  • error on connecting to the server : socket io is not defined

    - by max
    i know there's been couple of question about the same problem , i've already check them . i have very simple node.js chat app i have a server running on 8000 port and it works fine my client pages are html , they are running on apache and i'm using socket.io to connect them to the server and it works fine on the local host but when i upload the app on the server i keep on getting this error in the firebug io is not defined var socket = io.connect('http://atenak.com:8000/'); or sometimes it doesn't show that but when i try to broadcast message from cliend i get this error : socket is undefined socket.emit('msg', { data: msg , user:'max' }); the only difference is i've changed the localhost with atenak.com ! here is my html code var socket = io.connect('http://atenak.com:8000/'); var user = 'jack'; socket.on('newmsg', function (data) { if(data.user == user ) { $('#container').html(data.data); } }); function brodcast(){ var msg = $('#fild').val(); socket.emit('msg', { data: msg , user:'max' }); } </script> </head> <body> <div id="container"> </div> <input id="fild" type="text"> <input name="" type="button" onClick="brodcast();"> </body> i have included the sockt.io.js and server is running ok which means socket.io is installed on the server here is the live page http://atenak.com/client.html

  • Dragging a copy of all selected elements from a select box--possible?

    - by Sean
    I have a picklist web interface: a pair of select elements with a pair of buttons (a left-pointing arrow and a right-pointing arrow) between them. Users can move items between the two columns by, eg, selecting one of options in the left column and clicking on the right-pointing arrow. Now I have an enhancement request: someone wants to be able to drag-and-drop items between the two columns instead of clicking a button. The problem with my initial two-select-box setup is that as soon as I click one of the highlighted options to initiate a drag, all of the other selected options are deselected. Using jQuery, I've attached mousedown event handlers to both the select boxes and each individual option that just call preventDefault() on the event object, but this isn't sufficient. On Firefox 3 the clicked-on option loses focus immediately, but all other options are still deseleted, and on IE6 (which I regrettably still have to support) it makes no difference at all. So I thought I could maybe create a reasonable facsimile of a select box using list elements or divs or something. I can create something reasonable-looking that works on Firefox, but on IE6, if I shift-click on an element of my pseudo-select object (in order to select a range of options), IE selects all of the text between where I click and the last place I clicked. Again, I've attached preventDefault-ing mousedown, mouseup, and click handlers to all of the elements involved, but it doesn't help. I've even tried overlaying transparent divs over both my original select boxes and my pseudo-select objects, thinking to intercept mouse clicks and manage the selections manually, but I can't make it work on IE. If I use a select box, I can't prevent clicks from changing the selection, and if I use text that just looks like a select element, I can't prevent it from selecting a range of text on a shift-click. Is there some general solution, or am I just out of luck?

  • How to use HSQLDB in Oracle query syntax mode?

    - by Jan Algermissen
    I am trying to use HSQLDB as an embedded database in a spring application (for testing). As the target production database is Oracle, I would like to use HSQLDBs Oracle syntax mode feature. In the Spring config I use <jdbc:embedded-database type="HSQL" id="dataSource"> </jdbc:embedded-database> <jdbc:initialize-database data-source="dataSource" enabled="true"> <jdbc:script location="classpath:schema.sql"/> </jdbc:initialize-database> And in schema.sql at the top I wrote: SET DATABASE SQL SYNTAX ORA TRUE; However, when running my test, I get the following error: java.sql.SQLException: Unexpected token: DATABASE in statement [SET DATABASE SQL SYNTAX ORA TRUE] Is this a syntax error or a permissions error or something entirely different? Thanks - also for any pointers that might lead to the answer. Given that HSQL is the Spring default for jdbc:embedded-database and given the target is Oracle, this scenario should actually be very common. However, I found nothing on the Web even touching the issue.

  • Button style in AlertDialogs

    - by Steve H
    Does anyone know how to override the default style for AlertDialog buttons? I've looked through the Android source for themes and styles and experimented with different things but I haven't been able to find a way that works. What I've got below works for changing the backgrounds, but doesn't do anything with the buttons. myTheme is applied to the whole <application> via the manifest. (Some other items were deleted for clarity, but they only relate to the title bar.) <style name="myTheme" parent="android:Theme"> <item name="android:buttonStyle">@style/customButtonStyle</item> <item name="android:alertDialogStyle">@style/dialogAlertTheme</item> </style> <style name="dialogAlertTheme" parent="@android:style/Theme.Dialog.Alert"> <item name="android:fullDark">@drawable/dialog_loading_background</item> <item name="android:topDark">@drawable/dialog_alert_top</item> <item name="android:centerDark">@drawable/dialog_alert_center</item> <item name="android:bottomDark">@drawable/dialog_alert_bottom</item> <!-- this last line makes no difference to the buttons --> <item name="android:buttonStyle">@style/customButtonStyle</item> </style> Any ideas?

  • How can I create a new Person object correctly in Javascript?

    - by TimDog
    I'm still struggling with this concept. I have two different Person objects, very simply: ;Person1 = (function() { function P (fname, lname) { P.FirstName = fname; P.LastName = lname; return P; } P.FirstName = ''; P.LastName = ''; var prName = 'private'; P.showPrivate = function() { alert(prName); }; return P; })(); ;Person2 = (function() { var prName = 'private'; this.FirstName = ''; this.LastName = ''; this.showPrivate = function() { alert(prName); }; return function(fname, lname) { this.FirstName = fname; this.LastName = lname; } })(); And let's say I invoke them like this: var s = new Array(); //Person1 s.push(new Person1("sal", "smith")); s.push(new Person1("bill", "wonk")); alert(s[0].FirstName); alert(s[1].FirstName); s[1].showPrivate(); //Person2 s.push(new Person2("sal", "smith")); s.push(new Person2("bill", "wonk")); alert(s[2].FirstName); alert(s[3].FirstName); s[3].showPrivate(); The Person1 set alerts "bill" twice, then alerts "private" once -- so it recognizes the showPrivate function, but the local FirstName variable gets overwritten. The second Person2 set alerts "sal", then "bill", but it fails when the showPrivate function is called. The new keyword here works as I'd expect, but showPrivate (which I thought was a publicly exposed function within the closure) is apparently not public. I want to get my object to have distinct copies of all local variables and also expose public methods -- I've been studying closures quite a bit, but I'm still confused on this one. Thanks for your help.

  • Show image from clipboard to defalut imageviewer of windows using c#.net

    - by Rajesh Rolen- DotNet Developer
    I am using below function to make a image of current form and set it in clipboard Image bit = new Bitmap(this.Width, this.Height); Graphics gs = Graphics.FromImage(bit); gs.CopyFromScreen(this.Location, new Point(0, 0), bit.Size); Guid guid = System.Guid.NewGuid(); string FileName = guid.ToString(); //Copy that image in the clipbaord. Image imgToCopy = Image.FromFile(Path.Combine(Environment.CurrentDirectory, FileName + ".jpg")); Clipboard.SetImage(imgToCopy); Now my image is in clipboard and i am able to show it in picturebox on other form using below code : mypicturebox.Image = Clipboard.GetImage(); Now the the problem is that i want to show it in default imageviewer of that system. so for that i think using "System.Diagnostics.Process.Start" we can do that.. but i dont know, how to find default imageviewer and how to set clipboard's image in that ... please help me out... if i find solution than thats good otherwise i am thinking to save that file from clipboard to harddisk and then view it in window's default imageviewer... please help me to resolve my problem.. i am using c#.net

  • How do I forward `<Ctrl>-<Tab>` in Konsole?

    - by M. Tibbits
    I want to use intelligent tabbing in Emacs in C++ mode, but I also want to be able to insert a tab character when necessary. From other posts, I gather that the easiest way is to bind <Ctrl>-<Tab> to indent. However, it appears that Konsole in KUbuntu won't forward the <Ctrl>? My current .emacs file contains: (defun my-c-mode-common-hook () (setq c++-tab-always-indent t) (setq tab-width 4) (setq indent-tabs-mode t) ) (add-hook 'c-mode-common-hook 'my-c-mode-common-hook) (global-set-key [C-tab] 'self-insert-command) So I believe that this will bind <Ctrl>-<Tab> to inserting a tab character. However, when I run: <Ctrl>-h k <Ctrl>-<Tab> Emacs only reports that I pressed the tab key. Is there some option to Konsole (which I have searched through to no avail) or global preferences in KUbuntu that I need to set so that the <Ctrl>- is also forwarded? (It certainly forwards all of the other <Ctrl>-blah commands.)

  • Can I make any ASP.NET/HTML element into form-data that posts back to the server?

    - by Giffyguy
    I am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value. The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well. I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?

  • Automated Oracle Schema Migration Tool

    - by Dave Jarvis
    What are some tools (commercial or OSS) that provide a GUI-based mechanism for creating schema upgrade scripts? To be clear, here are the tool responsibilities: Obtain connection to recent schema version (called "source"). Obtain connection to previous schema version (called "target"). Compare all schema objects between source and target. Create a script to make the target schema equivalent to the source schema ("upgrade script"). Create a rollback script to revert the source schema, used if the upgrade script fails (at any point). Create individual files for schema objects. The software must: Use ALTER TABLE instead of DROP and CREATE for renamed columns. Work with Oracle 10g or greater. Create scripts that can be batch executed (via command-line). Trivial installation process. (Bonus) Create scripts that can be executed with SQL*Plus. Here are some examples (from StackOverflow, ServerFault, and Google searches): Change Manager Oracle SQL Developer Software that does not meet the criteria, or cannot be evaluated, includes: TOAD PL/SQL Developer - Invalid SQL*Plus statements. Does not produce ALTER statements. SQL Fairy - No installer. Complex installation process. Poorly documented. DBDiff - Crippled data set evaluation, poor customer support. OrbitDB - Crippled data set evaluation. SchemaCrawler - No easily identifiable download version for Oracle databases. SQL Compare - SQL Server, not Oracle. LiquiBase - Requires changing the development process. No installer. Manually edit config files. Does not recognize its own baseUrl parameter. The only acceptable crippling of the evaluation version is by time. Crippling by restricting the number of tables and views hides possible bugs that are only visible in the software during the attempt to migrate hundreds of tables and views.

  • R:how to get grep to return the match, rather than the whole string

    - by Mike Dewar
    Hi, I have what is probably a really dumb grep in R question. Apologies, because this seems like it should be so easy - I'm obviously just missing something. I have a vector of strings, let's call it alice. Some of alice is printed out below: T.8EFF.SP.OT1.D5.VSVOVA#4 T.8EFF.SP.OT1.D6.LISOVA#1 T.8EFF.SP.OT1.D6.LISOVA#2 T.8EFF.SP.OT1.D6.LISOVA#3 T.8EFF.SP.OT1.D6.VSVOVA#4 T.8EFF.SP.OT1.D8.VSVOVA#3 T.8EFF.SP.OT1.D8.VSVOVA#4 T.8MEM.SP#1 T.8MEM.SP#3 T.8MEM.SP.OT1.D106.VSVOVA#2 T.8MEM.SP.OT1.D45.LISOVA#1 T.8MEM.SP.OT1.D45.LISOVA#3 I'd like grep to give me the number after the D that appears in some of these strings, conditional on the string containing "LIS" and an empty string or something otherwise. I was hoping that grep would return me the value of a capturing group rather than the whole string. Here's my R-flavoured regexp: pattern <- (?<=\\.D)([0-9]+)(?=.LIS) nothing too complicated. But in order to get what I'm after, rather than just using grep(pattern, alice, value = TRUE, perl = TRUE) I'm doing the following, which seems bad: reg.out <- regexpr( "(?<=\\.D)[0-9]+(?=.LIS)", alice, perl=TRUE ) substr(alice,reg.out,reg.out + attr(reg.out,"match.length")-1) Looking at it now it doesn't seem too ugly, but the amount of messing about it's taken to get this utterly trivial thing working has been embarrassing. Anyone any pointers about how to go about this properly? Bonus marks for pointing me to a webpage that explains the difference between whatever I access with $,@ and attr.

  • How to properly use references with variadic templates

    - by Hippicoder
    I have something like the following code: template<typename T1, typename T2, typename T3> void inc(T1& t1, T2& t2, T3& t3) { ++t1; ++t2; ++t3; } template<typename T1, typename T2> void inc(T1& t1, T2& t2) { ++t1; ++t2; } template<typename T1> void inc(T1& t1) { ++t1; } I'd like to reimplement it using the proposed variadic templates from the upcoming standard. However all the examples I've seen so far online seem to be printf like examples, the difference here seems to be the use of references. I've come up with the following: template<typename T> void inc(T&& t) { ++t; } template<typename T,typename ... Args> void inc(T&& t, Args&& ... args) { ++t inc(args...); } What I'd like to know is: Should I be using r-values instead of references? Possible hints or clues as to how to accomplish what I want correctly. What guarantees does the new proposed standard provide wrt the issue of the recursive function calls, is there some indication that the above variadic version will be as optimal as the original? (should I add inline or some-such?)

  • db:migrate creates sequences but doesn't alter table?

    - by RewbieNewbie
    Hello, I have a migration that creates a postres sequence for auto incrementing a primary identifier, and then executes a statement for altering the column and specifying the default value: execute 'CREATE SEQUENCE "ServiceAvailability_ID_seq";' execute <<-SQL ALTER TABLE "ServiceAvailability" ALTER COLUMN "ID" set DEFAULT NEXTVAL('ServiceAvailability_ID_seq'); SQL If I run db:migrate everything seems to work, in that no errors are returned, however, if I run the rails application I get: Mnull value in column "ID" violates not-null constraint I have discovered by executing the sql statement in the migration manually, that this error is because the alter statement isn't working, or isn't being executed. If I manually execute the following statement: CREATE SEQUENCE "ServiceAvailability_ID_seq; I get: error : ERROR: relation "serviceavailability_id_seq" already exists Which means the migration successfully created the sequence! However, if I manually run: ALTER TABLE "ServiceProvider" ALTER COLUMN "ID" set DEFAULT NEXTVAL('ServiceProvider_ID_seq'); SQL It runs successfully and creates the default NEXTVAL. So the question is, why is the migration file creating the sequence with the first execute statement, but not altering the table in the second execute? (Remembering, no errors are output on running db:migrate) Thank you and apologies for tl:dr

  • How to cache an HTTP POST response?

    - by KARASZI István
    I would like to create a cacheable HTTP response for a POST request. My actual implementation responses the following for the POST request: HTTP/1.1 201 Created Expires: Sat, 03 Oct 2020 15:33:00 GMT Cache-Control: private,max-age=315360000,no-transform Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Content-Length: 9 ETag: 2120507660800737950 Last-Modified: Wed, 06 Oct 2010 15:33:00 GMT ......... But it looks like that the browsers (Safari, Firefox tested) are not cacheing the response. In the HTTP RFC the corresponding part says: Responses to this method are not cacheable, unless the response includes appropriate Cache-Control or Expires header fields. However, the 303 (See Other) response can be used to direct the user agent to retrieve a cacheable resource. So I think it should be cached. I know I could set a session variable and set a cookie and do a 303 redirect, but I want to cache the response of the POST request. Is there any way to do this? P.S.: I've started with a simple 200 OK, so it does not work. Thanks,

  • What should a self-taught programmer with no degree learn/read?

    - by sjbotha
    I am a self-taught programmer and I do do not have any degrees. I started pretty young and I've got about 7 years of actual programming work experience. I believe I'm a pretty good programmer, but I admit that I have not played much with algorithms or delved into any really low-level aspects of programming such as how compilers work. I have worked with other programmers with and without degrees. Some were good and some not; having a degree didn't seem to make any difference as to which pot they fell into. Since then I've come to realize that it does depend on the school where the degree is obtained. Some people suggest that you really should get a degree; that there are things you'll learn in the process that you won't learn in the real world. Of course there is personal growth and discipline learned from completing a task of that magnitude, but let's just concentrate on the technical knowledge. What would I have been taught in a GOOD CS course that would aid me today and what can I read to fill the gap? I've heard the book "Algorithms" mentioned and I plan on reading that. What other books would you recommend? Edit: Clarification on 'actual work experience': Have worked for 2 small companies on teams with fewer than 5 people. About 2 years experience with Perl, Python, PHP, C, C++. About 5 years experience in Java, Applets, RMI, T-SQL, PL/SQL, VB6. 7 years experience in HTML, Javascript, bash, SQL. Most recently in Java designed and helped build an N-tier Java app with web frontend and RMI.

  • IIS 7.5 can't access file from managed code

    - by Bob
    I am working on a project that is click-once deployed from an IIS 7.5 web server. After installing the parent application (i.e. setting up the IIS site) I am able to hit the url for the click-once app's config file from a remote box. HOWEVER, when I attempt to do the same thing from my app (and the stub app below), I get a 401 Unauthorized. What is the difference between hitting the URL from IE, and from a .NET app? The file and directory itself have full control granted to everyone on the webserver at the moment, and I am an admin on the box. We are using Windows Authentication with NTLM only. Thanks, -Bob Here is the stub app that produces the 401 - Unauthorized when on the doc.Load() line. I can hit the same URL successfully from IE and open the file... static void Main(string[] args) { Console.WriteLine("Config Test"); string filename = "http://dev-rs/myClient/myClickOnce/myApp.config.xml"; Console.WriteLine(filename); XmlDocument doc = new XmlDocument(); doc.Load(filename); Console.WriteLine("Loaded"); Console.WriteLine("Inner Text : " + doc.InnerText); }

  • How to add validation errors in the validation collection asp.net mvc?

    - by johndoe
    Inside my controller's action I have the following code: public ActionResult GridAction(string id) { if (String.IsNullOrEmpty(id)) { // add errors to the errors collection and then return the view saying that you cannot select the dropdownlist value with the "Please Select" option } return View(); UPDATE: if (String.IsNullOrEmpty(id)) { // add error ModelState.AddModelError("GridActionDropDownList", "Please select an option"); return RedirectToAction("Orders"); } } UPDATE 2: Here is my updated code: @Html.DropDownListFor(x => x.SelectedGridAction, Model.GridActions,"Please Select") @Html.ValidationMessageFor(x => x.SelectedGridAction) The Model looks like the following: public class MyInvoicesViewModel { private List<SelectListItem> _gridActions; public int CurrentGridAction { get; set; } [Required(ErrorMessage = "Please select an option")] public string SelectedGridAction { get; set; } public List<SelectListItem> GridActions { get { _gridActions = new List<SelectListItem>(); _gridActions.Add(new SelectListItem() { Text = "Export to Excel", Value = "1"}); return _gridActions; } } } And here is my controller action: public ActionResult GridAction(string id) { if (String.IsNullOrEmpty(id)) { // add error ModelState.AddModelError("SelectedGridAction", "Please select an option"); return RedirectToAction("Orders"); } return View(); } Nothing happens! I am totally lost on this one! UPDATE 3: I am now using the following code but still the validation is not firing: public ActionResult GridAction(string id) { var myViewModel= new MyViewModel(); myViewModel.SelectedGridAction = id; // id is passed as null if (!ModelState.IsValid) { return View("Orders"); }

  • For the professional programmers - do you still write code for fun at home ? [closed]

    - by Led
    Possible Duplicate: Do you ever code just for fun? I've been working as a 'professional' coder for about 11 years. (I've just turned 33.) When I talk to my collegues, I find that most of them actually don't program any more in their spare time - 8 (or 10 :)) hours a day at their job is enough for them. A difference between me and them might be that I was always programming for fun (demoscene stuff etc.) which is why I got into the field, while most of them picked up programming later on (at university or whatever). When I get home my head is always full of ideas, so usually I have a hobby-project going on. Is it weird to spend 8 hours a day programming, and then get home, have dinner, and do some more ? For me the reasons are just - ideas : trying stuff - wanting to develop something all by myself, so when it's finished I can claim it as my own victory How about you ? And if you do, do you have other reasons to do so ? Edit: And if you've got sparetime projects, it might be fun to tell us a bit about it :) Spamming a link to your site/hobbyproject won't be frowned upon here ! Edit2: Vote for this if you want to encourage companies to make monitors that'll give you a nice tan ! ;-)

  • Confused about definition of a 'median' when constructing a kd-Tree

    - by user352636
    Hi there. Im trying to build a kd-tree for searching through a set of points, but am getting confused about the use of 'median' in the wikipedia article. For ease of use, the wikipedia article states the pseudo-code of kd-tree construction as: function kdtree (list of points pointList, int depth) { if pointList is empty return nil; else { // Select axis based on depth so that axis cycles through all valid values var int axis := depth mod k; // Sort point list and choose median as pivot element select median by axis from pointList; // Create node and construct subtrees var tree_node node; node.location := median; node.leftChild := kdtree(points in pointList before median, depth+1); node.rightChild := kdtree(points in pointList after median, depth+1); return node; } } I'm getting confused about the "select median..." line, simply because I'm not quite sure what is the 'right' way to apply a median here. As far as I know, the median of an odd-sized (sorted) list of numbers is the middle element (aka, for a list of 5 things, element number 3, or index 2 in a standard zero-based array), and the median of an even-sized array is the sum of the two 'middle' elements divided by two (aka, for a list of 6 things, the median is the sum of elements 3 and 4 - or 2 and 3, if zero-indexed - divided by 2.). However, surely that definition does not work here as we are working with a distinct set of points? How then does one choose the correct median for an even-sized list of numbers, especially for a length 2 list? I appreciate any and all help, thanks! -Stephen

  • TeamCity + HG. Only pull (push?) passing builds

    - by ColoradoMatt
    Feels like with the popularity of continuous integration this one should be a piece of cake but I am stumped. I am setting up TeamCity with HG. I want to be able to push changesets up to a repository that TeamCity watches and runs builds on changes. That's easy. Next, if a build passes, I want that changeset to be pulled into a "clean" repository... one that contains only passing changesets. Should be easy but... TeamCity 6 supports multiple build steps and if any step fails, the rest don't run. My thought was to put a build step at the end that does a pull (or optionally a push?) to get the passing changeset into the clean repository. I am trying to use PsExec to run hg on the box with the repositories. If I try to run just a plain 'hg pull' it can't find the hg.exe even though it is set in the path and I have used the -w flag. I have tried putting a .bat file in the clean repository that takes a revision parameter and it works fine... locally. When I try to run the .bat file remotely (using PsExec) it runs everything fine but it tries to run it on the build agent. Even if I set the -w argument it runs the .bat file there but tries to run the contents on the build agent box. Am I just WAY off in my approach? Seems like this is a pretty obvious thing to do so either my Google skills are waning or no one thinks this is worthy of writing about. Either way, I am stuck in SVN land trying to get out so I would appreciate some help!

  • Criteria API - How to get records based on collection count?

    - by Cosmo
    Hello Guys! I have a Question class in ActiveRecord with following fields: [ActiveRecord("`Question`")] public class Question : ObcykaniDb<Question> { private long id; private IList<Question> relatedQuestions; [PrimaryKey("`Id`")] private long Id { get { return this.id; } set { this.id = value; } } [HasAndBelongsToMany(typeof(Question), ColumnRef = "ChildId", ColumnKey = "ParentId", Table = "RelatedQuestion")] private IList<Question> RelatedQuestions { get { return this.relatedQuestions; } set { this.relatedQuestions = value; } } } How do I write a DetachedCriteria query to get all Questions that have at least 5 related questions (count) in the RelatedQuestions collection? For now this gives me strange results: DetachedCriteria dCriteria = DetachedCriteria.For<Question>() .CreateCriteria("RelatedQuestions") .SetProjection(Projections.Count("Id")) .Add(Restrictions.EqProperty(Projections.Id(), "alias.Id")); DetachedCriteria dc = DetachedCriteria.For<Question>("alias").Add(Subqueries.Le(5, dCriteria)); IList<Question> results = Question.FindAll(dc); Any ideas what I'm doing wrong?

  • Uncaught exception while using xdebug

    - by rich97
    I'm not too great with xdebug so forgive me if this is a stupid question. But I installed it on a separate machine and it performed some magic for me like formating my var_dump() output and catching any uncaught exceptions. It also fails to format the stack traces, outputting plain text which is extremely hard to read. As I am learning the Lithium PHP Framework I am required to use php5.3, on my other machine I compiled from the source but on this machine I'm using the precompiled packages from dotdeb.org. As far as I can tell the only difference is that this is a slightly newer version of php and it comes with the Suhosin patch. The other odd thing is that the xdebug functions such as xdebug_var_dump() work, aside from poor formatting. This is an Ubuntu machine, so I don't know if it could be anything to do with the dotdep packages, but I have installed xdebug through pecl, the downloadable tarball and from the SVN repository. But to no avail. You can see my php.ini and output of php -i in the following gist. I copied php.ini from /etc/php5/apache2/php.ini over to /etc/php5/cli/php.ini so php -i should reflect my apache setup. http://gist.github.com/391675 Any help is appreciated. Rich

  • PHP Session data not being saved

    - by Crackerjack
    I have one of those "I swear I didn't touch the server" situations. I honestly didn't touch any of the php scripts. The problem I am having is that php data is not being saved across different pages or page refreshes. I know a new session is being created correctly because I can set a session variable (e.g. $_SESSION['foo'] = "foo" and print it back out on the same page just fine. But when I try to use that same variable on another page it is not set! Is there any php functions or information I can use on my hosts server to see what is going on? Here is an example script that does not work on my hosts' server as of right now: <?php session_start(); if(isset($_SESSION['views'])) $_SESSION['views'] = $_SESSION['views']+ 1; else $_SESSION['views'] = 1; echo "views = ". $_SESSION['views']; echo '<p><a href="page1.php">Refresh</a></p>'; ?> The 'views' variable never gets incremented after doing a page refresh. I'm thinking this is a problem on their side, but I wanted to make sure I'm not a complete idiot first. Here is the phpinfo() for my hosts' server (PHP Version 4.4.7):

  • Stringing multiple ShellExecute calls

    - by IVlad
    Consider the following code and its executable - runner.exe: #include <iostream> #include <string> #include <windows.h> using namespace std; int main(int argc, char *argv[]) { SHELLEXECUTEINFO shExecInfo; shExecInfo.cbSize = sizeof(SHELLEXECUTEINFO); shExecInfo.fMask = NULL; shExecInfo.hwnd = NULL; shExecInfo.lpVerb = "open"; shExecInfo.lpFile = argv[1]; string Params = ""; for ( int i = 2; i < argc; ++i ) Params += argv[i] + ' '; shExecInfo.lpParameters = Params.c_str(); shExecInfo.lpDirectory = NULL; shExecInfo.nShow = SW_SHOWNORMAL; shExecInfo.hInstApp = NULL; ShellExecuteEx(&shExecInfo); return 0; } These two batch files both do what they're supposed to, which is run notepad.exe and run notepad.exe and tell it to try to open test.txt: 1. runner.exe notepad.exe 2. runner.exe notepad.exe test.txt Now, consider this batch file: 3. runner.exe runner.exe notepad.exe This one should run runner.exe and send notepad.exe as one of its command line arguments, shouldn't it? Then, that second instance of runner.exe should run notepad.exe - which doesn't happen. If I print the argc argument, it's 14 for the second instance of runner.exe, and they are all weird stuff like Files\Microsoft, SQL, Files\Common and so on. I can't figure out why this happens. I want to be able to string as many runner.exe calls using command line arguments as possible, or at least 2. How can I do that? I am using Windows 7 if that makes a difference.
