This application is not a client - server application. And also tell me, how would i know that application is running on another system or not ??? Thanks Devesh Mishra Re: How to communicate between two Dot Net application KKrista3-Jun-07 20:42 KKrista 3-Jun-07 20:42  Hi Devesh, One of the easiest way is to use a common file between the applications. The other way would be to use the config file and have some keys specific to each process. To know if ur application is running, u can search for ur application name in the Processes list of the machine where u have to search at. Regards, Murali Re: How to communicate between two Dot Net application devesh_code3-Jun-07 20:57 devesh_code 3-Jun-07 20:57  Hi Murali Thanks for ur reply. Would you tell me please, how to use config file between the applications and keys specific to each proces. Thanks Devesh Mishra Re: How to communicate between two Dot Net application KKrista3-Jun-07 21:03 KKrista 3-Jun-07 21:03  While developing ur application, in the app.config file, create a key (say 'instancenumber'). Then at runtime, set the key to a value (say '1','2',etc.) based on the instance of the application running. This will enable you to associate information specific to each instance.

I think that this solution will be easy. Or you can use Global Shared Memory, but if you choose this solution, you’ll work with P/Invoke (DllImport).

Bharath.S Ron Re: How to deal with reference variable in C#? KKrista3-Jun-07 20:47 KKrista 3-Jun-07 20:47  Reference variables are surely supported in C#. I think the problem under this case might be the use of variable without declaration. Regards, Murali Re: How to deal with reference variable in C#?

KKrista3-Jun-07 21:07 KKrista 3-Jun-07 21:07  While calling the method, pass the 'reference' variables as SomeMethod(ref varInput); Then in the definition of the Method u have to use the same reference variable as, public void SomeMethod(ref varInput) { //Give ur implementation here. } Regards, Murali Re: How to deal with reference variable in C#?

This is my code TimeSpan duration = startTime - stopTime; //to compute the difference between days, I use this code int result = (duration.Days); unfortunately it stops with duration.Days.. there are no available methods that will compute the months or years (eg. duration.Months , duration.Years) i tried to compute the days and divide it by 30, but this approach is highly innacurate. Hope you guys can help tnx Re: Getting The Difference Between Months Harini N K3-Jun-07 19:25 Harini N K 3-Jun-07 19:25  Hi Check this link http://www.c-sharpcorner.com/UploadFile/DipalChoksi/DateDiff_CS_DC09132006172429PM/DateDiff_CS_DC.aspx[^] Harini Re: Getting The Difference Between Months zoroyster3-Jun-07 21:30 zoroyster 3-Jun-07 21:30  Hi harini.
