'宣告
Sub GetData ( _
    dwOffset As UInteger, _
    ByRef lpPointer As Byte, _

'用途
Dim instance As IDTSBLOBObject100
Dim dwOffset As UInteger
Dim lpPointer As Byte
Dim dwLength As UInteger
Dim lpdwWritten As UInteger

instance.GetData(dwOffset, lpPointer, _
    dwLength, lpdwWritten)

void GetData(
    uint dwOffset,
    ref byte lpPointer,
    uint dwLength,
    out uint lpdwWritten
)

void GetData(
    [InAttribute] unsigned int dwOffset, 
    [InAttribute] unsigned char% lpPointer, 
    [InAttribute] unsigned int dwLength, 
    [OutAttribute] unsigned int% lpdwWritten
)

abstract GetData : 
        dwOffset:uint32 * 
        lpPointer:byte byref * 
        dwLength:uint32 * 
        lpdwWritten:uint32 byref -> unit 

function GetData(
    dwOffset : uint, 
    lpPointer : byte, 
    dwLength : uint, 
    lpdwWritten : uint
)

參數

  • lpdwWritten
    型別：System. . :: . .UInt32%
    An out parameter that indicates the number of bytes written to the lpPointer parameter.

備註

This method is used to retrieve a set of bytes from the IDTSBLOBObject100.
