Trying to parse xml, but xmldocument.loadxml() is trying to download?

- by maxp

I have a string input that i do not know whether or not is valid xml. I think the simplest aprroach is to wrap new XmlDocument().LoadXml(strINPUT); In a try/catch. The problem im facing is, sometimes strINPUT is an html file, if the header of this file contains <!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""> <html xml:lang=""en-GB"" xmlns=""http://www.w3.org/1999/xhtml"" lang=""en-GB""> ...like many do, it actually tries to make a connection to the w3.org url, which i really dont want it doing. Anyone know if its possible to just parse the string without trying to be clever and checking external urls? Failing that is there an alternative to xmldocument?

Will the URL /nosuchpage get routed via my ASP.NET MVC application?

- by Gary McGill

[I'm trying to figure out the reason why I'm having another problem, and this question is part of the puzzle.] I have an MVC 2 website that has routing set up so that URLs such as /Customer/23/Order/47 get handled by various controllers. I do not have a rule that would match, for example, /nosuchpage and in my Cassini environment a request for that URL will trigger my Application_Error code, which lets me log the error and show a friendly response. However, when I deployed this website on IIS7 using integrated mode, my Application_Error is not triggered, and IIS shows its own 404 message. No matter what I've tried, I can't get Application_Error to fire. Now I'm thinking: is the reason it doesn't fire because the request is not getting routed via my application? Either because I didn't explicitly set up a catch-all route, or because the file-extension fools it into thinking it should use the "static file handler" (whatever that is)? Should I expect my Application_Error to be invoked?

How to make video in Java captured from webcam through lti-Civil CaptureDeviceStream ?

- by i.Psi

Can I do it only with the lti-Civil classes or I need FMJ or JMF ? do I use the actual Stream or set of captured Images from CaptureObserver? Thanks. captureStream = system.openCaptureDeviceStream(info.getDeviceID()); captureStream.setObserver(new CaptureObserver(){ public void onError(CaptureStream arg0, CaptureException arg1) { } public void onNewImage(CaptureStream streamSource, Image image) { try { imageFrame.setImage(AWTImageConverter.toBufferedImage(image)); bufferedImage = AWTImageConverter.toBufferedImage(image); } catch (Throwable t) { t.printStackTrace(); } } }); captureStream.start();

Sharing Jinja2 templates between Pylons and Django applications

- by Joe Holloway

I'm writing a couple of Jinja2 templates that basically implement some common grid layouts. I'd like to be able to share this 'library' of templates between a Pylons app and Django app. I've hit a minor stumbling block in that Django's template context is accessible from the "top-level" of the template, whereas Pylons wraps your context inside the thread local c (or tmpl_context) variable. Here are some analogous examples that demonstrate this. Django from django.shortcuts import render_to_response ctx = {} ctx['name'] = 'John' return render_to_response('hello.html', ctx) hello.html: Hello {{ name }} Pylons from pylons import tmpl_context as c from myapp.lib.base import render c.name = 'John' return render('hello.html') hello.html: Hello {{ c.name }} What I'm trying to do is make it so that hello.html is the same across both frameworks. One way I see to do it is by wrapping the Django render_to_response and do something like this: ctx['c'] = ctx But that just doesn't feel right. Anybody see other alternatives to this? Thanks

C#: Check if administrator has write access to a file

- by Bilal Aslam

The Problem: I need to check if a user (local user or domain user, either one is possible) has write access to a file (if you're curious, %windir%\system32\inetsrv\applicationHost.config. This file is protected by Windows and you need to be an administrator to write to it.) My Solution: The general construct is: using (Impersonator impersonator = new Impersonator(domain, username, password)) { try { using (FileStream fs = File.OpenWrite(appHostConfigPath)) { return true; } catch { return false; } } As you can imagine, the Impersonator class is an IDisposible which uses native interop to call LogonUser. Nothing too creative, and it works. Where I am stuck: On Windows OSs with UAC enabled, this function always return false even if the user specified by username is an administrator. Even though my program is running elevated as an administrator, I suspect what's happening is that the impersonated code is running as a limited administrator. Hence, the method is returning false. I don't have any creative solutions to this. Can anyone help?

Mysql: ROLLBACK for multiple queries

- by Raj

Hi I have more than three MySql queiries in a PHP script triggered by scheduled task. If a query catch an error, script throw an exception and rollback that Mysql query. It works fine. However if first query works fine, but not 2nd query, throw an exception, it rollback 2nd one but not 1st query. I am using begin_trans(), commit and rollback() for individual queries because Sometimes i need to rollback one query, sometimes all queries. Is there any way to rollback one query or all queries? Thanks in advance UPDATE: I got it working, there was no problem with in begin_trans(), commit and rollback(), the database connection config was different for one query from other queries, crazy code without any comments!!!

This regx does not work only in Chrome

- by Deeptechtons

Hi i just put up a validation function in jScript to validate filename in fileupload control[input type file]. The function seems to work fine in FF and sometimes in ie but never in Chrome. Basically the function tests if File name is atleast 1 char upto 25 characters long.Contains only valid characters,numbers [no spaces] and are of file types in the list. Could you throw some light on this function validate(Uploadelem) { var objRgx = new RegExp(/^[\w]{1,25}\.*\.(jpg|gif|png|jpeg|doc|docx|pdf|txt|rtf)$/); objRgx.ignoreCase = true; if (objRgx.test(Uploadelem.value)) { document.getElementById('moreUploadsLink').style.display = 'block'; } else { document.getElementById('moreUploadsLink').style.display = 'none'; } }

Looping through list items with jquery

- by Gallen

I have this block of code listItems = $("#productList").find("li"); for (var li in listItems) { var product = $(li); var productid = product.children(".productId").val(); var productPrice = product.find(".productPrice").val(); var productMSRP = product.find(".productMSRP").val(); totalItemsHidden.val(parseInt(totalItemsHidden.val(), 10) + 1); subtotalHidden.val(parseFloat(subtotalHidden.val()) + parseFloat(productMSRP)); savingsHidden.val(parseFloat(savingsHidden.val()) + parseFloat(productMSRP - productPrice)); totalHidden.val(parseFloat(totalHidden.val()) + parseFloat(productPrice)); } and I'm not getting the desired results - totalItems is coming out as 180+ and the rest all NaN. I suspect its where i use var product = $(li); or perhaps with the expression on the loop itself. Either way - I need to loop through the <li> items in the <ul> labelled #productList

Finding an open and closing tag in Regexp

- by Rixius

Is there a way to find custom tags in regexp I.e. match {a}sometext{/a} As well as {c=#fff}sometext{/c} So that it finds the entire block of inner content? The problem is the sometext could have another tag as in: {a=http://www.google.com}{b}Hello, world{/b}{/a} The only solutions I can come up with would match from {a... to .../b} when I want {a... to .../a} is there a single regexp solution, or would it be best to match the start, and then use another method to find the end from the back up, and grab it out that way? I'm using PHP 5.2 so I have all the options that entails.

How can I perform a web query in C# similar to the Data > Import External Data > New Web Query in Mi

- by TNT

I need to pull data from a table on a website. I can easily do this in VBA using the Web Query, but I need to do this in C#. I'm just having some trouble figuring out how to properly convert the code. I got something close, but it's returning HTML with the data. I just want the data. Any help would be great. The block of code giving me issues is below: Private Function GetData(ByVal theURL As String, ByVal theRow As Integer, ByVal thePosition As Integer, ByVal theColumn As String, ByVal theTable As Integer) With ActiveSheet.QueryTables.Add(Connection:="URL;" + theURL, Destination:=Sheet2.Range(theColumn & theRow + 1)) .Name = "op?s=" + Mid(theURL, thePosition + 1) + "_1" .PreserveFormatting = True .AdjustColumnWidth = True .WebTables = theTable .Refresh BackgroundQuery:=False End With End Function

Running a program in another one?

- by Roman

Hi, I've written a program in C++. It's just using the console to have it as portable as possible. Unfortunately, many Windows-Users seem not to understand how to use the program (Linux Users are just fine with it :) ). So I'd like to write a GUI for that program. As this needs to run on Windows only, I'd like to write it in C#. But I want to maintain the GUI apart from the original program. So basically, I need a way to include a compiled *.exe into another program. Is there a way to catch the console output from another program and send inputs to it? Also, can the console of the original program be hidden? Similar Questions How To: Execute command line in C#, get STD OUT results

Simulating C-style for loops in python

- by YGA

(even the title of this is going to cause flames, I realize) Python made the deliberate design choice to have the for loop use explicit iterables, with the benefit of considerably simplified code in most cases. However, sometimes it is quite a pain to construct an iterable if your test case and update function are complicated, and so I find myself writing the following while loops: val = START_VAL while <awkward/complicated test case>: # do stuff ... val = <awkward/complicated update> The problem with this is that the update is at the bottom of the while block, meaning that if I want to have a continue embedded somewhere in it I have to: use duplicate code for the complicated/awkard update, AND run the risk of forgetting it and having my code infinite loop I could go the route of hand-rolling a complicated iterator: def complicated_iterator(val): while <awkward/complicated test case>: yeild val val = <awkward/complicated update> for val in complicated_iterator(start_val): if <random check>: continue # no issues here # do stuff This strikes me as waaaaay too verbose and complicated. Do folks in stack overflow have a simpler suggestion?

Catching Oracle Errors in Django

- by Dashdrum

My Django app runs on an Oracle database. A few times a year, the database is unavailable because of a scheduled process or unplanned downtime. However, I can't see how to catch the error a give a useful message back to the requester. Instead, a 500 error is triggered, and I get an email (or hundreds) showing the exception. One example is: File "/opt/UDO/env/events/lib/python2.6/site-packages/django/db/backends/oracle/base.py", line 447, in _cursor self.connection = Database.connect(conn_string, **conn_params) DatabaseError: ORA-01035: ORACLE only available to users with RESTRICTED SESSION privilege I see a similar error with a different ORA number when the DB is down. Because the exception is thrown deep within the Django libraries, and can be triggered by any of my views or the built in admin views, I don't know where any exception trapping code would go. Any suggestions?

how to manually add a cookie to Mechanize state?

- by fearless_fool

[I'm working in Ruby, but my question is valid for other languages as well.] I have a Mechanize-driven application. The server I'm talking to sets a cookie using javascript (rather than standard set-cookie), so Mechanize doesn't catch the cookie. I need to pass that cookie back on the next GET request. The good news is that I already know the value of the cookie, but I don't know how to tell Mechanize to include it in my next GET request. Pointers or suggestions are welcome. Thanks in advance. -ff

No events are fired from an imagebrush via ImageOpened/ImageFailed

- by umlgorithm

A canvas is received from the server, and an image brush is extracted from the canvas via searching for a bunch of pathes. In summary, Canvas - Path - Path.Fill - ImageBrush. Now, I want to take a snapshot of the ImageBrush using WriteableBitmap when it is loaded and here is what I did var imageBrushes = VisualTreeUtility.FindVisualChildren<Path>(canvas) .Where(i => i.Fill.GetType() == typeof(ImageBrush)) .Select(p => p.Fill); foreach(var image in imageBrushes) { image.ImageOpened += delegate { //never gets here }; image.ImageFailed += delegate { //never gets here either }; // if the image is already loaded if (((BitmapSource)image.ImageSource).PixelWidth != 0) { // never gets here either } } As you can see the comments in the code above, no matter what I try, I can't seem to catch an event from the image. Any suggestions?

Good portfolio projects

- by David

Hi, I am a recent graduate and am looking to start a career in web development. Its kind of a catch 22 at the moment as I have a fair bit of programming experience from university but not really in web development and to get a job in web development a portfolio is typically required. So, I am looking to start a building a few application in order to have something to show potential employers. Im more into the backend stuff although am just as comfortable with front end development. Does anyone have any thoughts on some potential projects that would be both relatively quick (as i need to get a job soon!) to build but show off enough programming knowlege / skills to be impressive to employers. At the moment i am also learning to use the zend framework and I would hope to find work using such a framework (mvc). My initial thoughts would be things like a webmail app or maybe a custom CMS. Any ideas would be greatley appreciated.

LINQ to SQL: On load processing of lazy loaded associations

- by Matt Holmes

If I have an object that lazy loads an association with very large objects, is there a way I can do processing at the time the lazy load occurs? I thought I could use AssociateWith or LoadWith from DataLoadOptions, but there are very, very specific restrictions on what you can do in those. Basically I need to be notified when an EntitySet< decides it's time to load the associated object, so I can catch that event and do some processing on the loaded object. I don't want to simply walk through the EntitySet when I load the parent object, because that will force all the lazy loaded items to load (defeating the purpose of lazy loading entirely).

Heap corruption detected error when attempting to free pointer

- by AndyGeek

Hi, I'm pretty new to C++ and have run into a problem which I have not been able to solve. I'm trying to convert a System::String to a wchar_t pointer that I can keep for longer than the scope of the function. Once I'm finished with it, I want to clean it up properly. Here is my code: static wchar_t* g_msg; int TestConvert() { pin_ptr<const wchar_t> wchptr = PtrToStringChars("Test"); g_msg = (wchar_t*)realloc(g_msg, wcslen(wchptr) + 1); wcscpy(g_msg, wchptr); free (g_msg); // Will be called from a different method } When the free is called, I'm getting "HEAP CORRUPTION DETECTED: after Normal block (#137) at 0x02198F90." Why would I be getting this error? Andrew L

How do you go from an abstract project description to actual code?

- by Jason

Maybe its because I've been coding around two semesters now, but the major stumbling block that I'm having at this point is converting the professor's project description and requirements to actual code. Since I'm currently in Algorithms 101, I basically do a bottom-up process, starting with a blank whiteboard and draw out the object and method interactions, then translate that into classes and code. But now the prof has tossed interfaces and abstract classes into the mix. Intellectually, I can recognize how they work, but am stubbing my toes figuring out how to use these new tools with the current project (simulating a web server). In my professors own words, mapping the abstract description to Java code is the real trick. So what steps are best used to go from English (or whatever your language is) to computer code? How do you decide where and when to create an interface, or use an abstract class?

How to correctly open WCF service

- by Sergej Andrejev

Hi there, I'm using WCF client like this... var client = new TestClient(); try { response = service.Operation(request); } finally { try { if (client.State != CommunicationState.Faulted) client.Close(); } catch (Exception) { client.Abort(); } } but from time to time I get 500 HTTP error which is the only answer I get for next 15 minutes, then everything is back to normal for 15 minutes and so on. I know there is some load balancing stuff going on service side but guys there can't find any problems with it. That's why I started wondering am I using WCF service correctly. I already made a mistake once when I was using "using" to close service connection and I'm afraid I doing something wrong again. So can anybody say whether my way of calling WCF service is correct or not in all (event the most rare) circumstances?

Synchronisation construct inside pragma for

- by Sayan Ghosh

Hi, I have a program block like: for (iIndex1=0; iIndex1 < iSize; iIndex1++) { for (iIndex2=iIndex1+1; iIndex2 < iSize; iIndex2++) { iCount++; fDist =(*this)[iIndex1].distance( (*this)[iIndex2] ); m_oPDF.addPairDistance( fDist ); if ((bShowProgress) && (iCount % 1000000 == 0)) xyz_exception::ui()->progress( iCount, (size()-1)*((size()-1))/2 ); } } } } I have tried parallelising the inner and outer loop and by putting iCount in a critical region. What would be the best approach to parallelise this? If I wrap iCount with omp single or omp atomic then the code gives an error and I figured out that would be invalid inside omp for. I guess I am adding many extraneous stuffs to paralellise this. Need some advice... Thanks, Sayan
