Program displaying wrong values, what needs to be changed? - vb.net

My program to display employee records works fine other than the face that it displays incorrect values when it comes to pay. What needs to be changed?
Sub AddPlist(month As String, age As String, employeenumberid As Integer, hourlyrateline As Integer)
Dim hoursworkedline As String
Dim normalhoursworked As Integer
Dim overtimerate As String
Dim normalpay As Decimal
Dim overtimepay As Decimal
Dim overtimehoursworked As Integer
Dim grosspay As Decimal
Dim taxrate As Decimal
Dim taxdeducted As Decimal
Dim nideducted As Decimal
Dim netpay As Decimal
Do
Console.Write("Please enter hoursworked: ")
hoursworkedline = Console.ReadLine()
If Not hoursworkedline IsNot Nothing OrElse Not IsNumeric(hoursworkedline) Then Console.Write("hoursworked must be entered!!: ")
Loop While Not hoursworkedline IsNot Nothing OrElse Not IsNumeric(hoursworkedline)
If hoursworkedline > 40 Then
normalhoursworked = 40
overtimerate = hourlyrateline * 0.15
overtimehoursworked = hoursworkedline - 40
normalpay = normalhoursworked * hourlyrateline
overtimepay = overtimehoursworked * overtimerate
grosspay = normalpay + overtimepay
taxrate = If(age < 18, 18, If(age < 60, 25, If(age > 60, 20, Nothing)))
taxdeducted = grosspay * taxrate
nideducted = grosspay * ((grosspay / 100) * 7)
netpay = grosspay - taxdeducted - nideducted
Else
normalhoursworked = hoursworkedline
overtimerate = hourlyrateline * 0.15
overtimehoursworked = 0
normalpay = normalhoursworked * hourlyrateline
overtimepay = 0
grosspay = normalpay + overtimepay
taxrate = If(age < 18, 18, If(age < 60, 25, If(age > 60, 20, Nothing)))
taxdeducted = grosspay * taxrate
nideducted = grosspay * ((grosspay / 100) * 7)
netpay = grosspay - taxdeducted - nideducted
End If

One thing I noticed wrong is you're only paying 15% of the hourly rate for overtime. I think you mean to multiply by 1.5 not .15
Plus you have a lot of duplication in your code consider this:
If hoursworkedline > 40 Then
normalhoursworked = 40
overtimehoursworked = hoursworkedline - 40
Else
normalhoursworked = hoursworkedline
overtimehoursworked = 0
End If
overtimerate = hourlyrateline * 1.5
normalpay = normalhoursworked * hourlyrateline
overtimepay = overtimehoursworked * overtimerate
grosspay = normalpay + overtimepay
'Also your taxrate algorithm doesn't allow for someone exactly 60
taxrate = If(age < 18, 18, If(age < 60, 25, If(age >= 60, 20, Nothing)))
'Another thing your multiplying the grosspay by whole numbers not percentages
taxdeducted = grosspay * (taxrate / 100)
'Not sure what outcome you expect from this but it doesn't look quite right
nideducted = grosspay * ((grosspay / 100) * 7)
netpay = grosspay - taxdeducted - nideducted

Change Number of Categories between Tick-Mark Labels on Chart X-axis

If I have more (or less) data in my Access 2010 graph, I want to decrease (or increase) the number of tick marks on the X-axis. I looked for the right syntax but I couldn't find it.
I did the same for the Y-axis Title and that works fine:
me.Graph1.Object.Axes(2,1).AxisTitles.Caption="g/ml"
For number of tick-marks of the X-axis; I've tried a number of words can not find the right one. It stopped at:
me.Graph.Object.Axes(1,1).Scale.???????? (I want a number of categories = 3 )
Example code from my db for XYScatter chart. xlCategory is for X-axis and xlValue is Y-axis.

Find First and Last Number in a Range of Numbers

Imagine a range of numbers from -133 to +71.
I want to find the first and last numbers in the range that divide by 20: in this case it would be -120 and +60.
I can write a For loop that tests each value and stores the required values:
Dim resultFirst, resultLast As Integer
Dim FirstFound As Boolean = False
For a As Integer = -133 To 71
If a Mod 20 = 0 Then
If FirstFound = False Then
resultFirst = a
FirstFound = True
End If
resultLast = a
End If
Next
but I suspect there is a simpler formula.
You can use Enumerable.Range() and the LINQ-methods Where, Min and Max
Dim resultFirst As Integer
Dim resultLast As Integer
Dim min As Integer = -133
Dim max As Integer = 71
Dim div As Integer = 20
resultFirst = Enumerable.Range(min, max - min + 1).Where(Function(x) x Mod div = 0).Min()
resultLast = Enumerable.Range(min, max - min + 1).Where(Function(x) x Mod div = 0).Max()
Try this one
Dim s As IEnumerable(Of Integer) =
Enumerable.Range(-133, 133 + 72)
Dim minV As Integer = s.AsEnumerable().Where(Function(n) n Mod 20 = 0).Min(Function(n) n)
Dim maxV As Integer = s.AsEnumerable().Where(Function(n) n Mod 20 = 0).Max(Function(n) n)
Console.WriteLine(minV.ToString() & " " & maxV.ToString())
Console.ReadLine()
You can use the following to get the first and last value which is dividable by 20:
Dim fromValue As Integer = -133
Dim first As Integer = (fromValue - (fromValue Mod 20)) + IIf(fromValue > 0 And fromValue Mod 20 <> 0, 20, 0)
Dim toValue As Integer = 71
Dim last As Integer = (toValue - (toValue Mod 20)) - IIf(toValue < 0 And toValue Mod 20 <> 0, 20, 0)
You can also create a function using the above formula:
Private Function GetResult(ByVal fromInt As Integer, ByVal toInt As Integer, ByVal divider As Integer) As Integer()
'set the real from and to value from parameter.
Dim fromValue As Integer = Math.Min(fromInt, toInt)
Dim toValue As Integer = Math.Max(fromInt, toInt)
'get the first and last number dividable by divider between numbers.
Dim first As Integer = (fromValue - (fromValue Mod divider)) + IIf(fromValue > 0 And fromValue Mod divider <> 0, divider, 0)
Dim last As Integer = (toValue - (toValue Mod divider)) - IIf(toValue < 0 And toValue Mod divider <> 0, divider, 0)
If first > toValue Or last < fromValue Then
Return {}
Else
Return {first, last}
End If
End Function
Some test cases for the above function:
GetResult(-133, 71, 20) '0: -120; 1: 60
GetResult(71, -133, 20) '0: -120; 1: 60
GetResult(100, 119, 20) '0: 100; 1: 100
GetResult(-113, -112, 20) 'empty array
GetResult(120, 140, 20) '0: 120; 1: 140

You will need to read the value for intMonths because it is only declared and not assigned.
Assign your intMonths to the TextBox value. Simplify your syntax.

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

losing precision while calculating cost

I've got this program to calculate the cost of sheets of paper. First the prices and bundles are declared and intialized. Then I use if else statements with division and modulos to break down the bundle into charging rates. Although my paper bundle amounts are correctly computed, my total costs are off. Can anyone spot what I'm doing wrong here?
Module Paper
Sub Main()
'declare variables
Dim PaperAmountReq As Double
Dim PricePer_1_Sheet As Double = 0.1
Dim PricePer_100_Sheets As Double = 0.055
Dim PricePer_500_Sheets As Double = 0.04
Dim PricePer_1000_Sheets As Double = 0.03
Dim NumberOfSingles As Double = 0
Dim NumberOf100s As Double = 0
Dim NumberOf500s As Double = 0
Dim Numberof1000s As Double = 0
Dim TotalCost As Double
Console.Write("Enter number of sheets of paper needed: ")
PaperAmountReq = Console.Readline
If PaperAmountReq / 1000 >= 1 Then
Numberof1000s = PaperAmountReq \ 1000
PaperAmountReq = PaperAmountReq Mod 1000
End If
If PaperAmountReq / 500 >= 1 Then
NumberOf500s = PaperAmountReq \ 500
PaperAmountReq = PaperAmountReq Mod 500
End If
If PaperAmountReq / 100 >= 1 Then
Numberof100s = PaperAmountReq \ 100
PaperAmountReq = PaperAmountReq Mod 100
End If
If PaperAmountReq / 1 = PaperAmountReq Then
NumberOfSingles = PaperAmountReq
End If
'TotalCost = (Convert.ToDouble(Numberof1000s) * PricePer_1000_Sheets) + (Convert.ToDouble(NumberOf500s) * PricePer_500_Sheets) + (Convert.ToDouble(Numberof100s) * PricePer_100_Sheets) + (Convert.ToDouble(NumberOfSingles) * PricePer_1_Sheet)
TotalCost = (Numberof1000s * PricePer_1000_Sheets) + (NumberOf500s * PricePer_500_Sheets) + (Numberof100s * PricePer_100_Sheets) + (NumberOfSingles * PricePer_1_Sheet)
Console.WriteLine("Number of 1000 packages: " & Numberof1000s)
Console.WriteLine("Number of 500 packages: " & Numberof500s)
Console.WriteLine("Number of 100 packages: " & Numberof100s)
Console.WriteLine("Number of singles packages: " & NumberOfSingles)
Console.Write("Total Cost: " & TotalCost)
End Sub
End Module
With this:
If PaperAmountReq / 1000 >= 1 Then
Numberof1000s = PaperAmountReq \ 1000
PaperAmountReq = PaperAmountReq Mod 1000
End If
if you have 1500, you are setting Numberof1000s equal to 1 - not 1000. So when you calculate your total cost, your value of (presumably) cost/sheet is being multiplied by 1 instead of 1000.
Either change your equation here
TotalCost = (Numberof1000s * PricePer_1000_Sheets) + (NumberOf500s * PricePer_500_Sheets) + (Numberof100s * PricePer_100_Sheets) + (NumberOfSingles * PricePer_1_Sheet)
to be something like
TotalCost = (Numberof1000s * PricePer_1000_Sheets * 1000) + (NumberOf500s * PricePer_500_Sheets * 500) + (Numberof100s * PricePer_100_Sheets * 100) + (NumberOfSingles * PricePer_1_Sheet * 1)
or adjust the PricePer_XXX_Sheets values to be the equivalent values.
Dim PricePer_1_Sheet As Double = 0.1
Dim PricePer_100_Sheets As Double = 0.055 * 100
Dim PricePer_500_Sheets As Double = 0.04 * 500
Dim PricePer_1000_Sheets As Double = 0.03 * 1000
Well your numberof variables should be integers or maybe bigintegers if not big enough as should PaperAmountReq
Your code seems to be assuming integer division
in these segments
If PaperAmountReq / 500 >= 1 Then
NumberOf500s = PaperAmountReq \ 500
PaperAmountReq = PaperAmountReq Mod 500
End if
in actual fact because you are using doubles, it's doing floating point division.
I'd also recommend that you use decimal instead of double for your price? and Total Cost variables.
Doubles are very precise, but often very inaccurate.
Looks like you need to convert the NumberOfXXXs variables to sheets, rather than bundles.
Your formula at the end uses per-sheet costs with per-bundle numbers. Either update the costs to be per-bundle, or update the bundle numbers to equal the round number of sheets in that bundle:
TotalCost = NumberOf1000s * 1000 * PricePer_1000_Sheets
Dim PricePer_100_Sheets As Double = 0.055
Dim PricePer_500_Sheets As Double = 0.04
Dim PricePer_1000_Sheets As Double = 0.03
should be
Dim PricePer_100_Sheets As Double = 0.055 * 100
Dim PricePer_500_Sheets As Double = 0.04 * 500
Dim PricePer_1000_Sheets As Double = 0.03 * 1000
