.

[surya]

Many thanks for your prompt response passero;

I am getting an error, when I use the length attribute; can you please have a look..

Dim Load_String As String = ""
        Dim ArrLoadCases As New List(Of Double)

        ArrLoadCases.Add(MaxVal_PS_BR_LoadCombo)
        ArrLoadCases.Add(MaxVal_PT_CR_LoadCombo)
        ArrLoadCases.Add(MaxVal_PT_TR_LoadCombo)
        ArrLoadCases.Add(MaxVal_AB_TR_LoadCombo)
        ArrLoadCases.Add(MaxVal_AB_CR_LoadCombo)
        ArrLoadCases.Add(MaxVal_AB_CbR_LoadCombo)
        ArrLoadCases.Add(Maxval_AB_ER_LoadCombo)

        ArrLoadCases.Sort()

Dim ArrLoadCases_len As Integer
ArrLoadCases_len = ArrLoadCases.length-1

I am getting an error length' is not a member of 'System.Collections.Generic.List(Of Double)'

Can you please have a look.

Thanks

[surya]

Following temp values can be used for the variables below:

MaxVal_PS_BR_LoadCombo  = 0.50
MaxVal_PT_CR_LoadCombo = 0.75
MaxVal_PT_TR_LoadCombo= 0.75
MaxVal_AB_TR_LoadCombo = 0.45
MaxVal_AB_CR_LoadCombo = 0.65
MaxVal_AB_CbR_LoadCombo = 0.95
Maxval_AB_ER_LoadCombo = 0.91

When using a List(Of Double) the method to get the length of items is .Count instead of .Length
ArrayList / Lists use Count, Array's, strings etc, use Length
