The script is as follows and you will need to input the details relevant to your environment

dim connectstr as string;

dim SQLConn as System.Data.SqlClient.SqlConnection;

dim SQLCmd as System.Data.SqlClient.SqlCommand;

dim SQLRdr as System.Data.SqlClient.SqlDataReader;

dim sQuery as string;

 

ConnectStr = "Server=" + "machine name"+ ";Database=" + "SQL Database name" + ";UID=" + "sql username" + ";PWD=" + "password" + ";";

SQLConn = new System.Data.SqlClient.SqlConnection(ConnectStr);

SQLConn.Open();

 

sQuery = "SELECT [Employee]";

sQuery = sQuery + "FROM [EmployeeTable]";

 

SQLCmd = New System.Data.SqlClient.SqlCommand(sQuery, SQLConn);

 

SQLRdr = SQLCmd.ExecuteReader();

While SQLRdr.Read()

EmployeeName = SQLRdr("Employee");

ComboBox1.AddItem(EmployeeName);

endwhile;

SQLRdr.Close();

SQLConn.Close();

 

4 Right Click on the canvas and select Custom Property. Create a Custom Property String called EmployeeName then click OK button. This populates the the Combo Box with the names obtained from the database column.
