I am trying to split a log file and load it into a listview.

The fields in the file are delimited with a tab (vbtab).

I open the file, load the entire line into a string variable, i then attempt to use the split function as follows:

strSplit = Split(strLine, vbTab)

This should split the fields where ever there is a tab! it doesnt work! It splits the fields when there is a tab, but also when there is a ", " (command & space)! why would this happen and how do i fix it??

I have tried to split with chr(9) (tab ascii value) and that doesnt work either!

*******************************
HERE IS MY SUB CODE:

Public Sub LoadLog(Lv As ListView, strFile As String)
    Dim intFileNum As Integer
    Dim strLine As String
    Dim strSplit() As String
    Dim Li As ListItem
   
    intFileNum = FreeFile
    Open strFile For Input As #intFileNum
   
    Do Until EOF(intFileNum)
        Input #intFileNum, strLine
        If strLine = "" Then Exit Do
        strSplit = Split(strLine, vbTab)
       
        Set Li = Lv.ListItems.Add(, , strSplit(0))
        Li.SubItems(1) = strSplit(1)
        Li.SubItems(2) = strSplit(2)
        Li.SubItems(3) = strSplit(3)
        Li.SubItems(4) = strSplit(4)
    Loop
   
    Close #intFileNum
End Sub


Thanks for the help!

Very strange,

well, Try to replace the comma with some other special characters like " ^ ", before spliting with vbTab. and after spliting again Replace ^ with comma before adding to the listview.


btw, can u post the contents of the text.

The following ran fine:

x = "03/24/2002 12:59:47 AM@4.33.208.84@no@Keizer@0204 - Two Cars in Every Garage, and ThreeEye.rm"
z = Replace(x, "@", vbTab)
strSplit = Split(z, vbTab)

One would tend to suspect extra tabs in your input data.

The only problem that i can see is that there is not a real tab character.

Do this:
Create a little file with 2 lines and last one as its contents replacing every "tab" with a "real" one and try again.
I did a test with your code and works OK.

Public Sub LoadLog(Lv As ListView, strFile As String)
   Dim ff As Integer
   Dim strLine As String
   Dim strSplit
   Dim li As ListItem
   
   ff = FreeFile
   Open strFile For Input As #ff
   
   Do Until EOF(ff)
       Line Input #ff, strLine
       If strLine = "" Then Exit Do
       strSplit = Split(strLine, vbTab, , vbBinaryCompare)
       
       Set li = Lv.ListItems.Add(, , strSplit(0))
       Dim i As Integer
       For i = 1 To UBound(strSplit)
        li.ListSubItems.Add i, , strSplit(i)
       Next i
   Loop
   
   Close #ff
End Sub

If your data really is clean, you might avoid Split() and do something like:

i=0
tp=instr(linein,vnTab)
while tp>0
      i=i+1
      field(i)=left(linein,tp-1)
      linein=substr(linein,tp+1)
      tp=instr(linein,vnTab)
      wend
field(i+1)=linein

The question states that
**I am trying to split a log file and load it into a listview**. I suppose there should not be any extra tab.


..and what's wrong with my comment!!!. I had posted almost a similar thing what cookre did.
