[AccessD] A2003:Replacing 'tokens' in a string

The point you're missing is that a routine to parse a string is *part* of a string-handling class.  Get used to the idea of classes Max.  You will be assimilated.

Yes, to make it more flexible and robust it  wouldn't take much more  work
on yours, mine or Keith's  submissions.

But, I would not go  the class route just to parse a string,  which  is the
point I am really making.

Horses for Courses and each to their own.    For me KISS works.

Thanks

Max

Max,

How about that? (To satisfy original request of getting extracted just
AccountNo and InvoiceNo out of the source string.)

Dim s As String
s = "[AccountNo]=1234," + _
    "[InvoiceNo]=1234567," + _
    "[InvoiceDate]=04/01/2010,[Name]=Barry"
    
Debug.Print Val(Mid(s, InStr(s, "[InvoiceNo]") + 12))
Debug.Print Val(Mid(s, InStr(s, "[AccountNo]") + 12))

Yes, it's not "bullet-proof" but if the source string is guaranteed to have
specified format then that simple approach will work well.

Please don't start telling (you will not I expect but others here can I
guess :)) "we all know how "specified formats" can often change" - just
program against the current requirements and wait for the other day and new
requirements to come - that's is the current mainstream trend in agile Test
Driven Development...

We can spend a lot of time discussing what is the probability of the
specified source string format to change, and how to "bullet-proof" the
above lightweight coding(?) approach - should we? - that's not a rhetoric
question, folks - your opinions coming from your experience is wanted and
very welcome...

Thank you :)

Yes John/Drew but why use that horrendous code when you can do the same with
this..

Call
xsplit("[AccountNo]=1234,[InvoiceNo]=1234567,[InvoiceDate]=04/01/2010,[Name]
=Barry")

Function xSplit(str as string)
    Dim arr() As String, i As Integer
    arr = Split(str, ",")
    Debug.Print arr(0), arr(1), arr(2), arr(3) 'Done!
	'if you want the values then this next bit will do that
    For i = 0 To 3
        arr(i) = Mid(arr(i), InStr(arr(i), "=") + 1)
        Debug.Print arr(i),
    Next i
End Function

A person cannot go through life taking the more obtuse form of coding just
so that they may "learn" something new.
It is all about getting the code out.
I am with Stuart on  this.

LOL

Stuart, I think you misunderstand.  We all recommend that you do the minimum
amount of work 
necessary and stay ignorant the rest of your life.  It has worked for me for
all these many years. 
Why in the world would you want to take an opportunity and actually LEARN
something?
