This document describes creating a Visual Basic database management system to store and manage land area coordinate data. It includes: 1) Creating an MS Access database called "LandArea" with tables to store point ID, longitude, latitude, and land ID fields. 2) Developing a Visual Basic interface connected to the Access database using ADO, with controls to add, edit, delete, view, and select coordinate data and lands. 3) Programming buttons to perform tasks like saving, editing, updating, clearing data as well as moving between and drawing outlines of lands based on their coordinates.
![ Question:
Create visual basic project to draw the outline of a land area of land using longitudes and
latitude values. Assume that you can use MS Access data base to store the coordinates,
Table:-
Point ID
Longitudes
Latitude
Land ID
Your project should do the followings:-
Enter new coordinate
Edit the coordinate
Delete unnecessary coordinate
List OR View all coordinate
List OR View all coordinate of the selected land
Draw outline of the land
Draw outline of the select land
Use the following object in your project:-
Connection object
Record set object
Commend object

- 3. Creating Data Base using MS Access 1) Starting access methods Start programes Microsoft Office Access Double click desktop microsoft Access Icon 2) In the temple window select BLANK DATABASE and then enter database name as “LANDAREA” finally click create button. Then “LANDAREA” database window appears with in MS Access window. 3) When you select CREATE > Table Design.A table design window appears. Enter your field name,data type and size.finally save the table Create the following tables on MS Access and save it on database name “ LandArea ” Data Base Design view Data Base view Field Data Type Size Point ID Number Integer Longitude Number Long Integer Latitude Number Long Integer Land ID Number Integer
- 4. Saving Data Base in MS Access Vissual basic 6.0 to connect the database in MS Access must important the Access 2002–2003 Database formate and “ _ _ .mdb” file type Creating programme using Visual Basic 1) Open Vissual Basic 6.0 2) Select the “Standard EXE” and then click open botton 3) In visual basic screen , go to “PROJECT” tap then click “REFFRENCE” then select “Microsoft ActiveX Data Objects Recordset 6.0 Library” then click “OK” Button.
- 5. Database is located at …… So, the path of the database is C:landarea.mdb Easy to work we add ADO control and View all cordinate at the time we used DataGrid 1) In visual basic screen , right click the toolbox menu then goto “components” then select “Microsoft ADO Data Control 6.0 (OLEDB)” then click “OK” Button again goto “components” then select “Microsoft Data Grid Control 6.0 (OLEDB)” then click “OK” Button . 1 2 3
