Array across classes

Hi Guys,

I am writting a program and have a got a bit stuck. Hope you can help, When the program starts, I call LoadData from within the forms load handle.

This inserts data from a flat file into an array. Its a bit of a bodge job but it does what it needs too :)

What I am trying to do now is call the get method for Fullname to pull the information from "ClientData(i)(0)" with i being the record information..

Code:

---

Public Class DBSystem

    Public i As Integer

    Public Sub LoadData()
        'DBPath = String containing full path to same dir as where directory + file ext.
        'DBAval = If string = nothing then create file
        Dim DBPath As String
        DBPath = CurDir() + "\database.txt"

        If (System.IO.File.Exists(DBPath) = False) Then 'No? then create
            My.Computer.FileSystem.WriteAllText(DBPath, "", True) 'Bodge Job to get around File in use/IOException Error
        Else
            Dim DBRawInput As String 'Load Data into String
            DBRawInput = My.Computer.FileSystem.ReadAllText(DBPath)

            Dim arraysize As String() = IO.File.ReadAllLines(DBPath)
            Dim ClientData(arraysize.Length - 1)() As String 'Two-Dimentional Array, 9 fields required so put as 8.. 0 to 8 = 9

            Dim TempArray As New ArrayList(DBRawInput.Split(","c)) 'Split String into one large array

            Dim insdatloop As Integer
            Dim fullnamenl As String
            i = 0
            insdatloop = 0

            While (i < arraysize.Length) 'Loop for how many lines are within DB

                fullnamenl = TempArray(insdatloop) 'Because new Record starts on fresh line, remove line from Array record.
                fullnamenl = Replace(fullnamenl, Environment.NewLine, "")

                ClientData(i) = New String() {fullnamenl, TempArray(insdatloop + 1), TempArray(insdatloop + 2), TempArray(insdatloop + 3), TempArray(insdatloop + 4), TempArray(insdatloop + 5), TempArray(insdatloop + 6), TempArray(insdatloop + 7), TempArray(insdatloop + 8)}
                'Full Name, House Number, Address 1,  County, PostCode, Phone, Email, Job Title, Salary
                'ClientData(i) = New String() {"", "", "", "", "", "", "", "", ""}

                insdatloop = insdatloop + 9
                'MsgBox(fullname, MsgBoxStyle.MsgBoxHelp) 'Testing Data/Data Debug
                i = i + 1 'Add 1 so loop continues to next level in the multidimentional array

            End While
        End If

    End Sub

    Public Property FullName() As String
        Get
            FullName = ClientData(i)(0)
        End Get
        Set(ByVal value As String)
        End Set
    End Property


End Class

Im pulling this information by using

Code:

---

DBSystem1.i = "0"
        txtname.Text = DBSystem1.FullName

---

Under a button click. Unfortunately I am getting the error that ClientData is not declared in:

Code:

---

Public Property FullName() As String
        Get
            FullName = ClientData(i)(0)
        End Get
        Set(ByVal value As String)
        End Set
    End Property

---

How can I get it to work as I need to do this for a number of variables within the class.

Hope you can help,

-Chris

You might get more help in the .NET forum - this is VB6 but your code is .NET

You need to instantiate the class

Code:

---

Dim K as New DBsystem
'  K.Fullname

---

NP, If a mod would move it, it would be greatly appreciated.

The class is already instantiated in the class for the form.

moved.

try:
