Return Value

Type: Boolean
Returns true if the span lies entirely within the source buffer and is positive; otherwise, returns false.

Remarks

The start and end points of the span are passed to the ValidCoord method and if both points test valid, the span is then tested to make sure it is positive. If that test is also true, then this method returns true.
