Consistency of "Cancel" parameter in events

In some CJ events there is a parameter, usualy called "Cancel", that allow us to cancel a operation.

This parameter is, in the majority of the cases, a boolean, but in some cases is a "Variant". When it happens the operation is never canceled when I change the parameter value to TRUE, and I need to wrap the control in VB6 to change the parameter type to boolean. 

I believe that there isn't a real reason to define the "Cancel" parameter as a Variant, and it's just a programmer decision at the moment.

There are only a few cases in just a few CJ Controls (KeyBindings, TabControl, TabToolbar, PropertyGrid, ReportControl and TrackControl). In all other cases the parameter is properly defined as a boolean.

As I don't think I'm the only one (potentially) having problems with this, do you think it's possible to change it in the future?

Thank you

Yes, I'm sure the problem is in Visual Objects side as it doesn't support the VB variant type, but it's more or less common with non MS languages, I believe.

Still, unless there's a reason to not do so, it seems logical that the Cancel parameter should be always a boolean for product consistency, efficiency and performance.

I don't have that, but I will investigate.

Thanks
