hi this my code to change property from application setting (connection string)
i can't use my.settings.ConnectionString1= "some connectionstring" because it read only so i use my.settings.item()= ""
dim x= textbox1.text ' // like 127.0.0.1
My.Settings.Item("ConnectionString1") = "server=" & x & ";user id=root;password=root;port=3306;database=db1;charset=utf8;"
My.Settings.Save()
msgbox(my.settings.ConnectionString1) ' here change happen
Me.Close()
after close and open it the i found the value not change
i was solved it by declare new variable in "application setting" to store connection string every time changed, and copy it value to the main connection string variable every time loading form
