I am using the simple code below to handle the error. When there is no error in why does the msgbox appears? How can I make the msgbox appear only when there is an error?
Sub Test()
On Error GoTo ErrHandler
On Error GoTo 0
'rest of the code is here
ErrHandler:
MsgBox "Please make sure the file exists in the current folder."
Exit Sub
End Sub
You should add an exit before the actual error handler and restore the default error handling after having shown the dialog. (The 1st on error goto 0 is probably misplaced).
Sub Test()
On Error GoTo ErrHandler
'rest of the code is here
'Exit before error handlers
Exit Sub
ErrHandler:
MsgBox "Please make sure the file exists in the current folder."
' Reset error handler
On Error GoTo 0
Exit Sub
End Sub

I use a workbook that copy information from others workbooks, using the following Code:
Sub importarbens()
On Error GoTo ErrorHandler
{...}
ErrorHandler:
Workbooks(nomearq2).Close
MsgBox "Arquivo Incompatível"
Exit Sub
End Sub
But apparently my code always get in the ErrorHandler, even when the code runs withouth erros and after the task is done. The message in message box appears
When I disable the errorhandler the code works well
You need to add Exit Sub:
Sub importarbens()
On Error GoTo ErrorHandler
{...}
Exit Sub '<< end of the "happy path" for your code....
ErrorHandler:
Workbooks(nomearq2).Close
MsgBox "Arquivo Incompatível"
Exit Sub '<< Don't really need this since you're already
' at the end of the sub
End Sub
I am trying to add error handling for one of the code. I am assigning worksheet with specific name to the sheet objects, now I am trying to add OnError statements if in case user changes the names of sheets then code should gracefully exit the sub after displaying a message to correct the file names.
But the problem is as I provide the structure as below then the sub exit code always executes even if the file name is ok.
The problem is, as I provide the details in the structure as below then the sub exit code always executes even if the file name is ok.
Private Sub DoSomething()
On Error GoTo CleanFail
'...code...
CleanExit:
'cleanup code here
Exit Sub
CleanFail:
If Err.Number = 9 Then 'subscript out of range
Err.Clear
Resume Next
Else
MsgBox Err.Description
Resume CleanExit
End If
End Sub
On Error GoTo ErrorFailLoad
Set LoadSheet = Application.ActiveWorkbook.Worksheets("Load_Template")
ErrorExit:
End Sub
ErrorFailLoad:
MsgBox "Main File name must be Load_Template. Please change and re-run Macro"
Resume ErrorExit
On Error GoTo ErrorFailEquip
Set EquipSheet = Application.ActiveWorkbook.Worksheets("EQUIP")
ErrorExit:
End Sub
ErrorFailEquip:
MsgBox "Equipment File name must be EQUIP. Please change and re-run Macro"
Resume ErrorExit
I expect the code to just check if the file name is not available then just show error message and exit. Actual results is code exit even after correct file name.
Please see my Sub below. If an error occurs whilst running the MyMacro Macro, it doesn't go to the ErrHandler and just behaves as the Default i.e. On Error Goto 0
Sub GoGoGo()
On Error GoTo ErrHandler
Application.Run "'MyFile.xlsm'!Module1.MyMacro"
Msgbox("Success!")
Exit Sub
ErrHandler:
MsgBox ("Error")
End Sub
Is there a way around this?
Many thanks in advance to any help received :)
Try this maybe? Im new to VBA but might work.
Sub GoGoGo()
On Error Resume Next
Application.Run "'MyFile.xlsm'!Module1.MyMacro"
Msgbox "Success!"
On Error goto 0
MsgBox "Error"
End Sub
I have VBA code that is supposed to be nested error checking, but it does not. The code is psuedo as below. However, whenever an error occurs within an error (For instance, an error is tripped in the loop, goto SmallError occurs, and an error occurs in SmallError) The second GoTo is not used. The error then breaks the code.
Ex:
Error in Loop
GoTo SmallError
Error in SmallError
Code Breaks (Here code should GoTo FatalError)
Sub DoThings()
On Error GoTo SmallError
'Coding Happens
Do While(conditionhere)
'Looping things happen
GoTo LoopResume
SmallError:
source = Err.source
descript = Err.Description
On Error GoTo Fatal Error
'Small error processing happens
Resume LoopResume
FatalError:
source = Err.source
descript = Err. Description
On Error GoTo ExitError
'Fatal Error processing happens
ExitError:
Exit Sub
LoopResume:
count = count + 1
Loop
On Error GoTo FatalError
'Finishing code happens
End Sub
You can't use an On Error statement within an error handler. See e.g. this article that explains this.
What you CAN do however is to have a separate routine that handles the "regular error". This routine can have a "fatal error" handler. Your code would then look something like this:
(Edit: Edited the code to enable exit when there is a fatal error):
Sub DoThings()
On Error GoTo SmallError
Dim fatalExit As Boolean
'Coding Happens
Do While(conditionhere)
'Looping things happen
LoopResume:
count = count + 1
Loop
On Error Goto SmallError2
'Finishing code happens
Exit Sub
SmallError:
handleError Err.Source, Err.Description, fatalExit
If fatalExit Then
Exit Sub
Else
Resume LoopResume
End If
SmallError2:
handleError Err.Source, Err.Description, fatalExit
Exit Sub
End Sub
Private Sub handleError(ByVal source As String,ByVal description As String, ByRef fatalExit As Boolean)
On Error Goto FatalError
'Do "small error" handling here
Exit Sub
FatalError:
fatalExit = True
'Do "fatal error" handling here
End Sub
... you have Fatal Error in your Goto rather than FatalError, that won't get you to the right location...
Update your code to:
On Error GoTo FatalError
This question already has answers here:
Why VBA goes to error handling code when there is no error?
(5 answers)
Closed last year.
I need to catch some VBA errors using the GoTo statement:
Sub mySub
On Error GoTo errorHandler:
Workbooks.Open("myWorkbook")
'
' Some Code
'
errorHandler:
MsgBox "ERROR"
End Sub
The problem is that when there is no error the errorHandler section is executed.
I found this discussion but the answer doesn't solve my issue.
I tried adding an Exit Sub statement as explained :
Sub mySub
On Error GoTo errorHandler:
Workbooks.Open("myWorkbook")
Exit Sub
'
' Some Code
'
errorHandler:
MsgBox "ERROR"
End Sub
In this case it exits the method when there is no error.
I also tried :
Sub mySub
On Error GoTo errorHandler:
Workbooks.Open("myWorkbook")
'
' Some Code
'
errorHandler:
MsgBox "ERROR"
Exit Sub
End Sub
But still the same issue: The errorHandler is executed even when no errors occur.
Just put Exit sub in.
Sub mySub
On Error GoTo myHandler:
Workbooks.Open("myWorkbook")
'
' Some Code
'
Exit sub
myHandler:
MsgBox "EROOR !"
err.clear
End Sub
Here's the pattern I prefer:
Sub SomeSub()
On Error GoTo ErrorLabel
'Code goes here
ExitLabel:
'Clean-up code, if any, goes here
Exit Sub
ErrorLabel:
'Error-handling code goes here
Resume ExitLabel
End Sub
Note that Resume clears the error. I like this pattern for a few reasons:
Habitually inserting the exit block before the error-handling block reduces the chance that I'll have the OP's problem of accidentally dropping into the error handler.
I use GoTo ExitLabel for any early exit from the Sub or Function. This way, I'm less likely to skip the clean-up code by accident. Example:
Sub SomeOtherSub()
Dim x As ResourceThatNeedsToBeClosed
Dim i As Long
On Error GoTo ErrorLabel
Set x = GetX
For i = 1 To 100
If x.SomeFunction(i) Then
GoTo ExitLabel
End If
Next
ExitLabel:
x.Close
ErrorLabel:
'Error-handling code goes here
Resume ExitLabel
End Sub
Public Sub MySub
On Error Goto Skip
' Some Codes
Skip:
If err.Number > 0 Then
' Run whatever codes if error occurs
err.Clear
End If
On Error Goto 0
End Su
I am having the exact same issue as you, and the solutions above did not work. They clearly didn't even see you wrote Exit Sub in already in 2 different places in your original post. No site online seems to understand that sometimes there won't be an error (if there was always going to be an error, why did you code it that way?), and when there isn't an error, you obviously don't want to Exit Sub. Nor do you want the myHandler to run when there isn't an error. DUH! This is the solution I cam up with which seems to work.
On Error GoTo ErrorHandler
'This is the thing I am trying to do...
Workbooks("SpreadSolver.xlsb").Activate
'If it works, great.
'Don't touch the error stuff and move on.
'I.e. go to the part that I know works (the rest of the macro)
GoTo ThisPartWorks
'If the thing I am trying to do doesn't work...
ErrorHandler:
MsgBox "Error: Please open Spread Solver and then run the macro."
'Only want to Exit Sub if there is an error.. duh.
Exit Sub
ThisPartWorks:
'the rest of your macro can go here...
'...
End Sub
I use an If statement, within the ErrorHandler, which will stop execution if there is no error. This is achieved by using the Err.Number (Err (object) number (e.g. Run-time error 9: Subscript out of range))
If Err.Number >= 1 Then
MsgBox ("Message")
End
Else: other code
End If
Exit Sub
This is what I have done. Works like a charm
Sub someProgram ()
On Error goto Handler:
x = 7/0
'Some code you wanna execute with or without error
Exit Sub
Handler:
'Write your handler here
Resume next 'After handling error, this line will help you resume the next line
End sub
Use below code in error handler section:
if err.number>0 the
' error handling goes here
else
' some code
end if
sub XYZ ()
on error goto label
"Write your macro"
Label:
If Err.Description <> "" Then
"your code if error occurs for eg:"
msgbox "Error Occured!"
Exit Sub
Else
"Your code when no error occurs for eg"
msgbox " Done."
End If
Exit Sub
