Killing a Server Process from a ASPX web page.

[DigitalMyth]

I'm designing a game server managment system. I need to know if you can end a process "MOHAA_spearhead_server.exe" on the server by using a ASP.NET command or is another program is needed that can receive commands from the web page.

download ASPExec from:
http://www.serverobjects.com/products.htm#free

Register it in component services, make sure you run the component as an admin on the server so you don't run into an permissions issues.

Create a batch file to kill the process, most likely:

tskill PROCESSNAMEHERE

Add the ASPExec DLL to your ASP.NET project. .NET should automatically create the interop for the file.

Your code:

Try
     Dim p As New AspExec.Execute
     p.Application = "cmd.exe"
     p.Parameters = "/c INSERTFILENAME.bat" 
     p.ShowWindow = False
     p.ExecuteWinApp()
     p = Nothing
Catch ex As Exception
     Throw
End Try

I know it sounds like a lot of work for something that seems simple, but it is the easiest way i have found to get this accomplished.

I also recommend you do not bother with the System.Diagnostics class dealing with processes and such, you will only be wasting your time.

If the tskill command doesn't work, which it may not if you are using windows 2000 server or running it from a os like Windows 2000 or windows XP then instead download PSTOOLS:
http://www.snapfiles.com/get/pstools.html

Extract the zip and place the files in a directory of your choosing.
In the batch file:

cd \
cd pstoolsdirectory
pskill PROCESSNAMEHERE

The rest of the code and such is all the same.

I hope this helps or gives you a really good idea of what to do.

Here's something you could try:

Function KillProcess(ByVal sProcessName As String) As Boolean
    Try 
        Dim localProcesses As Process() = Process.GetProcessesByName("MOHAA_spearhead_server.exe")
        If localProcesses.Length <> 0 Then
            Dim i As Integer
            For i = 0 To (localProcesses.Length - 1)
                Try 
                    localProcesses(i).Kill
                Catch
                    'Process is already unloaded or
                    'the assembly doesn't have sufficient security permissions
                    'for this method.
                End Try
            Next
        End If
    Catch ex As Exception
        'Log the exception somewhere.
    End Try
End Function

If you are really brave you could use api.....

This involves marshalling or even worse managed c++

#include <windows.h>

#using <mscorlib.dll>

//will most likely not work......
//compiles though.....
namespace JustAnExample
{
	public __gc class KillProc
	{
		public:
			static void KillDie(System::IntPtr* hProc);	
	};
}

void JustAnExample::KillProc::KillDie(System::IntPtr* hProc)
{
	TerminateProcess(((HANDLE)(hProc->ToInt32())), 0);
}

this might help some

what namespace is that process object in?
