vba Excel - How to Check if a SharePoint Website File is Open - vba

Question

I've searched the internet for the answer to this and keep running into issues getting it to work.
I need to check if a file at the below location is open/locked, and then have the code wait 15 seconds and then try again. Right now if someone else has the file open a dialog box opens asking if I want to open read only, which I don't want. I tried using Application.DisplayAlerts = False to get the message not to appear but that didn't seem to work. So I have two main issues:
Checking if the file is open and waiting to try again.
Stop the dialog box from opening asking to open as read only.
Workbooks.Open filename:= _

Answer 1

Try something like this:
From MSDN site:
https://msdn.microsoft.com/en-us/library/office/ff193284.aspx
Sub UseCanCheckOut(docCheckOut As String)
Dim docCheckout
set docCheckout="File name to open"
' Determine if workbook can be checked out.
If Workbooks.CanCheckOut(Filename:=docCheckOut) = True Then
Workbooks.CheckOut (Filename:=docCheckOut)
Else
Found at the MSDN Website:
https://msdn.microsoft.com/en-us/library/office/ff822851.aspx
Application.Wait(Now + TimeValue("0:00:10"))
Workbooks.CheckOut (Filename:=docCheckOut) 'Try to check the file out again.
End If
End Sub
This part is covered in the
IF workbooks.cancheckout(filename:=docCheckout)=true then workbooks.checkout ' method in part 1.
