Excel VBA - open a workbook and pasting data - excel

Question

I found this excellent code however I need to adapt it for my purposes.
Firstly I need to open a data workbook that is on our network. The problem I have is that it is likely at times to be open by another user and will offer the option of "read only". How can I get it to accept the read-only option so that I can commence extracting the data.
Secondly it copies using the "=" . How can I change it to copy just the values?
First macro:
Sub test()
'to open another workbook
Application.ScreenUpdating = False
Workbooks.Open Filename:=ThisWorkbook.Path & "\Schedule.xls"
ThisWorkbook.Activate
Application.ScreenUpdating = True
End Sub
2nd Macro:
Dim Sh As Worksheet
Dim Newsh As Worksheet
Dim myCell As Range
Dim ColNum As Integer
Dim RwNum As Long
Dim Basebook As Workbook
With Application
.Calculation = xlCalculationManual
.ScreenUpdating = False
End With
'Delete the sheet "Summary-Sheet" if it exist
Application.DisplayAlerts = False
On Error Resume Next
ThisWorkbook.Worksheets("Summary-Sheet").Delete
On Error GoTo 0
Application.DisplayAlerts = True
'Add a worksheet with the name "Summary-Sheet"
Set Basebook = ThisWorkbook
Set Newsh = Basebook.Worksheets.Add
Newsh.Name = "Summary-Sheet"
'The links to the first sheet will start in row 2
RwNum = 1
For Each Sh In Basebook.Worksheets
If Sh.Name <> Newsh.Name And Sh.Visible Then
ColNum = 1
RwNum = RwNum + 1
'Copy the sheet name in the A column
Newsh.Cells(RwNum, 1).Value = Sh.Name
For Each myCell In Sh.Range("A1,D5:E5,Z10") '<--Change the range
ColNum = ColNum + 1
Newsh.Cells(RwNum, ColNum).Formula = _
"='" & Sh.Name & "'!" & myCell.Address(False, False)
Next myCell
End If
Next Sh
Newsh.UsedRange.Columns.AutoFit
With Application
.Calculation = xlCalculationAutomatic
.ScreenUpdating = True
End With
End Sub

You could always open the workbook as read-only if you are only extracting data.
Instead of using .formula use .value
