File Exists

In VB6, how do I determine if a given file exists? I think it has something to do with the lenght of the string.

The site doesn''t work. It loads, then the error screen comes up. Can anyone tell me how to determine if a file exists in VB6?

I''m pretty sure you use the function Dir(). You pass it the name of the file you''re looking for, and check the return value. If it is equal to "" then the file doesn''t exist.
Try somthing like this:
Dim file As String
file = "document.txt"
If Dir(file) = "" Then
''The file doesn''t exist
End If
Try somthing like this:
Dim file As String
file = "document.txt"
If Dir(file) = "" Then
''The file doesn''t exist
End If

here's a quick easy way:
you can also get a list of existing files with the dir$() function, and then search this list... but that would take longer to type in, heh heh...
