Is OnError unable to trap some kind of errors?
I have the following code:
'****************************************************************************
' LogMessage: Writes messages to a log file
'
Sub LogMessage
OnError goto ErrorHandler
Open File ApplicationDirectory$() + "MVMMapInfo.LOG" For Append As #5
Print #5, CurDate() + " " + " " + Time(24) + " " + Message
Close File #5
OnError Goto 0
Exit Sub
ErrorHandler:
Close File #5
TempText = "Error in LogMessage: " & Err() & " " & Error$() & Message
Print TempText
Call LogDebug(TempText)
OnError goto 0
Exit Sub
End Sub
However, my application occasionally crashes at the line after the OnError
line, i.e.
Open File ApplicationDirectory$() + "MVMMapInfo.LOG" For Append As #5
The error is:
"Cannot access file MVMMapInfo.LOG"
Has anyone seen this happen before where the OnError trap is ignored (or at
least I
assume it is being ignored...)
I don't have the MVMMapInfo.LOG file open at the time the error occurs, though
it is
possible that the application might not have closed it properly at it's last
attempt.
Thanks,
Dave
