  • New to Linux Kernel/Driver development...

    - by CVS-2600Hertz-wordpress-com
    Recently, i began developing a driver of an embedded device running linux. Until now i have only read about linux internals. Having no prior experience in driver devlopment, i am finding it a tad difficult to land my first step. I have downloaded the kernel source-code (v2.6.32). I have read (skimped) Linux Device Drivers (3e) I read a few related posts here on StackOverflow. I understand that linux has a "monolithic" approach. I have built kernel (included existing driver in menuconfig etc.) I know the basics of kconfig and makefile files so that should not be a problem. Can someone describe the structure (i.e. the inter-links) of the various folders in the kernel-source code. In other words given a source-code file, which other files would it refer to for related code (The "#include"-s provide a partial idea) Could someone please help me in getting a better idea? Any help will be greatly appreciated Thank You.

  • MDX equivalent to SQL subqueries with aggregation

    - by James Lampe
    I'm new to MDX and trying to solve the following problem. Investigated calculated members, subselects, scope statements, etc but can't quite get it to do what I want. Let's say I'm trying to come up with the MDX equivalent to the following SQL query: SELECT SUM(netMarketValue) net, SUM(CASE WHEN netMarketValue > 0 THEN netMarketValue ELSE 0 END) assets, SUM(CASE WHEN netMarketValue < 0 THEN netMarketValue ELSE 0 END) liabilities, SUM(ABS(netMarketValue)) gross someEntity1 FROM ( SELECT SUM(marketValue) netMarketValue, someEntity1, someEntity2 FROM <some set of tables> GROUP BY someEntity1, someEntity2) t GROUP BY someEntity1 In other words, I have an account ledger where I hide internal offsetting transactions (within someEntity2), then calculate assets & liabilities after aggregating them by someEntity2. Then I want to see the grand total of those assets & liabilities aggregated by the bigger entity, someEntity1. In my MDX schema I'd presumably have a cube with dimensions for someEntity1 & someEntity2, and marketValue would be my fact table/measure. I suppose i could create another DSV that did what my subquery does (calculating net), and simply create a cube with that as my measure dimension, but I wonder if there is a better way. I'd rather not have 2 cubes (one for these net calculations and another to go to a lower level of granularity for other use cases), since it will be a lot of duplicate info in my database. These will be very large cubes.

  • 2-step user registration with Django

    - by David S
    I'm creating a website with Django and want a fairly common 2-step user registration. What I mean by this is that the user fills in the some basic user information + some application specific information (sort of like a coupon value). Upon submit, an email is sent to ensure email address is valid. This email should contain a link to click on to "finish" the registration. When the link is clicked, the user is marked as validated and they are directed to a new page to complete optional "user profile" type information. So, pretty basic stuff. I have done some research and found django-registration by James Bennett. I do know who James is and have seen him at PyCons and DjanoCons in the past. There is obviously very few people in the world that know Django better than James (so, I know the quality of the code/app is good). But, it almost seems like a bit of over kill. I've read through the docs and was a bit confused (maybe I'm just being a bit dense today). I believe that if I do use django-registration, I will need to have some custom forms, etc. Is there anything else out there I should evaluate? Or are there any good tutorials or videos on using django-registration? I've done a bit of googling, but haven't found anything. But, I suspect that it might be a case of a lot of very common words that don't really find what you are looking for (django user registration tutorial/example). Or is just a case where it would be just about as easy to build your own solution with Django forms, etc? Here is the tech stack I'm using: Python 2.7.2 Django 1.3.1 PostgreSQL 9.1 psycopg2 2.4.1 Twitter Bootstrap 2.0.2

  • WCF Service w/ SharePoint Error: Could not find default endpoint element that references contract...

    - by Brian Clark
    Full error message: Could not find default endpoint element that references contract 'PublicationServices.IPublicationService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element. I have a SharePoint site that I have already opened a project for in Visual Studio 2010. I also created a project that contains a WCF Service Application and added it to the same solution that contains the project for my SharePoint site. I have created a visual web part in my SharePoint project that I am trying to use to consume the WCF Service. I am doing so like this, from within the user control for my web part: PublicationServiceClient proxy = new PublicationServiceClient(); Just having this line alone in OnPreRender, Page_Load, etc. will generate the above error. I've read previous posts about having to have items in the config file of the WCF service also in the config file of the consuming application. I have done this, I copied this section the Web.config file in my WCF service and have placed it in the system.serviceModel tags of my SharePoint project's app.config file: In other words, this is in both of my config files. When I add this web part to the front page of my SharePoint site though, I get the above error every time. I should also note that I have created a console app that I was able to use with no problems to consume data from this very same WCF service. Any help would be appreciated!

  • How do i convert String to Integer/Float in Haskell

    - by Ranhiru
    data GroceryItem = CartItem ItemName Price Quantity | StockItem ItemName Price Quantity makeGroceryItem :: String -> Float -> Int -> GroceryItem makeGroceryItem name price quantity = CartItem name price quantity I want to create a GroceryItem when using a String or [String] createGroceryItem :: [String] -> GroceryItem createGroceryItem (a:b:c) = makeGroceryItem a b c The input will be in the format ["Apple","15.00","5"] which i broke up using words function in haskell. I get this error which i think is because the makeGroceryItem accepts a Float and an Int. But how do i make b and c Float and Int respectively? *Type error in application *** Expression : makeGroceryItem a read b read c *** Term : makeGroceryItem *** Type : String -> Float -> Int -> GroceryItem *** Does not match : a -> b -> c -> d -> e -> f* Thanx a lot in advance :)

  • JList - deselect when clicking an already selected item

    - by Peter
    If a selected index on a JList is clicked, I want it to de-select. In other words, clicking on the indices actually toggles their selection. Didn't look like this was supported, so I tried list.addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent evt) { java.awt.Point point = evt.getPoint(); int index = list.locationToIndex(point); if (list.isSelectedIndex(index)) list.removeSelectionInterval(index, index); } }); The problem here is that this is being invoked after JList has already acted on the mouse event, so it deselects everything. So then I tried removing all of JList's MouseListeners, adding my own, and then adding all of the default listeners back. That didn't work, since JList would reselect the index after I had deselected it. Anyway, what I eventually came up with is MouseListener[] mls = list.getMouseListeners(); for (MouseListener ml : mls) list.removeMouseListener(ml); list.addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent evt) { java.awt.Point point = evt.getPoint(); final int index = list.locationToIndex(point); if (list.isSelectedIndex(index)) SwingUtilities.invokeLater(new Runnable() { public void run() { list.removeSelectionInterval(index, index); } }); } }); for (MouseListener ml : mls) list.addMouseListener(ml); ... and that works. But I don't like it. Is there a better way?

  • Full Text Search MSSQL2008 show wrong display_item for Thai Language

    - by ensecoz
    I am working on MSSQL2008. My task is to investigate the issue that why FTS cannot find the right result for Thai. First, I am having the table which enable the FTS on the column 'ItemName' which is nvarchar. The Catalog is created with the Thai Language. Note that, Thai language is one of the language that doesn't separate the word by space so '????' '???' '????' are written like this in the sentence '???????????' In the table, there are many rows that include the word (????) for examples row#1 (ItemName: '???????????') On the webpage, I try to search for '????' but SQLServer cannot find it. So I try to investigate it by trying the following query in SQLServer select * from sys.dm_fts_parser(N'"???????????"', 1054, 0, 0) To see how the words are broken. The first one is the text to be break. The second parameter is specify that using Thai (WorkBreaker, so on). and here is the result: row#1 (display_item: '????', source_item: '???????????') row#2 (display_item: '????', source_item: '???????????') row#3 (display_item: '??', source_item: '???????????') Notice that the first and second row display the worng display_item '?' in the '????' isn't even Thai characters. '?' in '????' is not Thai charater either. So the question is where is those alien characters come from? I guess this i why I cannot search for '????' because the word breaker is mis-borken and keeping the wrong character in the indexes. Please help!

  • SED - Regular Expression over multiple lines

    - by herrherr
    Hi there, I'm stuck with this for several hours now and cycled through a wealth of different tools to get the job done. Without success. It would be fantastic, if someone could help me out with this. Here is the problem: I have a very large CSV file (400mb+) that is not formatted correctly. Right now it looks something like this: Alan Smithee ist ein Anagramm von „The [...] „Alan Smythee“, und „Adam Smithee“." ,Alan Smithee Die Aussagenlogik ist der Bereich der Logik, der sich mit [...] ihrer Teilaussagen bestimmen. ,Aussagenlogik As you can probably see the words ",Alan Smithee" and ",Aussagenlogik" should actually be on the same line as the foregoing sentence. Then it would look something like this: Alan Smithee ist ein Anagramm von „The Smitheeeee [...] „Alan Smythee“, und „Adam Smithee“.,Alan Smithee Die Aussagenlogik ist der Bereich der Logik, der sich mit [...] ihrer Teilaussagen bestimmen.,Aussagenlogik Please note that the end of the sentence can contain quotes or not. In the end they should be replaced too. Here is what I came up with so far: sed -n '1h;1!H;${;g;s/\."?.*,//g;p;}' out.csv > out1.csv This should actually get the job done of matching the expression over multiple lines. Unfortunately it doesn't :) The expression is looking for the dot at the end of the sentence and the optional quotes plus a newline character that I'm trying to match with .*. Help much appreciated. And it doesn't really matter what tool gets the job done (awk, perl, sed, tr, etc.). Thanks, Chris

  • ASP.NET MVC OutputCache with POST Controller Actions

    - by Maxim Z.
    I'm fairly new to using the OutputCache attribute in ASP.NET MVC. Static Pages I've enabled it on static pages on my site with code such as the following: [OutputCache(Duration = 7200, VaryByParam = "None")] public class HomeController : Controller { public ActionResult Index() { //... If I understand correctly, I made the whole controller cache for 7200 seconds (2 hours). Dynamic Pages However, how does it work with dynamic pages? By dynamic, I mean where the user has to submit a form. As an example, I have a page with an email form. Here's what that code looks like: public class ContactController : Controller { // // GET: /Contact/ public ActionResult Index() { return RedirectToAction("SubmitEmail"); } public ActionResult SubmitEmail() { //In view for CAPTCHA: <%= Html.GenerateCaptcha() %> return View(); } [CaptchaValidator] [AcceptVerbs(HttpVerbs.Post)] public ActionResult SubmitEmail(FormCollection formValues, bool captchaValid) { //Validate form fields, send email if everything's good... if (isError) { return View(); } else { return RedirectToAction("Index", "Home"); } } public void SendEmail(string title, string name, string email, string message) { //Send an email... } } What would happen if I applied OutputCache to the whole controller here? Would the HTTP POST form submission work? Also, my form has a CAPTCHA; would that change anything in the equation? In other words, what's the best way to approach caching with dynamic pages? Thanks in advance.

  • Two DIV layers: resize top DIV based on dynamic height of bottom DIV

    - by user1650713
    I have two DIV layers, one above the other. In the top DIV, there is an image, and in the bottom DIV, there is a block of text. The amount of text in the bottom DIV will change, thus increasing and decreasing the required height. I need to dynamically decrease the height of the image in the top DIV based on how much height is required for the bottom. I have exactly 600px vertical space available. For example: If the bottom DIV requires 200px height, I need for the image to change height to 400px. If the bottom DIV requires 300px height, I need for the image to change height to 300px. I know that I can make the image height 100% of the top DIV, thus allowing it to expand or contract as needed. The issue is that I need for the bottom DIV to be able to expand freely and for the top DIV to react accordingly. In other words, I cannot have either be a fixed height. <div id="topdiv"> <img src="example.png" alt="This image needs a height based on the bottom div" /> </div> <div id="bottomdiv"> This text needs to be able to expand or contract freely </div> Can anyone help?

  • C++ errors not shown in Visual Studio C# project

    - by Diana
    I have in Visual Studio 2008 a .NET 3.5 C# project that uses a dll compiled from a C# project (let's call it dll A). Dll A is using on his turn some C++ libraries. The problem is that when I encounter an error while calling objects from dll A, the application just closes, without showing any error. But I need to know what's the problem, I cannot just guess and go blind all along the project with this... I checked Window's event log, could not find anything. I checked the settings of throwing errors in Visual Studio, in menu Debug - Exceptions, all of them are checked (including C++ exceptions), so, any errors should be thrown. My code looks something like this: tessnet2.Tesseract tessocr = new tessnet2.Tesseract(); tessocr.Init(@"s:\temp\tessdata", "eng", false); tessocr.GetThresholdedImage(bmp, Rectangle.Empty).Save("s:\\temp\\" + Guid.NewGuid().ToString() + ".bmp"); List<tessnet2.Word> words = ocr.DoOCR(bmp, "eng"); //App exits at this line If I put in my code something like int x = Convert.ToInt32("test"); this should throw an error. And it throws, and Visual Studio shows it. Does anyone having any idea why the errors are not being shown? Or where else could be registered? Any help is very appreciated! Thanks!

  • Print raw data to a thermal-printer using .NET

    - by blauesocke
    I'm trying to print out raw ascii data to a thermal printer. I do this by using this code example: http://support.microsoft.com/kb/322091 but my printer prints always only one character and this not until I press the form feed button. If I print something with notepad the printer will do a form feed automatically but without printing any text. The printer is connected via usb over a lpt2usb adapter and Windows 7 uses the "Generic - Generic / Text Only" driver. Anyone knows what is going wrong? How is it possible to print some words and do some form feeds? Are there some control characters I have to send? And if yes: How do I send them? Edit 14.04.2010 21:51 My code (C#) looks like this: PrinterSettings s = new PrinterSettings(); s.PrinterName = "Generic / Text Only"; RawPrinterHelper.SendStringToPrinter(s.PrinterName, "Test"); This code will return a "T" after I pressed the form feed button (This litte black button here: swissmania.ch/images/935-151.jpg - sorry, not enough reputation for two hyperlinks) Edit 15.04.2010 16:56 I'm using now the code form here: c-sharpcorner.com/UploadFile/johnodonell/PrintingDirectlytothePrinter11222005001207AM/PrintingDirectlytothePrinter.aspx I modified it a bit that I can use the following code: byte[] toSend; // 10 = line feed // 13 carriage return/form feed toSend = new byte[1] { 13 }; PrintDirect.WritePrinter(lhPrinter, toSend, toSend.Length, ref pcWritten); Running this code has the same effekt like pressing the form feed button, it works fine! But code like this still does not work: byte[] toSend; // 10 = line feed // 13 carriage return/form feed toSend = new byte[2] { 66, 67 }; PrintDirect.WritePrinter(lhPrinter, toSend, toSend.Length, ref pcWritten); This will print out just a "B" but I expect "BC" and after running any code I have to reconnect the USB cable to make it work agian. Any ideas?

  • Diffie-Hellman in Silverlight

    - by cmaduro
    I am trying to devise a security scheme for encrypting the application level data between a silverlight client, and a php webservice that I created. Since I am dealing with a public website the information I am pulling from the service is public, but the information I'm submitting to the webservice is not public. There is also a back end to the website for administration, so naturally all application data being pushed and pulled from the webservice to the silverlight administration back end must also be encrypted. Silverlight does not support asymmetric encryption, which would work for the public website. Symmetric encryption would only work on the back end because users do not log in to the public website, so no password based keys could be derived. Still symmetric encryption would be great, but I cannot securely save the private key in the silverlight client. Because it would either have to be hardcoded or read from some kind of config file. None of that is considered secure. So... plan B. My final alternative would be then to implement the Diffie-Hellman algorithm, which supports symmetric encryption by means of key agreement. However Diffie-Hellman is vulnerable to man-in-the-middle attacks. In other words, there is no guarantee that either side is sure of each others identity, making it possible for communication to be intercepted and altered without the receiving party knowing about it. It is thus recommended to use a private shared key to encrypt the key agreement handshaking, so that the identity of either party is confirmed. This brings me back to my initial problem that resulted in me needing to use Diffie-Hellman, how can I use a private key in a silverlight client without hardcoding it either in the code or an xml file. I'm all out of love on this one... is there any answer to this?

  • SQL Server 2008 Running trigger after Insert, Update locks original table

    - by Polity
    Hi Folks, I have a serious performance problem. I have a database with (related to this problem), 2 tables. 1 Table contains strings with some global information. The second table contains the string stripped down to each individual word. So the string is like indexed in the second table, word by word. The validity of the data in the second table is of less important then the validity of the data in the first table. Since the first table can grow like towards 1*10^6 records and the second table having an average of like 10 words for 1 string can grow like 1*10^7 records, i use a nolock in order to read the second this leaves me free for inserting new records without locking it (Expect many reads on both tables). I have a script which keeps on adding and updating rows to the first table in a MERGE statement. On average, the data beeing merged are like 20 strings a time and the scripts runs like ones every 5 seconds. On the first table, i have a trigger which is beeing invoked on a Insert or Update, which takes the newly inserted or updated data and calls a stored procedure on it which makes sure the data is indexed in the second table. (This takes some significant time). The problem is that when having the trigger disbaled, Reading the first table happens in a few ms. However, when enabling the trigger and your in bad luck of trying to read the first table while this is beeing updated, Our webserver gives you a timeout after 10 seconds (which is way to long anyways). I can quess from this part that when running the trigger, the first table is kept (partially) in a lock untill the trigger is completed. What do you think, if i'm right, is there a easy way around this? Thanks in advance! Cheers, Koen

  • Output redirection still with colors in PowerShell

    - by stej
    Suppose I run msbuild like this: function Clean-Sln { param($sln) MSBuild.exe $sln /target:Clean } Clean-Sln c:\temp\SO.sln In Posh console the output is in colors. That's pretty handy - you spot colors just by watching the output. And e.g. not important messages are grey. Question I'd like to add ability to redirect it somewhere like this (simplified example): function Clean-Sln { param($sln) MSBuild.exe $sln /target:Clean | Redirect-AccordingToRedirectionVariable } $global:Redirection = 'Console' Clean-Sln c:\temp\SO.sln $global:Redirection = 'TempFile' Clean-Sln c:\temp\Another.sln If I use 'Console', the cmdlet/function Redirect-AccordingToRedirectionVariable should output the msbuild messages with colors the same way as the output was not piped. In other words - it should leave the output as it is. If I use 'TempFile', Redirect-AccordingToRedirectionVariable will store the output in a temp file. Is it even possible? I guess it is not :| Or do you have any advice how to achieve the goal? Possible solution: if ($Redirection -eq 'Console) { MSBuild.exe $sln /target:Clean | Redirect-AccordingToRedirectionVariable } else { MSBuild.exe $sln /target:Clean | Out-File c:\temp.txt } But if you imagine there can be many many msbuild calls, it's not ideal. Don't be shy to tell me any new suggestion how to cope with it ;) Any background info about redirections/coloring/outpu is welcome as well. (The problem is not msbuild specific, the problem touches any application that writes colored output)

  • Synchronous dialogs in Flex?

    - by Yaba
    How can I open a synchronous dialog in Flex? I need to call a function from an External Interface (JavaScript) that will open a simple dialog in the Flex application and returns an value according to the button the user has clicked (OK/Cancel). So it should by a synchronous call to a dialog, i.e. the call waits until the user has closed the dialog like this. //This function is called by JavaScript function onApplicationUnload():Boolean { var result:Boolean; result = showDialogAndWaitForResult(); return result } Does anybody know how I can do this? I could write a loop that waits until the dialog has set a flag and then reads the result to return it, but there must be something that is way more elegant and reusable for waiting of the completion of other asynchronous calls. EDIT: Unfortunately a callback does not work as the JavaScript function that calls onApplicationUnload() itself has to return a value (similar to the onApplicationUnload() function in Flex). This JavaScript function has a fixed signature as it is called by a framework and I cannot change it. Or in other words: The call from JavaScript to Flex must also be synchronous.

  • Need a regular expression to parse a text body

    - by Ali
    Hi guys, I need a regular expression to parse a body of text. Basically assume this that we have text files and each of which contains random text but within the text there would be lines in the following formats - basically they are a format for denoting flight legs. eg: 13FEB2009 BDR7402 1000 UUBB 1020 UUWW FLT This line of text is always on one line The first word is a date in the format DDMMMYYYY Second word could be of any length and hold alphanumeric characters third word is the time in format HHMM - its always numeric fourth word is a location code - its almost always just alphabets but could also be alphanumeric fifth word is the arrival time in format HHMM - its always numeric sixth word is a location code - its almost always just alphabets but could also be alphanumeric Any words which follow on the same line are just definitions A text file may contain among lots of random text information one or more such lines of text. I need a way to be able to extract all this information i.e just these lines within a text file and store them with their integral parts separated as mentioned in an associative array so I have something like this: array('0'=>array('date'=>'', 'time-dept'=>'', 'flightcode'=>'',....)) I'm assuming regular expressions would be in order here. I'm using php for this - would appreciate the help guys :)

  • Positioning SVG Elements

    - by Rob Wilkerson
    In the course of toying with SVG for the first time (using the Raphael library), I've run into a problem positioning dynamic elements on the canvas in such a way that they're completely contained within the canvas. What I'm trying to do is randomly position n words/short phrases. Since the text is variable, its position needs to be variable as well so what I'm doing is: Initially creating the text at point 0,0 with no opacity. Checking the width of the drawn text element using text.getBBox().width. Setting a new x coordinate as Math.random() * (canvas_width - ( text_width/2 ) - pad). Altering the x coordinate of the text to the newly set value (text.attr( 'x', x ) ). Setting the opacity attribute of the text to 1. I'll be the first to admit that my math acumen is limited, but this seems pretty straightforward. Somehow, I still end up with text running off beyond the right edge of my canvas. For simplicity above, I removed the bit that also sets a minimum x value by adding it to the Math.random() result. It is there, though, and I see the same problem on the leading edge of the canvas. My understanding (such as it is), is that the Math.random() bits would generate a number between 0 and 1 which could then be multiplied by some number (in my case, the canvas width - half of the text width - some arbitrary padding) to get the outer bound. I'm dividing the width of the text in half because its position on the grid is set at its center. I hope I've just been staring at this for too long, but is my math that rusty or am I misunderstanding something about the behavior of Math.random(), SVG, text or anything else that's under the hood of this solution?

  • Before data is entered, is there a way to make a grouped table graphic placeholder?

    - by Matt Winters
    I have a grouped table with 3 sections, each section with a title. The 1st and 3rd sections always have only 1 row of information so before any user data is entered, I just put some words like "Enter Data Here..." as placeholder text. This text is edited (replaced) by the user with their own actual data. No problem. The 2nd section however will contain several rows of information entered by user and I'd prefer not to enter placeholder data in row 0, having the user Edit the first row of data then Add subsequent rows. If the numberOfRowsInSection is set to 0, the title for the 3rd section comes close to the title for the 2nd section and it looks ugly. The best that I could come with, and I don't know to do it, is to have a fake graphic placeholder on the striped background (between the 2nd and third titles) that looks like a single row in the 2nd section, put "Enter Data Here..." text in the graphic, and then the first row of actual data entered and all subsequent rows will cover it up. Can anyone tell me how to do this or offer a better suggestion. Thanks.

  • page wide bread crumb bar as at apple.com/store

    - by punkish
    I want to build a (don't know what to call it other than) bread crumb bar at the top of the page, kinda like at http://store.apple.com/us/browse/home/shop_mac/software, y'know, at the top of the page, the horizontal, light grey bar that looks like so [home icon] | Shop Mac | Mac Software Help | Account | Cart Actually, I've got that bar working, with a curved, square left edge, the intermediate chevrons, and the curved, square right edge. So, my bar looks like so [ Home > Foo > Bar > Baz ] I have little graphics fragments that make up the [ and the and the ] and the middle parts. The only problem is, I want the right edge to be at the right edge of my page. So, the above bar should look like so [ Home > Foo > Bar > Baz ] I want to have a variable number of entries in my bread crumb bar... so, I could have "Home, Foo, Bar, Baz" or I could have "Home, Foo" or "Home, Foo, Bar, Baz, Qux" and so on. In other words, I want the right edge of my bar to be dynamically long enough to extend to the edge of my web page. Suggestions?

  • How does GMail implement Comet?

    - by Morgan Cheng
    With the help of HttpWatch, I tried to figure out how GMail implement Comet. I Login in GMail with two account, one in IE and the other in Firefox. Chatting in GTalk in GMail with some magic words like "WASSUP". Then, I logoff both GMail accounts, filter any http content without "WASSUP" string. The result shows which HTTP request is the streaming channel. (Note: I have to logoff. Otherwise, never-ending HTTP would not show content in HttpWatch.) The result is interesting. The URL for stream channel is like: https://mail/channel/bind?VER=8&at=xn3j33vcvk39lkfq..... There is no surprise that GMail do Comet in IE with IFRAME. The Http content starts with " Originally, I guessed that GMail do Comet in Firefox with multipart XmlHttpRequest. To my surprise, the response header doesn't have "multipart/x-mixed-replace" header. The response headers are as below: HTTP/1.1 200 OK Content-Type: text/plain; charset=utf-8 Cache-Control: no-cache, no-store, max-age=0, must-revalidate Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Date: Sat, 20 Mar 2010 01:52:39 GMT X-Frame-Options: ALLOWALL Transfer-Encoding: chunked X-Content-Type-Options: nosniff Server: GSE X-XSS-Protection: 0 Unfortunately, the HttpWatch doesn't tell whether a HTTP request is from XmlHttpRequest or not. The content is not HTML but JSON. It looks like a response for XHR, but that would not work for Comet without multipart/x-mixed-replace, right? Is there any way else to figure out how GMail implement Comet? Thanks.

  • validation properties by attribute

    - by netmajor
    I create class with two property - name,link(below). I use simple property validation by Required and StringLength attribute. I bind this class object to WPF ListBox(with textBoxs). But when I have textbox empty or write words longer than 8 sign nothing happens :/ What should I do to fires ErrorMessage? Or how to implement validation in other way ? I also try use : if (value is int) { throw new ArgumentException("Wpisales stringa!!"); } But it only fires in debug mode :/ My class with implementation of attribute validation: public class RssInfo : INotifyPropertyChanged { public RssInfo() { } public RssInfo(string _nazwa, string _link) { nazwa = _nazwa; link = _link; } private string nazwa; [Required(ErrorMessage = "To pole jest obowiazkowe nAZWA")] public string Nazwa { get { return nazwa; } set { if (value != nazwa) { nazwa = value; onPropertyChanged("Nazwa"); } if (value is int) { throw new ArgumentException("Wpisales stringa!!"); } } } private string link; [Required(ErrorMessage="To pole jest obowiazkowe link")] [StringLength(8, ErrorMessage = "Link cannot be longer than 8 characters")] public string Link { get { return link; } set { if (value != link) { link = value; onPropertyChanged("Link"); } } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion private void onPropertyChanged(string propertyName) { if (this.PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } }
