Form creation is one of the best features database programs. In a previous article We saw the use of tables as information containers. Forms are the most convenient way to enter it. Since this series of articles is introductory, we focus on the use of wizards.
The assistants work with certain predefined but easily modifiable parameters. But, if we need something more specific, we will have to create a database from scratch. That will be part of another series of articles

In the previous article, you had assigned the ActiveID field the Automatic completion option. For some reason that gives an error message. In order not to block the continuity of the posts, I deactivated that option and modified the wording of the article.
The creation of forms. Thinking about comfort.
Many people use databases in their daily activities. Most do with the limited functions of a spreadsheet program. Microsoft itself does not include any chapter on Access in the books published on Microsoft Office 2019. Nor does LibreOffice have current documentation. The last LibreOffice Base manual It is version 4.
It is true that, although minimal, the use of a database program requires some theoretical knowledge. No professional user, much less an amateur not passionate about computing, usually takes the trouble to acquire it. However, the time lost in learning how to use it is more than recovered later.
Creating forms using the wizard
A form can have different shapes. The simplest form is the table.
In a table:
- Each field corresponds to a column.
- Each record corresponds to a row.
- The top row is reserved for identifying the fields.
When we finish, the table creation wizard offers us the possibility of entering data directly in the table or creating a form. After choosing the corresponding option, click on Finish.
To access the form creation wizard we must click on the corresponding icon in the database program window.
In tables and queries swe choose the table On going
Click on the double arrow to copy all the fields to the left column. Click on Next.
The following screens are used when we are going to enter data into related tables. For the moment we are going to ignore them. Click on Next.
Now we can choose the layout of the form controlso.
We call control of the form to each of the fields to be completed and to the label that identifies it. We can choose two alignment options; right and left.
In terms of layout, the options are:
- In columns, with labels on the left.
- Arranged in columns, with labels at the top, as data sheets.
- Grouped in blocks, labels go up
Once this is determined, click Next to go to the next screen.
The following parameter determines whether or not the data previously entered can be viewed from the data entry form.
In the event that the answer is no, we can adopt certain measures to prevent modifications. These are.
- Prevent the modification of the data already entered from the form
- Do not allow the addition of new data
- Make it impossible to delete existing data.
Click on Next to go to the next screen
A form must be pleasing to the eye. This is not superfluous, the easier it is to view a form, the more certain it is that the data is entered correctly.
Therefore, the penultimate screen is dedicated to choosing a border color and shape.
When we finish choosing, click on Next.
At the end, we give it a name and we can start working with the form.
I realize that I am lengthening this more than a soap opera with a large audience. Bear with me, we are going to get to the fun part, but first you have to lay the groundwork.
