  • Invalid controller using custom routes

    - by AlexW
    I've been following the instruction on how to create custom routes from the book Zend Framework - A Beginners Guide I've changed my application.ini file to include this routing information: resources.router.routes.static-content.route = /content/:page resources.router.routes.static-content.defaults.module = default resources.router.routes.static-content.defaults.controller = static-content resources.router.routes.static-content.defaults.view = static-content resources.router.routes.static-content.defaults.action = display Given the above configuration, I have this controller: <?php class Default_StaticContentController extends Zend_Controller_Action { public function init() { /* Initialize action controller here */ } public function displayAction() { // action body $page = $this->getRequest()->getParam('page'); if (file_exists($this->view->getScriptPath(null) . '/' . $this->getRequest()->getControllerName() . '/' . $page . $this->viewSuffix )) { $this->render($page); } else { throw new Zend_Controller_Action_Exception('HLC - Page not found', 404); } } } I have a view named about.phtml in the APPLICATION_PATH/modules/default/views/static-content folder. What ahppens is I get an error saying: An error occurred Page not found Exception information: Message: Invalid controller class ("StaticContentController") Stack trace: #0 /Applications/MAMP/htdocs/zend/library/Zend/Controller/Dispatcher/Standard.php(262): Zend_Controller_Dispatcher_Standard->loadClass('StaticContentCo...') #1 /Applications/MAMP/htdocs/zend/library/Zend/Controller/Front.php(954): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #2 /Applications/MAMP/htdocs/zend/library/Zend/Application/Bootstrap/Bootstrap.php(97): Zend_Controller_Front->dispatch() #3 /Applications/MAMP/htdocs/zend/library/Zend/Application.php(366): Zend_Application_Bootstrap_Bootstrap->run() #4 /Applications/MAMP/htdocs/HLC/public/index.php(26): Zend_Application->run() #5 {main} Request Parameters: array ( 'page' => 'about', 'module' => 'default', 'controller' => 'static-content', 'view' => 'static-content', 'action' => 'display', ) Note that it is not rendering my customised Zend_Controller_Action_Exception but throwing the global error. I'm using the URL: http://hlc.local:8888/content/about The default index action works ok, just this routing that's not working.

  • Silverlight performance with many loaded controls

    - by gius
    I have a SL application with many DataGrids (from Silverlight Toolkit), each on its own view. If several DataGrids are opened, changing between views (TabItems, for example) takes a long time (few seconds) and it freezes the whole application (UI thread). The more DataGrids are loaded, the longer the change takes. These DataGrids that slow the UI chanage might be on other places in the app and not even visible at that moment. But once they are opened (and loaded with data), they slow showing other DataGrids. Note that DataGrids are NOT disposed and then recreated again, they still remain in memory, only their parent control is being hidden and visible again. I have profiled the application. It shows that agcore.dll's SetValue function is the bottleneck. Unfortunately, debug symbols are not available for this Silverlight native library responsible for drawing. The problem is not in the DataGrid control - I tried to replace it with XCeed's grid and the performance when changing views is even worse. Do you have any idea how to solve this problem? Why more opened controls slow down other controls? I have created a sample that shows this issue: http://cenud.cz/PerfTest.zip UPDATE: Using VS11 profiler on the sample provided suggests that the problem could be in MeasureOverride being called many times (for each DataGridCell, I guess). But still, why is it slower as more controls are loaded elsewhere? Is there a way to improve the performance?

  • What is the benefit of using ONLY OpenID authentication on a site?

    - by Peter
    From my experience with OpenID, I see a number of significant downsides: Adds a Single Point of Failure to the site It is not a failure that can be fixed by the site even if detected. If the OpenID provider is down for three days, what recourse does the site have to allow its users to login and access the information they own? Takes a user to another sites content and every time they logon to your site Even if the OpenID provider does not have an error, the user is re-directed to their site to login. The login page has content and links. So there is a chance a user will actually be drawn away from the site to go down the Internet rabbit hole. Why would I want to send my users to another company's website? [ Note: my provider no longer does this and seems to have fixed this problem (for now).] Adds a non-trivial amount of time to the signup To sign up with the site a new user is forced to read a new standard, chose a provider, and signup. Standards are something that the technical people should agree to in order to make a user experience frictionless. They are not something that should be thrust on the users. It is a Phisher's Dream OpenID is incredibly insecure and stealing the person's ID as they log in is trivially easy. [ taken from David Arno's Answer below ] For all of the downside, the one upside is to allow users to have fewer logins on the Internet. If a site has opt-in for OpenID then users who want that feature can use it. What I would like to understand is: What benefit does a site get for making OpenID mandatory?

  • about c# OBJECTS and the Possibilties it has.

    - by user527825
    As a novice programmer and i always wonder about c# capabilities.i know it is still early to judge that but all i want to know is can c# do complex stuffs or something outside windows OS. 1- I think c# is a proprietary language (i don't know if i said that right) meaning you can't do it outside visual studio or windows. 2-also you cant create your own controller(called object right?) like you are forced to use these available in toolbox and their properties and methods. 3-can c# be used with openGL API or DirectX API . 4-Finally it always bothers me when i think i start doing things in visual studio, i know it sounds arrogant to say but sometimes i feel that i don't like to be forced to use something even if its helpful, like i feel (do i have the right to feel?) that i want to do all things by myself? don't laugh i just feel that this will give me a better understanding. 5- is visual c# is like using MaxScript inside 3ds max in that c# is exclusive to do windows and forms and components that are windows related and maxscript is only for 3d editing and manipulation for various things in the software. If it is too difficult for a beginner i hope you don't answer the fourth question as i don't have enough motivation and i want to keep the little i have. thank you for your time. Note: 1-sorry for my English, i am self taught and never used the language with native speakers so expect so errors. 2-i have a lot of questions regarding many things, what is the daily ratio you think for asking (number of questions) that would not bother the admins of the site and the members here. thank you for your time.

  • Can this auto-stretcing scenario be realized undex XHTML/CSS?

    - by Vilx-
    I want two horizontal areas in my webpage. The first one is the menu. It's on the top. Unfortunately I don't know its size, and it might change in response to user actions. Below the menu is the main area which should stretch at least as far as the bottom of the window (if there is little content) or beyond (if there is a lot of content. To illustrate with ASCII art: +----------------------------------------------------+ | This area resizes vertically depending on contents | +----------------------------------------------------+ | This area stretches to the bottom of the window, | | but can be even larger if necessary. Note: this | | should be a separate area because it will contain | | children with height:100% as well. | | | +----------------------------------------------------+ Can this be done? Can it be done with Javascript? Added: To put things in perspective and avoid confusion, think of it this way: the top menu is generated by myself, but the bottom area is an IFrame which I want to fill the rest of the page. This is what it eventually comes down to anyway in my case.

  • Lazy loading is not working for one to many

    - by Shire
    Any 1-M that use the primary key of the parent table, but any 1-M that uses a different column does not work. It generates the SQL correctly, but put the value of the key into the SQL instead of the column value I want. Example mapping: public TemplateMap() { Table("IMPORT"); LazyLoad(); Id(x => x.ImportId).Column("IMPORT_ID").GeneratedBy.Assigned(); Map(x => x.ImportSetId).Column("IMPORTSET_ID"); HasMany(x => x.GoodChildren) .Access.CamelCaseField() .KeyColumns.Add("IMPORT_ID") .Cascade.Delete() .Inverse(); HasMany(x => x.BadChildren) .Access.CamelCaseField() .KeyColumns.Add("IMPORTSET_ID") .Cascade.Delete() .Inverse(); } Lazy loading works for GoodChildren, but not for BadChildren. The SQL statement is correct for both children. But the wrong values are use. If the value of IMPORT_ID is 10 and the value of IMPORTSET_ID is 12. The value 10 will be used for the IMPORTSET_ID in the SQL for BadChildren instead of 12. Anyone have any ideas what I need to change to get BadChildren to work correctly? Note: GoodChildren links to IMPORT_ID on Template BadChildren links to IMPORTSET_ID on Template

  • Packet fragmentation when sending data via SSLStream

    - by Ive
    When using an SSLStream to send a 'large' chunk of data (1 meg) to a (already authenticated) client, the packet fragmentation / dissasembly I'm seeing is FAR greater than when using a normal NetworkStream. Using an async read on the client (i.e. BeginRead()), the ReadCallback is repeatedly called with exactly the same size chunk of data up until the final packet (the remainder of the data). With the data I'm sending (it's a zip file), the segments happen to be 16363 bytes long. Note: My receive buffer is much bigger than this and changing it's size has no effect I understand that SSL encrypts data in chunks no bigger than 18Kb, but since SSL sits on top of TCP, I wouldn't think that the number of SSL chunks would have any relevance to the TCP packet fragmentation? Essentially, the data is taking about 20 times longer to be fully read by the client than with a standard NetworkStream (both on localhost!) What am I missing? EDIT: I'm beginning to suspect that the receive (or send) buffer size of an SSLStream is limited. Even if I use synchronous reads (i.e. SSLStream.Read()), no more data ever becomes available, regardless of how long I wait before attempting to read. This would be the same behavior as if I were to limit the receive buffer to 16363 bytes. Setting the Underlying NetworkStream's SendBufferSize (on the server), and ReceiveBufferSize (on the client) has no effect.

  • Regular Expression to replace a pattern at runtime(C#3.0)

    - by deepak.kumar.goyal
    I have a requirement. I have some files in a folder among which some file names looks like say **EUDataFiles20100503.txt, MigrateFiles20101006.txt.** Basically these are the files that I need to work upon. Now I have a config file where it is mentioned as the file pattern type as EUDataFilesYYYYMMDD, MigrateFilesYYYYMMDD. Basically the idea is that, the user can configure the file pattern and based on the pattern mentioned, I need to search for those files that are present in the folder. i.e. at runtime the YYYYMMDD will get replaced by the Year Month and Date Values. It does not matter what dates will be there(but not with time stamp ; only dates)). And the EUDataFiles or MigrateFiles names will be there.(they are fixed) i.e. If the folder has a file name as EUDataFile20100504.txt(i.e. Year 2010, Month 05, Day 04) , I should ignore this file as it is not EUDataFiles20100504.txt (kindly note that the name is plural - File(s) and not file for which the system will ignore the file). Similarly, if the Pattern given as EUDataFilesYYYYMMDD and if the file present is of type EUDataFilesYYYYDDMM then also the system should ignore. How can I solve this problem? Is it doable using regular expression(Replacing the pattern at runtime)? If so can anyone be good enough in helping me out? I am using C#3.0 and dotnet framework 3.5. Thanks

  • Stopping/Removing an embedded player.

    - by Rajat
    Hi, I am working on a webpage where i have to include an embedded video.The video is hosted on some other domain.I am able to embed the video and autoplay once the web page is loaded.However i have a requirement where i have to remove the div displaying the video once it is played , and in place of the video i have to now display some text. The problem is i am able to do autoplay by the autostart variable in the embed tag...but how do i know that the video has ended.The hosting company only provides an embed tag and they donot have any player apis to use. One way (or rather a workaround) that i feel is to start a eventlistener in the background and see for the total time of the video and when that time is reached remove the content.But the problem is what if the user pauses the video, then also the div would be deleted. I am new to flash.Are there some standard variables or actions that we can pass as flashvars to a swf file to stop a running player or to know the state of the player (Note we are only getting an embed tag from the video hosting site so we donot own that code and they donot have much documenation to help me out with the code). Thanks for your help.

  • SQL Server INSERT, Scope_Identity() and physical writing to disc

    - by TheBlueSky
    Hello everyone, I have a stored procedure that does, among other stuff, some inserts in different table inside a loop. See the example below for clearer understanding: INSERT INTO T1 VALUES ('something') SET @MyID = Scope_Identity() ... some stuff go here INSERT INTO T2 VALUES (@MyID, 'something else') ... The rest of the procedure These two tables (T1 and T2) have an IDENTITY(1, 1) column in each one of them, let's call them ID1 and ID2; however, after running the procedure in our production database (very busy database) and having more than 6250 records in each table, I have noticed one incident where ID1 does not match ID2! Although normally for each record inserted in T1, there is record inserted in T2 and the identity column in both is incremented consistently. The "wrong" records were something like that: ID1 Col1 ---- --------- 4709 data-4709 4710 data-4710 ID2 ID1 Col1 ---- ---- --------- 4709 4710 data-4709 4710 4709 data-4710 Note the "inverted", ID1 in the second table. Knowing not that much about SQL Server underneath operations, I have put the following "theory", maybe someone can correct me on this. What I think is that because the loop is faster than physically writing to the table, and/or maybe some other thing delayed the writing process, the records were buffered. When it comes the time to write them, they were wrote in no particular order. Is that even possible if no, how to explain the above mentioned scenario? If yes, then I have another question to rise. What if the first insert (from the code above) got delayed? Doesn't that mean I won't get the correct IDENTITY to insert into the second table? If the answer of this is also yes, what can I do to insure the insertion in the two tables will happen in sequence with the correct IDENTITY? I appreciate any comment and information that help me understand this. Thanks in advance.

  • String or binary data would be truncated -- Heisenberg problem

    - by harpo
    When you get this error, the first thing you ask is, which column? Unfortunately, SQL Server is no help here. So you start doing trial and error. Well, right now I have a statement like: INSERT tbl (A, B, C, D, E, F, G) SELECT A, B * 2, C, D, E, q.F, G FROM tbl ,othertable q WHERE etc etc Note that Some values are modified or linked in from another table, but most values are coming from the original table, so they can't really cause truncation going back to the same field (that I know of). Eliminating fields one at a time eventually makes the error go away, if I do it cumulatively, but — and here's the kicker — it doesn't matter which fields I eliminate. It's as if SQL Server is objecting to the total length of the row, which I doubt, since there are only about 40 fields in all, and nothing large. Anyone ever seen this before? Thanks. UPDATE: I have also done "horizontal" testing, by filtering out the SELECT, with much the same result. In other words, if I say WHERE id BETWEEN 1 AND 100: Error WHERE id BETWEEN 1 AND 50: No error WHERE id BETWEEN 50 AND 100: No error I tried many combinations, and it cannot be limited to a single row.

  • Django unit testing: South-migrated DB works in MySQL, throws duplicate PK error in PostGreSQL. Am I

  • Dynamically changing background color of a UIView

    - by EricM
    Hello- Here's my setup. I have a viewcontroller that I'm creating and adding as a subview. The viewcontroller presents some options that a user can chose from. The viewcontroller is being pushed in response to a "long press" gesture. Within the viewcontroller, I added a child UIView to group some other controls together so I can move them around the screen as a unit and, when they are displayed, center them on the location of the long press. Here is the code that instantiates the view controller, changes its location, and adds it as a subview: UserOptions *opts = [[UserOptions alloc] initWithNibName:@"UserOptions" bundle:nil]; [opts recenterOptions:location]; [self.view addSubview:opts.view]; That bit of code does create and push the viewcontroller, but the call to recenterOptions doesn't do anything. Here is that method: - (void) recenterOptions:(CGPoint)location { CGRect oldFrame = self.optionsView.frame; CGFloat newX = location.x; // + oldFrame.size.width / 2.0; CGFloat newY = location.y; // + oldFrame.size.height / 2.0; CGRect newFrame = CGRectMake(newX, newY, oldFrame.size.width, oldFrame.size.height); self.optionsView.frame = newFrame; } Note that self.optionsView is the child UIView that I added to the viewcontroller's nib. Does anyone know why I'm unable to change the location of the UIView? Regards, Eric

    Umm, ok, after sending some data to the server, noting this particular part: "Accept-Encoding: gzip,deflate\r\n" I am getting the following response: HTTP/1.1 200 OK Server: nginx Date: Fri, 09 Apr 2010 23:25:27 GMT Content-Type: text/html; charset=UTF-8 Transfer-Encoding: chunked Connection: keep-alive X-Powered-By: PHP/5.2.8 Expires: Mon, 26 Jul 1997 05:00:00 GMT Last-Modified: Fri, 09 Apr 2010 23:25:27 GMT Cache-Control: no-store, no-cache, must-revalidate Cache-Control: post-check=0, pre-check=0 Pragma: no-cache Content-Encoding: gzip Vary: Accept-Encoding 7aa ??U-?Rh?%?2?w??PM]??7?qZ?K?)???2?&??m???"q??/p9w?????x?[`tA!G???G?5z??????a>k????????Q ???N?? ('??f?,(??Y:5B???-?)?3x^0e:j?`,???**???F>G)?2????@???b??????A?k???Ar?n? But how do I decompress it? Note that I am using the Socket Class to do all the work. I know how to decompress it, but the problem here lies in the fact that I cannot separate the Packet from the GZipped data, psuedo-psuedocode (or whatever) on how I do it: Socket sends packet; Socket reads response from server, stores into a ByteArray; Create MemoryStream, use ByteArray; Create GZipStream, use Memorystream; now the problem occurs; I am getting the following Error: System.IO.InvalidDataException The magic number in GZip header is not correct. Make sure you are passing in a GZip stream. I hope the explanation is clear enough __.

  • c# "==" operator : compiler behaviour with different structs

    - by Moe Sisko
    Code to illustrate : public struct MyStruct { public int SomeNumber; } public string DoSomethingWithMyStruct(MyStruct s) { if (s == null) return "this can't happen"; else return "ok"; } private string DoSomethingWithDateTime(DateTime s) { if (s == null) return "this can't happen"; // XX else return "ok"; } Now, "DoSomethingWithStruct" fails to compile with : "Operator '==' cannot be applied to operands of type 'MyStruct' and '<null>'". This makes sense, since it doesn't make sense to try a reference comparison with a struct, which is a value type. OTOH, "DoSomethingWithDateTime" compiles, but with compiler warning : "Unreachable code detected" at line marked "XX". Now, I'm assuming that there is no compiler error here, because the DateTime struct overloads the "==" operator. But how does the compiler know that the code is unreachable ? e.g. Does it look inside the code which overloads the "==" operator ? (This is using Visual Studio 2005 in case that makes a difference). Note : I'm more curious than anything about the above. I don't usually try to use "==" on structs and nulls.

  • navigate all items in a wpf tree view

    - by Brian Leahy
    I want to be able to traverse the visual ui tree looking for an element with an ID bound to the visual element's Tag property. I'm wondering how i do this. Controls don't have children to traverse. I started using LogicalTreeHelper.GetChildren, which seems to work as intended, up until i hit a TreeView control... then LogicalTreeHelper.GetChildren doesnt return any children. Note: the purpose is to find the visual UI element that corresponds to the data item. That is, given an ID of the item, Go find the UI element displaying it. Edit: I am apparently am not explaining this well enough. I am binding some data objects to a TreeView control and then wanting to select a specific item programaticly given that business object's ID. I dont see why it's so hard to travers the visual tree and find the element i want, as the data object's ID is in the Tag property of the appropriate visual element. I'm using Mole and I am able to find the UI element with the appropriate ID in it's Tag. I just cannot find the visual element in code. LogicalTreeHelper does not traverse any items in the tree. Neither does ItemContainerGenerator.ContainerFromItem retrieve anything for items in the tree view.

  • Concurrent Programming:Should I write a sequential program first, then add thread safety?

    - by evthim
    I'm working on a project where we have to create a number of threads(actual number will be inputted in by testers (TA's)). I'm having trouble not only with the programming but also with the design, I can't wrap my head around all of the threads that will be invoked and where I might cause errors. The project is due soon so I don't want to waste time on this if it'll actually set me back, but I was wondering if I should write the program like only one thread will be running and everything should be sequential and then later go back and try to add the thread safety parts of the code? Would that take twice the original amount of time? Project Description: Note:I'm going to be as vague as possible so I don't violate any honor codes, sorry :( your program should accept n number of objectA threads, m number of objectB threads, and r number of objectC objectB threads interact with code in objectA. objectA threads interact with code in objectB and objectC objectB and objectC don't directly interact, but do so indirectly through objectA -ex: objectB needs something from objectA. objectA gets the result for that something by calling objectC my confusion stems mostly from the fact that all of this interactions will be done by m+n threads and there are various restrictions throughout the descriptions, like objectB can request something from objectA, and objectA has to wait for objectC to finish that something before returning it to objectB. Also each objectA thread can only work on one instruction from objectB at a time, etc. etc. I just want to know if I write the code so that there is only 1 objectA, 1 objectB and 1 object C, can I go back and easily modify it so that those 1's can be changed to m, n and r? Sorry again, if my description is a little bit confusing.

  • array_map applied on a function with 2 parameters

    - by mat
    I've 2 arrays ($numbers and $letters) and I want to create a new array based on a function that combines every $numbers with every $letters. The parameters of this function involes the value of both $numbers and $letters. (Note: $numbers and $letters doesn't have the same amount of values). I need something like this: $numbers = array(1,2,3,4,5,6,...); $letters = array('a','b','c','d','e',...); function myFunction($x,$y){ // $output = some code that use $x and $y return $output; }; $array_1 = array( (myFunction($numbers[0],$letters[0])), (myFunction($numbers[0],$letters[1])), myFunction($numbers[0],$letters[2]), myFunction($numbers[0],$letters[3]), etc); $array_2 = array( (myFunction($numbers[1],$letters[0])), (myFunction($numbers[1],$letters[1])), myFunction($numbers[1],$letters[2]), myFunction($numbers[1],$letters[3]), etc); $array_3 = array( (myFunction($numbers[2],$letters[0])), (myFunction($numbers[2],$letters[1])), myFunction($numbers[2],$letters[2]), myFunction($numbers[2],$letters[3]), etc); ... $array_N = array( (myFunction($numbers[N],$letters[0])), (myFunction($numbers[N],$letters[1])), myFunction($numbers[N],$letters[2]), myFunction($numbers[N],$letters[3]), etc); $array = array($array_1, $array_2, $array_3, etc.); I know that this may work, but it's a lot of code, especially if I have a many values for each array. Is there a way to get the same result with less code? I tried this, but it's not working: $array = array_map("myFunction($value, $letters)",$numbers)); Any help would be appriciated!

  • How to extract ALL typedefs and structs and unions from c++ source

    - by Michael Wells
    I have inherited a Visual Studio project that contains hundreds of files. I would like to extract all the typedefs, structs and unions from each .h/.cpp file and put the results in a file). Each typdef/struct/union should be on one line in the results file. This would make sorting much easier. typdef int myType; struct myFirstStruct { char a; int b;...}; union Part_Number_Serial_Number_Part_2_Response_Message_Type {struct{Message_Response_Head_Type Head; Part_Num_Serial_Num_Part_2_Report_Array Part_2_Report; Message_Tail_Type Tail;} Data; BYTE byData[140];}myUnion; struct { bool c; int d;...}mySecondStruct; My problem is, I do not know what to look for (grammar of typedef/structs/unions) using a regular expression. I cannot believe that nobody has done this before (I googled and have not found anything on this). Does anyone know the regular expressions for these? (Note some are commented out using // others /* */) Or a tool to accomplish this. Edit: I am toying with the idea of autogenerating source code and/or dialogs for modifying messages that use the underlying typedef/struct/union. I was going to use the output to generate an XML file that could be used for this reason. The source for these are in C/C++ and used in almost all my projects. These projects are usually NOT in C/C++. By using the XML version I would only need to update/add the typedef/struct/union only in one place and all the projects would be able to autogen the source and/or dialogs.

  • Nokogiri changing custom elements

    - by dagda1
    Hi, I have sample html that I have marked up with some special tags that will be used by a different program, an example of the html is below. You should note the <START:organization>..<END> elements. <html> <head/> <body> <ul> <li> <START:organization> Advanced Integrated Pest Management <END> </li> <li> <START:organization> American Bakers Association <END> </li> </ul> </body> </html> I wanted to use nokogiri to preprocess the html to easily remove irrelevant tags like <script>. I created the following extension to the nokogiri document class: module Nokogiri module HTML class Document def prepare_html xpath("//script").remove to_html.remove_new_lines end end end end The problem is that nokogiri is changing the <START:organization> element to <organization>. Is there anyway that I can preserve the htnl to maintain my custom markup tags? Thanks Paul
