Question about deleting files

Is there any other way to delete a file other then using a FSO or the Kill method?

I have a computer that connectes to remote machines, and deletes files out of a specified folder if it is older then 5 days.  Everything works great, except i receive this error about half of the time:

Runtime error: -2147024832  Description: Method '~' of object '~' failed.

I seem to get it on any number of machines (there is 12 machines that i delete from).  I know it is not a hardware issue (bad hard drive, network issues, etc) because i can delete these files manually via windows (also working remotely, connected to the share).  I have my program dumping all information when it encounters this error, so i know which directory it was trying to delete.  Everything is fine, and i cant figure out what is causing this error.

Any ideas on this, or another way to delete files?

I have found information about it being a problem with windows, but only on windows 2000 or less (fixed after win2k SP1).  All of the PCs have the latest SP on them (all running windows 2000 SP4).  So i dont think that is the issue.

Hi kmorris1186,

found this snippet on the web, uses api:

Private Type SHFILEOPSTRUCT
hwnd As Long
wFunc As Long
pFrom As String
       pTo As String
        fFlags As Integer
      fAnyOperationsAborted As Boolean
        hNameMappings As Long
       lpszProgressTitle As String
End Type

Private Declare Function SHFileOperation Lib "shell32.dll"
        Alias  "SHFileOperationA" (lpFileOp As
        SHFILEOPSTRUCT) As Long

Private Const FO_DELETE = &H3
Private Const FOF_ALLOWUNDO = &H40
'No user interface will be displayed if an error occurs.
Private Const FOF_NOERRORUI = &H400
Private Const FOF_NOCONFIRMATION = &H10 ' Don't prompt the user.

Function KillToRecycleBin(ByVal strFileToDelete As String, _
Optional ByVal PromptUser As Boolean = False) As Long
    Dim lngFlags As Long
    Dim FileOperation As SHFILEOPSTRUCT
   
    lngFlags = FOF_ALLOWUNDO Or FOF_NOERRORUI
    If Not PromptUser Then lngFlags = lngFlags Or FOF_NOCONFIRMATION
   
    With FileOperation
        .wFunc = FO_DELETE
        .pFrom = strFileToDelete
        .fFlags = lngFlags
    End With
    ' Returns 0 if no error
     KillToRecycleBin = SHFileOperation(FileOperation)
End Function

To send a file to the recycle bin use:
KillToRecycleBin "C:\TheFileToDelete.txt"

To prompt the user to send a file to the recycle bin use:
KillToRecycleBin "C:\TheFileToDelete.txt", True

Cheers!

Try This

Paste this in the Form General section
Private Declare Function DeleteFile Lib "kernel32" Alias "DeleteFileA" (ByVal lpFileName As String) As Long

Then call
DeleteFile \\FileName

would that also work with a whole directory?  I am actually deleting images out of folders.  If i delete the images one by one, it is real slow.  If i delete the directory as a whole, it is much faster.

Try this

Public Declare Function RemoveDirectory Lib "kernel32" Alias "RemoveDirectoryA" (ByVal lpPathName As String) As Long

RemoveDirectory \\DirName

i will give it a try! i am still revamping the whole GUI of my program.  Trying to make it more user friendly.  I will get back to in a day or so once i get to the deleting code section.

Thanks! i will try all 3 ways.

Nobody has any ideas about the "Method '~' of object '~' failed" error do ya?

There is some kind of "purge" alternative to "kill"

look it up in MSDN
