For various reasons, I'm stuck in Access 97 and need to get only the path part of a full pathname.
For example, the name
c:\whatever dir\another dir\stuff.mdb
should become
c:\whatever dir\another dir\
This site has some suggestions on how to do it: http://www.ammara.com/access_image_faq/parse_path_filename.html
But they seem rather hideous. There must be a better way, right?
This question is related to
vba
ms-access
excel
ms-access-97
You can do something simple like: Left(path, InStrRev(path, "\"))
Example:
Function GetDirectory(path)
GetDirectory = Left(path, InStrRev(path, Application.PathSeparator))
End Function
Try this function:
Function FolderPath(FilePath As String) As String
'--------------------------------------------------
'Returns the folder path form the file path.
'Written by: Christos Samaras
'Date: 06/11/2013
'--------------------------------------------------
Dim FileName As String
With WorksheetFunction
FileName = Mid(FilePath, .Find("*", .Substitute(FilePath, "\", "*", Len(FilePath) - _
Len(.Substitute(FilePath, "\", "")))) + 1, Len(FilePath))
End With
FolderPath = Left(FilePath, Len(FilePath) - Len(FileName) - 1)
End Function
If you don't want to remove the last backslash "\" at the end of the folder's path, change the last line with this:
FolderPath = Left(FilePath, Len(FilePath) - Len(FileName))
Example:
FolderPath("C:\Users\Christos\Desktop\LAT Analysers Signal Correction\1\TP 14_03_2013_5.csv")
gives:
C:\Users\Christos\Desktop\LAT Analysers Signal Correction\1
or
C:\Users\Christos\Desktop\LAT Analysers Signal Correction\1\
in the second case (note that there is a backslash at the end).
I hope it helps...
If you are confident in your input parameters, you can use this single line of code which uses the native Split and Join functions and Excel native Application.pathSeparator.
Split(Join(Split(strPath, "."), Application.pathSeparator), Application.pathSeparator)
If you want a more extensive function, the code below is tested in Windows and should also work on Mac (though not tested). Be sure to also copy the supporting function GetPathSeparator, or modify the code to use Application.pathSeparator. Note, this is a first draft; I should really refactor it to be more concise.

If you're just needing the path of the MDB currently open in the Access UI, I'd suggest writing a function that parses CurrentDB.Name and then stores the result in a Static variable inside the function. Something like this:
Public Function CurrentPath() As String
Dim strCurrentDBName As String
Static strPath As String
Dim i As Integer
If Len(strPath) = 0 Then
strCurrentDBName = CurrentDb.Name
For i = Len(strCurrentDBName) To 1 Step -1
If Mid(strCurrentDBName, i, 1) = "\" Then
strPath = Left(strCurrentDBName, i)
Exit For
End If
Next
End If
CurrentPath = strPath
End Function
This has the advantage that it only loops through the name one time.
Of course, it only works with the file that's open in the user interface.
Another way to write this would be to use the functions provided at the link inside the function above, thus:
Public Function CurrentPath() As String
Static strPath As String
If Len(strPath) = 0 Then
strPath = FolderFromPath(CurrentDB.Name)
End If
CurrentPath = strPath
End Function
This makes retrieving the current path very efficient while utilizing code that can be used for finding the path for any filename/path.
You can do something simple like: Left(path, InStrRev(path, "\"))
Example:
Function GetDirectory(path)
GetDirectory = Left(path, InStrRev(path, Application.PathSeparator))
End Function
Use these codes and enjoy it.
Public Function GetDirectoryName(ByVal source As String) As String()
Dim fso, oFolder, oSubfolder, oFile, queue As Collection
Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection
Dim source_file() As String
Dim i As Integer
queue.Add fso.GetFolder(source) 'obviously replace
Do While queue.Count > 0
Set oFolder = queue(1)
queue.Remove 1 'dequeue
'...insert any folder processing code here...
For Each oSubfolder In oFolder.SubFolders
queue.Add oSubfolder 'enqueue
Next oSubfolder
For Each oFile In oFolder.Files
'...insert any file processing code here...
'Debug.Print oFile
i = i + 1
ReDim Preserve source_file(i)
source_file(i) = oFile
Next oFile
Loop
GetDirectoryName = source_file
End Function
And here you can call function:
Sub test()
Dim s
For Each s In GetDirectoryName("C:\New folder")
Debug.Print s
Next
End Sub
vFilename="C:\Informes\Indicadores\Program\Ind_Cont_PRv.txt"
vDirFile = Replace(vFilename, Dir(vFileName, vbDirectory), "")
' Result=C:\Informes\Indicadores_Contraloria\Programa\Versiones anteriores\
left(currentdb.Name,instr(1,currentdb.Name,dir(currentdb.Name))-1)
The Dir function will return only the file portion of the full path. Currentdb.Name is used here, but it could be any full path string.
I always used the FileSystemObject for this sort of thing. Here's a little wrapper function I used. Be sure to reference the Microsoft Scripting Runtime.
Function StripFilename(sPathFile As String) As String
'given a full path and file, strip the filename off the end and return the path
Dim filesystem As New FileSystemObject
StripFilename = filesystem.GetParentFolderName(sPathFile) & "\"
Exit Function
End Function
This seems to work. The above doesn't in Excel 2010.
Function StripFilename(sPathFile As String) As String
'given a full path and file, strip the filename off the end and return the path
Dim filesystem As Object
Set filesystem = CreateObject("Scripting.FilesystemObject")
StripFilename = filesystem.GetParentFolderName(sPathFile) & "\"
Exit Function
End Function
Try this function:
Function FolderPath(FilePath As String) As String
'--------------------------------------------------
'Returns the folder path form the file path.
'Written by: Christos Samaras
'Date: 06/11/2013
'--------------------------------------------------
Dim FileName As String
With WorksheetFunction
FileName = Mid(FilePath, .Find("*", .Substitute(FilePath, "\", "*", Len(FilePath) - _
Len(.Substitute(FilePath, "\", "")))) + 1, Len(FilePath))
End With
FolderPath = Left(FilePath, Len(FilePath) - Len(FileName) - 1)
End Function
If you don't want to remove the last backslash "\" at the end of the folder's path, change the last line with this:
FolderPath = Left(FilePath, Len(FilePath) - Len(FileName))
Example:
FolderPath("C:\Users\Christos\Desktop\LAT Analysers Signal Correction\1\TP 14_03_2013_5.csv")
gives:
C:\Users\Christos\Desktop\LAT Analysers Signal Correction\1
or
C:\Users\Christos\Desktop\LAT Analysers Signal Correction\1\
in the second case (note that there is a backslash at the end).
I hope it helps...
If you are confident in your input parameters, you can use this single line of code which uses the native Split and Join functions and Excel native Application.pathSeparator.
Split(Join(Split(strPath, "."), Application.pathSeparator), Application.pathSeparator)
If you want a more extensive function, the code below is tested in Windows and should also work on Mac (though not tested). Be sure to also copy the supporting function GetPathSeparator, or modify the code to use Application.pathSeparator. Note, this is a first draft; I should really refactor it to be more concise.

The Dir function will return only the file portion of the full path. Currentdb.Name is used here, but it could be any full path string.
This seems to work. The above doesn't in Excel 2010.

End Function
left(currentdb.Name,instr(1,currentdb.Name,dir(currentdb.Name))-1)
The Dir function will return only the file portion of the full path. Currentdb.Name is used here, but it could be any full path string.
If you're just needing the path of the MDB currently open in the Access UI, I'd suggest writing a function that parses CurrentDB.Name and then stores the result in a Static variable inside the function. Something like this:
Public Function CurrentPath() As String
Dim strCurrentDBName As String
Static strPath As String
Dim i As Integer
If Len(strPath) = 0 Then
strCurrentDBName = CurrentDb.Name
For i = Len(strCurrentDBName) To 1 Step -1
If Mid(strCurrentDBName, i, 1) = "\" Then
strPath = Left(strCurrentDBName, i)
Exit For
End If
Next
End If
CurrentPath = strPath
End Function
This has the advantage that it only loops through the name one time.
Of course, it only works with the file that's open in the user interface.
Another way to write this would be to use the functions provided at the link inside the function above, thus:
Public Function CurrentPath() As String
Static strPath As String
If Len(strPath) = 0 Then
strPath = FolderFromPath(CurrentDB.Name)
End If
CurrentPath = strPath
End Function
This makes retrieving the current path very efficient while utilizing code that can be used for finding the path for any filename/path.
I always used the FileSystemObject for this sort of thing. Here's a little wrapper function I used. Be sure to reference the Microsoft Scripting Runtime.
Function StripFilename(sPathFile As String) As String
'given a full path and file, strip the filename off the end and return the path
Dim filesystem As New FileSystemObject
StripFilename = filesystem.GetParentFolderName(sPathFile) & "\"
Exit Function
End Function
