DBBaseContext :: doBeforeCreate - Before create handler
The before create handler is called before creating a new data instance (DBP_Create event). The before create handler may deny creating the data instance by returning an error ( any value >0 ).
Return value: Execution error ( int32 )
The value is usually returned from context functions or actions in order to report the result of execution. The variable may contain following values:
- -1: function/action not executed
- 0: function executed normally
- 1-9: Function executed with errors. Error codes depend on the function/action called.
