Auto reload of Panel

Hello,
I am working on maintaining an application on swing. Every time I do a change in my Panel Class which extends JPanel, I need to stop my application and then again start it. A lot of time gets wasted in stopping and starting again as it gets called from other panel's(application workflow) etc.
Is it possible to get the Panel autoloaded after recompilation, as it happens with Servlets and jsp's.
Thanks and regards

It's not possible

Safari 5.1 strange auto-reloading behavior for tabs in the background

hi guys.
I have been encountering this strange behavior recently. I had thought it could be something wrong with my system, until yesterday i upgraded my Safari for Windows to the v.5.1 on a Windows XP laptop, and found the same issue. Now i guess I can be quite certain this is a safari issue.
System info:
1. Macbook Pro 17", OSX 10.6.8, 64bit boot (i have 8GB RAM).
2. Safari (Mac) is the lastest version (as updated by the Auto update), run in the default 64bit mode.
3. The windows machine is an old Thinkpad T60 with Windows XP Pro SP3. The Safari for windows is Safari 5.1 (7534.50), also updated by auto update.
4. I have not installed any Safari extensions/plugs that feature an auto-reloading -- as such behavior was never seen before i upgrade to Safari 5.1
Since i mostly work on mac the mac has been kept most updated. But the windows machine which i use now and then, i don't update everything very frequently. And the earlier Safari 5.0 worked fine without the current issue.
Symptoms
1. Let's say I have 1 Safari window open with 5 tabs, and I have been working on the 4th tab for a while, and left the other 4 tabs "idling" in the background.
2. And then i want to switch to another tab: click on that tab, and that tab will come to the foreground while being automatically refreshed.
3. It looks to me this behavior happens after the inactive tabs have been idling longer than a certain period of time - then if you switch to them, they will be switched to and in the same time auto-reloaded. But I still don't know how long it needs for the "idling" before an auto-reloading "threshold" is triggered.
4. In the beginning this was just on the Mac Safari (and i hadn't updated safari on the windows). But after I updated safari for WIN yesterday, i found the same behavior today.
5. I checked all the Preferences settings and didnt find any option that indicates this behaviors.
Guys. any ideas? anyone have the same trouble? Thanks a lot guys. This is really annoying.

I'm running Safari 5.1 / SL v10.6.8 on one Mac with Glims installed and I never have a problem with tabs auto reloading. You might want to give it a try.
It's free!

Once the software is installed you can access the settings from Safari / Preferences - Glims.
If you don't like the software you can use their uninstaller here.
Hi Carolyn thanks a lot for the idea.
The weird thing is... after i tried to uninstall and re-install a few apps the "auto-loading" behavior disappeared ... guess something was interfereing with safari 5.1...
But thanks for recommending Glims. I took a quick look at the website and it looks great. will do some more research before i start using it. Thanks for the recomm!

Im running a web-based CMS, that cycles through a number of pages, and wanted to know if there is an auto reload code option ( not plug-in ) that can restart previous page when connection failed.

I am running a web-based CMS that cycles through a number of pages, each for different times ( ranging from 40 seconds to 2 minutes )and is displayed in a number of shops. Every now and then our internet drops, and the page errors with connection failed. I’m wondering if there is anyway to auto reload the page as soon as the error connection failed is showing. auto-reload addon is not an option as this will interrupt the sequence.
The following error was encountered: 
 
<ul><li>Connection Failed</li></ul>

I want to allow redirects but not auto-reloading

I'm running Yosemite on a Mac Air, with fully-updated everything.
I'd like to stop pages reloading without my permission. This is usually an issue for me on news sites.
In FF preferences, the option to allow or disallow auto-reloading is tied to the option to redirect. I can allow or disallow both, but not allow one and not the other.
The net effect is, my news sites aren't automatically refreshing (yay), but other sites get stuck when a page redirect comes up. I play Scrabble online; now I have to manually allow a redirect with every play. Same with following Twitter links.
Is there some way to kill off the auto-reloads while still allowing redirects? Maybe a whitelist for redirects, as a secondary option?
Thanks!

I do not know if the browser can tell the difference because it depends on the DNS server to give redirect requests back to the browser. Actually it does, 301 or 302 vs new http get request.... anyway:
I found this add on: [https://addons.mozilla.org/en-us/firefox/addon/refreshblocker/ Refresh Blocker] and [https://addons.mozilla.org/en-US/firefox/addon/noredirect/?src=search No Redirect] which both let you control what sites to allow if there are only a few sites.
This would only be a temporary work around however.

Premiere doesn't auto reload footage.

Premiere Pro CC on OSX...
I am rendering out various 3d files from cinema 4D as a PNG image sequences and I am making small changes and re-rendering them. Premiere however does not auto reload them. I have to do the replace footage to clear the cache and bring them in.
I know After effects does this properly now, but is this a premiere bug/quirk/lack of functionality? Or Is this just me?

When I right-click on a file from the bin and select "Reveal in Finder," the correct file is shown. When double-click on a file, the source monitor shows the correct clip. The same goes for when a file is selected from the timeline. However, since the in and out points have been moved to a point after the clip is over, there is no video to display. So what I am wondering is: how did the in and out points get shifted, and if there is a way to fix it all at once, rather than manually changing each clip.

Reload different panels

Hello all,
Like to reload different panels onto the same load panel.
Code sample below on what I'am trying to achieve
Each panel size would like to be 45% of window size.
Have problems of reloading different panels to achieve the size and
also when resizing the window
Have 8 dukes to get rid of from:

Safari auto reload

Every time I move between tabs on safari on my ipad, the page auto reloads. How do I disable this feature. Extremely frustrating because of reload when out of wifi zone, I waste time reloading on slow 3G networks and it also increases my bandwidth consumption. Kindly help with very annoying feature

It's even worse than that. When it reloads, if you were typing data in a form, such as the reply that I'm writing Right Now, Safari wipes out all your input and you get to start from scratch. That means you can't switch between browser tabs to research whatever it is you are typing.
It wouldn't even be that hard. Most such things are fairly simple HTML "forms", all it would need to do is store the content of those "form" fields when you tab away. So if it had to reload, it could repopulate your entered data from that. Forms are very simple, just any number of pairs of {fieldname, fieldcontent}. For instance the fieldname might be "Text" and the fieldcontent might be what you are reading right now. Preserving the state of this form I am entering here would take less than 1 kilobyte (0.001 megabytes).

Is it possible to disable auto reloading, permanently, for one specific URL?

msnbc.com is supposed to auto-reload its home page every however often, 30 minutes I think. But the reload never stops, probably because of my AdBlock settings for the site. I want to permanently stop msnbc.com from reloading. I've searched thoroughly with many keywords, and though I've found many extensions that will reload pages or set auto-reload intervals, I can't find anything that *stops* auto-reload. I'd appreciate any help.

Mike,
Not sure if I completely understand your dilema. I don't know of any way to pause a FMR, however, I may be able to help with plan B. I have a widget called Repo Playbar that allows you to reposition the playbar AND show/hide any playbar buttons, including the play/pause button. Have a look here.
HTH,

How to stop irritating auto-reloading of the tabs (pages) [i don't have any extensions or apps]

Seems like this problem appeared quite often, nevertheless i spent an hour in search of an answer surfing the net, alas, nothing..
Problem: since today Safari started to reload almost every single page whenever i switch between tabs or sometimes even while im stil on the page. Fot example - i'm watching a movie, stoped it - switched to facebook tab to reply to my friend, then back to the tab with the video & no sooner i get back as the page with video auto-refreshes itself & i have to load movie again & look for the place i stoped watching the video to continue!
Device & program version: Macbook Pro, bought in july, Safari Version 5.1 (6534.50), No extensions or apps installed, & pls dont' say that it happens on particular pages, i visited the same ones yesterday & everything was ok, since today it's working all weird, and happens within all pages. But in the same time no system - once it reloads the page, other time im switching between the same very tabs it doesn't.
This is unacceptable & completely useless. Why there are no comments from Apple or Safari team, as if the problem doesnt exist? Not speaking of the problem solving process or tips.
Please, if someone knows how to stop this nightmare - tell me!!
Apple-team, I would love to hear your comments & in fact receive some help and get this problem fixed.. :\

If your Mac is runing Lion v10.7 try disabling Resume.
How To Disable Lion's 'Resume' Feature - MacRumors.com

Why can't we disable auto-reloading without having the nag bar every time it does its job?

Blocking page reloading (or auto-refresh) and being "warned" about a blocked page reload, should be two, separate items in Prefs, or config. Period. If someone wants to be "alerted" or "warned" every time their settings are acted-upon, so be it, they can choose to be warned. As it stands, the only way to block the annoying auto-refresh, is to choose the annoying nag.
Where is the logic in that? What next? Maybe we should have an alert every time a new tab or window opens, that says, "Firefox just loaded a page you requested."
Why not follow the structure, already established, over and over, in Firefox's preferences, whereby a user can make one choice, and then there are sub-items that can also be chosen, or not chosen? (i.e., 1-Accept cookies from sites (check, or no check), a) Accept third-party cookies (select from Always, From-visted, or Never)?

Auto Reload/Refresh of page or content

I am a newb to Edge Animate and coding in general. I am developing a mobile web page with text on it. I need to update the text and have users see the updated text without having to reload/refresh the page themselves. Is there a way to have the page auto-refresh or another way to ensure people see the updated text if they already have the page loaded on their device?

Hi Friend,
Use Javascript utility for auto-refresh the page.
Following example will be helpful to you:
<html>
<head>
<script type="text/JavaScript">

</script>
</head>
<body onload="JavaScript:timedRefresh(5000);">
This page will refresh every 5 seconds. This is because we're using the 'onload' event to call our function. We are passing in the value '5000', which equals 5 seconds.
But hey, try not to annoy your users too much with unnecessary page refreshes every few seconds!
</body>
</html>

Can I make cluster servers auto reload html files without redeploy applications?

For example, I have some html files under application directory, these html
          files were
          generated and synchronized to all clustered servers by other external
          programsfrom time to time¡£ But with weblogic, I have to redeploy these html
          files to enable these files been viewed via browser.
          Is there any way to let weblogic auto refresh these files without redeploy?


OS X Lion- About Auto Save and Versions
Handles this automatically. Otherwise, such frequent backups will overtax the drive and probably cause some slowdowns, but you can change the interval using the freeware utility, TimeMachineEditor 3.0.3.

How to Save & reload front panel position

I would like to save the front panel position into an ini file or registry, so that the next time the program is used, it comes up where the user left it.
With the Invode Method: Front Panel.Run-Time postition.Get positon
I can get all the position data I want:
left-top
state
monitor
However... How do I set the same information at startup?
There's no Front Panel.Run-Time Position.Set position. as far as I can see...
To set position, state and monitor values, it seems I need to first call FP.Open for the state, then FP.Run-Time Position.Centered to select the monitor, and then FP.Run-Time Position.Custom to set the position....
That looks weird and complicated...    Am I missing something here?   Is there a more elegant approach?

NI explains the difference between Property nodes and Invoke nodes as this.
Property nodes access the properties of an object and allow you to read/write those properties.
Invoke nodes perform actions on an application or VI allowing you to get and sometimes set attributes of those actions.
Sometimes there is some overlap between Properties and Methods as you noticed with the "Get Position" method and the "Panel.Position" property. But most of the Methods do not have a similar Property. For instance, there is a Method you can use on a front panel item called "Get Image". This will return image data about the item that will let you save the items current visual appearance to a graphics file. (.bmp, .png, .jpg) There is no equivalent property to do this.
So it really depends on what you are trying to do as to which one you end up using.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

Auto reload ALV list display.

Hi,
Anyone has any idea, i am require to auto re-load my ALV list with new data after regular interval.
I am using REUSE_ALV_LIST_DISPLAY FM
Thanks,
Ad.

Vijay is right. Here is a sample program, I'm using a custom database table to show in the ALV list. I couldn't seem to get this working using the "REFRESH" fucntionality that I believe to be built in, so I am using the "EXIT" instead. Its working.
Also, this sample uses a local implementation of the class CL_GUI_TIMER. REason for this is, I'm on a 46c system and that class does not exist.   I copied the class out of another box and make it a local class.

LV8.0 Auto-print front panel doesn't work

On the front panel in VI Properties/Print Options the 'Automatically print front panel every time VI completes execution' is cleared when you exit the VI Properties dialog and return to it. Consequently, you can't get the front panel to print by checking this option.
Brent

Bshu,
You're absolutely right. That functionality is faulty. A work around may be to use the operate>>print at completion function. FYI: if you enable this property, the VI Properties/Print Options the 'Automatically print front panel every time VI completes execution' turns black. R&D is aware of both of these problems. Thank you for you're very valuable feedback and post to let us know if there's anything else we can help out with.
