Excel VBA: Confirm Reference String

I have the following VBA code: ActiveSheet.Cells(2, 1) = "='C:\Test Folder\[Wkbk_Closed.xlsx]Sheet2'!$A$1"

If sheet2 does not exist in "Wkbk_Closed.xlsx" A "Select Sheet" dialog appears that asks me to select a sheet.

1) What VBA code do I use to disable the "Select Sheet" dialog.
2) What VBA code do I use to show a messagebox whenever the sheet can't be found (i.e., which initiates the "Select Sheet" dialog in part 1.)
Who is Participating?

pls try
Sub TestIfSheetsExists()
    Set Cn = CreateObject("ADODB.Connection")
    Set Rs = CreateObject("ADODB.Recordset")
    strFile = "C:\Test Folder\[Wkbk_Closed.xlsx]"
    strFileCon = Replace(Replace(strFile, "[", ""), "]", "")
    strSheet = "Sheet2"

    strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFileCon & _
            ";Extended Properties = 'Excel 12.0 Xml;HDR=YES';"
    Cn.Open strCon

    strSQL = "SELECT * FROM [" & strSheet & "$] ;"
    On Error Resume Next
    Rs.Open strSQL, Cn
    ErrNr = Err.Number
    On Error GoTo 0
    If ErrNr = 0 Then
        ActiveSheet.Cells(2, 1) = "='" & strFile & strSheet & " '!$A$1"
        MsgBox Chr(34) & strSheet & Chr(34) & "sheet not found"
    End If
End Sub

avoid using objects such as ActiveWorkbook, ActiveSheet, ActiveCell, Selection ect ... as these objects are dependant on user actions and are by nature chaotic.
As a developper, you don't want to use chaotic objects.
Prefer referencing precisely the objects you intend to use.
Dim wb As Excel.Workbook
Set wb = ThisWorkbook.

Dim ws As Excel.Worksheet
Set ws = wb.Worksheets(1)
ws.Cells(2, 1) = "........."
Set ws = Nothing
Set wb = Nothing

Open in new window

And I do not recommend the On Error Resume Next statement either, as it hide potential errors and undefined behaviors.
