Remarks
The PosChanging event is fired before the SelPos moves to a new cell. You can prevent the SelPos from changing by setting the Cancel property to 1.
The CellCurrent parameter indicates the location of the currently selected cell, and the CellNew parameter indicates the location of the cell to become selected. Each parameter contains the field and record location of the cells delimited by a semi-colon. For example, the first data cell has a value of "1;1".
Using the Cancel property to cancel the event only works if the event was qualified synchronously.
