Hi, I'm having a bit of hassle with regard to using the timer interval property.I want my code to go off and check the systime every hour, but can only use the timer interval property to execute my code after a maximum time of 1 min. This however is too frequent and it also uses up to much cpu time, is there any way for example of executing this do loop while the form is open without using the timer function? any help would be appreciated...
