  • help me understand the method Validator.TryValidateObject()

    - by Benny
    this is the method definition: public static bool TryValidateObject( Object instance, ValidationContext validationContext, ICollection<ValidationResult> validationResults, bool validateAllProperties ) what i am confused is the validateAllProperties parameter, I understand when it is true-validate all properties. What about when it is false, not validate all properties, but which property will be validated?

  • Help passing _POST Form Data PHP

    - by Mikey1980
    I apologize in advance, I am a PHP noob! I have form with some hidden fields. I need the values to POST to "submit_rma.php" so that they're not missing from the db--I need $qty, $estmate_id and $rma_type. The rest of the fields are just displaying data for the user and are readonly. Currently I only get value from the qty text field. Is there any easier way to pass these values? URL is out of the question due to security issues. <form method="post" action="submit_rma.php";> <table> <tr> <td> Quantity </td> <td> <input type="text" name="qty" value="<?php echo $qty ?>" size="1"/><br/> </td> </tr> <tr> <td> Part # </td> <td> <input type="text" name="" value="<?php echo $model ?>" size="8" READONLY/><br/> </td> </tr> <tr> <td> Description </td> <td> <input type="text" name="" value="<?php echo $name_EN ?>" size="50" READONLY/><br/> </td> </tr> <tr> <td> Paid Date </td> <td> <input type="text" name="" value="<?php echo $sold_date ?>" size="6" READONLY/><br/> </td> </tr> <tr> <td> Amount Each </td> <td> <input type="text" name="" value="<?php echo $dealer_price ?>" size="8" READONLY/> </td> </tr> </table> <input type="hidden" name="estmate_id" value="<?php echo $estmate_id ?>"> <input type="hidden" name="rma_type" value="Short Shipped"> <input type="submit" name="submit";"> </form>

  • HTML IFrame Help

    - by Josh K
    Hey Few Questions 1.Is it legal to have an IFrame on a website which inside has an external website? 2.In an IFrame is it possible to only show a section of the src that isnt the top left of the site (for instance if there was a chart in the middle of a website, could u have just the chart in your Iframe, or atleast start it centred there) 3.Any way to stop my IFrame from auto redirecting me to the external site for 3: ie <iframe src="http://fifa.com"></iframe> Just sends me to fifa instead of actually showing that site in a frame.

  • Little Regular Expression (against HTML) help

    - by Marcos Placona
    Hi, I have the following HTML <p>Some text <a title="link" href="http://link.com/" target="_blank">my link</a> more text <a title="link" href="http://link.com/" target="_blank">more link</a>.</p> <p>Another paragraph.</p> <p>[code:cf]</p> <p>&lt;cfset ArrFruits = ["Orange", "Apple", "Peach", "Blueberry", </p> <p>"Blackberry", "Strawberry", "Grape", "Mango", </p> <p>"Clementine", "Cherry", "Plum", "Guava", </p> <p>"Cranberry"]&gt;</p> <p>[/code]</p> <p>Another line</p> <p><img src="http://image.jpg" alt="Array" /> </p> <p>More text</p> <p>[code:cf]</p> <p>&lt;table border="1"&gt;</p> <p> &lt;cfoutput&gt;</p> <p> &lt;cfloop array="#GroupsOf(ArrFruits, 5)#" index="arrFruitsIX"&gt;</p> <p>  &lt;tr&gt;</p> <p> &lt;cfloop array="#arrFruitsIX#" index="arrFruit"&gt;</p> <p>     &lt;td&gt;#arrFruit#&lt;/td&gt;</p> <p> &lt;/cfloop&gt;</p> <p>  &lt;/tr&gt;</p> <p> &lt;/cfloop&gt;</p> <p> &lt;/cfoutput&gt;</p> <p>&lt;/table&gt;</p> <p>[/code]</p> <p>With an output that looks like:</p> <p><img src="another_image.jpg" alt="" width="342" height="85" /></p> What I'm trying to do, is write a regular expression that will remove all the or , and whenever it finds a , it will replace it with a line-break. So far, my pattern looks like this: /\<p\>(.*?)(<\/p>)/g And I'm replacing the matches with: $1\n It all looks good, but it's also replacing the contents inside the [code][/code] tags, which in this case should not replace the tags at all, so as a result, i would lkike to get rid of the tags, when the content isn't inside the [code] tags. I can't ever get negation right, I know it will be something along the lines of \<p\>^\[code*\](.*?)(<\/p>) But obviously this doesn't work :-) Could anyone please lend me a hand with this regex? BTW, I know I shouldn't be using regular expressions to parse HTML at all. I'm fully aware of that, but still, for this specific case, I'd like to use regex. Thanks in advance

  • Need help regarding lwuit

    - by rajiv
    Hi, I have project, already developed using canvas and lib used is LCDUI. It's for nokia keyboard supported devices. Now I want to incorporate same application for touch devices. I have used touch methods like pointerpressed, etc. For normal functionality that worked pretty well. But it creates problem in commands. My application is in fullscreen mode. Commands I have created using user defined menu list. Probles is that I can not directly identify that which command has been clicked. Setting coordinates for every command is not thr feasible solution for me. I come across the new lib LWUIT, but i found out that it supports only forms(Can't we use on canvas?). and integrating LCDUI and LWUIT is also not possible(please give suggestion that can we use both in same application?). Is it possible to create form under canvas itself? Any other lib support available? thank you.

  • help me understand cuda

    - by scatman
    i am having some troubles understanding threads in NVIDIA gpu architecture with cuda. please could anybody clarify these info: an 8800 gpu has 16 SMs with 8 SPs each. so we have 128 SPs. i was viewing stanford's video presentation and it was saying that every SP is capable of running 96 threads cuncurrently. does this mean that it (SP) can run 96/32=3 warps concurrently? moreover, since every SP can run 96 threads and we have 8 SPs in every SM. does this mean that every SM can run 96*8=768 threads concurrently?? but if every SM can run a single Block at a time, and the maximum number of threads in a block is 512, so what is the purpose of running 768 threads concurrently and have a max of 512 threads? a more general question is:how are blocks,threads,and warps distributed to SMs and SPs? i read that every SM gets a single block to execute at a time and threads in a block is divided into warps (32 threads), and SPs execute warps.

  • Help with an SQL query on a single (comments) table (screenshot included)

    - by citrus
    Please see screenshot Goal: id like to have comments nested 1 level deep The comments would be arranged so that rating of the parent is in descending order the rating of the children comments is irrelevant The left hand side of the screenshot shows the output that Id like. The RHS shows the table data. All of the comments are held in 1 table. Im a beginner with SQL queries, the best I can do is: SELECT * FROM [Comments] WHERE ([ArticleId] = @ArticleId) ORDER BY [ThreadId] DESC, [DateMade] This somewhat does the job, but it obviously neglects the rating. So the above statement would show output where Bobs Comment and all of the children comments are before Amy's and her childrens comments. How can I run this query correctly?

  • Need help understanding .net ThreadPool

    - by Meredith
    I am trying to understand what ThreadPool does, I have this .NET example: class Program { static void Main() { int c = 2; // Use AutoResetEvent for thread management AutoResetEvent[] arr = new AutoResetEvent[50]; for (int i = 0; i < arr.Length; ++i) { arr[i] = new AutoResetEvent(false); } // Set the number of minimum threads ThreadPool.SetMinThreads(c, 4); // Enqueue 50 work items that run the code in this delegate function for (int i = 0; i < arr.Length; i++) { ThreadPool.QueueUserWorkItem(delegate(object o) { Thread.Sleep(100); arr[(int)o].Set(); // Signals completion }, i); } // Wait for all tasks to complete WaitHandle.WaitAll(arr); } } Does this run 50 "tasks", in groups of 2 (int c) until they all finish? Or I am not understanding what it really does.

  • Need help with threads in a client/server

    - by nunos
    For college, I am developing a local relay chat. I have to program a chat server and client that will only work on sending messages on different terminal windows on the same computer with threads and fifos. The fifos part I am having no trouble, the threads part is the one that is giving me some headaches. The server has one thread for receiving commands from a fifo (used by all clients) and another thread for each client that is connected. For each client that is connected I need to know a certain information. Firstly, I was using global variables, which worked as longs as there was only one client connected, which is much of a chat, to chat alone. So, ideally I would have some data like: -nickname -name -email -etc... per client that is connected. However, I don't know how to do that. I could create a client_data[MAX_NUMBER_OF_THREADS] where client_data was a struct with everything I needed to have access to, but this would require to, in every communication between server and client to ask for the id of the client in the array client_data and that does not seem very pratical I could also instantiate a client_data immediately after creating the thread but it would only be available in that block, and that is not very pratical either. As you can see I am in need of a little guidance here. Any comment, piece of code or link to any relevant information is greatly appreciated. Thanks.

  • Help dealing with data dependency between two registration forms

    - by franko75
    I have a tricky issue here with a registration of both a user and his/her pet. Both the user and the pet are treated as separate entities and both require separate registration forms. However, the user's pet has to be linked to the user via a foreign key in the database. The process is basically that when a new user joins the site, firstly they register their pet, then they register themselves. The reason for this order is to check their pet's eligibility for the site (there are some criteria to be met) first, instead of getting the user to sign up only to then find out their pet is ineligible. It is this ordering of the form submissions which is causing me a bit of a headache, as follows... The site is being developed with an MVC framework, and the User registration process is managed via a method in a User_form controller, while the pet registration process is managed via a method in the Pet_form controller. The pet registration form happens first, and the pet data can be saved without the owner_id at this stage, with the user id possibly being added (e.g by retrieving pet's id from session) following user registration. However, doing it this way could potentially result in redundant data, where pet records would be created in the database, but if the user doesn't actually register themselves too, then the pets will be ownerless records in the DB. Other option is to serialize the new pet's data at the pet registration stage, don't save it to the DB until the user fills out their registration form. Once the user is created, i can pass serialised data AND the owner_id to a method in the Pet Model which can update the DB. However, I also need to set the newly created $pet to $this-pet which I then access for a sequence of other related forms. Should I just set the session variable in the model method? Then in the Pet controller constructor, do a check for pet stored in session, if yes, assign to $this-pet... If this makes any sense to anybody and you have some advice, i'd be grateful to hear it!

  • Regular expression help parsing SQLIO output

    - by jaspernygaard
    Hi I've been working on a regular expression to parse the output of a series of SQLIO runs. I've gotten pretty far, but not quite there yet. I'm seeking a 100% regex solution and no pre-manipulation of the input. Could anyone assist with a little guidance with the following regular expression: .*v(?<SQLIOVersion>\d\.\d).*\n.*\n(?<threads>\d*)\s.*for\s(?<Seconds>\d+).*\n.*using\s(?<clustersize>[0-9]*)KB.*\n.*\n.*size:\s(?<currentfilesize>\d+).*\n.*\n.*\n.*\n.*\s(?<IOs>\d*\.\d*).*\n.*\s(?<MBs>\d*\.\d*).*\n.*\n.*\s(?<MinLatency_ms>\d+).*\n.*\s(?<AvgLatency_ms>\d+).*\n.*\s(?<MaxLatency_ms>\d+).*\n.*\n.*\n\%\:..(?<ms>\d*\s+)* Here's a snippet of the output - note the headers, which change during the SQLIO batch run: File

  • Need Help with Page Life Cycle(I think it is screwing me up)

    - by chobo2
    Hi I have dragged a empty asp.net table onto my webform. I generate all the rows in the code behind those. Now my table gets filled up and has dropdown lists. When the user hits save I go through all the rows and update the values from the dropdownlist in the db. This works all great. However if 2 columns have each have "Present" then those 2 columns should be not be shown anymore and 2 new columns get put in its place with other dropdown lists. This all works. However you have to refresh the entire page to for the 2 columns that should go away to go away. So what I tried to do is at the end of the button click event. Clear the whole table and then regenerate it. However when I do this then my values are not saved to the database anymore for whatever reason. if (IsPostBack == false) { // check if dummy variables exist in db- If true just generate tables with values in db. If not generate them. } else { // grab the values from the database // generate tables with the values } btn click event { go through all rows in table(foreach loop) update each column in the database with cells in each row. while in foreach loop. //done } So this is how it goes and it works expect(all correct values are saved) the table is just not updated to the user. Does not work if (IsPostBack == false) { // same code as above } // if postback is true do nothing. By the time it gets to the click event it says there is zero rows in the table so nothing happens. btn click event { // same code } Fails also. if (IsPostBack == false) { // same code as above } else { // same code as above but moved into its own method. gernerateTable(); } btn click event { // update all rows // once done clear the Tables rows // call generateTable() } This last one does nothing as for some reason it does not update anything. I don't understand why. So what am I doing wrong with this life cycle something in my process is wrong. The code works just not when I want the table to be updated right away.

  • Help regarding no sql databases like hadoop, hbase etc

    - by user560370
    I am new to the distributed NoSQL databases like Hadoop, Cassandra, etc. I have few questions for which I seek an expert advice: Can you list problems/challenges one will generally face when making a shift from the present conventional database like MySQL to these large cluster-based databases? What are the difficulties, if any, when one needs to adapt to a newer version of these open source projects? Can you list out the things which are generally stored/kept in memcached for fast rendering of the page? How can I understand the source code of open-source projects so that I can build on it and maybe give back to the community? Above questions may sound to be idiotic and basic but please it's a request for the experts to answer the above questions in detailed and to best of their abilities.

  • jQuery Validation help

    If you look here: http://creathive.net you will see I have an application form down at the bottom of the page and I have added some jQuery validation to make a user fills it out correctly. However what I would like to do is instead of showing all those labels next to the input boxes (which breaks the layout) is just keep it simple and only change the colours of the input fields. How do I do this? Thanks.
