Syntax

'Declaration
Private Function IsActiveVariable ( _
    rowVid As Integer, _
    varVid As Integer _
) As Boolean Implements INonlinearModel.IsActiveVariable

bool INonlinearModel.IsActiveVariable(
    int rowVid,
    int varVid
)

private:
virtual bool IsActiveVariable(
    int rowVid, 
    int varVid
) sealed = INonlinearModel::IsActiveVariable

private abstract IsActiveVariable : 
        rowVid:int * 
        varVid:int -> bool 
private override IsActiveVariable : 
        rowVid:int * 
        varVid:int -> bool

JScript does not support explicit interface implementations.

Parameters

rowVid
Type: System.Int32
the row index

varVid
Type: System.Int32
the variable index

Return Value
