Process.Start

 

hello,

 

i see process.start command; way of figuring out when process ends?  there callback can't find?  have kick of series of processes in order, , need 1 end, next 1 begins, etc.

 

thanks.

here 2 methods wrote in c#.net figure out when process ends. need know process name or @ least part of process name, depending on method use. hope helps.
