• Why would the IE Developer Toolbar claim a style is applied, yet that supposed fact is not reflected

  - by Deane

  I have a situation where IE7 is simply not applying styles, even though it claims it is. I have an element on my page. In the CSS, I have defined a rule that should apply "display: none" to it, so it should not be displayed. It's still displaying. I downloaded the IE Developer Toolbar, and found the element in the DOM selector. I right-clicked and selected "Applied Styles." Right there, IE claims that it is applying my "display: none" rule. In fact, the "Applied Styles" dialog confirms everything I think I know about my CSS and how it should be applied. Yet the element remains. Now, I'm not asking anyone to debug my CSS here. I'm asking, if the IE Developer Toolbar claims/confirms this element should be gone, but it's still there...what does that mean, exactly? Since the Toolbar is on my side, I think my CSS is fine. Is there some IE7 bug I'm not considering? Edit: One thing that might be relevant: the LINK elements that load the stylesheets are applied to the page in Javascript, via "document.write". I'm starting to suspect that has something to do with it.

• How do you export or release a Mac OS X program made in Xcode? Program does not load on other comput

  - by SolidSnake4444

  I made a program in Xcode, being a simple calculator that takes a first number, and a second number, and then either adds,subtracts,multiplies, or divides depending on the radio button. I build and run and the program comes up and works fine. When I went to show my friends on their macs, when you double click on the program the program pops in the tray for like .05 seconds and then disappears and we never can actually run the program. It still works perfect however on my computer. What am I doing wrong? How can I take the program I made, and run it on different macs? I have the release set to 10.5 but the active SDK to 10.6. It runs in both 10.5 and 10.6 simulators. One friend has 10.6.3 like me and the other has 10.5.x(cant remember the last part). To get the app, I changed from debug to release and set active SDK to 10.5. Then in the release folder I found the app and sent that over iChat. I feel this will be a problem in the future if I ever make a legit application to distribute. Thank you!

• Ruby Alias and module_function

  - by Jesse J

  I'm trying to debug someone else's code and having trouble figuring out what's wrong. When I run rake, one of the errors I get is: 2) Error: test_math(TestRubyUnits): NoMethodError: undefined method `unit_sin' for CMath:Module /home/user/ruby-units/lib/ruby_units/math.rb:21:in `sin' This is the function that calls the method: assert_equal Math.sin(pi), Math.sin("180 deg".unit) And this is what the class looks like: module Math alias unit_sin sin def sin(n) Unit === n ? unit_sin(n.to('radian').scalar) : unit_sin(n) end alias unit_cos cos def cos(n) Unit === n ? unit_cos(n.to('radian').scalar) : unit_cos(n) end ... module_function :unit_sin module_function :sin module_function :unit_cos module_function :cos ... end (The ellipsis means "more of the same"). As far as I can see, this is valid Ruby code. Is there something I'm missing here that's causing the error, or could the error be coming from something else? Update: I'm wondering if the problem has to do with namespaces. This code is attempting to extend CMath, so perhaps the alias and/or module_function isn't actually getting into CMath, or something like that....

• List iterator not dereferencable?

  - by Roderick

  Hi All I get the error "list iterator not dereferencable" when using the following code: bool done = false; while (!_list_of_messages.empty() && !done) { // request the next message to create a frame // DEBUG ERROR WHEN NEXT LINE IS EXECUTED: Counted_message_reader reader = *(_list_of_messages.begin()); if (reader.has_more_data()) { _list_of_frames.push_back(new Dlp_data_frame(reader, _send_compressed_frames)); done = true; } else { _list_of_messages.pop_front(); } } (The line beginning with "Counted_message_reader..." is the one giving the problem) Note that the error doesn't always occur but seemingly at random times (usually when there's lots of buffered data). _list_of_messages is declared as follows: std::list<Counted_message_reader> _list_of_messages; In the surrounding code we could do pop_front, push_front and size, empty or end checks on _list_of_messages but no erase calls. I've studied the STL documentation and can't see any glaring problems. Is there something wrong with the above code or do I have a memory leak somewhere? Thanks! Appreciated!

• NSTableView don't display data

  - by Tomas Svoboda

  HI, I have data in NSMutableArray and I want to display it in NSTableView, but only the number of cols has changed. This use of NSTableView is based on tutorial: http://www.youtube.com/watch?v=5teN5pMf-rs FinalImageBrowser is IBOutlet to NSTableView @implementation AppController NSMutableArray *listData; - (void)awakeFromNib { [FinalImageBrowser setDataSource:self]; } - (IBAction)StartReconstruction:(id)sender { NSMutableArray *ArrayOfFinals = [[NSMutableArray alloc] init]; //Array of list with final images NSString *FinalPicture; NSString *PicNum; int FromLine = [TextFieldFrom intValue]; //read number of start line int ToLine = [TextFieldTo intValue]; //read number of finish line int RecLine; for (RecLine = FromLine; RecLine < ToLine; RecLine++) //reconstruct from line to line { Start(RecLine); //start reconstruction //Create path of final image FinalPicture = @"FIN/final"; PicNum = [NSString stringWithFormat: @"%d", RecLine]; FinalPicture = [FinalPicture stringByAppendingString:PicNum]; FinalPicture = [FinalPicture stringByAppendingString:@".bmp"]; [ArrayOfFinals addObject:FinalPicture]; // add path to array } listData = [[NSMutableArray alloc] init]; [listData autorelease]; [listData addObjectsFromArray:ArrayOfFinals]; [FinalImageBrowser reloadData]; NSBeep(); //make some noise NSImage *fin = [[NSImage alloc] initWithContentsOfFile:FinalPicture]; [FinalImage setImage:fin]; } - (int)numberOfRowsInTableView:(NSTableView *)tv { return [listData count]; } - (id)tableView:(NSTableView *)tv objectValueFromTableColumn:(NSTableColumn *)tableColumn row:(int)row { return (NSString *)[listData objectAtIndex:row]; } @end when the StartReconstruction end the number of cols have changed right, but they're empty. When I debug app, items in listData is rigth. Thanks

• Visual Studio 2010 / ASP.NET MVC 2 / Publish

  - by SevenCentral

  I just did a clean install on Windows 7 x64 Professional with the final release of Visual Studio 2010 Premium. In order to duplicate what I'm experiencing do the following in: Create a new ASP.NET MVC 2 Web Application Right click the project and select Properties On the Web tab, select "Use Local IIS Web Server" Click on Create Virtual Directory Save all Unload the project Edit the project file Change MvcBuildViews to true Save all Reload project Right click the project and select Publish Choose the file system publish method Enter a target location Choose Delete all existing files Select Publish Right click the project Select Publish Each time I do the above I get the following errror: "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level..." The error originates from obj\debug\package\packagetmp\web.config, relative to the project directory. I can repeat this all day long with any MVC 2 project I've built. In order to fix this problem, I need to set MvcBuildViews to false in the project file. That's not really an option. This wasn't a problem in Visual Studio 2008 and it seems to be an issue with the way the Publish command stages files beneath the project directory. Can anyone else duplicate this error? Is this a bug or by design? Is there a fix, workaround, etc...? Thanks.

• Boost multi_index_container crash in release mode

  - by Zan Lynx

  I have a program that I just changed to using a boost::multi_index_container collection. After I did that and tested my code in debug mode, I was feeling pretty good about myself. However, then I compiled a release build with NDEBUG set, and the code crashed. Not immediately, but sometimes in single-threaded tests and often in multi-threaded tests. The segmentation faults happen deep inside boost insert and rotate functions related to the index updates and they are happening because a node has NULL left and right pointers. My code looks a bit like this: struct Implementation { typedef std::pair<uint32_t, uint32_t> update_pair_type; struct watch {}; struct update {}; typedef boost::multi_index_container< update_pair_type, boost::multi_index::indexed_by< boost::multi_index::ordered_unique< boost::multi_index::tag<watch>, boost::multi_index::member<update_pair_type, uint32_t, &update_pair_type::first> >, boost::multi_index::ordered_non_unique< boost::multi_index::tag<update>, boost::multi_index::member<update_pair_type, uint32_t, &update_pair_type::second> > > > update_map_type; typedef std::vector< update_pair_type > update_list_type; update_map_type update_map; update_map_type::iterator update_hint; void register_update(uint32_t watch, uint32_t update); void do_updates(uint32_t start, uint32_t end); }; void Implementation::register_update(uint32_t watch, uint32_t update) { update_pair_type new_pair( watch_offset, update_offset ); update_hint = update_map.insert(update_hint, new_pair); if( update_hint->second != update_offset ) { bool replaced _unused_ = update_map.replace(update_hint, new_pair); assert(replaced); } }

• Why are Facebook Likes Insisting on using Wrong Product Image...?

  - by Joan Kent

  Firstly, I'm not a web developer so please be patient. I have read the other posts but I think i have everything covered. My website http://www.joaniesgifts.co.uk includes the like button on the product pages. However, I've found that certain product pages are using the incorrect image when a user likes the page. For example - http://www.joaniesgifts.co.uk/terramundi-money-pots/terramundi-money-pot-holiday-fund I think this may have been down to an original incorrect setup which is now corrected. However, the problem remains... The only thing I have to go on :- if i use the facebook url linter (developers.facebook.com/tools/debug) on the above product page, I receive the following error :- Object at URL 'http://www.joaniesgifts.co.uk/terramundi-money-pot-holiday-fund' of type '213689662010141:product' is invalid because the domain 'www.joaniesgifts.co.uk' is not allowed for the application id '213689662010141' which owns the specified object type. If you are the owner of this application, you can verify your configured 'Site Domain' at developers.facebook.com/apps/213689662010141. (I have verified my site's domain) Everything else appears fine except it is also showing the wrong image!! However, under Raw Open Graph Document Information it has the correct link! If I then click graph api - graph.facebook.com/10150450766583352 it again shows the wrong image was linked! I've no idea what else to do - can you help me? Kind Regards, Joan PS Graph API shows the incorrect image after a scrape only minutes ago { "url": "http://www.joaniesgifts.co.uk/terramundi-money-pot-holiday-fund", "type": "website", "title": "Terramundi Money Pot - Holiday Fund", "image": [ { "url": "http://www.joaniesgifts.co.uk/index.php?route=product\u00252Fproduct\u00252Fcaptcha" } ], "updated_time": "2011-11-11T18:54:38+0000", "id": "10150450766583352" }

• heroku logs --ps run showign nothing

  - by Zarne Dravitzki

  I have two running apps on heroku staging and production. They are near identical enviornments. (Staging has extra configs IE RailsFootnotes, Bullet gem) When I run heroku logs --ps run --app jl-staging Returns as logs like 2012-08-30T01:30:42+00:00 heroku[run.1]: Starting process with command `bundle exec rake jewellover:warn_users` This log is a Task set to run with Heroku Schedular Free. Everything Works perfect but when I do the same with heroku logs --ps run --app jl-production There are no results. No heroku[run.1] process logs. Both environments have the same scheduled tasks, albeit at different times but none the less both run scheduled tasks at specified times. Is there something im missing about heroku[run.1] processes in production env? Does heroku only keep the -ps logs for a certain amount of time? It seems to show less activity than the normal logs. Maybe only show 24hrs worth of logs rather than Last 100 logs... I need to log and debug the [run.1] process from the production env... specifically the jewellover:warn_users task. any ideas?

• Javascript not registering/executing after button click

  - by rs

  I have a textbox which i convert to tinymce textbox using tinymce.js file. I'm trying to add a new script with database fields substituted based on selection made from dropdownlist to page using registerstartupscript. In page load protected sub page_load(byVal sender as object, byval e as EventArgs) handles me.load AddScriptToPage() if not page.ispostback() then session("fname") = nothing end if end sub Script Method Sub AddScriptToPage() dim _script = " c.onRenderMenu.add(function(c, m) { " & _ add_columns() & _ "}); " ClientScript.RegisterStartupScript(Me.GetType(), keyword,_script) End Sub function add_columns() as string dim ret_string = String.empty select case ddlList.selectedvalue case 1 sqlcommand = "xyz" case 2 sqlcommand = "xyz" case 3 //Load from excel sqlcommand = nothing end select if sqlcommand isnot nothing then executereader() while reader.read() ret_string = ret_string & reader("column") end while elseif session("fname") isnot nothing dt = getdatatable(session("fname").tostring()) //method that opens oledb connection and returns columns for each dr in dt.rows ret_string = ret_string & dr("column") next end if add_columns = ret_string end function When excel file is uploaded to server this event is called protected sub btnclick(byVal sender as object, byval e as EventArgs) if hasfile then 'i have custom properties set after control validation 'Upload file 'set session value with filepath session("fname") = filepath 'call js register event AddScriptToPage() end if end sub When i click upload button i'm calling AddScriptToPage, and debug it it hits AddScripttoPage event and executes it but it doesn't showup on page. It should show column names in tinymce editor but it doesn't. But when i click another button on the same page it shows (becos session has the filename). On Upload button click page flow: Page load - AddScriptToPage is executed (registers scripts with no columns) Then AddScriptToPage in btnclick event is executed (registers scripts with columns) Why is this script not getting registered even though it is executed on vb code on uploadclick event? And why does it show up after another button click and not original button click that calls this event?

• VS 2008 debugger: How does it decide what Cassini port to run a web service under?

  - by BDW

  I have a VS 2008 solution that includes a web site and a web service. I'm developing both at once, and it's helpful to be able to debug from one into the other. It occasionally can't find the web service. If I look in the web.config, I find the port number it's looking at is not the port number it auto-runs the service in when I use the debugger. For example, the web.config reference says something like: add key="mynamespace.mywebservice" value="http://localhost:55765/mywebservice.asmx" When I hover over the Cassini port icon, I find that the web service is running in port 55382 (or some other non-55765 port). No wonder it can't find it. Is there a way to enforce that the port number it runs under is the one specified in the web config? And if it's not using the web config port number to figure out where to run it... where does it decide? I know in VS2005, there was a way to specify the port number to use when debugging, but I can't find that anywhere in the web service project in VS 2008. This is really going to cause problems as more developers come on to this project - how can I fix it? Deleting and re-adding the web services to the project fixes it, but I'd literally have to do it a couple times a day, not an ideal solution.

• MySQL SELECT Statement not working when executed from PHP

  - by Andrew K

  Hello all, I have the following piece of code, executing a pretty simple MySQL query: $netnestquery = 'SELECT (`nested`+1) AS `nest` FROM `ipspace6` WHERE `id`<='.$adaddr.' AND `subnet`<='.$postmask.' AND `type`="net" AND `addr` NOT IN(SELECT `id` FROM `ipspace6` WHERE `addr`<'.$adaddr.' AND `type`="broadcast") ORDER BY `id`,`subnet` DESC LIMIT 1'; $netnestresults = mysql_query($netnestquery); $netnestrow = mysql_fetch_array($netnestresults); $nestlvl = $netnestrow['nest']; echo '<br> NESTQ: '.$netnestquery; Now, when I execute this in PHP, I get no results; an empty query. However, when I copy and paste the query echoed by my code (for debug purposes) into the mysql command line, I get a valid result: mysql> SELECT (`nested` + 1) AS `nest` FROM `ipspace6` WHERE `id`<=50552019054038629283648959286463168512 AND `subnet`<=36 AND `type`='net' AND `addr` NOT IN (SELECT `id` FROM `ipspace6` WHERE `addr`<50552019054038629283648959286463168512 AND `type`='broadcast') ORDER BY `id`,`subnet` DESC LIMIT 1; +------+ | nest | +------+ | 1 | +------+ 1 row in set (0.00 sec) Can anybody tell me what I'm doing wrong? I can't put quotes around my variables, as then MySQL will try to evaluate the variable as a string, when it is, in fact, a very large decimal. I think I might just be making a stupid mistake somewhere, but I can't tell where.

• NHibernate + Fluent long startup time

  - by PaRa

  Hi all, am new to NHibernate. When performing below test took 11.2 seconds (debug mode) i am seeing this large startup time in all my tests (basically creating the first session takes a tone of time) setup = Windows 2003 SP2 / Oracle10gR2 latest CPU / ODP.net 2.111.7.20 / FNH 1.0.0.636 / NHibernate 2.1.2.4000 / NUnit 2.5.2.9222 / VS2008 SP1 using System; using System.Collections; using System.Data; using System.Globalization; using System.IO; using System.Text; using System.Data; using NUnit.Framework; using System.Collections.Generic; using System.Data.Common; using NHibernate; using log4net.Config; using System.Configuration; using FluentNHibernate; [Test()] public void GetEmailById() { Email result; using (EmailRepository repository = new EmailRepository()) { results = repository.GetById(1111); } Assert.IsTrue(results != null); } public class EmailRepository : RepositoryBase { public EmailRepository():base() { } } In my RepositoryBase public T GetById(object id) { using (var session = sessionFactory.OpenSession()) using (var transaction = session.BeginTransaction()) { try { T returnVal = session.Get(id); transaction.Commit(); return returnVal; } catch (HibernateException ex) { // Logging here transaction.Rollback(); return null; } } } The query time is very small. The resulting entity is really small. Subsequent queries are fine. Its seems to be getting the first session started. Has anyone else seen something similar?

• setting the openCV configuration in an openGL project produce several errors

  I have a win32 solution which is set for openGL; it works well; but I want to write a function which use functions of openCV; I set the configuration for openCV for both X86 and X64;;I commented the openCV function and just to test the correctness of configuration, I run it; but when I want to run it on X64 I faced with the error below: Error 1 error C2065: 'GWL_HINSTANCE' : undeclared identifier D:\matrix\matrixProjection\src\ControllerMain.cpp 35 1 matrixProjection Error 2 error C2664: 'CreateDialogParamW' : cannot convert parameter 4 from 'BOOL (__cdecl *)(HWND,UINT,WPARAM,LPARAM)' to 'DLGPROC' D:\matrix\matrixProjection\src\DialogWindow.cpp 47 1 matrixProjection Error 2 points to this line of code: HWND DialogWindow::create() { /*-->this line*/ handle = ::CreateDialogParam(instance, MAKEINTRESOURCE(id), parentHandle, Win::dialogProcedure, (LPARAM)controller); return handle; } but on Debug Win32 configure, it runs; I used openGL32 in my project; is there any probability to be the cause? is there any X64 version for openGL? I know that there is something needed in X64 mode which my solution can not handle it; I googled a lot about it but I did not find any solution; How can I solve that?

• Compiling GWT 2.6.1 at Java 7 source level

  - by Neeko

  I've recently updated my GWT project to 2.6.1, and started to make use of Java 7 syntax since 2.6 now supports Java 7. However, when I attempt to compile, I'm receiving compiler errors such as [ERROR] Line 42: '<>' operator is not allowed for source level below 1.7 How do I specify the GWT compiler to target 1.7? I was under the impression that it would do that by default, but I guess not. I've attempted cleaning the project, including deleting the gwt-unitCache directory but to no avail. Here is my Ant compile target. <target name="compile" depends="prepare"> <javac includeantruntime="false" debug="on" debuglevel="lines,vars,source" srcdir="${src.dir}" destdir="${build.dir}"> <classpath refid="project.classpath"/> </javac> </target> <target name="gwt-compile" depends="compile"> <java failonerror="true" fork="true" classname="com.google.gwt.dev.Compiler"> <classpath> <!-- src dir is added to ensure the module.xml file(s) are on the classpath --> <pathelement location="${src.dir}"/> <pathelement location="${build.dir}"/> <path refid="project.classpath"/> </classpath> <jvmarg value="-Xmx256M"/> <arg value="${gwt.module.name}"/> </java> </target>

• odd behavior with C# ftp client class

  - by geoff

  I found an ftp client class in c# over a year ago and have been using it in a process that uploads files on a nightly basis. A few days ago we started having a problem where it would time out. I'm not well versed in this so I'm not sure why it's doing this. When the program starts uploading a file it checks to see if it's logged in and if not, it calls the login method. In that method is this block of code. if (this.resultCode != 230) { this.sendCommand("PASS " + password); if (!(this.resultCode == 230 || this.resultCode == 202)) { this.cleanup(); throw new FtpException(this.result.Substring(4)); } } On the line that says this.sendCommand("PASS"... it goes into this code. private void sendCommand(String command) { if (this.verboseDebugging) Debug.WriteLine(command, "FtpClient"); Byte[] cmdBytes = Encoding.ASCII.GetBytes((command + "\r\n").ToCharArray()); clientSocket.Send(cmdBytes, cmdBytes.Length, 0); this.readResponse(); } If I let the program run, it times out. However if I step through it into the sendCommand method it executes fine. Does anyone know why it would work fine when I step through it? Nothing on our end has changed and I've been told nothing on the client's end has changed so I'm stumped. Thanks.

• Evaluating expressions using Visual Studio 2005 SDK rather than automation's Debugger::GetExpression

  - by brone

  I'm looking into writing an addin (or package, if necessary) for Visual Studio 2005 that needs watch window type functionality -- evaluation of expressions and examination of the types. The automation facilities provide Debugger::GetExpression, which is useful enough, but the information provided is a bit crude. From looking through the docs, it sounds like an IDebugExpressionContext2 would be more useful. With one of these it looks as if I can get more information from an expression -- detailed information about the type and any members and so on and so forth, without having everything come through as strings. I can't find any way of actually getting a IDebugExpressionContext2, though! IDebugProgramProvider2 sort of looks relevant, in that I could start with IDebugProgramProvider2::GetProviderProcessData and then slowly drill down until reaching something that can supply my expression context -- but I'll need to supply a port to this, and it's not clear how to retrieve the port corresponding to the current debug session. (Even if I tried every port, it's not obvious how to tell which port is the right one...) I'm becoming suspicious that this simply isn't a supported use case, but with any luck I've simply missed something crashingly obvious. Can anybody help?

• Is there any reason why jQuery Sortable would work in IE/Chrome but not Firefox?

  - by DNS

  I have a fairly straightforward list of horizontally floated items, like this: <div class="my-widget-container"> <div class="my-widget-column">...</div> ... </div> Both the container and each column have a fixed width, set using jQuery's .width(). The container is position: relative and the column is float: left and overflow: hidden. Not sure if any other styles/properties are relevant. When I apply a jQuery-UI sortable to this, the result is exactly what I'd expect in Chome 8 and IE 8; the columns can be dragged around to change their order. But in Firefox 3.6 I can click an item and drag to create a new sort-helper, yet the actual sort never happens; the real item's position in the DOM never changes. I dug around a little in Sortable, and added a debug print to _intersectsWithPointer. Whenever the drag helper moves, Sortable runs through its list of elements and uses this method to determine whether the drag helper has passed over one. What I saw was that item.left had the same value for all my columns, which is obviously not correct, and probably the source of the problem. It looks like all columns had a left position corresponding to that of the first column. I'm using jQuery 1.4.3 and jQuery UI Sortable 1.8. Those aren't the very latest versions, but they're pretty recent, and I don't see anything in the Sortable release notes that indicates any such problem has been fixed. Does anyone know what might be happening here, or have any ideas for further debugging?

• Connect to Facebook with Javascript Client Library using Adobe AIR

  I'm having an issue connecting to Facebook through the Javascript Client Library in Adobe AIR. It works fine in the browser but in Adobe AIR it seems to not be able to find the Facebook functions. Here is some code I copied from the Facebook website: (Oh and I have the xd_receiver.htm file in the correct path too) <textarea style="width: 1000px; height: 300px;" id="_traceTextBox"> </textarea> <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script> // var api = FB.Facebook.apiClient; // require user to login api.requireLogin(function(exception){ FB.FBDebug.logLevel=1; FB.FBDebug.dump("Current user id is " + api.get_session().uid); // Get friends list //5-14-09: this code below is broken, correct code follows //api.friends_get(null, function(result){ // Debug.dump(result, 'friendsResult from non-batch execution '); // }); api.friends_get(new Array(), function(result, exception){ FB.FBDebug.dump(result, 'friendsResult from non-batch execution '); }); }); }); //]]> </script>

• Strange behavior with ajax call complete in JavaScript modules

  - by user2598794

  I have 3 simple modules with JavaScript code and JQuery ajax call. First module lots.js: var Lots = (function ($) { var self = this; var processIsRunning; return { getLots: function (lotsUrl) { var items = []; self.processIsRunning = true; var request = $.ajax({ url: lotsUrl, type: 'POST', success: function (data) { //some code } }); $.when(request).done(function() { //some code self.processIsRunning = false; }); }, isComplete: function () { return !self.processIsRunning; } }; }(jQuery)); Module bids.js: var Bids = (function ($) { return { makeBids: function (bidUrl) { //some code } }; }(jQuery)); Module app.js which bundles all together: var App = (function () { var lots_url = null; var bid_url = null; var self = this; return { if (!self.lots_url) { self.lots_url = lotsUrl; } GetLots: function (lotsUrl) { Lots.getLots(self.lots_url); }, MakeBids: function makeBid(bidUrl) { //some code var isComp = Lots.isComplete(); while (!isComp) { isComp = Lots.isComplete(); } Bids.makeBids(self.bid_url); } }; }()); But in the 'while' loop I always get 'isComplete=false'. In debug I see that 'processIsRunning' in Lots module is always true. What's the problem?

• Windows Forms application C# | Sending Tweet

  I've been able to get my Twitter web app working just fine, but I've recently decided to add Tweeting functionality from a Windows Form, but I'm having no luck sending tweets. No errors are thrown or anything. Mind looking over my code? using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using TweetSharp; namespace TwitterAdvirtiser { public partial class Form1 : Form { private string cKey = "xxx"; private string cSecret = "xxx"; private string oToken = "xxx"; private string aToken = "xxx"; public Form1() { InitializeComponent(); OnStart(); } private void OnStart() { //Authenticate with Twitter TwitterService service = new TwitterService(cKey, cSecret); service.AuthenticateWith(oToken, aToken); service.SendTweet("testing"); } } } It seems like I'm authenticating just fine, I can walk through debug mode and see all my details in the TwitterUser structure, and yet my tweets never show up on my feed. Whats up? By the way, I'm using Visual Studios 2010, and .NET 4.0. I have verified that the oToken and aToken strings have my developer tokens.

• How to avoid resetting the java Scanner position

  - by Derek

  I have some code that looks more or less like this: while(scanner.hasNext()) { if(scanner.findInLine("Test") !=null) { //do some things }else{ scanner.nextLine(); } } I am using this to parse an ~10MB text file. The problem is, if I put a breakpoint on the while() and the scanner.nextLine(), I can see that sometimes the scanners position (in the debug window) goes back to zero. I think this is causing me some kind of loop blow up, because the regext in findInLine() starts at zero, looks through some amount of text, advancing the position, and then it randomly gets set back to zero, so it has to re-parse all that text again. Any ideas what can be causing that? Am I even doing this the right way? Thanks Some additional info: The Scanner is instantiated from an InputStream. After diubg sine debugging, it appears that there is a HearCharBuffer that Scanner uses and it only allows 1024 characters at a time, and then resets. Is there a way to avoid this, or do things differently? That seems like a small amount of characters to be able to scan. Derek

• why does setting stderr=subprocess.STDOUT fix a subprocess.check_output call?

  - by ShankarG

  I have a python script running on a small server that is called in three different ways - from within another python script, by cron, or by gammu-smsd (an SMS daemon with the wonderful mobile utility [gammu]). The script is for maintenance and contained the following kludge to measure used space on the system (presumably this is possible from within Python, but this was quick and dirty): reportdict['Used Space'] = subprocess.check_output(["df / | tail -1 | awk '{ print $5; }'"], shell=True)[0:-1] Oddly enough this line would only fail when the script was called by a shell script running from gammu-smsd. The line would fail with a CalledProcessError exception saying "returned exit status 2", even though the output attribute of the CalledProcessError object contained the correct output. The only command in the sequence of shell commands that would give such an error status would be awk, with status 2 indicating a fatal error. If the python script with this line was called by cron, by another python script, or from the command line, this line would work fine. I broke my head trying to fix the environment for the script, thinking this must be the problem. Finally though I put in stderr=subprocess.STDOUT, like so: reportdict['Used Space'] = subprocess.check_output(["df / | tail -1 | awk '{ print $5; }'"], stderr=subprocess.STDOUT, shell=True)[0:-1] This was a debug measure to help me figure out if some output was coming on stderr. But after this the script started working, even when called from gammu-smsd! Why might this be the case? I ask for future reference when using subprocess...

• Probelem, executing commands in cmd using c#

  - by srk

  I need to execute the below command in command prompt. C:\MySQL\MySQL Server 5.0\bin>mysql -uroot -ppassword < d:/admindb/aar.sql When i do this manually in cmd, i am getting my results. Now i am trying to do this programatically, to execute it in cmd from c# code. I am using the below code to do it. I am not getting any errors and Result !!! When i debug, i get the value of string commandLine as below, "\"C:\\MySQL\\MySQL Server 5.0\\bin\\\" -uroot -ppassword > \"D:/admindb/AAR12.sql" I guess the problem is with this string, passed to cmd. How to solve this ??. public void Execute() { string commandLine = "\"" + MySqlCommandPath + "\"" + " -u" + DbUid + " -p" + DbPwd + " > " + "\"" + Path.Combine(Path_Backup, FileName_Backup + ExcID + ".sql"); System.Diagnostics.ProcessStartInfo PSI = new System.Diagnostics.ProcessStartInfo("cmd.exe"); PSI.RedirectStandardInput = true; PSI.RedirectStandardOutput = true; PSI.RedirectStandardError = true; PSI.UseShellExecute = false; System.Diagnostics.Process p = System.Diagnostics.Process.Start(PSI); System.IO.StreamWriter SW = p.StandardInput; System.IO.StreamReader SR = p.StandardOutput; SW.WriteLine(commandLine); SW.Close(); }

• Flex/Actionscript image display problem.

  - by IanH

  I'm trying to extend the Image class but hit a problem that I can't get past. I have a private image (img) that loads an image and a function that takes that image and copies it onto the parent. The debug function "copyit2" displays the image fine (so I know it's loaded OK). But the function "copyit" doesn't work - it just displays a white rectangle. I can't see how to make copyit work so that the original image is copied to the BitmapData and then subsequenty copied onto the parent? (The idea is to do some processing on the Bitmap data before it is displayed, although this isn't shown here to keep the example simple.) I suspect it is something to do with the security of loading images, but I'm loading it from the same server as the application is run from - so this shouldn't be a problem? Thanks for any help anyone can provide. Ian package zoomapackage { import flash.display.Bitmap; import flash.display.BitmapData; import flash.display.Sprite; import flash.events.MouseEvent; import flash.geom.Matrix; import flash.geom.Point; import flash.geom.Rectangle; import flash.net.*; import mx.controls.Image; import mx.events.FlexEvent; public dynamic class Zooma extends Image { private var img:Image; public function copyit():void { var imgObj:BitmapData = new BitmapData(img.content.width, img.content.height, false); imgObj.draw(img); var matrix:Matrix = new Matrix(); this.graphics.beginBitmapFill(imgObj, matrix, false,true); this.graphics.drawRect(0, 0, this.width , this.height); this.graphics.endFill(); } public function copyit2():void { this.source = img.source; } public function Zooma() { super(); img = new Image(); img.load("http://localhost/Koala.jpg"); } } }
