Managing the sub-errors

Several functions generate two levels of error. These two error levels are used to narrow down the cause of the error, for example by performing a simple browse between the different sub-errors (see example).

The main functions generating sub-errors are: HCreateView, HExecuteView, HViewToFile, ...
