    pBuffer As IVsTextLines, _
    iLine As Integer, _

    int iLine,
    int iCol,
    out int pfIsTextDataValidAtLoc
)

function IsTextDataAtLocation(
    pBuffer : IVsTextLines, 
    iLine : int, 
    iCol : int, 
    pfIsTextDataValidAtLoc : int
) : int

Parameters

• pBuffer
  Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextLines
  The text buffer.

• iLine
  Type: System.Int32
  The line number.

• iCol
  Type: System.Int32
  The column number

• pfIsTextDataValidAtLoc
  Type: System.Int32%
  [out] Zero (false) if text data is not valid at the location, otherwise non-zero (true).

Return Value

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

Remarks

This method is called on every mouse move (DragOver(UInt32, POINTL, UInt32%)). DragSetup(IDataObject, IVsTextLines, Int32%) must have been called before calling this method.
