    - by giri
    when i click the New Trade button in the form it opens jquery ui dialog. but, i have link button in the gridview when i click the link button it should open jquery ui dialog, it opens jquery ui dialog before clicking the new trade button. but, after clicking the new trade button, if i click link button in the gridview it invoke "ViewTradeDialog(id)" function, the dialog doesn't open, it shows error message "$vwdia.html(data).dialog is not a function". my code follows: @using (Html.BeginForm("NewTrade", "Trade", FormMethod.Post, new { id = "searchForm" })) { <div id="searchbtn"> <input id="btn_newtrade" type="submit" value="New Trade" /> </div> } jquery code <script type="text/javascript"> $(function () { var $loading = $('<img src="../../loading.gif" alt="loading">'); var $dialog = $('<div></div>').append($loading); $('#searchForm').submit(function (e) { var url = this.action; $.ajax({ autoOpen: false, url: url, success: function (data) { $dialog.html(data).dialog({ zIndex:1, width: 1400, height: 600, resizable: false, title: 'New Trade Details', modal: true, buttons: { "close": function () { $dialog.dialog('close'); }, "Add Trade": function () { $dialog.dialog('close'); $.ajax({ type: 'POST', url: url }); } } }); } }); return false; }); }); function ViewTradeDialog(id) { alert(id); var $vwdia = $('<div></div>'); var url = '/Trade/ViewTrades?tradeid=' + id; $.ajax({ url: url, success: function (data) { $vwdia.html(data).dialog({ width: 600, height: 600, resizable: false, title: 'View Trade Details', modal: false, buttons: { "close": function () { $vwdia.dialog('close'); } } }); } }); return false; }

  • What data should I use to create an autofill "destination" field like Facebook or the Trip Advisor s

    - by sbar
    In order to create a “destination” auto filter input field on our website, I need a data source that provides a hierarchical data set of Region, Country, County/State, City and Town (plus an area like the Peak District National Park if at all possible) I know sites like Trip Advisor and Facebook seem to have very robust datasets for this. When you type, it brings up a match list with the hierarchy displayed (e.g. if you type Boston you get 6 results as there are multiply places called Boston – the hierarchy allows you to pick the correct option) There are many data sources out there but they either lack hierarchy or do not seem to be easily updatable or complete. I had expected this to be an easy task given the amount of site that have a destination or location autofill field. However, i cannot find a datasource or method that works. any help would be much appreciated. Tks,

  • How do you write an idiomatic Scala Quicksort function?

    - by Don Mackenzie
    I recently answered a question with an attempt at writing a quicksort function in scala, I'd seen something like the code below written somewhere. def qsort(l: List[Int]): List[Int] = { l match { case Nil => Nil case pivot::tail => qsort(tail.filter(_ < pivot)) ::: pivot :: qsort(tail.filter(_ >= pivot)) } } My answer received some constructive criticism pointing out that List was a poor choice of collection for quicksort and secondly that the above wasn't tail recursive. I tried to re-write the above in a tail recursive manner but didn't have much luck. Is it possible to write a tail recursive quicksort? or, if not, how can it be done in a functional style? Also what can be done to maximise the efficiency of the implementation? Thanks in advance.

  • How do I apply a string function to an array?

    - by ggg
    I was fortunate enough to receive this code (flips Lastname, Firstname) from an earlier post. $name = "Lastname, Firstname"; $names = explode(", ", $name); $name = $names[1] . " " . $names[0]; How do I apply the function to each value in an array that is in the form: $ginfo ->$(LastName, FirstName). I tried the code below, but it doesn't work. $name1 =($ginfo->White); $name1 = explode(", ", $name1); $FLw = $name1[1] . " " . $name1[0]; foreach ($name1 as ($ginfo->White)) {return($FLw);}

  • In Python, how to use a C++ function which returns an allocated array of structs via a ** parameter?

    - by Jon-Eric
    I'd like to use some existing C++ code, NvTriStrip, in a Python tool. SWIG easily handles the functions with simple parameters, but the main function, GenerateStrips, is much more complicated. What do I need to put in the SWIG interface file to indicate that primGroups is really an output parameter and that it must be cleaned up with delete[]? /////////////////////////////////////////////////////////////////////////// // GenerateStrips() // // in_indices: input index list, the indices you would use to render // in_numIndices: number of entries in in_indices // primGroups: array of optimized/stripified PrimitiveGroups // numGroups: number of groups returned // // Be sure to call delete[] on the returned primGroups to avoid leaking mem // bool GenerateStrips( const unsigned short* in_indices, const unsigned int in_numIndices, PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false ); FYI, here is the PrimitiveGroup declaration: enum PrimType { PT_LIST, PT_STRIP, PT_FAN }; struct PrimitiveGroup { PrimType type; unsigned int numIndices; unsigned short* indices; PrimitiveGroup() : type(PT_STRIP), numIndices(0), indices(NULL) {} ~PrimitiveGroup() { if(indices) delete[] indices; indices = NULL; } };

  • Implicit declaration when using a function before it is defined in C, why can't the compiler figure this out?

    - by rolls
    As the title says, I know what causes this error but I want to know why the compiler gives it in this circumstance. Eg : main.c void test(){ test1(); } void test1(){ ... } Would give an implicit declaration warning as the compiler would reach the call to test1() before it has read its declaration, I can see the obvious problems with this (not knowing return type etc), but why can't the compiler do a simple pass to get all function declarations, then compile the code removing these errors? It just seems so simple to do and I don't believe I've seen similar warnings in other languages. Does anyone know if there is a specific purpose for this warning in this situation that I am overlooking?

  • define a closure as method from class

    - by user272839
    Hi, i'm trying to play with php5.3 and closure. I see here (Listing 7. Closure inside an object : http://www.ibm.com/developerworks/opensource/library/os-php-5.3new2/index.html) that it's possible to use $this in the callback function, but it's not. So I try to give $this as use variable : $self = $this; $foo = function() use($self) { //do something with $self } So to use the same example : class Dog { private $_name; protected $_color; public function __construct($name, $color) { $this->_name = $name; $this->_color = $color; } public function greet($greeting) { $self = $this; return function() use ($greeting, $self) { echo "$greeting, I am a {$self->_color} dog named {$self->_name}."; }; } } $dog = new Dog("Rover","red"); $dog->greet("Hello"); Output: Hello, I am a red dog named Rover. First of all this example does not print the string but return the function, but that's not my problem. Secondly I can't access to private or protected, because the callback function is a global function and not in the context from the Dog object. Tha't my problem. It's the same as : function greet($greeting, $object) { echo "$greeting, I am a {$self->_color} dog named {$self->_name}."; } And I want : public function greet($greeting) { echo "$greeting, I am a {$self->_color} dog named {$self->_name}."; } Which is from Dog and not global. I hope that I am clear ...

  • Passing variables to functions in Python

    - by brno792
    Im writing test scripts in python for selenium web testing. How do I pass parameters through a python function to call in a later function? I first have a login test function. Then I have a new user registration function. Im trying to pass the Username and Password I use in the registration function to the testLogin function that I call inside the testRegister function. This is my python code: userName = "admin" password = "admin" #pass username and password variables to this function def testLogin(userName,password): browser = webdriver.Firefox() browser.get("http://url/login") element = browser.find_element_by_name("userName") element.send_keys(userName) element = browser.find_element_by_name("userPassword") element.send_keys(password) element.send_keys(Keys.RETURN) browser.close() # test registration def testRegister(): browser = webdriver.Firefox() browser.get("http://url/register") #new username variable newUserName = "test" element = browser.find_element_by_name("regUser") element.send_keys(newUserName) #new password variable newUserPassword = "test" element = browser.find_element_by_name("regPassword") element.send_keys(newUserPassword) # #now test if user is registered, I want to call testLogin with the test user name and pw. testLogin(newUserName,newUserPassword) browser.close()

  • In C, as free() knows an array size, why isn't there a function that gets the array size? [closed]

    - by user354959
    Possible Duplicate: If free() knows the length of my array, why can’t I ask for it in my own code? Searching around (including here at stackoverflow), I got that malloc() allocates an array and also creates a header to control the array info. In this header, there's also the array size. free() use such information to know how to deallocate that array. So, if the array size info is "there" (somewhere in the memory), why there isn't a function that returns an array size, looking for this at the array header? Or am I missing something?

  • Applying a function with multiple inputs using Map? (Haskell)

    - by Schroedinger
    G'day guys, Trying currently to finish up a bit of homework I'm working on, and having an issue where I'm trying to apply map across a function that accepts multiple inputs. so in the case I'm using processList f (x:xs) = map accelerateList f xs x xs processList is given a floating value (f) and a List that it sorts into another List Accelerate List takes a floating value (f) a List and a List Object through which it returns another List Object I know my Accelerate List code is correct, but I cannot for the life of me get the syntax for this code working: processList :: Float -> [Object] -> [Object] accelerate f [] = [] accelerate f [x] = [(accelerateForce f x x)] accelerate f (x:xs) = map accelerateList f xs x xs Any ideas? I've been scratching my head for about 3 hours now. I know it's something really simple.

  • Efficient implementation of threads in the given scenario

    - by shadeMe
    I've got a winforms application that is set up in the following manner: 2 buttons, a textbox, a collection K, function X and another function, Y. Function X parses a large database and enumerates some of its data in the global collection. Button 1 calls function X. Function Y walks through the above collection and prints out the data in the textbox. Button 2 calls function Y. I'd like to call function X through a worker thread in such a way that: The form remains responsive to user input. This comes intrinsically from the use of a separate thread. There is never more than a single instance of function X running at any point in time. K can be accessed by both functions at all times. What would be the most efficient implementation of the above environment ?

  • Does a static object within a function introduce a potential race condition?

    - by Jeremy Friesner
    I'm curious about the following code: class MyClass { public: MyClass() : _myArray(new int[1024]) {} ~MyClass() {delete [] _myArray;} private: int * _myArray; }; // This function may be called by different threads in an unsynchronized manner void MyFunction() { static const MyClass _myClassObject; [...] } Is there a possible race condition in the above code? Specifically, is the compiler likely to generate code equivalent to the following, "behind the scenes"? void MyFunction() { static bool _myClassObjectInitialized = false; if (_myClassObjectInitialized == false) { _myClassObjectInitialized = true; _myClassObject.MyClass(); // call constructor to set up object } [...] } ... in which case, if two threads were to call MyFunction() nearly-simultaneously, then _myArray might get allocated twice, causing a memory leak? Or is this handled correctly somehow?

  • Can I create many tables according to the same entity?

    - by jacob
    What I want to do is that I want to make the many tables dinamically which are the same entity structures. And then I want to refer to the dinamically created tables according to the table name. What I understood from hibernate reference is that I can only create only one table and it should be matched exactly with entity. So I can't find any solution to my problem. If you know any relevent open source related to my problem or any tip or web site, let me know. Thanks allways

  • Can I create a DC without a DNS Server?

    - by onik
    So as the title says, I need to promote a standalone Win2008R2 server to a Domain Controller, and I don't a DNS Server (I think), as there will be no clients connected to the domain, it will be only used for Remote Desktop Services. Yes, I know, it's considered bad practice to install other roles on the DC, but in this case, it's necessary. Do I need to install the DNS Server, and if I do, how to make it as transparent as possible? EDIT: Seems that I need to install the DNS Server, so I can I configure it not to mess up my entire domain? For example: The server I need to promote is rdc.mydomain.com, and it has an A entry to it's IP in the current DNS, while other servers under mydomain.com are running Linux and don't need to know anything about this Windows box. The domain uses a third-party DNS and all edits and updates need to be done via a separate web page, our servers don't have write/update access.

  • I need to know how to create a custom webform template in ASP.NET that allows me to pick a master pa

    - by Pete
    Using Visual Studio 2008, I need to create a custom web form that when picked acts like the web content form, by providing a dialog that lets you pick a master page. I have looked through the webform.zip template and thought I had a clue, but trying different combinations has baffled me as it either doesn't appear or doesn't work. Also when you set the project type to Web and sub project type to CSharp it doesn't appear, so I don't know if this part of the cause, because I would of hoped that the SupportsMasterPage element would of caused this dialog to appear, if it is a web item, but no luck. Frown Any ideas? p.s. I have used my googling resources to the maximum so unsure what to do.

  • Can we create a class from a xml file ?

    Hello, Is it possible to create a class dynamically by reading an xml file ( in java preferably) ? if yes, please provide pointers on how to do it. In the process of development, we have come up with a class that has 5 attributes, all these attributes correspond to an entry in the xml file, now if the user adds/modifies the xml entry the object corresponding to it must change automatically, one approach would be generate the source code, before compile time.Is there any other way ? Is there any common pattern to model such changes in the system ? Thanks,

  • Can I create a virtual network interface to connect to a real network device?

    - by michelemarcon
    I have a networked windows pc with 2 network interfaces. The first connects to a lan with ip address 10.1.. The second connects to another lan with ip address 10.2.. Maybe it's a dumb question, however is it possible to virtualize the second network interface, so that the pc can connect to the 2 lans? If necessary, I may switch to linux or paravirtualization. CLARIFICATION: I want to send DHCP broadcast packets on the second lan, but not on the first lan. I want to do it with one single physical network interface. At the moment, I'm not using any virtualization software.

  • How would I create a technology standards document for my company?

    - by Rob O
    I'm a Director of Product Engineering for my company. My CEO has asked me to create a technology standards document, explaining things like the technology we use, our policy on adapting to new technology, and design standards like percent of code covered by unit tests. I've never had to do something like this, and I've spent a significant amount of time searching the web for examples, but I haven't found any at all. The closest I've found are documents describing technical specifications for an individual product. However, I'm trying to define this for the entire company. Can someone provide examples of how this document could be formatted/organized, and what the typical content would be? Thanks!

  • How to Create VBA Add-In with Shared Codes for All Excels?

    I'm writing VBA codes for multiple Excel spreadsheets, which will be shared with others from time to time. At some point I find there are lots of duplications in my works. So I want to find a way to share codes in a sort of Excel add-in, like the .xla file. But when I tried to save the Excel file containing shared codes as .xla file, I got some problems: The file cannot be edit anymore after I save it in the default add-in folder If I move the .xls file to a folder other than the add-in folder, and open it directly - I cannot use its classes - which creates problems for sharing the codes Any ideas to create add-ins in a flexible and powerful way please? Thanks a lot for the help
