Getting the "Do you want to overwrite the file" dialog box to show when saving with VBA - vba

Question

The following code saves a selected area of my excel sheet. If I try to save a file that has the same file name as one that already exists, however, it will just save the file without showing the "Do you want to overwrite the file" dialog box.
Is there a way to change this code so that it will ask if I would like to overwrite the preexisting file?
Option Explicit
Sub CreatePDF()
Dim wSheet As Worksheet
Dim vFile As Variant
Dim sFile As String
Set wSheet = ActiveSheet
sFile = Replace(Replace(wSheet.Name, " ", ""), ".", "_") _
& "_" _
& Format(Now(), "yyyymmdd\_hhmm") _
& ".pdf"
sFile = ThisWorkbook.Path & "\" & sFile
vFile = Application.GetSaveAsFilename _
(InitialFileName:=sFile, _
FileFilter:="PDF Files (*.pdf), *.pdf", _
Title:="Select Folder and FileName to save")
If vFile <> "False" Then
wSheet.Range("B2:J44").ExportAsFixedFormat _
Type:=xlTypePDF, _
FileName:=vFile, _
Quality:=xlQualityStandard, _
IncludeDocProperties:=True, _
IgnorePrintAreas:=False, _
OpenAfterPublish:=False
MsgBox "PDF file has been created."
End If
End Sub

Answer 1

One way to simulate the behavior, as suggested, is to check the selected SaveAsFilename:
Option Explicit
Sub CreatePDF()
Dim wSheet As Worksheet
Dim vFile As Variant
Dim sFile As String
Set wSheet = ActiveSheet
sFile = Replace(Replace(wSheet.Name, " ", ""), ".", "_") _
& "_" _
& Format(Now(), "yyyymmdd\_hhmm") _
& ".pdf"
sFile = ThisWorkbook.Path & "\" & sFile
vFile = Application.GetSaveAsFilename _
(InitialFileName:=sFile, _
FileFilter:="PDF Files (*.pdf), *.pdf", _
Title:="Select Folder and FileName to save")
If Dir(vFile) > vbNullString Then _
If MsgBox("Overwrite File?", _
vbExclamation + vbYesNo, "Overwrite?") = vbNo Then Exit Sub
If vFile <> "False" Then
wSheet.Range("B2:J44").ExportAsFixedFormat _
Type:=xlTypePDF, _
Filename:=vFile, _
Quality:=xlQualityStandard, _
IncludeDocProperties:=True, _
IgnorePrintAreas:=False, _
OpenAfterPublish:=False
MsgBox "PDF file has been created."
End If
End Sub

Another alternative:
Replace:
vFile = Application.GetSaveAsFilename _
(InitialFileName:=sFile, _
FileFilter:="PDF Files (*.pdf), *.pdf", _
Title:="Select Folder and FileName to save")
If vFile <> "False" Then
By:
With Excel.Application.FileDialog(msoFileDialogSaveAs)
Dim i As Integer
For i = 1 To .Filters.Count
If InStr(.Filters(i).Extensions, "pdf") <> 0 Then Exit For
Next i
.FilterIndex = i
.InitialFileName = sFile
.Title = "Select Folder and FileName to save"
'------------------- Bloc A -------------------------
If CBool(.Show) Then
vFile = .SelectedItems.Item(.SelectedItems.Count)
End If
If vFile <> "" Then
'------------------- Bloc A -------------------------
'----------- Or replace "Bloc A" by------------------
'If Not CBool(.Show) Then Exit Sub
'vFile = .SelectedItems.Item(.SelectedItems.Count)
'And remove the "If vFile <> "False" Then" check
'----------------------------------------------------
End With
If you selected an existing file, the overwrite message will show
