Whoa! I did what you said (set to false) and it really flies now! But then I
also tried a suggestion by Danny Epstein in which one loop is used to find
all databases:
MainDB = 0;
DatebookDB = 0;
ToDoDB = 0;
AddressDB = 0;
while ((DmGetNextDatabaseByTypeCreator(newSearch, &searchInfo, 'DATA',
NULL, false, &cardNo, &dbID) == 0) &&
(!DatebookDB || !ToDoDB || !AddressDB || !MainDB)) {
if (DmDatabaseInfo(cardNo, dbID, NULL, NULL, NULL, &cdate, &mdate,
NULL, NULL, NULL, NULL, NULL, &creator)) break;
if (creator == DatebookAppID) {
dbcdate = cdate;
dbmdate = mdate;
DatebookDB = DmOpenDatabase(cardNo, dbID, mode | dmModeReadOnly);
} else if (creator == ToDoAppID) {
tdcdate = cdate;
tdmdate = mdate;
ToDoDB = DmOpenDatabase(cardNo, dbID, mode | dmModeReadOnly);
} else if (creator == AddressAppID) {
AddressDB = DmOpenDatabase(cardNo, dbID, mode | dmModeReadOnly);
} else if (creator == MainAppID) {
MainDB = DmOpenDatabase(cardNo, dbID, dmModeReadWrite);
}
newSearch = false;
}
Now it rips through the file opens very quickly. In fact, now my program
launches just as fast as calculator! Sweet!
