  • JSON.stringify() supported by IE 8?

    - by user246114
    I need to use: JSON.stringify() which should be supported by chrome, safari, and FF (I think). I think IE8 also has support for the JSON object. I think IE7 and 6 do not, so I'm doing this: <!--[if lt IE 8]> <script src="http://www.json.org/json2.js"></script> <![endif]--> so, I think this will import the external javascript only if IE6 & 7. I looked at the url where the script is hosted, they are including only if the IE version is less than 9: http://code.google.com/p/html5shiv/ <!--[if lt IE 9]> <script src="http://www.json.org/json2.js"></script> <![endif]--> so should I be including this for IE 8 too? Thanks --------------- Pointed script source to json parser js ---------------

  • wxPython formatting questions

    - by Kevin
    I have an app I was working on to learn more about wxPython( I have been primarily been a scripter ). I forgot about it now I am opening it back up. It's a screen scraper, and I have it working almost the way I want it, going to build a regex parser to strip out the links in every scrape that I don't need. The questions I have are this. In it current state, if I check more than one site, it goes out and scrapes, and returns it in separate windows, the for:each section in the Clicked function. I want to put them in a frame, in the window, altogether. I also want to know if I can take the list they are read into and send it to a checklist, so someone could check off separate items, I want to build a save function and keep certain ones. In regards to a save function, I want to keep saved checks, are there calls to the widgets to save their states? I know it's a lot, but thanks for the help.

  • Detailstext in TableView from Coredata Iphone

    - by user554867
    Hey, that is my first question here at stackoverflow. Let me try to be specific as I can. The project is as follows: I am trying to parse an xml file in an iphone app, which works already. I am saving the parsed data into the CoreData of the Iphone. So far so good: I have two elements of the xml file which I want to show in the tableview as the text and the detailtext. Now the strange behaviour occurs: If I take the data of the Core Data and trying to visualize them in the tableview, then both elements are displayed in seperate cells and not as detailtext of the element. If I am just taking a constant string for the detailtext, then it works, but if I am trying to take for every cell a specific element from the Core Data then it is shown seperately in the tableview. I googled a lot, reading here and there. I dont know which code I should show because I dont have a clue where exactly the mistake could be. Maybe someone can answer that immediately because it is a stupid mistake somewhere, which is common. Thanks for your help.

  • Listing known CSS classes using Javascript

    - by Fred Oliveira
    I'm trying to find a good way to collect the names of classes defined in the stylesheets included with a given document. I know about document.StyleSheetList but it doesn't seem like it'd be easy to parse. What I'm looking for is something like, for a stylesheet document such as: .my_class { background: #fff000; } .second_class { color: #000000; } I could extract an array like ["my_class", "second_class"]. This obviously assumes the favorable scenario of a fully loaded dom and stylesheets. I've been looking everywhere for a good way to do something like this and so far, have made little progress. Does anyone have any idea about how to pull this off? Thanks!

  • Best Solution For Authentication in Ruby on Rails

    - by Dan Wolchonok
    I'm looking for a pre-built solution I can use in my RoR application. I'm ideally looking for something similar to the ASP.NET Forms authentication that provides email validation, sign-up controls, and allows users to reset their passwords. Oh yeah, and easily allows me to pull the user that is currently logged into the application. I've started to look into the already written pieces, but I've found it to be really confusing. I've looked at LoginGenerator, RestfulAuthentication, SaltedLoginGenerator, but there doesn't seem to be one place that has great tutorials or provide a comparison of them. If there's a site I just haven't discovered yet, or if there is a de-facto standard that most people use, I'd appreciate the helping hand.

  • Backbone.js "model" query

    - by Novice coder
    I'm a learning coder trying to understand this code from a sample MVC framework. The below code is from a "model" file. I've done research on Backbone.js, but I'm still confused as to exactly how this code pull information from the app's database. For example, how are base_url, Model.prototype, and Collection.prototype being used to retrieve information from the backend? Any help would be greatly appreciated. exports.definition = { config : { "defaults": { "title": "-", "description": "-" }, "adapter": { "type": "rest", "collection_name": "schools", "base_url" : "/schools/", } }, extendModel: function(Model) { _.extend(Model.prototype, { // Extend, override or implement Backbone.Model urlRoot: '/school/', name:'school', parse: function(response, options) { response.id = response._id; return response; }, }); return Model; }, extendCollection: function(Collection) { _.extend(Collection.prototype, { // Extend, override or implement Backbone.Collection urlRoot: '/schools/', name: 'schools', }); return Collection; } }

  • ASP.NET MVC 2 Model object validation

    - by Jimmy
    Hey guys, I'm trying to validate a model object outside of the context of ModelState within a controller, I currently have a parser that creates model objects from an excel file and I want to be able to report how many entries were added to the database and how many failed, is there a way to validate a model object on its data annotations outside of model binding? I'm looking for something similar to the rails model method of model.valid? or a way for me to implement that myself. My current solution is just manually checking if a few key fields are present but this duplicates requirements between my model class and its metadata, there has to be a better way to hook into the model validation checking that is done by mvc 2. Thanks

  • Layout: how to make image to change its width and height proportionally?

    - by Exterminator13
    I have such layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_centerVertical="true" android:layout_toLeftOf="@+id/my_image" android:ellipsize="end" android:singleLine="true" android:text="Some text" android:textAppearance="?android:attr/textAppearanceMedium" /> <ImageView android:id="@+id/my_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@+id/title" android:layout_alignBottom="@+id/title" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:adjustViewBounds="true" android:src="@drawable/my_bitmap_image" /> This layout does almost what I need: it makes image view height the same as text view. The image graphic contents stretched also keeping aspect ratio. But, the width of the image view does not change! As a result, I have a wide gap between text and the image view! As a temporal solution, I override View#onLayout. The question: how to change image width in xml layout? UPDATE: This is a final layout I need (text + a few images). Look at the first image: its width should be exactly the same as scaled image in it with no paddings and margins:

  • iPhone: Get value in multi-dimentional array

    - by Nic Hubbard
    I have an array that is many levels deep and I am wondering what is the best way to get one of the child element values that is deep in my array. I assume I need to use a recursive method, but what is the best way to do this? Or is there a faster way to do this? The array comes from an XML Parser that I am using which builds everything into an array like this (using NSLog to show the structure): { children = ( { children = ( { children = ( { children = ( ); data = 12; element = AssetID; } ); data = ""; element = "ns1:GetUserIdByUsernameResponse"; } ); data = ""; element = "SOAP-ENV:Body"; } ); data = ""; element = "SOAP-ENV:Envelope"; } What I would like to get at is the AssetID data, which in this case is 12.

  • Get name and value from the input tag

    - by DroidIn.net
    Before you say "oh no, not again" here I'm stating my case. I'm parsing part of HTML output and the only thing I'm interested in is name and value attributes of each <input/ tag. HTML is actually HTML fragment, may not be well-formed. I don't have DOM or HTML parser and I don't try to parse nested elements anyway. The problem is that I don't know the order or number of attributes so it could be <input name="foo" value="boo"/> or <input type="hidden" name=foo> or <input id=blah value='boo' src="image.png" name="foo" type="img"/>. Is there a single regular expression that would get me values of name and value attribute in predictable order? I wouldn't have asked the question if I could assume that name attribute always precedes value but unfortunately this is not the case

  • using regular expression / Remove special characters with linq to sql

    - by Prasad
    How can i use regular expressions with linq to sql in the asp.net mvc(C#) application? The columns in my MSSQL table (Products) has some special characters like (, - % ',.....). While searching for a product i need to search without that special chareters. For ex.: I have a product say (ABC-Camp's / One), when i search for "abccamp", it should pull the product. I am trying the query like: from p in _context.pu_Products where p.User_Id == userId && p.Is_Deleted == false && p.Product_Name.ToLower().Contains(text.ToLower()) select new Product { ProductId = p.Product_Id, ProductName = p.Product_Name.Replace("’", "").Replace("\"", ""), RetailPrice = p.Retail_Price ?? 0M, LotSize = p.Lot_Size > 0 ? p.Lot_Size ?? 1 : 1, QuantityInHand = p.Quantity_In_Hand ?? 0 } But i need to search without any special characters...

  • XSL(like) declarative language as MVC view over strongtyped model?

    - by Martin Kool
    As a huge XSL fan, I am very happy to use xsl as the view in our proprietary MVC framework on ASP.NET. Objects in the model are serialized under the hood using .NET's xml serializer, and we use quite atomic xsl templates to declare how each object or property should transform. For example: <xsl:template match="/Article"> <html> <body> <div class="article"> <xsl:apply-templates /> </div> </body> </html> </xsl:template> <xsl:template match="Article/Title"> <h1> <xsl:apply-templates /> </h1> </xsl:template> <xsl:template match="@*|text()"> <xsl:copy /> </xsl:template> This mechanism allows us to quickly override default matching templates, like having a template matching on the last item in a list, or the selected one, etc. Also, xsl extension objects in .NET allow us just the bit of extra grip that we need. Common shared templates can be split up and included. However Even though I can ignore the verbosity downside of xsl (because Visual Studio schema intellisense + snippets really is slick, praise to the VS-team), the downside of not having intellisense over strongtyped objects in the model is really something that's bugging me. I've seen ASP.NET MVC + user controls in action and really starting to love it, but I wonder; Is there a way of getting some sort of intellisense over XML that we're iterating over, or do you know of a language that offers the freedom and declarativeness of XSL but has the strongtype/intellisense benefits of say webforms/usercontrols/asp.net.mvc-view? (I probably know the answer: "no", and I'll find myself using Phil Haack's utterly cool mvc shizzle soon...)

  • The meaning of tracking in git

    - by user273158
    In an article that has been cited in StackOverflow a few times (e.g. 1) , the author discusses the asymmetry between git push and git pull, and mentions the following: Update: Thanks to David Ongaro, who points out below that since git 1.7.4.2, the recommended value for the push.default option is upstream rather than tracking, although tracking can still be used as a deprecated synonym. The commit message that describes that change is nice, since it suggests that there is an effort underway to deprecate the term “track” in the context of setting this association with the upstream branch in a remote repository. (The totally different meanings of “track” in git branch --track and “remote-tracking branches” has long irritated me when trying to introduce git to people.) What is exactly the difference that he is referring to with: The notion of "tracking" in git branch --track The notion of "tracking" in remote-tracking branches in the last sentence?

  • Need help getting buttons to work...

    - by Mike Droid
    I am trying to get my first button to update a display number in my view when clicked. This view will have several buttons and "outputs" displayed. After reading examples and Q's here, I finally put something together that runs, but my first button is still not working; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.ship_layout); mSwitcher = (TextSwitcher) findViewById(R.id.eng_val); } private TextSwitcher mSwitcher; // Will be connected with the buttons via XML void onClick(View v){ switch (v.getId()) { case R.id.engplus: engcounter++; updateCounter(); break; case R.id.engneg: engcounter--; updateCounter(); break; } } private void updateCounter() { mSwitcher.setText(String.valueOf(engcounter)); } The .xml for this button is; <TextSwitcher android:id="@+id/eng_val" android:visibility="visible" android:paddingTop="9px" android:paddingLeft="50px" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/build" android:layout_toRightOf="@+id/engeq" android:textColor="#DD00ff00" android:textSize="24sp"/> This is within a Relative Layout that appears otherwise OK. When I had set the view to have a TextView with the number set as a string , the number displayed, but I could not figure out how to update the text with a numerical field. That may be my real problem. I have gone through many examples generally referenced from the dev. site (UI, Common Tasks, various samples), and I am still not seeing the connection here... Again, this is simply a try at getting variables to respond to buttons and update on the view. So, a few Q's for anyone that can help; 1) Is there any easier way of doing this (ie. send numerical value to View) ? 2) Why isn't my TextSwitcher displaying the number? 3) Should I be using a TextSwitcher here? 4) Any examples of this you can point me to?

  • reStructuredText for SQL?

    - by Chris
    I am trying to use DocUtils and reStructuredText to comment SQL code. I can get this to work when I include the markup inside multi-line comments. I then use --Some text:: to introduce each block of code. I cannot get internal hyperlinks to work. I would like to write -- .. Step1_: but the parser ignores this because of the leading comment. Using a multi-line style also fails. Is there a way to get this to work? Here's an example: /* ========== this query ========== :Author: Me Outline ========== - Create table 1 - Create table 2 - Output the result */ -- _Step1: build the table:: create table table1 -- _Step2: use Step1_ to build table 2:: create table table2

  • Transform LINQ Dataset into a Matrix for export

    - by Mad Halfling
    Hi folks, I've got a data table with columns in which include Item, Category and Value (and others, but those are the only relevant ones for this problem) that I access via LINQ in a C# ASP.Net MVC app. I want to transform these into a matrix and output that as a CSV file to pull into Excel as matrix with the items down the side, the categories across the top and the values in the row cells. However, I don't know how many, or what, categories there will be in this table, nor will there always be a record for each item/category combination. I've written this by looping round, getting my "master category" list, then looking again for each item, filling in either blank or Value, depending on whether the item/category record exists, but as there are currently 27000 records in the table, this isn't as fast as I'd like. Is there a slicker and faster way I can do this, maybe via LINQ (firing into a quicker SQL statement so the DB server can do the leg-work), or will any method essentially come back to what I am doing? Thx MH

  • Automator / AppleScript to process incoming emails in Mac Mail

    - by mark
    Hello all, I'm designing an app that allows users to email me crash reports if my app ever crashes. I'd like to leave Mac Mail running on a computer and when an email comes through, an automator script / AppleScript runs to process the contents of the body of the email. I've got the entire parsing/processing done in a python script, except I have to manually copy the contents of the email into a file and then run my parser on that file. What's the best way to set this up so I can the contents of the email be pushed into my parsing script? Many thanks!

  • Which reporting tool would you recommend?

    - by grady
    Hi, I have some reporting functionality in my app and I want to improve it a bit. Its only SQL in a XML file which is read by some parser. There can be some params for that SQL and when its parsed and the params are injected, it is executed against my DB (SQL Server). I want to improve that a bit so that the results look better and are more flexible. This are the most important points I need to have: subtotals layout that can change dynamically according to settings in DB (like logo, slogan) possibility to use the same report template for several customers (same fields, but different logos,colors, slogans etc.) should run from an ASP.NET application It should be as dynamic as possible. I know of Crystal Reports and the Microsoft Reporting Tool. Are there any others that might be of interest and are my above points possible at all? Thanks for some ideas and hints :-)...

  • Change clickable TextView's color on focus and click?

    - by Daniel Jonsson
    I have a clickable TextView that I want to give some colors to. But I don't know how. Here are the relevant code snippets from my two files that I'm working with: TextView title = new TextView(this); title.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); title.setTextColor(R.color.textcolor); title.setText(titleLine); title.setTypeface(null, Typeface.BOLD); title.setClickable(true); title.setId(idLine); title.setFocusable(true); title.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { /* Irrelevant code */ } }); And this is my textcolor.xml file: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:color="#000000"/> <!-- pressed --> <item android:state_focused="true" android:color="#000000"/> <!-- focused --> <item android:color="#000000"/> <!-- default --> </selector> When I use the textcolor-file by typing title.setTextColor(R.color.textcolor);, the textcolor just becomes grey, regardless if I press it or so. Which is strange since I have written "#000000" in all color fields. But if I remove the setTextColor code, gets the textView a light grey color, and when I press it, it becomes black. But that aren't the colors that I want. So, can anyone help me with this problem? Just to clarify: I want to be able to specify the colors for the text when it's normal, pressed and focused.

  • Git: How do I rewind the Master branch on the remote origin

    - by user277260
    I made 5 commits to Master branch when bug hunting on a private project and pushed them to the remote origin (my own private vps). Then I saw that commits 4 and 5 were going to cause trouble elsewhere and I need to undo them, so I checked out commit 3 again, made a new branch "Dev" from that point, and did a few more commits fixing the issue properly. Then I did git reset --hard HEAD~2 on Master to pull it back to the point that I branched Dev. Then I did git merge to fast forward Master back to the end of the Dev branch. So now I have a local repository, with Dev and Master both pointing to the same, up to date version of the project with the latest bug fix. Problem is, when I try to push the project now to the origin, it fails and gives me an error message: ! [rejected] master - master (non-fast forward) error: failed to push some refs to 'myserver...myproject.git' What have I done wrong, and how do I fix it? Thanks

  • ListView exception for Images + Text

My main class is very small slightly modified from the tutorial: public class Stuffs extends ListActivity { static final String[] COUNTRIES = new String[] {"A", "B","C"}; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.title, COUNTRIES)); } } and my list_item.xml file is this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation = "horizontal"> <ImageView android:id = "@+id/icon" android:src="@drawable/icon" /> <TextView android:id = "@+id/title" android:padding="10dp" android:textSize="16sp" > </TextView> </LinearLayout> I have also created a "drawable" directory in my res directory and copied a "icon.png" into it. But any time I try to run this the application hangs up unexpected in my android emulator. Am I missing something?

  • Add two hexBinarys with XPATH 1.0

    - by fielding
    Hi, my xml document looks somewhat like that (Values are both xsl:hexBinary): <Offsets> <Offset> <Name>ErrorOffset</Name> <Value>DD</Value> </Offset> <Offset> <Name>OtherOffset</Name> <Value>FF</Value> </Offset> </Offsets> <Value> <Name>Error1</Name> <Code>01</Code> </Value> <Value> <Name>Error2</Name> <Code>02</Code> <Offset>ErrorOffset</Offset> </Value> now i want to transform this to a new xml file: <Value> <Name>Error1</Name> <Code>01</Code> </Value> <Value> <Name>Error2</Name> <Code>DF</Code> </Value> All that should happen is adding <Offset> to the basic <Value>. But plain + returns NaN and sum() expects only one parameter. XSLT and XPATH are quite nice, but it goes on my nerves that easy operations like adding two hex values just dont work as easy as it should.

  • how to start writing a very simple programming language

    - by Rex Homming
    Recently, I was going around looking for ideas on what I can build using C this summer and I came across this post: http://stackoverflow.com/questions/1257376/interesting-project-to-learn-c Implement a programming language. This doesn't have to be terribly hard - I did the language that must not be named - but it will force you to learn a lot of the important parts of C. If you don't want to write a lexer and/or parser yourself, you can use lex/flex and yacc/bison, but if you plan on that you might want to start with a somewhat smaller project. I was kinda intrigued about the implementing a programming language answer and I'm wondering how do I go about starting this? I've gone through the whole K&R book and I've done some of the exercises as well. I also have a bit of experience in C++ and Java if that matters. Any tips? Thanks!

  • How to use LINQ To Entities for filtering when many methods are not supported?

    - by Kinderchocolate
    Hi, I have a table in SQL database: ID Data Value 1 1 0.1 1 2 0.4 2 10 0.3 2 11 0.2 3 10 0.5 3 11 0.6 For each unique value in Data, I want to filter out the row with the largest ID. For example: In the table above, I want to filter out the third and fourth row because the fifth and sixth rows have the same Data values but their IDs (3) are larger (2 in the third and fourth row). I tried this in Linq to Entities: IQueryable<DerivedRate> test = ObjectContext.DerivedRates.OrderBy(d => d.Data).ThenBy(d => d.ID).SkipWhile((d, index) => (index == size - 1) || (d.ID != ObjectContext.DerivedRates.ElementAt(index + 1).ID)); Basically, I am sorting the list and removing the duplicates by checking if the next element has an identical ID. However, this doesn't work because SkipWhile(index) and ElementAt(index) aren't supported in Linq to Entities. I don't want to pull the entire gigantic table into an array before sorting it. Is there a way?
