  • Permission Denied error in IE when closing popups

    - by Kenia
    Hi everyone! I have a simple web testing application which is supposed to open and close several popups by itself (without user interaction). For this purpose i have a javascript function to access the variable where the popup reference is stored and close it if it´s not null, fairly simple. However I get random errors in IE (in FF it works as expected, all popups are closed correctly) like Message: No such interface supported Line: 86 Char: 3 Code: 0 URI: http://10.10.0.61:10000/savmailer/adm/tests/common_tests_code.js and Message: Permission denied Line: 86 Char: 3 Code: 0 URI: http://10.10.0.61:10000/savmailer/adm/tests/common_tests_code.js The line 86 references exactly the point at which I do popup.close(); in the following function function closePopupWindow(popup){ if (popup != null) { popup.close(); popup = null; } } I have googled and it seems this permission denied error is quite common to come through among IE developers, however there´s no clear solution for it, it´s just a matter of changing the code slightly "to please" IE, so to speak. However i have no idea how to change mine since it´s just 3 lines! Tried also to change the security browser settings by adding my domain to the trusted zone, but nothing, doesn't help either. If anyone has any helpful idea or notices something i might be forgetting, please, reply to this! Thanks in advance, Kenia

  • Using a CNAME with Shared Windows Azure Website

    - by user1679021
    I've been following instructions on the Azure site to add a CNAME to point to my Azure website. I have had some problems getting it to work and there seems to be some contradictory information in some of the posts. I have my website running in "Shared" mode, which according to the Azure instructions supports custom domains and indeed it seems to allow me to manage domains. But some posts seem to indicate that I have to run in reserved mode. Can anyone confirm this? Also, some posts seem to indicate that I need to add the CNAME in the Azure management portal, but I cannot find where this is. Any help appreciated? I don't really understand A records and CNAME that well. My DNS provider allows me to add both. Do I need to change both? Currently my A record points the "root" to the IP address that Azure gives me and the CNAME points www.mydomain to the Azure website host mysite.azurewebsites.net. I have left them for a while to propogate and nothing seem to happen.

  • Fluent NHibernate no data being returned

    - by czuroski
    Hello, I have been successfully using NHibernate, but now I am trying to move to Fluent NHibernate. I have created all of my mapping files and set up my session manager to use a Fluent Configuration. I then run my application and it runs successfully, but no data is returned. There are no errors or any indication that there is a problem, but nothing runs. when using NHibernate, if I don't set my hbm xml files as an embedded resource, this same thing happens. This makes me wonder what I have to set my Map classes to. Right now, they are just set to Compile, and they are compiled into the dll, which I can see by disassembling it. Does anyone have any thoughts as to what may be happening here? Thanks private ISessionFactory GetSessionFactory() { return Fluently.Configure() .Database( IfxOdbcConfiguration .Informix1000 .ConnectionString("Provider=Ifxoledbc.2;Password=mypass;Persist Security Info=True;User ID=myuser;Data Source=mysource") .Dialect<InformixDialect1000>() .ProxyFactoryFactory<ProxyFactoryFactory>() .Driver<OleDbDriver>() .ShowSql() ) .Mappings( m => m.FluentMappings .AddFromAssemblyOf<cmCase>() .AddFromAssemblyOf<attorney>() .AddFromAssemblyOf<creditor>() .AddFromAssemblyOf<party>() .AddFromAssemblyOf<person>() .AddFromAssemblyOf<sardbk>() .AddFromAssemblyOf<schedule>() //x => x.FluentMappings.AddFromAssembly(System.Reflection.Assembly.GetExecutingAssembly()) //.ExportTo("C:\\mappings") ) .BuildSessionFactory(); }

  • Load Empty Database table

    - by john White
    I am using SQLexpress and VS2008. I have a DB with a table named "A", which has an IdentitySpecification column named ID. The ID is auto-incremented. Even if the row is deleted, the ID still increases. After several data manipulation, the current ID has reached 15, for example. When I run the application if there's at least 1 row: if I add a new row, the new ID is 16. Everything is fine. If the table is empty (no row): if I add a new row, the new ID is 0, which is an error (I think). And further data manipulation (eg. delete or update) will result in an unhandled exception. Has anyone encountered this? PS. In my table definition, the ID has been selected as follow: Identity Increment = 1; Identity Seed =1; The DB load code is: dataSet = gcnew DataSet(); dataAdapter->Fill(dataSet,"A"); dataTable=dataSet->Tables["A"]; dbConnection->Open(); The Update button method dataAdapter->Update(dataSet,"tblInFlow"); dataSet->AcceptChanges(); dataTable=dataSet->Tables["tblInFlow"]; dataGrid->DataSource=dataTable; If I press Update: if there's at least a row: the datagrid view updates and shows the table correctly. if there's nothing in the table (no data row), the Add method will add a new row, but from ID 0. If I close the program and restart it again: the ID would be 16, which is correct. This is the add method row=dataTable->NewRow(); row["column1"]="something"; dataTable->Rows->Add(row); dataAdapter->Update(dataSet,"A"); dataSet->AcceptChanges(); dataTable=dataSet->Tables["A"];

  • Setting Icon for wpf application (VS 08)

    - by baron
    Hi everyone, Before going much further i'll mention I have tried solutions in following: http://stackoverflow.com/questions/320677/how-do-i-set-the-icon-for-my-application-in-visual-studio-2008 http://stackoverflow.com/questions/198848/set-application-icon-from-resources-in-vs-05 I am trying to set an icon for my application. AFAIK, I need potentially 3 images? 1 image is the actual image in explorer when clicking on the .exe (thumbnail for the exe) 1 image (tiny) in the top left corner (16 x 16? Not entirely sure) 1 image in the start menu dock, to the left of the app (maybe 32x32? again not sure) So thats fine. Now I have selected an Icon. How do I use it in one of above situations? I have tried adding it in resources, nothing seems to happen. Following that first SO solution, "First go to Resource View (from menu: View -- Other Window -- Resource View). Then in Resource View navigate through resources, if any. If there is already a resource of Icon type, added by Visual Studio, then open and edit it. Otherwise right-click and select Add Resource, and then add a new icon." The resource view is empty, and I cannot right click in this view. If I right click on the solution properties resources I can add the icon image, but it doesn't show in either of the locations listed above. (or anywhere that I can see) What am I doing wrong?

  • NullPointerException on Activity Testint Tutorial

    - by Bendik
    Hello, I am currently trying the activity testing tutorial (Found here), and have a problem. It seems that whenever I try to call something inside the UIThread, I get a java.lang.NullPointerException. public void testSpinnerUI() { mActivity.runOnUiThread( new Runnable() { public void run() { mSpinner.requestFocus(); } }); } This gives me: Incomplete: java.lang.NullPointerException and nothing else. I have tried this on two different samples now, with the same result. I tried with a try/catch clause around the mSpinner.requestFocus() call, and it seems that mSpinner is null inside the thread. I have set it properly up with the setUp() function found in the same sample, and a quick assertNotNull( mSpinner ) shows me that mSpinner is in fact not null after the setUp() function. What can be the cause of this? EDIT; ok, some more testing has been done. It seems that the application that is being tested resets between each test. This essentially makes me have to reinstantiate all variables between each test. Is this normal?

  • Configuration Error , Finding assembly after I swapped referenced dll out. Visual Studio 2003

    - by TampaRich
    Here is the situation. I had a clean build of my asp.net web application working. I then went into the bin folder under the web app and replaced two referenced dll's with two older version of the same dll's. (Same name etc.) After testing I replaced those dll's back to the new ones and now my application keeps throwing the configuration error === Pre-bind state information === LOG: DisplayName = xxxxx.xxxx.Personalization (Partial) LOG: Appbase = file:///c:/inetpub/wwwroot/appname LOG: Initial PrivatePath = bin Calling assembly : (Unknown). LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind). I found this issue on the web and tried all the solutions to it but nothing worked. I then went into all my projects that it references under the solution and cleared out the bin/debug folder in each, I cleared out the obj folder under each and also deleted the temporary files associated with the application. I rebuilt it and it still will not work due to this error Not sure what is causing this or how to fix this issue. I have tried restarting IIS, stopping index services which was said to be a known issue. This is .net framework 1.1 app and visual studio 2003 Any suggestions would be great. Thanks.

  • Does anyone know of any good tutorials for using the APIs from Amazon WeB Services, namely CloudWatc

    - by undefined
    Hi, I have been wrestling with Amazon's CloudWatch API with limited success. Does anyone know of any good resources (other than amazon's api docs) for using the APIs. I have tried to run them using the PHP library for CloudWatch but get nothing but error codes. I am configuring the GetMetricStatisticsSample.php file as follows: $request = array(); $endTime = date("Y-m-d G:i:s"); $yesterday = mktime (date("H"), date("i"), date("s"), date("m"), date("d")-1, date("Y")); $startTime = date("Y-m-d 00:00:00", $yesterday); $request["Statistics.member.1"] = "Average"; $request["EndTime"] = $endTime; $request["StartTime"] = $startTime; $request["MeasureName"] = "CPUUtilization"; $request["Unit"] = "Percent"; invokeGetMetricStatistics($service, $request); But this returns "Caught Exception: Internal Error Response Status Code: 400 Error Code: Error Type: Request ID: XML:" I have also tried from command line as follows - set JAVA_HOME=C:\Program Files\Java\jre1.6.0_05 set AWS_CLOUDWATCH_HOME=C:\AmazonWebServices\API_tools\CloudWatch-1.0.0.24 set PATH=%AWS_CLOUDWATCH_HOME%\bin mon-list-metrics but get C:|Program' is not recognized as an internal or external command... any suggestions? cheers

  • PDFBox Pagebreak strange Nullpointer exception

  • How can I use "PHP Simple HTML DOM Parser" to get the contents of an <h1></h1> tag?

    - by KeriLynn
    I'm new to PHP =) Right now I am using PHP includes for my site template. I have my header, containing all my <head></head> info. What I want to do is write a code that will take the contents of the <h1></h1> tag from the page, and echo it into the <title></title> tag in my header.php include. I got the PHP Simple HTML DOM Parser from here: http://simplehtmldom.sourceforge.net/, and I found a code (I forget where in all my googling) that goes like this: <?php $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $html = file_get_html('http://www.google.com/'); foreach($html->find('#content h1') as $element){ echo $element->plaintext;} ?> That I think is supposed to echo the h1 tag contents? Like I said, I'm new to PHP and I only know the basics, and I don't know really know any OOP (yet), so I'm sorry if I'm asking a dumb question. It looks like it's getting the current page, then putting the contents of the h1 tag into the variable $element, and then echoing it. But nothing happens when I put it into my page. Can anyone help me with what I'm doing wrong? Thank you for reading!! =)

  • Redirecting Pages with PHP causing problems

    - by psp
    I have a page which has a link to a php page which takes data from $_GET and updates a database. After that it returns the user to the homepage with: header("Location: http://localhost/"); The thing is that this seems to "interrupt" the mysql part of the code. If I remove this redirect, everything in the database is updated, but when I put it back, nothing gets updated... This is the database update code, I am using a class of mine as a mysql wrapper: $conn->where('hash',$data1['hash']); $conn->update(TABLE_ITEMS,$newData1); $conn->where('hash',$data2['hash']); $conn->update(TABLE_ITEMS,$newData2); Notes: -There is no text or echo()'s on the page and no space before the <?php tag Order of Code: Data received from $_SESSION and $_GET Data processed and placed into arrays Data placed into mysql database header(); used to redirect page Code <?php require_once('config.php'); import(); if ( isset ( $_GET['g'] ) && isset ( $_SESSION['itemA'] ) && isset ( $_SESSION['itemB'] ) ) { $itemA = $_SESSION['gameA']; $itemB = $_SESSION['gameB']; $newData1 = processData($itemA); $newData2 = processData($itemB); $conn->update(TABLE_ITEMS,$newData1); $conn->update(TABLE_ITEMS,$newData2); header('Location: http://localhost/'); } else { header('Location: http://localhost/'); }

  • Canvas - @font-face doesn't work on IE9+

    - by iMoses
    I've created a widget which allows the user to locate free-text over an image using a textarea. When saving the image a background canvas application reads the text and calculates its position, then it draws the text to the canvas over the image and saves a new image file. The font I use for this widget is league-gothic which I am importing using the @font-face method. This seems to work great and without any issues on all browsers except (of-course) for IE9 and IE10. When using internet explorer you can clearly see that the font was indeed loaded since the textarea uses the same font, but when trying to draw the text onto the canvas the font-family reverts to one of its fallback, in this case Arial. I've searched quite a bit and found nothing. Unlike most font issues I found that concern the canvas element, I am completely sure that the font has indeed loaded as I am viewing it before saving the result. Anything at all will help me at the moment. If you have any insight, experience with similar bugs or whatever, please share :) Thanks in advance. P.S. I can't expose a code example at the moment, but if it becomes a problem I'll do my best to provide one.

  • How to check the correct radio button.

    - by MrW
    I have a Table containing some information that I need. All these rows also contains a column with a radio button in it so that the user is suppose to be able to check one of the rows as default. When I'm bringing the data back from the DB and want to select the one that's currentlly the default one. <% foreach (var item in (IEnumerable<Locale>) ViewData["Locales"]) { %> <tr> <td> <%= Html.Encode(item.Language.Name) %> </td> <td> <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%= item.Default == false ? "false" : "true" %>" /> </td> I've also tried to do this: <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%=item.Default == false ? "" : "checked" %>" /> but nothing seems to do the right thing. I always end up with having the last row in checked, which it isn't for sure.

  • jquery pagination plugin doesn't quite work right for me...

Any suggestion how to get this done.......

  • how are association, aggregation and composition written?

    - by ajsie
    i have read some posts about the differences between these 3 relationships and i think i get the point. i just wonder, are all these written the same when coding? question 1: all 3 are just a value of the object type in a instance variable? class A { public $b = '' public function __construct($object) { $this->b = $object // <-- could be a association, aggregation or a composition relation? } } question 2: does it have to be an instance variable or can it be a static one? class A { public static $b = '' // <-- nothing changed? public function __construct($object) { $this->b = $object } } question 3: is there a difference in where the object is created? i tend to think that composition object is created inside the object: class A { public $b = '' public function __construct() { $this->b = new Object // is created inside the object } } and aggregation/association is passed through a constructor or another method: class A { public $b = '' public function __construct($object) { // passed through a method $this->b = $object } } question 4: why/when is this important to know. do i have to comment an object inside another what relation its about or do you do it in an UML diagram? could someone shed a light on these questions. thanks!

  • Search Box/Transition won't work in Firefox

    - by user2522488
    I disabled the search box on IE, because IE kept centering it over the navigation. It works in Chrome, I'm not sure about opera (and I'm not sure if I care) but it won't work in Firefox. The ease-out timing works in Firefox, but nothing else really works. I've tried other things to work around the issue, but every time I try something different, the search box's positioning gets thrown off. If you look at it in Firefox, it looks fine-- until you click on it to search. http://kissoff.weebly.com/ You can see what the search box is supposed to do if you look at it and click on it in Chrome. I'm sure the positioning is off, I'm not sure (I'm new to css). Any help is appreciated. #search {} #search input[type="text"] { background: url(search-white.png) no-repeat 10px 6px #fcfcfc; border: 1px solid #d1d1d1; position: fixed; margin-left: 350px; margin-right: 0px; margin-top: 0px; color: #bebebe; width: 150px; padding: 6px 15px 6px 35px; -webkit-border-radius: 20px; -moz-border-radius: 20px; border-radius: 20px; text-shadow: 0 2px 3px rgba(0, 0, 0, 0.1); -webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -moz-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -webkit-transition: all 0.7s ease 0s; -moz-transition: all 0.7s ease 0s; -o-transition: all 0.7s ease 0s; transition: all 0.7s ease 0s; float: right; } #search input[type="text"]:focus { width: 200px; }

  • strtotime not working with TIME?

    - by Prashant
    My mysql column has this datetime value, 2011-04-11 11:00:00 when I am applying strtotime then its returning date less than today,whereas it should be greater than today. also when I am trying this strtotime(date('d/m/Y h:i A')); code, its returning wrong values. Is there any problem with giving TIME in strtotime? Basically I want to do, is to compare my mysql column date with today's date, if its in future then show "Upcoming" else show nothing? Please help and advise, what should I do? Edited code $_startdatetime = $rs['startdatetime']; $_isUpcoming = false; if(!empty($_startdatetime)){ $TEMP_strtime = strtotime($_startdatetime); $TEMP_strtime_today = strtotime(date('d/m/Y h:i A')); if($TEMP_strtime_today < $TEMP_strtime){ $_isUpcoming = true; $_startdatetime = date('l, d F, Y h:i A' ,$TEMP_strtime); } } And the value in $rs['startdatetime'] is 2011-04-11 11:00:00. And with this value I am getting following output. $TEMP_strtime - 1302519600 $TEMP_strtime_today - 1314908160 $_startdatetime - 2011-04-11 11:00:00 $_startdatetime its value is not formatted as the upcoming condition is false, so returning as is mysql value.

  • Polling a web URL until event

    - by Jaxo
    I'm really sorry about the crappy title - if anybody has a better way of wording it, please edit it! I basically need to have a C# application run a function if the output of a URL is a certain value. For example, if the website says blue the background colour will be blue, red to make it red, etc. The problem is I don't want to spam my webserver with checks. The 4 bytes it downloads each time is negligible, but if I were to deploy this type of system on multiple computers, it would get slower and slower and the bandwidth would add up quickly. So my question is: How can my desktop application run a piece of code only when a web URL has a different output without checking each time? I can't use sockets, and any sort of LAN protocol won't end up working. My reasoning behind this potentially nefarious code is to be able to mute computers by updating a file on the website (as you may have seen in my previous question today, sorry!). I'd like it to be rather quick, and not have the refresh time minutes apart, a few seconds at the most would be ideal. How can I accomplish this? The website's code is easy, but getting the C# application to check when it changes is the part I'm stuck on. Nothing shows up on the website other than the command. Thanks!

  • iPhone rotation woes

    - by skooter500
    I have been spending many frustrating hours trying to get rotations working on the iPhone version of Tunepal. Firstly, I have a tab bar controller, with a navigation controller controlling each of the views. I actually only want one of my views to be able to rotate and that is the TuneDisplay. I have a subclassed the UITabBarController and overridden theshouldAutorotateToInterfaceOrientation: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation { if (self.selectedViewController != nil) { return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation]; } else { return (interfaceOrientation == UIInterfaceOrientationPortrait); } } In each of the view controllers for each of the tabs I have overridden the method and returned YES for each orientation I want to support. All well and good and everything works as it should. If I try and do a rotation on a tab that doesn’t support the rotation, nothing happens. The problem occurs if I move from a tab thats rotated to a tab that isnt supposed to support that rotation. The new tab is displayed rotated too! Screenshots for all this are included here: http://tunepal.wordpress.com/2010/04/20/rotation-woes/ Is there any way I can make it rotate back to portrait on tapping the tab? I have tried the unsupported setOrientation trick, but firstly it doesnt work correctly and secondly I received a warning from Apple for including it in my last build. If (as I suspect) there is no way to limit this behavior: How do I make the microphone image scale when I rotate the device? How do I make the buttons and the progress bar expand to fit the witdh of the toolbar? Also, one of the tabs that rotates ok has a table, with a search bar. The first time I rotate to the right or to the left, I get a black bar to the right of the search bar. If I subsequently rotate back and rotate again, the bar disappears! I have enabled the struts and springs things on the search bar in the interface builder and it looks like it should behave correctly. Any ideas about how to fix this? Ideas, feedback much appreciated Bryan

  • "pseudo-atomic" operations in C++

    - by dan
    So I'm aware that nothing is atomic in C++. But I'm trying to figure out if there are any "pseudo-atomic" assumptions I can make. The reason is that I want to avoid using mutexes in some simple situations where I only need very weak guarantees. 1) Suppose I have globally defined volatile bool b, which initially I set true. Then I launch a thread which executes a loop while(b) doSomething(); Meanwhile, in another thread, I execute b=true. Can I assume that the first thread will continue to execute? In other words, if b starts out as true, and the first thread checks the value of b at the same time as the second thread assigns b=true, can I assume that the first thread will read the value of b as true? Or is it possible that at some intermediate point of the assignment b=true, the value of b might be read as false? 2) Now suppose that b is initially false. Then the first thread executes bool b1=b; bool b2=b; if(b1 && !b2) bad(); while the second thread executes b=true. Can I assume that bad() never gets called? 3) What about an int or other builtin types: suppose I have volatile int i, which is initially (say) 7, and then I assign i=7. Can I assume that, at any time during this operation, from any thread, the value of i will be equal to 7? 4) I have volatile int i=7, and then I execute i++ from some thread, and all other threads only read the value of i. Can I assume that i never has any value, in any thread, except for either 7 or 8? 5) I have volatile int i, from one thread I execute i=7, and from another I execute i=8. Afterwards, is i guaranteed to be either 7 or 8 (or whatever two values I have chosen to assign)?

  • Why does my simple event handling example not work?

    - by njreed
    I am trying to make a simple event handler. (Note, I'm not trying to implement a full-blown publish/subscribe model; I'm just interested in why my example doesn't work as I think it should) var myObj = (function () { var private = "X"; function triggerEvent(eventName) { if (this[eventName]) { this[eventName](); } } // Setter / Getter function getProp() { return private; } function setProp(value) { private = value; triggerEvent("onPropChange"); } // Public API return { // Events "onPropChange": null, // Fires when prop value is changed // Methods "getProp": getProp, "setProp": setProp }; })(); // Now set event handler myObj.onPropChange = function () { alert("You changed the property!"); }; myObj.setProp("Z"); // --> Nothing happens. Wrong // Why doesn't my alert show? I set the onPropChange property of my object to a simpler handler function but it is not being fired. I have debugged this and it seems that in triggerEvent the variable this is referencing the global window object. I thought it should reference myObj (which is what I need). Can someone explain the error in my thinking and how I correct this? Help much appreciated. jsFiddle here

  • Jquery conditionals, window locations, and viewdata. Oh my!

    - by John Stuart
    I have one last thing left on a project and its a doozy. Not only is this my first web application, but its the first app i used Jquery, CSS and MVC. I have no idea on how to proceed with this. What i am trying to do is: In my controller, a waste item is validated, and based on the results one of these things can happen. The validation is completed, nothing bad happens, which sets ViewData["FailedWasteId"] to -9999. Its a new waste item and the validation did not pass, which sets ViewData["FailedWasteId"] to 0. Its an existing waste item and the validation did not pass, which sets ViewData["FailedWasteId"] to the id of the waste item. This ViewData["FailedWasteId"] is set on page load using <%=Html.Hidden("wFailId", int.Parse(ViewData["WasteFailID"].ToString()))%> When the validations do not pass, then the page zooms (by window.location) to an invisible div, opens the invisible div etc. Hopefully my intentions are clear with this poor attempt at jquery. The new waste div is and the existing item divs are dynamically generated (this i know works) " So my question here is... Help? I cant even get the data to parse correctly, nor can i even get the conditionals to work. And since this happens after post, i cant get firebug to help my step through the debugger, as the script isnt loaded yet. $(document).ready(function () { var wasteId = parseInt($('#wFailId').text()); if (wasteId == -9999) { //No Issue } else if (wasteId < 0) { //Waste not saved to database } else if (wasteId == 0) { //New Waste window.location = '#0'; $('.editPanel').hide(); $('#GeneratedWasteGrid:first').before(newRow); $('.editPanel').appendTo('#edit-panel-row').slideDown('slow'); } else if (wasteId > 0) { //Waste saved to database } });
