Here's some useful stuff for you:
[from a Palm header]
// SysCreateDataBaseList can generate a list of database.
typedef struct
{
Char name[dmDBNameLength];
ULong creator;
ULong type;
UInt version;
LocalID dbID;
UInt cardNo;
BitmapPtr iconP;
} SysDBListItemType;
[from one of my apps]
// set up DB list.
if ( SysCreateDataBaseList(sysFileTApplication, NULL, &dbCount,
&gP->dbList, true) ) {
gP->dbsP = MemHandleLock(gP->dbList);
gP->dbNames = MemPtrNew(sizeof(SysDBListItemType) * dbCount);
ErrFatalDisplayIf(!gP->dbNames, "Mem allocation failed in
tapDelete()");
for (i = 0; i < dbCount; i++) {
gP->dbNames[i] = &gP->dbsP[i].name[0]; // copy ptr to name
if (cDBName) {
if (StrCompare(gP->dbNames[i], cDBName) == 0)
sel = i;
}
}
listP = PrefsGetObjectPtr(PrefsAppsList);
LstSetListChoices(listP, gP->dbNames, dbCount);
LstSetSelection(listP, sel);
LstSetHeight (listP, dbCount);
if (sel != noListSelection)
LstMakeItemVisible (listP, sel);
}
else {
ErrDisplay("No db's installed. Impossible.");
}
