Running Window Application using Window Service
How to run window apllication in specfic interval from window service
1)Create window service application(Assume Creation of window service known)
2)Use Namespace system .Timer add timer.start in start method of windowservice
3)Add Time elapsed event handler mechanism in start method of window service
4)In Timeelapsed event add following line code
Process proc;
proc = new Process();
proc.StartInfo.FileName = @"C:\windowapplicationName.exe";
proc.StartInfo.Arguments = "jhgj";[optional]
proc.StartInfo.WindowStyle = ProcessWindowStyle.Maximized;
proc.Start();
5)After install service in service controler right click on service name
then click properties under login tab enable Allow service to interact with desktop (For Automatic enable review code given below add name space Microsoft.win32 in code)
6)Start service
