I've seen all the answers for the standard framework What is the correct way to create a single instance application? Prevent multiple instances of a given app in .NET? What is the best way to make a single instance application in .net? How do I check whether another process with the same name exists using the compact framework? The 3 parameter constructor is not supported by the CF Process GetProcessByName is not supported by the CF OpenNETCF gives you class OpenNETCF.Threading.NamedMutex that let's you create system-wide named mutex. http://www.opennetcf.com/library/sdf/html/40db385b-e21b

I want to check when the user double click on applictaion icon that no another instance of this application is already running. I read about My.Application but i still don't know what to do. Pete OHanlon The most common pattern for doing this is to use the Singleton pattern. As you haven't indicated a language, I'm going to assume that you are referring to C# here - if not, the principles are still the same in most OO languages. This article should give you some help. This is something I've used... (C# on .NET 2.0) [STAThread] private static void Main(string[] args) { //this follows best

I'm trying to create an application which only allows a single instance across all Windows users. I'm currently doing it by opening a file to write and leaving it open. Is this method safe? Do you know of an alternative method using C? The standard solution is to create a global mutex during application startup. The first time that the app is started, this will succeed. On subsequent attempts, it will fail, and that is your clue to halt and fail to load the second instance. You create mutexes in Windows by calling the CreateMutex function . As the linked documentation indicates, prefixing the

I have a program that works when, a file is opened with it using the right click menu in explorer. But if I select multiple files and then right click and open with my program then it opens multiple instances of my program, instead of just passing the multiple files as arguments to a single instance. The program is written in vb.net but is not a windows form, it is just a module, so I can to tick the Single instance option in the properties in Visual Studio. So how do I open multiple files from explorer context menu in a single instance. No happy answers here, Windows Explorer doesn't provide
