    <p>Ok, lets see. First off, there are some datatypes build into the CLR. Those cannot be modified or new ones added, since they are part of the standard. You can find a list <a href="http://msdn.microsoft.com/en-us/library/exx3b86w.aspx" rel="noreferrer">here</a> or <a href="http://msdn.microsoft.com/en-us/library/ya5y69ds.aspx" rel="noreferrer">here</a>. That's C#, but the list should also exist for VB.net somewhere, and it should look equal because the underlying CLR is the same. Also, the list is not complete because floats and char are missing, but you get the idea.</p> <p>But then, there are some structs that encapsulate those Data Types and add some Extra functionality. For example, System.Int32 is just a plain standard struct, no magic involved. Feel free to look at it in Reflector, it's in mscorlib:</p> <pre><code>[Serializable, StructLayout(LayoutKind.Sequential), ComVisible(true)] public struct Int32 : IComparable, IFormattable, IConvertible, IComparable&lt;int&gt;, IEquatable&lt;int&gt; </code></pre> <p>So you want your own "1 to 10" Integer? Then I recommend looking at the nearest suitable type, which is either <code>Int16</code> or <code>Byte</code>. If you look at them, you can see that they all look somewhat similar, but that they are based on one of the built-in datatypes.</p> <p>Just copy/pasting and modifying some of the built-in structs (i.e. <code>System.Byte</code>) does not completely work because some members are internal (i.e. <code>NumberFormatInfo.ValidateParseStyleInteger</code>), but <a href="http://www.red-gate.com/products/reflector/" rel="noreferrer">Reflector</a> could help here.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
