Summary

This chapter explained some of the more advanced data entry and storage techniques available to you. I covered the use of database access and its interaction with the DataGrid. I also showed you how to use the DataGrid with just about any data source you can come up with. While I was on the subject of DataGrids, I introduced you to the static or shared class. This important class type is used extensively in .NET.

In this chapter I also covered other types of data sources, such as USB devices, RS-232, and so forth. You saw that once you get the data into your program, you can treat it like any other data you get such as that from a database.

The last part of this chapter dealt with data streams and how you can apply them to file storage, memory storage, or whatever. I showed you how to fake a simple C-like Union using the Interop services namespace of .NET. Unions can be a very fast alternative to parsing data.

So far, you have worked within the confines of what .NET provides you. The next chapter deals with ways to extend the data validation capabilities of .NET.
