Count Items in file using VB - vbscript

Question

Kind of new to VBS. I'm trying to count the fields in the file and have this code.
Col()
Function Col()
Const FSpec = "C:\test.txt"
Const del = ","
dim fs : Set fs = CreateObject("Scripting.FileSystemObject")
dim f : Set f = fs.OpenTextFile(FSpec, 1)
Dim L, C
Do Until f.AtEndOfStream
L = f.ReadLine()
C = UBound(Split(L, del))
C = C +1
WScript.Echo "Items:", C
Loop
f.Close
End Function
It works however, I don't want to count the delim inside " ".
Here's file content:
1,"2,999",3
So basically, I'm getting 4 items for now but I wanted to get 3. Kind of stuck here.

Answer 1

For an example of my second suggestion, a very simple example could be something like this. Not saying it is perfect, but it illustrates the idea:
Dim WeAreInsideQuotes 'global flag
Function RemoveQuotedCommas(ByVal line)
Dim i
Dim result
Dim current
For i = 1 To Len(line)
current = Mid(line, i, 1) 'examine character
'check if we encountered a quote
If current = Chr(34) Then
WeAreInsideQuotes = Not WeAreInsideQuotes 'toggle flag
End If
'process the character
If Not (current = Chr(44) And WeAreInsideQuotes) Then 'skip if comma and insode quotes
result = result & current
End If
Next
RemoveQuotedCommas = result
End Function
