Stop code running totally in called sub
I have a sub that calls another sub.
When an error occurs in the called sub (2nd sub) how can I make the code stop running totally and not go back to the 1st sub.
(My 2nd sub could be in the same module or in another module.)
Thanks.

i recommend deighton method which is simple
private function sub2()
On error goto Err_Handler
...
exit sub
Err_Handler:
if err.number = ### then
end
endif
end function
--
Note that the above will intercept an error and if a specified error occurs (replace ### with the desired error number) then the code will immediately stop, along with the application, and any open threads will remain open and you will lose resources...however, it will immediately stop the code as per your request!
On error goto Err_Handler
...
exit sub
Err_Handler:
if err.number = ### then
end
endif
end function

you can try the below
Sub procedure1()
call Procedure2
End sub
Sub Procedure2()
On error goto ErrHandler
'' Code in Procedure2
Exit sub
ErrHandler
end
End sub
In case you want to do for some specific errors which occur in the procedure2 then in the Error Handler code you can write as
If Err.Number = (Error number) then
END
else
MsgBox Err.descrription, vbcritical
end if
Sub procedure1()
call Procedure2
End sub
Sub Procedure2()
On error goto ErrHandler
'' Code in Procedure2
Exit sub
ErrHandler
end
End sub
In case you want to do for some specific errors which occur in the procedure2 then in the Error Handler code you can write as
If Err.Number = (Error number) then
END
else
MsgBox Err.descrription, vbcritical
end if

see rspahitz's comment
you can also create a public variable for example Sub2Err as long.
- then if an error occures in the second sub you'll simply put the error number in the variable:
Sub2Err=err.number
- now the program counter should return to sub1.
here you'll test if the public variable Sub2Err contains an error number, if so u'll stop processing otherwise u continue executing the code:
if Sub2Err <> 0 then 'some error occured
exit sub
end if
'continue executing sub1 code
you can use this method if you don't want your function to return any code or if your function is already returning something and you don't wanna pass variable by reference or let the function resturns a structure.
