  • Dynamically generating high performance functions in clojure

    - by mikera
    I'm trying to use Clojure to dynamically generate functions that can be applied to large volumes of data - i.e. a requirement is that the functions be compiled to bytecode in order to execute fast, but their specification is not known until run time. e.g. suppose I specify functions with a simple DSL like: (def my-spec [:add [:multiply 2 :param0] 3]) I would like to create a function compile-spec such that: (compile-spec my-spec) Would return a compiled function of one parameter x that returns 2x+3. What is the best way to do this in Clojure?

  • Self Modifying Code

    - by Betamoo
    I am recently thinking about writing self-modifying programs, I think it may be powerful and fun... So I am currently looking for a language that allow modifying program own code easily.. I read about C# and the ability to compile -and execute- code in runtime, but that is too hurting.. I am also thinking about assembly... it is easier there to change running code but it is not very powerful... Can you suggest me a powerful language -or a feature- that support modifying code in runtime..? Hint: That what I mean by modifying code in runtime Start: a=10,b=20,c=0 label1: c=a+b .... label1= c=a*b goto label1 Thanks

  • How can I get my div id to reload via ajax and jquery

    - by Matt Nathanson
    I'm creating a CMS using jQuery and AJAX. When I click, my "Add Campaign" buttom, it creates a unique client ID in the DB and on a hard reload, the new client shows up in its container. I am trying to use ajax to reload the container on the fly and I'm not having the exact luck i am hoping for. I can get it to reload, but it's like it's pulling in descriptions of each of the clients as well! function AddNewClient() { dataToLoad = 'clientID=' + clientID + '&addClient=yes'; $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, target: ('#clientssidebar'), async: false, success: function(html){ $('#clientssidebar').html(html); }, error: function() { alert('An error occured!'); } }); };

  • Problems with Database Search Code (asp.net vb)

    - by Phil
    Here is a sample of my database search code: Dim sql As String = "Select * From Table Where " Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim andor As Boolean = AndOr1.SelectedValue 'selection can be AND or OR (0 / 1) 'Code for when the user selects AND If NameSearch.Text.ToString IsNot String.Empty And andor = 0 Then sql += "Surname LIKE '%" & name & "%' AND " End If If EmailSearch.Text.ToString IsNot String.Empty And andor = 0 Then sql += "Email LIKE '%" & email & "%' AND " End If If CitySearchBox.Text.ToString IsNot String.Empty And andor = 0 Then sql += "City LIKE '%" & city & "%' AND " End If 'Code for when the user selects OR If NameSearch.Text.ToString IsNot String.Empty And andor = 1 Then sql += "(Surname LIKE '%" & name & "%' OR " End If If EmailSearch.Text.ToString IsNot String.Empty And andor = 1 Then sql += "Email LIKE '%" & email & "%') OR " End If If CitySearchBox.Text.ToString IsNot String.Empty And andor = 1 Then sql += "(City LIKE '%" & city & "%' OR " End If sql = CleanString(sql) End Sub When the user selects AND (as andor.selectedvalue(0)) then the sql is produced fine like this; Select * From Table Where Surname LIKE '%test%' AND Email LIKE '%test%' AND City LIKE '%test%' But if the user selects OR (as andor.selectedvalue(1)), nothing is outputted except; Select * From Table Where Im sure the controls have values so are not string.empty and when the user selects OR the correct value 1 is being assigned to andor.

  • SQL Server pivots? some way to set column names to values within a row

    - by ccsimpson3
    I am building a system of multiple trackers that are going to use a lot of the same columns so there is a table for the trackers, the tracker columns, then a cross reference for which columns go with which tracker, when a user inserts a tracker row the different column values are stored in multiple rows that share the same record id and store both the value and the name of the particular column. I need to find a way to dynamically change the column name of the value to be the column name that is stored in the same row. i.e. id | value | name ------------------ 23 | red | color 23 | fast | speed needs to look like this. id | color | speed ------------------ 23 | red | fast Any help is greatly appreciated, thank you.

  • GDI: Dynamical Multiple Graphics in a page?

    - by SirLenz0rlot
    Hi all, I'm quite new to drawing shapes, graphics, bitmaps etc. I googled for a few days,but still havent got a real clue what to do, so please help me: I want to draw a floorplan with certain objects(represented as circles) moving on it. When I click on a object, it needs to show something. So far, I ve been able to draw some circles on a graphic and been able to move the dots by clearing the graphic every time. Ofcourse, this isnt a real solution, since I cant keep track of the different objects on the floorplan (which i need for my clickevent and movings). I hope I explained my problem ok here. This is the (stripped version of the) sourcecode that gets called every second: (dev (of type Device) is the object i want to draw) Graphics gfx = FloorplanTabPage.CreateGraphics(); gfx.Clear(Color.White); foreach (Device dev in _deviceList) { Pen myPen = new Pen(Color.Black) { Width = 10 }; dev.InRoom != null) { myPen.Color = Color.DarkOrchid; int x = dev.InRoom.XPos + (dev.InRoom.Width / 2) - 5; int y = (dev.InRoom.YPos + (dev.InRoom.Height / 2) - 5; if (dev.ToRoom != null) { x = (x + (dev.ToRoom.XPos + (dev.ToRoom.Width / 2)) / 2; y = (y + (dev.ToRoom.YPos + (dev.ToRoom.Height / 2)) / 2; } gfx.DrawEllipse(myPen, x, y, 10, 10); gfx.DrawString(dev.Name, new Font("Arial", 10), Brushes.Purple, x, y - 15); } }

  • SWF (using XML) only working locally, not on home server or web hosting server

    - by Andy
    Hi, I use a main SWF file, which has some animations. It uses xml from a .php file which specifies several items, e.g. images and other SWFs to be used in the main SWF. Locally everything works perfectly, but when invoking it via my home server, or hosting provider it doesn't work anymore and I don't get why. All links are relative and correct. Somehow the main SWF doesn't load fully, or has problems with the XML from the .php file. I'm not sure, now I only get a black box that doesn't show any of the other content it's supposed to. check it out: http://deoshermes.ath.cx/cc-common/templates/dynamiclead/dynamic_leadee.swf the XML: <?xml version="1.0" ?><dynamic_content> <item blurb="Text 1" content_url="" content_source="" content_timer="8000" content_target="_self" tab_color="0x000000" tab_border_color="0x000000" tab_arrow_color="0xFFFFFF" tab_text_color="0xFFFFFF" tab_image="/template/images/dle_TOPmay06.jpg" cycle="true" content_border_color="0x" content_bg_image="" tab_hl_color="0x000000" tab_highlight_color="0x" tab_highlight_text_color="0x" tab_highlight_image="" > </item> <item blurb="Text 2" content_timer="5000" cycle="true" content_border_color="0x" content_bg_image="" tab_hl_color="0xFFFFFF" tab_border_color="0xFFFFFF" tab_color="0xFFFFFF" tab_arrow_color="0xFFFFFF" tab_text_color="0xFFFFFF" tab_image="/template/images/dle_MIDandBOTmay06.jpg" tab_highlight_color="0x" tab_highlight_text_color="0x" tab_highlight_image="" content_url="" content_source="" content_target="_self" > </item> <item blurb="Text 3" content_timer="5000" cycle="true" content_border_color="0x" content_bg_image="" tab_hl_color="0xFFFFFF" tab_border_color="0xFFFFFF" tab_color="0xFFFFFF" tab_arrow_color="0xFFFFFF" tab_text_color="0xFFFFFF" tab_image="/template/images/dle_MIDandBOTmay06.jpg" tab_highlight_color="0x" tab_highlight_text_color="0x" tab_highlight_image="" content_url="" content_source="" content_target="_self" > </item> </dynamic_content> this works like a charm when invoking the main SWF locally. The ActionScript from the main sWF can be found at samedomain as above/Actionscript_mainmovie.txt This also seems to work great. the function formattabs (line 68) uses some javascript. Locally the main SWF functions even without this hbx file which is located /cc-common/wss/hbx.js and use in the webpage actually. I haven't got a clue what's keeping the main SWF from working properly, because all other single SWFs work properly when invoked using a direct link. And this one just isn't working... Do I maybe need to add something in the php.ini file?? Any help would be appreciated!

  • Lexer written in Javascript?

    - by Phobis
    I have a project where a user needs to define a set of instructions for a ui that is completely written in javascript. I need to have the ability to parse a string of instructions and then translate them into instructions. Is there any libraries out there for parsing that are 100% javascript? Or a generator that will generate in javascript? Thanks!

  • Inheritence and usage of dynamic_cast

    - by Mewzer
    Hello, Suppose I have 3 classes as follows (as this is an example, it will not compile!): class Base { public: Base(){} virtual ~Base(){} virtual void DoSomething() = 0; virtual void DoSomethingElse() = 0; }; class Derived1 { public: Derived1(){} virtual ~Derived1(){} virtual void DoSomething(){ ... } virtual void DoSomethingElse(){ ... } virtual void SpecialD1DoSomething{ ... } }; class Derived2 { public: Derived2(){} virtual ~Derived2(){} virtual void DoSomething(){ ... } virtual void DoSomethingElse(){ ... } virtual void SpecialD2DoSomething{ ... } }; I want to create an instance of Derived1 or Derived2 depending on some setting that is not available until run-time. As I cannot determine the derived type until run-time, then do you think the following is bad practice?... class X { public: .... void GetConfigurationValue() { .... // Get configuration setting, I need a "Derived1" b = new Derived1(); // Now I want to call the special DoSomething for Derived1 (dynamic_cast<Derived1*>(b))->SpecialD1DoSomething(); } private: Base* b; }; I have generally read that usage of dynamic_cast is bad, but as I said, I don't know which type to create until run-time. Please help!

  • Improve performance writing 10 million records to text file using windows service

    - by user1039583
    I'm fetching more than 10 millions of records from database and writing to a text file. It takes hours of time to complete this operation. Is there any option to use TPL features here? It would be great if someone could get me started implementing this with the TPL. using (FileStream fStream = new FileStream("d:\\file.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite)) { BufferedStream bStream = new BufferedStream(fStream); TextWriter writer = new StreamWriter(bStream); for (int i = 0; i < 100000000; i++) { writer.WriteLine(i); } bStream.Flush(); writer.Flush(); // empty buffer; fStream.Flush(); }

  • CodeIgniter: Where should a particular functionality go ?

    - by Samnan
    I have an application in codeigniter and a page needs to perform the following tasks 1 - controller decides which model to use based of the url and parameters 2 - controller loads the model and get the data from it 3 - controller formats the data in a particular format, depending on the items in it 4 - controller loads a common view, which will display the data (formatted data contains simple display fields) now there is a search page, which needs to do a text query against all of the possible text fields in database in all tables. It needs to show each type of data in its own formatted output on a single page as a list. The problem: The search controller can do the search, dynamically load model for each record type, and get the data from model. Problem comes when the data needs to be formatted. It looks that ideally the search controller should load another controller which will provide formatted data ... There is where it gets out of control ... My question is: What am I doing wrong? Is there any better way to do this? How would you do the same to solve the problem?

  • Can I make the compiler and the CLR ignore non implemented interfaces on my types?

    - by Thiado de Arruda
    I would like to define a type implementing a certain interface, however I would only implement it in a proxy at runtime. I can see two obstacles in this scenario : 1-Make the compiler ignore non implemented interfaces. 2-Make the CLR ignore(or at least delay) the TypeLoadException with the following description : "Method SOMEMETHOD in type SOMETYPE from assembly SOMEASSEMBLY does not have an implementation." Is something like this possible?

The problem is there are going to be some html tags indicating an image [along with its url] and videos etc in that plaintext. What is a good way to handle this identifying images and videos tags and laying corresponding images and videos along with rest of the plaintext dynamically? Thanx in advance.

  • How can I merge two Linq IEnumerable<T> queries without running them?

    - by makerofthings7
    How do I merge a List<T> of TPL-based tasks for later execution? public async IEnumerable<Task<string>> CreateTasks(){ /* stuff*/ } My assumption is .Concat() but that doesn't seem to work: void MainTestApp() // Full sample available upon request. { List<string> nothingList = new List<string>(); nothingList.Add("whatever"); cts = new CancellationTokenSource(); delayedExecution = from str in nothingList select AccessTheWebAsync("", cts.Token); delayedExecution2 = from str in nothingList select AccessTheWebAsync("1", cts.Token); delayedExecution = delayedExecution.Concat(delayedExecution2); } /// SNIP async Task AccessTheWebAsync(string nothing, CancellationToken ct) { // return a Task } I want to make sure that this won't spawn any task or evaluate anything. In fact, I suppose I'm asking "what logically executes an IQueryable to something that returns data"? Background Since I'm doing recursion and I don't want to execute this until the correct time, what is the correct way to merge the results if called multiple times? If it matters I'm thinking of running this command to launch all the tasks var AllRunningDataTasks = results.ToList(); followed by this code: while (AllRunningDataTasks.Count > 0) { // Identify the first task that completes. Task<TableResult> firstFinishedTask = await Task.WhenAny(AllRunningDataTasks); // ***Remove the selected task from the list so that you don't // process it more than once. AllRunningDataTasks.Remove(firstFinishedTask); // TODO: Await the completed task. var taskOfTableResult = await firstFinishedTask; // Todo: (doen't work) TrustState thisState = (TrustState)firstFinishedTask.AsyncState; // TODO: Update the concurrent dictionary with data // thisState.QueryStartPoint + thisState.ThingToSearchFor Interlocked.Decrement(ref thisState.RunningDirectQueries); Interlocked.Increment(ref thisState.CompletedDirectQueries); if (thisState.RunningDirectQueries == 0) { thisState.TimeCompleted = DateTime.UtcNow; } }

  • using asp.net membership provider in a dll

    - by Keith Barrows
    I've used Membership Providers in web apps over the last several years. I now have a new "request" for an internal project at work. They would like a service (not a web service) to do a quick authenticate against. Basically, exposing the ValidateUser(UserName, Password) method... I am building this in a DLL that will sit with our internal web site. What is the best approach to make this work? The DLL will not reference the web app and the web app will reference the DLL. How do I make the DLL aware of the Membership Provider? TIA PS: If this has been answered elsewhere please direct me to that... EDIT: I found an article on using ASP.NET Membership with WinForms and/or WPF applications. Unfortunately, these depend on an app.config file. A DLL appears to not use the app.config once published. If I am wrong, please set me straight! The article is here: http://aspalliance.com/1595_Client_Application_Services__Part_1.all

  • javascript - how to call a function newly added from ajax

    - by strike_noir
    I have a coding difficulty which have been asked in this forum before: Calling a JavaScript function returned from a Ajax response But I didn't find the answers quite satisfying. To be more precise of the problem I'm dealing, here is the details: I dynamically load a document (HTML and javascript) using jquery var url = 'document.php'; $('#container').load(url); And then I want to call the functions from that document.php. Due to my requirement, I don't want to call the function after the documents' loaded, but rather to call it later when I need it. Because it was dynamically loaded, the DOM doesn't recognize the functions. How to properly call this function? Thank you

  • Boost Test dynamically or statically linked?

    - by Halt
    We use Boost statically linked with our app but now I wan't to use Boost Test with an external test runner and that requires the tests themselves to link dynamically with Boost.Test through the use of the required BOOST_TEST_DYN_LINK define. Is this going to be a problem or is the way Boost Test links completely unrelated to the way the other Boost libraries are linked? Thx.

  • What prevents a user from adding controls to an ASP.NET page client side?

    - by Curtis White
    This goes back to my other question which I thought was sufficiently answers but upon reflect am not sure that it was (sorry). Backgrounder: I am generating a form dynamically. I am pulling from the database the controls. I must associate each control with a database ID which is not the user's session id. I do this currently by storing my ID in the ID for the web control with some other stuff to make it unique/clear what I am doing. On the post back, I iterate through all the controls on my web page checking for my special identifier, ie, MyGeneratedTextBox_ID_Unique. This process enables for 2 important steps, identifying the control was one I generated and also getting the ID for this input field. And, all of this works but I'm still concerned about the security of it. I do not see a security issue with showing the actual database ID's in this case, although agree it is not desirable. However, I am concerned of the following possibilities: If a user could add a nefarious control to my collection and use that for a SQL injection attack. More academic, but if a user could somehow store data for fields they do not have access too by changing the id's. I agree this is a "hack" of a way to do it. But my question is, is it a security risk and is there an 'easy' way to do it in a less hack way? I assume that only the controls that are created/instantiated on the page are added to the controls list.. thus all controls must be created server side and thus the security issue is address but just wanted to validate. Thanks again. PS: I could see adding a property for each control and encrypting the viewstate would be a little more secure.
