Definition

Validates the connection and returns an enumeration that indicates success or failure.

public:
 virtual Microsoft::SqlServer::Dts::Runtime::DTSExecResult Validate(Microsoft::SqlServer::Dts::Runtime::IDTSInfoEvents ^ infoEvents);
public virtual Microsoft.SqlServer.Dts.Runtime.DTSExecResult Validate (Microsoft.SqlServer.Dts.Runtime.IDTSInfoEvents infoEvents);
abstract member Validate : Microsoft.SqlServer.Dts.Runtime.IDTSInfoEvents -> Microsoft.SqlServer.Dts.Runtime.DTSExecResult
override this.Validate : Microsoft.SqlServer.Dts.Runtime.IDTSInfoEvents -> Microsoft.SqlServer.Dts.Runtime.DTSExecResult
Public Overridable Function Validate (infoEvents As IDTSInfoEvents) As DTSExecResult

Parameters

infoEvents
IDTSInfoEvents

An object that implements the IDTSInfoEvents events interface to raise errors, warning, or informational events.

Returns

A 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.
