Gets the DTP_BUFFCOL structure for a column in the specified buffer definition.

命名空间：  Microsoft.SqlServer.Dts.Pipeline.Wrapper
程序集：  Microsoft.SqlServer.DTSPipelineWrap（在 Microsoft.SqlServer.DTSPipelineWrap.dll 中）

语法

声明
Public Overridable Sub GetColumnInfo ( _
    hBufferType As Integer, _
    hCol As Integer, _
    <OutAttribute> ByRef pCol As DTP_BUFFCOL _
)
用法
Dim instance As DTSBufferManagerClass
Dim hBufferType As Integer
Dim hCol As Integer
Dim pCol As DTP_BUFFCOL

instance.GetColumnInfo(hBufferType, hCol, _
    pCol)

public virtual void GetColumnInfo(
    int hBufferType,
    int hCol,
    out DTP_BUFFCOL pCol
)

public:
virtual void GetColumnInfo(
    [InAttribute] int hBufferType, 
    [InAttribute] int hCol, 
    [InAttribute] [OutAttribute] DTP_BUFFCOL% pCol
)

abstract GetColumnInfo : 
        hBufferType:int * 
        hCol:int * 
        pCol:DTP_BUFFCOL byref -> unit 
override GetColumnInfo : 
        hBufferType:int * 
        hCol:int * 
        pCol:DTP_BUFFCOL byref -> unit 

public function GetColumnInfo(
    hBufferType : int, 
    hCol : int, 
    pCol : DTP_BUFFCOL
)

参数

实现

IDTSBufferManager100. . :: . .GetColumnInfo(Int32, Int32, DTP_BUFFCOL%)

注释

This method retrieves the DTP_BUFFCOL structure for the column specified by the hCol parameter in the specified buffer type definition. If the buffer definition or the column is not found, an E_INVALIDARG error occurs.
