Hi Dave,

If On Error Resume Next is used, how long does it stay in effect? Does it
stay in effect for the entire procedure and any sub procedures it calls?
What is it's scope?

There's a lot of "more code", but this untested, uncompiled code may be closer:

Hi Dave,

This is what I'm trying to do using part of what you posted. Will this
work? I'm trying to capture when the worksheet copy errors out and prompt
the user what to do.

Sub GetTenantInfo()

Dim wbkCopyFrom As Workbook
Dim wbkCopyTo As Workbook
Dim FromwbkPath
Dim ShName As String
Dim CopyWSError As Boolean

CopyWSError = False
Set wbkCopyTo = ThisWorkbook

FromwbkPath = Application.GetOpenFilename

On Error Resume Next

Set wbkCopyFrom = Workbooks(FromwbkPath)
If wbkCopyFrom Is Nothing Then
Set wbkCopyFrom = Workbooks.Open(FromwbkPath)
On Error GoTo 0
If wbkCopyFrom Is Nothing Then
MsgBox "Cannot find originating file"
Else

Application.StatusBar = "Processing. Please Wait."
Application.ScreenUpdating = False
Application.EnableEvents = False
Application.Calculation = xlCalculationManual

My Code

'copy the sheet
Call AddSheets.UnProtectWkbook
CAMMaster.Copy After:=Sheets(ShNumber)

If Err.Number < 0 Then
Err.Clear
CopyWSError = True
GoTo Finished
Else
'no error occurred
End If

'name the sheet
ActiveSheet.Name = (ShName)
Call ProtectSht(ShName)
Call AddSheets.ProtectWkbook

More Code

Application.Calculation = xlCalculationAutomatic
Application.EnableEvents = True
Application.ScreenUpdating = True
Application.StatusBar = False

wbkCopyTo.Save

End If
End If

Finished:

If CopyWSError = True Then
wbkCopyTo.Save
MsgBox "Maximum tenant sheets copied." & vbLf _
& "Close workbook, reopen and restart 'Recreate Tenant
Sheets'"
End If

End Sub

Hi,

How do I capture a Run-time error '1004': Copy Method of Worksheet Class
failed or the like so I retain control of the code?
