Split string using tab,space as delimeter

I read a txt file in a variable and split it in array. Field seperator used in my file is Tab or space (space can be one or more). when i split it by using delimeter TAB then it skips space. pls tell me how can it read space (any number of space)and Tab.

example of txt file

1 0 100 100
2 101 175 75
3 176 250 75
4 251 500 250

in vb 6, SPLIT function does not allow regular expression as a delimiter, but may be you can try this trick

- use regular expression to replace the space(es) or tab(s) to a single character. for example ":".
- next you can use split function to split the result string with delimiter ":".

NOTE : i see that your text example doesn't contain ":" char, so you can do the splitting easily, but if your text file can contain any character (not only number, "+","-",",") you should implement more advance technique.

-Happy coding-

Here is a hack that splits the string base on a space, then splits the splits based on a Tab and puts the whole thing in an array

Code:

---


Private Sub Form_Load()
Dim c()

    s = "1 2" & vbTab & _
        "3 4" & vbTab & _
        "5 6" & vbTab & _
        "7 8" & vbTab & _
        "9 0" & vbTab & "end"
       
    a = Split(s, " ")
    For i = 0 To UBound(a)
        b = Split(a(i), vbTab)
        For j = 0 To UBound(b)
            ReDim Preserve c(k)
            c(k) = b(j)
            k = k + 1
        Next j
    Next i
  ' the split values should now be in the c() array
End Sub

all that redim preserving might make the program wild for memory use or very slow...

I vote the first suggestion to be very good.. replace every occurrence of space with something that is not in the file..

like maybe Chr$(0)

then replace every occurrence of tab, with that same Chr$(0)

Then split the string based on Chr$(0)

I used regular expression for replace space , tab and it is working fine. Code posted by kebo is also working fine. I decided to use first method.
Thanks a lot all of u for given your precious time.
