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.
