Use of “the” prefix in object naming

First of all, most of the allergic reactions to Hungarian notation stems from the fact that consistent application tends to result in very unnatural looking names. Occasional uses of prefixes or suffixes that suggest a certain type should not be considered to be Hungarian notation unless the name looks very forced.

What you are doing by using "IsResolved" or "ResolvedOn" instead of "Resolved" is disambiguating what information is conveyed by the name (i.e. what is represented by a class or object of that name, what does a thus-named function return).

To take a few more examples:

• Company
• CompanyName
• Resolved
• IsResolved
• ResolvedOn

When reading code, "Resolved" would be the only one where I don't have an idea what it would represent and I would need to look it up. Context makes a difference and I am not claiming I am always correct, but "Resolved" is the only name in that list where I would not be able to tell at a glance if it looks to be used correctly.

If you are using an OO language that has polymorphism, it should already be apparent from the method signatures which method you need to call:

bool SaveCustomer(Customer cust)
{
    var conn = new DatabaseConnection(connectionString);
    SaveCustomer(conn, cust);
}

bool SaveCustomer(DatabaseConnection conn, Customer cust)
{
    // Save the customer
}
