I'm working on a program which reads in a Dialog and then massages the
elements. How can I find the number of items in the dialog's item list?
(Under Think C)
Thanks,

If you cast this to a "dialogPeek", you can reference a field called "items" (or something like that). "Items" is a handle to the DITL list in memory, the first short word of which is the number of items in the dialog minus one. -- Pete Keleher pete@titan.rice.edu

Some of the nice routines included are: AppendDITL(theDialog,theDITL,method); numItems = CountDITL(theDialog); ShortenDITL(theDialog,numberOfItems); Also, the AppleTalk "Standard File" utilities NuLookup and NuPLookup are also included. -Michael -- Michael Niehaus UUCP: <backbones>!{iuvax,pur-ee}!bsu-cs!mithomas Apple Student Rep ARPA: mithomas@bsu-cs.bsu.edu Ball State University AppleLink: ST0374 (from UUCP: st0374@applelink.apple.com)
