Check if app is already running?


Check if app is already running? Dan

dotnet compact framework:
Can anyone point me in the right direction to check if the application is
already running for a .NET CF 2.0 application?

Code for the regular .NET framework does not work because it uses
process.GetCurrentProcess.MainWindowHandle

which is not supported in the CF.

You need to P/Invoke CreateToolhelp32Snapshot, Process32First and
Process32Next .
you can also use OpenNetCF.org and use the OpenNETCF.Toolhelp namespace.

Hope this helps

For your own process just create a named system mutex (P/Invoke CreateMutex
or use the OpenNETCF.Threading.NamedMutex). On startup, create and hold it.
If it already exists at that point, you know another instance is running.
