You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
The folder above contains an Access database called Films. Create a data source for this (there are 3 main tables: categories of film, certificates and the films themselves).
Create a form called frmList to contain a combobox and DataGridView. When you choose a category and certificate at the top of the form, the DataGridView should show only the films for this combination of criteria:
There are two films in the ACTION category with certificate 12
Create another form showing a single film at a time:
When you save your changes, the previous list form should reappear, to reflect any changes made
If you haven't already done so, add the necessary code so that:
- when you double-click on a film in the list (or click on the Edit button) the film automatically appears in the separate single-record form
- when you make any changes they are automatically written to the underlying database
If you've got any spare time, you could always add menus, toolbars and short-cut keys allowing a user to your forms ...
