Data Entry and Validation with C# and VB. NET Windows Forms

"Data Entry and Validation with C# and VB .NET Windows Forms" is a complete text on how to write effective data entry and validation code. Most books deal only with the individual pieces of .NET, such as the controls or how the .NET Framework works. This book brings together all this knowledge and shows readers how to build real programs.The old hacker adage "Garbage in, garbage out" has never been so important as it is today. With ever-increasing amounts of information flowing into and out of modern applications, the task of an application developer to control and verify information is critically important to any software project. For the first time, "Data Entry and Validation with C# and VB .NET Windows Forms" brings together current knowledge on this subject in an understandable, easy-to-read form. Covering development and best practices for data entry and validation, including GDI+, custom controls, localization, accessibility, proper data validation techniques, and best practices with Visual Basic and C#, "Data Entry and Validation with C# and VB .NET Windows Forms" is a book no modern programmer should be without. ANYoNE WHO HAS EVER worked with a computer has had to enter data into it somehow. Anyone who has done any Windows programming (or DOS programming, if you go back far enough) has had to write data entry screens. What is data entry without some kind of validation? Then again, what is validation? Validation is the process of the receiving data (via the keyboard, the mouse, voice, serial connections, and so on) and making sure that the data meets the specifications you have laid out. For instance, if you are looking for a number but receive a character, your validation code would ignore that character. I wrote this book because it encompasses pretty much what most Windows programmers do on a day-to-day basis. As programmers, we all work with data. We collect it, massage it, store it, retrieve it, and present results back to the user. As a matter of fact, data entry and validation are likely such constant themes throughout your programming day that I bet you don't even realize you're doing them. When most new programmers think of data entry, they think "Booooring!" What often comes to mind are endless screens oftext-based data entry fields for insurance companies. Where is the fun in that? After all, there is no chance for any creativity and after a few weeks of this kind of work, life becomes dull. It seems like assembly-line programming at its worst.
