Valeur de propriété
The IDTSVariableDispenser90 object provided to the component.
Notes
The VariableDispenser is used to read and write variables in the package that contains the component. Before reading or writing a variable, it must be locked using one of the following methods; LockForRead, LockForWrite, LockOneForRead, or LockOneForWrite. After the variables are locked using the dispenser, they are available through the IDTSVariables90 interface.
Exemple
The following example demonstrates how to use the VariableDispenser to lock a single variable, and multiple variables.
// Lock two variables, and then retrieve them by calling GetVariables.
IDTSVariables90 variables = null;
VariableDispenser.LockForRead("variable1");
VariableDispenser.LockForRead("variable2");
VariableDispenser.GetVariables(ref variables);
object variable1 = variables[0].Value;
object variable2 = variables[1].Value;
// Retrieve a single variable.
IDTSVariables90 variables = null;
VariableDispenser.LockOneForRead("variable1", ref variables);
object variable1 = variables[0].Value;
' Lock two variables, and then retrieve them by calling GetVariables.
Dim variables As IDTSVariables90 = Nothing
VariableDispenser.LockForRead("variable1")
VariableDispenser.LockForRead("variable2")
VariableDispenser.GetVariables(variables)
Dim variable1 As Object = variables(0).Value
Dim variable2 As Object = variables(1).Value
Dim variables As IDTSVariables90 = Nothing
VariableDispenser.LockOneForRead("variable1", variables)
Dim variable1 As Object = variables(0).Value
