Forms :: Create A System Tray Application (service)?
Feb 16, 2009
I'm wanting to develop what I perceive to be a pretty simple application. I want something that runs in the system tray that tests for the presence of a particular file on a network drive. If the file does not exist, the icon in the system tray is a green circle (like a traffic light).If the file DOES exist, then the system tray icon is a yellow circle (caution), until the user clicks it (the yellow system tray icon), and a record is written to another file, then the system tray icon changes to a red (stop) circle until that first file we tested for is gone.I'd also like to create "balloon messages" to go with the changes in the system tray icon.

I've seen loads of programs that use an icon in the system tray to let you interact with a windows service that is running on your machine but I am curious as to how this works. As I understand it, unless a service marks itself as 'interactive' then it has no way to communicate with the user's desktop and doing so is discouraged by MS (and even causes an alternate desktop to appear temporarily in Server 2008 in some cases). So I want to try and avoid doing this but I cant think how else I would do it, and even if I marked my service as interactive I'm not too sure how I could actually get it to show a notification icon in the system tray.
I assume I would have to use Windows APIs, unless just using the windows forms NotifyIcon class would work. I considered just having the system tray icon in a totally separate application that just communicates with the service via named pipes or TCP etc but I'm pretty sure this isnt how other programs do it because with most of them if you just kill the process that the service is running in then the icon disappears so it must actually be directly running from the service.

how to create a contextmenu for system tray icon vb? Where can I find an example of it? I am building a service with a system tray icon to start pause and stop it however I don't seem to be able to display the contextmenu on click event. Do I need a form for the context menu?

how to create the contextmenu near the system tray icon that i've created? the current contextmenu will always "run" to certain position. How to do that? especially the second parameter of the following:
Me.contextMenu1 = New System.Windows.Forms.ContextMenu
Me.menuItem1 = New System.Windows.Forms.MenuItem
Me.menuItem2 = New System.Windows.Forms.MenuItem
Initialize contextMenu1
[Code]...
Me.contextMenu1.Show(Button1, New Point(0, 0)) .NET not allow the control to be the notifyicon, so i added a button.hOW to make sure that the contextmenu always firm on one position , ie, at the system tray icon that i've created. Once i click on the icon, it will show this contextmenu.

I need a clue where to start: how to create an icon that will show up at bottom right of explorer bar.. maybe I don't what its called. I guess windows named that "system tray icon".

I'm having trouble figuring out how to access my system tray context menu from a winforms opened up from one of the menu choices. The task notifier was created using a module and an applicationcontext so I could start the application without a form.
Here is m simplified code.
Module Module1
Public OpenFormsHash As New Hashtable
Public Sub Main()
[Code]....
When I start my form, in this case fSettings, I can't figure out how to get access back to my context menu. I'd like to modify it based on events that happen on the open form (fSettings).

I am trying to create an icon in the system tray as status for num-lock, caps-lock, and scroll-lock, because my keyboard that came with my computer does not have status lights on the keyboard, and only on the system tray.
The program however that came with it, does not like to work when I have some games open and stuff, it works usually in IE, and most other programs, but some programs just seem to interfere with it.
I have made a new program on a 1 mili-second timer for the 3 and it seems to work just fine in the application, I was wondering now if I could move that over to the system tray and make it look like the one that came with computer, it has 3 different icons, and the icon changes for on/off and has a tooltip status change on mouse-over showing status of on/off.

I have a vb.net program created in VS2008, winforms/desktop application. I have it on a timer event so that every 4 hours it rins some actions. When I minimize the application ot the system tray...after a seemingly random period of time....it will not maximize. It acts frozen however the program still runs and the timer events usually fire on time. I just can't get the main form back up to see the menus and interface with the program. I have tried doevents, refresh, getfocus etc... nothing seems to make it refresh.

I am having an applciation running in system tray notification area, but the problem is that although I exit the application the icon is still there, when I point my mouse near notification area it's gone as it should be when I clicked on exit. I guess it is because my mouse position makes the area to refresh, if so, how can I do it inside my application to avoid having my useless icon in there?

my program has a tray icon and i want it to show up in the system tray. so i went into my windows notification area and set it to show icon for my app. But when my app update to a new version with clickonce, it will think its a new app and i have to set it again. Is there a way that it will treat all new version as the same program and i dont have to keep setting it?

This is what I'm trying to accomplish: I have a Point of Sale application that integrates with a credit card processesor. I wan't to remove any user interfacing logic in regards to the credit card processor in the point of sale and add it to a application that sits in the background or system tray. I want to be able to send a command to the background app to popup a form for user input.
For example: User in the Point of Sale clicks a button "Credit Card" at this point it will send a command to the background app say "ProcessCC" which will pass a transactionid and an amount , this will open a form for the user to enter in the credit card information and submit the payment to the credit card proccessor.
Reason: I need to get a padss certification and don't want to submit the point of sale to do it. Rather send the simple background app that will control any credit card processing functionality such as encryption , storing etc. I know it can be done using sockets but was hopping for an alternative solution.

We run a CRM package and one of the features that it lacks is the ability to Date and Time Stamp when someone updates an activity. I was wondering if it would be possible to write a vb.net application that would start minimized to the system tray and then assign a hotkey to this app, for example CTRL Shift and K, that would paste a date time stamp into what ever application was focused at the time.

one of the apps that I wrote a couple months ago is getting to be rolled out to my production floor; one issue tho - It works great as a standard executable (you double-click, it starts and waits for data), however, I cannot get it to start as a system service.
I've already done a little bit of research for how to create a system service, but most of the information that I've come across is point to VC# or Visual Studio 2010 - I'm not finding much for VB 2010. Additionally, I'm only using VB 2010 Express and I'm pretty sure that I don't have the Windows Service application template's on my PC.
My application does have a "UI", but there isn't any user interaction; it starts and just sits minimized in the system tray polling a directory for the existence of a file - i.e. the windows form is not required.

I have a web service that I'd like to include as a project reference inside a windows forms application. (The application will be running on non-networked hardware.) I could simply copy the *.vb files I need into my forms project, but I'd rather not fork the code base.It wasn't hard to include the ASP project in the windows forms solution. However, I can't figure out how to reference it in my forms code.

I have an application that I created a while ago. It's a forms based application that runs on one of our servers at work. The app works well, BUT at the moment, requires someone to manually run it, which means having the admin account always logged in, but having the server locked.Although it's a forms based application, for the majority of the time I don't need to see the forms, so can I safely make this run as a service (by adding the appropriate code), and hiding the forms?Also, is there some code I can put in to test whether the instance of the program was started as a service or from a user double clicking on the icon? If so, I'd like the user initiated instance to run with the forms visible.

I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I im trying to find out if it's possible (using VB.net 08 Xpress) to create an application running solely out of the system tray, no forms - Just the icon and popup notifications.I have been considering building a tray based monitoring system for some time, and while I can get the code to work fine, I still need the thing to start up silently. Using Me.Hide() on Form load doesn't work, and I really don't want to work around using the start-up form as a splash page.I have also looked at making a module, but standard vb.net code just aint doing the job.

I have a problem: I have got an application that is mainly control by a tray icon and I can't show the window unless I click the icon, but the client computer has set the system not to show the icons in the tray area. So can I write a small app to act like a hand-make system tray? That means I have to get all the icons in the tray area and be able to send the mouse events to the icons and let them response to their own program.
