Returns a collection of the input IDs of inputs that are waiting for more data, and thus are blocking the specified input.

System_CAPS_pubmethodGetErrorOutputInfo(Int32, Int32)

Returns the index and ID of the error output of the component.

System_CAPS_protmethodSystem_CAPS_staticIsCompatibleNumericTypes(DataType, DataType)

Determines whether two numeric data types are compatible to support a conversion from one type to the other.

System_CAPS_pubmethodIsInputReady(Int32[], Boolean[])

Determines which of the inputs attached to a component are waiting for more data, and which have enough data to process and are blocked.

System_CAPS_pubmethodMapInputColumn(Int32, Int32, Int32)

Establishes a relationship between an input column and a corresponding external metadata column.

System_CAPS_pubmethodMapOutputColumn(Int32, Int32, Int32, Boolean)

Establishes a relationship between an output column and a corresponding external metadata column.


(Inherited from Object.)

System_CAPS_pubmethodOnDeletingInputColumn(Int32, Int32)

Called when an IDTSInput100 object is connected to the component through the IDTSPath100 interface.


Called when an IDTSInput100 object is disconnected from the component through the IDTSPath100 interface.


Called when an IDTSOutput100 object of the component is attached to a downstream component.

System_CAPS_pubmethodPerformDowngrade(Int32, DTSTargetServerVersion)


Upgrades the component metadata to the version of the component installed on the local computer.


Called at the end of component execution, but before Cleanup.


Called after PrepareForExecute, and before PrimeOutput and ProcessInput.


Called before PreExecute.

System_CAPS_pubmethodPrimeOutput(Int32, Int32[], PipelineBuffer[])

Called at run time for source components and transformation components with asynchronous outputs to let these components add rows to the output buffers.

System_CAPS_pubmethodProcessInput(Int32, PipelineBuffer)

Called at run time when a PipelineBuffer from an upstream component is available to the component to let the component process the incoming rows.


Called when a component is first added to the data flow task, to initialize the ComponentMetaData of the component.


When you are developing a custom data flow component, you override this method to create custom events.


Registers the events that the component will log.


Repairs any errors identified during validation that cause the component to return VS_NEEDSNEWMETADATA at design time.


Frees the connections established during AcquireConnections. Called at design time and run time.


Deletes each IDTSInput100 and IDTSOutput100 object from the component.

System_CAPS_pubmethodSetComponentProperty(String, Object)

Assigns a value to a IDTSCustomProperty100 of the component.
