How to close another program with C#

If you are warking with winforms...
you can use the win32 api.

A week ago pareshgh showed me that the functions of the win32 api are availabe if you call the

using System.Runtime.InteropServices

you can

[DllImport("user32.dll")]

and from there I know from coding (in vb) that you can shut the computer).

If no one will give you a better solution I'll look the api code for you.

thans for help n please look up the code if thats convenient for u! :) i've searched in msdn for a while already but i couldnt find sumthin useful :S

I'm sorry that I don't have the time right now

but a quick search in google

gave me

http://www.mvps.org/vbnet/index.html...twindowsex.htm
first url

which looks real good

and this one is of microsoft (hope they know something about their OS ;)
second url
http://support.microsoft.com/default...NoWebContent=1

if you are trying to run the audio file.
herez the sample for you.
(the sample for playing the audio files
without any GUI)

u might consider running it in threads if u need

check the sample.
using
winmm.dll

[DllImport("winmm.dll")]

That's because you show the messagebox inside a loop. Do this in stead:

Code:

---

bool found = false;
foreach(Process p in pArry)
{
        string s = p.ProcessName;
        s = s.ToLower();
        if (s.CompareTo("wmplayer") ==0)
        {
        found = true;
        break;
        }
        else
        {
                //Do nothing
        }
}
if(!found)
{
MessageBox.Show("Windows Media Player is not running","",System.Windows.Forms.MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Information);
Application.Exit();
}

Try...

Code:

---

System.Diagnostics.Process[] _procs = System.Diagnostics.Process.GetProcessesByName("wmplayer");
if (_procs.Length != 0)
            MessageBox.Show("Media Player is running");
else
            MessageBox.Show("Media Player is not running");

---

Edit: Didn't see the second page either :blush:

the error is
An unhandled exception of type 'System.InvaildOperationException' occurred in system.dll

Additional information: Couldn't get process information from remote machine.

At this point it's pretty hard to understand what code you are trying.

Can you zip up and post a small project (minus the debug folders) so we can take a look at it?

here's the code

First of all, I suggest you upgrade from .Net 1.0. There have been significant upgrades since the 1.0 release (current is 3.5). You can also get express versions of Visual Studio 2005 or 2008 for free.

The problem with your 'Kill' code is that you are trying to compare the full path of an executable with it's process name.

For example, consider notepad:
Fullpath "C:\Windows\notepad.exe"
Process Name "notepad"

So the process killing code inside your sleep handler isn't going to find the notepad process.

Here's an alternative that works.

Code:

---

private void btnSleep_Click(object sender, System.EventArgs e)
{
        string processName = ExtractProcessName( ofdBrowse1.FileName );

        foreach( Process p in Process.GetProcesses( ) )
        {
                if( 0 == String.Compare( processName, p.ProcessName, true ) )
                {
                        p.Kill();
                }
        }
}

private string ExtractProcessName( string fileName )
{
        string processName = fileName;

        int index = processName.LastIndexOf( "\\" );

        if( -1 != index )
        {
                processName = processName.Substring( index + 1, processName.Length - index - 1 );
        }

        processName = processName.ToUpper( );
        processName = processName.Replace( ".EXE", "" );

        return processName;
}

---

Btw, Kill should only be used as a last resort. See the msdn docs for Process.Kill which recommends using CloseMainWindow to close processes.

private void btnSleep_Click(object sender, System.EventArgs e)
{
string processName = ExtractProcessName( ofdBrowse1.FileName );

foreach( Process p in Process.GetProcesses( ) )
{
if( 0 == String.Compare( processName, p.ProcessName, true ) )
{
p.Kill();
}
}
}

private string ExtractProcessName( string fileName )
{
string processName = fileName;

int index = processName.LastIndexOf( "\\" );

if( -1 != index )
{
processName = processName.Substring( index + 1, processName.Length - index - 1 );
}

processName = processName.ToUpper( );
processName = processName.Replace( ".EXE", "" );

return processName;
}





I have version 3.5 and i still get an error on
Process.GetProcesses( )

When you ask help from a programming forum, there are a few basics you need to know.

1) Describe the code
2) Describe the problem
3) Include any relevant code snippets
4) Include any specific errors

We can't help you if you don't tell us what the specific error message is.
