This is what I use:
// pass in a category name
// get back a category index
// finds existing category, or adds new category if there is room, or
returns
// unfiled if no more room
Word AutoCat(CharPtr catName, DmOpenRef theDB)
{
VoidHand h = NULL;
Word foundCat;
Char seekCat[dmCategoryLength];
// try to find category
foundCat = CategoryFind(theDB, catName);
if (foundCat == 255) {
// look for an empty category slot
for (foundCat = 0; foundCat < dmRecNumCategories;
foundCat++) {
CategoryGetName (theDB, foundCat, seekCat);
if (seekCat[0] == '\0')
break;
}
if (foundCat == dmRecNumCategories)
return dmUnfiledCategory; // No more room for new
categories
// add new category
CategorySetName (theDB, foundCat, catName);
// lookup new category
foundCat = CategoryFind(theDB, catName);
}
return foundCat;
}

Subject: How To Create a Category in ToDoDB
Hi all--
I am wondering how you are supposed to create a category in a DB. I
am
finishing up writing a syncing app that runs on the palm pilot itself. I am
modifying the ToDoDB.
What I would like to do is:
1. Check to see if the category I want to store things in (ex.
'WebSync')
exists. If it does not exist I would like to create it.
2. If it does exist, I would like to get its index so I can use it
to
create records.
ANy help would be appreciated. I have looked at the docs for the DM
and
Category Structure, so I know I can use CategoryFind to see if it exists and
get the index back. But I have NO idea how to create the category
programmatically.
thanks in advance,
