'用途
Dim instance As IVsTextBuffer
Dim iLine As Integer
Dim piPosition As Integer
Dim returnValue As Integer

returnValue = instance.GetPositionOfLine(iLine, _
    piPosition)

    [InAttribute] int iLine, 
    [OutAttribute] int% piPosition
)

    iLine : int, 
    piPosition : int
) : int

Parameters

  • iLine
    Type: System.Int32
    [in] Number of the line whose position is requested.
  • piPosition
    Type: System.Int32%
    [out] Pointer to the equivalent position number.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextBuffer::GetPositionOfLine(
   [in] long iLine,
   [out] long *piPosition
);

This method might require considerable resources, depending upon the underlying implementation of the buffer. That is, it might be very difficult to calculate the size of the buffer if it is a virtual-line-oriented implementation as in Visual Basic.
