    int hBufferType
)

unsigned int GetColumnCount(
    [InAttribute] int hBufferType
)

abstract GetColumnCount : 
        hBufferType:int -> uint32 

function GetColumnCount(
    hBufferType : int
) : uint

參數

• hBufferType
  型別：System. . :: . .Int32
  The ID of the registered buffer.

傳回值

型別：System. . :: . .UInt32
An integer that specifies the number of columns defined for the registered IDTSBuffer100 object.
