See if a file exists in Visual Basic

Here is a handy little tip (and function) for all you Visual Basic developers out there.  I use this quite often, it’s useful to see if whatever file you are working with or looking for exists before you start trying to access it.  So, here we have a nice little function you can drop into a module and call from anywhere when you need it.

(Need to do the same for a directory? That function is here!)

Check it out:

Public Function fFileExists(ByVal FileName As String) As Boolean
 
        Dim TempAttr As Integer
        On Error GoTo ErrorFileExist
                TempAttr = GetAttr(FileName)
                fFileExists = ((TempAttr And vbDirectory) = 0)
                GoTo ExitFileExist
 
ErrorFileExist:
        fFileExists = False
        Resume ExitFileExist
 
ExitFileExist:
        On Error GoTo 0
 
End Function

There you have it!  Just call it in an IF statement like so:

if fFileExists("c:\temp\myfile.txt") then
  ' Hey, it's there
else
  ' Nope, no file here
end if

It’s just that easy, enjoy!
