Returns the position number in the text buffer, given a line and column number.

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

Syntax

'Declaration
Function GetPositionOfLineIndex ( _
    iLine As Integer, _
    iIndex As Integer, _
    <OutAttribute> ByRef piPosition As Integer _
) As Integer
'Usage
Dim instance As IVsTextLines
Dim iLine As Integer
Dim iIndex As Integer
Dim piPosition As Integer
Dim returnValue As Integer

returnValue = instance.GetPositionOfLineIndex(iLine, _
    iIndex, piPosition)

int GetPositionOfLineIndex(
    int iLine,
    int iIndex,
    out int piPosition
)

int GetPositionOfLineIndex(
    [InAttribute] int iLine, 
    [InAttribute] int iIndex, 
    [OutAttribute] int% piPosition
)

abstract GetPositionOfLineIndex : 
        iLine:int * 
        iIndex:int * 
        piPosition:int byref -> int

function GetPositionOfLineIndex(
    iLine : int, 
    iIndex : int, 
    piPosition : int
) : int

Parameters

iLine
Type: System.Int32
[in] Number of the line whose position is requested.

iIndex
Type: System.Int32
[in] Location of the character on iLine.

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.

Implements

IVsTextBuffer.GetPositionOfLineIndex(Int32, Int32, Int32%)

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextLines::GetPositionOfLineIndex(
   [in] long iLine,
   [in] CharIndex iIndex,
   [out] long *piPosition
);

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