Detecting that a program is already running

[Joecx]

Hi
Does anyone have the code or maybe give me a start on how to detect if my
program is already running if someone tries to run it again while it's already
running? I know I could do this with a dummy file by putting something in the
file while it's running and emptying the file when it's not running, but I was
hoping for something a little more professional. Has anyone done this yet?

Hi Joe,

You can try this code

' Imports System.Diagnostics.

Dim p As Process
For Each p In Process.GetProcesses
lstProcesses.Items.Add(p)
Next

you get a list of process running in the machine may be you can check your
program in the list of process and
if its there then its running else not !

Hope this helps you

Thanks

if there is a .net solution...

In VB6 I used:

http://internettrash.com/users/fdb/already.htm

If App.PrevInstance = True Then
MsgBox("The program is already running!")
End
End If

Maybe there's an equivalent in c#

Ok, wait.

I guess this guy has the answer:

7> Now Paste the following snippet right after the Main functions
starts before the existing line.

Process aProcess = Process.GetCurrentProcess();
string aProcName = aProcess.ProcessName;

if (Process.GetProcessesByName(aProcName).Length > 1)
{
MessageBox.Show("The application is already
running!!","Test",MessageBoxButtons.OK,MessageBoxI con.Stop);
Application.ExitThread();
}

That's not a terribly *good* answer though - it fails if anyone happens
to use the same process name. I gave you a link to a better answer in
my previous post though.
