Hi All,

i was wondering if anyone could assist. i have a form with 2 listbox, that allows user to enter in a directory path that is then populated in to the listbox1. I have a button on the form that i want to be able to press which cycle through the listbox items and checks if the directory exists.

i was thinking it would be something along the lines of :

VB

For Each something In listbox1

if system.io.file.exist(somethinghere2) = false then
      'in second listbox display missing directory
    listbox2.item.add("does not exist " & somethinghere2)
     else
        'if the directory does exist
       'do nothing
end if

   Next

this is for purpose to help me with my job, so i dont have to manually check if users have deleted directories overnite.... im not much of a programmer but any help would be great.

So what's the problem really? Are you having some errors?

And I think you sould use System.IO.Directory.Exists not file

For a simple solution to check if directory is exist just try this simple code

If Dir("yourdirectory") = "" Then
 ' does not exist
End If

Have a shame! It's totally wrong. You need to try code if you want to post an answer.

If you're going to check if a directory exists, you should use

System.IO.Directory.Exists() function which returns True if the directory exists and False otherwise.

If you're going to check if a file exists, you should use

System.IO.File.Exists() function.

If you want to iterate through all files in a directory, you should use

System.IO.Directory.GetFiles(string path)

Check Microsoft's documentation on System.IO.Directory
