[RESOLVED] [2005] Keep two copies of application from running at same time

Does anyone have any sample code that makes it to where only one copy of an application can be open at one time? For instance, if I open my .exe now, it opens my application. If I double click it again, it opens another instance. How can I keep it from doing this?

There is a property on the project properties that is "Make Single Instance Application". Check that and you should be good to go.

Thanks!
