• VS2008 - Find and Replace - Searches too many files.

  - by Pam Bullock

  I've used VS2008 a lot and have never had this problem. However, I started a new job and am using a new machine. Ever since I've gotten here the VS Find feature has been acting funny. I first noticed it when I did a replace all for "All Open Files". The project wouldn't build because the values had actually been replaced in other files within the solution that were not open and didn't even open after I pressed replace all. I have found that I can never use replace all on this machine because I never know what it is going to do. Even if I just do a find on "Current Document", once it's done with the document and I should get that message that says "No more matches found" it actually OPENS another random file from my solution where there is a match and keeps on going. It seems to never make any difference what "Look in" option I've chosen. My coworker has an install off the same disk and claims to not be experiencing this. We're in the middle of a stressful, huge project with a close deadline so I know my boss won't let me do a reinstall. Has anyone else ever had this happen? Anyone know a fix?? Thanks, Pam

• Select box is not working properly after including google custom search box in web page

  - by Vinay

  I have got a select box and google custom search box in a page, when i choose a option from select box and navigate away from the page and again if i come back to the same page the option will not be selected (violates the default functionality of select box), The code is below <script src="https://www.google.com/jsapi" type="text/javascript"></script> <script type="text/javascript"> google.load('search', '1', {language : 'en'}); google.setOnLoadCallback(function() { var customSearchControl = new google.search.CustomSearchControl('004920913350056953771:kpkclvhujzk'); customSearchControl.setResultSetSize(google.search.Search.FILTERED_CSE_RESULTSET); var options = new google.search.DrawOptions(); options.setAutoComplete(true); options.enableSearchboxOnly("<?=$homeurl?>my_results.php", "query"); customSearchControl.draw('cse-search-form', options); }, true); </script> <select multiple="yes"> <option>1</option> <option>2</option> </select> If i remove the custom search script, the select box selected option will be retained even after navigating away from the page. (default functionality) Its working fine in chrome, IE but not in Firefox. Is there any solution for this, so that select box must work fine even in the presence of search box, but the order must be same 1) Search box 2)Select Box

• Strange EListError occurance (when accessing variable-defined index)

  - by michal

  Hi, I have a TList which stores some objects. Now I have a function which does some operations on that list: function SomeFunct(const AIndex: integer): IInterface begin if (AIndex > -1) and (AIndex < fMgr.Windows.Count ) then begin if (fMgr.Windows[AIndex] <> nil) then begin if not Supports(TForm(fMgr.Windows[AIndex]), IMyFormInterface, result) then result:= nil; end; end else result:= nil; end; now, what is really strange is that accessing fMgr.Windows with any proper index causes EListError... However if i hard-code it (in example, replace AIndex with value 0 or 1) it works fine. I tried debugging it, the function gets called twice, with arguments 0 and 1 (as supposed). while AIndex = 0, evaluating fMgr.Windows[AIndex] results in EListError at $someAddress, while evaluating fMgr.Windws[0] instead - returns proper results ... what is even more strange, even though there is an EListError, the function returns proper data ... and doesn't show anything. Just info on two EListError memory leaks on shutdown (using FastMM) any ideas what could be wrong?! Thanks in advance michal

• Issue in creating Zip file using glob.glob

  - by infosyssec

  Hi, I am creating a Zip file from a folder (and subfolders). it works fine and creates a new .zip file also but I am having an issue while using glob.glob. It is reading all files from the desired folder (source folder) and writing to the new zip file but the problem is that it is, however, adding subdirectories, but not adding files form the subdirectories. I am giving user an option to select the filename and path as well as filetype also (Zip or Tar). I don;t get any problem while creating .tar.gz file, but when use creates .zip file, this problem comes across. Here is my code: for name in (Source_Dir): for name in glob.glob("/path/to/source/dir/*" ): myZip.write(name, os.path.basename(name), zipfile.ZIP_DEFLATED) myZip.close() Also, if I use code below: for dirpath, dirnames, filenames in os.walk(Source_Dir): myZip.write(os.path.join(dirpath, filename) os.path.basename(filename)) myZip.close() Now the 2nd code taks all files even if it inside the folder/ subfolders, creates a new .zip file and write to it without any directory strucure. It even does not take dir structure for main folder and simply write all files from main dir or subdir to that .zip file. Can anyone please help me or suggest me. I would prefer glob.glob rather than the 2nd option to use. Thanks in advance. Regards, Akash

• TeamCity + HG. Only pull (push?) passing builds

  - by ColoradoMatt

  Feels like with the popularity of continuous integration this one should be a piece of cake but I am stumped. I am setting up TeamCity with HG. I want to be able to push changesets up to a repository that TeamCity watches and runs builds on changes. That's easy. Next, if a build passes, I want that changeset to be pulled into a "clean" repository... one that contains only passing changesets. Should be easy but... TeamCity 6 supports multiple build steps and if any step fails, the rest don't run. My thought was to put a build step at the end that does a pull (or optionally a push?) to get the passing changeset into the clean repository. I am trying to use PsExec to run hg on the box with the repositories. If I try to run just a plain 'hg pull' it can't find the hg.exe even though it is set in the path and I have used the -w flag. I have tried putting a .bat file in the clean repository that takes a revision parameter and it works fine... locally. When I try to run the .bat file remotely (using PsExec) it runs everything fine but it tries to run it on the build agent. Even if I set the -w argument it runs the .bat file there but tries to run the contents on the build agent box. Am I just WAY off in my approach? Seems like this is a pretty obvious thing to do so either my Google skills are waning or no one thinks this is worthy of writing about. Either way, I am stuck in SVN land trying to get out so I would appreciate some help!

• Inserting script from jQuery / Javascript

  - by Colby77

  Hi, I'm trying to insert reCaptcha code into my page from jQuery, but it doesn't work. Here is my code: $("#button").click(function() { $("#loginBox").html($.getRecaptcha()); }) When I try the following, my code doesn't even run. I think it's trying to execute instead of rendering it. $.getRecaptcha = function(){ return '<script type="text/javascript"' + 'src="http://api.recaptcha.net/challenge?' + 'k=6Ld3iAsAAAAAAGyX8QT244GagPEpCDSD-96o4gEi"></script>'; } With the following, the code runs, but when I click to #button I get an empty, full white browser window. $.getRecaptcha = function(){ var captcha = $("<script>") .attr("type", "text/javascript") .attr("src", "http://api.recaptcha.net/challenge?k=6Ld3iAsAAAAAAGyX8QT244GagPEpCDSD-96o4gEi"); return captcha; } I don't want to insert reCaptcha code into my html from the beginning, because it downloads the reCaptcha content from the reCaptcha server even if my users don't want to use it. I could set the visibility of the container that holds the reCaptcha to invisible (display: none;), but it will dowload the content irrespectively of it. I can insert the "noScript" code that reCaptcha gives us, but it doesn't work either, because it can spot that the browser allow javascript but I use noScript. Any suggestions? (I know I put my public reCaptcha key into the code, but it is just for testing purposes, and you could get it from my html or javascript code anyway)

• Do the new NoPIA and Type Equivalence features in C#/.NET 4.0 mean Microsoft.mshtml.dll is no longer

  - by jpierson

  I'm maintaining a WPF based application which contains a WinForms based WebBrowser control that based on the IE web browser control. When we deploy, we have had to also supply Microsoft.mshtml.dll and do some custom configuration stuff for our ClickOnce publishing process as well in order to get things to work. I'm curious that with the new NoPIA and Type Equivalence features and dynamic type capabilities in C# 4.0 can we expect that if we upgrade that we can remove the dependencies on the Microsoft.mshtml.dll assembly? If so this will not only reduce the size of our deployment quite a bit but will also simplify our publishing process as well. It is my understanding that we should be able embed the types that normally get automatically generated into extra assemblies for COM types such as the MapPoint Control by Visual Studio. I don't know if this also applies to the Microsoft.mshtml.dll or even how it is done even in the most simple of cases. If somebody could provide an explanation about what the practical impact of these new features are on a project that relies on COM interop and especially the Microsoft.mshtml.dll assembly it would be of great help to me.

• Button Visibility Converter

  - by developer

  Hi All, I have a requirement wherein I need to display on a User form, a Create Button if that user has doesnt have a profile and a Edit Button if he does have a profile. I am using a converter to change the visibility of the button. Below is my code, <StackPanel Orientation="Horizontal"> <Button Content="Create Profile" Visibility="{Binding Profile,Converter={StaticResource ButtonVisibilityConverter}, ConverterParameter='Create'}" Command="local:LaunchEditor" CommandParameter="{Binding}"/> <Button Content="Edit Profile" Visibility="{Binding Profile,Converter={StaticResource ButtonVisibilityConverter}, ConverterParameter='Edit'}" Command="local:LaunchEditor" CommandParameter="{Binding}"/> </StackPanel> Below is my converter code public class ButtonVisibilityConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { string btName = null; btName = (string)parameter; if ((value==null)&&(btName=="Create")) { return Visibility.Visible; } else if ((value != null) && (btName=="Edit")) { return Visibility.Visible; } else { return Visibility.Collapsed; } } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } Everything works fine initially, but the moment I click on the Create Profile window, and it is the constructor that loads the profile window, after that even if I close that window without doing anything, the Create button turns to edit. My guess is that, it is because the constructor would have create the profile object and so even though the object is empty it shows me edit button instead of create. Is there any other way I could display button visibility??

• moving a sprite causes jerky movement

  - by mac_55

  I've got some jerky movement of my sprite. Basically, when the user touches a point on the screen, the sprite should move to that point. This is working mostly fine... it's even taking into account a delta - because frame rate may not be consistant. However, I notice that the y movement usually finishes before the x movement (even when the distances to travel are the same), so it appears like the sprite is moving in an 'L' shape rather than a smooth diagonal line. Vertical and horizontal velocity (vx, vy) are both set to 300. Any ideas what's wrong? How can I go about getting my sprite to move in a smooth diagonal line? - (void)update:(ccTime)dt { int x = self.position.x; int y = self.position.y; //if ball is to the left of target point if (x<targetx) { //if movement of the ball won't take it to it's target position if (x+(vx *dt) < targetx) { x += vx * dt; } else { x = targetx; } } else if (x>targetx) //same with x being too far to the right { if (x-(vx *dt) > targetx) { x -= vx * dt; } else { x = targetx; } } if (y<targety) { if (y+(vy*dt)<targety) { y += vy * dt; } else { y = targety; } } else if (y>targety) { if (y-(vy*dt)>targety) { y -= vy * dt; } else { y = targety; } } self.position = ccp(x,y); }

• Confused about definition of a 'median' when constructing a kd-Tree

  - by user352636

  Hi there. Im trying to build a kd-tree for searching through a set of points, but am getting confused about the use of 'median' in the wikipedia article. For ease of use, the wikipedia article states the pseudo-code of kd-tree construction as: function kdtree (list of points pointList, int depth) { if pointList is empty return nil; else { // Select axis based on depth so that axis cycles through all valid values var int axis := depth mod k; // Sort point list and choose median as pivot element select median by axis from pointList; // Create node and construct subtrees var tree_node node; node.location := median; node.leftChild := kdtree(points in pointList before median, depth+1); node.rightChild := kdtree(points in pointList after median, depth+1); return node; } } I'm getting confused about the "select median..." line, simply because I'm not quite sure what is the 'right' way to apply a median here. As far as I know, the median of an odd-sized (sorted) list of numbers is the middle element (aka, for a list of 5 things, element number 3, or index 2 in a standard zero-based array), and the median of an even-sized array is the sum of the two 'middle' elements divided by two (aka, for a list of 6 things, the median is the sum of elements 3 and 4 - or 2 and 3, if zero-indexed - divided by 2.). However, surely that definition does not work here as we are working with a distinct set of points? How then does one choose the correct median for an even-sized list of numbers, especially for a length 2 list? I appreciate any and all help, thanks! -Stephen

• Really simple JSON serialization in .NET

  - by Evgeny

  I have some simple .NET objects I'd like to serialize to JSON and back again. The set of objects to be serialized is quite small and I control the implementation, so I don't need a generic solution that will work for everything. Since my assembly will be distributed as a library I'd really like to avoid a dependency on some third-party DLL: I just want to give users one assembly that they can reference. I've read the other questions I could find on converting to and from JSON in .NET. The recommended solution of JSON.NET does work, of course, but it requires distributing an extra DLL. I don't need any of the fancy features of JSON.NET. I just need to handle a simple object (or even dictionary) that contains strings, integers, DateTimes and arrays of strings and bytes. On deserializing I'm happy to get back a dictionary - it doesn't need to create the object again. Is there some really simple code out there that I could compile into my assembly to do this simple job? I've also tried System.Web.Script.Serialization.JavaScriptSerializer, but where it falls down is the byte array: I want to base64-encode it and even registering a converter doesn't let me easily accomplish that due to the way that API works (it doesn't pass in the name of the field).

• Why is this CHOICE element not getting assigned in my SharePoint Field definition schema?

  - by ccornet

  I defined a new field of the type "Choice" for my web application. It will serve basically as a pseudo-lookup as its contents are defined by the value of a Text field in a list. It is initialized with a dummy choice to begin with (I'm under the impression a choice field needs at least one choice when defined), which is replaced with a real choice later on. But for some reason, this dummy choice is never actually added to the choices! Below is the XML Schema for the field in question. <Field ID="{ALICEH-ASFA-KEGU-IDLISTED}" Name="ddlSystems" Group="Lookup Columns" DisplayName="ddlSystems" Type="Choice" Sealed="FALSE" ReadOnly="FALSE" Hidden="FALSE" FillInChoice="TRUE" DisplaceOnUpgrade="TRUE"> <CHOICES> <CHOICE>BLANULL</CHOICE> </CHOICES> <Default>BLANULL</Default> </Field> Initially, I used a default choice of (a single space), but I changed it to BLANULL so that I can parse an actual word instead of a veritably empty string. Now, even after having uninstalled and reinstalled the feature with this field, I have a choice field that has (still a single space) as the only choice. Even more perplexing, BLANULL is actually listed for the default value in both the UI and the object model! What is causing this problem, and how can I circumvent it so that I don't have to manually set this dummy value each time?

• How to use VC++ intrinsic functions w/o run-time library

  - by Adrian McCarthy

  I'm involved in one of those challenges where you try to produce the smallest possible binary, so I'm building my program without the C or C++ run-time libraries (RTL). I don't link to the DLL version or the static version. I don't even #include the header files. I have this working fine. For some code constructs, the compiler generates calls to memset(). For example: struct MyStruct { int foo; int bar; }; MyStruct blah = {}; // calls memset() Since I don't include the RTL, this results in a missing symbol at link time. I've been getting around this by avoiding those constructs. For the given example, I'll explicitly initialize the struct. MyStruct blah; blah.foo = 0; blah.bar = 0; But memset() can be useful, so I tried adding my own implementation. It works fine in Debug builds, even for those places where the compiler generates an implicit call to memset(). But in Release builds, I get an error saying that I cannot define an intrinsic function. You see, in Release builds, intrinsic functions are enabled, and memset() is an intrinsic. I would love to use the intrinsic for memset() in my release builds, since it's probably inlined and smaller and faster than my implementation. But I seem to be a in catch-22. If I don't define memset(), the linker complains that it's undefined. If I do define it, the compiler complains that I cannot define an intrinsic function. I've tried adding #pragma intrinsic(memset) with and without declarations of memset, but no luck. Does anyone know the right combination of definition, declaration, #pragma, and compiler and linker flags to get an intrinsic function without pulling in RTL overhead?

• Ajax UpdatePanels scroll on partial page update.

  - by George

  I set the AutoPostback property of a textbox to True so I can process the TextChanged event on the server and, based on what they typed in the textbox, appropriately display a message in an update panel. The problem is, when the partial screen refresh is performed, no control on the screen has focus. 99% of the time, when the text in the textbox is changed, it is because the user has tabbed forward, and so, to limit the disruption in the lost of focus, I perform a "Focus" call on teh next control in the tab sequence. For the most part, this works OK, but of course, is disputive if the user is tabbing in the reverse order or has used the mouse to set the focus to another control. In these situations, the focus would be set to the next control even though the user was trying to set focus elsewhere. OK, that sucks. Now what I consider the bigger problem with calling the focus method on the server: In IE, it works OK, but in Mozilla Firefox and Chrome, setting the focus causes a repositioning of the scroll bar, even though none is necessary because the control is already in view. I realize that I could switch to doing AJAX web service calls, but these darn Updae Panels are so convenient if used in moderation. is there anyway to use updatepanels and not have these focus/scroll issues?

• Search book by title, and author

  - by Swoosh

  I got a table with columns: author firstname, author lastname, and booktitle Multiple users are inserting in the database, through an import, and I'd like to avoid duplicates. So I'm trying to do something like this: I have a record in the db: First Name: "Isaac" Last Name: "Assimov" Title: "I, Robot" If the user tries to add it again, it would be basically a non-split-text (would not be split up into author firstname, author lastname, and booktitle) So it would basically look like this: "Isaac Asimov - I Robot" or "Asimov, Isaac - I Robot" or "I Robot by Isaac Asimov" You see where I am getting at? (I cannot force the user to split up all the books into into author firstname, author lastname, and booktitle, and I don't even like the idea to force the user, because it's not too user-friendly) What is the best way (in SQL) to compare all this possible bookdata scenarios to what I have in the database, not to add the same book twice. I was thinking about a possibility of suggesting the user: "is THIS the book you are trying to add?" (imagine a list instead of the THIS word, just like on stackoverflow - ask question - Related Questions. I was thinking about soundex and maybe even the like operators, but so far i didn't get the results i was hoping.

• WPF - Why doesn't Microsoft supply a decent set of most-used controls ?

  - by IUsedToBeAPygmy

  I've been playing with WPF for some months now, and I quite like it. But one of the things I don't get is why MS doesn't put a little more effort in helping developers by supplying basic controls, and I need to get this off my chest :) For example, I figure most applications somewhere will need to let you edit some properties - for configuration or whatever. What would be the most used types in a proprety-grid editor ? text numbers (byte, float/double, int, etc) colors ....etc. So why isn't there even something as simple as a control to edit numbers ? Like a generic NumericUpDown control that allows you to type in numbers (no text, no pasting invalid input) or spin them up/down according to some given rules (decimal, floating point, min/maxvalue) ? Why isn't there a generic colorpicker, so people get the same user-experience in every application ? Why isn't there a standard implementation of a SearchTextBox, a BreadCrumb-control, or all these other standard control types users have gotten accustomed to the last 10 years ? (..but at least they DID have the time to implement a generic splashscreen - because everyone knows that greatly increases user-productivity....) The well-known ideal is always to give people the same user-experience over different applications. So even if some of those controls would be easy to make - it would be preferred to have one version over different applications. I see people all over the internet trying to do the same stuff over and over again. Okay, so MS started a WPF Toolkit project on Codeplex that tries to implement some controls, but only did so half-heartedly and is completely dead by now (last update of the roadmap dates back to Mar 21 2009). The result of this is that a lot of people starting a WPF-project end up spending a lot of time on trying to figure out how to create some generic controls and get really frustrated. Wasn't the mantra "Developers, developers, developers!" ..? /Rant

• firefox and javascript redirection

  - by Joe

  Hello there, I currently have a issue with firefox, where all other browser behave in the right way - even IE6! What I want to do is redirection to a subpage but leaving a history entry. There are 2 methods of rewriting the url as far as I know: window.location = "some.url"; - redirect to some.url with history entry window.location.replace("some.url"); - redirect without history entry So I have to use the first one and tested in the firebug console everthing works fine. Now there is the kind of strange part of this question: the same statement, that worked fine in the console doesn't in some jQuery callback handler: jQuery("#selector").bind("submit", function() { $.getJSON("some_cool_json", function(response) { var redirect_path = response.path; window.location = redirect_path; }); return false; }); where response_path is set correctly, I checked it! Even the redirection is working correctly, but there is no history entry created. Any ideas on that one? Would be great! ;) Cheers Joe

• vs10 not deploying all required files - then not over-writing updated files

  - by justSteve

  I'm in the habit of deploying to alternating folders (/inetpub/wwwroot/mySite & /inetpub/wwwroot/mySite2) so if something unexpected happens with the deploy i can quickly swap back to a previous version just by changing the path in IIS So i was deploying an MVC2 webapp to a empty folder figuring that VS would send up all the files it needs. Not even close. Initially, it didn't even upload a couple required nHibernate.dlls. Later, after manually copying files referenced in the thrown exceptions, i just copied all the files from the previous compile and then re-published over the top expecting VS to over-write the changed files. Failed that too. No reports of errors by VS....just failed to over-write a number of pre-existing (but changed/updated) files. Hard to believe these kinds of errors (and lack of feedback that errors were encountered) in a state of the art tool like VS. Clearly, I'm doing something wrong. I'm using VisualSVN for source control and connect to my colocated server via a VPN-based mapped network drive (so I can use FileSystem to publish). (both of which can complicate file properties) VS08 had more choices for which files it would send up - i found i needed to use the 'All files in source' on an initial deployment, the 'Replace Matching'. If I choose 'delete all existing...' I'd be back to square 1 and have to deploy with the 'All files in source project folder'. But VS10 doesn't have the 'All files in source project folder. I ended up manually copying the files - which seems not right in the extreme. Are these known issues others have to deal with? What's best practice for deploying a web-app? thx

• Unable to access Java-created file -- sometimes

  - by BlairHippo

  In Java, I'm working with code running under WinXP that creates a file like this: public synchronized void store(Properties props, byte[] data) { try { File file = filenameBasedOnProperties(props); if ( file.exists() ) { return; } File temp = File.createTempFile("tempfile", null); FileOutputStream out = new FileOutputStream(temp); out.write(data); out.flush(); out.close(); file.getParentFile().mkdirs(); temp.renameTo(file); } catch (IOException ex) { // Complain and whine and stuff } } Sometimes, when a file is created this way, it's just about totally inaccessible from outside the code (though the code responsible for opening and reading the file has no problem), even when the application isn't running. When accessed via Windows Explorer, I can't move, rename, delete, or even open the file. Under Cygwin, I get the following when I ls -l the directory: ls: cannot access [big-honkin-filename] total 0 ?????????? ? ? ? ? ? [big-honkin-filename] As implied, the filenames are big, but under the 260-character max for XP (though they are slightly over 200 characters). To further add to the sense the my computer just wants me to feel stupid, sometimes the files created by this code are perfectly normal. The only pattern I've spotted is that once one file in the directory "locks", the rest are screwed. Anybody ever run into something like this before, or have any insights into what's going on here?

• eclipse django using wrong settings.py in pythonpath

  - by user1290264

  I have pydev/django installed in eclipse, and it runs fine. However, after adding a second django project to eclipse and running the server ('http://127.0.0.1:8000') the pythonpath seems to be stuck on project2 even when I run project1. As a summary, I have two django projects: project1, project2. When I run the django server for project1 I get: Validating models... 0 errors found Django version 1.5, using settings 'project1.settings' Development server is running at 'http://127.0.0.1:8000/' Quit the server with CTRL-BREAK. The above seems to suggest that django is using the correct settings file; however, when I go to 'http://127.0.0.1:8000/' it displays the urls from project2. Also, if I go to 'http://127.0.0.1:8000/admin' the models are getting pulled from the sqlite.db file in project2 as well. I've even tried removing project2 from eclipse entirely and now at 'http://127.0.0.1:8000/admin' I get this error: Python Path: ['C:\Users\Brad\workspaces\In Progress\project2', 'C:\Users\Brad\workspaces\In Progress\project2', 'C:\Python27\DLLs', 'C:\Python27\lib', 'C:\Python27\lib\plat-win', 'C:\Python27\lib\lib-tk', 'C:\Python27', 'C:\Python27\lib\site-packages', 'C:\Windows\system32\python27.zip'] If I run the server on a different port with project1 the path seems to be fine: runserver 7000 --noreload Then 'http://127.0.0.1:7000/' uses project1's paths, but it doesn't seem like I should have to do this. Note: I have setup the run configurations as correctly as I know how. In the main tab, the project and main module both point to the correct project (project1), and the "PYTHONPATH that will be used in the run:" includes project1. Also, I have cleared my browser history, cookies, and everything that chrome would let me delete.

I changes the rules as follow: (Even though i donot want to Use Listing and Detail in start of url Why as i see on some site as i want:: dubai.dubizzle.com/classified/autos4x4s/mitsubishi/lancer/2011/3/12/l ancer-2002-in-good-condition-14/) Listing pages RewriteRule ^Listing/(.)/(.)/(.)/(.)/?$ ads.php?c1=$1&c2=$2&c3=$3&c4=$4 [NC,L] Detail pages RewriteRule ^Detail/(.)/(.)/(.)/(.)/(.)/(.)/?$ detail.php?c1=$1&c2=$2&c3=$3&c4=$4&dt=$5&at=$6 [NC,L] Now all other pages are fine, but when i pass www.example.com/classified/autos4x4s/mitsubishi/lancer/2011/3/12/lanc er-2002-in-good-condition-14/ it always goes to Listing page (ads.php) not to detail page. Any help would be appreciated.

• C#: Is it possible to use expressions or functions as keys in a dictionary?

  - by Svish

  Would it work to use Expression<Func<T>> or Func<T> as keys in a dictionary? For example to cache the result of heavy calculations. For example, changing my very basic cache from a different question of mine a bit: public static class Cache<T> { // Alternatively using Expression<Func<T>> instead private static Dictionary<Func<T>, T> cache; static Cache() { cache = new Dictionary<Func<T>, T>(); } public static T GetResult(Func<T> f) { if (cache.ContainsKey(f)) return cache[f]; return cache[f] = f(); } } Would this even work? Edit: After a quick test, it seems like it actually works. But I discovered that it could probably be more generic, since it would now be one cache per return type... not sure how to change it so that wouldn't happen though... hmm Edit 2: Noo, wait... it actually doesn't. Well, for regular methods it does. But not for lambdas. They get various random method names even if they look the same. Oh well c",)

• C# reference collection for storing reference types

  - by ivo s

  I like to implement a collection (something like List<T>) which would hold all my objects that I have created in the entire life span of my application as if its an array of pointers in C++. The idea is that when my process starts I can use a central factory to create all objects and then periodically validate/invalidate their state. Basically I want to make sure that my process only deals with valid instances and I don't re-fetch information I already fetched from the database. So all my objects will basically be in one place - my collection. A cool thing I can do with this is avoid database calls to get data from the database if I already got it (even if I updated it after retrieval its still up-to-date if of course some other process didn't update it but that a different concern). I don't want to be calling new Customer("James Thomas"); again if I initted James Thomas already sometime in the past. Currently I will end up with multiple copies of the same object across the appdomain - some out of sync other in sync and even though I deal with this using timestamp field on the MSSQL server I'd like to keep only one copy per customer in my appdomain (if possible process would be better). I can't use regular collections like List or ArrayList for example because I cannot pass parameters by their real local reference to the their existing Add() methods where I'm creating them using ref so that's not to good I think. So how can this be implemented/can it be implemented at all ? A 'linked list' type of class with all methods working with ref & out params is what I'm thinking now but it may get ugly pretty quickly. Is there another way to implement such collection like RefList<T>.Add(ref T obj)? So bottom line is: I don't want re-create an object if I've already created it before during the entire application life unless I decide to re-create it explicitly (maybe its out-of-date or something so I have to fetch it again from the db). Is there alternatives maybe ?

• CheckBox won't toggle in Android ListView with focusable="false"

  - by user3563124

  I'm creating a ListView with a custom Adapter for displaying my entries. Each row contains a checkbox, and my adapter contains the following code: CheckBox cb = (CheckBox) v.findViewById(R.id.item_sold); cb.setChecked(p.isSold); setupCheckboxListener(cb, v, position); ... private void setupCheckboxListener(CheckBox check, final View v, final int position) { check.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { CheckBox cb = (CheckBox) v; if (cb.isChecked()) { System.out.println("Should become false!"); cb.setChecked(false); } else { System.out.println("Should become true!"); cb.setChecked(true); } } }); My row XML file includes the following: <CheckBox android:id="@+id/item_sold" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="0.10" android:layout_gravity="center" android:gravity="center" android:focusable="false" android:clickable="false"/> But anytime I press one of the checkboxes, check.isChecked() returns true, even if the box is unchecked. I even checked to make sure that the checkboxes were distinct and weren't picking up just the last value/etc. Setting up the listeners inline instead of in a method doesn't seem to help, either. It's literally just the isChecked() condition that isn't working appropriately - it seems to always give me the inverse value. Setting an onClick on the row is not acceptable in this case because I need to allow row selection for something else. What could be causing this issue?

• ASP.NET Memory Usage in IIS is FAR greater than in DevEnv. Is this normal?

  - by Tom

  Greetings! I have an ASP.NET app that scrapes data from a handful of external pages, parses the relevant bits and displays them in a table. Total data retrieved is 3-4MB and the resulting page is about 1MB. I am using synchronous WebRequest GetResponse for the retrieval, but the same problem existed using an asynchronous BeginGetResponse/EndGetResponse process. There is no database access, no session storage, no caching, but an in-memory list of about 100 objects (total 1MB of data), plus a good amount of AJAX (AjaxControlToolkit). This issue appears on the very first run of the app, even if I have restarted IIS. The issue: When I run the app on my dev computer, the maximum commit charge is about 1.5GB. The biggest user, measured by Task Manager's VM Size, is WebDev.WebServer.exe (600MB). The app runs perfectly. When I run it on my rent-a-server (IIS 7.5, 1GB RAM), the maximum commit charge is over 3.8GB. The biggest user is w3wp.exe at 2.7GB. IIS grinds to a halt and spits out a timed-out error page. Given my limited server budget and the hope of having multiple simultaneous users, I'm kind of in a panic. Is this normal? If I bump the server RAM up to 4GB, will that be enough? Will multiple users require even more memory? Could the culprit be AJAX or the list of objects? Thanks for any insight you can provide.
