I set a program to automatically load values from a temporary file.
However, there is a chance that the specific temporary file "C:\Temp\TU.tmp"
may not exist at all. In that case I want that specific routine to be
skipped. I guess this is a simple

If (that file exists)
Open "C:\Temp\TU.tmp" For Input As #3
etc.......
Else
GoTo
SkipOpeningProcess
End If

and I just define point as "SkipOpeningProcess" and that is fine.
My question is:
What is the command that will trace whether the actual temporary file
exists? If the file does not exist it is perfectly fine to skip this
process as it will be very easy for the traced data to be manually given by
the user.
I assume that's easy but not available in any VB6 book index, ...nor very
easy to find going through pages!
Thank you
J.C.

But don't try to use this within another loop that uses the "dir" command
.... VB only allowes *one*of those "dir" commands to be active at a time.

It is not a simple VB6 command, that's why you haven't found it in the
books. You have to have a procedure like the above to do it. This will
work, though in the long run you should avoid "Dir()" and put the
decision in a FUNCTION where you get the attributes or otherwise access
the file and catch any resulting errors, then return true or false:

If FileExists("c:\temp\tu.tmp") then
'do stuff for no file
End If

'where you create "FileExists()" yourself.

You could add Microsoft Scripting Runtime as a Reference to the project -
this makes available the family of FileSystemObject objects which can do
things like checking whether files and folders exist.

I know some of the chaps on here aren't keen on this, though, and I would be
interested to know why...
