How can the user drag and drop cells in 16-Bit?

OLE Drag and Drop is only supported under Win32.

To drag and drop cells, you have to select a range of cells and click on the edge of the inverted area and drag the cells to different views or applications. You might also select text in an edit control and drag this text to another cell or another application.

There is a new HitTest value return from CGXGridCore::HitTest which indicates whether the mouse if over the outer edge of a selection.

Under Win16, this HitTest value is not generated by default. You can force HitTest to generate this value by setting

   m_bHitTestSelEdge = TRUE;
