To remove every object from the collection try repeatedly removing the first object in the collection until the collection is empty: Do Until (data_points. Per correggere lerrore Assicurarsi che i risultati delle assegnazioni, dei calcoli e delle conversioni dei tipi di dati non siano troppo grandi da rappresentare allinterno dellintervallo di variabili consentite per tale tipo di valore e assegnare il valore a una variabile di un tipo che può contenere un intervallo più ampio di valori, se necessario. (Maybe not quite so) obviously, the collection will still have a reference to this object. We then set data_point to Nothing to remove the reference to the object that it used to refer to. Here we are reading each item in turn from the collection into a temporary variable called data_point. Obviously the collection will still have a reference to this objectįrom Class_Terminate For Each data_point In data_points 'destruct each data point individually We then set new_data_point to Nothing to remove the reference to the object that it used to refer to. Here we are adding an object referred to by the temporary variable new_data_point to the collection. I don't think that this is necessarily the cause of your error but it is worth fixing anyway.Ĭompare and contrast these two parts of your code:įrom AddDataPoint data_points.Add new_data_point The minimization of Root Mean Squared Errors (RMSE) is carried out with Excel Solver. The container variable global_container has to be global because it must be callable from a worksheet UDF (RMSE_UDF) a worksheet formula cannot have an object as argument, as far as I know, like "=RMSE(M圜ontainer.)". Activate.This is a bad practice and can easily end up in retrieving the values from the wrong worksheet. do something with the data, have in call to global function RMSE_UDF as a cell formula for Solver I highly recommend to read How to avoid using Select in Excel VBA, the same is valid for. Set global_container= new CG_data_container Set new_data_point = Nothing 'I assume this one could also be skippedįor Each data_point In data_points 'destruct each data point individuallyĭim global_container as CG_data_container Try dimensioning RowNumber as a Long and see. Public Sub AddDataPoint(mydate as date, price as double) You get an overflow error most likely because the maximum value of a VBA Integer has been exceeded (+32,767). Here's a (simplified version) of my container class, which is used destroyed (via Set. Could an overflow error be related to some issue of having created too many objects that are not destroyed properly after use? launch the macro again from the point where the error occured. The error goes away when I restart my macro from where it stopped, i.e. excel vba ext subroutine maybe WebOn Error Exit Sub You can use On Error GoTo Line. When performing optimization tasks on a large dataset I receive an overflow runtime error 6 from time to time (generally after 1 hour or 2). They allow you to pass values over to your subroutines.
