Sintassi

'Dichiarazione
Public Sub GetColumnFilter ( _
    eventName As String, _
    ByRef columnFilter As DTSEventColumnFilter _
)

public void GetColumnFilter (
    string eventName,
    ref DTSEventColumnFilter columnFilter
)

public:
void GetColumnFilter (
    String^ eventName, 
    DTSEventColumnFilter% columnFilter
)

public void GetColumnFilter (
    String eventName, 
    /** @ref */ DTSEventColumnFilter columnFilter
)

JScript non supporta il passaggio di argomenti di tipo valore per riferimento.

Parametri

• eventName
  The name of the event whose columns you want to control.

• columnFilter
  A DTSEventColumnFilter with values set to true or false, depending on if the column is included (true) or excluded (false).

Esempio

The following code example creates a Package and selects a log provider for it. The code example then sets the fields of the DTSEventColumnFilter to true to include that field in the log, or false to exclude the field from the log. The SetColumnFilter then defines that the fields with a value of true are logged when the package incurs an OnError event. A new DTSEventColumnFilter is created, and filled with the values from the existing filter using GetColumnFilter.
