void OpDroppedFile::DoWithParam (  OpDescriptor *  , OpParam *  pOpParam )  [virtual]

This function should be over-ridden to perform an operation which requires parameters. Author: Simon_Maneggio (Xara Group Ltd) <camelotdev@xara.com> Date: 9/6/94 Parameters: OpDesc,:  A pointer to the OpDescriptor which invoked the operation [INPUTS] pOpParam: Optional operator parameters, these are similar to a window procedures (lParam, wParam). Each operation requiring parameters will describe what these should be. -  [OUTPUTS] Returns: - Errors: - See also: Operation::Do Reimplemented from Operation.
