Hi Thom,

Based on my understanding, you want to un-install an application, so you
want to know whether an application is running before un-install.

=============== =============== ==
You can refer to System.Diagnost ics namespace.

You can use Process.GetProc essesByName method to return a list of running
processes, whoes name is your application.

If you can not determine your application's name, I think you may use
Process.GetProc esses method to get all the processes current running. Then
for each process, you may use Process.MainMod ule.FileName to get the
process's main module's full file path.(You can compare this with your
application's path to determine if it is your application's process)

=============== =============== =
Please apply my suggestion above and let me know if it helps resolve your
problem.

Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.

You unfortunately answered the question I asked and not the question I
thought I asked ...

Is there a way to shutdown the running task after you have identified it or
are you restricted to "tell the user to shut it down and exit the
uninstall"?

My assumption is that there is no way to shut it down.

Hi Thom,

Thanks very much for your feedback.

If you have determined the process is running now, the normal way is notify
the user that the application is going to be un-installed, and letting the
user to close it properly.

You also may use Process.Kill method to terminate it yourself, but data
edited by the process or resources allocated to the process can be lost. So
it is not recommanded to use this way.

All in all, you should use your second option.

Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.

It ALMOST does. What came up with was ...

using System ;
using System.Windows. Forms ;
using System.Diagnost ics ;

namespace ThomLittleAssoc iates
{
public class tlaSystemTrayDe tect
{
public static void Main( string[] args )
{
for ( ; ; )
{
Process[] procMain = Process.GetProc essesByName(
"tlaSystemT ray" );
if ( procMain.Length > 0 )
MessageBox.Show ( "Your system is currently running
tlaSystemTray.\ nRight-clicktlaSystemT ray and select Exit.\nThen respond OK
to this message.", "tlaSystemT ray" );
else
break ;
}
}
}
}

.... and this works fine when added as a custom action to uninstall.

The only problem is that it displays an empty command line window as it
runs.

My NEXT dumb question is how do I get rid of the bogus command line window?

I found it ...

I needed to change the Output Type for this class to Windows Application.

The uninstall is now running correctly and it will sit in the loop waiting
for all occurrences of the application to be removed.

It is really strange that two standard dialogs are not present in the MSI
....

1. Start this application after installation.
2. Shut down this application if running during uninstall.

Hi Thom,

I think the dialog for "Shut down this application if running during
uninstall" does exisit but the wording is a little bit different.

The dialogs in MSI are quite different from the dialogs in WinForm
applications. We have the option to author our customized MSI dialogs,
either through VS.Net Setup project, or through Windows Installer Platform
SDK.

If you need any further assistance on MSI issues, please feel free to post
under "microsoft.publ ic.platformsdk. msi".

I searched rather aggressively with no luck. If dialogs for ...

1. Start this application after installation.
2. Shut down this application if running during uninstall.

.... exist in the MSI their location is the best kept secret in Visual Studio
..NET 2003.

Do you have a suggested information source?

Hi Thom,

Thanks for your update. The "2. Shut down this application if running
during uninstall." dialog is not shown in VS.Net. If we open the MSI
generated by Setup project with Windows Installer Platform SDK tool "Orca",
we can see there is a dialog named "FilesInUse ", which contains the
following "Text" control:

The following applications are using files which the installer must update.
You can either close the applications and click "Try Again", or click
"Continue" so that the installer continues the installation, and replaces
these files when your system restarts.
