What is the C# command/function for checking to see if another instance of
the application is already running?

Rob,

I assume you are looking to only have one instance of your app running
at the same time. In order to do this, check out a previous response to
this question:

Hope this helps.

Use a mutex like this:

...
bool firstInstance;
using (Mutex AppMutex = new Mutex(true, new
Guid("xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx").ToString(), out firstInstance))
{
if (firstInstance== true)
{
// run your code from here
}
} // mutex released here.
...
