Hai sir! i am kannan please help me

insert, update, delete and search coding in VB.Net with access and sql? and way of connect and create access database using in vb.net?

Insert Query:

INSERT INTO table_name (column_names) VALUES (data_values)

Update Query:

UPDATE table_name
SET column_name = value
WHERE condition

Delete Query:
DELETE FROM MemberDetails WHERE condition;

Here is a simple code snippet for one of my apps. It searches, updates and deletes data. Maybe you can change the data and controls to suit your own app. Just take note of the 'updateMidwife' procedure which does the update function and the 'deleteMidwife' procedure which does the delete function. This is for sql-server
