For example, the integer data type takes 4 bytes of space in memory. All the data types in C++ can be classified into 4 categories (or types): primitive/ built-in types, derived data types, user-defined types, and abstract data types. In this article, we will discuss the categories ...
Once you have declared the user defined type you can use the Dim statement to declare a variable of that type. DimuMyVariableAsTPerson Array A fixed array is an example of a static data structure where you know the total number of elements Arrays are linear Arrays can be resized but not ...
User-defined data types (called user-defined types (UDT) in Microsoft Visual Basic, structures in languages like C and C++, and often referred to as records in general scenarios) are groups of related data items declared as one type of information. User-defined data types are very useful ...
Use Object Explorer to create new user-defined data types. To create a user-defined data type In Object Explorer, expand Databases, expand a database, expand Programmability, expand Types, right-click User-defined Data Types, and then click New User-defined Data Type. In the New User-...
An object whose value is NULL is calledatomically null. In addition, attributes of an object can be null. These two uses of nulls are different. For example, consider thecontactstable defined as follows: CREATE TYPE external_person AS OBJECT (name VARCHAR2(30),phone VARCHAR2(20) );CREATE ...
III.C.3.Types and Enums Auser-defined type(UDT) groups related values into a single organizeddata structuremuch as a struct does in C or a record does in Pascal. The following example creates a UDT namedEmployeeto hold employee data. It then declares a variableempof theEmployeetype and ...

Using User Defined Types in COM & ATL The reason I got into this is that I've rarely used any help from newsgroups or similar communities. On the other hand since I've used code provided by other developers/programmers on CodeProject and CodeGuru it seemed reasonable to join a couple of...
