Filling an array from a .txt file VB 6.0 - arrays

Question

I'm lost, I try to fill arrays and receive a type mismatch
I'm trying to fill 4 arrays from one file
There is 500 lines in the text document each holding 4 different types of data separated by ","
The .txt file format example --->
pear, apple, grape, orange
apple, pear, orange, grape
ect...
Here is my code:
Private Sub CmdRun_Click()
Dim ticketid(500) As Variant
Dim theatreid(500) As Variant
Dim ticketamount(500) As Variant
Dim paymethod(500) As Variant
Open "C:\Users\Dylaan\Desktop\School Solution\tickets.txt" For Input As #1
Do While Not EOF(1)
Input #1, ticketid(), theatreid(), ticketamount(), paymethod()
lstticketid.AddItem ticketid()
lsttheatreid.AddItem theatreid()
lstticketamount.AddItem ticketamount()
lstmethod.AddItem paymethod()
Exit Do
Loop
Close #1
End Sub
Why?

Answer 1

take a look on this:
Private Sub CmdRun_Click()
Dim ticketid(500) As Variant
Dim theatreid(500) As Variant
Dim ticketamount(500) As Variant
Dim paymethod(500) As Variant
dim ix as integer
Open "C:\Users\Dylaan\Desktop\School Solution\tickets.txt" For Input As #1
ix = 0
Do While Not EOF(1)
Input #1, ticketid(ix), theatreid(ix), ticketamount(ix), paymethod(ix)
lstticketid.AddItem ticketid(ix)
lsttheatreid.AddItem theatreid(ix)
lstticketamount.AddItem ticketamount(ix)
lstmethod.AddItem paymethod(ix)
ix = ix + 1
Loop
Close #1
End Sub
And of course you should consider to use
freefile (to get a filehandle)
and also the possibility that there are MORE records than expected ...

Answer 2

Set fso = CreateObject("Scripting.FileSystemObject")
Set srcfile = fso.GetFile("c:\myfile.txt")
If err.number = 0 then Set TS = srcFile.OpenAsTextStream(1, 0)
Src=ts.readall
Arr1=Split(Src, vbcrlf)
For Each thing in Arr1
Arr2=Split(thing, ",")
For Each thing2 in Arr2
msgbox thing2
Next
Next
This is vbscript but will work in VB6. We are using the split command.

Some comments on your code:
You don't need to declare those arrays as variants, you can declare them as arrays of strings.
As the file is just 500 lines you can read it in at once.
Your real problem is the input command: It can't read in arrays at once.
The same applies to the listbox: You can't add an array at once.
With all that applied have a look at the following test project:
'1 form with:
' 1 command button : name=Command1
' 4 listbox controls : name=List1 name=List2 name=List3 name=List4
Option Explicit
Private Sub Command1_Click()
Dim strData As String
strData = ReadFile("c:\temp\file.txt")
ShowData strData
End Sub
Private Sub Form_Resize()
Dim sngWidth As Single
Dim sngCmdHeight As Single
Dim sngLstWidth As Single, sngLstHeight As Single
sngWidth = ScaleWidth
sngCmdHeight = 315
sngLstHeight = ScaleHeight - sngCmdHeight
sngLstWidth = sngWidth / 4
List1.Move 0, 0, sngLstWidth, sngLstHeight
List2.Move sngLstWidth, 0, sngLstWidth, sngLstHeight
List3.Move 2 * sngLstWidth, 0, sngLstWidth, sngLstHeight
List4.Move 3 * sngLstWidth, 0, sngLstWidth, sngLstHeight
Command1.Move 0, sngLstHeight, sngWidth, sngCmdHeight
End Sub
Private Function ReadFile(strFile As String) As String
Dim intFile As Integer
Dim strData As String
intFile = FreeFile
Open strFile For Input As #intFile
strData = Input(LOF(intFile), #intFile)
Close #intFile
ReadFile = strData
End Function
Private Sub ShowData(strData As String)
Dim lngLine As Long
Dim strLine() As String
Dim strPart() As String
strLine = Split(strData, vbCrLf)
For lngLine = 0 To UBound(strLine)
strPart = Split(strLine(lngLine), ",")
If UBound(strPart) = 3 Then
List1.AddItem strPart(0)
List2.AddItem strPart(1)
List3.AddItem strPart(2)
List4.AddItem strPart(3)
Else
'not the correct number of items
End If
Next lngLine
End Sub
When you click on Command1 it will read in the textfile from c:\temp\file.txt
After that it will split the data to form an array of lines, loop over all lines, split each line into part, and show the parts in the listboxes, if there are exactly 4 parts on a line.
