Need help with Directories

VB Code:

Public Function FileFinder(WatchDir As String) As String
'this function will find the file, if it does not find the file
'that means that it is correct, they have never sent us this file
'before
Dim FileFinding As String
Dim count As Integer
Dim counts As String
Dim result As Long
Dim string2 As String
Dim CaptionValue As Integer
Dim Preferences As String
Dim FileToDelete As String
Dim DeleteMe As Boolean
 
count = 0
 
FileFinding = Dir(WatchDir) 'Where to look for.
Do Until FileFinding = ""
 
    count = count + 1
    FileName = FileFinding
 
    If PreferencesDelimitor <> "" Then
        string2 = PreferencesDelimitor
        result = AmtInStr(FileName, string2)
        Preferences = PreferencesFileFormat - 1
        If result <> Preferences Then
            CaptionValue = 2
            StatusCaptionCase (CaptionValue)
            MoveFileTemp (FileName)
        End If
    Else
        MsgBox ("You MUST choose a Delimitor and File Format")
        Combo1.SetFocus
    End If
    
    FileFinding = Dir 'this is where error occurs
    
    If result = Preferences Then
        MoveFiles (FileName)
        FileToDelete = FileName
        DeleteMe = True
    End If
    
    If DeleteMe = True Then
        DeleteFileName (FileToDelete)
        DeleteMe = False
    End If
Loop
 
counts = CStr(count)
FileFinder = counts
End Function

I have the above function. It works, almost, when the file it is searching for is found it does what it is supposed to do until it reaches the end of the directory list and then it comes back with this error: Run-Time error '5': Invalid procedure call or argument. If it does not find the file then everything works fine. It stops working on FileFinding = Dir.

Any suggestions??

If you just call the Dir function without specifying a search mask -- for instance "*.*" -- the first time, then you get an error.

Try this:

Code:

---

Private Sub Form_Load()

  Dim a As String
  a = Dir
 
End Sub

---

What happens?

Yes... you get that same error: Run-time Error 5. This suggests to me that your program somehow resets the Dir function. Maybe one of those other functions you call in the loop are using calls to Dir. If that is the case, maybe that is your problem.

I don't think so, but let me check.

Thanks that is the problem.

Nope that was not it, still getting the same error

hmm, Are you using any API calls or anything funny like that?

no. It was working fine this morning and then I added the delete calls and ever since then it has not worked.

Hmm, that sounds really weird. I have not had that problem ever. But listen, can you post the code in the DeleteFileName function? I think there is something in there that messes up your code.

Sure, here it is.

VB Code:

Private Sub DeleteFileName(DeletedFile As String)
Dim FilePath As String
 
FilePath = GetFiles & DeletedFile
Kill FilePath
 
End Sub

Here is the AmountInStr Function:

VB Code:

Public Function AmtInStr(String1 As String, string2 As String) As Long 
', string3 As String, string4 As String
'this function counts the number of "." or "_" or "-" in the file name
'this is to know which company the file belongs to
 
    Dim Loop1 As Long, Amount As Integer
    Amount% = 0
 
    For Loop1& = 1 To Len(String1$)
        If InStr(Loop1&, String1$, string2$) <> 0 Then
            Loop1& = InStr(Loop1&, String1$, string2$)
            Amount% = Amount% + 1
        End If
 
    DoEvents
    Next Loop1&
    AmtInStr& = Amount%
End Function

I have also included MoveFile and MoveFileTemp:

VB Code:

Public Function MoveFiles(MoveFileName As String)
'this is the function that is going to do all of the work
'this function will take the filename that has come in and
'find it's directory using the explore function, if a directory
'is not found then one will be created
'it will then try to find the filename of the file that it is
'looking for, if one is found then this will generate and error
'if no file is found the the filename will be moved and success has
'been made
Dim result As String
Dim count As Integer
Dim answer As Integer
Dim FilePath As String
Dim NewFilePath As String
Dim AlreadyThere As String
Dim ActionValue As Integer
Dim CaptionValue As Integer
   
FilePath = GetFiles & MoveFileName
NewFilePath = MoveLocation & MoveFileName
CaptionValue = 2
StatusCaptionCase (CaptionValue)
 
If MoveFileName = "" Then
    result = FileFinder(GetFiles)
    count = CInt(result)
    count = count - 1
    FileCopy FilePath, NewFilePath
    answer = 1
Else
    'FileCopy FilePath, NewFilePath
    'if there is this file in the directory already then
    'raise and error and do not move the file
    'need to create the new folder name, which is the opp number
    'which is the first set of numbers before the first deliminitor
    SaveFile (MoveFileName)
    answer = 1
 
    ActionValue = answer
    If ActionValue = 3 Or ActionValue = 4 Then
        CaptionValue = 3
        StatusCaptionCase (CaptionValue)
 
    Else
        CaptionValue = 0
        StatusCaptionCase (CaptionValue)
 
    End If
    'write to the lstReport what was done
    'example "Moved file from here to there
    ActionCase (ActionValue)
    lstFile.AddItem FileName
End If
 
End Function
 
Public Function MoveFileTemp(MoveToTempFileName As String)
Dim result As String
Dim count As Integer
Dim answer As Integer
Dim FilePath As String
Dim NewFilePath As String
Dim AlreadyThere As String
Dim ActionValue As Integer
Dim CaptionValue As Integer
   
FilePath = GetFiles & MoveToTempFileName
NewFilePath = MoveTempLocation & MoveToTempFileName
CaptionValue = 2
StatusCaptionCase (CaptionValue)
 
If MoveToTempFileName = "" Then
    result = FileFinder(GetFiles)
    count = CInt(result)
    count = count - 1
    FileCopy FilePath, NewFilePath
    answer = 1
Else
    FileCopy FilePath, NewFilePath
    'if there is this file in the directory already then
    'raise and error and do not move the file
    answer = 5
    ActionValue = answer
    If ActionValue = 3 Or ActionValue = 4 Then
        CaptionValue = 3
        StatusCaptionCase (CaptionValue)
 
    Else
        CaptionValue = 0
        StatusCaptionCase (CaptionValue)
 
    End If
    'write to the lstReport what was done
    'example "Moved file from here to there
    ActionCase (ActionValue)
    lstError.AddItem FileName
End If
 
End Function

Hi,
It happen to me the same think while my program in the loop for wating to any file come to the directory to do some process with it, which i work around it by puting another if statment
if oldfilename <> "" then
do wait time
end if
i think some time the cpu is fast which it do 2 process in the same time..looking at the file even no file and doing other function. which indecate the file in use or lock or even not there.
bye
