  • jQuery AJAX Character Encoding Problem

    - by Salty
    Hi everyone, I'm currently coding a French website. There's a schedule page, where a link on the side can be used to load another day's schedule. http://aquate.us/film/horaire.html (At the moment, only the links for November 13th and November 14th work) Here's the JS I'm using to do this: <script type="text/javascript"> function load(y) { $.get(y,function(d) { $("#replace").html(d); mod(); }); } function mod() { $("#dates a").click(function() { y = $(this).attr("href"); load(y); return false; }); } mod(); </script> The actual AJAX works like a charm. My problem lies with the response to the request. Because it is a French website, there are many accented letters. I'm using the ISO-8859-15 charset for that very reason. However, in the response to my AJAX request, the accents are becoming ?'s because the character encoding seems to be changed back to UTF-8. How do I avoid this? I've already tried adding some PHP at the top of the requested documents to set the character set: <?php header('Content-Type: text/html; charset=ISO-8859-15'); ?> But that doesn't seem to work either. Any thoughts? Also, while any of you are looking here...why does the rightmost column seem to become smaller when a new page is loaded, causing the table to distort and each <li> within the <td> to wrap to the next line? Cheers

  • Trying to parse OpenCV YAML ouput with yaml-cpp

    - by Kenn Sebesta
    I've got a series of OpenCv generated YAML files and would like to parse them with yaml-cpp I'm doing okay on simple stuff, but the matrix representation is proving difficult. # Center of table tableCenter: !!opencv-matrix rows: 1 cols: 2 dt: f data: [ 240, 240] This should map into the vector 240 240 with type float. My code looks like: #include "yaml.h" #include <fstream> #include <string> struct Matrix { int x; }; void operator >> (const YAML::Node& node, Matrix& matrix) { unsigned rows; node["rows"] >> rows; } int main() { std::ifstream fin("monsters.yaml"); YAML::Parser parser(fin); YAML::Node doc; Matrix m; doc["tableCenter"] >> m; return 0; } But I get terminate called after throwing an instance of 'YAML::BadDereference' what(): yaml-cpp: error at line 0, column 0: bad dereference Abort trap I searched around for some documentation for yaml-cpp, but there doesn't seem to be any, aside from a short introductory example on parsing and emitting. Unfortunately, neither of these two help in this particular circumstance. As I understand, the !! indicate that this is a user-defined type, but I don't see with yaml-cpp how to parse that.

  • How can I debug why this click handler never fires?

    - by tixrus
    I am going to be excrutiatingly detailed here. I am using Firefox 3.6.3 on Max OSX with Firebug 1.5.3. I have two versions of a project, one which works and one with a bug. One I downloaded and one I typed by hand. Take a guess which one doesn't work. They should be the same except that mine uses a newer version of jQuery and the files are named differently. jQuery version is not the issue. I made mine use the older jquery and I made the working one use the newer jquery. Either way, mine still broke and the downloaded one still works. I've busted my eyes trying to see how these projects are different. The only thing I don't want to do is copy the working code to the busted code because I need to be able to figure this stuff out when it is my own unique code causing similar issues. There are no errors that I can see in Firebug in my code, in fact, 2/3 of it works just fine. just the second button does nothing. So I wanted to step through. These are always eyeball errors and I really suck at seeing them. I put it on a public server. http://colleenweb.com/jqtests/ex71.html And I want to debug ex71.js If you firebug the working one and set a break point at line 13 in ex71.js the variable json has the expected values when you click on the second button. But If you firebug this one, it never gets there. I've been over the html and all the names of everything seem to match up. I also wonder why the buttons aren't right justified but that's a css thing. Please tell me what I'm missing, and more importantly, what tool/technique I could use to find these types of bugs.

  • No long-running conversations - IllegalArgumentException: Stack must not be null

    - by Markos Fragkakis
    Hi all, I have a very simple application with just 2 pages on WebLogic 10.3.2 (11g), Seam 2.2.0.GA. I have a command button in each, which makes a redirect-after-post to the other. This works well, as I see the URL of the current page I am seeing in the address bar. BUT, even though I have no long-running conversations defined, after a random number of clicks, and - I think - after a random number of seconds (~10s - 60s) I get the lovely exception at the end of this post. Now, if I have understood how temporary conversations work when redirecting this happens: When I first see my application, the url is http://localhost:7001/myapp When I click the button in pageA.xhtml, I end up in "pageB.xhtml?cid=26". This is normal because Seam extends the temporary conversation of the first request to last until the renderResponse phase of the redirect. So, it uses the cid (Conversation Id) of the extended temporary conversation to find any propagated parameters. When I click the button in pageB.xhtml, I end up in pageA.xhtml?cid=26 The same cid was given to the new extended temporary conversation. This is normal because the conversation ended at the end of the previous redirect-after-post, and not the number 26 is free to use as a cid. Is this all correct? If yes, why does this happen: If I re-type the applications home address (showing pageA) and re-click, I end up in pageB.xhtml?cid=29, which is a different number than 26. But 26 has ended after the previous RenderResponse phase, befire I re-types the url. Why is it not used instead of 29? So, to sup up, 2 questions: Why do I get the exception, even though I have not started any long-running conversations? What happens exactly with the cid? On what basis does it change? Cheers,

  • Syntax Error with John Resig's Micro Templating after changing template tags <# {% {{ etc..

    - by optician
    I'm having a bit of trouble with John Resig's Micro templating. Can anyone help me with why it isn't working? This is the template <script type="text/html" id="row_tmpl"> test content {%=id%} {%=name%} </script> And the modified section of the engine str .replace(/[\r\t\n]/g, " ") .split("{%").join("\t") .replace(/((^|%>)[^\t]*)'/g, "$1\r") .replace(/\t=(.*?)%>/g, "',$1,'") .split("\t").join("');") .split("%}").join("p.push('") .split("\r").join("\\'") + "');}return p.join('');"); and the javascript var dataObject = { "id": "27", "name": "some more content" }; var html = tmpl("row_tmpl", dataObject); and the result, as you can see =id and =name seem to be in the wrong place? Apart from changing the template syntax blocks from <% % to {% %} I haven't changed anything. This is from Firefox. Error: syntax error Line: 30, Column: 89 Source Code: var p=[],print=function(){p.push.apply(p,arguments);};with(obj){p.push(' test content ');=idp.push(' ');=namep.push(' ');}return p.join('');

  • UIImagePickerController image editing not working

    - by Greg Reichow
    I am having a problem with implementing UIImagePickerController. When the controller loads, it displays modally, and allows the user to select the image. Good so far. Yet, then when it moves to the editing phase, it often displays somewhat corrupted view (the image cropping box is halfway off the top of the screen) and their is no image. It does not crash, but all UI interaction is blocked. The strange part is that this only happens when I compile with Release settings. Under debug compile settings, the image editing works fine! I have tried checking for memory warnings during this time, but none are showing up. Here is the code calling the image picker controller for reference. When I use the camera (the first method), it always works fine. It is just when selecting images from the Library (called from the second method below) does it fail as described above. And again, only on release build, and with various different types of images. - (IBAction) showCameraController:(id)sender { self.imagePicker =[[UIImagePickerController alloc] init]; self.imagePicker.sourceType=UIImagePickerControllerSourceTypeCamera; self.imagePicker.delegate=self; self.imagePicker.allowsEditing=YES; [self presentModalViewController:self.imagePicker animated:YES]; } - (IBAction) showPictureAlbumController:(id)sender { self.imagePicker =[[UIImagePickerController alloc] init]; self.imagePicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary; self.imagePicker.delegate=self; self.imagePicker.allowsEditing=YES; [self presentModalViewController:self.imagePicker animated:YES]; } The delegate methods are properly implemented, yet, during the problem I am describing, the controller is not yet calling those methods. It is failing when displaying the editing screen before the user is able to select cancel or save. It is just locking up with no crash. Please help!

  • python win32com EXCEL data input error

    - by Rafal
    Welcome, I'm exporting results of my script into Excel spreadsheet. Everything works fine, I put big sets of data into SpreadSheet, but sometimes an error occurs: File "C:\Python26\lib\site-packages\win32com\client\dynamic.py", line 550, in __setattr__ self._oleobj_.Invoke(entry.dispid, 0, invoke_type, 0, value) pywintypes.com_error: (-2147352567, 'Exception.', (0, None, None, None, 0, -2146777998), None)*** I suppose It's not a problem of input data format. I put several different types of data strings, ints, floats, lists and it works fine. When I run the sript for the second time it works fine - no error. What's going on? PS. This is code that generates error, what's strange is that the error doesn't occur always. Say 30% of runs results in an error. : import win32com.client def Generate_Excel_Report(): Excel=win32com.client.Dispatch("Excel.Application") Excel.Workbooks.Add(1) Cells=Excel.ActiveWorkBook.ActiveSheet.Cells for i in range(100): Row=int(35+i) for j in range(10): Cells(int(Row),int(5+j)).Value="string" for i in range(100): Row=int(135+i) for j in range(10): Cells(int(Row),int(5+j)).Value=32.32 #float Generate_Excel_Report() The strangest for me is that when I run the script with the same code, the same input many times, then sometimes an error occurs, sometimes not. Thanks in advance for any help

  • Making pascal's triangle with mpz_t's

    - by SDLFunTimes
    Hey, I'm trying to convert a function I wrote to generate an array of longs that respresents Pascal's triangles into a function that returns an array of mpz_t's. However with the following code: mpz_t* make_triangle(int rows, int* count) { //compute triangle size using 1 + 2 + 3 + ... n = n(n + 1) / 2 *count = (rows * (rows + 1)) / 2; mpz_t* triangle = malloc((*count) * sizeof(mpz_t)); //fill in first two rows mpz_t one; mpz_init(one); mpz_set_si(one, 1); triangle[0] = one; triangle[1] = one; triangle[2] = one; int nums_to_fill = 1; int position = 3; int last_row_pos; int r, i; for(r = 3; r <= rows; r++) { //left most side triangle[position] = one; position++; //inner numbers mpz_t new_num; mpz_init(new_num); last_row_pos = ((r - 1) * (r - 2)) / 2; for(i = 0; i < nums_to_fill; i++) { mpz_add(new_num, triangle[last_row_pos + i], triangle[last_row_pos + i + 1]); triangle[position] = new_num; mpz_clear(new_num); position++; } nums_to_fill++; //right most side triangle[position] = one; position++; } return triangle; } I'm getting errors saying: incompatible types in assignment for all lines where a position in the triangle is being set (i.e.: triangle[position] = one;). Does anyone know what I might be doing wrong?

  • Enum Naming Convention - Plural

    - by o.k.w
    I'm asking this question despite having read similar but not exactly what I want at http://stackoverflow.com/questions/495051/c-naming-convention-for-enum-and-matching-property I found I have a tendency to name enums in plural and then 'use' them as singular, example: public enum EntityTypes { Type1, Type2 } public class SomeClass { /* some codes */ public EntityTypes EntityType {get; set;} } Of course it works and this is my style, but can anyone find potential problem with such convention? I do have an "ugly" naming with the word "Status" though: public enum OrderStatuses { Pending, Fulfilled, Error, Blah, Blah } public class SomeClass { /* some codes */ public OrderStatuses OrderStatus {get; set;} } Additional Info: Maybe my question wasn't clear enough. I often have to think hard when naming the variables of the my defined enum types. I know the best practice, but it doesn't help to ease my job of naming those variables. I can't possibly expose all my enum properties (say "Status") as "MyStatus". My question: Can anyone find potential problem with my convention described above? It is NOT about best practice. Question rephrase: Well, I guess I should ask the question this way: Can someone come out a good generic way of naming the enum type such that when used, the naming of the enum 'instance' will be pretty straightforward?

  • AutoMapper How To Map Object A To Object B Differently Depending On Context

    - by IanT8
    Calling all AutoMapper gurus! I'd like to be able to map object A to object B differently depending on context at runtime. In particular, I'd like to ignore certain properties in one mapping case, and have all properties mapped in another case. What I'm experiencing is that Mapper.CreateMap can be called successfully in the different mapping cases however, once CreateMap is called, the map for a particular pair of types is set and is not subsequently changed by succeeding CreateMap calls which might describe the mapping differently. I found a blog post which advocates Mapper.Reset() to get round the problem, however, the static nature of the Mapper class means that it is only a matter of time before a collision and crash occur. Is there a way to do this? What I think I need is to call Mapper.CreateMap once per appdomain, and later, be able to call Mapper.Map with hints about which properties should be included / excluded. Right now, I'm thinking about changing the source code by writing a non-static mapping class that holds the mapping config instance based. Poor performance, but thread safe. What are my options. What can be done? Automapper seems so promising.

  • SimplePie not parsing flickr feed

    - by mn
    I am trying to use SimplePie to pull a group pool flickr feed: $feed = new SimplePie(); $feed->set_feed_url('http://api.flickr.com/services/feeds/groups_pool.gne?id=25938750@N00&lang=en-us&format=rss_200'); $feed->init(); $feed->handle_content_type(); Then I use typical SimplePie php calls to loop through the feed items. However, nothing is returned. The HTML is there, but the feed elements aren't inserted. When I try to use a flickr feed of tags, like: $feed->set_feed_url('http://api.flickr.com/services/feeds/photos_public.gne?tags=architecture,building&lang=en-us&format=rss_200'); I get back a list of photos from the public photo feed, but the tags aren't taken into account. Any ideas? The only thing I can think of is I need an API key, but there is nothing on the flickr website that indicates a key is needed for feed calls. Plus, I can open both types of feeds in my browser and get the feed I am looking for.

  • CCNet: "Failing Tasks : FilteredSourceControl: CheckForModifications" error

    - by Marc
    I've installed CCNet and now I'm trying to set up a link to our repository. When I visit the CCNet dashboard website the project shows up ok, but when I click the Force button I receive this error in the messages column: Failing Tasks : FilteredSourceControl: CheckForModifications If I log into the server as the account which I've specified CCNet should use to connect to the repository, and do an Update on the project by hand (i.e. using SVN.exe or TortoiseSVN) the update works fine. My sourcecontrol section of the CCNet.config file is below. <sourcecontrol type="filtered"> <sourceControlProvider type="svn" autoGetSource="true"> <executable>E:\SVNServer\bin\svn.exe</executable> <trunkUrl> https://bserver.int:4443/trunk </trunkUrl> <workingDirectory>E:\buildserver</workingDirectory> <username>USER</username> <password>PASSWORD</password> </sourceControlProvider> <inclusionFilters> <pathFilter> <pattern>**/*.*</pattern> </pathFilter> </inclusionFilters> </sourcecontrol> Both the cruisecontrol.net website and google seem utterly devoid of any information on this error, other than that it probably relates to the inclusionfilter section in the block above. Can anyone provide any ideas?

    - by Shailesh Jaiswal
    I have one OPC ( OLE for Process control ) server project which is developed into visual studio 2005. I want to run it in visual studio 2008. The coding for the OPC server project is done in VC++. I want to connect my OPC client to this OPC server. When I was opened the OPC server project which was build into visual studio 2005 into visual studio 2008 first time it was asking for conversion wizard. I gone through that wizard & successfully finished that wizard. But when I build ( by right clicking on the project & choosing build solution ) it is giving lots of error near about 64 errors. Most of the errors are like - fetal error C1083:Can not open type library file:'msxml4.dll':No such file or directory, fetal error LINK1181:can not open input file 'rpcndr.lib' , error C2051:case expression not constant. only these 3 types of errors in am getting. All these 3 errors are repeated in Error list & becoming bunch of 64 errors. Please provide me the solution for the above issue. Can you provide me any suusgestion or link or any way through whcih I can resolve the above issue?

  • Detecting which MCUs to connect on an incoming conference

    - by Fábio Batista
    Hello, SO. I'm working with the OCS UCCAPI, developing a custom OCS client. I'm currently having a hard time detecting what "kind" of Conference my client is being invited to. Using the Office Communicator client, I can start "IM conferences" (by inviting more than 1 person and selecting "start a IM conversation") or "video conferences" (by selecting more than 1 person and selecting "start a video call"). The Office Communicator client, on the invitees' end, starts correctly the appropriate session (just IM, just Video or IM+Video). However, when receiving the conference invite on my custom client, there's no data about the kind of session I'm being invited. I need this information, in order to make a decision whether or not to connect to the AV MCU and capture/show video. I've tried already: When handling _IUccSessionManagerEvents.OnIncomingSession, parse the RemoteSessionDescription property on the UccIncomingInvitationEvent object: no luck, the only data about the conference modality is an element on the XML about the IM being enabled or not (<im available="true"> or <im available="false">), but nothing about the session having video available or not. When handling _IUccConferenceSessionEvents.OnEnter, check the Media property on the UccConferenceSession. Don't work, all media types are present (MESSAGE, AUDIO, VIDEO, DATA e TELEPHONY), regardless of the type of conference I'm being invited. Also when handling _IUccConferenceSessionEvents.OnEnter, check the Entities collection on the UccConferenceView object, to check which MCUs are enabled for this conference. Don't work either, all MUCs are listed as available (IM, AV, DATA and CONTROL), regardless of the type of conference I'm being invited. I'm running out of ideas. Some references I'm using: http://msdn.microsoft.com/en-us/library/bb664307.aspx http://msdn.microsoft.com/en-us/library/dd170830.aspx Thanks a lot.

  • Debugger Visualizer, ElementHost, and Edit and Continue problems

    - by Frank Fella
    I recently wrote a custom Debugger Visualizer for Visual Studio 2008 for one of the custom types in my application. The UI for the visualizer is written in WPF and is hosted in an element host and shown using the IDialogVisualizerService windowService object. Everything works great, and my visualizer loads and shows the relevant information, but if try to "edit and continue" in my application after loading the visualizer, Visual Studio crashes with no useful error message. In trying to debug this I removed almost all of my code from the solution to the point where I was only serializing a string with the ObjectSource and displaying just an empty element host and I still get the crash on edit and continue. If I remove the element host and show a WinForms control or form there is no crash. Here is the Visualizer code: using System; using System.Drawing; using System.IO; using System.Runtime.Serialization.Formatters.Binary; using System.Windows.Forms; using System.Windows.Forms.Integration; using Microsoft.VisualStudio.DebuggerVisualizers; using ObjectVisualizerShared; using ObjectVisualizerUI; namespace ObjectVisualizer { public class Visualizer : DialogDebuggerVisualizer { protected override void Show(IDialogVisualizerService windowService, IVisualizerObjectProvider objectProvider) { try { Stream stream = objectProvider.GetData(); if (stream.Length > 0) { BinaryFormatter formatter = new BinaryFormatter(); VisualizerNode node = (VisualizerNode)formatter.Deserialize(stream); if (node != null) { VisualizerWindow window = new VisualizerWindow(node); ElementHost host = new ElementHost(); host.Child = window; host.Dock = DockStyle.Fill; host.Size = new Size(800, 600); windowService.ShowDialog(host); } } } catch (Exception ex) { MessageBox.Show(string.Format("Error!\n{0}", ex), "Object Visualizer"); } } } } Any ideas?

  • Mutability design patterns in Objective C and C++

    - by Mac
    Having recently done some development for iPhone, I've come to notice an interesting design pattern used a lot in the iPhone SDK, regarding object mutability. It seems the typical approach there is to define an immutable class NSFoo, and then derive from it a mutable descendant NSMutableFoo. Generally, the NSFoo class defines data members, getters and read-only operations, and the derived NSMutableFoo adds on setters and mutating operations. Being more familiar with C++, I couldn't help but notice that this seems to be a complete opposite to what I'd do when writing the same code in C++. While you certainly could take that approach, it seems to me that a more concise approach is to create a single Foo class, mark getters and read-only operations as const functions, and also implement the mutable operations and setters in the same class. You would then end up with a mutable class, but the types Foo const*, Foo const& etc all are effectively the immutable equivalent. I guess my question is, does my take on the situation make sense? I understand why Objective-C does things differently, but are there any advantages to the two-class approach in C++ that I've missed? Or am I missing the point entirely? Not an overly serious question - more for my own curiosity than anything else.

  • How to write a C program using the fork() system call that generates the Fibonacci sequence in the

    - by Ellen
    The problem I am having is that when say for instance the user enters 7, then the display shows: 0 11 2 3 5 8 13 21 child ends. I cannot seem to figure out how to fix the 11 and why is it displaying that many numbers in the sequence! Can anyone help? The number of the sequence will be provided in the command line. For example, if 5 is provided, the first five numbers in the Fibonacci sequence will be output by the child process. Because the parent and child processes have their own copies of the data, it will be necessary for the child to output the sequence. Have the parent invoke the wait() call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that a non-negative number is passed on the command line. #include <stdio.h> #include <sys/types.h> #include <unistd.h> int main() { int a=0, b=1, n=a+b,i,ii; pid_t pid; printf("Enter the number of a Fibonacci Sequence:\n"); scanf("%d", &ii); if (ii < 0) printf("Please enter a non-negative integer!\n"); else { pid = fork(); if (pid == 0) { printf("Child is producing the Fibonacci Sequence...\n"); printf("%d %d",a,b); for (i=0;i<ii;i++) { n=a+b; printf("%d ", n); a=b; b=n; } printf("Child ends\n"); } else { printf("Parent is waiting for child to complete...\n"); wait(NULL); printf("Parent ends\n"); } } return 0; }

  • Invalid security validation exception inside a SharePoint workflow

    - by Dan Revell
    I'm having a strange security problem with a SharePoint workflow. Particular calls seem to result in the following exception: Microsoft.SharePoint.SPException: The security validation for this page is invalid. I've come across this error before and the simple fix is web.AllowUnsafeUpdates = true; ... web.AllowUnsafeUpdates = false; However I've never once encountered this problem inside a workflow before since a workflow runs as system. I first got this error in a code activity where I set the value of a column on the list item. Wrapping the item.Update in AllowUnsafeUpdates fixed it. After the code activity I have a CreateTask activity. This also causes the same error but only after running the code inside the activity's MethodInvoking. In both cases there's a SPListItem.UpdateItem involved within the stack trace. This call is failing a security check. I don't know anything about how this check works so I don't know where to look next. This is a strange one, because this SharePoint dev machine has been working fine for some time. No other projects or workflows exhibit this behaviour so that rules out an installation problem. There's just something about this particular workflow. [UPDATE] I've gotten around the issue by just creating a new project and building it up again. I still have the broken one and I'd still like to figure out the problem with it. I'd appreciate any suggestions of what it might be.

  • Creating A Single Generic Handler For Agatha?

    - by David
    I'm using the Agatha request/response library (and StructureMap, as utilized by Agatha 1.0.5.0) for a service layer that I'm prototyping, and one thing I've noticed is the large number of handlers that need to be created. It generally makes sense that any request/response type pair would need their own handler. However, as this scales to a large enterprise environment that's going to be A LOT of handlers. What I've started doing is dividing up the enterprise domain into logical processor classes (dozens of processors instead of many hundreds or possibly eventually thousands handlers). The convention is that each request/response type (all of which inherit from a domain base request/response pair, which inherit from Agatha's) gets exactly one function in a processor somewhere. The generic handler (which inherits from Agatha's RequestHandler) then uses reflection in the Handle method to find the method for the given TREQUEST/TRESPONSE and invoke it. If it can't find one or if it finds more than one, it returns a TRESPONSE containing an error message (messages are standardized in the domain's base response class). The goal here is to allow developers across the enterprise to just concern themselves with writing their request/response types and processor functions in the domain and not have to spend additional overhead creating handler classes which would all do exactly the same thing (pass control to a processor function). However, it seems that I still need to have defined a handler class (albeit empty, since the base handler takes care of everything) for each request/response type pair. Otherwise, the following exception is thrown when dispatching a request to the service: StructureMap Exception Code: 202 No Default Instance defined for PluginFamily Agatha.ServiceLayer.IRequestHandler`1[[TSFG.Domain.DTO.Actions.HelloWorldRequest, TSFG.Domain.DTO, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], Agatha.ServiceLayer, Version=1.0.5.0, Culture=neutral, PublicKeyToken=6f21cf452a4ffa13 Is there a way that I'm not seeing to tell StructureMap and/or Agatha to always use the base handler class for all request/response type pairs? Or maybe to use Reflection.Emit to generate empty handlers in memory at application start just to satisfy the requirement? I'm not 100% familiar with these libraries and am learning as I go along, but so far my attempts at both those possible approaches have been unsuccessful. Can anybody offer some advice on solving this, or perhaps offer another approach entirely?

  • search and replace with ruby regex

    - by randombits
    I have a text blob field in a MySQL column that contains HTML. I have to change some of the markup, so I figured I'll do it in a ruby script. Ruby is irrelevant here, but it would be nice to see an answer with it. The markup looks like the following: <h5>foo</h5> <table> <tbody> </tbody> </table> <h5>bar</h5> <table> <tbody> </tbody> </table> <h5>meow</h5> <table> <tbody> </tbody> </table> I need to change just the first <h5>foo</h5> block of each text to <h2>something_else</h2> while leaving the rest of the string alone. Can't seem to get the proper PCRE regex, using Ruby.

  • Gridview empty when SelectedIndexChanged called

    - by xan
    I have a DataGrid which is being bound dynamically to a database query. The user enters some search text into a text field, clicks search, and the code behind creates the appropriate database query using LINQ (searches a table based on the string and returns a limited set of the columns). It then sets the GridView datasource to be the query and calls DataBind(). protected void btnSearch_Click(object sender, EventArgs e) { var query = from record in DB.Table where record.Name.Contains(txtSearch.Text) //Extra string checking etc. removed. select new { record.ID, record.Name, record.Date }; gvResults.DataSource = query; gvResults.DataBind(); } This works fine. When a user selects a row in the grid, the SelectedIndexChanged event handler gets the id from the row in the grid (one of the fields), queries the full record from the DB and then populates a set of editor / details fields with the records full details. protected void gvResults_SelectedIndexChanged(object sender, EventArgs e) { int id = int.Parse(gvResults.SelectedRow.Cells[1].Text); DisplayDetails(id); } This works fine on my local machine where I'm developing the code. On the production server however, the function is called successfully, but the row and column count on gvResults, the GridVeiw is 0 - the table is empty. The GridView's viewstate is enabled and I can't see obvious differences. Have I made some naive assumptions, or am I relying on something that is likely to be configured differently in debug? Locally I am running an empty asp.net web project in VS2008 to make development quicker. The production server is running the sitecore CMS so is configured rather differently. Any thoughts or suggestions would be most welcome. Thanks in advance!

  • Looking for ideas how to refactor my (complex) algorithm

    - by _simon_
    I am trying to write my own Game of Life, with my own set of rules. First 'concept', which I would like to apply, is socialization (which basicaly means if the cell wants to be alone or in a group with other cells). Data structure is 2-dimensional array (for now). In order to be able to move a cell to/away from a group of another cells, I need to determine where to move it. The idea is, that I evaluate all the cells in the area (neighbours) and get a vector, which tells me where to move the cell. Size of the vector is 0 or 1 (don't move or move) and the angle is array of directions (up, down, right, left). This is a image with representation of forces to a cell, like I imagined it (but reach could be more than 5): Let's for example take this picture: Forces from lower left neighbour: down (0), up (2), right (2), left (0) Forces from right neighbour : down (0), up (0), right (0), left (2) sum : down (0), up (2), right (0), left (0) So the cell should go up. I could write an algorithm with a lot of if statements and check all cells in the neighbourhood. Of course this algorithm would be easiest if the 'reach' parameter is set to 1 (first column on picture 1). But what if I change reach parameter to 10 for example? I would need to write an algorithm for each 'reach' parameter in advance... How can I avoid this (notice, that the force is growing potentialy (1, 2, 4, 8, 16, 32,...))? Can I use specific design pattern for this problem? Also: the most important thing is not speed, but to be able to extend initial logic. Things to take into consideration: reach should be passed as a parameter i would like to change function, which calculates force (potential, fibonacci) a cell can go to a new place only if this new place is not populated watch for corners (you can't evaluate right and top neighbours in top-right corner for example)

  • How does 'lazy' work?

    - by Matt Fenwick
    What is the difference between these two functions? I see that lazy is intended to be lazy, but I don't understand how that is accomplished. -- | Identity function. id :: a -> a id x = x -- | The call '(lazy e)' means the same as 'e', but 'lazy' has a -- magical strictness property: it is lazy in its first argument, -- even though its semantics is strict. lazy :: a -> a lazy x = x -- Implementation note: its strictness and unfolding are over-ridden -- by the definition in MkId.lhs; in both cases to nothing at all. -- That way, 'lazy' does not get inlined, and the strictness analyser -- sees it as lazy. Then the worker/wrapper phase inlines it. -- Result: happiness Tracking down the note in MkId.lhs (hopefully this is the right note and version, sorry if it's not): Note [lazyId magic] ~~~~~~~~~~~~~~~~~~~ lazy :: forall a?. a? -> a? (i.e. works for unboxed types too) Used to lazify pseq: pseq a b = a `seq` lazy b Also, no strictness: by being a built-in Id, all the info about lazyId comes from here, not from GHC.Base.hi. This is important, because the strictness analyser will spot it as strict! Also no unfolding in lazyId: it gets "inlined" by a HACK in CorePrep. It's very important to do this inlining after unfoldings are exposed in the interface file. Otherwise, the unfolding for (say) pseq in the interface file will not mention 'lazy', so if we inline 'pseq' we'll totally miss the very thing that 'lazy' was there for in the first place. See Trac #3259 for a real world example. lazyId is defined in GHC.Base, so we don't have to inline it. If it appears un-applied, we'll end up just calling it. I don't understand that because it refers to lazyId instead of lazy. How does lazy work?
