Assembly:  Microsoft.SqlServer.DTSRuntimeWrap (in Microsoft.SqlServer.DTSRuntimeWrap.dll)

Syntax

'Declaration
Sub LockRegion ( _
    libOffset As _ULARGE_INTEGER, _

'Usage
Dim instance As IStream 
Dim libOffset As _ULARGE_INTEGER 
Dim cb As _ULARGE_INTEGER 
Dim dwLockType As UInteger

)

void LockRegion(
    [InAttribute] _ULARGE_INTEGER libOffset, 
    [InAttribute] _ULARGE_INTEGER cb, 
    [InAttribute] unsigned int dwLockType
)

abstract LockRegion : 
        libOffset:_ULARGE_INTEGER * 
        cb:_ULARGE_INTEGER * 
        dwLockType:uint32 -> unit

function LockRegion(
    libOffset : _ULARGE_INTEGER, 
    cb : _ULARGE_INTEGER, 
    dwLockType : uint
)

Parameters

• libOffset
  Type: Microsoft.SqlServer.Dts.Runtime.Wrapper._ULARGE_INTEGER
  The byte offset for the beginning of the range.

• cb
  Type: Microsoft.SqlServer.Dts.Runtime.Wrapper._ULARGE_INTEGER
