This page shows examples of using mv.NET with VB.NET to perform various common tasks. This page shows the exact same mv.NET examples using C#. Note that a few examples are available in one language and not the other. It's best to view both pages.

1. The mv.NET toolbox integrated into Visual Studio allows for drag and drop development for some project types.
2. Modify MV BASIC programs and MV dictionary definitions from within Visual Studio.
3. View and modify MV data in the same environment as .NET code.
4. The mv.NET schema editor is used to graphically modify exended dictionary definitions used to process MV data as though it were relational. There's no need to do this in the MV environment and no need at all to modify (flatten) or re-arrange data.
5. C# .NET sample code - create a dynamic array, pass it into a program, modify the results.
6. Visual Basic .NET sample code - create a dynamic array, pass it into a program, modify the results.
7. C# sample code - login, open a file, read and write data.
8. VB.NET sample code - login, open a file, read and write data.
9. C# sample code - login differently, open a file, read data using dictionary definitions to specify which attributes to read.
10.VB.NET sample code - login differently, open a file, read data using dictionary definitions to specify which attributes to read.
11.C# sample code - login differently, open a file, read data using dictionary definitions to specify which attributes to read.
12.VB.NET sample code - login differently, open a file, read data using dictionary definitions to specify which attributes to read.
13.VB.NET sample code - open a file without a separate account object, readv and writev data.
14.Unlike other products, mv.NET does not require a login to manipulate a dynamic array. MV developers may wish to use the DataBASIC class for common string manipulation.
15.C# example uses MV as an ADO.NET data source. A BASIC program is defined as a Stored Procedure. Arguments to the subroutine are defined as query parameters. The first parameter is set to ABC and the BASIC program is executed as a query. The second parameter of the subroutine is retrieved as a result. An MV developer wouldn't code like this, but for a Relational developer this is the standard way to execute programs against the database.
