The basic workflow of the program is described here:

How to use DNNBuilda

1.  Enter your company name in the Company Name field.
2.  Enter your name in the Author field.
3.  Choose a namespace and class name in the next fields.
4.  To begin creating a module from an existing table, click the button beside the Table Name field.
    The "Choose SQL Table" dialog now appears.
5.  Paste the connection string from your DNN web.config file and press "Connect". Check the box to
    re-use this connection string for other sessions.
    The list box of tables now populates with choices.
6.  Pick the table you want to use and then press "OK".
    The grid is now populated with fields.
7.  Check to make sure your field mappings are correct. Verify that you have a primary key (PK) defined,
    and mappings for create (C), read (R), update (U), delete (D), and list (L).
8.  Choose the control types you would like your fields to be bound to in the generated code.
9.  Enter any custom captions, field help messages or validator message that you would like.
    If you do not enter anything for captions or field attributes, defaults will be filled in.
10. Click the button next to the Root DNN Path field & choose the root directory of your DNN installation.
    If you want the application to remember your choice, click the "Remember" checkbox.
11. Click "Generate Code". All of the files for your module will now be created in app_code and desktopmodules.
12. Click "Generate SQL". The SQL code window now appears. If you opted to remember your table from earlier,
    the connection string will be filled out for you. Click "Run Script" to generate all your SQL objects.
13. Open the DNN solution in visual studio. Your files are now part of the project. Be sure and correct any TODO:
    section in the generated code.
14. Run DNN and import the manifest file that was created for your module.
    Now you have a basic prototype with a view and edit definition!
