  • Are there any code libraries that validate/convert blog comments to XHTML strict?

    - by Matthew James Taylor
    I am working on a website in PHP where people can make comments similar to a blog, and I only want particular tags to be allowed. Are there any pre-built libraries that process comments and produce valid XHTML Strict code? I would need to do this in JavaScript so I can generate a live preview like Stack Overflow, plus in PHP before saving it to a MySQL database. The allowed HTML tags will be: strong, em, blockquote, and links (rel=nofollow not required) One way would be to allow people to directly enter the HTML into the comment field but I would prefer to use a simple mark up something like this (can be different - this is an example): *strong* _em_ [blockquote] http://www.link.com I want line breaks to be converted to <br />. Are there any code libraries that do the above?

  • maths in Javascript.

    - by Jared
    Can someone please help me out with a javascript/jquery solution for this arithmetic problem... I need to subtract one number from the other. The problem is that the numbers have dollar signs (because its money). So it seems that jquery is treating them as strings instead of numbers. I have created two variables - toalAssets and totalLiabilites. I would like to subtract the latter from the former and place the result into another variable called netWorth Perhaps i need to use 'parseFloat'? But I'm not sure how - his is all a little over my head!

  • Delphi overwrite existing file on save dialog

    - by AfterImage
    Hello everyone, I am using the TSaveDialog component to save a file from a button click. However, I am having trouble with saving on an existing file name. Generally, when you want to save over an existing file in Windows, a message box pops up asking you if you really want to overwrite the file. This is not the case with the TSaveDialog component and it will go ahead and write over the file without asking. I was hoping there was a TSaveDialog function or event that I could use but I have not seen anything that looks like it handles this. So it could be that I simplely haven't found the correct method to use. If there is an event, I could use if FileExists(saveDialog.FileName) then //and so forth but the events TSaveDialog has are OnCanClose, OnClose, OnFolderChange, OnIncludeItem, OnSelectionChange, OnShow, OnTypeChange... My question is, how do I pop up a message box to ask the user if they want to overwrite the existing file using the TSaveDialog component. Thanks.

  • Sending Outlook 2007 Meeting Request with HTML Body

    - by Rick Make
    I know that Outlook.ApointmentItem.Body only supports plain and rich text formats. But my requirement is to send the Appointment with a Html body. Currently I am saving the ApointmentItem as an ics file and attaching it to the e-mail. This works but the outcome that I am looking for is that it is received as a meeting request. I.e. I receive this e-mail I can see the body and have the option to respond to the meeting request. I tried forwarding the AppointmentItem as a vCal but that does not work either. I am I headed in the right direction? Thanks

  • Looking for a good example usage of get_or _create in Django views and raising a Form error

    - by Rik Wade
    I am looking for a good example of how to achieve the following: I would like to use get_or_create to check whether an object already exists in my database. If it does not, then it will be created. If it does exist, then I will not create the new object, but need to raise a form error to inform the user that they need to enter different data (for example, a different username). The view contains: p, created = Person.objects.get_or_create( email = registration_form.cleaned_data['email'], defaults = { 'creationDate': datetime.datetime.now(), 'dateOfBirth': datetime.date(1970,1,1) }) So 'p' will contain the existing Person if it exists, or the new Person if not. I would like to act on the boolean value in 'created' in order to skip over saving the Person and re-display the registration_form and raise an appropriate form validation error. The alternative I'm considering is doing a check in a custom Form validation method to see whether a Person exists with the data in the provided 'email' field, and just raising a validation error.

  • iPhone App link to iStore for commission

    - by Simon
    Is it possible to link from an iPhone application to the iStore so a user can (a) play a sample of music and then navigate to that track in order to buy it? In a bit more detail: the application lists a number of tracks for a particular artist (a recommendation by the app based on user criteria). The user scrolls down the list and finds a track that they are interested in. They play the 30 second sample (as you would in the iStore) and then, if they like it, they press on a link that takes them to the iStore where they can purchase the track. If they buy the track, then the application gets 5% of the money paid for the track. I have looked through the web and found a number of suggestions but nothing seems to fit the specification above. I would be very grateful if anyone is able to tell me whether this is possible and some clues as to how it would be done. Thanks, Simon...

  • UIAlertController handle dismiss upon click outside (IPad)

    - by Tomer Peled
    Previous to iOS8 we used the UIActionSheet for showing alert and now we need to use the UIAlertController. When we used the UIActionSheet we could easily handle situations where the user clicked outside the pop up (which means he want to cancel the operation) by comparing the clickedButtonAtIndex to the cancelButtonIndex - if the user indeed pressed outside the popup we got the cancel button index in this function. How can we handle these situations with the new UIAlertController? I tried to use the "completion" block but it doesn't have any context. Is there an easy way to handle this? (other than "saving" the actions states in some general variable).

  • Problem comparing keys in Appengine/Python

    - by ana
    I'm trying to create a relationship between "tables" with Appengine/Python. Imagine I have a "table" for items, and a table for colors. I save the color of an item by saving the color key as an atribute of the item. That's working well, but this particular piece of code is not working: <select id="colorKey" name="colorKey"> {% for color in colors %} <option value="{{ color.key }}"{% if color.key = item.colorKey %} selected="selected"{% endif %}> {{ color.name }} - {{ item.colorKey }} - {{ color.key }} </option> {% endfor %} </select> Since the {{ item.colorKey }} and {{ color.key }} variables are actually the same chain of characters, I only can think in a problem with the types. {{ item.colorKey }} is a string for sure. But maybe {{ color.key }} is not?

  • Predict Stock Market Values

    - by mrlinx
    I'm building a web semantic project that gathers the maximum ammount of historic data about a certain company and tries to predict its future market stock values. For data I have the historic stock values (not normalized), news (0 to 1 polarity) and subjective content (also a 0 to 1 polarity). What is the best AI system to train and use for this kind of objective? Is a simple NN with back-propagation training the best I can hope for? update: Everyone is concerned about the quality of this system. Although I'm pretty sure the system is as good as a random prediction (or even worse), this is a school project around artificial intelligence and web semantics. Therefore I'm only concerned in picking the best kind of train method for the data I have (NN, RBF, SVM, Bayes, neuro-fuzzy, etc). Its not about making money.

  • iPad Orientation Paradigm

    - by JustinXXVII
    I'm not a super awesome designer so this new paradigm has me a little cranky. The iPad is not supposed to have a standard orientation, and should/shall display screen contents at whichever orientation the user decides. This has me sort of stumped. I can keep my UI designed the way I want it in landscape mode, but switching to portrait, I just can't determine the best way to present app content. I know it's all speculation at this point, but what are the chances we can override the autoRotateToOrientation to only include the orientation of our choice? Apple ignored the HIG on a lot of issues for iPhone, including splash screens, saving state, etc. I know we can't really argue with Apple, but doesn't it sound slightly ridiculous to reject an app because it won't rotate to portrait? I've come a long way porting some code to iPad and it works great in landscape mode. I guess only time will tell. What do you all think?

  • Detecting your application's install path in Java?

    - by Danny King
    Hi, I have made a small application in Java and I would like to make a windows installer for it using the Nullsoft Scriptable Install System (http://nsis.sourceforge.net/Main_Page). The application I made needs to save user preferences somewhere and it currently saves it in the user's home directory (e.g. c:\Users\danny or /home/users/danny). However if the windows installer installs the application to e.g. c:\Program Files\whatever\ I should probably save the preferences file there too, right? How would I detect that directory path in Java? What would be a good cross-platform approach to this without losing the benefits of a windows uninstaller for windows users e.g. start menu icons, installer option, etc? Should I just continue saving my preferences in the user's home path and clutter it up? Thanks very much,

  • Reducing differences in xibs

    - by tewha
    I've been noticing superfluous changes in my xib files with Interface Builder 3.2.1. Here are a few of them: - <reference key="NSNextResponder"/> + <nil key="NSNextResponder"/> - <reference key="NSSuperview"/> - <array class="NSMutableArray" key="IBDocument.EditedObjectIDs"> - <integer value="6"/> - </array> + <array class="NSMutableArray" key="IBDocument.EditedObjectIDs"/> Can anyone tell me what these are, and are there any tricks for avoiding them? I'd prefer my checkins to only describe changes I intentionally made. Update: I wasn't clear in the original question, but these differences were caused by opening the file in Interface Builder and saving it without making a change.

  • Using Twitter OAuth for automatic status update

    - by ebae
    I want my website to automatically post status updates to a particular twitter account using OAuth in PHP. I test this using a URL www.mysite.com/update_status but it asks me for "user name" and "password", which is fine when I am testing it. But my website will not be able to insert this user name and password before posting the status update. So the question is how can a website which is in the server, automatically post a status update to an account without user filling out the user name and password. Is there any way to bypass this? I tried saving oAuth tokens, but it's not working. Thank you for your answer in advance!

  • Which offer to pick?

    - by Shawn
    OK. This is kinda silly, but I'd really like to hear what you guys say. Here is the thing: I used to be an php developer and started looking for jobs 3 weeks ago and now I got 2 offers at hand. If I took the first one what I do would be 100% in PHP - simply dev works on a ecommerce project. If I go with the second one, the projects would be in python which I didn't have too much experiences on and is kinda exited about the new stuff I'm going to learn. But wait, the first offer gives more money(1k plus) and that's why I'm still hesitating and troubling you guys.) If you were me, which one would you pick? I know there could be other factors to be considered like 'which position is closer to your home so you could take good care of your dog', well let's forget about those things for now.

  • OpenLayers Projections.

    - by Jenny
    I can succesfully do: point.transform(new OpenLayers.Projection("EPSG:900913"), new OpenLayers.Projection("EPSG:4326")); To a point that is in the google format (in meters), but when I want to do the reverse: point.transform(new OpenLayers.Projection("EPSG:4326"), new OpenLayers.Projection("EPSG:900913")); to a point that is in 4326 (regular lat/lon format), I am having some issues. Any negative value seems to become NaN (not a number) when I do the transformation. Is there something about the transformation in reverse that I don't understand? Edit: Even worse, when I have no negative values, the coordinates seem off. I am getting the coordinates by drawing a square on the screen, then saving those coordinates to a database and loading them later. I can draw a square near the tip of africa (positive coordinates), and then when it loads it's near the top of africa, in the atlantic ocean. I'm definitely doing something wrong....

  • How do I include 2 tables in LocalStorage?

    - by Noor
    I've got a table that you can edit, and I've got a simple code saving that list when you're done with editing it. (the tables have the contenteditable on) The problem I've stumbled upon is that if I double click on enter, the table gets divided into two separate tables with the same ID. This causes the code I'm using to set the localStorage to only store one of the tables (I assume the first).. I've thought of different solutions and I wonder if someone could point out the pro's and con's (if the solutions even works that is). Make a loop that checks the page after tables and stores them into an array of localStorage-items.. I'd have to dynamically create a localStorage item for each table. Take the whole div that the tables are in, and store that in the localStorage, when a user revisits the page, the page checks after the items in storage and displays the whole divs. Any suggestions you have that can beat this :).. (but no cache, it has to be with the localStorage!) Thanks

  • Using SQLLite transactions I/O Error

    - by james.ingham
    I currently have a client / server setup where the client sends data to the server and then the server saves the data to a SQLite database file. To do this I am using transactions which works fine in windows 7 when I run around 30 clients (each client sending data back between 5 - 30 seconds). When using the same software in Windows XP, I can get/set data multiple times with no problems until I run around 20 clients I start to get Windows Delayed wrote failed errors: This fires an exception on the server: I'm assuming this is either something to do with XP or a hardware issue on the machine i'm running XP. Does anyone have any advice to avoid this? Or if I should just catch the exception and retry saving the data? Thanks

  • view to select specific period or latest when null

    - by edosoft
    Hi I have a product table which simplifies to this: create table product(id int primary key identity, productid int, year int, quarter int, price money) and some sample data: insert into product select 11, 2010, 1, 1.11 insert into product select 11, 2010, 2, 2.11 insert into product select 11, 2010, 3, 3.11 insert into product select 12, 2010, 1, 1.12 insert into product select 12, 2010, 2, 2.12 insert into product select 13, 2010, 1, 1.13 Prices are can be changed each quarter, but not all products get a new price each quarter. Now I could duplicate the data each quarter, keeping the price the same, but I'd rather use a view. How can I create a view that can be used to return prices for (for example) quarter 2? I've written this to return the current (=latest) price: CREATE VIEW vwCurrentPrices AS SELECT * FROM ( SELECT *, ROW_NUMBER() OVER (PARTITION BY productid ORDER BY year DESC, quarter DESC) AS Ranking FROM product ) p WHERE p.Ranking = 1 I'd like to create a view so I can use queries like select * from vwProduct where quarter = 2

  • ODBC datasource for DB2 on 64 bit Windows 2008

    - by Rob Vermeulen
    First of all, sorry for this non-programming question. I just finished development of some code that communicates with DB2 and want to test/deploy it on a Windows 2008 machine. I'm a bit concerned about not being able to find a working ODBC datasource (DSN/client) driver for DB2 on Windows 2008 (x64). I have a 32-bit driver for XP but that one (obviously) won't install on 2008-64. The IBM web site comes up with 1844 results when searching for "ODBC Windows 2008", but none of them are relevant. The web site's also a pain to use, btw. While googling around I found some solutions by 3rd party vendors but they all want money :) And the DB2 client and ODBC driver from IBM have always been free-of-charge. Does anyone have a solution?

  • Must have JavaScript pro developer tools, libs, utilities and workshop configuration.

    - by WooYek
    This is a followup question to the Pro JavaScript programmer interview questions (with answers). What is considered professional and industrial standard for a professional browser side Java Script developer when it comes to his workshop configuration, and maybe from-concept-to-shipment process? What are the most popular IDE's, utilities and probably libraries, not limited to the free ones. These that can help cut development time (eg. IDE), help with achieve better quality (eg. unit testing tools), reliability and maintainability. I'm looking for a baseline to which I could compare potential candidates based on their ability to keep their tools sharp and workshop efficient (pro's should invest time&money in good tools, right?).

  • C# parsing txt files IF name format is desired format

    - by jakesankey
    OK, I have txt files that I am parsing and saving into a sql db. The names are formatted like R306025COMP_272A4075_20090929_080159.txt However, there are a select few (out of thousands of files) with names that are formatted differently (particularly files that were generated as tests), example R306025COMP_SU2_TestBottom_20090915_101441.txt The reason this causes a problem for me is that I am using Split('_')[1,2,etc] to extract the R number, the 272A4075 portion, and the 20090929 (date) portion. When the application comes across the oddly named files, it fails because it is trying to parse 'TestBottom' as a date and inserts 'SU2' instead of the 272 number. Basically I want the app to recognize that if the file's name is not formatted like my first example, skip it. Any advice?
