When the application starts the fields will be populated with data from the database. Press F5 to build and run the application. Once the data fields are added you will notice that Visual Basic adds a toolbar to the top of the form to provide navigation and the ability to add and remove records from the database. Drag and drop the CustomerID, CompanyName, Address and Country fields onto the form so that they appear as follows: We are now ready to add some data columns to our form. Click on the '+' sign next to the Customer table to unfold the list of customer fields: The data source panel will subsequently appear listing all the data tables and columns that are available to us. The first task is to display the Data Sources Panel by selecting the Data->Show Data Sources menu option. The next step in our tutorial is to add some data fields to our application form. If you are unable to locate this database on your system it can be downloaded from Microsoft's web site. This can usually be found in "Program Files\Microsoft Office\Office nn\Samples\Northwind.mdb" (where nn signifies your version of Microsoft Office). The chapter assumes that you have Microsoft Access installed together with the NorthWind sample Access database. The concepts covered, however, apply equally to other databases such as Microsoft SQL Server. The examples in this chapter work with a Microsoft Access database. In fact, an incredible amount of database functionality can be built into a Visual Basic application without actually writing a single line of code. The next chapter will build on this knowledge by exploring Visual Basic and the DataGridView Control.Īs with most other aspects of Visual Basic and Visual Studio, Microsoft has put a significant amount of work into making it easy to work with databases. This chapter of Visual Basic Essentials is intended to provide a detailed overview of developing applications that work with databases using Visual Basic and ADO.Net.
