A tag already exists with the provided branch name. There are plenty of articles around that will show you how to do this. Organize these into server groups, where all servers in a group should operate in unison; that is, since each server group is bound to a single context menu entry they all are enabled or all disabled together. If you enjoy, and learn best by, following the whole process of how a particular system tray application was designed and built, then read on! The Red-Headed League, A. Conan Doyle.

How can I make a .NET Windows Forms application that only runs in the System Tray? Lets say you have a simple Hello World NW.js app, and youd like to give it a tray icon to access it from the OSs main bar. You should use the code shown here as a template for your own child forms, changing the one line that indicates the Form name and optionally, its arguments. Why does sending via a UdpClient cause subsequent receiving to fail? Not the answer you're looking for? Observe how these come directly from the hosts file. Similarly, when it disables a server group it comments out the respective lines in the hosts file. It follows, therefore, if you need to have corrupt entries (as far as HostSwitcher is concerned) for performing other tasks on your computer, when you want to come back to HostSwitcher just select your target server group and you are ready to go. (By the time it opens, the code in the event handler should have populated it, of course.). Each meta-comment indicates a project/server group pair in brackets with a virgule separating them.

You can freely use the code to create another system tray application. You can adjust the properties easily, though. When it enables one server group it just uncomments the lines of the host file containing the servers in that group. How can a Metro app in Windows 8 communicate with a backend desktop app on the same machine? Now let add a Double Click event on the NotifyIcon. Also, it lends itself to learning by trying out examples. The key to applying best practices to designing a tray application is shifting your perspective to a tray-centric focus: instead of thinking of your form (be it WinForms or WPF) as the master controller of your application, think of the little tiny tray icon as the master controller. Since these are comments, they are completely transparent to other consumers of the hosts file. > Features > Windows System Tray Application Windows System Tray Application The Windows System Tray Application provides a self-service tool for the end user. The next step is to create menu items for each of our functions: We use two properties of the newly created menu items; Name and Text. I wanted a simple, easy, and fast way to do that automatically. Note that the all-encompassing error trapping is important here-you want to ensure that you release the mutex even if your program throws an exception. Remember the cardinal rule of server groups within a project: they are mutually exclusive. As I was experimenting with the form-centric approach I found one significant deficiency: it is challenging to start an application in the tray. The System Tray features different types of notifications and alerts from your computer like your Internet connection, or the volume level. The app, from the icon in the system tray, must be able to open a WinForms or WPF window as needed. Click on the Search Bar. Find centralized, trusted content and collaborate around the technologies you use most. (Do this in a new, separate project because Visual Studio does not let you put a WPF window in a WinForms project. Is it possible to make a high-side PNP switch circuit active-low with less than 3 BJTs? Because the Hosts file in Windows is in a protected, system directory you must have administrative privileges to run HostSwitcher. Developing a simple Windows system tray desktop app to consume a .NET web service, http://www.codeproject.com/Articles/36468/WPF-NotifyIcon, Going from engineer to entrepreneur takes more than just good code (Ep.

The HostSwitcher icon itself has these features: Double-clicking the icon in the system tray re-opens the introduction/help page. Did the words "come" and "home" historically rhyme? This article explained the implementation of the system tray application in the GitHub repository. Here's one to get you started: http://www.codeproject.com/Articles/290013/Formless-System-Tray-Application. Each developer on the project has to do this same silly procedure. Add a NotifyIcon to the main form. What do you call a reply or comment that shows great quick wit? The system tray app will show (in a context menu) a counter of notifications of new events as received from the .NET web service; and will also write all the event logs into a text file. With that in hand you then use this slightly different method to display the form: The only difference from the WinForms version, discounting names, is the additional line invoking the EnableModelessKeyboardInterop method. Step 1 Go to the SETTINGS window and choose System.

About the only thing I could not come to a good resolution when designing this application is its name. You may also have required a console application for special needs such as batch processing or automated workflow.

Scroll until you find HostSwitcher and change its setting from Only show notifications to Show icon and notifications (top, Figure 3) to migrate the icon down to the main tray (bottom right, Figure 3). Open Program.cs - remove the line that reads Application.Run (new Form1 ());. That way, if you do edit it externally it will pick up on your most current changes. But for a tray-centric application like HostSwitcher there is little benefit-the application is in the system tray so there is not even a concept of bringing it to the foreground. Each time you open HostSwitchers context menu it rereads the hosts file. Why should you not leave the inputs of unused gates floating with 74LS series logic? This is his code sample: This technique uses the .NET Mutex (short for mutual exclusion) synchronization primitive. For a form-centric application, re-activating the first instance when the user attempts to launch a second instance is clearly a good usability goal. Step 2 In the SYSTEM window, select Notifications & actions.

I have a solution in mind to strength the Mutex approach (though I have not yet implemented it): use the standard Mutex for enforcing a single instance, but then use the process table technique to find the first instance and activate it as demonstrated in the code sample above. I'm required to develop a simple Windows system tray desktop app to consume a .NET web service but I'm proficient in PHP, and I have little background in desktop applications.
