Time Management System

In this article, you will learn about making a time management system which is developed using VB 6 and MS Access.

The system helps to do two simple task – Add new activity and View Activities based on following criteria.

  • Important and Urgent
  • Important and Not Urgent
  • Not Important and Urgent
  • Not Important and Not Urgent

The resultant view is based on the criteria selected.

System Diagram

The system diagram for time management has only three forms and a database. The added activity requires activity id, start date, end date, title and description for each activity. Also, you need to specify the criteria for each activity mentioned above.

ER Diagram for Time Management System

The ER diagram contains the entity set and their relationship. The diagram contains a single entity – Activity.

The ER model will be converted into a relational model, discussed in the next section.

Relational Model and Table

The relational model is another representation of the ER model shown above. It is used to describe a schema for a relation or table.

Using the relational model we will make a table for our project. All the information regarding activities will be stored in a single table in the time management system.

Database and Table Creation

Our database for the project is created in MS Access. If you do not have MS Access then install any version above MS Access 2000. Create a new directory and call it AccessDB and also create a 2000-2003 database file and save it as a .mdb.

Open the .mdb database and go to Design View, a Save as dialog box will ask the name of the table, type Activity. You can create field name and data type as per the following diagram.

Now that the database design is complete, we must start the form design and coding in VB 6.

Form Design And Coding

The time management system has 3 forms and one module for database connectivity. In this section, we will discuss about designing the forms and coding for the controls that belong to each form.

  • Time Management System (frmTimeManagement)
  • Activity Management (frmActivityManagement)
  • View Schedule (frmViewSchedule)

The time management system is the main screen and the entry point for the software. Activity management is where we manage activities. A user can :

  • Add a new activity.
  • Delete an activity.
  • Modify an activity.
  • View schedule based on importance and priority of the activities.

Module For Database Connectivity

A separate module is required to establish a connection with the database. This will enable access to the database and run query on it. In our project, the database is accessDB.mdb or the name you gave to your database earlier.

To create a module, go to Project Explorer > [right click] Modules < [mouse over] Add > [click] Module.

Create a module in Project Explorer
Create a module in Project Explorer

Add following code to the new module.

Public con As New ADODB.Connection
 Public rs As New ADODB.Recordset
 Public constr As String
 Public Sub loadcon()
 constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\AccessDB\ActivityDB.mdb;Persist Security Info=False"
 con.Open constr
 End Sub

Note: The"C:\AccessDB\ActivityDB.mdb" is the path to the database location. In your case, it might be different depending on where you store the MS access database file.
