  • ASP.NET MVC partial view does not call my Action

    - by Johannes
    I just started building a small simple Website on ASP.NET MVC, in a page I am using a Partial view, the Partial View represents a simple Form which should be submitted on button click, and If I click the first Time it is submitted with success and does return my partial view with my validation Messages (if the content is invalid) but if I wish to try again the Action isn't called again. Any Idea? View: <form action="<%= Url.Action("ChangePassword", "Account") %>" method="post" id="jform"> <div> <fieldset> <legend>Account Information</legend> <p> <label for="currentPassword">Current password:</label> <%= Html.Password("currentPassword") %> <%= Html.ValidationMessage("currentPassword") %> </p> <p> <label for="newPassword">New password:</label> <%= Html.Password("newPassword") %> <%= Html.ValidationMessage("newPassword") %> </p> <p> <label for="confirmPassword">Confirm new password:</label> <%= Html.Password("confirmPassword") %> <%= Html.ValidationMessage("confirmPassword") %> </p> <p> <input type="submit" value="Change Password" /> </p> </fieldset> </div> </form> <!--<% } %>--> </div> <script> $(function() { $('#jform').submit(function() { $('#jform').ajaxSubmit({ target: '#FmChangePassword' }); return false; }); }); /*$(document).ready(function() { $('#jform').live('submit', function() { $.post($(this).attr('action'), $(this).serialize(), function(data) { $("#jform").replaceWith($(data)); }); return false; }); });*/ </script> Part of the Controller: if (!ValidateChangePassword(currentPassword, newPassword, confirmPassword)) { return PartialView(ViewData); }

  • Encrypted AES key too large to Decrypt with RSA (Java)

    - by Petey B
    Hello, I am trying to make a program that Encrypts data using AES, then encrypts the AES key with RSA, and then decrypt. However, once i encrypt the AES key it comes out to 128 bytes. RSA will only allow me to decrypt 117 bytes or less, so when i go to decrypt the AES key it throws an error. Relavent code: KeyPairGenerator kpg = KeyPairGenerator.getInstance("RSA"); kpg.initialize(1024); KeyPair kpa = kpg.genKeyPair(); pubKey = kpa.getPublic(); privKey = kpa.getPrivate(); updateText("Private Key: " +privKey +"\n\nPublic Key: " +pubKey); updateText("Encrypting " +infile); //Genereate aes key KeyGenerator kgen = KeyGenerator.getInstance("AES"); kgen.init(128); // 192/256 SecretKey aeskey = kgen.generateKey(); byte[] raw = aeskey.getEncoded(); SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES"); updateText("Encrypting data with AES"); //encrypt data with AES key Cipher aesCipher = Cipher.getInstance("AES"); aesCipher.init(Cipher.ENCRYPT_MODE, skeySpec); SealedObject aesEncryptedData = new SealedObject(infile, aesCipher); updateText("Encrypting AES key with RSA"); //encrypt AES key with RSA Cipher cipher = Cipher.getInstance("RSA"); cipher.init(Cipher.ENCRYPT_MODE, pubKey); byte[] encryptedAesKey = cipher.doFinal(raw); updateText("Decrypting AES key with RSA. Encrypted AES key length: " +encryptedAesKey.length); //decrypt AES key with RSA Cipher decipher = Cipher.getInstance("RSA"); decipher.init(Cipher.DECRYPT_MODE, privKey); byte[] decryptedRaw = cipher.doFinal(encryptedAesKey); //error thrown here because encryptedAesKey is 128 bytes SecretKeySpec decryptedSecKey = new SecretKeySpec(decryptedRaw, "AES"); updateText("Decrypting data with AES"); //decrypt data with AES key Cipher decipherAES = Cipher.getInstance("AES"); decipherAES.init(Cipher.DECRYPT_MODE, decryptedSecKey); String decryptedText = (String) aesEncryptedData.getObject(decipherAES); updateText("Decrypted Text: " +decryptedText); Any idea on how to get around this?

  • Setting up NCover for NUnit in FinalBuilder

    - by Lasse V. Karlsen
    I am attempting to set up NCover for usage in my FinalBuilder project, for a .NET 4.0 C# project, but my final coverage output file contains no coverage data. I am using: NCover 3.3.2 NUnit 2.5.4 FinalBuilder 6.3.0.2004 All tools are the latest official as of today. I've finally managed to coax FB into running my unit tests under NCover for the .NET 4.0 project, so I get Tests run: 184, ..., which is correct. However, the final Coverage.xml file output from NCover is almost empty, and looks like this: <?xml version="1.0" encoding="utf-8"?> <!-- saved from NCover 3.0 Export url='http://www.ncover.com/' --> <coverage profilerVersion="3.3.2.6211" driverVersion="3.3.2" exportversion="3" viewdisplayname="" startTime="2010-04-22T08:55:33.7471316Z" measureTime="2010-04-22T08:55:35.3462915Z" projectName="" buildid="27c78ffa-c636-4002-a901-3211a0850b99" coveragenodeid="0" failed="false" satisfactorybranchthreshold="95" satisfactorycoveragethreshold="95" satisfactorycyclomaticcomplexitythreshold="20" satisfactoryfunctionthreshold="80" satisfactoryunvisitedsequencepoints="10" uiviewtype="TreeView" viewguid="C:\Dev\VS.NET\LVK.IoC\LVK.IoC.Tests\bin\Debug\Coverage.xml" viewfilterstyle="None" viewreportstyle="SequencePointCoveragePercentage" viewsortstyle="Name"> <rebasedpaths /> <filters /> <documents> <doc id="0" excluded="false" url="None" cs="" csa="00000000-0000-0000-0000-000000000000" om="0" nid="0" /> </documents> </coverage> The output in FB log is: ... ***************** End Program Output ***************** Execution Time: 1,5992 s Coverage Xml: C:\Dev\VS.NET\LVK.IoC\LVK.IoC.Tests\bin\Debug\Coverage.xml NCover Success My configuration of the FB step for NCover: NCover what?: NUnit test coverage Command: C:\Program Files (x86)\NUnit 2.5.4\bin\net-2.0\nunit-console.exe Command arguments: LVK.IoC.Tests.dll /noshadow /framework:4.0.30319 /process=single /nothread Note: I've tried with and without the /process and /nothread options Working directory: %FBPROJECTDIR%\LVK.IoC.Tests\bin\Debug List of assemblies to profile: %FBPROJECTDIR%\LVK.IoC.Tests\bin\Debug\LVK.IoC.dll Note: I've tried just listing the name of the assembly, both with and without the extension. The documentation for the FB step doesn't help, as it only lists minor sentences for each property, and fails to give examples or troubleshooting hints. Since I want to pull the coverage results into NDepend to run build-time analysis, I want that file to contain the information I need. I am also using TestDriven, and if I right-click the solution file and select "Test with NCover", NCover-explorer opens up with coverage data, and if I ask it to show me the folder with coverage files, in there is an .xml file with the same structure as the one above, just with all the data that should be there, so the tools I have is certainly capable of producing it. Has anyone an idea of what I've configured wrong here?

  • IronPython and Nodebox in C#

    - by proxylittle
    My plan: I'm trying to setup my C# project to communicate with Nodebox to call a certain function which populates a graph and draws it in a new window. Current situation: [fixed... see Update2] I have already included all python-modules needed, but im still getting a Library 'GL' not found it seems that the pyglet module needs a reference to GL/gl.h, but can't find it due to IronPython behaviour. Requirement: The project needs to stay as small as possible without installing new packages. Thats why i have copied all my modules into the project-folder and would like to keep it that or a similar way. My question: Is there a certain workaround for my problem or a fix for the library-folder missmatch. Have read some articles about Tao-Opengl and OpenTK but can't find a good solution. Update1: Updated my sourcecode with a small pyglet window-rendering example. Problem is in pyglet and referenced c-Objects. How do i include them in my c# project to be called? No idea so far... experimenting alittle now. Keeping you updated. SampleCode C#: ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null); ScriptRuntime runtime = new ScriptRuntime(setup); ScriptEngine engine = Python.GetEngine(runtime); ScriptSource source = engine.CreateScriptSourceFromFile("test.py"); ScriptScope scope = engine.CreateScope(); source.Execute(scope); SampleCode Python (test.py): from nodebox.graphics import * from nodebox.graphics.physics import Vector, Boid, Flock, Obstacle flock = Flock(50, x=-50, y=-50, width=700, height=400) flock.sight(80) def draw(canvas): canvas.clear() flock.update(separation=0.4, cohesion=0.6, alignment=0.1, teleport=True) for boid in flock: push() translate(boid.x, boid.y) scale(0.5 + boid.depth) rotate(boid.heading) arrow(0, 0, 15) pop() canvas.size = 600, 300 def main(canvas): canvas.run(draw) Update2: Line 139 [pyglet/lib.py] sys.platform is not win32... there was the error. Fixed it by just using the line: from pyglet.gl.lib_wgl import link_GL, link_GLU, link_WGL Now the following Error: 'module' object has no attribute '_getframe' Kind of a pain to fix it. Updating with results... Update3: Fixed by adding following line right after first line in C#-Code: setup.Options["Frames"] = true; Current Problem: No module named unicodedata, but in Python26/DLLs is only a *.pyd file`. So.. how do i implement it now?!

  • Delphi native Web Service applications not working. IIS 7 seems to be stripping the pathinfo

    - by Cary Jensen
    I've run into an interesting problem that I never encountered with XP or IIS 6. Basically, I can't get a native Delphi (WebBroker) Web service server to work with a native Web service client in Windows 7 64-bit. Here's the most basic breakdown. If I create a new Web service application in Delphi 2010 (or any version, back to Delphi 7), and access it using IE 8, I can see the HTML that the WSDLHTMLPublish component creates, but I can never get to the SOAP. In the same way, the WSDL Importer cannot get to the SOAP either. (I have IIS 7 configured to use a 32-bit application pool, and I have created a working Script Map to the Handler Mappings. In short, the 32-bit ISAPI Web service is running). For example, I have a simple Web service server named TestService (created using the default sample interface generated when you create a new Web service server). I installed it in a virtual directory named scripts. If I enter http://localhost/scripts/TestService.dll/wsdl, IIS 7 displays the page http://localhost/scripts/TestService.dll. If I put my mouse over the WSDL link for the ITestService, I see http://localhost/scripts/TestService.dll/wsdl/ITestService in the status bar. However, when I click this link, the address bar shows http://localhost/scripts/TestService.dll/wsdl/ITestService, but I see only the HTML from http://localhost/scripts/TestService.dll. There seems no way to get to the SOAP definition. IIS 7 seems to be ignoring everything after the script name (it is ignoring the pathinfo). Additional evidence that IIS7 is stripping off the pathinfo is that if I pause my mouse over the ITestService link, the statusbar shows http://localhost/scripts/TestService.dll?intf=ITestService. Clicking that link takes me to another HTML page, the one associated with http://localhost/scripts/TestService.dll?intf=ITestService. However, any link that includes a pathinfo following the script name, takes me simply to http://localhost/scripts/TestService.dll. I have tested this in Delphi 7, Delphi 2010, and Delphi XE, with the same results. I am guessing that IIS7 is stripping off the pathinfo, since even the WSDL Importer cannot get to the SOAP definition. Tried creating a new Web service using the CGI option, and got the same result. Have any idea what is going on? Added: Bob Swart reports he has had no problems under Windows 7 32-bit. Downloading the 32-bit OS and will try that (in a new VM).

  • Oracle 9i Session Disconnections

    - by mlaverd
    [Cross-Posting from ServerFault] I am in a development environment, and our test Oracle 9i server has been misbehaving for a few days now. What happens is that we have our JDBC connections disconnecting after a few successful connections. We got this box set up by our IT department and handed over to. It is 'our problem', so options like 'ask you DBA' isn't going to help me. :( Our server is set up with 3 plain databases (one is the main dev db, the other is the 'experimental' dev db). We use the Oracle 10 ojdbc14.jar thin JDBC driver (because of some bug in the version 9 of the driver). We're using Hibernate to talk to the DB. The only thing that I can see that changed is that we now have more users connecting to the server. Instead of one developer, we now have 3. With the Hibernate connection pools, I'm thinking that maybe we're hitting some limit? Anyone has any idea what's going on? Here's the stack trace on the client: Caused by: org.hibernate.exception.GenericJDBCException: could not execute query at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:126) [hibernate3.jar:na] at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:114) [hibernate3.jar:na] at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) [hibernate3.jar:na] at org.hibernate.loader.Loader.doList(Loader.java:2235) [hibernate3.jar:na] at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2129) [hibernate3.jar:na] at org.hibernate.loader.Loader.list(Loader.java:2124) [hibernate3.jar:na] at org.hibernate.loader.hql.QueryLoader.list(QueryLoader.java:401) [hibernate3.jar:na] at org.hibernate.hql.ast.QueryTranslatorImpl.list(QueryTranslatorImpl.java:363) [hibernate3.jar:na] at org.hibernate.engine.query.HQLQueryPlan.performList(HQLQueryPlan.java:196) [hibernate3.jar:na] at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1149) [hibernate3.jar:na] at org.hibernate.impl.QueryImpl.list(QueryImpl.java:102) [hibernate3.jar:na] ...

  • Using commit monitors as a form of code review

    - by Jeff Dege
    I'm working in a small company - four developers, working on a variety of projects. We've been looking at what we can do as cost-effective methods of process improvement, and an idea came up. Given what we do, we often have single developers working on parts of a system, independently of the other developers. This can have a number of negative affects: A developer might not be fully aware of the context in which a change is being implemented, and make the change in a way that will meet the current customer's needs, but will break functionality that other customers depend on. A developer might make a change that breaks the current architectural design, introducing a dependency that will cause problems in future development. Other developers might not be aware of how the system has changed, in areas that they have not worked on. We've talked about doing code reviews, as a way of dealing with these issues. But we've not had much success when we tried. It takes a lot of time to prepare a change for a code review, and it takes everybody out of production while the review is being performed. And the benefits of any review we've tried has been minimal. We're using Subversion (with TortioseSVN) as our VCS. I've been looking at the SubVersion CommitMonitor tool, and wondering whether it might work as a sort of poor-man's code review. It lists every commit made on the repository, allowing someone to see the changes that have been made, the log messages made for that change, the files that were included in the change, and the specific lines in each file that were changed. Rather than scheduling a meeting, trying to get everybody together to review every change, we could just have every developer review every other developer's commits, at whatever time was convenient. This would keep every developer abreast of what changes were being made elsewhere in the system, and would have every change reviewed for customer conflicts and design consistency, at a fairly low cost. If someone saw a problem with the code that was being checked in, he could discuss it with the developer who did the commit, or more likely, schedule a meeting to discuss how the new feature could be implemented in a way that would not impact other users or screw up the architecture. Anyone else doing anything like this, using commit monitors for such a purpose?

  • Asynchronous readback from opengl front buffer using multiple PBO's

    - by KillianDS
    I am developing an application that needs to read back the whole frame from the front buffer of an openGL application. I can hijack the application's opengl library and insert my code on swapbuffers. At the moment I am successfully using a simple but excruciating slow glReadPixels command without PBO's. Now I read about using multiple PBO's to speed things up. While I think I've found enough resources to actually program that (isn't that hard), I have some operational questions left. I would do something like this: create a series (e.g. 3) of PBO's use glReadPixels in my swapBuffers override to read data from front buffer to a PBO (should be fast and non-blocking, right?) Create a seperate thread to call glMapBufferARB, once per PBO after a glReadPixels, because this will block until the pixels are in client memory. Process the data from step 3. Now my main concern is of course in steps 2 and 3. I read about glReadPixels used on PBO's being non-blocking, will this be an issue if I issue new opengl commands after that very fast? Will those opengl commands block? Or will they continue (my guess), and if so, I guess only swapbuffers can be a problem, will this one stall or will glReadPixels from front buffer be many times faster than swapping (about each 15-30ms) or, worst case scenario, will swapbuffers be executed while glReadPixels is still reading data to the PBO? My current guess is this logic will do something like this: copy FRONT_BUFFER - generic place in VRAM, copy VRAM-RAM. But I have no idea which of those 2 is the real bottleneck and more, what the influence on the normal opengl command stream is. Then in step 3. Is it wise to do this asynchronously in a thread separated from normal opengl logic? At the moment I think not, It seems you have to restore buffer operations to normal after doing this and I can't install synchronization objects in the original code to temporarily block those. So I think my best option is to define a certain swapbuffer delay before reading them out, so e.g. calling glReadPixels on PBO i%3 and glMapBufferARB on PBO (i+2)%3 in the same thread, resulting in a delay of 2 frames. Also, when I call glMapBufferARB to use data in client memory, will this be the bottleneck or will glReadPixels (asynchronously) be the bottleneck? And finally, if you have some better ideas to speed up frame readback from GPU in opengl, please tell me, because this is a painful bottleneck in my current system. I hope my question is clear enough, I know the answer will probably also be somewhere on the internet but I mostly came up with results that used PBO's to keep buffers in video memory and do processing there. I really need to read back the front buffer to RAM and I do not find any clear explanations about performance in that case (which I need, I cannot rely on "it's faster", I need to explain why it's faster). Thank you

  • Finding minimum cut-sets between bounded subgraphs

    - by Tore
    If a game map is partitioned into subgraphs, how to minimize edges between subgraphs? I have a problem, Im trying to make A* searches through a grid based game like pacman or sokoban, but i need to find "enclosures". What do i mean by enclosures? subgraphs with as few cut edges as possible given a maximum size and minimum size for number of vertices for each subgraph that act as a soft constraints. Alternatively you could say i am looking to find bridges between subgraphs, but its generally the same problem. Given a game that looks like this, what i want to do is find enclosures so that i can properly find entrances to them and thus get a good heuristic for reaching vertices inside these enclosures. So what i want is to find these colored regions on any given map. My Motivation The reason for me bothering to do this and not just staying content with the performance of a simple manhattan distance heuristic is that an enclosure heuristic can give more optimal results and i would not have to actually do the A* to get some proper distance calculations and also for later adding competitive blocking of opponents within these enclosures when playing sokoban type games. Also the enclosure heuristic can be used for a minimax approach to finding goal vertices more properly. A possible solution to the problem is the Kernighan-Lin algorithm: function Kernighan-Lin(G(V,E)): determine a balanced initial partition of the nodes into sets A and B do A1 := A; B1 := B compute D values for all a in A1 and b in B1 for (i := 1 to |V|/2) find a[i] from A1 and b[i] from B1, such that g[i] = D[a[i]] + D[b[i]] - 2*c[a][b] is maximal move a[i] to B1 and b[i] to A1 remove a[i] and b[i] from further consideration in this pass update D values for the elements of A1 = A1 / a[i] and B1 = B1 / b[i] end for find k which maximizes g_max, the sum of g[1],...,g[k] if (g_max > 0) then Exchange a[1],a[2],...,a[k] with b[1],b[2],...,b[k] until (g_max <= 0) return G(V,E) My problem with this algorithm is its runtime at O(n^2 * lg(n)), i am thinking of limiting the nodes in A1 and B1 to the border of each subgraph to reduce the amount of work done. I also dont understand the c[a][b] cost in the algorithm, if a and b do not have an edge between them is the cost assumed to be 0 or infinity, or should i create an edge based on some heuristic. Do you know what c[a][b] is supposed to be when there is no edge between a and b? Do you think my problem is suitable to use a multi level problem? Why or why not? Do you have a good idea for how to reduce the work done with the kernighan-lin algorithm for my problem?

  • Problems with makeObjectsPerformSelector inside and outside a class?

    - by QuakAttak
    A friend and I are creating a card game for the iPhone, and in these early days of the project, I'm developing a Deck class and a Card class to keep up with the cards. I'm wanting to test the shuffle method of the Deck class, but I am not able to show the values of the cards in the Deck class instance. The Deck class has a NSArray of Card objects that have a method called displayCard that shows the value and suit using console output(printf or NSLog). In order to show what cards are in a Deck instance all at once, I am using this, [deck makeObjectsPerformSelector:@selector(displayCard)], where deck is the NSArray in the Deck class. Inside of the Deck class, nothing is displayed on the console output. But in a test file, it works just fine. Here's the test file that creates its own NSArray: #import <Foundation/Foundation.h> #import "card.h" int main (int argc, char** argv) { NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init]; Card* two = [[Card alloc] initValue:2 withSuit:'d']; Card* three = [[Card alloc] initValue:3 withSuit:'h']; Card* four = [[Card alloc] initValue:4 withSuit:'c']; NSArray* deck = [NSArray arrayWithObjects:two,three,four,nil]; //Ok, what if we release the objects in the array before they're used? //I don't think this will work... [two release]; [three release]; [four release]; //Ok, it works... I wonder how... //Hmm... how will this work? [deck makeObjectsPerformSelector:@selector(displayCard)]; //Yay! It works fine! [pool release]; return 0; } This worked beautifully, so I created an initializer around this idea, creating 52 card objects one at a time and adding them to the NSArray using deck = [deck arrayByAddingObject:newCard]. Is the real problem with how I'm using makeObjectsPerformSelector or something before/after it?

  • List of objects sent over WCF, but null list received?

    - by GONeale
    Hey there, I have an object containing a list of custom objects which I am returning over a response in WCF, however on the receiving end, the list is null? But it contains 112 objects just prior to stepping out of the service on the server. This wasn't always the case, I have seen it return a list. I've just recently upgraded it to use NET TCP bindings, but I can't confirm when I started losing the data or if it was since the conversion from wsHttpBinding to netTcpBinding as it moved along with about four other services. I have looked on the WCF Service messages and trace file and also the WCF client's messages and trace file, no exceptions reported, and both message logs indicate they are sending the List<T> and for client, receiving the list - very frustrating! It's not a super light array, but not huge either, around 100KB. it has about 12 properties each and as stated 112 items are being sent. I have tried everything I can think of on client and server, note: Client: this.binding = new NetTcpBinding(SecurityMode.None) { MaxReceivedMessageSize = int.MaxValue, ReaderQuotas = { MaxStringContentLength = int.MaxValue, MaxArrayLength = int.MaxValue } }; ... Server app.config (sorry I have no idea if the quota settings have any bearing on net tcp? I only just added it similar to what I use for wsHttpBinding to test, but still list is null): <netTcpBinding> <binding name="SecurityByNetTcpTransportBinding" sendTimeout="00:03:00" maxReceivedMessageSize="2147483647"> <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" /> <security mode="None" /> </binding> </netTcpBinding> and something else I tried in my net tcp binding behavior: <dataContractSerializer maxItemsInObjectGraph="2147483647" /> <serviceTimeouts transactionTimeout="05:05:00" /> <serviceThrottling maxConcurrentSessions="400" maxConcurrentInstances="400" maxConcurrentCalls="400"/> I hope somebody can help, I hate 5 steps forward 3 steps backward which always seems to be the case with WCF :P In the interim until I [hopefully] get a response I will now try reducing this array just to see if it's a sizing issue.. Ok, It seems I have bigger problems. Because the list was the only thing I was sending, I thought it was an array issue. I am even setting an int to "25" and it's coming back as 0 - Anybody? I know I must have done something obviously stupid.

  • css - get rid of spaces between spans

    - by opensas
    I'm trying to emulate a tab bar with html I'd like the width of each tab to be set according to the text lenght (that is, no fixed width) and to word wrap in case it exceeds the screen width I've almost achieved it <html> <head> <style type="text/css"> #myTabs .tab { float: left; } #myTabs .tab_middle { margin: 0; padding: 0; border: none; background-image:url('images/tabs/tab_middle.png'); } #myTabs .tab_left { margin: 0; padding: 0; border: none; background-image:url('images/tabs/tab_left.png'); } #myTabs .tab_right { margin: 0; padding: 0; border: none; background-image:url('images/tabs/tab_right.png'); } </style> </head> <body> <div id="myTabs"> <div class='tab'> <span class='tab_left'>&nbsp;</span> <span class='tab_middle'>very very looong</span> <span class='tab_right'>&nbsp;</span> </div> <div class='tab'> <span class='tab_left'>&nbsp;</span> <span class='tab_middle'>another loooong tab</span> <span class='tab_right'>&nbsp;</span> </div> <div style='clear:both'></div> </div> </body> </html> but, there's a very annoying space between the opening tab image and the closing one... as you can see I've tried with padding, spacin, and border, with no luck... any idea? thanks a lot saludos sas -- edit I tried replacing the spans with a small table (one row, three TDs) but it's the same, only the space between is smaller...

  • preg_match to match an optional string, but not match all of the string

    - by buggedcom
    Take for example the following regex match. preg_match('!^publisher/([A-Za-z0-9\-\_]+)/([0-9]+)/([0-9]{4})-(january|february|march|april|may|june|july|august|september|october|november|december):([0-9]{1,2})-([0-9]{1,2})/([A-Za-z0-9\-\_]+)/([0-9]+)(/page-[0-9]+)?$!', 'publisher/news/1/2010-march:03-23/test_title/1/page-1', $matches); print_r($matches); It produces the following: Array ( [0] => publisher/news/1/2010-march:03-23/test_title/1/page-1 [1] => news [2] => 1 [3] => 2010 [4] => march [5] => 03 [6] => 23 [7] => test_title [8] => 1 [9] => /page-1 ) However as the last match is optional it can also work with matching the following "publisher/news/1/2010-march:03-23/test_title/1". My problem is that I want to be able to match (/page-[0-9]+) if it exists, but match only the page number so "publisher/news/1/2010-march:03-23/test_title/1/page-1" would match like so: Array ( [0] => publisher/news/1/2010-march:03-23/test_title/1/page-1 [1] => news [2] => 1 [3] => 2010 [4] => march [5] => 03 [6] => 23 [7] => test_title [8] => 1 [9] => 1 ) I've tried the following regex '!^publisher/([A-Za-z0-9\-\_]+)/([0-9]+)/([0-9]{4})-(january|february|march|april|may|june|july|august|september|october|november|december):([0-9]{1,2})-([0-9]{1,2})/([A-Za-z0-9\-\_]+)/([0-9]+)/?p?a?g?e?-?([0-9]+)?$!' This works, however it will also match "publisher/news/1/2010-march:03-23/test_title/1/1". I have no idea to perform a match but not have it come back in the matches? Is it possible in a single regex?

  • How to combine a relative top with an absolute bottom in CSS?

    - by ceving
    I need to define a div which must stay with the top at the normal position, which differs from the top of the surrounding element: position:relative top:0 and which grows in the height up to the size of the surrounding element: position:absolute bottom:0 I have no idea how to combine the both. Whenever I use a relative box I loose the absolute bottom and whenever I use an absolute box I loose the relative top. Can anybody help me how to do this in CSS? Here is an example: <html> <head> </head> <style type="text/css"> @media screen { body { position: absolute; top: 0; left: 0; right: 0; bottom: 0; margin: 0; padding: 0; } #head { background-color: gray; } #rel { background-color: green; position: relative; top: 0; bottom: 0; float: left; } #abs { background-color: red; position: absolute; top: 0; bottom: 0; float: left; } } </style> <body> <div id="head"> <h1>Head</h1> </div> <div id="abs"> <h2>absolute</h2> </div> <div id="rel"> <h2>relative</h2> </div> </body> </html> "relative" does not grow at all and "absolute" grows too much.

  • What should I do when the managed object context fails to save?

    - by dontWatchMyProfile
    Example: I have an Cat entity with an catAge attribute. In the data modeler, I configured catAge as int with a max of 100. Then I do this: [newManagedObject setValue:[NSNumber numberWithInt:125] forKey:@"catAge"]; // Save the context. NSError *error = nil; if (![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); } I'm getting an error in the console, like this: 2010-06-12 11:40:41.947 CatTest[2250:207] Unresolved error Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x10164d0 "Operation could not be completed. (Cocoa error 1610.)", { NSLocalizedDescription = "Operation could not be completed. (Cocoa error 1610.)"; NSValidationErrorKey = catAge; NSValidationErrorObject = <NSManagedObject: 0x10099f0> (entity: Cat; id: 0x1006a90 <x-coredata:///Cat/t3BCBC34B-8405-4F16-B591-BE804B6811562> ; data: { catAge = 125; catName = "No Name"; }); NSValidationErrorPredicate = SELF <= 100; NSValidationErrorValue = 125; } Well, so I have an validation error. But the odd thing is, that it seems the MOC is broken after this. If I just tap "add" to add another invalid Cat object and save that, I'm getting this: 2010-06-12 11:45:13.857 CatTest[2250:207] Unresolved error Error Domain=NSCocoaErrorDomain Code=1560 UserInfo=0x1232170 "Operation could not be completed. (Cocoa error 1560.)", { NSDetailedErrors = ( Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x1215f00 "Operation could not be completed. (Cocoa error 1610.)", Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x1209fc0 "Operation could not be completed. (Cocoa error 1610.)" ); } That seems to report two errors now. BUT: When I try to delete now an valid, existing object from the table view (using the default core data template in a navigation-based app), then the app crashes! All I get in the console is: 2010-06-12 11:47:18.931 CatTest[2250:207] Unresolved error Error Domain=NSCocoaErrorDomain Code=1560 UserInfo=0x123eb30 "Operation could not be completed. (Cocoa error 1560.)", { NSDetailedErrors = ( Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x1217010 "Operation could not be completed. (Cocoa error 1610.)", Error Domain=NSCocoaErrorDomain Code=1610 UserInfo=0x123ea80 "Operation could not be completed. (Cocoa error 1610.)" ); } ...so no idea where or why it crashes, but it does. So the question is, what are the neccessary steps to take when there's an validation error?

  • Problem with Google App Engine Appstats

    - by Taylor L
    I'm having an issue getting Appstats to work correctly. Using /appstats or /appstats/stats ends up in an infinite loop that keeps redirecting back to /appstats/stats. This results in a 404 error saying the page isn't redirecting properly. Any idea what the issue is? Here are the relevant lines in my appengine-web.xml. I've tried using both /appstats/stats and /appstats and they both have the same issue. <admin-console> <page name="Appstats" url="/appstats/stats" /> </admin-console> Below are the http headers showing the infinite redirect loop: http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcHiwT8jH7e01V9O5iFu3kpBhDd3k3oBwwxylv5u0DbJ- utvdpsgdb4Xim2WXwobkJmgTGGljvuh94_yVQ__- VPnBsTtUAhRjSyZ2Lv3G7oUHAxTsCWHJIMChGT3- XUyUNx8wxwvJisL_RTXH8Hc4TTLh_rVHm2k8gk8kgdbVZXexSV0K- a3coELTecWIBolt0qLd5L-5vALm382KsqbHorPXqoZMPTvR_06g_mR1cbmF2Ihnk6YhP7no58BNpESM9HvFyKNKXODo39hF4oaZCcW0Q9TBqUMgsrBqlcIh3- VvC7qvH0n_nAtrLTBbK_swnOFvCDcaf3whT9ty0CJ0VRNuNqIPOLHIeQAMgwXUNMr89P64EsgmuyONHR67glCQXEPOGXIaT1vcBJFwFoeNUqjdp824fHvoVhaL7Xlav- LTIFuM3f_ymHLmibk57PRuXUYEaAG HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.645553 X-AppEngine-Resource-Usage: ms=18965 cpu_ms=27884 api_cpu_ms=0 Set-Cookie: ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS; expires=Mon, 12-Apr-2010 19:41:49 GMT; path=/ Date: Sun, 11 Apr 2010 19:42:08 GMT Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Cache-Control: no-cache, must-revalidate Content-Type: text/html Server: Google Frontend Content-Length: 0 ---------------------------------------------------------- http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.002243 X-AppEngine-Resource-Usage: ms=64 cpu_ms=93 api_cpu_ms=0 Date: Sun, 11 Apr 2010 19:42:08 GMT Content-Type: text/html Server: Google Frontend Content-Length: 0

  • How can I close a Window using the OS-X ScriptingBridge framework, from Perl?

    - by Gavin Brock
    Problem... Since MacPerl is no longer supported on 64bit perl, I am trying alternative frameworks to control Terminal.app. I am trying the ScriptingBridge, but have run into a problem passing an enumerated string to the closeSaving method using the PerlObjCBridge. I want to call: typedef enum { TerminalSaveOptionsYes = 'yes ' /* Save the file. */, TerminalSaveOptionsNo = 'no ' /* Do not save the file. */, TerminalSaveOptionsAsk = 'ask ' /* Ask the user whether or not to save the file. */ } TerminalSaveOptions; - (void) closeSaving:(TerminalSaveOptions)saving savingIn:(NSURL *)savingIn; // Close a document. Attempted Solution... I have tried: #!/usr/bin/perl use strict; use warnings; use Foundation; # Load the ScriptingBridge framework NSBundle->bundleWithPath_('/System/Library/Frameworks/ScriptingBridge.framework')->load; @SBApplication::ISA = qw(PerlObjCBridge); # Set up scripting bridge for Terminal.app my $terminal = SBApplication->applicationWithBundleIdentifier_("com.apple.terminal"); # Open a new window, get back the tab my $tab = $terminal->doScript_in_('exec sleep 60', undef); warn "Opened tty: ".$tab->tty->UTF8String; # Yes, it is a tab # Now try to close it # Simple idea eval { $tab->closeSaving_savingIn_('no ', undef) }; warn $@ if $@; # Try passing a string ref my $no = 'no '; eval { $tab->closeSaving_savingIn_(\$no, undef) }; warn $@ if $@; # Ok - get a pointer to the string my $pointer = pack("P4", $no); eval { $tab->closeSaving_savingIn_($pointer, undef) }; warn $@ if $@; eval { $tab->closeSaving_savingIn_(\$pointer, undef) }; warn $@ if $@; # Try a pointer decodes as an int, like PerlObjCBridge uses my $int_pointer = unpack("L!", $pointer); eval { $tab->closeSaving_savingIn_($int_pointer, undef) }; warn $@ if $@; eval { $tab->closeSaving_savingIn_(\$int_pointer, undef) }; warn $@ if $@; # Aaarrgghhhh.... As you can see, all my guesses at how to pass the enumerated string fail. Before you flame me... I know that I could use another language (ruby, python, cocoa) to do this but that would require translating the rest of the code. I might be able to use CamelBones, but I don't want to assume my users have it installed. I could also use the NSAppleScript framework (assuming I went to the trouble of finding the Tab and Window IDs) but it seems odd to have to resort to it for just this one call.

  • Crawling not working windows2008

    - by axtolf
    Hi, We installed a new MOSS 2007 farm on windows 2008 SP2 enviroment. We used SQL2008 too. Configuration is 1 index, 1 FE and 1 server with 2008, all on ESX 4.0. All the Service that need it uses a dedicated user, so search has a dedicated user. Installation went well and we found no problem. We installed an SP1 MOSS from a ISO and after we upgraded WSS and MOSS to SP2. We installed the Italian language pack too and patched it to SP2. We created a new SSP. We created a web application and created a root website under it. The problem is that we can't male crawling work in any way. Seems that crawling is not able to reach the web application that we want to crawl. In event viewer of the index we have this error when we try to crawl it: The start address <h..p://name.domain.it:81 cannot be crawled. Context: Application 'SSP1', Catalog 'Portal_Content' Details: The object was not found. (0x80041201) The log of crawling from the search admin, only says: h..p://name.domani.it:81 The object was not found. (The item was deleted because it was either not found or the crawler was denied access to it.) The domain is fully accessible from everywhere using both farm admin user or the search user that we are using for service to run. Site is fully accessible from the index and seem not have problem. Inside the we application we created a root site collection with a couple of file. The log of the farm simply says.... nothing! When we ask to do a full crawl of the site, it runs for a second and after we have the errors that I wrote above. But the farm's log says nothing. Any suggestion or help is really appreciated since we are losing a lot of time on it and really we do not have any idea of what's wrong about this farm.

  • Why does this CSS example use "height: 1%" with "overflow: auto"?

    - by Lawrence Lau
    I am reading a HTML and CSS book. It has a sample code of two-column layout. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <style> #main {height: 1%; overflow: auto;} #main, #header, #footer {width: 768px; margin: auto;} #bodycopy { float: right; width: 598px; } #sidebar {margin-right: 608px; } #footer {clear: both; } </style> </head> <body> <div id="header" style='background-color: #AAAAAA'>This is the header.</div> <div id="main" style='background-color: #EEEEEE'> <div id="bodycopy" style='background-color: #BBBBBB'> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> This is the principal content.<br /> </div> <div id="sidebar" style='background-color: #CCCCCC'> This is the sidebar. </div> </div> <div id="footer" style='background-color: #DDDDDD'>This is the footer.</div> </body> </html> The author mentions that the use of overflow auto and 1% height will make the main area expand to encompass the computed height of content. I try to remove the 1% height and tried in different browsers but they don't show a difference. I am quite confused of its use. Any idea?

  • Ajax comments form in ASP.NET MVC2, howto?

    - by Artiom Chilaru
    I've been playing around with different aspects of MVC for some time now, and I've reached a situation where I'm not sure what would be the best way to solve a problem. I'm hoping that the SO community will help me out here :P I've seen a number of examples of Ajax.BeginForm on the internet, and it seems like a very nifty idea. E.g. you have a dropdown where you select a customer - and on selecting one it will load this client's details in some placeholder on the page. This works perfectly fine. But what to do if you want to tie in some validation in the box? Just hypothetically, imagine an article page, and user comments in the bottom. Below the comments area there's an ajax-y "Add comment" box. When a user adds a comment, it will appear in the comments area, below the last comment there. If I set the Ajax.BeginForm to Append the result of the call to the Comments area, it will work fine. But what if the data posted is not valid? Instead of appending a "successful" comment to the comments area I have to show the user validation errors. At this point I decided that the area INSIDE the Ajax.BeginForm will be inside a partial, and the form's submits will return this partial. Validation works fine. On each submit we reload the contents inside the form element. But how to add the successful comment to the top? Other things to consider: The comment form also has a "Preview" button. When the user clicks on Preview, I should load the rendered comment into a preview box. This will probably be inside the form area as well. I was thinking of using Json results instead. When the user submits the form, the server code will generate a Json object with a Success value, and html rendered partials as some properties. Something like { "success": true, "form": "<html form data>", "comment": "successful comment html to inject into the page" } This would be a perfect solution, except there's no way in MVC to render a partial into a string, inside the controller (separation of context, remember?). So.. what should I do then? Any "correct" way to implement this? Anyone???

  • Haskell: Left-biased/short-circuiting function

    - by user2967411
    Two classes ago, our professor presented to us a Parser module. Here is the code: module Parser (Parser,parser,runParser,satisfy,char,string,many,many1,(+++)) where import Data.Char import Control.Monad import Control.Monad.State type Parser = StateT String [] runParser :: Parser a -> String -> [(a,String)] runParser = runStateT parser :: (String -> [(a,String)]) -> Parser a parser = StateT satisfy :: (Char -> Bool) -> Parser Char satisfy f = parser $ \s -> case s of [] -> [] a:as -> [(a,as) | f a] char :: Char -> Parser Char char = satisfy . (==) alpha,digit :: Parser Char alpha = satisfy isAlpha digit = satisfy isDigit string :: String -> Parser String string = mapM char infixr 5 +++ (+++) :: Parser a -> Parser a -> Parser a (+++) = mplus many, many1 :: Parser a -> Parser [a] many p = return [] +++ many1 p many1 p = liftM2 (:) p (many p) Today he gave us an assignment to introduce "a left-biased, or short-circuiting version of (+++)", called (<++). His hint was for us to consider the original implementation of (+++). When he first introduced +++ to us, this was the code he wrote, which I am going to call the original implementation: infixr 5 +++ (+++) :: Parser a -> Parser a -> Parser a p +++ q = Parser $ \s -> runParser p s ++ runParser q s I have been having tons of trouble since we were introduced to parsing and so it continues. I have tried/am considering two approaches. 1) Use the "original" implementation, as in p +++ q = Parser $ \s - runParser p s ++ runParser q s 2) Use the final implementation, as in (+++) = mplus Here are my questions: 1) The module will not compile if I use the original implementation. The error: Not in scope: data constructor 'Parser'. It compiles fine using (+++) = mplus. What is wrong with using the original implementation that is avoided by using the final implementation? 2) How do I check if the first Parser returns anything? Is something like (not (isNothing (Parser $ \s - runParser p s) on the right track? It seems like it should be easy but I have no idea. 3) Once I figure out how to check if the first Parser returns anything, if I am to base my code on the final implementation, would it be as easy as this?: -- if p returns something then p <++ q = mplus (Parser $ \s -> runParser p s) mzero -- else (<++) = mplus Best, Jeff

  • Unable to cast lists with Reflection in C#

    - by DrLazer
    I am having a lot of trouble with Reflection in C# at the moment. The app I am writing allows the user to modify the attributes of certain objects using a config file. I want to be able to save the object model (users project) to XML. The function below is called in the middle of a foreach loop, looping through a list of objects that contain all the other objects in the project within them. The idea is, that it works recursively to translate the object model into XML. Dont worry about the call to "Unreal" that just modifes the name of the objects slightly if they contain certain words. private void ReflectToXML(object anObject, XmlElement parentElement) { Type aType = anObject.GetType(); XmlElement anXmlElement = m_xml.CreateElement(Unreal(aType.Name)); parentElement.AppendChild(anXmlElement); PropertyInfo[] pinfos = aType.GetProperties(); //loop through this objects public attributes foreach (PropertyInfo aInfo in pinfos) { //if the attribute is a list Type propertyType = aInfo.PropertyType; if ((propertyType.IsGenericType)&&(propertyType.GetGenericTypeDefinition() == typeof(List<>))) { List<object> listObjects = (aInfo.GetValue(anObject,null) as List<object>); foreach (object aListObject in listObjects) { ReflectToXML(aListObject, anXmlElement); } } //attribute is not a list else anXmlElement.SetAttribute(aInfo.Name, ""); } } If an object attributes are just strings then it should be writing them out as string attributes in the XML. If an objects attributes are lists, then it should recursively call "ReflectToXML" passing itself in as a parameter, thereby creating the nested structure I require that nicely reflect the object model in memory. The problem I have is with the line List<object> listObjects = (aInfo.GetValue(anObject,null) as List<object>); The cast doesn't work and it just returns null. While debugging I changed the line to object temp = aInfo.GetValue(anObject,null); slapped a breakpoint on it to see what "GetValue" was returning. It returns a "Generic list of objects" Surely I should be able to cast that? The annoying thing is that temp becomes a generic list of objects but because i declared temp as a singular object, I can't loop through it because it has no Enumerator. How can I loop through a list of objects when I only have it as a propertyInfo of a class? I know at this point I will only be saving a list of empty strings out anyway, but thats fine. I would be happy to see the structure save out for now. Thanks in advance
