Hi Jason,
Directory.GetFiles() returns a String array, not a boolean value, so you
can't do it that way.
In my opinion, this method will only return the names of matching files in
the folder, so they *have* to be existing, don't they ? Why would you need
to check if the file exists in this case ?
If you want to check if anything was returned at all, then just use Kerry's
method and check for the Length property of the returned String array.
Dim Dirs As String() = Directory.GetFiles("c:\test", "123-4567*")
If Dirs.Length > 0 then
'Atleast 1 file was found
Else
'No file matching this pattern was found
End if

That works great, but is there a way I can determine if that file first
exists?
CAn I do a ....
If ((Dim dirs As String() = Directory.GetFiles("c:\test", "123-4567*")) <>
true) Then
'File does not exist
or is there a easier way?
Thanks

Retrieve just the file names that begin with the known string:
Dim dirs As String() = Directory.GetFiles("c:\test", "123-4567*")
Then see how many files you got and proceed accordingly:
If dirs.Length = 1 Then
'Display the file name
MsgBox(dirs(0))
ElseIf dirs.Length = 0 Then
MsgBox("Not found")
Else
MsgBox("More than 1 file found")
End If

I need to open a file for reading, but I only know part of it's name.
The file I want to read is in the format of xxx-yyyy-zzz.EXT
The last three digits of the file name are different on each pc, for
example
PC7 has xxx-yyyy-zz1.ext
PC5 has xxx-yyyy-zz2.ext
PC3 has xxx-yyyy-zz8.ext
and so on.
I need to find out if that file exists by using the first 7 seven
digits and if it does exist, then open it up for reading.
The way I do this now is to loop through the folder, and look at the
first
7seven digits using the substing method and if that name equals a
constant
(xxx-yyyy) then I open that file.
It works, but it seems like extra work, plus depending on the number of
files it can eat up alot of time.
Any ideas
