C++

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

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

Implements

IVsTextBuffer::GetPositionOfLineIndex(Int32, Int32, Int32)

Remarks

COM Signature

From textmgr.idl:

C++

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.
