bounding data to mschart so i can return non-data point-values - vb.net

I'm trying to build a chart composed of up-to-100% stacked columns, each with 4 series and, once built, upon hovering upon the series, return all bound data (in this case, user names)
I'm very close to what i want, but the tooltip is showing only the sums, which is expected, but i dont know how to proceed. If there's another way that passes over the hover, like clicking and, in the click, I recognize the series and all those that are there, that would help immensely too
What I Have right now
What I Want
After looking it up, i built the chart this way:
(right now its a code nightmare, but i will methodify everything properly later)

If I understand correctly, you are trying to show a tooltip (when hovering the cursor over one colored 'block' in the chart) that shows information about the data that makes up the point.
The problem is that each 'block' is only a single X and Y value. For example: The DataPoint behind the tooltip that shows 'Pessoas = 392' is actually just a simple DataPoint (Series-S X=5 Y=392) with no additional information.
To show a tooltip the way you want each one will have to be pre-set, like this:
point.ToolTip = "User1 in the series\nUser2 in the series\n..."

I have a problem with the first If statement aktivmarkering=1, goes directly to the 'Else' even though if statements is true.
First time code is run, aktivmarkering is = 0, and therefore it obviously goes to 'Else', but after that one has ben run AktivMarkering is = 1, and first if should be executed. I don't see why not - anyone whos able to help?
Thanks.

fastest way to create a bitmap from a large List of items

I am currently creating a list of a class item
Public glstBeamsList As New List(Of BEAMLAYOUT)
Public Class BEAMLAYOUT
Public sourceLocation(2) As Double
Public pointEastingNorthingDepth As New List(Of Double())
End Class
This class list items can have up to 256 points in it with 3 items in the array.
my issue is that the glstBeamsList is continuously being added to and the routine I have reading thru the list to draw the points to a bitmap and display on screen takes a very long time once the list gets large.
here is the code I am using any help is appreciated.
Dim Eastlimit, WestLimit, NorthLimit, SouthLimit As Double
Eastlimit = dblSourceLocationEastings + (gintPlanWidth / 2)
WestLimit = dblSourceLocationEastings - (gintPlanWidth / 2)
NorthLimit = dblSourceLocationNorthings + (gintPlanHeight / 2)

glstBeamsList(i).sourceLocation(1) = 0 Then GoTo nextPoint
For ii = 0 To glstBeamsList(i).pointEastingNorthingDepth.Count - 1
Dim point() = glstBeamsList(i).pointEastingNorthingDepth(ii)
If point(0) < Eastlimit Then
If point(0) > WestLimit Then
If point(1) < NorthLimit Then
If point(1) > SouthLimit Then
Dim x, y As Double
If point(0) < glstBeamsList(i).sourceLocation(0) Then x = point(0) - glstBeamsList(i).sourceLocation(0)
If point(0) > glstBeamsList(i).sourceLocation(0) Then x = glstBeamsList(i).sourceLocation(0) - point(0)
If point(1) < glstBeamsList(i).sourceLocation(1) Then y = point(1) - glstBeamsList(i).sourceLocation(1)
If point(1) > glstBeamsList(i).sourceLocation(1) Then y = glstBeamsList(i).sourceLocation(1) - point(1)
Dim clrPointColor As New Color
Select Case point(2)
Case -10 To 0
clrPointColor = Color.Red
Case -20 To -11

In Form2, change your declaration from
Dim sandl(99) As Integer
to
Public sandl(99) As Integer
This would allow Form3 to access your integer array
Rename your Validate method to something else, like ValidateTextBoxes, or if you intend to overload the base.Validate, then declare as
Private Overloads Function Validate

Last digit(d9) must be: 0 or 9
9xd1+8xd2+7xd3+6xd4+5xd5+4xd6+3xd7+2xd8+d9 mod 11 = 0
I can "validate" the key, but how can I generate more of this, knowing the conditions for it to be right?
How can I generate 9 different integers from 0 to 9 and check them under this formula?
Thanks for helping!
Generate the first 7 digits randomly, calculating the formula for those digits.
Set the 9th digit's value to 9, and add it to the formula.
Calculate a value for the 8th digit based on the mod of the result of the formula that causes the result of the formula to be mod 11 = 0.
For the exception case where attempting to do this causes mod 11 = 9, set the 9th digit to 0.
Implementation:
Private randGen As New Random()
Function GenNum() As Integer
Dim digits(0 To 8) As Integer
GenNum = 0
Dim checkSum As Integer
digits(0) = randGen.Next(6) + 1
If digits(0) >= 3 Then digits(0) += 2
If digits(0) >= 7 Then digits(0) += 1
checkSum += digits(0) * 9
For d As Integer = 1 To 6
digits(d) = randGen.Next(10)
checkSum += digits(d) * (9 - d)
Next
digits(8) = 9
checkSum += digits(8)
If (checkSum Mod 11) Mod 2 = 1 Then
digits(7) = (11 - (checkSum Mod 11)) \ 2
Else
digits(7) = ((12 - (checkSum Mod 11)) \ 2 + 4) Mod 10
End If
checkSum += digits(7) * 2
If checkSum Mod 11 = 9 Then digits(8) = 0
Dim pow10 As Integer = 1
For d As Integer = 8 To 0 Step -1
GenNum += pow10 * digits(d)
pow10 *= 10
Next
End Function
I can help you to generate integers from 0 to 9.
here is how your form should look like:
and here is the code:
Public Class Form1
Dim NumRandom As Random = New Random
Dim X, Y, Z As Integer
Private Sub GenerateBUT_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GenerateBUT.Click
Dim a(9), i, j, RN As Integer
Dim flag As Boolean
flag = False
i = 1
a(j) = 1
Do While i <= 9
Randomize()
RN = CInt(Int(9 * Rnd()) + 1)
For j = 1 To i
If (a(j)) = RN Then
flag = True
Exit For
End If
Next
If flag = True Then
flag = False
Else
a(i) = RN
i = i + 1S
End If
Loop
Label1.Text = a(1)
Label2.Text = a(2)
Label3.Text = a(3)
Label4.Text = a(4)
Label5.Text = a(5)
Label6.Text = a(6)
Label7.Text = a(7)
Label8.Text = a(8)
Label9.Text = a(9)
Z = Label4.Text
Y = Label5.Text
X = Z + Y
X = X - Label3.Text
If X > 1 And X < 10 Then
X = NumRandom.Next(1, 7)
If X = 1 Then
Label1.Text = "0"
ElseIf X = 2 Then
Label2.Text = "0"
ElseIf X = 3 Then
Label3.Text = "0"
ElseIf X = 4 Then
Label4.Text = "0"
ElseIf X = 5 Then
Label5.Text = "0"
ElseIf X = 6 Then
Label6.Text = "0"
ElseIf X = 7 Then
Label7.Text = "0"
End If
End If
End Sub
End Class

taking average of 10 sample in vb2010

I have used below code to find average of 10 sample . But during first time it take sample and do the averaging . during next cycle counter not become Zero.and text box not updating
Static counter As Integer = 0
DIm average_sum As Double = 0
If counter < 10 Then
counter = counter + 1
Count_val.Text = counter
Dim array(10) As Double
For value As Integer = 0 To counter
array(counter) = k
average_sum = average_sum + array(counter)
Next
If counter = 10 Then
average_sum = average_sum / array.Count
System.Threading.Thread.Sleep(250)
Array_count.Text = average_sum
End If
If counter > 10 Then
average_sum = 0
counter = 0
End If
End If
If Avg_count < 10 Then
Dim array(10) As Double
For value As Double = 0 To Avg_count
array(Avg_count) = k
average_sum = average_sum + array(Avg_count)
Avg_count = Avg_count + 1
Next
If Avg_count = 10 Then
average_sum = average_sum / Avg_count
System.Threading.Thread.Sleep(250)
Average.Text = average_sum
Avg_count = 0
End If
End If
Here count value setting properly . But after 2 to3 cycle Average will done earlier itself same thing i writen in excel to compare averages but not matching with average and excel sheet data
Below is excel sheet code.Both code are in timer1 block.
If counter < 10 Then
'counter = 0
'average_sum = 0
Dim headerText = ""
Dim csvFile As String = IO.Path.Combine(My.Application.Info.DirectoryPath, "Current.csv")
If Not IO.File.Exists((csvFile)) Then
headerText = "Date,TIME ,Current, "
End If
Using outFile = My.Computer.FileSystem.OpenTextFileWriter(csvFile, True)
If headerText.Length > 0 Then
outFile.WriteLine(headerText)
End If
Dim date1 As String = "25-10-2014"
Dim time1 As String = TimeOfDay()
Dim x As String = date1 + "," + time1 + "," + distance
outFile.Write(x)
End Using
End If
If counter > 10 Then
counter = 0
End If
