Handling erros for Application.Workbooks without using Error handlers - vba

Question

I am trying to assign an opened workbook to an workbook object. If that workbook is not already opened, then it throws an error. I am handling the errors using an Error Handler.
This works for me:
On Error GoTo OpenWorkbookError
Set Uwk = Application.Workbooks(WbkName)
OpenWorkbookError:
If Err <> 0 Then
Err.Clear
MsgBox ("Please Open the Required Workbook")
Exit Sub
End If
But is there a way to avoid using the error handlers in this situation.

One way to do it is check each workbook name, but what's wrong with the functions in the link that #SJR gave?
In your provided code you've kept the error handler within the main body of code - it should appear between the Exit Sub and End Sub at the end of the procedure.
Something like this would work without an error handler, but it's slower as it needs to check each workbook:
Sub Test()
Dim Uwk As Workbook
Dim WbkName As String
WbkName = "PERSONAL.XLSB"
For Each Uwk In Workbooks
If Uwk.Name = WbkName Then
Exit For
End If
Next Uwk
If Not Uwk Is Nothing Then
MsgBox Uwk.Name & " found!"
Else
MsgBox "Not found."
End If
End Sub
Your version of the code should have the error handler outside the main body:
Sub Test1()
Dim WbkName As String
Dim UWk As Workbook
WbkName = "PERSONAL1.XLSB"
On Error GoTo OpenWorkbookError
Set UWk = Workbooks(WbkName)
TidyExit:
'Close anything that needs closing and Exit.
Exit Sub '<< End of main body of procedure.
OpenWorkbookError:
Select Case Err.Number
Case 9 'Subscript out of range.
MsgBox "Please open the required workbook."
Resume TidyExit
Case Else
MsgBox "Error " & Err.Number & vbCr & _
Err.Description, vbOKOnly + vbCritical
Resume TidyExit
End Select
End Sub '<< End of procedure.
