I have created a windows service to perform certain task on regular basis. Now I want users to change few parameters by themselves. So user should be able to right click on the service and click on settings and a form should appear. On save button all the values should be saved to the app.exe.config file.
Does anyone have any tutorial or any reference website?
1) Users NEVER right click on a Windows Service. WS are by definition programs that run in background.
2) You can create a service controller, a windows form application that interacts with the service and sends commands like pause, start, stop, etc. Implement your user interface in such controller.

I would like to display toast notifications in windows from my WinForms application. I am using the ToastNotificationsManager class from DevExpress to manage the process. When the ToastNotificationsManager is initialized, its "ApplicationID" property has a GUID set to it, and because a shortcut in the start menu is required for the notifications to work, I click "Create Shortcut" in the smart tag to create one.
It appears to me like that ID is used in the .lnk shortcut file and that's how the application knows which shortcut to associate the toast notification with.
The issue is my application is installed on various peoples computers already and each computer already has a shortcut in the start menu for the application. As of now the GUID that was generated in the designer of my form is not linked to anything and the toast notification popup only show this GUID instead of the application name and icon.
Is there a way to retrieve the application ID used in the existing shortcut file by the installer and set that value in my ToastNotificationsManager? This way my updater can replace the .exe on everyone's computer and the messages instantly begin showing properly.
Since IBM Process Designer is eclipse based, ¿Is there a way to change the user interface language to other than english (i.e. Spanish)?
I've found the way to change the GUI Language for Process Center, taking the following steps:
Open Process Center's URL (something like https://[server ip]:9444/ProcessCenter/login.jsp) and then login with your user/password
Open "Preferences"and then in "User Preferences" dialog select the new language you want to set.
Logout from Process Center
Opened Process Designer and the interface shows the newly selected language (the same happens with Process Center web page)
Hope this helps someone else.
I need to create a simple Delphi application, kiosk style.
It is a very simple thing, a single form where the user writes some personal info to register to an event. 4 TEdit and a TButton.
What I want to achieve is to avoid the user does any action different then typing in TEdit or clicking on the TButton. For example I don't want he does ALT TAB (switchin applications), pressing windows key on keyboard, doing ctrl-alt-canc, etc...
I can add a passowrd protected Button that enables/disables this "Kiosk mode", in this way as I need to exit the kiosk mode I simply press that button and exit.
How to achieve this "kiosk mode" in Delphi without intercepting all the keystrokes manually? Or did anyone already develop this so it can be shared?
I think you'd better create a new desktop, and run your app in there. When your app is done, you can bring back user's desktop. That is how Windows login screen works. Of course Windows login screen uses a special secure desktop. Your app in a separate desktop would be isolated. You will have a desktop background with no start menu, taskbar, or desktop icons because explorer.exe is not running there automatically. Of course a can start a new process, using Task Manager, but desktops in Windows are securable objects; therefore, you can make restrictions if you want. Of course if your app has sufficient permissions.
To create a new desktop, you can use CreateDesktop Windows API, and to switch to the newly created desktop, you can use OpenDesktop function.
You can try Change the Windows Shell.
When you start windows, you don't execute the default shell (explorer.exe), you can execute your application.
Al internet you can find alternative Shell (more attractive) to default windows like:
BlueBox or
SharpE
This option is used for purposes similars at the application that you are developing. Kiosks or TPV.
For change the default applicacion you must modify a registry key:
In Win3.x and Win9x, SYSTEM.INI file:
[boot]
shell=MiAplicacion.exe
In Win2k and WinXP, use Registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
Shell=MiAplicacion.exe
If you test this option, think the mode to turn the configuration to the original value (button or option). You must reboot to test changes.
ADDED: In addition, if you search on the web some similar at this "Delphi Change default windows shell", you can find more code, samples and information about this.

P.D: Excuse me for mistakes with english.
Well but if someone can open the taskmgr he could just create a new task and run explorer.exe from there so its not really secure though...
Ok Taskmgr can be stopped with policies...
Well and for disabling the cad sequence you can use saslibex which Remko Weijnen had created you can find it here: SASLibEx
kindest regrads,

I want to be able to send a stream of data from a user computer to a web-service. That should not be too hard - I would use an application written in dot-net that resides on a user's Windows computer.
However, the tricky part is that the stream-of-data should only be sent (by the app) when the user clicks on a button or a link in a WEB PAGE that is open in his browser. The app itself would be minimized in the system tray. And he should be able to stop the stream by clicking on a stop-button (or link) in that web page..
So I found some info on stackoverflow that says that you can put a link in your page, something like: [a href='alert:"Hello World" ' ] and if you register your application (in this example the app would be called "alert.exe") in the registry, then when the user clicks on the link, he will cause the application to start, and to receive "Hello World" as a parameter.
Anyway, there are complications in my case. I want to be able to tell the application when to start sending data, and when to stop sending data, without starting new instances of the application. If the user clicks START, and the app is already open, I don't want it to open again. I do want a message to go saying "start sending" and if the user clicks on a STOP button (or link) to say "stop sending". The user might click on these web-page buttons several times in a session, and I don't want to close and reopen the program each time.
So a couple of questions:
Am I taking the right approach? Would "plug-ins" be a better idea?
If I am taking the correct approach, is there some way to send commands from a web page to an application?
Is it safe to have my app modify the registry of user computers?
If so, is there a set of commands for doing that?
Is the registry supported by Windows 7, Windows 8, etc? I know it is not supported on a Mac.
Thanks in advance.

P.S. (the info on launching apps from your browser was at: http://msdn.microsoft.com/en-us/library/ie/aa767914%28v=vs.85%29.aspx).
Requirements:
Our application replaces the usual windows shell (explorer.exe). This is a product requirement for a closed system that we're supplying.
We oughtta let the user select a wi-fi network and connect to it.
The problem: The wi-fi networks dialog only shows up when explorer.exe is running
What we tried:
Write our own wi-fi manager that uses wlan API. It lists connectible networks and allows the user to connect/disconnect. Problem: too many network types/configuratons that have to be tested, especially when the wheel has already been invented and reinvented all over.
Try and check how is the networks dialog implemented. It appears that it's and undocumented COM interface (IUIRAdioManager). Problem: it's undocumented, so no API
Use an existing network manager, for instance the one that comes with the driver. Problems: it's ugly, not to the product's taste; and it opens too many options for the user, like creating and loading profiles, browsing for files on a file system - these things are unacceptable.
Running explorer.exe just for the purpose of showing the networks dialog and then killing it. Problem: once we run explorer.exe - it pops up metro view and hides our fullscreen application or shows the taskbar.
The latter seems like the preferred solution: no need to reinvent the wheel, it does what's needed. Just gotta make explorer.exe not pop out, keep it quiet in the background.
So, we're down to two options:
How to show the networks flyout dialog without explorer.exe?
How to run explorer.exe without it popping out metro or taskbar above our application?
Your first solution would be incredibly difficult to implement. I am almost certain that the Networks window is dependent on explorer.
However, your second is entirely possible.
To hide the taskbar, you will need to find a window (using FindWindowEx) to find the taskbar (name is Shell_traywnd). This will hide the taskbar and start button. EDIT: Unless you are implementing your own taskbar, you might want to set the taskbar to autohide.
Next you will need to hide all of the metro programs. In a similar fashion as above, find the class named EdgeUiInputWndClass and close it. You should be able to get the process name of it and then kill the process.
Windows key. This is a little more difficult. You will probably need to use a program and delete the key or a keyboard hook (a low level keyboard hook) and just ignore key presses with the same scancode as the windows key. Left Windows is 0x5b and Right is 0x5c (source). Note that this will not block Ctrl+Alt+Del.
Finally, to show the Flyout, you can run %windir%\explorer.exe shell:::{38A98528-6CBF-4CA9-8DC0-B1E1D10F7B1B}
(source).
EDIT2:
You should also be able to hide toast notifications via this
Of course, I don't see why you cannot just use Windows 8/8.1 and put the app in kiosk mode.
