I have worked in project for long time but after electricity has cut off and my PC shutdown.
The code in one of my frames not shown correctly, it's showing like this :
I have GUI and its shape is fine. When I run the frame from main interface it works, but as I said the code is corrupted. I don't know why. If any one has any solution for this problem it would be much appreciated.
In your Netbeans IDE,
Open Projects window (Ctrl+1) ,select file-> right click on list select Local History-> Select Local History. It will show all your last edits. you can restore the last updates from there.
In Latest netbeans releases you can directly access this from toolbar, check the below screenshot.I took this from Netbeans 7.3

For some reason, Netbeans IDE 8.2 won't apply any different themes than the original one. Has anyone else had an issue with this? I have applied the new theme and restarted the application many times without success. Thank you.
It's very hard to identify what is wrong since everything in your screenshot looks perfect, and Sublime-Theme works for me using NetBeans 8.2 on Windows 10. See the file with the tab NewServlet.java in the screen shot below.
Note that using Sublime-Theme does not impact everything. For example, the Projects and Navigator panels don't change. Since your screen shot only showed the Options window, and the Start Page doesn't change in the editor either, are you absolutely certain that none of your files in the editor are using Sublime-Theme?
Also, you say that "Netbeans IDE 8.2 won't apply any different themes than the original one", but NetBeans comes bundled with several themes, such as NetBeans and NetBeans 5.5 as shown in the screen shot below. How many options are shown in the profile drop list for you? If you select a different theme from the Profile list and click Apply the rendering of your files in the editor should change immediately. Is that happening?
If so, the problem is probably confined to the installation of Sublime-Theme. Try deleting Sublime-Theme (the button is in the top right corner of your screen shot), and then import the zip file again to see if that fixes the problem. Also, verify that the Sublime-Theme zip file you downloaded can be manually unzipped since it might be a corrupt file.
Another thing to try is using some alternative plugins. Select Tools -> Plugins -> Available Plugins and then install Dark Look and Feel Themes and Darcula LAF for NetBeans. If those don't work either then there is something fundamentally wrong with the installation of NetBeans.
Finally, this article titled The complete guide to tuning the appearance of NetBeans may be helpful.
I use Eclipse Neon under Windows 10.
I installed a plugin (MonjaDB) using Eclipse Market Place. As I didn't find the plugin to be very useful I uninstalled it using Help->About->Installation Details->Installed Software->Uninstall. Sadly, however, this didn't seem to fully remove the plugin.
I now have a small red square on the right hand side of my workspace in the shortcut toolbar. This cannot be removed using the close option. I went so far as to remove my installation of Eclipse and the .eclipse directory in my home area but after a reinstall the square is still there.
Presumably this means that it is somehow associated with the project in my workspace?? Does anyone have any ideas how to remove this annoying square?
EDIT:
I have noticed two things
The MonjaDB perspective is hanging around somehow and
If I press the little red square on the right it opens an empty tab in the tab set to the right (where mylyn sits) with the title of DB Tree but I cannot remove it.
I have added three screen shots
MonjaDb perspective Partly Active
It seems like your current perspective is the one that was uninstalled. Just try opening a new one via the Open Perspective toolbar button that's close to thevred square, and then you can try right-click > Close on the red square.
At least a part of this is intentional...when the implementation class of a view no longer exists we leave the view 'open' but are supposed to show an "Error Part'. The reason to leave it up is to handle cases where a user has installed a new eclipse and opens his old workspace before installing the extensions. If we were to remove the views the user would have to set up their perspectives again once they had installed the extension.
Note that resetting the perspective won't work because the class implementing IPespectiveFactory no longer exists.
Closing the perspective and opening a new, different, one should work. If the perspective you open has visible views that are no longer available you should just close them.
I have a little problem and I hope someone can help me.
I'm using Eclipse, and i'm trying to add a Java Working Set folder to my Workspace.
The problem is that when I try to do it (right click, new, Java Working Set, and set the name) the first time works fine, but I can't see any change in the workspace (no folder appear), I have tryed to refresh the workspace but it doesn't work (and close and open Eclipse).
When I try to create it again, it says: "a working set with that name already exists", but I can't see it.
Can you help me please?
Working Sets are not folders, they are just a collection of objects.
You may be thinking about how Package Explorer displays projects. You can tell Package Explorer to show Working Sets by selecting 'Top Level Elements > Working Sets' in the view menu (click the small down pointing triangle at the top right of the view).
Something quite strange has happened: The whole Eclipse main window disappeared while I was debugging a Play Framework project. The Eclipse symbol in the applications bar still shows up as usual (from where I still can force Eclipse to quit).
My System (Ubuntu 14.04.) still behaves as if Eclipse was there, e. g. other applications get unfocused when choosing Eclipse in the applications bar. Meanwhile I have re-started Eclipse (that didn't help) and even re-started Ubuntu (still the same behaviour).
When I start Eclipse the workspace selection window shows regularly up. If I select another workspace, it also shows up regularly (I have created a second one to test that). Eclipse even still reacts properly on any shortcut as well as well as F10 & F11. It seems like the Eclipse main application window was "transparent". Therefore I assume that it is a problem of Eclipse resp. its workspace rather than an Ubuntu problem.
Does anybody have an idea where to maybe re-configure the workspace? Or is there even a secret function for all that?
Thanks a lot!!
Meanwhile I was able to re-get the window: I clicked on a shadow effect that sometimes showed up. I resized that shadow with my mouse. As an effect the Eclipse window top bar (the one above the menu) showed up again. Afterwards I could "pull out" the window from the bar - and there it all was again... But I have still no idea, how that happened - and what might be the solution if someone runs into that issue without having a shadow.
I often end up with lots of empty panes in Eclipse that can only be minimized but not destroyed. How do I close these?
Update:
In this screenshot you can see two minimized on the upper left and several on the right hand side. In the center are four more. They only seem to be restorable in the Debug mode.

this happened to me, too. What worked for me (based on FilmJ and douncon's comments) was to open a class file, then drag that tab over the top of the empty pane.
Select Window -> Reset Perspective. That should reset the current perspective (what you call "mode") to its' initial state, (hopefully) closing all irrelevant views.
Something seems terribly wrong with your Eclipse. Maybe you should reinstall it. It is possible that you installed a buggy plugin.
First of all, what do you mean by pane? Eclipse has:
Windows (Eclipse itself, e.g. instance)
Documents (tabs)
Views (properties, tasks, explorer, etc)
If by 'pane' you mean document editors, you have problems either with your Eclipse version or most likely one of the installed plugins.
Each View also can be closed (except maybe some project types (perspectives) of which I'm not aware). For CDT (C/C++) you can close practically everything.
I'll recommend you download latest Eclipse version with no plugins, extract it to different folder, and check if that happens again. If yes, please explain more in details (like Eclipse version, perspective you are using, any side plugins, etc).
Also a good places are Eclipse community forum, mailing list and bugz :-)
I had the same problem. For me it helped to go into the right perspective and activate the functionality that caused the window in the first place. Once I reactivated the functionality, in my case "QNX Memory Analysis perspective", I was able to close all the windows one by one.
The conclusion is you have to refill the empty windows with content and then you will be able to close them properly.
So, it's really very easy for this to happen, if you open an editor that's incompatible with the existing editor, you can often end up having to place it outside of the tab list in one of your editor panes, then you might clear or copy that, typically while trying to add that view to a tab list.
In any case, what it's done is create a new editor, and all you need to do is drag some file to that empty editor window giving it some form of context, then close it.
I had the same issue. I followed #zvikico, but instead of just resetting, I first reset and then closed all the perspectives. Please follow the following to fix the problem. It worked for me:
Window -> Perspective -> Reset perspective..
After resetting follow below:
Window -> Perspective -> Close All Perspectives
