Memo Count

Postby handfordr on Fri Sep 06, 2002 11:38 am

All,

I am trying to count the number of records in a memo, and I am consitently returned an incorrect number regardless of tghe number of lines. The code is below and I am running it on an M515 with 4.1 OS. Can anyone assist.

main()
{
int recs;

mmfind("test memo");
recs=mmcount();
alert(recs);
}

Kind Regards

When a memo is deleted in the PalmOS, the record is emptied out but not removed until the next hotsync. I don't believe these "deleted" records are counted with the mmcount call, however the empty records will still be there.

I'm unsure what it is you want to count.

If it is memos in the memopad use mmcount().


If you want to know the number of lines in a memo:

Open it with mmfind()
make sure you're at the top with mmrewind()
and then
(while not mmeof())
mmgetl(i++)
alert("There are "+i+" lines in this memo")

cheers

Guys,

Thanks for you help here, I was being particularly thick, and thinking that mmcount return the number of lines in a memo rather than the number of memos in tha database.

Again thanks for you help, and I'll go back under my stone now.
