Outlook VBA add hyperlink of chosen file in dialog - vba

Question

I'm trying to add the functionality in my Outlook (with VBA, I guess is easiest) to add a simple file dialog which takes the path of any files chosen and adds them to the email body as a hyperlink.
The idea of this is for network files to be shared amongst colleagues, instead of attaching them to the email, but just as easy to do.
This is my code so far, I can't even get the dialog to open, and I've had a good look at trying to get COMDLG32.ocx, so far I can't seem to make anything work.
Sub Main2()
Dim CDLG As Object
Set CDLG = CreateObject("MSComDlg.CommonDialog")
With CDLG
.DialogTitle = "Get me a File!"
.Filter = _
"Documents|*.doc|Templates|*.dot|Text Files|*.txt"
.ShowOpen
MsgBox .FileName
End With
Set CDLG = Nothing
End Sub
Thanks in advance, hopefully someone can show me how this is done!
Just for those who need it; OS Windows 10, Office 2010 H&B (yes, I know it's out of date :))

Answer 1

There seems to be no direct way to open a FileDialog in Outlook 2010 VBA.
The following macro (inspired by a related post) makes use of Excel to circumvent this:
Public Function promptFileName(title As String, filter As String) As String
' requires project reference to "Microsoft Excel 14.0 Object Library"
Dim xlObj As Excel.Application
Dim fd As Office.FileDialog
Dim name As String
Dim vItem As Variant
Dim filterArray() As String
Dim i As Integer
Set xlObj = New Excel.Application
xlObj.Visible = False
Set fd = xlObj.Application.FileDialog(msoFileDialogOpen)
name = ""
With fd
.title = title
.ButtonName = "Ok"
.Filters.Clear
filterArray = Split(filter, "|")
For i = LBound(filterArray) To UBound(filterArray) - 1 Step 2
.Filters.Add filterArray(i), filterArray(i + 1), 1 + i \ 2
Next i
If .Show = -1 Then
For Each vItem In .SelectedItems
name = vItem
Exit For
Next
End If
End With
xlObj.Quit
Set xlObj = Nothing
promptFileName = name
End Function
Private Sub testPromptFile
Dim name as String
name = promptFileName("a test", "Text Files (*.txt)|*.txt|All Files (*.*)|*.*")
MsgBox name
End Sub
Outlook 2013 and beyond provide an Office.FileDialog class for this purpose.

You can press a button with Outlook VBA.
Sub ExecuteMso_strId()
Dim objItem As Object
Dim strId As String
' Text appears when hovering over icon
' when adding buttons to a Quick Access toolbar or a ribbon
strId = "HyperlinkInsert"
On Error Resume Next
Set objItem = ActiveInspector.currentItem
On Error GoTo 0
If Not objItem Is Nothing Then
ActiveInspector.CommandBars.ExecuteMso (strId)
Else
ActiveExplorer.CommandBars.ExecuteMso (strId)
End If
End Sub
With this you do not have access to the parameters as with Excel.
