Supporting Transfer For Customized Controls

You can modify the way a particular control transfers its data or include a new control you define in the transfer mechanism.

In either case, all you need to do is to write a Transfer member function for your control object. See the following table to interpret the meaning of the transfer flag parameter.

Transfer flag parameter	Description
tdGetData	Copy data from the control to the location specified by the supplied pointer. Return the number of bytes transferred.
tdSetData	Copy the data from the transfer buffer at the supplied pointer to the control. Return the number of bytes transferred.
tdSizeData	Return the number of bytes that would be transferred.
