cmd.commandtext = "update user_master set uname = " & """" & txtuname.text & """" & _                         " , password = " & """" & txtupass.password & """" & _                         " , creation_date = " & """" & date_gl & """" & _                         " , creation_time = " & """" & time_gl & """" & _                         " , permission_id = " & _user_perm & _                         " , zone_id = " & _zone_id & _                         " id = " & _usr_id_temp                     cmd.executenonquery()

i hope right help.

thank you, abhimoh

i suppose previous answer using ms-access , oledb update database.
if case password reserved keyword , need encapsulate square bracket. use parameterized query avoid parsing problems of text, decimals , dates , of course prevent sql injections 

cmd.commandtext = "update user_master set uname = ?" & _                    " , [password] = ?" & _                    " , creation_date = ?" & _                    " , creation_time = ?" & _                    " , permission_id = ?" & _                    " , zone_id = ? & _                    " id = ?" cmd.parameters.addwithvalue("@p1",txtuname.text) cmd.parameters.addwithvalue("@p2",txtupass.password) cmd.parameters.addwithvalue("@p3",date_gl) cmd.parameters.addwithvalue("@p4",time_gl) cmd.parameters.addwithvalue("@p5",_user_perm) cmd.parameters.addwithvalue("@p6",_zone_id) cmd.parameters.addwithvalue("@p7",_usr_id_temp) cmd.executenonquery()
