try this:

Public Function FileCount(ByVal DirectoryName As String) As Long

'E.g. MsgBox FileCount("C:\windows\system")

Dim objFS As New Scripting.FileSystemObject
Dim objFolder As Scripting.Folder

If objFS.FolderExists(DirectoryName) Then
    Set objFolder = objFS.GetFolder(DirectoryName)
    FileCount = objFolder.Files.Count
End If

set objFolder = Nothing
set objFS = Nothing

End Function

tks for your answer, but it's not working. I have an error "user-defined type not defined"

Do you know an API to this?


Tks,

Make a reference to Microsoft Scripting Runtime.

Project | References, then check on Microsoft Scripting Runtime. the function I gave should work.

I got this API from the Internet using ListBox control to count it. this works too

Option Explicit
Private Declare Function SendMessageStr Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String) As Long
Private Sub Command1_Click()
    Dim r As Long
    r = SendMessageStr(List1.hwnd, &H18D, &H20, "C:\windows\*.*")
    MsgBox r + 1
End Sub

wuttrain:

Thank you very much,
the API is working very nice - but every time I "Click" the number in the MsgBox is doubled. Way? Is it because of that the List1 is not cleared? What is the method to clear it?


Tks,
Angel

add this line: List1.Clear

the new click event should look like this:

Private Sub Command1_Click()
Dim r As Long
    List1.Clear
    r = SendMessageStr(List1.hwnd, &H18D, &H20, "C:\windows\*.*")
    MsgBox r + 1
End Sub

this should work for you now.

thanks
