macro that searches for a string in a folder

[Marco1975]

I all,
I'm using a macro that I found in network; this macro making a search of a string in selected folder and subfolders. I'd like that at the end of the search:

• if not found something appear the message: "no found string"
• if find something appear the message: "found "X" result"

This is the macro:

Public WS As Worksheet

Sub SearchWKBooksSubFolders(Optional Folderpath As Variant, Optional Str As Variant)
ActiveSheet.Unprotect
Dim myfolder As String
Dim a As Single
Dim sht As Worksheet
Dim Lrow As Single
Dim Folders() As String
Dim Folder As Variant
ReDim Folders(0)

If IsMissing(Folderpath) Then
    Set WS = ThisWorkbook.Sheets("CERCA_DISTINTA")
   

    With Application.FileDialog(msoFileDialogFolderPicker)
        .Show
        If .SelectedItems.Count = 0 Then Exit Sub
        myfolder = .SelectedItems(1) & "\"
    End With
   
    Str = Application.InputBox(prompt:="Inserisci stringa da cercare:", Title:="Cerca in tutte le cartelle", Type:=2)
   
    If Str = "" Then Exit Sub
   
   
    WS.Range("B1") = Str
    WS.Range("B2") = myfolder

   
    Folderpath = myfolder
   
    Value = Dir(myfolder, &H1F)
   
Else
    If Right(Folderpath, 2) = "\\" Then
        Exit Sub
    End If
    Value = Dir(Folderpath, &H1F)
End If


Do Until Value = ""
    If Value = "." Or Value = ".." Then
    Else
        If GetAttr(Folderpath & Value) = 16 Then
            Folders(UBound(Folders)) = Value
            ReDim Preserve Folders(UBound(Folders) + 1)
           
        ElseIf Right(Value, 3) = "xls" Or Right(Value, 4) = "xlsx" Or Right(Value, 4) = "xlsm" Then
            On Error Resume Next
            Workbooks.Open Filename:=Folderpath & Value, password:="zzzzzzzzzzzz"
            If Err.Number <> 0 Then
                WS.Range("A4").Offset(a, 0).Value = Value
                WS.Range("B4").Offset(a, 0).Value = "Password protected"
                a = a + 1
            Else
                On Error GoTo 0
                For Each sht In ActiveWorkbook.Worksheets
                        Set c = sht.Cells.Find(Str, LookIn:=xlValues, LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext)
                        If Not c Is Nothing Then
                            firstAddress = c.Address
                           
                            Do
                                Lrow = WS.Range("A" & Rows.Count).End(xlUp).Row
                                WS.Range("A1").Offset(Lrow, 0).Value = Folderpath

                                sht.Name & "!" & c.Address, TextToDisplay:="Link"
                                Set c = sht.Cells.FindNext(c)
                            Loop While Not c Is Nothing And c.Address <> firstAddress

For Each Folder In Folders
    SearchWKBooksSubFolders (Folderpath & Folder & "\")
