When I running a loop: For Each File As System.io.FileI nfo In FileInfo
Is there a way to tell which file number (index) I'm currently on?
Actually I'd like the ability to skip to a particular index--either
forward or back. It'd be nice to be able to set the index back or
forward with a command button perhaps and the loop just move to that
position and continue forward from there.
I'm specifically interested in doing this in the for each loop.

I am curious why you are not using a 'For...To' loop.

Curiosity is a good thing. Right? I think so. Initially there was no
need for the functionality I'm requesting now and For Each is IMHO
specifically made for looping through collections/arrays so I used it.
So, why don't I change to "For To" etc now? Well, I will if I have to.
I am just curious if I could do this in For Each.
Hope someone knows.

I would say it has been introduced to simplify looping through a collection
or array when index-based access is not important. Obviously the latter is
important in the case you described...

Cj,
A for each loop will only work forwards. You will need to use a for
next loop.

Hi cj,
Thanks for posting!
As Ken and Herfried mentioned, the "For Each" statement is not like the
"For" loop statement. Since "For Each" statement is only working forward,
there is no need to supply the functionalilty of the index. In this
scenario, I suggest you use the "For" loop statement instead of. I
appreciate your understanding.

Um, "IndexOf" function perhaps? Arrays have this as do all the collections
AFAIK.
Though I would agree with what the others recommed as IndexOf would probably
slow down your loop and is sorta dumb to use if you can just change your
look to For x.. To.

The Proper way to code this would be to use a a Do Loop and control the
increment manually.
Do Until whatever_condit ion
'do whatever work on
'fileInfo(i)
If whatever Then
i += 1
Else whatever2 then
i -= 3
...
End If
Loop

Yes there is, however very inefficient to use, and because of the code bad
to maintain, so probably only used by bad developpers who want to obfuscate
there programs direct for everybody. http://msdn2.microsoft.com/system.co...numerator.aspx
The For Next Index gives all the information direct.
I hope this helps,

Brrrrrrrrrrrrrr rr, proper for who, an assembler programmer, who learned less

If you want to visit each item in an Array, you have two alternatives:
Use a For Each..Next loop, using a Variant to retrieve each value in turn.
Use a For...Next loop, looping from the Lower Bound to the Upper Bound of the Array.
For Each...Next seems simpler because you need not worry about retrieving the Lower and Upper Bounds- the loop takes care of that for you.
