I am trying to get this code to read from two textfiles and display them, but I am not getting anything in return.






Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpen.Click
Dim eNumber As String
Dim eName As String
Dim eAddress As String
Dim eSSN As String

Dim pNumber As String
Dim pFICA As Double
Dim pGross As Double
Dim pNet As Double
Dim pDate As Date
Dim pHolding As Double

Dim temp1 As Double = 0.0
Dim temp2 As Double = 0.0
Dim temp3 As Double = 0.0
Dim temp4 As Double = 0.0

Dim sEmployee As String()
Dim sPayroll As String()
Dim pEmployee As String
Dim pPayroll As String

Dim objStreamReader As System.IO.StreamReader
Dim objStreamReader2 As System.IO.StreamReader

objStreamReader = New System.IO.StreamReader("C:\Employee.txt")
objStreamReader2 = New System.IO.StreamReader("C:\Payroll.txt")

pEmployee = objStreamReader.ReadLine()
pPayroll = objStreamReader2.ReadLine()



Do While objStreamReader.ReadLine = "***"
With sEmployee
eNumber = sEmployee(0)
eName = sEmployee(1)
eAddress = sEmployee(2)
eSSN = sEmployee(3)
End With
Loop


Do While objStreamReader2.ReadLine = "***"
With sPayroll
pNumber = sPayroll(0)
pDate = System.Convert.ToDateTime(sPayroll(1))
pGross = System.Convert.ToDouble(sPayroll(2))
temp1 += pGross
pHolding = System.Convert.ToDouble(sPayroll(3))
temp2 += pHolding
pFICA = System.Convert.ToDouble(sPayroll(4))
temp3 += pFICA
pNet = System.Convert.ToDouble(sPayroll(5))
temp4 += pNet
End With
Loop

txtName.Text = eName
txtAdd.Text = eAddress
txtSSN.Text = eSSN

lbxDate.Text = pDate
lbxGross.Text = pGross
lbxHolding.Text = pHolding
lbxFICA.Text = pFICA
lbxNet.Text = pNet

txtGross.Text = temp1
txtHolding.Text = temp2
txtFICA.Text = temp3
txtNet.Text = temp4



End Sub
 
what is the
Visual Basic: 
 Do While objStreamReader.ReadLine = "***"
With sEmployee
eNumber = sEmployee(0)
eName = sEmployee(1)
eAddress = sEmployee(2)
eSSN = sEmployee(3)
End With
Loop
bit supposed to be doing? you really should be reading into a variable otherwise it will just throw away the line it has read. Also you do not appear to be assigning anything to sEmployee either.
 
I changed some of it now how do I make a stucture.
