The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Loop through all subfolders and output file names

Zones: Microsoft Excel Spreadsheet Software, Visual Basic Programming

Tags: VB

I wish to search through a directory looking for files that match a preset file name. The following bit of code I have is not doing that, it is purely outputting the folder name (removing the if statement shows this). Any ideas how to make it search through each subfolder?

Sub ShowFolderList()

Dim fso, folder, file, s, subfolder

Set fso = CreateObject("Scripting.FileSystemObject")

Set folder = fso.GetFolder("c:\")

Set subfolder = folder.SubFolders

For Each file In subfolder

'If LCase(Left(file.Name, 4)) = "abcd" Then
s = s & file.Name & " (" & folder.Name & ")" & vbCr
'End If

Next

Debug.Print s

End Sub

Hi wobbled,

You need to recurse the subfolders with an additional routine like this.

Recursive file search using FileSystemObject:

Option Explicit

Private Sub Command1_Click()
Dim col As Collection
Dim vFile As Variant

Set col = GetFiles("C:\temp", "*.txt")
For Each vFile In col
Debug.Print vFile
Next

End Sub

Public Function GetFiles(strPath As String, strPattern As String) As Collection
Dim fso As FileSystemObject
Dim fld As Folder
Dim col As Collection
Set fso = New FileSystemObject
Set fld = fso.GetFolder(strPath)
Set col = New Collection

CheckFolder fld, strPattern, col

Set GetFiles = col
End Function

Private Sub CheckFolder(fld As Folder, strPattern As String, col As Collection)
Dim f As File
Dim subfld As Folder
For Each f In fld.Files
If f.Name Like strPattern Then
col.Add f.Path
End If
Next
For Each subfld In fld.SubFolders
CheckFolder subfld, strPattern, col
Next
End Sub
