"error: operator '&' not defined types 'string' , 'system.windows.forms.textbox'."

i don't know error in both save , update buttons.

the answer easy:

you didn't call text-property every time used textbox value.

look @ txtcity variable:

"'and city = '" & txtcity & "'"

should be

"'and city = '" & txtcity.text & "'"
