Forms and tables

can you have open access to forms for data entry but have the tables behind them protected so data entry people cannot mess them up

For upcoming training course dates see: Pricing & availability

RE: forms and tables

Hi Graham

Sorry for the delay in answering this question.

In Access you can block access to the actual tables but allow data entry into them via forms

One method is to hide the tables from the users view and to make the relevant forms only data entry forms.

To hide a table from view:

1. Right click on the relevant table and select Properties

2. In the Properties dialog box check the "Hideen" checkbox.

This hides the relevant table from view

To then view hidden objects

1. Select Tools , Options

2. In the Options dialog box, check the "Hidden objects" checkbox. Then click on the OK button.

This will return you back to the database window where you should now be able to see all hidden objects including the hidden tables that you are looking for.

To make a form only useful to enter new data:

1. In the forms design view right click the dot in the top, left hand corner of the form and select Properties

2. In the Properties window, select the Data tab

3. in the Data tab area change "Allow Edits" and "Allow Delitions" to NO leaving only "Allow Additions" as YES.

This way someone using the form will not see the existing data in the table and therefore cannot mess with it.

Hope this helps.

Carlos

Access tip:

Choosing data types in Access

Not sure which data type to use for your Access fields? Here are some guidelines to help you choose a data type to assign to a field.

- The Text data type can accept up to 255 characters. For information that will be recorded in paragraphs, use Memo.

- Also use Text for numbers that aren't going to be used in calculations, e.g. phone numbers.

- Use the Currency data type for monetary amounts.

- Use Date/Time for dates.

- Most other numbers can use the Number data type, but the Field Size property may have to be altered.

- For fields that have only two alternatives (yes, no) use Yes/No data type. If there is likely to be a third entry option (e.g. maybe or don't know) use Text instead.
