Well, to answer my own question. I have the following to change
the database 'type'. I call this, if and only if, I verify that the
old 'type' is still being used. It's a bit of an overkill with
all the checking.
I guess I could have just used:
ULong type;
DmSetDatabaseInfo(0, localID, NULL, NULL, NULL, NULL,
NULL, NULL, NULL, NULL, NULL, &type, NULL);
but instead I use this function.
void UpdateDatabaseType(void) {
Err error;
LocalID localID;
ULong type;
localID = DmFindDatabase(0, DBNAME);
if(localID) {
error = DmDatabaseInfo(0, localID, NULL, NULL, NULL, NULL,
NULL, NULL, NULL, NULL, NULL, &type, NULL);
}
else {
FrmCustomAlert(altNotice, "LocalID not found!", "Unable to
change", "Database 'type'!");
}
if(type == 'data') {
type = 'Data';
error = DmSetDatabaseInfo(0, localID, NULL, NULL, NULL, NULL,
NULL, NULL, NULL, NULL, NULL, &type, NULL);
FrmCustomAlert(altNotice, "Database type 'data'", "changed to
'Data'","Ok to proceed!");
}
