ComponentOne True DBInput Pro 8.0

Nineteen tutorials are presented in this chapter. The tutorials assume that you are familiar with programming in Visual Basic, know what a Data control is, and know how to use the Visual Basic built-in Data control with bound controls in general. The tutorials provide step-by-step instructions—no prior knowledge of True DBInput is needed. By following the steps outlined in this chapter, you will be able to create projects that demonstrate a variety of True DBInput features, which will give you a good sense of what the input controls can do and how to do it.

The tutorials use an Access database, TDBIDemo.MDB. The database files TDBIDemo.MDB, TDBIDemo.SAV, and the tutorial projects are in the TUTORIAL subdirectory of the True DBInput installation directory. TDBIDemo.SAV is a backup copy of TDBIDemo.MDB. If you want to restore TDBIDemo.MDB after editing, adding, or deleting records while using the tutorials, make a new copy of TDBIDemo.MDB from TDBIDemo.SAV.

We encourage you to run the tutorial projects in Visual Basic, examine the code, and experiment with your own modifications. This is the best and quickest way to learn how to realize the full potential of True DBInput. You will find that True DBInput is very easy to use, and it enables you to create powerful database applications.

The tutorials assume that the database file TDBIDemo.MDB is in the C:\ProgramFiles\ComponentOneStudio\Common directory, and refer to it by filename instead of the full pathname for the sake of brevity.

Note: Depending on where you store the projects and database files in the TUTORIAL subdirectory, you may need to change the DatabaseName property of the Data control in the tutorial projects in order for the projects to work properly.

The project chosen for tutorials 16, 17, 18, and 19 is a simple one, with the forms and database files you might find in a restaurant's payroll system for time and tips reporting.

Please be advised that this ComponentOne software tool is accompanied by various sample projects and/or demos which may make use of other development tools included with ComponentOne Studio Enterprise.
