Java Forum / General / May 2006To minimize the java window tosystem tray
I am programming a application which is based on socket . And i want that it starts at system startup and a method which can minimize the java frame to system tray so that the client can't notice it . Or i want that it even can't be at system tray ,it should be hidden process like the processes which we see in task manager's processes tab.And one more thing how i can make the process in a waythat it cant be stopped ,like explorer.exe,and if someone end it the system also gets shutdown. >I am programming a application which is based on socket . > > And i want that it starts at system startup and a method which can > minimize the java frame to system tray so that the client can't notice > it . Java 1.6, which is coming out soon, is supposed to have support for the system tray. > Or i want that it even can't be at system tray ,it should be hidden > process like the processes which we see in task manager's processes > tab. Isn't this just like writing a regular Swing application, except you never actually call setVisible(true)? >And one more thing how i can make the process in a waythat it cant > be stopped ,like explorer.exe,and if someone end it the system also > gets shutdown. Not sure that it can be done in a platform independent way. Sounds like you're mostly interested in Windows though. Maybe use JNI in combination with http://www.codeguru.com/cpp/w-p/win32/tutorials/article.php/c8647/ - Oliver > I am programming a application which is based on socket . > [quoted text clipped - 5 lines] > process like the processes which we see in task manager's processes > tab. It sounds like you want to write a daemon. For Linux-like platforms, you just need to write a script or two to start and stop your program, and put the script in the appropriate rc file directory. For Windows, you'll need to register your program as a Windows Service. JET claims to help with this: http://www.excelsior-usa.com/kb/000019.html > And one more thing how i can make the process in a waythat it cant > be stopped ,like explorer.exe,and if someone end it the system also > gets shutdown. That's not how explorer works. A redundant process (or possibly part of the kernel) polls the Windows shell (explorer.exe) periodically, and if the process doesn't respond, it gets restarted. This doesn't seem to work particularly well on my own XP boxes. Intentionally bringing down the whole system when your program crashes sounds like a spectacularly bad idea. Like Darwin Award bad. Would you please post a quick description of why you want this? My curiosity is piqued. >> I am programming a application which is based on socket . >> [quoted text clipped - 25 lines] > please post a quick description of why you want this?

It's hard to think of a GOOD reason for doing what he wants to do. -- Rhino >>> I am programming a application which is based on socket . >>> [quoted text clipped - 29 lines] > virus for example.

Part of me thinks it would be appropriate to inform the India authorities.

You put in quarters and you get to play games that you could otherwise play for free on the internet (e.g. tetris, bejeweled, etc.) Anyway, I was just messing around with the device, pressing my finger all over the touchscreen as quickly as possible when the machine crashed. After a few seconds pause, the machine rebooted itself (it was running some variant of Linux, for the curious), and got back into the lobby, where I was prompted to select a game, and insert money for the priviledge of playing the selected game. I guess this is more desirable than having me go over to the person who gives you change and complain about how the machine swallowed my quarter, and having the person stare dumbfoundedly at the frozen machine, with no idea how to fix it. - Oliver > Or i want that it even can't be at system tray ,it should be hidden > process like the processes which we see in task manager's processes > tab.And one more thing how i can make the process in a waythat it cant > be stopped ,like explorer.exe,and if someone end it the system also > gets shutdown. If you don't know enough about Windows system programming to be able to do this without help, then you /definitely/ don't know enough to be trusted to create such a dangerous program. BTW, why ask a bunch of Java programmers about Windows system programming ? I suppose there may be a few Win32 experts here, but it's not the place you'd expect to find many. -- chris Free MagazinesGet these publications absolutely FREE for up to 12 months.
