  • PHP session destroyed / lost after header

    - by ILMV
    I've got a script that sets some session values before redirecting to / using header(). I've read many posts about the $_SESSION variable being destroyed / lost after header(), even after I implemented this: // set session here session_regenerate_id(true); session_write_close(); header("Location: /"); session_start() is set in the correct places, does anyone know of anything that I might be missing? On the index.php page I have this: session_start(); print_r($_SESSION); // outputs nothing :'( The code is pretty complex so will not post it all, just snippets.

  • What is the difference between a constructor and a procedure in Delphi records?

    - by HMcG
    Is there difference in behavior between a constructor call and a procedure call in Delphi records? I have a D2010 code sample I want to convert to D2009 (which I am using). The sample uses a parameterless constructor, which is not permitted in Delphi 2009. If I substitute a simple parameterless procedure call, is there any functional difference for records? I.E. TVector = record private FImpl: IVector; public constructor Create; // not allowed in D2009 end; becomes TVector = record private FImpl: IVector; public procedure Create; // so change to procedure end; As far as I can see this should work, but I may be missing something.

  • Why does addSubview load the view asynchronously

    - by moshe
    I have a UIView that I want to load when the user clicks a button. There happens to be some data processing that happens as well after I call addSubview that involves parsing an XML file retrieved from the web. The problem is the view doesn't show up until after the data processing even if addSuview is called first. I think I'm missing something here, can anyone help? Code: I have a "Loading..." view I'm adding as a custom modal (meaning I'm not using the modalViewController). This action is linked to a button in the navigationController. - (IBAction)parseXml:(id)sender { LoadingModalViewController *loadingModal = [[LoadingModalViewController alloc] initWithNibName:@"LoadingModalViewController" bundle:nil]; [navigationController.view addSubview:loadingModal.view]; [xmlParser parse]; }

  • "No architectures" error when compiling objective flickr for iphone device

    - by user176723
    I'm getting the following error when I attempt to compile my XCode project to debug on my device. No architectures to compile for (ARCHS=x86_64, VALID_ARCHS=armv6 armv7). I've included ObjectiveFlickr in my project just as the readme describes. I've gone through the process several times and redownloaded objectiveFlickr a few times to start over. I've gotten objectiveFlickr to work on devices in the past. I don't know why I am suddenly having trouble. Can anybody point me to something that might hold the clue I need? Any other info I need to provide? I made only changes to my project that are specified by the OF documentation. I also get this error when compiling the included snap-n-run example project provided with OF. So I must be missing something beneath my project. Thanks, Charlie

  • Bad event on java panel

    - by LucaB
    Hi I have a java panel with 4 buttons. When I click on of these buttons, a new frame appears and the first is hidden with setVisibile(false). On that new window, I have another button, but when i click it, I got the event corresponding to the fourth button of the first window. Clicking the button again does the trick, but of course this is not acceptable. Am I missing something? I just show the frames with nameOfTheFrame.setVisible(true); and I have MouseListeners on every button. The code of the last button is simply: System.exit(0); EDIT Sample code: private void btn_joinGamePressed(java.awt.event.MouseEvent evt) { GraphicsTools.getInstance().getCreateGame().setVisible(false); GraphicsTools.getInstance().getMainPanel().setVisible(false); GraphicsTools.getInstance().getRegistration().setVisible(true); } GraphicsTools is a Singleton.

  • SQL - Two foreign keys that have a dependency between them

    - by Brian
    The current structure is as follows: Table RowType: RowTypeID Table RowSubType: RowSubTypeID FK_RowTypeID Table ColumnDef: FK_RowTypeID FK_RowSubTypeID (nullable) In short, I'm mapping column definitions to rows. In some cases, those rows have subtype(s), which will have column definitions specific to them. Alternatively, I could hang those column definitions that are specific to subtypes off their own table, or I could combine the data in RowType and RowSubType into one table and work with a single ID, but I'm not sure either is a better solution (if anything, I'd lean towards the latter, as we mostly end up pulling ColumnDefs for a given RowType/RowSubType). Is the current design SQL Blasphemy? If I keep the current structuree, how do I maintain that if RowSubTypeID is specified in ColumnDef, that it must correspond to the RowType specified by RowTypeID? Should I try to enforce this with a trigger or am I missing a simple redesign that would solve the problem?

  • Pure-JavaScript projects in NetBeans?

    - by Matt Zukowski
    This seems like it ought to be obvious, yet I can't figure it out. I do a lot of JavaScript coding, and I really like NetBeans. Unfortunately I can't figure out how to create a "JavaScript" project in NetBeans. If I go to File - New Project, my only options are "Java", "Ruby", and "NetBeans Modules". I don't want any of these. My project consists mostly of JavaScript, with a little bit of CSS. I ususally just end up creating a "Ruby" project, but this seems retarded, since I don't actually have any Ruby code. Why isn't there an option to create a "JavaScript" or "Web" project, or at least a "Generic" project that doesn't revolve around a specific language? Am I missing something here?

  • Using C# Type as generic

    - by I Clark
    I'm trying to create a generic list from a specific Type that is retrieved from elsewhere: Type listType; // Passed in to function, could be anything var list = _service.GetAll<listType>(); However I get a build error of: The type or namespace name 'listType' could not be found (are you missing a using directive or an assembly reference?) Is this even possible or am I setting foot onto C# 4 Dynamic territory? As a background: I want to automatically load all lists with data from the repository. The code below get's passed a Form Model whose properties are iterated for any IEnum (where T inherits from DomainEntity). I want to fill the list with objects of the Type the list made of from the repository. public void LoadLists(object model) { foreach (var property in model.GetType() .GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.SetProperty)) { if (IsEnumerableOfNssEntities(property.PropertyType)) { var listType = property.PropertyType.GetGenericArguments()[0]; var list = _repository.Query<listType>().ToList(); property.SetValue(model, list, null); } } }

  • return a php associative array to javascript array

    - by Eric Sim
    I am trying to return a php associative array to javascript array through ajaxRequest.responseText Here's what I do. First in php, I do this: $encoded = json_encode($thisarray); echo $encoded; If I echo $encoded, I get {"a":"apple,arrow","b":"boy,bank","c":"cat,camp"} Then in js script, thisarray = new Array(); thisarray = ajaxRequest.responseText; If I alert thisarray, I get {"a":"apple,arrow","b":"boy,bank","c":"cat,camp"} That's wrong since alerting an array should give error. But in this case, when I alert thisarray, I get the full array!! Needless to say, I can't call my value out of thisarray, since it is yet defined as an array. Anyone can tell me what am I missing here?

  • JQuery.ajax success function returns empty

    - by viatropos
    I have a very basic AJAX function in JQuery: $.ajax({ url: "http://www.google.com", dataType: "html", success: function(data) { alert(data); } }); But the data is always an empty string, no matter what url I go to... Why is that? I am running this locally at http://localhost:3000, and am using JQuery 1.4.2. If I make a local response, however, like this: $.ajax({ url: "http://localhost:3000/test", dataType: "html", success: function(data) { alert(data); } }); ...it returns the html page at that address. What am I missing here?

  • Tomcat 6 configuration example for Ubuntu Linux?

    - by intargc
    I'm very new to Tomcat and I'm having some issues figuring out how to set it up. I set it up on Ubuntu Linux and started reading and trying to follow the information given on the apache website here: http://tomcat.apache.org/tomcat-6.0-doc/deployer-howto.html Apparently I'm missing something. I have a WAR named MyWebapp.war and it's in a directory /home/mywebapp. In /etc/tomcat6/Catalina/localhost/MyWebapp.xml, I have the following line: <Context path="/MyWebapp" docBase="/home/mywebapp" antiResourceLocking="false" /> Everything else is the default configuration that came with tomcat6 via the Ubuntu package. When I restart Tomcat and try to go to http://localhost:8080/MyWebapp, I get a 404. The WAR file isn't unpacked and nothing seems to be working. I'm going to be deploying two Grails applications on this server with Tomcat. Is there a more straight forward way to do this?

  • Undefined symbols when attempting to use CoverStory with iPhone app: _vproc_transaction_end

    - by dbarker
    After following these steps to set up an iphone project with CoverStory, my build fails with two linker errors. Undefined symbols: "_vproc_transaction_end", referenced from: _gcov_exit in libgcov.a(_gcov.o) _vproc_transaction_end$non_lazy_ptr in libgcov.a(_gcov.o) (maybe you meant: _vproc_transaction_end$non_lazy_ptr) "_vproc_transaction_begin", referenced from: ___gcov_init in libgcov.a(_gcov.o) _vproc_transaction_begin$non_lazy_ptr in libgcov.a(_gcov.o) (maybe you meant: _vproc_transaction_begin$non_lazy_ptr) ld: symbol(s) not found collect2: ld returned 1 exit status The second error is similar to above, except for _vproc_transaction_begin. I'm using Xcode 3.2, GCC 4.2 on Snow Leopard. Any ideas what I'm missing?

  • Can't Use Generic C# Class in Using Statement

    - by Eric J.
    I'm trying to use a generic class in a using statement but the compiler can't seem to treat it as implementing IDisposable. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.Objects; namespace Sandbox { public sealed class UnitOfWorkScope<T> where T : ObjectContext, IDisposable, new() { public void Dispose() { } } public class MyObjectContext : ObjectContext, IDisposable { public MyObjectContext() : base("DummyConnectionString") { } #region IDisposable Members void IDisposable.Dispose() { throw new NotImplementedException(); } #endregion } public class Consumer { public void DoSomething() { using (new UnitOfWorkScope<MyObjectContext>()) { } } } } Compiler error is: Error 1 'Sandbox.UnitOfWorkScope<Sandbox.MyObjectContext>': type used in a using statement must be implicitly convertible to 'System.IDisposable' I implemented IDisposable on UnitOfWorkScope (and to see if that was the problem, also on MyObjectContext). What am I missing?

  • Unable to pass variable data

    - by JM4
    I am trying to use the following code to pass information to another site but it keeps giving me an error: Invalid Code: $a = $b->doIt("James",$_SESSION['JNum'],"Frank"); Valid Sample Code: $a = $b->doIt("James","123456","Frank"); In the first example, the page returns "number field is required". The second piece of sample code returns valid results. Do to the nature of this project though I need to pass the id number as they are stored in SESSION variables. What am I missing?

  • When does a MySQL Query actually execute in PHP?

    - by MJB
    This sounds like a really simple question, but I am new to PHP. If I have a statement like this: $r =& $db->query("insert into table (col1, col2) values (10, 20)"); Do I have to still execute it, or does it get executed when I reference it? I have another case where I have a select query, which seems logically to run only when I call fetchrow, but the code I am presented with (to fix) does not call execute or fetch.I would have expected it to, so I cannot tell if it is just that I don't get it, or that the missing execute statement is the problem. It also does not insert the record, but it does not throw an error I can find. Also, I am a little confused by the =& notation. I looked it up on google, and found a few mentions of it, but I am still not clear on it. Thanks.

  • In an asp.net, how to get a reference of a custom webcontrol from a usercontrol?

    - by AJ
    Hi I have a page which holds a custom webcontrol and a usercontrol. I need to reference of webcontrol in usercontrol class. So, I make the declaration of webcontrol as public in page class. But, when I do “this.Page.”, I don’t see the webcontrol listed in list provided by intellisense. Most probably, I am missing something. In an asp.net page, how to get a reference of a custom webcontrol from a usercontrol? Please advise. Thanks Pankaj

  • Easy way to add multiple existing .csproj to a Visual Studio Solution?

    - by Michael J Swart
    I've checked out a branch of C# code from source control. It contains maybe 50 projects in various folders. There's no existing .sln file to be found. I intended to create a blank solution to add existing solutions. The UI only lets me do this one project at a time. Is there something I'm missing? I'd like to specify a list of *.csproj files and somehow come up with a .sln file that contains all the projects.

  • STL Static-Const Member Definitions

    - by javery
    How does the following work? #include <limits> int main() { const int* const foo = &std::numeric_limits<int> ::digits; } I was under the impression that in order to take an address of a static const-ant member we had to physically define it in some translation unit in order to please the linker. That said, after looking at the preprocessed code for this TU, I couldn't find an external definition for the digits member (or any other relevant members). I tested this on two compilers (VC++ 10 and g++ 4.2.4) and got identical results (i.e., it works). Does the linker auto-magically link against an object file where this stuff is defined, or am I missing something obvious here?

  • How to use startMethodTracing APIs on Android?

    - by Rajorshi
    I have recently started working on an app which has both Java and native components. I am trying to generate trace information for both components using Debug.startMethodTracing("myapp") and Debug.startNativeTracing() alternately. However, both are behaving unexpectedly. When I use Debug.startMethodTracing("myapp"), I can see a file /sdcard/myapp.trace being created but it is always empty no matter how long I run my app. When I use Debug.startNativeTracing() and start the emulator with the -trace <tracename> switch, I see a message saying "Trace started", but when I try to run my app, the emulator crashes. Am I missing something obvious here? How do I debug this problem?

  • presenting modal views in a popover

    - by sengbsd
    Hi, Im trying to load a modal view from a view controller that is displayed in a popover. The modal view loads but the problem is that it transitions into the main view and not within the popover. Is it something Im missing? I thought simply initiating it from a vc within a popover would present the modal view within the same popover... The code is nothing special as bellow: - (IBAction)myButton{ ModalVC *controller = [[ModalVC alloc] initWithNibName:@"ModalVC" bundle:nil]; [self presentModalViewController:controller animated:YES]; [controller release]; }

  • How do I route watir through a proxy pragmatically?

    - by feydr
    I'm trying to route watir through a proxy pragmatically -- this means within the script I'd like to change my proxy dynamically before launching the browser. Here's what I've tried so far (and so far am failing): I'm running chrome and lucid lynx ubuntu. I chose TREX cause I thought watir might be making use of PROXY or something. I rewrote /usr/bin/google-chrome as: #!/bin/bash /opt/google/chrome/chrome --proxy-server="$TREX" $@ The reason I'm passing in the environment variable to proxy-server rather than http_proxy is because I never could get http_proxy to work as is anyways then I did a simple: require 'rubygems' require 'watir-webdriver' ENV['TREX'] = "XX.XX.XX.XX:YY" browser = Watir::Browser.new(:chrome) browser.goto("http://mysite.com") Anyways, what is happening here is that it is forwarding me to the login page of the proxy rather than just forwarding the request. What am I missing here? I feel like I'm pretty close.

  • Are there any Python reference counting/garbage collection gotchas when dealing with C code?

    - by Jason Baker
    Just for the sheer heck of it, I've decided to create a Scheme binding to libpython so you can embed Python in Scheme programs. I'm already able to call into Python's C API, but I haven't really thought about memory management. The way mzscheme's FFI works is that I can call a function, and if that function returns a pointer to a PyObject, then I can have it automatically increment the reference count. Then, I can register a finalizer that will decrement the reference count when the Scheme object gets garbage collected. I've looked at the documentation for reference counting, and don't see any problems with this at first glance (although it may be sub-optimal in some cases). Are there any gotchas I'm missing? Also, I'm having trouble making heads or tails of the cyclic garbage collector documentation. What things will I need to bear in mind here? In particular, how do I make Python aware that I have a reference to something so it doesn't collect it while I'm still using it?

  • Google's OpenID identifier is different depending on the "consumer" domain name. How to avoid potent

    - by JohnnyO
    I'm currently testing an OpenID implementation, and I'm noticing that Google sends a different identifier for different consuming host name / domain name, even for the same user. For example, Google sends a different identifier when the requesting site is localhost, compared to the identifier they send when the requesting site is 127.0.0.1 for the same user. Note: I haven't actually tested this using public domain names, but I can't see why the behavior would be any different. My concern with Google's behavior is that if we ever choose to change our website domain name in the future, then users will no longer be able to log in to the website using Google's OpenId as the identity provider. This seems to be a big problem. Am I missing something, or are all OpenID consuming sites faced with this potential problem? I've also tested this with MyOpenId, but the identifier that MyOpenId creates is fixed, so this wouldn't be a problem with them. Thanks.

  • Losing DateTimeOffset precision when using C#

    - by Darvis Lombardo
    I have a SQL Server table with a CreatedDate field of type DateTimeOffset(2). A sample value which is in the table is 2010-03-01 15:18:58.57 -05:00 As an example, from within C# I retrieve this value like so: var cmd = new SqlCommand("SELECT CreatedDate FROM Entities WHERE EntityID = 2", cn); var da = new SqlDataAdapter(cmd); DataTable dt =new DataTable(); da.Fill(dt); And I look at the value: MessageBox.Show(dt.Rows[0][0].ToString()); The result is 2010-03-01 15:18:58 -05:00, which is missing the .57 that is stored in the database. If I look at dt.Rows[0][0] in the Watch window, I also do not see the .57, so it appears it has been truncated. Can someone shed some light on this? I need to use the date to match up with other records in the database and the .57 is needed. Thanks! Darvis

  • Ant - using vssadd to add multiple file

    - by mamendex
    Hi, I'm trying to use vssadd task to add a tree of source files to a recent created project on VSS. But it happens to be adding only the folder tree, all files missing. <vsscp vsspath="$/DEV/APL_${version}" ssdir="${vssapl}" serverPath="${vsssvr}"/> The vssadd task displays the name of the folders it's creating: ... (vssadd) $/DEV/APL_0.0.10c/src/domain: (vssadd) $/DEV/APL_0.0.10c/src/mbeans: (vssadd) $/DEV/APL_0.0.10c/src/service: ... The script runs successfully but the files never get in the repository. Trying to use wilcards are no good, the task says it found no matching files and ss returns with a code of 100: <vssadd ssdir="${vssapl}" localPath="C:\Workspace\APL_Build*.*" recursive="true" serverPath="${vsssvr}" comment="Build ${versao} at ${to.timestamp}"/ I've noticed that vssadd does not accept fileset tag either, so I'm kind of lost here. Any tips? tks
