Starting an application on the server
-
Is it really possible to start a program that resides in the server from a web application? I am using following code:
using System.Diagnostics; Process startNotepad = new Process(); startNotepad.StartInfo.FileName = "notepad.exe"; startNotepad.StartInfo.UseShellExecute = true; startNotepad.StartInfo.CreateNoWindow = false; startNotepad.Start();This works while debugging the page. I can see notepad start. But when I try it in a server I dont see Notepad, but I do see a process in task manager started -

ASPNET does not have an active desktop, thus, the process will run but will not display.

Does that mean I could run an application (.exe) in the background (say one without a user interface) that I upload to my server using this method? Say, for example, one that sends out emails to a list I upload... How about one that wipes the server hard-disk.. eek... Fred

If ASPNET's access is more than its default access, you are opening up your web server to some nasty security issues. There are more secure ways of doing running a process.

It is possible but not advisable.

Yes, it can be a security issue. Also, you loose a lot of control of your application since you are running mulitple processes. Since your web application may have several user using your application at the same time, running several of the same local processes can be come a resource hog or cause some unforeseen conflicts. If a local process fails, how do you recover?
