Discrimanant taskkill.exe for excel.exe

Question

I have to run Excel on a server and to kill the excel.exe process I am using taskkill.exe:

System.Diagnostics.Process.Start("taskkill.exe", "-im excel.exe /f");

My only problem is that if there is someone who is also using the server who is working on excel (It could happen) then their processes will be killed also. Is there anyway around this to only kill the excel files created by my code? Any help would be great. Thanks!

Answer 1

Keep track of the PID of the processes you launch and kill them with taskkill.exe /pid NUMBER

Answer 2

If your able to get the PID using code (which I think you can) you can use the pid switch rather then the /im switch.

Answer 3

Microsoft says the following in this article.

Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

My suggestion is to use SpreadsheetGear for .NET which my company sells, or one of our competitors (just Google "SpreadsheetGear" and look at the AdWords to see who they are).
