Mr. Bill, If the load is not so much, I think you right. My program will call WebServices continuously. If demands are much, I may run the same program more than one in the server. If I use timer event, I don't sure what should be the intervals. More interval means client wait more, short intervals may decrease the capture of stop button click event. I mean when user click the stop button, if program in job, will not reponse. Isn't it?

Wouldn't it be better to put the test into a timer event, so it doesn't waste resources? I haven't implemented your appoach anywhere, but can see it's usefulness. I'd just like not to eat a lot of resources when in this mode, which potentially can go on for some time. Also, I am assuming that timer-driven events are a hardware (clock) thing and not a loop somewhere within VFP's runtime, in which case it doesn't matter as much. I believe this question has come up before, but don't think I got a clear understanding of it: do timer events eat any resources while waiting to fire?
