• how to block select, move, copy, paste in vi?

  - by gojira

  I am trying to migrate from Notepad++ to vi. In N++, I constantly rely on block edit (or "column mode"), as it is a great increase in productivity: I can select a rectangular area of text by pressing ALT before marking with the mouse, and copy, move, paste the rectangular area anywhere. Also, it is possible to drag the cursor vertically so that I can type simulatenously on several subsequent lines at the same time. Is there any similar functionality for vi? If yes, how can I do that?

• Jquery CPU usage

  - by nharry

  I am using Jquery to make an image scroll across my page horizontally. The only problem is that it uses a serious amount of cpu usage. Up to 100% on a single core laptop in firefox. What could cause this??? Jquery <script> jQuery(document).ready(function() { $(".speech").animate({backgroundPosition: "-6000px 0px"}, 400000, null); }); </script> CSS .speech { /*position:fixed;*/ top:0; left:0px; height:400px; width:100%; z-index:-1; background:url(/images/speech.png) -300px -500px repeat-x; margin-right: auto; margin-left: auto; position: fixed; } HTML <div class="speech"></div>

• Ubuntu terminal questions

  - by Camran

  I am wondering about my VPS providers ubuntu terminal. Are all these terminals the same? I think they are so user-UN-friendly. I can't copy-paste into the terminal, when I try opening textfiles, I can't scroll up and down easily. I cant save easily. Nothing is easy... Is it always like this with Ubuntu? Is there any way to make it easier? I use windows but I login to my vps provider with login details and then simply click "terminal" to open the terminal. Please help me out here

• Forbid GridView to load all views at once

  - by efpies

  I have about 700 items to display in the grid view. On a Samsung Galaxy Tab 10.1 this is not a problem: it has enough memory. On a HTC Explorer the heap is overflown. So I want to load data dynamically regarding current scroll position (N rows for screen + 5 rows as a tail). And I want to show a scrollbar which represents the position in total rows. But I don't want to draw items that I don't see. In other words, I want to create something similar to UITableView in iOS. How can I do this?

• Server 2008 unresponsive after SP2 install.

  - by Dan

  I have a dev server that has an exact image of a production web server. The prod server only has SP1 installed on it. When I first fired up the dev box, the first thing I did was install SP2, and let it be. Almost every morning when I came in, the server was unusable. It would respond to ping, but RDP and the web site running on it were down. On the screen the screen saver was bouncing around, so it wasn't hard locked. But it was unresponsive to keyboard and mouse. So now I have to hard shut it down, but when it comes back up, the only thing in the event viewer is the unexpected shutdown, nothing else. I've since taken a fresh image of my prod box and put it on the dev server, and not installed SP2, and the dev box is humming along perfectly. I should also note that this is Server2k8 Web, 64bit Has anyone else seen anything like this?

• Persisting a single UISearchBar instance across 4 separate UITableViews

  - by Jacob Relkin

  Hi fellas, I'm in the midst of an iPhone app that needs to have 4 separate UITableView objects sharing access to one UISearchBar in the first section and first row of the aforementioned UITableView objects. I have tried to offset the UITableView's frame by 44 pixels, then adding the search bar as a subview of my UIViewController's view. That works, but I cannot use the table index to scroll up to the search bar, since it is not a cell in the tableview. I need to have the search bar in the table view itself. My goal is to have the same UISearchBar in the first section of multiple tableviews. Thanks so much.

• Kindle for PC - page loading problems

  - by Andrew Heath

  When viewing books in Kindle for PC, often going to the next page will change the line count at the bottom of the screen but not refresh the page view. Then, if you hit next again, you end up on the next next page (+2 rather than +1). This happens to me going backwards as well. Using arrow keys, or mouse clicks, or page down/up all creates this error. There doesn't seem to be any pattern to the occurrence other than "frequently". It happens on my Win7 64 bit and Win XP machines. I've only one Kindle book at the moment, PHP Object-Oriented Solutions by David Powers, so I suppose it could be a problem specific to that book. Does anyone else have this issue? It is extremely irritating to be constantly flipping back and forth just to get the page view to show the proper page.

• IconDownloader, problem with lazy downloading

  - by Junior B.

  My problem is simple to be described but it seems to be hard to solve. The problem is loading icons, with a custom class like IconDownloader.m provided by an official example from Apple, avoiding crashes if I release the view. I've added the IconDownloader class to my app, but it's clear that this approach is good only if the tableview is the root. The big problem is when the view is not the root one. F.e: if I start to scroll my second view (the app now load the icons) and, without leaving it the time to finish the download, I go back to root, the app crash because the view that have to be updated with new icons doesn't exist anymore. One possible solution could be implement an OperationQueue in the view, but with this approach I've to stop the queue when I change the view and restart it when I come back and the idea to have N queues don't make me enthusiastic. Anyone found a good solution for this problem?

• iphone indexed table view problem

  - by steveY

  I have a table view in which I'm using sectionIndexTitlesForTableView to display an index. However, when I scroll the table, the index scrolls with it. This also results in very slow refreshing of the table. Is there something obvious I could be doing wrong? I want the index to remain in place on the right while the table scrolls. This is the code I'm using for the index titles: - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { NSMutableArray *tempArray = [[NSMutableArray alloc] init]; [tempArray addObject:@"A"]; [tempArray addObject:@"B"]; [tempArray addObject:@"C"]; [tempArray addObject:@"D"]; ... return tempArray; }

• Is there keyboard shortcut to move input focus to the Google Search box?

  - by Chen Jun

  I'm searching on Google a lot. I find it very annoying to move my mouse to the search box and click once so that I can input another search term. I did Googled some time, but no one seems to be annoyed with this, quite unbelievable. I'm using Firefox 8 and Chrome 16, on Windows 7. If you know Atlassian Confluence, you might probably know that pressing / will move input focus to the upper right search box, very convenient for a keyboard shortcut hobbyist . Try it here.

• Loading a datagrid with large amounts of data in silverlight?

  - by JD

  Hi I am breaking up my project in small sections and one of the sections involves loading a grid with possibily lots of records (could be up to 1000s of records in the database). Ideally I would like some sort of mechanism where as the users scrolls the grid, more data is retrieved. I have read that certain controls (datapager with RIA) do this but I would like to know how I could implement this myself or do something similiar? I was thinking about first loading 50 records at a time and when the user gets to scroll near the 50th record, then get another 50 as a start and so on. Not sure how I do this but this does not feel right or whether I should load ids of records in the grid and then get each row to load itself via an async thread but then I am hitting my database for each record? Thanks JD.

• VIM is great for text. Is there, too, an efficient, mouseless way to manipulate files on OS X?

  - by Dokkat

  I am having trouble navigating through files on OS X. That is, creating files, copying, moving, and so on. I am currently using the Finder, but the act of clicking with the mouse is not very efficient. Acessing a deep folder takes a considerable amount of time and you'll have to know it's entire path. When I try to use the command line it is even worse. Going to a folder requires at least typing it's entire path with the 'cd' command; and, when you are there, you don't have full control over it. For example, how would you move 3 specific files to another folder? Some text editors offer a 'fuzzy search' function that allows a very fast form of jumping through files. What is a fast, efficient way to navigate through files on OS X?

• Re-measuring custom item renderer on a List

  - by leolobato

  I'm writing an Adobe Air client to a service similar to Twitter. On the timeline (List component) I have a custom item renderer which is basically a Canvas with a fixed-width Image and a Text control, which is multi-line. If the text is long enough to change the Canvas height, it will only be resized if I manually change the width of the Window, forcing a redraw of all renderers. If I simply scroll through the List, all "new" renderers will have the minimum height possible (which is the Image height). Any ideas on how to force the re-measurement of the renderer when I set it's data? Thanks in advance! :)

• What CSS should I use to create a series of horizontal, non-wrapping blocks?

  - by JOhnC

  I have a set of dynamically generated content - anywhere between 1 and about 25 blocks (each of which I want to be about 250px wide. Clearly, this can run off-screen, but that's fine since my design allows for horizontal scrolling (using jQuery - I don't want the browser to do it with its own scroll bars). So what CSS - cross-browser - is the best approach? Floats seem to wrap unreliably, and the dynamic nature of the content which changes frequently through ajax calls - means that recalculating the container width is not very practical. Other CSS-based option?

• ctrl-c, ctrl-v not working on Windows 7

  - by Beth

  I'm trying to use my Windows 7 PC, and for some reason, Ctrl-C to copy and Ctrl-V to paste only work intermittently. I have a third-party clipboard viewer installed, so I can see when Ctrl-C doesn't copy to the clipboard (there's no new entry) and also when Ctrl-V pastes glarp (the cursor moves, sometimes several lines) instead of what's on the clipboard. I've checked the keyboard and mouse drivers, run a system scan, checked the event log and a bunch of other things I've seen online, and haven't found a resolution. Any other ideas for things to check or try?

• How to make an scrollable UITextField Inside UItableViewCell?

  - by user333624

  Hello everyone. I created a bunch of editable UITableViewCell by embedding an UITextField inside, but I have seen some apps that allows you to scroll the UItableview by scrolling inside an inactive editable cell. How can I do that? And how can I also dismiss the keyboard when tapping somewhere else? I know about the method: - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; if (touch.tapCount == 1) { [self resignFirstResponder]; } else { }} I put it inside my custom table view controller but the method doesn't seem to be called upon a tap, and I don't know if even if it gets called will dismiss the keyboard. Any help will be appreciated.

• gwt not showing the right image

  - by arinte

  I have a gwt image object . In my code I set my visibleRect like this: btnSearch.setVisibleRect(-64,-80,16,16); So when I run my code with firebug the html looks like this: <img border="0" style="width: 16px; height: 16px; background: url(&quot;http://tempest/deltaflow/Content/Images/icon.png&quot;) no-repeat scroll 64px 80px transparent;" src="http://127.0.0.1:8888/trunkui/clear.cache.gif"> Why is the '-' left off? When I edit it with firebug to have the '-' it works fine.

• Laptop screen turns off on removing power cord

  - by YatharthROCK

  After a recent upgrade to Windows 8.1 Pro from W8, my laptop's screen turns off as soon as you remove the power cord. It turns back on with no issues when you plug the power back in. Keyboard and mouse input is processed while the screen is off. My settings tell the screen to go off after 2 minutes of inactivity on battery. I was having a battery issue from before where my laptop would should down after 5 minutes of running on battery (despite showing 60% left), but I think that's unrelated. Any other info will be provided on request. Can anyone help me figure out what's going on? How can I stop this behaviour?

• How to resize a silverlight control to a full webpage.

  - by ForeverDebugging

  I'm currently using a datagrid within a user control. The datagrid resizes based on the number of rows, and therefore goes off the webpage. I've tried wrapping the control around a ScrollViewer, but in order to have the scroll bar visible and working, I need to set the MaxHeight of the datagrid. The problem is that I don't know what the MaxHeight of the datagrid should be because it differs based on the size of the browser window appearing on the screen. Any suggestions on how to determine the correct size of the control?

• Different background colors for the top and bottom of a UITableView

  - by Aaron Brethorst

  If you look at your Inbox in iPhone OS 3.0's Mail app, you'll see that swiping down displays a grayish background color above the UISearchBar. Now, if you scroll down to the bottom of the table, you'll see that the background color at that end is white. I can think of a couple ways of solving this problem, but they're pretty hacky: Change the table view's background color depending on the current scrollOffset by overriding -scrollViewDidScroll: Give the UITableView a clear background color and then set its superview's backgroundColor to a gradient pattern image. Does anyone know what the "best practice" solution is for this problem? thanks.

• startx error no desktop manager

  - by WikiWitz

  I have Backtrack 5R2 KDE. I started recovery mode and did a failsafe xorg configuration. After that, I cannot load the KDE manager when I enter the startx command after logging in. Whenever I do a startx command (as root), the result resembles the following: This is not the actual output (I just drew this with MS paint because I cannot do a printscreen). The screen is just black with the icon in the upper left corner. The other pop-up menu appears when left-clicking the mouse. I tried the cp xorg.conf.failsafe xorg.conf advice from other websites with no luck. I have also tried the 'reconfigure option(s)' form the recovery mode with no success.

• Internet explore is unresponsive while loading a large page

  - by kdhamane

  We have a html page being rendered in the browser (IE) that causes the browser to hang. The page is generated through server side script (ASP.NET and viewstate is disabled). The page while loading takes a long time (its not a b\w issue since we can reproduce it on local machine) and sometimes results in script unresponsive error. On debugging the issue we found that the html size on the client side is 4.73 MB. There's also a lot of DOM traversal (using JQuery) after document is ready (jquery-document.ready). After loading as well, the page simply hangs on any user interaction (scroll, mouseover) etc. A CPU usage spike (25-50% usage) is seen during loading and on any user interaction

• How to pull a RANDOM and UNIQUE record from SQL via LINQ.

  - by Jeremy H

  Okay, I found lots of posts on SO about how to pull a RANDOM item from the database when using LINQ. There seems to be a couple of differnet ways to handle this. What I need to do though is pull a RANDOM item from the database that the user has not seen before. The data I am pulling from the database is very small. Is there any way I can just hit the database once for 1000 records and then randomly scroll through those? Should I put a cookie on the users system recording the IDs of which items they have seen, pull a random record, check to see if it is seen and if so, pull from the database again? That seems like performance issues just waiting to happen. I don't expect anyone to code it for me, I am just looking for concepts and pointing in the right direction of how I should go about this. Need more details? Just let me know!

• The framerate of one movieclip slowly declines over time. What could cause this? [Flash CS3]

  - by Miles

  I'm creating a flash rhythm game. I have a looping (at a certain frame I have a gotoAndPlay) movieclip that represents the notes that scroll by, which plays for about three minutes. As the level progresses, the movieclip's framerate begins to lag and stutter. I have no idea how this could occur. It is also worth mentioning that the notes are represented by text, if that makes any difference. As far as posting my code goes, I think it would be far too convoluted to be worth your time. And I think it could be a simple problem. I just don't understand how the framerate of this movieclip could drop independent of the rest of the game.
