• Preventing cross-site scripting in ASP.NET MVC - using jQuery or standard HtmlHelpers

  - by user313353

  I am building an ASP.NET MVC application that is AJAX-driven. For some reason I need to add some DOM elements on the fly when clicking a submit button. This is accomplished with jQuery.append(). One element inserted is a textarea, whose the data must be parse before submitting to ensure that no cross-site scripting can be done. We know that the Html.Encode() works great but must be declared outside a script tag. All I have done with jQuery is embedded within a script tag. 1) Is there a way to take advantage of the Html.Encode() within a script tag? 2) How can I accomplish this with jQuery? At worst I can use HttpUtility.HtmlEncode(), which is called on the server-side. Thanks for your help. Roland

• reading binary code of a file...in PHP

  - by Val

  How can I read the binary code(to get the 1s and 0s) of a file. $filename = "something.mp3"; $handle = fopen($filename, "rb"); $contents = fread($handle, filesize($filename)); fclose($handle); I tried this but it shows some strange characters... i presume that this is the formated binary...? I was hoping to get the 1's and 0's instead.... also i am not looking only .mp3 files it could be anything .e.g: .txt , .doc , .mp4, .php .jpg,.png etc.... Thanks

• How to handle Many-To-Many In Grails without belongsTo?

  - by nute

  I need to create a many-to-many relationship in Grails. I have a "Question" domain and a "Tag" domain. A Question can have 0 or more tags. A Tag can have 0 or more Questions. If I put a "hasMany" on each sides, it gives me an error saying I need a "belongTo" somewhere. However, adding a belongsTo means that the owner must exist... Like I said, a Tag could have 0 questions, and a Question could have 0 tags. There is no concept of an owner, it's a many-to-many! What am I supposed to do?

• VLC helper protocol on Mac OS X

  - by Preben

  Hey everybody, I am trying to add a vlc:// helper protocol on Mac OS X. To register the protocol, I have unsuccessfully been playing around with the MoreInternet PrefPane. What I want to have in my browser is a vlc://someressource.com/audio.mp3, which should launch VLC and add http://someressource.com/audio.mp3 to the playlist (this works fine on Windows and also Linux if I remember correctly). Maybe even just have vlc://http:// so that https would also be supported. I have no idea how to achieve this. I tried making a bash script, which MoreInternet would not accept. Then I tried making an application through Automator with my Bash script embedded. That did not work either, as the Automator application has no "creator code" - whatever that is?! Can any of you guys point me in the right direction? Thanks in advance!

• NHibernate Linq - Duplicate Records

  - by adegiamb

  I am having a problem with duplicate blog post coming back when i run the linq statement below. The issue that a blog post can have the same tag more then once and that's causing the problem. I know when you use criteria you can do the followingcriteria.SetResultTransformer(new DistinctRootEntityResultTransformer()); How can I do the same thing with linq? List<BlogPost> result = (from blogPost in _session.Linq<BlogPost>() from tags in blogPost.Tags where tags.Tag == tag && blogPost.IsPublished && blogPost.Slug != slugToExclude orderby blogPost.DateCreated descending select blogPost).Distinct() .Skip(recordsToSkip).Take(pageSize).ToList();

• SQL to get range of results in alphabetical order

  - by Tom Gullen

  I have a table, tblTags which works in much the same way as StackOverflows tagging system. When I view a tags page, let's say the tag Tutorial I want to display the 10 tags before and after it in alphabetical order. So if we are given the tag Tutorial of ID 30 how can we return a record set in the order resembling: Tap Tart > Tutorial Umbrellas Unicorns Xylaphones I have thought of ways of doing this, badly, in my opinion as they involve retrieving ugly amounts of data. I'm not sure if it's possible to do something along the lines of (pseudo): SELECT RANGE(0 - 30) FROM tblTags ORDER BY Name ASC But how do you know the position of the tutorial tag in the list in an efficient manner without traversing the entire list until you find it? I'm using SQL Server 2008 R2 Express with LINQ if it makes any difference, SQL queries or LINQ would be great answers, thanks!

• python streaming TCP server with RPC

  - by Noah

  I have written a little streaming mp3 server in python. So far all it does is accept a ServerSocket connection, and begin streaming all mp3 data in its queue to the request using socket.send(). I have implemented this to chunk in stream icy metadata, so the name of the playing song shows up in the client. I would like to add playlist management to the server, so that I can manipulate the playlist of the running server. I have a vague idea that xmlrpclib would be suited to doing this, but I'm confused about one thing: When I start the server it listens on port N. The python xmlrpclib examples involve creating a socket and listening for requests. So my question is should server listen on two ports; i.e., one for streaming client requests and one for xmlrpclib calls, or is there a way to do it by somehow delegating the request to the appropriate handler based on its type?

• UILabels text disappears when animating

  - by Wilhelm Michaelsen

  I have this code: - (void)my_button_tapped { if (my_button.tag == 0) { [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.5]; my_label.frame = CGRectMake(450, 455, 200, 20); [UIView commitAnimations]; [my_button setBackgroundImage:[UIImage imageNamed:@"check.png"] forState:UIControlStateNormal]; my_button.tag = 1; } else { [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.5]; my_label.frame = CGRectMake(450, 455, 0, 20); [UIView commitAnimations]; [my_button setBackgroundImage:nil forState:UIControlStateNormal]; my_button.tag = 0; } } When I tap my_button first time the label is expanded into 200px width, when I press the button again the label decreases to 0px width but immediately at button press the text disappears. What's wrong?

• Runtime Error in asp.net site?

  hi, I developed a website in asp.net and i place the site in online. I upload my site in online by using CuteFTP. After uploading when i type my url it is giving error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

• html/php: how to handle absolute url's?

  - by YuriKolovsky

  Is the html tag safe to use in terms of browser support? Or should I generate a root path with PHP which i then add like this <a href="<?=BASE?>somepage.html">somepage</a> which makes up a absolute url. using the base tag like this <base href="<?=BASE?>" /> I am then able to use links like this <a href="somepage.html">somepage</a> now I am fully aware that it would be much easier to just do this without using the base tag: <a href="/somepage.html">somepage</a> but how do I test locally then with a base url of http://localhost/testsite/ ???

• PHP Check if <ul> has ended IF it exists

  I have my blog generate a preview by taking the first 300 characters and cut off the last whole word. My problem is, when I have a list near the top of the blog it is sometimes included in the preview, however the end list tag usually never is. So how can I check the $preview variable for a starting list tag, and if it is found, check for an ending tag and if it's not there add one. All the code for my preview. $preview = wordwrap($content, 300); $preview = explode("\n", $preview); $preview = $preview[0] . "...";

• how to save state of dynamically created editTexts

  - by user922531

  I'm stuck at how to save the state of my EditTexts on screen orientation. Currently if text is inputted into the EditTexts and the screen is orientated, the fields are wiped (as expected). I am already calling onSaveInstanceState and saving a String, but I have no clue on how to save the EditTexts which are created in code and then retrieve them and add them to the EditTexts when redrawing the activity. Snippet of my code: My main activity is as follows: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // get the multidim array b = getIntent().getBundleExtra("obj"); m = (Methods) b.getSerializable("Methods"); // method to draw the layout InitialiseUI(); // Restore UI state from the savedInstanceState. if (savedInstanceState != null) { String strValue = savedInstanceState.getString("light"); if (strValue != null) { FLight = strValue; } } try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** Called when the back button is pressed. */ @Override public void onResume() { super.onResume(); try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** saves data before leaving the screen */ @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("light", FLight); } /** called when exiting / leaving the screen */ @Override protected void onPause() { super.onPause(); Log.d(TAG, "onPause()"); if (mCamera != null) { mCamera.stopPreview(); mCamera.release(); mCamera = null; } } /* * set up the UI elements - add click listeners to buttons used in * onCreate() and onConfigurationChanged() * * Set the editTexts fields to show the previous readings as Hints */ public void InitialiseUI() { Log.d(TAG, "Start of InitialiseUI, Main activity"); // get a reference to the TableLayout final TableLayout myTLreads = (TableLayout) findViewById(R.id.myTLreads); // Create arrays to hold the TVs and ETs final TextView[] myTextViews = new TextView[m.getNoRows()]; // create an empty array; final EditText[] myEditTexts = new EditText[m.getNoRows()]; // create an empty array; for(int i =0; i<=m.getNoRows()-1;i++ ){ TableRow tr=new TableRow(this); tr.setLayoutParams(new LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); // create a new textview / editText final TextView rowTextView = new TextView(this); final EditText rowEditText = new EditText(this); // setWidth is needed otherwise my landscape layout is OFF rowEditText.setWidth(400); // this stops the keyboard taking up the whole screen in landscape layout rowEditText.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI); // add some padding to the right of the TV rowTextView.setPadding(0,0,10,0); // set colors to white rowTextView.setTextColor(Color.parseColor("#FFFFFF")); rowEditText.setTextColor(Color.parseColor("#FFFFFF")); // if readings already sent today set color to yellow if(m.getTransmit(i+1)==false){ rowEditText.setEnabled(false); rowEditText.setHintTextColor(Color.parseColor("#FFFF00")); } // set the text of the TV to the meter name rowTextView.setText(m.getMeterName(i+1)); // set the hint of the ET to the last submitted reading rowEditText.setHint(m.getLastReadString(i+1)); // add the textview to the linearlayout rowEditText.setInputType(InputType.TYPE_CLASS_PHONE);//InputType.TYPE_NUMBER_FLAG_DECIMAL); tr.addView(rowTextView); tr.addView(rowEditText); myTLreads.addView(tr); // add a reference to the textView myTextViews[i] = rowTextView; myEditTexts[i] = rowEditText; } final Button submit = (Button) findViewById(R.id.submitReadings); // add a click listener to the button try { submit.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Log.d(TAG, "Submit button clicked, Main activity"); preSubmitCheck(m.getAccNo(), m.getPostCode(), myEditTexts); // method to do HTML getting and sending } }); } catch (Exception e) { Log.d(TAG, "Exceptions (submit button)" + e.toString()); } }// end of InitialiseUI I don't need to do anything with these values until a button is clicked. Would it be easier if they were a ListView, i'm guessing I would still have the problem of saving them and retrieving them on rotation. If it helps I have an object m which is a string[][] I could temporarily somehow store them in

• How do I reference the other object in django models

  - by UserZero

  Hi, first post here.In Django, I want to have many files be associated with a particular model, so I'm doing a seperate model called files and have model 'A' 'have many' files. But I want my files to be saved in director named by model 'A'. So For example I want something like this: class Show(models.Model): name = models.CharField() showfolder = models.FilePathField() class Episode(models.Model): show = models.ForeignKey(Show) name = models.CharField() files = models.ManyToManyField(mp3) class Mp3(models.Model): file = FileField(upload_to=Episode.show.showfolder) So hopefully that last line expresses what I WANT it to do(get the folder name from Show object associated with the episode). The question is how would I really write that?(besides jumping through hoops in the controller.) Thanks.

• How to define an angular directive inside an angular directive's link function?

  - by user2316667

  I want to create an angular directive inside of a link function, however; the directive created is not able to be compiled. See this JSFiddle: http://jsfiddle.net/v47uvsj5/5/ Uncommenting this directive in the global space works as expected. app.directive('test', function () { return { templateUrl: 'myform', // wraps script tag with id 'myform' restrict: 'E', require: "^mydir", replace: true, scope: { }, link: function (scope, element, attrs, mydirCtrl) { scope.remove = function () { element.remove(); mydirCtrl.remove(); } } } }); But the exact same code inside the link function fails. The reason I want to do this is because I want the user (who is going to be myself) to be able to provide only a script tag's id via an id attribute to my main directive which will in turn create a 'wrapper' directive with a 'remove' method. This way, in the script tag, all one needs to do is implement the 'remove'.

• How to display mysql records as preselected checkboxes?

  - by Jennifer

  I have a table column called post_tags within a table called posts where assigned tags are stored separated by the @ symbol. I also have a table called tags where all tag names are stored. I would like to design my database in a more normalized way but for the purpose I am trying to achieve this is the easiest option. Anyway, I want to display on the screen all the entries from the tags table as checkboxes, so I do: $query = mysql_query("SELECT * FROM tags ORDER BY name"); while ($row = mysql_fetch_assoc($query)) { $tag = $row['name']; echo "<input type='checkbox' name='tags[]' value='$tag' />\n"; } Next I want to have the tags that are assigned to a particular post be preselected. For example, if I have a post with the following in it's post_tags column: party@beaches@dolphins@ I want the "party", "beaches" and "dolphin" checkboxes to be checked by default (while the checkboxes for the other options are unchecked). How can this be done?

• How to rename the original file before sending it to user

  - by Manish Jangir

  Actually I have some download link on my website something like "http://www.example.com/somesong.mp3". Now when user click on this link they get somesong.mp3 but I want to change it before they download. I found many scripts that made it possible but didn't get exact right script. Because I want that when the user clicks on download link the file downloading should be started just after the click with the new file name as I want to use. But in all the scripts which I downloaded, first the php processing starts for a few minute (I think it depends on the file size) and then rename it. Is there a way to direct force the file in header with new file name. Thanks.

• How do I produce an external URL as part of a replace_html call in Ruby on Rails?

  - by vlasits

  Basically, I am attempting to render an external website (the url of which is stored in the database) into a page in my Ruby on Rails app. I have a field in my model 'search' called 'search' that contains web addresses with the form 'www.example.com' or 'example.com'. I am trying to use a link_to_function call with replace_html to replace the 'maincontent' div with an iframe tag using the value of 'search' in the current instance as the src for the tag. My current attempt is the very ugly code below. I'd be grateful for either of the following types of responses: How can I rewrite the concatenation string to work correctly? How can I get the same effect (replacing the current content of the "mainContent" div with an iframe tag using a different method? (I had to modify the code before to remove the < from the iframe) link_to_function h(search.title) do |page| page.replace_html 'mainContent', 'iframe id="embedded" src="http://" + #{search.search} />' end
