I have some code that looks for a file; if it doesn't find it I need to exit
my sub because the rest of the sub clears my worksheet and imports new data
from the file. If the code runs without the file present, it clears my sheet
but doesn't have anything to import- which messes up a lot of subsequent
stuff.

Here is the code snippet; the problem is that I've manually placed the file
in the correct directory, but this code still doesn't find it, so it hits
the exit sub.
Any ideas what I'm doing wrong?
Thanks!!

Hello

a quick look at this makes me wonder about the line

On Error GoTo TTINT1NoFile:

Is that a label in your sub? I think better might be to try

On error goto 0 (ie shut off error handling) and see what happens.

I hope that helps.

My apologies- I didn't include the error loop. It is fairly simple (see
below). It isn't throwing that messagebox either, so I'm assuming that no
errors are occuring in the part of the code that would throw it to this
errorhandler. I've also walked through the code with F8 to confirm that it
hits the loop, but doesn't seem to think the file is there (drops to the
original post exit sub statement)
Thanks,
Keith

'Code from original post was at the top of the sub

'misc code to crunch the file, removed here for space

load updated TTINT1 data." & vbCrLf & vbCrLf & _
"TTINT files are removed once they have been processed, so if the TTINT
'upload' has already occured today you may ignore this error.", , "File Not
Found"

Looks like you need to assign a file path to the DataFileLocation variable.
Something like...
Dim DataFileLocation as String
DataFileLocation = "C:\Documents and Settings\Name\My Documents\FileName"

Jim- My apologies, I was trying to cut down on the necessary code posted,
but that isn't a good strategy when others are helping troubleshoot. I have
the path and file set as global variables (I use them in other modules as
well). Here is the whole sub. The source file(s) are produced automatically
and the name/location doesn't change, and I've confirmed that it hasn't
changed in my code. Is there any other reason (recent windows updates,
anything at all?) that might affect whether the VBA can locate the file?
Maybe a lag in server response?

I tried the code at http://www.vbaexpress.com/kb/getarticle.php?kb_id=247 to
see if I could at least confirm that the directory is accessible to VBA;
I've confirmed that I can get a correct count of both the files in that
directory, and specifically the .txt files in that directory. For some
reason, the code below just quit working, and I can't figure out why :(

The good news is that the error occurs only about 20 lines in (marked
in-line), so you don't have to read the whole sub to see what's going on.
I appreciate any suggestions - fixes or additional ideas on what to
troubleshoot.
Best,
Keith

Nevermind, I'm an idiot. I had the path, but due to replicating this code
for two data files with identical format, I append the filename later in the
sub, where is should be at the top. Life is good.

Thanks all,
Keith
