Hi All
I need some code to search for a file that could be in any directory or subdirectory. I found the code below and whilst if you tap though it seems to be doing its job but when let loose properly it fails with an error 52 issue. Cut and paste the whole code in to a module and then run the following in the immediate window.
Dim strFile As String
strFile = ListFiles("C:\", "thefilename.ext", True)
I would be truly grateful if anybody could explain why this might be.
Public Function ListFiles(strPath As String, Optional strFileSpec As String, _
Optional bIncludeSubfolders As Boolean, Optional lst As ListBox)
On Error GoTo Err_Handler
'Purpose: List the files in the path.
'Arguments: strPath = the path to search.
' strFileSpec = "*.*" unless you specify differently.
' bIncludeSubfolders: If True, returns results from subdirectories of strPath as well.
' lst: if you pass in a list box, items are added to it. If not, files are listed to immediate window.
' The list box must have its Row Source Type property set to Value List.
'Method: FilDir() adds items to a collection, calling itself recursively for subfolders.
Dim colDirList As New Collection
Dim varItem As Variant
Call FillDir(colDirList, strPath, strFileSpec, bIncludeSubfolders)
'Add the files to a list box if one was passed in. Otherwise list to the Immediate Window.
If lst Is Nothing Then
For Each varItem In colDirList
ListFiles = varItem
Next
Else
For Each varItem In colDirList
lst.AddItem varItem
Next
End If
Exit_Handler:
Exit Function
Err_Handler:
MsgBox "Error " & Err.Number & ": " & Err.Description
Resume Exit_Handler
End Function
Private Function FillDir(colDirList As Collection, ByVal strFolder As String, strFileSpec As String, _
bIncludeSubfolders As Boolean)
'Build up a list of files, and then add add to this list, any additional folders
Dim strTemp As String
Dim colFolders As New Collection
Dim vFolderName As Variant
'Add the files to the folder.
strFolder = TrailingSlash(strFolder)
strTemp = Dir(strFolder & strFileSpec)
Do While strTemp <> vbNullString
colDirList.Add strFolder & strTemp
strTemp = Dir
Loop
If bIncludeSubfolders Then
'Build collection of additional subfolders.
strTemp = Dir(strFolder, vbDirectory)
Do While strTemp <> vbNullString
If (strTemp <> ".") And (strTemp <> "..") Then
If (GetAttr(strFolder & strTemp) And vbDirectory) <> 0& Then
colFolders.Add strTemp
End If
End If
strTemp = Dir
Loop
'Call function recursively for each subfolder.
For Each vFolderName In colFolders
Call FillDir(colDirList, strFolder & TrailingSlash(vFolderName), strFileSpec, True)
Next vFolderName
