Returns the position number of a line.

public:
 int GetPositionOfLine(int iLine, [Runtime::InteropServices::Out] int % piPosition);

int GetPositionOfLine(int iLine, [Runtime::InteropServices::Out] int & piPosition);

public int GetPositionOfLine (int iLine, out int piPosition);

abstract member GetPositionOfLine : int * int -> int

Public Function GetPositionOfLine (iLine As Integer, ByRef piPosition As Integer) As Integer

Parameters

iLine: Int32

[in] Number of the line whose position is requested.

piPosition: Int32

[out] Pointer to the equivalent position number.

Returns

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.
