* MODULE NAME : dlgdragi.c AUTHOR: Rick Fishman *

* DATE WRITTEN: 07-26-93 *

* *

* MODULE DESCRIPTION: *

* *

* Part of the 'DRGDROP' drag/drop sample program. *

* *

* Dialog box in the Settings notebook that handles all DRAGINFO *

* and DRAGITEM parameters except for the RMF string which is *

* handled in dlgrmf.c. *

* *

* NOTES: *

* *

* FUNCTIONS CALLABLE BY OTHER MODULES: *

* *

* wpDragInfo *

* *

* *

* HISTORY: *

* *

* 07-26-93 - Program coded. *

* 12-05-93 - Use TYPE array to convert to proper DLGINFO.szType. *
