• phpUnit - mock php extended exception object

  - by awongh

  I'm testing some legacy code that extends the default php exception object. This code prints out a custom HTML error message. I would like to mock this exception object in such a way that when the tested code generates an exception it will just echo the basic message instead of giving me the whole HTML message. I cannot figure out a way to do this. It seems like you can test for explicit exceptions, but you can't change in a general way the behavior of an exception, and you also can't mock up an object that extends a default php functionality. ( can't think of another example of this beyond exceptions... but it would seem to be the case ) I guess the problem is, where would you attach the mocked object?? It seems like you can't interfere with 'throw new' and this is the place that the object method is called.... Or if you could somehow use the existing phpunit exception functionality to change the exception behavior the way you want, in a general way for all your code... but this seems like it would be hacky and bad....

• How can I protect my .NET assemblies from decompilation?

  - by Holli

  One if the first things I learned when I started with C# was the most important one. You can decompile any .NET assembly with Reflector or other tools. Many developers are not aware of this fact and most of them are shocked when I show them their source code. Protection against decompilation is still a difficult task. I am still looking for a fast, easy and secure way to do it. I don't want to obfuscate my code so my method names will be a,b,c or so. Reflector or other tools should be unable to recognize my application as .NET assembly at all. I know about some tools already but they are very expensive. Is there any other way to protect my applications? EDIT: The reason for my question is not to prevent piracy. I only want to stop competitors from reading my code. I know they will and they already did. They even told me so. Maybe I am a bit paranoid but business rivals reading my code doesn't make me feel good.

• C# webservice async callback not getting called on HTTP 407 error.

  - by Ben

  Hi, I am trying to test the use-case of a customer having a proxy with login credentials, trying to use our webservice from our client. If the request is synchronous, my job is easy. Catch the WebException, check for the 407 code, and prompt the user for the login credentials. However, for async requests, I seem to be running into a problem: the callback is never getting called! I ran a wireshark trace and did indeed see that the HTTP 407 error was being passed back, so I am bewildered as to what to do. Here is the code that sets up the callback and starts the request: TravelService.TravelServiceImplService svc = new TravelService.TravelServiceImplService(); svc.Url = svcUrl; svc.CreateEventCompleted += CbkCreateEventCompleted; svc.CreateEventAsync(crReq, req); And the code that was generated when I consumed the WSDL: public void CreateEventAsync(TravelServiceCreateEventRequest CreateEventRequest, object userState) { if ((this.CreateEventOperationCompleted == null)) { this.CreateEventOperationCompleted = new System.Threading.SendOrPostCallback(this.OnCreateEventOperationCompleted); } this.InvokeAsync("CreateEvent", new object[] { CreateEventRequest}, this.CreateEventOperationCompleted, userState); } private void OnCreateEventOperationCompleted(object arg) { if ((this.CreateEventCompleted != null)) { System.Web.Services.Protocols.InvokeCompletedEventArgs invokeArgs = ((System.Web.Services.Protocols.InvokeCompletedEventArgs)(arg)); this.CreateEventCompleted(this, new CreateEventCompletedEventArgs(invokeArgs.Results, invokeArgs.Error, invokeArgs.Cancelled, invokeArgs.UserState)); } } Debugging the WS code, I found that even the SoapHttpClientProtocol.InvokeAsync method was not calling its callback as well. Am I missing some sort of configuration?

• Legitimate uses of the Function constructor

  - by Marcel Korpel

  As repeatedly said, it is considered bad practice to use the Function constructor (also see the ECMAScript Language Specification, 5th edition, § 15.3.2.1): new Function ([arg1[, arg2[, … argN]],] functionBody) (where all arguments are strings containing argument names and the last (or only) string contains the function body). To recapitulate, it is said to be slow, as explained by the Opera team: Each time […] the Function constructor is called on a string representing source code, the script engine must start the machinery that converts the source code to executable code. This is usually expensive for performance – easily a hundred times more expensive than a simple function call, for example. (Mark ‘Tarquin’ Wilton-Jones) Though it's not that bad, according to this post on MDC (I didn't test this myself using the current version of Firefox, though). Crockford adds that [t]he quoting conventions of the language make it very difficult to correctly express a function body as a string. In the string form, early error checking cannot be done. […] And it is wasteful of memory because each function requires its own independent implementation. Another difference is that a function defined by a Function constructor does not inherit any scope other than the global scope (which all functions inherit). (MDC) Apart from this, you have to be attentive to avoid injection of malicious code, when you create a new Function using dynamic contents. Lots of disadvantages and it is intelligible that ECMAScript 5 discourages the use of the Function constructor by throwing an exception when using it in strict mode (§ 13.1). That said, T.J. Crowder says in an answer that [t]here's almost never any need for the similar […] new Function(...), either, again except for some advanced edge cases. So, now I am wondering: what are these “advanced edge cases”? Are there legitimate uses of the Function constructor?

• Django + Virtualenv: manage.py commands fail with ImportError of project name.

  - by Bartek

  This is blowing my mind because it's probably an easy solution, but I can't figure out what could be causing this. So I have a new dev box and am setting everything up. I installed virtualenv, created a new environment for my project under ~/.virtualenvs/projectname Then, I cloned my project from github into my projects directory. Nothing fancy here. There are no .pyc files sitting around so it's a clean slate of code. Then, I activated my virtualenv and installed Django via pip. All looks good so far. Then, I run python manage.py syncdb within my project dir. This is where I get confused: ImportError: No module named projectname So I figured I may have had some references of projectname within my code. So I grep (ack, actually) through my code base and I find nothing of the sorts. So now I'm at a loss, given this environment why am I getting an ImportError on a module named projectname that isn't referenced anywhere in my code? I look forward to a solution .. thanks guys!

• Executing javascript script after ajax-loaded a page - doesn't work

  - by Deukalion

  I'm trying to get a page with AJAX, but when I get that page and it includes Javascript code - it doesn't execute it. Why? Simple code in my ajax page: <script type="text/javascript"> alert("Hello"); </script> ...and it doesn't execute it. I'm trying to use Google Maps API and add markers with AJAX, so whenever I add one I execute a AJAX page that gets the new marker, stores it in a database and should add the marker "dynamically" to the map. But since I can't execute a single javascript function this way, what do I do? Is my functions that I've defined on the page beforehand protected or private? ** UPDATED WITH AJAX FUNCTION ** function ajaxExecute(id, link, query) { if (query != null) { query = query.replace("amp;", ""); } if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else { // code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { if (id != null) { document.getElementById(id).innerHTML=xmlhttp.responseText; } } } if (query == null) { xmlhttp.open("GET",link,true); } else { if (query.substr(0, 1) != "?") { xmlhttp.open("GET",link+"?"+query,true); } else { xmlhttp.open("GET",link+query,true); } } xmlhttp.send(); }

• Switching from form_for to remote_form_for problems with submit changes in Rails

  - by Matthias Günther

  Hi there, another day with Rails and today I want to use Ajax. linkt_remote_link for changing a text was pretty easy so I thought it would also be easy to switch my form_for loop just to an ajax request form with remote_form_for, but the problem with the remote_form_for is that it doesn't save my changes? Here the code that worked: <% form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> Here the code which don't save me the changes and submit them: <% remote_form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post" onsubmit="$.ajax({data:$.param($(this).serializeArray()), dataType:'script', type:'post', url:'/adminbill/update/58'}); return false;"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> I don't know if I have to consider something special when using remote_form_for (see remote_form_for)

• How to prevent linq-to-sql designer undo my changing

  - by anonim.developer

  Dear All, Thanks for your attention in advance, I’ve met an issue with LINQ-2-SQL designer in VS 2008 SP1 which has made me CRAZY. I use Linq2sql as my DAL. It seems Linq2sql speeds up coding in the first step but lots of issues arise in feature specifically with table or object inheritance. In this case I have a class Entity that all other entity classes generated by Linq2sql designer inherit from. public abstract class Entity { public virtual Guid ID { get; protected set; } } public partial class User : monius.Data.Entity { } And the following generated by L2S designer (DataModel.designer.cs) [Column(Storage = "_ID", AutoSync = AutoSync.OnInsert, DbType = "UniqueIdentifier NOT NULL", IsPrimaryKey = true, IsDbGenerated = true, UpdateCheck = UpdateCheck.Never)] [DataMember(Order = 1)] public System.Guid ID { get { return this._ID; } set { if ((this._ID != value)) { this.OnIDChanging(value); this.SendPropertyChanging(); this._ID = value; this.SendPropertyChanged("ID"); this.OnIDChanged(); } } } When I compile the code VS warns me that Warning 1 'User.ID' hides inherited member 'Entity.ID'. To make the current member override that mplementation, add the override keyword. Otherwise add the new keyword. That warning is obvious and I have to change the code generated by L2S designer (DataModel.designer.cs) to […] public override System.Guid ID { … protected set … } And the code compiled with no error or warning and everyone is happy. But that is not the end of story. As soon as I made changes to entities of the diagram (dbml) or even I open dbml file to view it, any change manually I made to designer has been vanished and POOF! Redo AGAIN. That is a painful job. Now I wonder if there is a way to force L2S designer not changing portions of auto-generated code. I’ll be appreciated if someone kindly helps me with this issue.

• RegisterStartupScript not working after upgrading to framework 3.5

  - by AaronS

  I'm trying to upgrade an asp.net c# web project from framework 2.0 to 3.5. When I do this, the client side script that gets written using RegisterStartupScript isn't rendered on the client page. This works perfectly when I compile for 2.0, and for 3.0, but not when I compile for 3.5. Here is the code that isn't getting rendered: Page myPage = (Page)HttpContext.Current.Handler; ScriptManager.RegisterStartupScript(myPage, myPage.GetType(), "alertscript", "alert('test');", true); This is called from a class project, and not the web project itself, which is why I'm using the HttpContext.Current.Handler. There are no errors getting generated from the compiler, the CLR, and there are no client side JavaScript errors. If I do a search for the "alertscript" in my rendered page, the above code actually isn't there. Anyone have ideas as to what is going on? -Edit- This seems to be an issue when I'm trying to register the script from an external project. If I use the exact same code in a class file in the web project (not the code behind), it works. However, if I make a call to a method in a class from another project, it does not work. Does the ScriptManager.RegisterStartupScript not get registered correctly if performed from somewhere besides the web project itself?

• Separating Javascript functions

  - by msharma

  I am wondering how javascripts get included in a jsp - can we put any code which the jsp will recognize and not just javascript code only in the .js file? I have some common javascript code which needs to get executed on different pages, so I decided to place it in its own separate .js file and include it on all jsps which call that function. The js function now refers to a key from a properties file and some other non-javascript code: function openPrivacyStmntWindow(){ var url = <h:outputText escape="false" value="\"#{urls.url_privacyStatement}\";" /> newwindow=window.open(url,'Terms','height=600,width=800,left=300,top=100,scrollbars=1'); newwindow.focus(); return false; } This function worked just fine when it was included in the jsp itself. Now that I have separated it into its own file it doesnt, do I need to include the properties bundle in this file. The value="\"#{urls.url_privacyStatement}\";" is referring to a bundle called "urls" which has a key called "url_privacyStatement" Also in Line 1 var url = <h:outputText escape="false" value="\"#{urls.url_privacyStatement}\";" /> the <h:outputText escape="false" ... /> will it cause any issues? Thanks.

• Simplest way to automatically alter "const" value in Java during compile time

  - by Michael Mao

  Hi all: This is a question corresponds to my uni assignment so I am very sorry to say I cannot adopt any one of the following best practices in a short time -- you know -- assignment is due tomorrow :( link to Best way to alter const in Java on StackOverflow Basically the only task (I hope so) left for me is the performance tuning. I've got a bunch of predefined "const" values in my single-class agent source code like this: //static final values private static final long FT_THRESHOLD = 400; private static final long FT_THRESHOLD_MARGIN = 50; private static final long FT_SMOOTH_PRICE_IDICATOR = 20; private static final long FT_BUY_PRICE_MODIFIER = 0; private static final long FT_LAST_ROUNDS_STARTTIME = 90; private static final long FT_AMOUNT_ADJUST_MODIFIER = 5; private static final long FT_HISTORY_PIRCES_LENGTH = 10; private static final long FT_TRACK_DURATION = 5; private static final int MAX_BED_BID_NUM_PER_AUC = 12; I can definitely alter the values manually and then compile the code to give it another go around. But the execution time for a thorough "statistic analysis" usually requires over 2000 times of execution, which will typically lasts more than half an hour on my own laptop... So I hope there is a way to alter values using other ways than dig into the source code to change the "const" values there, so I can automatically distributed compiled code to other people's PC and let them run the statistic analysis instead. One other reason for a automatically value adjustment is that I can try using my own agent to defeat itself by choosing different "const" values. Although my values are derived from previous history and statistical results, they are far from the most optimized values. I hope there is a easy way so I can quickly adopt that so to have a good sleep tonight while the computer does everything for me... :) Any hints on this sort of stuff? Any suggestion is welcomed and much appreciated.

• Conditional "Get Script File" in Javascript without using a library function

  - by Adam

  I work at a company that has many clients that have their own website that "plugs in" to our system. In other words they have their own website and they have a link that, when the user clicks it, transitions them over to our site. There is a feature that I want to track by giving the client a small block of code to put on their homepage. Whenever the homepage is loaded with a certain query string variable I want the block of code to request a file on my server. Then on the server I'll record the tracking info based on the query string. All this would be really easy if I can guarantee that the client would be using jQuery or some similar library, but there are a lot of clients and I can't really rely on them all using jQuery. At the same time I'd like to limit the size of the block of javascript code that they paste in. I think the best solution would be to have something like: if(querystring.substring("Tracking=") > 0) { include("blah.aspx?TrackingQS=" + querystring); } but I can't find a include function in built-in javascript without calling some library like jQuery. Any thoughts?? I could do straight up AJAX but I want to limit the number of lines of code for several reasons that I won't bore you with here.

• how to enable iFrame designMode in a local webpage without using the localhost server?

  - by vjk2005

  The code... <html> <body> <iframe id="editableFrame"></iframe> <script type="text/javascript"> editableFrame.document.designMode="on"; </script> </body> </html> gets the iFrame editable only when run off a server(http://...)(online or from localhost). How do I get this working by simply opening it up as a local html file(file:///...) in the browser? Some browser specific notes: 1. Firefox needs slightly different code to enable designMode but the problem still remains. 2. IE8 gets me the behavior I want with this code, but it pops up a warning about enabling ActiveX controls which the user must accept before getting the iFrame editable. 3. Opera 10.5 is the only browser that has the behavior I want... iFrames are editable without needing to run the code off a server.

• How to have a where clause on an insert or an update in Linq to Sql?

  - by Kelsey

  I am trying to convert the following stored proc to a LinqToSql call (this is a simplied version of the SQL): INSERT INTO [MyTable] ([Name], [Value]) SELECT @name, @value WHERE NOT EXISTS(SELECT [Value] FROM [MyTable] WHERE [Value] = @value) The DB does not have a constraint on the field that is getting checked for so in this specific case the check needs to be made manually. Also there are many items constantly being inserted as well so I need to make sure that when this specific insert happens there is no dupe of the value field. My first hunch is to do the following: using (TransactionScope scope = new TransactionScope()) { if (Context.MyTables.SingleOrDefault(t => t.Value == in.Value) != null) { MyLinqModels.MyTable t = new MyLinqModels.MyTable() { Name = in.Name, Value = in.Value }; // Do some stuff in the transaction scope.Complete(); } } This is the first time I have really run into this scenario so I want to make sure I am going about it the right way. Does this seem correct or can anyone suggest a better way of going about it without having two seperate calls? Edit: I am running into a similar issue with an update: UPDATE [AnotherTable] SET [Code] = @code WHERE [ID] = @id AND [Code] IS NULL How would I do the same check with Linqtosql? I assume I need to do a get and then set all the values and submit but what if someone updates [Code] to something other than null from the time I do the get to when the update executes? Same problem as the insert...

• How to query AD to get name email from lan id

  - by Kumar

  I have some code in asp.net ( kindly given by someone else ) to query AD to get user name and email etc. using System.DirectoryServices; using System.DirectoryServices.ActiveDirectory; using ActiveDs; DirectorySearcher search = new DirectorySearcher(new DirectoryEntry(), string.Format("(samaccountname={0})", id)); if (search == null) return id; if (search.FindOne() == null) return id; DirectoryEntry usr = search.FindOne().GetDirectoryEntry(); IADsUser oUsr = (IADsUser)usr.NativeObject; return string.Format("{0} {1}", usr.Properties["givenname"].Value, usr.Properties["sn"].Value); However this requires impersonation with an id that's required to be changed every 2 weeks and then updated in the web.config which is often forgotten Is there any non impersonation code to achieve the same result ? UPDATE - it's a config tool and it looks up name, email id etc. I like the service a/c idea Q - How is it possible to run ( impersonate ) just the AD code with a "service" a/c ? any samples/code ? how do you impersona

• Destructors not called when native (C++) exception propagates to CLR component

  - by Phil Nash

  We have a large body of native C++ code, compliled into DLLs. Then we have a couple of dlls containing C++/CLI proxy code to wrap the C++ interfaces. On top of that we have C# code calling into the C++/CLI wrappers. Standard stuff, so far. But we have a lot of cases where native C++ exceptions are allowed to propagate to the .Net world and we rely on .Net's ability to wrap these as System.Exception objects and for the most part this works fine. However we have been finding that destructors of objects in scope at the point of the throw are not being invoked when the exception propagates! After some research we found that this is a fairly well known issue. However the solutions/ workarounds seem less consistent. We did find that if the native code is compiled with /EHa instead of /EHsc the issue disappears (at least in our test case it did). However we would much prefer to use /EHsc as we translate SEH exceptions to C++ exceptions ourselves and we would rather allow the compiler more scope for optimisation. Are there any other workarounds for this issue - other than wrapping every call across the native-managed boundary in a (native) try-catch-throw (in addition to the C++/CLI layer)?

• Shell script task status monitoring

  - by Bikram Agarwal

  I'm running an ANT task in background and checking in 60 second intervals whether that task is complete or not. If it is not, every 60 seconds, a message should be displayed on screen - "Deploy process is still running. $slept seconds since deploy started", where $slept is 60, 120, 180 n so on. There's a limit of 1200 seconds, after which the script will show the log via 'ant log' command and ask the user whether to continue. If the user chooses to continue, 300 seconds are added to the time limit and the process repeats. The code that I am using for this task is - ant deploy & limit=1200 deploy_check() { while [ ${slept:-0} -le $limit ]; do sleep 60 && slept=`expr ${slept:-0} + 60` if [ $$ = "`ps -o ppid= -p $!`" ]; then echo "Deploy process is still running. $slept seconds since deploy started." else wait $! && echo "Application ${New_App_Name} deployed successfully" || echo "Deployment of ${New_App_Name} failed" break fi done } deploy_check if [ $$ = "`ps -o ppid= -p $!`" ]; then echo "Deploy process did not finish in $slept seconds. Here's the log." ant log echo "Do you want to kill the process? Press Ctrl+C to kill. Press Enter to continue." read log limit=`expr ${limit} + 300` deploy_check fi Now, the problem is - this code is not working. This looks like a perfectly good code and yet, this is not working. Can anyone point out what is wrong with this code, please.

• Returning a variable in a public void...

  - by James Rattray

  Hello, I'm abit new to programming Android App's, however I have come across a problem, I can't find a way to make global variables -unlike other coding like php or VB.NET, are global variables possible? If not can someone find a way (and if possible implement the way into the code I will provide below) to get a value from the variable 'songtoplay' so I can use in another Public Void... Here is the code: final Spinner hubSpinner = (Spinner) findViewById(R.id.myspinner); ArrayAdapter adapter = ArrayAdapter.createFromResource( this, R.array.colours, android.R.layout.simple_spinner_item); adapter .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); hubSpinner.setAdapter(adapter); // hubSpinner.setOnItemSelectedListener(new OnItemSelectedListener() { public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { //code Object ttestt = hubSpinner.getSelectedItem(); final String test2 = ttestt.toString(); Toast message1 = Toast.makeText(Textbox.this, test2, Toast.LENGTH_LONG); message1.show(); String songtoplay = test2; // Need songtoplay to be available in another 'Public Void' } public void onNothingSelected(AdapterView<?> parentView) { //Code } }); Basically, it gets the value from the Spinner 'hubSpinner' and displays it in a Toast. I then want it to return a value for string variable 'songtoplay' -or find a way to make it global or useable in another Public Void, (Which is will a button, -loading the song to be played) Please help me, Thanks alot.

• ASP.NET MVC jQuery autocomplete with url.action helper in a script included in a page.

  - by Boob

  I have been building my first ASP.NET MVC web app. I have been using the jQuery autocomplete widget in a number of places like this: <head> $("#model").autocomplete({ source: '<%= Url.Action("Model", "AutoComplete") %>' }); </head> The thing is I have this jQuery code in a number of different places through my web app. So i thought I would create a seperate javascript script (script.js) where I could put this code and then just include it in the master page. Then i can put all these repeated pieces of code in that script and just call them where I need too. So I did this. My code is shown below: In the site.js script I put this function: function doAutoComplete() { $("#model").autocomplete({ source: '<%= Url.Action("Model", "AutoComplete") %>' }); } On the page I have: <head> <script src="../../Scripts/site.js" type="text/javascript"></script> doAutoComplete(); </head> But when I do this I get an Invalid Argument exception and the autocomplete doesnt work. What am I doing wrong? Any ideas?Do i need to pass something to the doAutoComplete function?

• injection attack (I thought I was protected!) <?php /**/eval(base64_decode( everywhere

  - by Cyprus106

  I've got a fully custom PHP site with a lot of database calls. I just got injection hacked. This little chunk of code below showed up in dozens of my PHP pages. <?php /**/ eval(base64_decode(big string of code.... I've been pretty careful about my SQL calls and such; they're all in this format: $query = sprintf("UPDATE Sales SET `Shipped`='1', `Tracking_Number`='%s' WHERE ID='%s' LIMIT 1 ;", mysql_real_escape_string($trackNo), mysql_real_escape_string($id)); $result = mysql_query($query); mysql_close(); For the record, I rarely use mysql_close() at the end though. That just happened to be the code I grabbed. I can't think of any places where I don't use mysql_real_escape_string(), (although I'm sure there's probably a couple. I'll be grepping soon to find out) There's also no places where users can put in custom HTML or anything. In fact, most of the user-accessible pages, if they use SQL calls at all, are almost inevitably "SELECT * FROM" pages that use a GET or POST, depending. Obviously I need to beef up my security, but I've never had an attack like this and I'm not positive what I should do. I've decided to put limits on all my inputs and go through looking to see if i missed a mysql_real_escape_string somewhere... Anybody else have any suggestions? Also... what does this type of code do? Why is it there?

• Processing XML form input in ASP

  - by Omar Kooheji

  I'm maintaining a legacy application which consists of some ASP.Net pages with c# code behinds and some asp pages. I need to change the way the application accepts it's input from reading a set of parameters from some form fields to reading in one form field which contains contains some XML and parsing to get the parameters out. I've written a C# class that takes an The NameValueCollection from the C# HttpRequest's Form Element. Like so NameValueCollection form = Request.Form; Dictionary<string, string> fieldDictionary = RequestDataExtractor.BuildFieldDictionary(form); The code in the class looks for a particular parameter and if it's there processes the XML and outputs a Dictionary, if its not there it just cycles through the Form parameters and puts them all into the dictionary (Allowing the old method to still work) How would I do this in ASP? Can I use my same class, or a modified version of it? or do I have to write some new code to get this working? If I have to write ASP code Whats the best way to process the XML in ASP? Sorry if this seems like a stupid question but I know next to nothing about ASP and VB.

• jQuery .html not writing span on page load, rights the span on ajax response

  - by pedalpete

  I've got a bit of a calendar I'm building with events that go beyond the boundary of one day. I've got a graph which shows how many events are running concurrently. In order to graph out the events which go into another day, I look for hours24, and run an extra bit of code. jQuery('li#hour'+placeGroup+'_'+schedDay2+'_'+thisHour,nextDay).data('count', numStaff).html(''+printHour+''+numEvents+' scheduled').css('height',numEvents*5+'px'); The code is working, the li items are being found, proper height is the css is being applied, data is set, which I've checked by running alert(jQuery('li#hour'+placeGroup+'_'+schedDay2+'_'+thisHour,nextDay).data('count')); right after the pervious bit of code. The only thing that isn't being done is the .html(add span) stuff. I run this code in two places. Once when the page loads, and once when an action is taken which changes the number of events via an ajax response. The li DOM object I'm writting to is created before the script is run, and the height is being applied, but not the span, and only on page load. Any ideas on this one? I'm stumped.
