DeleteOutputColumn | Deletes an IDTSOutputColumn100 object from the IDTSOutputColumnCollection100 collection. | |
DescribeRedirectedErrorCode | Provides error code information for a PipelineBuffer row added to an output buffer. | |
Equals | (Наследуется из Object.) | |
Finalize | (Наследуется из Object.) | |
GetErrorOutputInfo | Returns the index and ID of the error output of the component. | |
GetHashCode | (Наследуется из Object.) | |
GetType | (Наследуется из Object.) | |
idxOfBufferType | Инфраструктура. | |
idxOfDataRecordType | Инфраструктура. | |
Initialize | When overridden in a derived class, initializes a new instance of a custom data flow component. | |
InsertExternalMetadataColumnAt | Inserts a new external metadata column into the collection of external metadata columns at the specified index. | |
InsertInput | Adds an IDTSInput100 object to the IDTSInputCollection100. | |
InsertOutput | Adds a new IDTSOutput100 object | |
InsertOutputColumnAt | Creates a new IDTSOutputColumn100 object and inserts it into the IDTSOutputColumnCollection100. | |
IsCompatibleNumericTypes | Determines whether two numeric data types are compatible to support a conversion from one type to the other. | |
MapInputColumn | Establishes a relationship between an input column and a corresponding external metadata column. | |
MapOutputColumn | Establishes a relationship between an output column and a corresponding external metadata column. | |
MemberwiseClone | (Наследуется из Object.) | |
OnDeletingInputColumn | Deletes an IDTSInputColumn100 object from the IDTSInputColumnCollection100. | |
OnInputPathAttached | Called when an IDTSInput100 object is connected to the component through the IDTSPath100 interface. | |
OnInputPathDetached | Called when an IDTSInput100 object is disconnected from the component through the IDTSPath100 interface. | |
OnOutputPathAttached | Called when an IDTSOutput100 object of the component is attached to a downstream component. | |
PerformUpgrade | Upgrades the component metadata to the version of the component installed on the local computer. | |
PostExecute | Called at the end of component execution, but before Cleanup. | |
PreExecute | Called after PrepareForExecute, and before PrimeOutput and ProcessInput. | |
PrepareForExecute | Called before PreExecute. | |
PrimeOutput | Called at run time for source components and transformation components with asynchronous outputs to let these components add rows to the output buffers. | |
ProcessInput | Called at run time when a PipelineBuffer from an upstream component is available to the component to let the component process the incoming rows. | |
ProvideComponentProperties | Called when a component is first added to the data flow task, to initialize the ComponentMetaData of the component. | |
RegisterEvents | When you are developing a custom data flow component, you override this method to create custom events. | |
RegisterLogEntries | Registers the events that the component will log. | |
ReinitializeMetaData | Repairs any errors identified during validation that cause the component to return VS_NEEDSNEWMETADATA at design time. | |
ReleaseConnections | Frees the connections established during AcquireConnections. Called at design time and run time. | |
RemoveAllInputsOutputsAndCustomProperties | Deletes each IDTSInput100 and IDTSOutput100 object from the component. | |
SetComponentProperty | Assigns a value to a IDTSCustomProperty100 of the component. | |
SetExternalMetadataColumnDataTypeProperties | Sets the data type properties of the specified external metadata column. | |
SetExternalMetadataColumnProperty | Sets an individual property of an external metadata column. | |
SetInputColumnProperty | Assigns a value to the IDTSCustomProperty100 of an IDTSInputColumn100 object. | |
SetInputProperty | Assigns a value to the IDTSCustomProperty100 of an IDTSInput100 object. | |
SetOutputColumnDataTypeProperties | Sets the data type properties of an IDTSOutputColumn100 object. | |
SetOutputColumnProperty | Sets the value of an IDTSCustomProperty100 for an IDTSOutputColumn100 object. | |
SetOutputProperty | Sets the value of an IDTSCustomProperty100 on an IDTSOutput100 object. | |
SetUsageType | Creates an IDTSInputColumn100 object in the IDTSInputColumnCollection100 of the component and sets the UsageType property of the column. | |
ToString | (Наследуется из Object.) | |
Validate | Verifies that the component is correctly configured. |
