IVsTextBuffer.GetSize Method

Returns the size in characters of the buffer.

Namespace:  Microsoft.VisualStudio.TextManager.Interop
Assembly:  Microsoft.VisualStudio.TextManager.Interop (in Microsoft.VisualStudio.TextManager.Interop.dll)

Syntax

'宣言
Function GetSize ( _
    <OutAttribute> ByRef piLength As Integer _
) As Integer
int GetSize(
    out int piLength
)
int GetSize(
    [OutAttribute] int% piLength
)
abstract GetSize : 
        piLength:int byref -> int 
function GetSize(
    piLength : int
) : int

Parameters

  • piLength
    Type: System.Int32%
    [out] Pointer to the size of the buffer, which is not necessarily the same value as the size of the buffer's internally-allocated memory or the size of the file (if any) represented by the buffer.

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::GetSize(
   [out] long *piLength
);

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.
