  • Symfony form->bind fails

    - by Shawn Craver
    I'm working with a few custom forms, and one of them isn't binding it's values on a POST. I'm using the same logic for each, and only one of them isn't working. Here's the code: public function executeMediaFileUpload(sfWebRequest $request) { $this->form = new MediaFileUploadForm(); if (!$request->isMethod('POST')) $psk = $request->getParameter('psk'); else { $this->form->bind($request->getParameter($this->form->getName()), $request->getFiles($this->form->getName())); $this->logMessage('VALUE: ' . $this->form->getValue('version')); $psk = $this->form->getValue('application'); } $this->logMessage('PSK: ' . $psk); $app = Doctrine::getTable('Application')->find(array($psk)); $this->form->setDefault('application', $app->getPsk()); $this->form->setDefault('version', $app->getVersion()->getLast()->getPsk()); On the initial GET, I can see the value passed in via psk getting set as the default for application in the generated HTML, and all the values show up in the POST request in Firebug, but after I bind the form, it still contains no values.

  • Code management in different projects with different svn repositories

    - by uzay95
    First of all I want to tell you what kind of system I have and I want to build on. 1- A Solution (has) a- Shared Class Library project (which is for lots of different solutions) b- Another Class Library project (which is only for this solution) c- Web Application project (which main part of this solution) d- Shared Web Service project (which also serves for different solutions) 2- B Solution (has) a- Shared Class Library project (which is for lots of different solutions) c- Windows Form Application project (which is main part of this solution) d- Web Service project (which also serves for different solutions) and other projects like that.... I am using xp-dev.com as our svn repository server. And I opened different projects for these items (Shared Class Library, Web Service project, Windows Form Application project, Web Application project, Another Class Library project) . I want to do the versioning of all these projects of course. My first question is, should I put each project(one solution) to one svn repository to get their revision number later on? Or should I put each of them to different svn repository and keep( write down) their correct version number that is used to publish/deploy every solution? If I use one svn for each project(Shared Class Lib, Web App, Shared Web Service....) how can I relate the right svn address and version on VS.2010 within the real solution? So, how do you manage your repositories and projects?

  • Send SOAP via curl

    - by danrichardson
    Hi. This has been bugging me for days, i'm trying to send a SOAP post via curl but i just keep getting a 'couldn't connect to host' error but i really cant see how. I have an asp version which works fine with the same url and data, i think it's just a php/curl thing...? I currently have the following code (the CURLOPT_POSTFIELDS data is a valid soap envelope string) $soap_do = curl_init(); curl_setopt($soap_do, CURLOPT_URL, "https://xxx.yyy.com:517/zzz.asmx" ); curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10); curl_setopt($soap_do, CURLOPT_TIMEOUT, 10); curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true ); curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($soap_do, CURLOPT_POST, true ); curl_setopt($soap_do, CURLOPT_POSTFIELDS, '<soap:Envelope>...</soap:Envelope>'); curl_setopt($soap_do, CURLOPT_HTTPHEADER, array('Content-Type: text/xml; charset=utf-8', 'Content-Length: '.strlen('<soap:Envelope>...</soap:Envelope>') )); if(curl_exec($soap_do) === false) { $err = 'Curl error: ' . curl_error($soap_do); curl_close($soap_do); return $err; } else { curl_close($soap_do); return 'Operation completed without any errors'; } So any ideas why it just errors all the time? The asp version works fine! The code is; Set xmlhttp = server.Createobject("MSXML2.ServerXMLHTTP") xmlhttp.Open "POST","https://xxx.yyy.com:517/zzz.asmx" xmlhttp.setRequestHeader "Content-Type", "text/xml; charset=utf-8" xmlhttp.Send('<soap:Envelope>...</soap:Envelope>')

  • If I cast an IQueryable as an IEnumerable then call a Linq extension method, which implementation gets called?

    - by James Morcom
    Considering the following code: IQueryable<T> queryable; // something to instantiate queryable var enumerable = (IEnumerable<T>) queryable; var filtered = enumerable.Where(i => i > 3); In the final line, which extension method gets called? Is it IEnumerable<T>.Where(...)? Or will IQueryable<T>.Where(...) be called because the actual implementation is still obviously a queryable? Presumably the ideal would be for the IQueryable version to be called, in the same way that normal polymorphism will always use the more specific override. In Visual Studio though when I right-click on the Where method and "Go to Definition" I'm taken to the IEnumerable version, which kind of makes sense from a visual point-of-view. My main concern is that if somewhere in my app I use Linq to NHibernate to get a Queryable, but I pass it around using an interface that uses the more general IEnumerable signature, I'll lose the wonders of deferred database execution!

  • Java applet wont run

    - by Courtney
    I am trying to get a Java applet to run properly when linked to an HTML page in Dreamweaver CC. I'm new to all this so please bear with me here. First I saved this code to a .java file //Triangle.java import java.awt.*; import java.applet.Applet; public class Triangle extends Applet { public void paint (Graphics g){ int bottomX=80; int bottomY=200; int base=100; int height=100; g.drawLine(bottomX,bottomY,bottomX+base,bottomY); g.drawLine(bottomX+base,bottomY,bottomX+base/2,bottomY-height); g.drawLine(bottomX+base/2,bottomY-height, bottomX,bottomY); } } I then compiled it entering javac Triangle.java After that, I inserted it into a Dreamwever page using: <html> <applet code=Triangle.class width=400 height=400 > </applet> </html> Now when I try and open the page in Chrome I get an error reading: UnsupportedClassVersionError Triangle: Unsupported major.minor version 52.0 This, as I have read, is an issue with using two incompatible Java versions? In my Java Control Panel it says I am using version 1.8.0_20 and my JDK is jdk1.8.0_20. Does anyone see anything super obvious that I am doing wrong here?

  • .NET Embedded Manifest Crashes XP

    - by Alan Spark
    Hi, I am embedding a manifest in a .NET exe so that it can request elevated permissions in Vista and Windows 7. The manifest that I am using is as follows: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" name="ElevationTest" type="win32"/> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level="requireAdministrator"/> </requestedPrivileges> </security> </trustInfo> </assembly> It works as expected in Vista and Windows 7 but crashes XP with the standard "... has encountered a problem and needs to close..." error. If I don't embed any manifest then it works as expected but will obviously not have the required permissions in Vista and Windows 7. What is a standard way of producing an exe that will function with the correct permissions in XP and Vista / Windows 7? Thanks, Alan

  • Type-safe generic data structures in plain-old C?

    - by Bradford Larsen
    I have done far more C++ programming than "plain old C" programming. One thing I sorely miss when programming in plain C is type-safe generic data structures, which are provided in C++ via templates. For sake of concreteness, consider a generic singly linked list. In C++, it is a simple matter to define your own template class, and then instantiate it for the types you need. In C, I can think of a few ways of implementing a generic singly linked list: Write the linked list type(s) and supporting procedures once, using void pointers to go around the type system. Write preprocessor macros taking the necessary type names, etc, to generate a type-specific version of the data structure and supporting procedures. Use a more sophisticated, stand-alone tool to generate the code for the types you need. I don't like option 1, as it is subverts the type system, and would likely have worse performance than a specialized type-specific implementation. Using a uniform representation of the data structure for all types, and casting to/from void pointers, so far as I can see, necessitates an indirection that would be avoided by an implementation specialized for the element type. Option 2 doesn't require any extra tools, but it feels somewhat clunky, and could give bad compiler errors when used improperly. Option 3 could give better compiler error messages than option 2, as the specialized data structure code would reside in expanded form that could be opened in an editor and inspected by the programmer (as opposed to code generated by preprocessor macros). However, this option is the most heavyweight, a sort of "poor-man's templates". I have used this approach before, using a simple sed script to specialize a "templated" version of some C code. I would like to program my future "low-level" projects in C rather than C++, but have been frightened by the thought of rewriting common data structures for each specific type. What experience do people have with this issue? Are there good libraries of generic data structures and algorithms in C that do not go with Option 1 (i.e. casting to and from void pointers, which sacrifices type safety and adds a level of indirection)?

  • Odd Things of ASP.NET MVC Deployment on IIS 6

    - by misaxi
    Recently, I am a bit interested in the deployment of ASP.NET MVC application on IIS6 because Phil Haack posted an easier way to deploy ASP.NET MVC application on ASP.NET 4. So I decided to see how different version of ASP.NET MVC works on different version of ASP.NET. First off, I created an ASP.NET MVC 2 project in Visual Studio 2010 and deploy it to IIS 6 on Windows Server 2003 (only .NET framework 3.5 installed). I set the application to run in ASP.NET 2.0 and no extra stuff. Because I just wanted to see what sort of error would occur. And as expected, some error was reported as following. Then, I set the Copy Local attribute of System.Web.Mvc assembly to true as following and deploy again. As a result, the application ran smoothly. I had read tons of materials talked about the mess of deploying MVC application on IIS 6. And I did fight to tackle the deploying issues in my previous project. At least, if had used Extensionless Url in your application, you should have configured wildcard mapping in IIS. But in this case, I even didn’t have chance to do so. What the heck was going on exactly? Did I discover a new continent?

  • View Source and Chrome Developer Tools showing different output

    - by patricksweeney
    I have a page located here. Viewing it in Chrome and Firefox show a really small h1 title, and also it changes color as if it is a link. The template that generates everything looks exactly how it should be. When diagnosing the issue, the relevant section of code looks like this when I go to view source: <div class="page-heading"> <h1>Title Here</h1> </div> However, when I go to view it in Chrome's Developer tools, it is throwing in extraneous malformed anchor tags, which is obviously causing the hovering behavior. This is what it looks like to the dev tools: <div class="page-heading"> <h1> <a style="font-family: arial; font-size: 9px" <="" a="">Title Here</a> </h1> </div> In addition, when viewing a local copy of the site, the output shown in the dev tools is the same as viewing the source and they both render correctly locally. Oddly enough, all version of IE render it correctly. The current version of both Chrome and Firefox both render it weirdly. Initially I thought it may be a user agent stylesheet problem, but if anything the CSS is fine, it's the HTML that is malformed.

  • A better solution than element.Elements("Whatever").First()?

    - by codeka
    I have an XML file like this: <SiteConfig> <Sites> <Site Identifier="a" /> <Site Identifier="b" /> <Site Identifier="c" /> </Sites> </SiteConfig> The file is user-editable, so I want to provide reasonable error message in case I can't properly parse it. I could probably write a .xsd for it, but that seems kind of overkill for a simple file. So anyway, when querying for the list of <Site> nodes, there's a couple of ways I could do it: var doc = XDocument.Load(...); var siteNodes = from siteNode in doc.Element("SiteConfig").Element("SiteUrls").Elements("Sites") select siteNode; But the problem with this is that if the user has not included the <SiteUrls> node (say) it'll just throw a NullReferenceException which doesn't really say much to the user about what actually went wrong. Another possibility is just to use Elements() everywhere instead of Element(), but that doesn't always work out when coupled with calls to Attribute(), for example, in the following situation: var siteNodes = from siteNode in doc.Elements("SiteConfig") .Elements("SiteUrls") .Elements("Sites") where siteNode.Attribute("Identifier").Value == "a" select siteNode; (That is, there's no equivalent to Attributes("xxx").Value) Is there something built-in to the framework to handle this situation a little better? What I would prefer is a version of Element() (and of Attribute() while we're at it) that throws a descriptive exception (e.g. "Looking for element <xyz> under <abc> but no such element was found") instead of returning null. I could write my own version of Element() and Attribute() but it just seems to me like this is such a common scenario that I must be missing something...

  • Problem with LINQ to XML and Namespaces

    - by abtcabe
    I am having problems with working with a third party XML string that contains a Namespace with LINQ to XML. In the below code everything works find. I am able to select the xElement (xEl1) and update its value. 'Example Without Namespace Dim XmlWithOutNs = _ <?xml version="1.0"?> <RATABASECALC> <RATEREQUEST> <ANCHOR> <DATABASENAME>DatabaseName</DATABASENAME> <DATABASEPW>DatabasePw</DATABASEPW> </ANCHOR> </RATEREQUEST> </RATABASECALC> Dim xEl1 = XmlWithOutNs...<DATABASEPW>.FirstOrDefault If xEl1 IsNot Nothing Then xEl1.Value = "test" End If However, in the below code the xElement (xEl2) returns Nothing. The only difference is the Namespace (xmlns="http://www.cgi.com/Ratabase) 'Example With Namespace Dim XmlWithNs = _ <?xml version="1.0"?> <RATABASECALC xmlns="http://www.cgi.com/Ratabase"> <RATEREQUEST> <ANCHOR> <DATABASENAME>DatabaseName</DATABASENAME> <DATABASEPW>DatabasePw</DATABASEPW> </ANCHOR> </RATEREQUEST> </RATABASECALC> Dim xEl2 = XmlWithNs...<DATABASEPW>.FirstOrDefault If xEl2 IsNot Nothing Then xEl2.Value = "test" End If So my questions are: 1. Why is this happening? 2. How do I resolve this issue?

  • visual studio attaching to a process in debug mode

    - by user1612986
    i have a strange problem. the dll that i built (lets call it my.dll) in c++ visual studio 2010 uses a third party library (say tp.lib) which in turn calls a third party dll (say tp.dll). for debugging prupose i have in configurationProperties-debugging-command: Excel.exe and configurationProperties-debugging-commandArguments: "$(TargetPath)" in my computer i also set PATH variable to the directory where tp.dll resides now when i hit the F5 in visual studio excel opens up with my.dll and crashes giving me a "cannot open in dos mode" error. the reason this happens is tp.dll is not deployed when debug version of my.dll is deployed. when i open an instance of excel seperately and manually drop the debug version of my.dll then everything works fine and i can see all my functions that i wrote in my.dll the only issue is now i do not know how to debug becuase i do not know how to attach visual studio to the instance of excel i opened up seperately. my question is: 1 how can i attach visual studio to an already opened instance of Excel or 2 how can i hit F5 and still make Excel pick up the required tp.dll from the directory specified in the PATH variable before it starts to deploy my.dll. any of these two will allow my to step through the code for the purpose of debugging. thanks in advance.

  • issue with keychain and updates from app store

    - by xonegirlz
    I am having a very frustrating error. I have tested for an app upgrade by first installing the previous version (1.0.1) and then running version (1.0.2). Everything worked fine. I submitted the app and then I am getting issues people are getting crashes when they upgrade.

  • Source code dependency manager for C++

    - by 7vies
    There are already some questions about dependency managers here, but it seems to me that they are mostly about build systems, while I am looking for something targeted purely at making dependency tracking and resolution simpler (and I'm not necessarily interested in learning a new build system). So, typically we have a project and some common code with another project. This common code is organized as a library, so when I want to get the latest code version for a project, I should also go get all the libraries from the source control. To do this, I need a list of dependencies. Then, to build the project I can reuse this list too. I've looked at Maven and Ivy, but I'm not sure if they would be appropriate for C++, as they look quite heavily java-targeted (even though there might be plugins for C++, I haven't found people recommending them). I see it as a GUI tool producing some standardized dependency list which can then be parsed by different scripts etc. It would be nice if it could integrate with source control (tag, get a tagged version with dependencies etc), but that's optional. Would you have any suggestions? Maybe I'm just missing something, and usually it's done some other way with no need for such a tool? Thanks.

  • Dealloc'd Predicate crashing iPhone App!

    - by DVG
    To preface, this is a follow up to an inquiry made a few days ago: http://stackoverflow.com/questions/2981803/iphone-app-crashes-when-merging-managed-object-contexts Short Version: EXC_BAD_ACCESS is crashing my app, and zombie-mode revealed the culprit to be my predicate embedded within the fetch request embedded in my Fetched Results Controller. How does an object within an object get released without an explicit command to do so? Long Version: Application Structure Platforms View Controller - Games View Controller (Predicated upon platform selection) - Add Game View Controller When a row gets clicked on the Platforms view, it sets an instance variable in Games View for that platform, then the Games Fetched Results Controller builds a fetch request in the normal way: - (NSFetchedResultsController *)fetchedResultsController{ if (fetchedResultsController != nil) { return fetchedResultsController; } //build the fetch request for Games NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Game" inManagedObjectContext:context]; [request setEntity:entity]; //predicate NSPredicate *predicate = [NSPredicate predicateWithFormat:@"platform == %@", selectedPlatform]; [request setPredicate:predicate]; //sort based on name NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; //fetch and build fetched results controller NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:context sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [sortDescriptor release]; [sortDescriptors release]; [predicate release]; [request release]; [aFetchedResultsController release]; return fetchedResultsController; } At the end of this method, the fetchedResultsController's _fetch_request - _predicate member is set to an NSComparisonPredicate object. All is well in the world. By the time - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section gets called, the _predicate is now a Zombie, which will eventually crash the application when the table attempts to update itself. I'm more or less flummoxed. I'm not releasing the fetched results controller or any of it's parts, and the only part getting dealloc'd is the predicate. Any ideas?

  • What do I need to do besides code?

    - by user151841
    I'm a single-person operation for my small employer. I'm working on a couple of web applications that have grown to medium-size. We have backups going and everything is in version control with Subversion. I have comments in my code, but documentation outside of code is "spotty at best", and frequently things change. What do I need to do to bring it to the next level, beyond a pile of ( version-controlled, well-commented ) code? What would you say is required to have a robust set of documentation outside of the codebase itself, where the project is at, and where it's going? Ideally I would like some integrated system that would go from brainstorm, to requirements, to tracking bugs and features in svn check-in messages, to documentation. Would trac or redmine do something like this? I would like to show to my boss, "This is the prioritized list of features, this is where we are now, this is how long I spend on this feature, how long I spent on this bug" and I'd like to spend the minimum amount of time managing the projects :) What about ERD and UML diagrams? Is a project incomplete without them?

  • Properly obsoleting old members in an XML Serializable class in C# VB .NET

    - by George
    Hi! Some time ago I defined a class that was serialized using XML. That class contained a serializable propertyA of integer type. Now I have extended and updated this class, whereby a new propertyB was added, whose type is another class that also has several serializable properties. The new propertyB is now supposed to play the role of propertyA, that is since type of propertyB is another class, one of its members would contain the value that previously propertyA contained, thus making peroptyA obsolete. What I am trying to figure out is how do I make sure that when I desireliaze the OLD version of this class (without propertyB in it), I make sure that the desreializer would take the value of propertyA from the old calss and set it as a value of one of the members of propertyB in a new class? Private WithEvents _Position As Position = New Position(Alignment.MiddleMiddle, 0, True, 0, True) Public Property Position() As Position 'NEW composite property that holds the value of the obsolted property, i.e. Alignment Get Return _Position End Get Set(ByVal value As Position) _Position = value End Set End Property Private _Alignment As Alignment = Alignment.MiddleMiddle <Xml.Serialization.XmlIgnore(), Obsolete("Use Position property instead.")> _ Public Property Alignment() As Alignment'The old, obsoleted property that I guess must be left for compliance with deserializing the old version of this class Get Return _Alignment End Get Set(ByVal value As Alignment) _Alignment = value End Set End Property Can you help me, please?

  • Design Pattern for Changing Object

  • License For (Mostly) Open Source Website / Service

    - by Ryan Sullivan
    I have an interesting setup and am not sure how to license a website. I know this is not legal advice, and I am not asking for any. There are so many different Open Source Licenses and I do not have the time to read every last one to see which best fits my situation. Really, I am looking for suggestions and a nudge in the right direction. My setup is: I give away for free version of my web service with a clean website interface. The implementation I use in the actual web site is (almost) identical to what I give away. The main service works the exactly the same way, but the website interface to manage features in the service is fairly different. Really the web interfaces have the same exact backend, and the front ends accomplish the same tasks, but the service I offer on my site is very rich and uses a good deal of javascript, where I kept the interface in the version I give away as simple and javascript-less as possible. Mostly so it is easy to understand and integrate into other sites. I am not entirely sure how I should license this. It is more like I develop an open source service but have a separate site built upon it. I like the GPLv3 but I am not sure if I can use it in this case especially since I am making some money off of google ad's on the site and plan on using amazon affiliates as well. Any help would be greatly appreciated. I do want to open it up as much as possible. But I still want to be able to continue with my own implementation. Thanks in advance for any information or help anyone can provide.

  • C# WTF? Can anyone explain the strange behaviour?

    - by partizan
    Hi, guys. Here is the example with comments: class Program { // first version of structure public struct D1 { public double d; public int f; } // during some changes in code then we got D2 from D1 // Field f type became double while it was int before public struct D2 { public double d; public double f; } static void Main(string[] args) { // Scenario with the first version D1 a = new D1(); D1 b = new D1(); a.f = b.f = 1; a.d = 0.0; b.d = -0.0; bool r1 = a.Equals(b); // gives true, all is ok // The same scenario with the new one D2 c = new D2(); D2 d = new D2(); c.f = d.f = 1; c.d = 0.0; d.d = -0.0; bool r2 = c.Equals(d); // false, oops! this is not the result i've expected for } } So, what do you think about this?

  • .NET remoting: System references wrong .NET dll, but how to cure ?

    - by Quandary
    Question: I defined an interface like below. The problem now is, that when I add the dll (API.dll) as reference in an asp.net project, it references a wrong API.dll, though I referenced the correct dll. In turn, it doesn't find GetLDAPlookup, but there is another method that is not in defined here, but in an older version of API.dll... I rebuilt the dll I referenced, so it is definitely the latest version that I added as reference. Do I have to add another GUID, or something ? Imports System.Runtime.InteropServices Namespace RemoteObject ''' <summary> ''' Defines server interface which will be deployed on every client ''' </summary> ''' <GuidAttribute("921DE547-32FA-40BB-961A-EA390B7AE27D")> _ Public Interface IServerMethods ''' <summary> ''' Function to call the server from the client ''' </summary> ''' <param name="strMessage">Some text</param> ''' Sub ServerPrint(ByVal strMessage As String) ''' <summary> ''' Function to call the server from the client ''' </summary> ''' <param name="strMessage">Some text</param> ''' <returns>Some interesting text</returns> ''' Function GetLDAPlookup(ByVal strMessage As String) As System.Data.DataSet End Interface End Namespace

  • Why is function's length information of other shared lib in ELF?

    - by minastaros
    Our project (C++, Linux, gcc, PowerPC) consists of several shared libraries. When releasing a new version of the package, only those libs should change whose source code was actually affected. With "change" I mean absolute binary identity (the checksum over the file is compared. Different checksum - different version according to the policy). (I should mention that the whole project is always built at once, no matter if any code has changed or not per library). Usually this can by achieved by hiding private parts of the included Header files and not changing the public ones. However, there was a case where just a delete was added to the destructor of a class TableManager (in the TableManager.cpp file!) of library libTableManager.so, and yet the binary/checksum of library libB.so (which uses class TableManager ) has changed. TableManager.h: class TableManager { public: TableManager(); ~TableManager(); private: int* myPtr; } TableManager.cpp: TableManager::~TableManager() { doSomeCleanup(); delete myPtr; // this delete has been added } By inspecting libB.so with readelf --all libB.so, looking at the .dynsym section, it turned out that the length of all functions, even the dynamically used ones from other libraries, are stored in libB! It looks like this (length is the 668 in the 3rd column): 527: 00000000 668 FUNC GLOBAL DEFAULT UND _ZN12TableManagerD1Ev So my questions are: Why is the length of a function actually stored in the client lib? Wouldn't a start address be sufficient? Can this be suppressed somehow when compiling/linking of libB.so (kind of "stripping")? We would really like to reduce this degree of dependency...
