• Getting Google repositories to work with apt-get on Ubuntu Hardy

  - by Justin

  I've installed Google Chrome on Hardy via the .deb file and would like to configure apt-get for automatic updates. [I have another machine running Ubuntu Karmic where this works fine; apt-get knows the package as 'google-chrome'; I'm now using a Dell Mini 10 with Ubuntu 8.04 LTS installed] As part of the .deb install, two entries have been added to the third- party software sources tab: http://dl.google.com/linux/deb stable main http://dl.google.com/linux/deb stable non-free main However if I check for updates with either of these clicked, I get the following error: Failed to fetch http://dl.google.com/linux/deb/dists/stable/Release Unable to find expected entry main/binary-lpia/Packages in Meta-index file (malformed Release file?) There is a thread here which indicates others have had the same problem: http://www.google.co.uk/support/forum/p/Chrome/thread?tid=097d103f87b49abe&hl=en This references a further thread: http://code.google.com/p/chromium/issues/detail?id=38608 which suggests the problem has been fixed. Despite this I remain unable to get it to work, and none of the suggested workarounds seem to work either. Ideas ? Thanks.

• Panel in Windows Forms Application not clearing

  - by SwiftStriker00

  I'm working on my project: [Beer Pong Management System][1], a Windows Forms application. I am currently trying to add a whole tournament mode to it. In a nutshell, I've created a TabControl, with the first tab page with the settings and setup and the second page the brackets. There is a feature for each of the match-ups, that once there is a winner is decided, a yellow cancel button will appear in order to revert the tournament. However my issue is when i click the button the next match-up does not get removed in the series is going. See below: Image Here(not high enough rep to insert image) I have tried to set the MatchUp to null, I've tried dispose(), close(). even Parent.Controls.Remove(). Even after I switch tabs which is supposed to clear all, they still sit there when i come back. I have a feeling I might be loosing a reference or something because I can't even push new teams into them, they just sit there with their buttons. Does anyone have any tips or know of any known issues that might be causing this? Thanks. [1] _http://www.cs.rit.edu/~rmb1201/pages/code.shtml

• Uniq in awk; removing duplicate values in a column using awk

• Python programming - Windows focus and program process

  - by Zack

  I'm working on a python program that will automatically combine sets of files based on their names. Being a newbie, I wasn't quite sure how to go about it, so I decided to just brute force it with the win32api. So I'm attempting to do everything with virtual keys. So I run the script, it selects the top file (after arranging the by name), then sends a right click command,selects 'combine as adobe PDF', and then have it push enter. This launched the Acrobat combine window, where I send another 'enter' command. The here's where I hit the problem. The folder where I'm converting these things loses focus and I'm unsure how to get it back. Sending alt+tab commands seems somewhat unreliable. It sometimes switches to the wrong thing. A much bigger issue for me.. Different combination of files take different times to combine. though I haven't gotten this far in my code, my plan was to set some arbitrarily long time.sleep() command before it finally sent the last "enter" command to finish and confirm the file name completing the combination process. Is there a way to monitor another programs progress? Is there a way to have python not execute anymore code until something else has finished?

• selenium and firefox timeout behavior

  - by Md. Reazul Karim

  I am facing this strange timeout behavior. I tried to load some page using: WebDriver drv = new FirefoxDriver(); drv.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); drv.get(url); String email = ""; try { WebElement aElem = Util.safeFindElementByXpath(drv, "//p[1]/a[1]"); if (aElem != null) { email = aElem.getAttribute("href"); } } catch (Exception e) { } drv.quit(); return email; The safeFindElementByXpath is: static WebElement safeFindElementByXpath(WebDriver driver, String xpath) { try { return driver.findElement(By.xpath(xpath)); } catch (NoSuchElementException e) { return null; } } Now I set the firefox network.http.connection-timeout and network.http.connection-retry-timeout both to 10. Now if I restart the firefox I can see the new values. But if I try to run the above code - the firefox window opens and it waits for a particular website for a long time. Hence I open another tab in the same firefox window and check the values of timeout and find them to be 90 and 250. If I change the values on that same window, the selenium code immediately finishes requesting for the page (ie it goes after the exception block). So the thing is that the same code will work on many sites and I don't know beforehand which site is invalid/down and I was thinking of putting this code in a separate thread and kill the thread after some time from the calling thread. But that is not possible I guess because the child thread has no way to poll anything as it is stuck at page request and can't go to the polling code afterwards. Now the thing is that I want any kind of hack/workaround to accomplish this: try getting the emails for good sites and if there are bad sites just give up after a certain period (press the panic button sorta thing). Thanks

• Getting hover text with selenium in java

  - by BinaryEmpire

  I am trying to figure out how to get the product availability text from a page like http://www.walmart.com/browse/TV-Video/TVs/_/N-96v3? (once a store has been selected) I selected 76574 as my zipcode and went to the "In My Store" tab The code I have now is WebElement hoverElement = driver.findElement(By.xpath(".//*[@id='Body_15992428']/span")); WebElement hidden = driver.findElement(By.xpath(".//*[@id='slapInfo_NoVariant_15992428']/div")); Actions builder = new Actions(driver); builder.clickAndHold(hoverElement).build().perform(); System.out.println(hidden.getText()); **Edit: I tried profile.setEnableNativeEvents(false); and the text is now displayed in the automated browser window. I still cannot get to the text I want though. It does not throw an exception, only displays nothing because the driver thinks its still hidden. Any one know how to fix this? I keep getting Exception in thread "main" org.openqa.selenium.InvalidElementStateException: Cannot perform native interaction: Could not load native events component. Even after I do profile.setEnableNativeEvents(true); Are there any other ways I can get the hidden text, or what am I doing wrong here? Additionally while I was inspecting the code with firebug, I saw that there is this code <script type="text/javascript"> WALMART.$(document).ready(function(){ WALMART.$('#Body_15992428').hover(function(){ WALMART.$('#SeeStoreAvailBubble').wmBubble('update',WALMART.$('#bubbleMsgUpdate_15992428').html()); }); }); </script> I dont really know how to do things directly with javascript but is there is any way of getting the message text directly from that with a javascript executor?

• facebook comments ajax

  - by Shunsho

  I have a function that load a jquery ui accordion (differents accordions based on different id) When I click on the tab titled "Facebook Comments" I do: $("#myaccordion").bind('accordionchange', function(event, ui) { id = $("#myaccordion").data('id'); switch (ui.newHeader.text()) { case "Facebook Comments": displayFb(id); break; } }); The "displayFB" function is: function displayFb(id){ $.get('/fbcomments/' + id, function(data) { $("#facecomm").append(data); }); } Where www.myweb.com/fbcomments/id is: <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/es_ES/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> <div class="fb-comments" data-href="<?php echo '/fbcomments/'.$id ?>" data-num-posts="10" data-width="220"></div> When I load the homepage, then choose an accordion, then open a Facebook Comments, it works perfect. If I reload the page and choose another accordion, work perfect again. The problem is when I choose another accordion or the same again without reload the whole page. The accordions loads very well, all the data on them (some tabs of images, text, videos, etc), but the facebook comments don't appear. I tried: loading the #fb-root and facebook comment <script> on the main layout....doesn't work. adding FB.XFBML.parse(); into displayFB function....doesn't work adding FB.XFBML.parse(); into a $(document).ready(function(){} ...doesn't work. Thank you for reading and try to help!!

• threading in Python taking up too much CPU

  - by KevinShaffer

  I wrote a chat program and have a GUI running using Tkinter, and to go and check when new messages have arrived, I create a new thread so Tkinter keeps doing its thing without locking up while the new thread goes and grabs what I need and updates the Tkinter window. This however becomes a huge CPU hog, and my guess is that it has to do somehow with the fact that the Thread is started and never really released when the function is done. Here's the relevant code (it's ugly and not optimized at the moment, but it gets the job done, and itself does not use too much processing power, as when I run it not threaded, it doesn't take up much CPU but it locks up Tkinter) Note: This is inside of a class, hence the extra tab. def interim(self): threading.Thread(target=self.readLog).start() self.after(5000,self.interim) def readLog(self): print 'reading' try: length = len(str(self.readNumber)) f = open('chatlog'+str(myport),'r') temp = f.readline().replace('\n','') while (temp[:length] != str(self.readNumber)) or temp[0] == '<': temp = f.readline().replace('\n','') while temp: if temp[0] != '<': self.updateChat(temp[length:]) self.readNumber +=1 else: self.updateChat(temp) temp = f.readline().replace('\n','') f.close() Is there a way to better manage the threading so I don't consume 100% of the CPU very quickly?

• Distinct() to return List<> returning Duplicates

  - by KDM

  I have a list of Filters that are passed into a webservice and I iterate over the collection and do Linq query and then add to the list of products but when I do a GroupBy and Distinct() it doesn't remove the duplicates. I am using a IEnumerable because when you use Disinct it converts it to IEnumerable. If you know how to construct this better and make my function return a type of List<Product> that would be appreciated thanks. Here is my code in C#: if (Tab == "All-Items") { List<Product> temp = new List<Product>(); List<Product> Products2 = new List<Product>(); foreach (Filter filter in Filters) { List<Product> products = (from p in db.Products where p.Discontinued == false && p.DepartmentId == qDepartment.Id join f in db.Filters on p.Id equals f.ProductId join x in db.ProductImages on p.Id equals x.ProductId where x.Dimension == "180X180" && f.Name == filter.Name /*Filter*/ select new Product { Id = p.Id, Title = p.Title, ShortDescription = p.ShortDescription, Brand = p.Brand, Model = p.Model, Image = x.Path, FriendlyUrl = p.FriendlyUrl, SellPrice = p.SellPrice, DiscountPercentage = p.DiscountPercentage, Votes = p.Votes, TotalRating = p.TotalRating }).ToList<Product>(); foreach (Product p in products) { temp.Add(p); } IEnumerable temp2 = temp.GroupBy(x => x.Id).Distinct(); IEnumerator e = temp.GetEnumerator(); while (e.MoveNext()) { Product c = e.Current as Product; Products2.Add(c); } } pf.Products = Products2;// return type must be List<Product> }

• VS2010 + IE8 Debugging woes - Element not found

  - by Chin

  I am having great difficulty trying to debug with vs2010 and IE8, though I think the problem is more IE8 specific. When starting a debug session 9 times out of 10 I will have the following problem. IE tab says connecting.. - then after a 5 second wait I will get an error in VS saying element not found. Even when I click ok to dismiss the error, the IE window still shows connecting... I will then have to kill the IE process to be able to close IE to try again. Sometimes however I am lucky and it starts. But the whole thing is so random I have no clue where to start. One thing I have noticed is that I always have 2 IE processes started even though there is only one window open. One has a small footprint of 100k, I presume it is some kind of helper. I am using a static port with the built in WebDev server. If anyone has had similar problems please let me know how you resolved it. Its driving me nuts! thanks

• Sorting a very large text file in Java

  - by Alice

  Hi, I have a large text file I need to sort in Java. The format is: word [tab] frequency [new line] The algorithm for sorting is: Read some of the file, filtering for purlely alphabetic words. Once you have X number of alphabetic words, call Collections.sort and write the result to a file. Repeat until you have finished reading the file. Start reading two sorted files, comparing line by line for the word with higher frequency, and writing at the same time to a new file as to not load much into your memory Repeat until all files are merged into one large file Right now I've divided the large file into smaller ones (sorted by descending frequency) with 10,000 lines each. I know I need to somehow merge these files back together, but I'm not sure how to go about this. I've created a LinkedList to keep track of all the files created. The algorithm says to compare each line in the two files, except I've tried a case where , say file1 = 8,6,5,3,1 and file2 = 9,8,8,8,8. Then if I compare them line by line I would get file3 = 9,8,8,6,8,5,8,3,8,1 which is incorrectly sorted (they should be in decreasing order). I think I'm misunderstanding some part of the algorithm. If someone could point out what I should do instead, I'd greatly appreciate it. Thanks. edit: Yes this is an assignment. We aren't allowed to increase memory unfortunately :(

• UITableView overlaps with NavigationBar in Storyboard Setting on first run

  - by Evils

  I know this seems to be a duplicate question which has been around here many many times, but believe me, I tried all iOS7 and earlier fixes which sets the Layout to a different Edge configuration without any change. My Storyboard looks like this: -> Navigation Controller -> Tab Bar Controller -> MyTableViewController -> VCForCellOne With the first run of my application the UITableView overlaps with the source NavigationController as shown here: After clicking on one of my Cells which pushes the corresponding ViewController to the NavigationController and going back again, everything looks fine as shown here: So everything is as it should be after once pushing another ViewController to the NavigationController and then going back. Switching from Portrait to Landscape and back also fixes the layout problem and everything is layed out as it should be. My ViewController within the Storyboard looks like this: I left it the default value, so I don't know what goes wrong here. I hope you understand my problem here. There's no custom class ViewController here, so no additional code which messes up something here. Any help highly appreciated!

• Choosing between Facebook iframe scrollbar or page cut off halfway

  - by pg.

  I have an iframe tab in facebook. I used "overflow:hidden" in the body tag and this code at the bottom of my page: <div id="fb-root"></div> <script type="text/javascript"> window.fbAsyncInit = function() { FB.init({ appId : 'MY_APP_ID', status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true // parse XFBML }); FB.Canvas.setAutoResize(100); }; (function() { var e = document.createElement('script'); e.async = true; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; document.getElementById('fb-root').appendChild(e); }()); </script> This removes the scrollbars and resizes the iframe. The problem is that my page is cut off after about 800px (that leaves about 400px). I've set the height in facebook to "fluid". It works absolutely fine in every other browser but not in IE8. As a side question, why does IE still exist? It's the absolute worst thing. Anyways, I added this to the head: <!--[if IE]> <style> body{overflow-y:scroll;} </style> <![endif]--> But that just gets me back to having the scrollbars again.

• Should I really use a UITableView in this situation?

  - by mystify

  Imagine you have a view like this: At the top, there is an UISegmentedControl with two segments. It functions like a tab. Pressing one segment will activate this particular content below that UISegmentedControl. Below the UISegmentedControl are some switches. These modify the way how the content should be rendered. And finally, below those switches, there's a table. Imagine a table not in sense of UITableView, but just what it really is: A table. It shows little messages like twitter messages or chat messages for example, one below the other. Like you know it from skype and other chats. Basically they're just rows with some formatting. A label, some image views, some lines, a background. Pretty basic. The data comes from an array. No core data. The whole thing including the segmented control and setup switches must be scrollable. So what I did is: I put all this stuff in an UIScrollView. Now I have to make the decision if I would use a UITableView inside there for that table part, or if I would just print a lot of rows on to the scroll view (with -drawRect:). But some problems stick in my head: Can I put a UITableView inside a UIScrollView? I assume this makes a lot of problems. I don't want that the table part is separately scrollable. Again imagine that view: First there are some basic choice things (segmented control, switches). Then there comes the table. When you scroll, the whole thing scrolls. That's mainly because this first part with the settings can be pretty big, so you would want to scroll it away. The next thing is: Can I customize UITableView in such a way, that it consists of two parts? One for that settings part, and one for the actual data to display?

• Deleting unneeded rows from a table with 2 criteria

  - by stormbreaker

  Hello. I have a many-to-many relations table and I need to DELETE the unneeded rows. The lastviews table's structure is: | user (int) | document (int) | time (datetime) | This table logs the last users which viewed the document. (user, document) is unique. I show only the last 10 views of a document and until now I deleted the unneeded like this: DELETE FROM `lastviews` WHERE `document` = ? AND `user` NOT IN (SELECT * FROM (SELECT `user` FROM `lastviews` WHERE `document` = ? ORDER BY `time` DESC LIMIT 10) AS TAB) However, now I need to also show the last 5 documents a user has viewed. This means I can no longer delete rows using the previous query because it might delete information I need (say a user didn't view documents in 5 minutes and the rows are deleted) To sum up, I need to delete all the records that don't fit these 2 criterias: SELECT ... FROM `lastviews` WHERE `document` = ? ORDER BY `time` DESC LIMIT 10 and SELECT * FROM `lastviews` WHERE `user` = ? ORDER BY `time` DESC LIMIT 0, 5 I need the logic. Thanks in advance.

• JS file called twice in Wordpress

  - by Dxr Tw

  I'm trying to reduce number of requests by reducing number of JS files on WP site. I successfully combined around 7 javascript files into one (site.js). Now, I'm using a plugin which has its own JS file (pluginA.js), I want to include (pluginA.js) in that site.js. However, if I simply copy pluginA JS content to site.js and then change location to /files/site.js, firebug's NET tab shows that site.js is requested/called twice. I presume this is due to wp_enqueue_script. How can I make it not call site.js second time but just look into already loaded site.js? Maybe there's alternative to wp_enqueue_script? Plugin's php file: add_action( 'wp_enqueue_scripts', 'testplugin_scripts'); function testplugin_scripts() { /*global $testplugin_version; */ $default_selector = 'li:has(ul) > a'; $default_selector_leaf = 'li li li:not(:has(ul)) > a'; wp_enqueue_scripts('test-plugin', site_url('/files/site.js', __FILE__), array('jquery'), $testplugin_version); $params = array( 'selector' => apply_filters('testplugin_selector', $default_selector), 'selector_leaf' => apply_filters('testplugin_selector_leaf', $default_selector_leaf) ); wp_localize_script('test-plugin', 'testplugin_params', $params); }

• Best way and problems when using ajax tabs with an MVC PHP project

  - by Jonathan

  Hi, I'm building an IMDB.com like website using PHP/jQuery and a MVC approach (no OOP). I have an index.php base controller to 'rule them all' :), a controllers folder with all the controllers, a models folder and a view folder. In some pages of the website I have tabbed navigation, when the visitor clicks on one of those tabs to get more information, jQuery gets that data using the $.post or $.get method and shows it on the tab container, obviously without refreshing the page. The problem is that those pages loaded by ajax are also generated using controllers, models, and views, and the things are getting a bit complicated for someone like me ( = 'no experience'). To dynamically get the data I some times need to include a model twice, include an include in an include in an include, send information multiple times, connect with the database again, and all sort of things like that and I'm sure there is a better and prettier way to do this. I'm searching for the best approach and common methods for this. I have no experience working with a big project like this. This is a personal project so I have full control and every answer is welcome. Thanks!!!

• problem after uploading file to web host

  - by Alexander

  I have a .xml file in my App_Data folder, I can access it fine in my localhost, however after uploading it to my webhost I got the following: ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access. So who should I grant access to read? There's 3 user in my web host and all seems to have read access set to them.. one is NETWORK_SERVICE, IUSR_MACHINENAME and my user. So what is wrong?

• .htaccess redirect noticably increasing load time

  - by GTCrais

  I set up a SEF link via .htaccess RewriteRule to one of the articles on my website just to see how that works, and it does work but it considerably increases the load time of that particular page. On average the articles (including the one I'm talking about, when not using the rewrite rule) load in about 1.3 seconds. With the rewrite rule, the load time is 3.3 seconds on average until the page displays, and the loader thingy in the firefox tab keeps spinning for another 2 seconds. I have WAMP setup on my computer, and the website is being accessed through no-ip.com. Here is the .htaccess config (very simple, as you can see): Options +FollowSymLinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^o-sw-liji /NewSWL/o-nama.php?body=o-sw-liji In httpd.conf I have this (somewhere I read this might affect the load time for some reason - searching for files through all the directories or something, I don't remember exactly what I read): <Directory /> Options None AllowOverride None Order deny,allow Deny from all </Directory> DocumentRoot "Z:/Program Files (x86)/wamp/www/" <Directory "Z:/Program Files (x86)/wamp/www/"> Options None AllowOverride All Order allow,deny Allow from all </Directory> Any ideas why .htaccess redirect increases the load time by so much? UPDATE: so I put a session based counter in the "o-nama.php" script. Apparently when I access the web via the 'normal' link i.e. 'o-nama.php?body=o-sw-liji', the counter increases by one, as it should - it's one page load. But when the page is accessed through the redirected link, i.e. 'o-nama/o-sharewood-liji' the counter increases by 6-8, which naturally makes the load time a lot longer, since it's loading the same page for 6-8 times. I have no idea why this is happening. Any help is appreciated.

• How to save enum settings in Visual Studio project properties?

  - by zaidwaqi

  Hi, In the Settings tab in Visual Studio, I can see Name, Type, Scope, Value table. Define settings is intuitive if the data type is already within the Type drop-down list i.e. integer, string, long etc. But I can't find enum anywhere. How do I save enum settings then? For now, I have the following which clutter my code too much. public enum Action { LOCK = 9, FORCED_LOGOFF = 12, SHUTDOWN = 14, REBOOT, LOGOFF = FORCED_LOGOFF }; and I define Action as int in the setting. Then I have to do, switch (Properties.Settings.Default.Action) { case 9: SetAction(Action.LOCK); break; case 12: SetAction(Action.FORCED_LOGOFF); break; case 14: SetAction(Action.SHUTDOWN); break; case 15: SetAction(Action.REBOOT); break; default: SetAction(Action.LOCK); break; } Would be nice if I could simply do something like SetAction(Properties.Settings.Default.Action); to replace all above but I dont know how to save enum in setting. Hope my question is clear. Thanks.

• iphone: re-sizing gradient after shift from portrait to landscape

  - by d_CFO

  In viewDidLoad, I can create a gradient with no problem: CAGradientLayer *blueGradient = [[CAGradientLayer layer] retain]; blueGradient.frame = CGRectMake(gradientStartX,gradientStartY,gradientWidth,gradientHeight); where gradientWith is device-defined as 320 or 1024 as appropriate. What I can’t do is resize it inside willRotateToInterfaceOrientation: -– and thus get rid of that empty black space off to the right -- after the user changes to landscape mode. (The nav bar and tab bar behave nicely.) (1) Recalibrating the gradient’s new dimensions according to the new mid-point, (2) using kCALayerMaxXMargin, and (3) employing bounds all looked like they would do the job. bounds looked a litte more intuitive, so I tried that. I don’t want to admit that I have made zero progress. I will say that I’ve been reduced to the brute force method of trying every permutation of self, view, layer, bounds, blueGradient, and CGRect(gradientStartX,gradientStartY,newGradientWidth,newGradientHeight) with zero success. This is not difficult. My lack of understanding is making it difficult. Anyone out there “Been there, done that”?

• Which Java debugger do *you* use.

  - by mikevdg

  I spend a lot of time debugging applications in Eclipse using JPDA. There are a few issues with the Eclipse debugger which really annoy me. Can anybody recommend plug-ins, better debuggers or perhaps tricks that I don't know of yet? In the "Variables" tab, you can type in and execute bits of Java code. However, you first need to click on something (I usually click on "this") to give it some context. Then, after you've typed in a lengthy Java expression to debug something and "execute" it, your expression gets replaced with the result, so you need to type it in all over again. Is there some better way, such as a console or something that I'm missing? When you're poking through data structures, the presentation in the debugger leaves much to be desired. You see the internal representation of Lists, Maps, StringBuilders etc. What I want to see is what these objects conceptually contain. Is there a way of doing this, perhaps using some other debugger, or an extension or something? When an Exception is thrown, is there some way of inspecting the state of the application where the Exception was thrown? Currently I need to set breakpoints just before the Exception occurs and then try to reproduce it. When I'm stepping over a line with many statements on it, I can't actually see which of those statements is being executed, except by "stepping in" to each one to see where it takes me. If no source code is found, Eclipse just stares blankly at you. You get a helpful screen saying "Class File Editor / Source code not found" which is completely useless. I'd much prefer to be able to step through the bytecodes so I can at least see what is going on. Does anybody know of a Java debugger that does this better than Eclipse?

• How to make a piece of WPF content take up the entire application window

  - by Bojin Li

  I'm working on an application that contains a number of content areas. I want to implement a behavior such that in response to user input, any of these content areas can be toggled to fit the entire application window, and optionally back to its original position again. I experimented with several approaches and none of them seem optimal for me. Here's what I tried to do: Use the ClipToBoundsProperty on the content I want to make "Full Screen": Doesn't work because only the CanvasPanel seems to fully respect this property. The application need to be localized so I would really like to avoid the CanvasPanel. Use a Grid and collapse the other content areas, such that only the one I want to see is visible, hence taking up the entire screen: This will probably work but doesn't seem easy to implement nor maintain. The "Full Screen" content area could be several levels deep, for example residing inside a Tabcontrol, so I would have to hide the tab headers too etc. Reconstruct the content area in a separate view and display it while hiding the rest: Seems easy enough to do with DataTemplates and my ViewModel objects, but any GUI/View only states are not preserved using this approach. Somehow "lift" the GUI/View I want to "Full Screen" into the separate view and display it while hiding the rest: I don't know how to do this or even if this is possible. Anyway if anyone knows a better approach I would love to know about it. Thanks a lot!

• Is there a better way to detab (expand tabs) using Perl?

  - by Uri

  I wanted to detab my source files. (Please, no flame about WHY I wanted to detab my sources. That's not the point :-) I couldn't find a utility to do that. Eclipse didn't do it for me, so I implemented my own. I couldn't fit it into a one liner (-e) program. I came with the following, which did the job just fine. while( <> ) { while( /\t/ ) { s/^(([^\t]{4})*)\t/$1 /; s/^((([^\t]{4})*)[^\t]{1})\t/$1 /; s/^((([^\t]{4})*)[^\t]{2})\t/$1 /; s/^((([^\t]{4})*)[^\t]{3})\t/$1 /; } print; } However, it makes me wonder if Perl - the champion language of processing text - is the right tool. The code doesn't seem very elegant. If I had to detab source that assume tab=8 spaces, the code would look even worse. Specifically because I can think of a deterministic state machine with only 4 states to do the job. I have a feeling that a more elegant solution exists. Am I missing a Perl idiom? In the spirit of TIMTOWTDI I'm curious about the other ways to do it. u.
