COM object EvVariableVirtual

EvApplication > EvFileCollection > EvFile > EvVariablesCollection > EvVariableBase As EvVariableVirtual

The EvVariableVirtual object gives access to information on and actions with a virtual variable in an EV file. You can also use the EvVariableBase object to gain access to further information on and actions for the variable.

The EvFile.Variables[] property lists all the variables in an EV file and is an EvVariablesCollection.

The EvFileset.Variables[] property that lists all variables in a fileset in an EV file and is an EvVariablesCollection.

EvVariableVirtual implements the following methods and properties:

	Description
GetOperand	GetOperand(int Index) Summary Get the virtual variable's operand at operand-number Index n. The operand returned is an EvVariableBase object. Parameters Index Index is an integer that corresponds to the operand-number of an operand in the operator. The number of operands required by an operator is a function of the nature of the operator. Operands are accessed one at a time and begin with an Index of 1. Return EvVariableBase
Operator	(read-only) EOperator Operator Summary Get the EOperator enum to identify the operator for the virtual variable. Refer to EOperator for a list of the numbers and the associated operator. See also: Enum issue under VBS. Example Refer to AddVariable snippet.
OperatorName	(read-only) string OperatorName Summary Get the name of the operator that this variable is created from.
SetOperand	SetOperand(int Index, Variable) Summary Set the virtual variable's operand. Parameters Index Index is an integer that corresponds to the operand-number of an operand in the operator. The number of operands required by an operator is a function of the nature of the operator. Operands are accessed one at a time and begin with an Index of 1. Variable The acoustic variable or virtual variable as specified by EvVariableBase to be used as the operand at Index n. Return True, if successful. Example Refer to AddVariable snippet.
