[Jan]

This is my problem:
When i have more than 3 lines of text in de tempArray. Iget the following
message:

An unhandled exception of type 'System.NullReferenceException' occurred in
Allen's Woodshop.exe

Additional information: Object reference not set to an instance of an
object.

The program holds on the line:
'strItem=strTextline(intFormTotal).Split(";")'

I'm completly stuck at the moment, so i hope someone can help out of this
mess. Thankx a lot

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs)

Dim strItem(3), strTempItem(3) As String
Dim myComp, Teller As Integer

counter = 0

For intFormTotal = 0 To strTextline.GetUpperBound(0)

strItem = strTextline(intFormTotal).Split(";")
strTempItem = tempArray(counter).Split(";")

myComp = StrComp(strItem(0), strTempItem(0),CompareMethod.Text)

If myComp = 0 Then
strItem(3) = strTempItem(3)
strTextline(intFormTotal) = Join(strItem, ";")

counter += 1
If tempArray.GetUpperBound(0) = counter Then

Exit For
End If

Else
strItem(3) = strItem(3)
strTextline(intFormTotal) = Join(strItem, ";")

If tempArray.GetUpperBound(0) = counter Then
Exit For
End If

End If
Next

FForm1.lstWoodshop.Items.Clear()
intFormTotal = 0
Do Until intFormTotal = 24
FForm1.lstWoodshop.Items.Add(strTextline(intFormTo tal))
intFormTotal += 1
Loop

End Sub

I can not reproduce it because several variable declarations are missing.

I declared Dim counter, intFormTotal As Integer, but how am I to declare
tempArray and strTextline?

if you declare an array w 3 places (4 if you are starting from 0) it can
only hold 3 things

don't have time to go over it completely but i think this could be the
problem

I have declared them with:
dim tempArray(25) as string
dim strTextline(25) as string

thnx for your attention

There are no strings in the array. The array can hold 26 strings (index 0 to
25) but you don't store strings in the array.
