- connections
- Connections
A collection of connections used by the task.
- variableDispenser
- VariableDispenser
A VariableDispenser object for locking variables.
- events
- IDTSComponentEvents
An object that implements the IDTSComponentEvents interface.
- log

Returns
A value from the DTSExecResult enumeration.
Examples
The following code example shows how to validate objects using the Validate method of the Package object.
DTSExecResult myresult = pkg.Validate(myPkgConnections, myPkgVariables, myIDTSEvents, myIDTSLogging);
Dim myresult As DTSExecResult = pkg.Validate(myPkgConnections,myPkgVariables,myIDTSEvents, myIDTSLogging)
Remarks
The Validate method reviews properties and settings for inaccuracies or incorrect settings. The method does not touch data, or connect to data sources to validate connections. However, it ensures that required fields are populated and contain appropriate values. The fields that are validated differ depending on what object is being validated.
The primary use of Validate is when writing a custom task. The Validate method is called by the SSIS Designer when a task is dropped onto the design surface and again, potentially multiple times, when properties are being set. However, in code, the Validate method on individual objects is not commonly used, as it is recommended that you call the Validate method on the Package when you need to validate objects. However, the method is available on individual objects should you find a unique circumstance where it is needed.
The Validate method is overridden in custom tasks, either for validation of the object when used in the SSIS Designer, or when called by code. For more information on writing the Validate method for a custom task, see Coding a Custom Task.
