This code looks wrong. DmGetNextDatabaseByTypeCreator() returns
errNone (0) if there is no error, and it returns dmErrCantFind (not 0)
if it can't find any matching dbs. Plus, I don't see how you could
compile it without at lease a compiler warning because the parentheses
are not matched.
Therefore, I think the code should be:
if (DmGetNextDatabaseByTypeCreator(true, &searchState,
myType, myCreator, false, &cardNo, &dbID) == errNone)
{
do {
count++
} while (DmGetNextDatabaseByTypeCreator(false,
&searchState, myType, myCreator, false, &cardNo, &dbID)
== errNone);
}
I haven't tested this code, so I might have made a mistake, but I
believe it is correct. Why don't you try it?
