The code works fine If I Dont use Identity Column, But I need to use Identity Column in my Project :( ...Please Help.
 
Dim cmCustomers As New SqlCommand("INSERT INTO Customers VALUES ('',' " & TxtName.Text & "','" & txtAdd.Text & "','" & txtState.Text & "','" & txtZip.Text & "','" & txtPhone.Text & "','" & TxtEmail.Text & "')", cnNWind)

is where your problem is... but not specifying what columns to insert into, it assumes insert something into all.. you need to explicity say:

INSERT INTO Table (Col1, col2, Col3, col4...etc) VALUES (.......

of course not including the id coumn
