How to find the time interval of a windows service in asp.net with c#?
Code as follows:
Process p=new Process()

p.StartInfo.FileName = @"D:\C3sps  Project\COMMON\Source\Untested\C3psps\C3PSPS_EOD\bin\Debug\C3PSPS_EOD.exe";
                           p.Start();

With service I am able to update. But only after a certain time interval.
