How to Add a Reference in VBA Editor

Hi All!

Although VBA edit does provide loads of libraries inherently, still, we may need to use few libraries which are not included by default. For example, For using Scripting.Dictionary object, or FileSystem object to search the fileSystem in an organized way, we need to add a reference to Microsoft.Scripting.Runtime.

Adding a reference purely means to instruct the VBA Compiler/Editor to include the functionality of a particular library so that we can use the functions available in the added library.

If you try to create a FileSystemObject, and write the following code:

Dim dictionary_ as Scripting.Dictionary

If we try to compile or run the code with out adding the reference it will show us the following error :



Add the reference to Microsoft.Scripting.Runtime as shown in the picture below. Go to Tools --> Reference --> Look for Microsoft.Scripting.Runtime. If you are unable to find it in the options, then you will need to browse for scrrun.dll.




Thanks,

Excel VBA : Loop through all the files and subfolders in a Folder

Hi All,

I write this function many many times in my projects. When we have to create a temporary folder which are specific to our application, then I normally have to loop through all the files in a folder and put some validations so that my code should not replace any previous temp or log files. So I thought to share a small snippet of Excel VBA code where I am trying to search all the files in a Folder ( and its subfolders too) and printing in an Excel Worksheet.

Private fileCounter As Integer
Private activeSht As Worksheet
'Display all the files in a folder. Searches all the sub folders.

'Prints Folder Names in Column A and and the file Names in Column B

Sub SearchFiles()
    Dim pth As String
    Dim fso As FileSystemObject
    Dim baseFolder As Folder
                    
    pth = "C:\Projects\" 'the base path which has to be searched for Files
    Set fso = New FileSystemObject
                    
    ''check if the folder actually exists or not
                    
    If (Not (fso.FolderExists(pth))) Then
        'the folder path is invalid. Exiting.
        MsgBox "Invalid Path"
        Exit Sub
    End If
    
    Set baseFolder = fso.GetFolder(pth)
    
    fileCounter = 1
    Set activeSht = ActiveSheet
    
    activeSht.Range("A1").Value = "Folder Name"
    activeSht.Range("B1").Value = "File Name"
    
    On Error GoTo ErrHandler
    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationManual
    PrintFileNames baseFolder
    
ErrHandler:
    Application.ScreenUpdating = True
    Application.Calculation = xlCalculationAutomatic
End Sub
    
    
Sub PrintFileNames(baseFolder As Folder)
    Dim folder_ As Folder
    Dim file_ As File
    
    For Each folder_ In baseFolder.SubFolders
        'call recursive function.
        PrintFileNames folder_
    Next folder_
    
    For Each file_ In baseFolder.Files
        'print files here
        activeSht.Range("A1").Offset(fileCounter, 0).Value = baseFolder.Path
        activeSht.Range("B1").Offset(fileCounter, 0).Value = file_.Name
        fileCounter = fileCounter + 1
    Next file_
End Sub
    

The above code loops through all the subfolders and the files in a given folder and prints the folder names in Column A and the file Names in Column B.

HTH,
