The code inside the timer1.tick event handler is going to run every time the set interval is reached. For instance, if the interval is set to 1000 then that code will run every second. You will probably need a signal to enable and disable the timer or a conditional so that the code only runs when you want.

i did wan it to run i waned when i login the time will reord the time what time i login
but when i key in the password it auto come out alot of box

how to do it?

Instead of of a timer use an event handler of the textbox where you enter the password. One possibility is the keypress event and have the user press enter.
