2.5. Creating First Object

 

2.5.1. Creating Object

It's time to create the first object - a table for storing and displaying information about users that will use the system. For convenience we divide the task into simpler steps:

adding the object;

grid design to display data from database;

form design to input / output / change / delete data to / from the database.

 

To add an object:

 

2.5.1.1. Open the context menu clicking the right mouse button on the folder 1400 User;

 

 

2.5.1.2. Select New Object Table;

 

 

2.5.1.3. In the window Properties in the field Object Code type in 1401;

2.5.1.4. In the field Object Name type in User;

 

 

2.5.1.5. Press Enter.

 

 

 

2.5.2. Grid Design

To design grid:

 

2.5.2.1. Move the mouse pointer to the object 1401 User in the folder 1400 User;

2.5.2.2. Open an item to change by double-clicking the left mouse button;

 

 

Note: if you want to study grid design process in detail, follow the steps 2.5.2.3 - 2.5.2.11. If you already know how to do this, skip the steps 2.5.2.3 - 2.5.2.11 and go to the step 2.5.2.12.

 

2.5.2.3. In the field Data Source specify the object - vw_users;

 

 

2.5.2.4. In system fields Record ID (a unique record ID), Date & Time (Created) (date and time when record was created), Date & Time (Updated) (date and time when record was updated), Date & Time (Closed) (date and time when record was closed), User ID (ID of the user who created the record), select accordingly fields user_iddttmcrdttmupdttmcluserid;

 

 

2.5.2.5. Open the context menu by right-clicking in the empty space of the object, choose Add a column and select columns user_iduser_fullnameuser_loginuser_password;

 

 

2.5.2.6. Select each column by clicking the left mouse button on any line of the table, specify in the field Caption the displayed name of the column - ID, Fullname, Login, Password accordingly;

 

 

 

 

2.5.2.7. Move the mouse pointer over the border between the headings of the first and the second column;

2.5.2.8. Click the left mouse button and, without releasing it, change the width of the first column;

 

 

2.5.2.9. In the same way set the required width of the other columns;

 

 

2.5.2.10. Select the last column and in the field Auto Size specify the value 1-Yes - column size will vary depending on the free space of the screen;

 

 

Note: you can use auto size for any one or more columns.

 

2.5.2.11. In the fields Allow AdditionsAllow EditionsAllow Deletions select 1-Yes;

 

 

Note: the action Delete in ProjectDB program does not delete a record, but updates it's field Date & Time (Closed) with current time, after which the record is hidden. In such a way data is protected from accidental deleting. To display the record again dttmcl field in database table for this record should be updated with null value.

 

Deleting of records is possible if the field Date & Time (Closed) is set unspecified.

 

Thus there are two options for deleting:

- closing the record (if the field Date & Time (Closed) is specified);

- deleting the record (if specified field is blank).

 

Note: if you followed the steps 2.5.2.3 - 2.5.2.11, skip steps 2.5.2.12 - 2.5.2.17 and go to step 2.5.2.18.
