The objective of the Project Planner application is to facilitate project and employee management in an organization. It is a form-based Windows application that uses the TabControl for segregating the project management and employee management activities. The main form of the Project Planner application has two tabs: Employee and Project.

Form1.cs [Design]The following fi gures show the Employee and Project tabs in the Design view:

Backend DatabaseAs shown in the above fi gures, the Project Planner application uses a number of fi elds for recording employee and project related information. Thus, a backend database must be created for recording this information. The Project Planner application uses Microsoft Access as the backend database. The following fi gures show a snapshot of tables, Table 1 and Table 2, created in MS Access for storing Employee and Project related information:

Linking Data SourcesAs we can see in the Design view, both Employee and Project tabs use the DataGridView control for displaying the records submitted by the user. To populate the DataGridView from a backend data source, it must be linked with the corresponding data source. The following are the steps for linking DataGridView control with a data source: 1. Select the DataGridView control and open the DataGridView Tasks pane, as shown below: 2. Select the Add Project Data Source option from Choose Data Source list to initiate the Data

Source Confi guration Wizard, as shown below: 3. Select the Database option and click Next to display the Choose Your Data Connection

screen, as shown below: 4. Click the New Connection button to display the Add Connection dialog box, as shown

Adding INSERT QueryThe above code uses the Update method for posting records into the database. Thus, an appropriate SQL Insert query is required to be created, as shown in the following steps: 1. Open the DBDataSet.xsd fi le and select Data → Add → Query to initiate the TableAdapter

Query Confi guration Wizard, as shown below: 2. Click Next to display the Choose a Command Type screen, as shown below: 3. Click Next to display the Choose a Query Type screen, as shown below: 4. Select the INSERT option and click Next. The SQL INSERT query will automatically get

created. Click Finish to close the TableAdapter Query Confi guration Wizard.This completes the development of the Project Planner application.
