I had a simple problem, I wanted to display an existing Paradox table in a data grid. Well, the help files just ran me around in circles. However, the Database/Form Wizard... did exactly what I wanted. After that, it was a simple matter to review the various properties and see how it works.

• TTable

  DatabaseName

  Just type the path. The help says that this should be the name of a database component. There is no mention anywhere that this property can accept a directory for Paradox files.

  TableName

  Name of the Paradox table

  Active

  The wizard set this false. True allows you to see the data in design mode.

  MasterSource

  Used for Parent/Child relations. MasterSource and DatabaseName are mutually exclusive - only one may have a value.

• TDataSource

  DataSet

  Set this to the name of the TTable component.

• TDBGrid

  DataSource

  Set this to the name of the TDataSource component.

• TDBNavigator

  DataSource

  Set this to the name of the TDataSource component.

• The user can change both the column widths and their order.
• The contents of memo fields won't show.
• The default columns are ok. But if you want to modify any properties, you must use the Columns Editor. Even this is a little limited - if you want to group multiple fields under a single column, then use TDBCtrlGrid.

• The contents of memo fields will show.
• There is no default vertical scroll bar
• There is no way to set the panel height if Align is other than alNone. When Align=alLeft, the PanelHeight is ignored. Therefore, the number of panels is fixed and when the user re-sizes the form, the panel height changes.
