Sets the IDTSVariableDispenser100 used to lock variables in the package for reading and writing.
Assembly: Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)
The IDTSVariableDispenser100 object is used to read and write variables in the package that contains the data flow task. Before reading or writing a variable, the variable must be locked by using one of the following methods: LockForRead, LockForWrite, LockOneForRead, or LockOneForWrite. After the variables are locked by the dispenser, they are accessible through the IDTSVariables100 interface. Because the variables are retrieved by name, you must know the name of the variable you want to read or write. It is not possible to enumerate the collection of variables.
