  • update element in knockout template which was changed by 3td party library

    - by yakov
    I have 'div' element (recaptchaDiv) in knockout template which is not bound to any observable field: <div id="recaptchaDiv"></div> On the other hand, I update this 'div' by 3rd party library. In particular, this is google recaptcha. This is my code: Recaptcha.create("[my private key]", "recaptchaDiv", { theme: "clean", callback: Recaptcha.ToTest }); And it doesn't work (I see nothing). What I know: trying on FF console: $("#recaptchaDiv").html() - it shows the expected html code, I just can't see it in the browser What I tried: to move recaptchaDiv outside of the template and it works: I can see the captcha in the browser to bind recaptchaDiv on html property: in the template: <div id="recaptchaDiv" data-bind="html: recaptcha"></div> in the model: Recaptcha.create("[my private key]", "recaptchaDiv", { theme: "clean", callback: Recaptcha.ToTest }); recaptcha($("#recaptchaDiv").html()); and it doesn't work (replacing jquery on document.getElementById doesn't help) Any help will be very much appreciated!!! Thank you in advance.

  • Java FileFilter

    - by Mr CooL
    public class DocFilter extends FileFilter { public boolean accept(File f) { if (f.isDirectory()) { return true; } String extension = Utils.getExtension(f); if (extension != null) { if (extension.equals(Utils.doc) || extension.equals(Utils.docx) ) { return true; } else { return false; } } return false; } //The description of this filter public String getDescription() { return "Just Document Files"; } } Netbeans compiler warned with the error, "No interface expected here" for above code Anyone has idea what was the problem?? I tried changing the 'extends' to 'implements', however, it didn't seem to work that way. and when I changed to implements, the following code cannot work, chooser.addChoosableFileFilter(new DocFilter()); and with this error, "method addChoosableFileFilter in class javax.swing.JFileChooser cannot be applied to given types required: javax.swing.filechooser.FileFilter" Can anyone help on this? Thanks..

  • Haskell: variant of `show` that doesn't wrap String and Char in quotes

    - by Joey Adams
    I'd like a variant of show (let's call it label) that acts just like show, except that it doesn't wrap Strings in " " or Chars in ' '. Examples: > label 5 "5" > label "hello" "hello" > label 'c' "c" I tried implementing this manually, but I ran into some walls. Here is what I tried: {-# LANGUAGE FlexibleInstances #-} {-# LANGUAGE UndecidableInstances #-} module Label where class (Show a) => Label a where label :: a -> String instance Label [Char] where label str = str instance Label Char where label c = [c] -- Default case instance Show a => Label a where label x = show x However, because the default case's class overlaps instance Label [Char] and instance Label Char, those types don't work with the label function. Is there a library function that provides this functionality? If not, is there a workaround to get the above code to work?

  • Accessing localhost via IIS 6.1 on Windows 7 very slow

    - by Ian Devlin
    (I've checked here already for similiar questions, and haven't found one that's exactly the same - hence I'm posting a new question) I'm currently running an ASP.NET application on IIS 7.0 on Windows 7. When I access this application on Internet Explorer (either 6, 7 or 8) it is incredible slow and often fails to load at all. There are messages at the bottom saying: Waiting for http://localhost/....... or sometimes waiting for about:blank (I've read that this can be a virus, but I've run all the usual checks and it's not). constantly, but it returns with the usual: "Internet Explorer cannot display the webpage" I've also tried this by using 127.0.0.1 and the machine name, with the same results. I've tried the same application on the latest Firefox, Safari, Chrome and Opera and they all work fine. I've also installed the same application on a Windows Server 2003 machine, and it all works fine via Internet Explorer. Soes anyone have any ideas why this doesn't work with Internet Explorer and yet does with other browsers?

  • Dynamic Operator Overloading on dict classes in Python

    - by Ishpeck
    I have a class that dynamically overloads basic arithmetic operators like so... import operator class IshyNum: def __init__(self, n): self.num=n self.buildArith() def arithmetic(self, other, o): return o(self.num, other) def buildArith(self): map(lambda o: setattr(self, "__%s__"%o,lambda f: self.arithmetic(f, getattr(operator, o))), ["add", "sub", "mul", "div"]) if __name__=="__main__": number=IshyNum(5) print number+5 print number/2 print number*3 print number-3 But if I change the class to inherit from the dictionary (class IshyNum(dict):) it doesn't work. I need to explicitly def __add__(self, other) or whatever in order for this to work. Why?

  • What's the best way to apply a drop shadow?

    - by jckeyes
    What is the best method for applying drop shadows? I'm working on a site right now where we have a good deal of them, however, I've been fighting to find the best method to do it. The site is pretty animation heavy so shadows need to work well with this. I tried a jQuery shadow pulgin. The shadows looked good and were easy to use but were slow and didn't work well with any animations (required lots of redrawing, very joggy). I also tried creating my own jQuery extension that wraps my element in a couple gray divs and then offsets them a little bit to give a shadow effect. This worked well. It's quick and responsive to the animation. However, it makes DOM manipulation/traversal cumbersome since everything is wrapped in these shadow divs. I know there has to be a better way but this isn't exactly my forte. Thoughts?

  • How do I list all non-system stored procedures?

    - by bubbassauro
    I want to create a query to list of all user defined stored procedures, excluding the ones that are system stored procedures, considering that: Checking the name like "sp_" doesn't work because there are user stored procedures that start with "sp_". Checking the property is_ms_shipped doesn't work because there are system stored procedures that have that flag = 0, for example: sp_alterdiagram (it is not MSShipped but appears under System Stored Procedures in SQL Server Management Studio). There must be a property, or a flag somewhere since you can see the "System Stored Procedures" in a separate folder in SQL 2005. Does anyone know? Edit: A combination of the suggestions below worked for me: select * from sys.objects O LEFT OUTER JOIN sys.extended_properties E ON O.object_id = E.major_id WHERE O.name IS NOT NULL AND ISNULL(O.is_ms_shipped, 0) = 0 AND ISNULL(E.name, '') <> 'microsoft_database_tools_support' AND O.type_desc = 'SQL_STORED_PROCEDURE' ORDER BY O.name

  • How to Schedule a Process.Start in WPF

    - by Chi Chan
    I am trying to restart an application in WPF. I tried the following: Process.Start(Application.ExecutablePath); Process.GetCurrentProcess().Kill(); And it doesn't work because the application is setup as a single instances application.

  • Changing the size of the UISearchBar TextField ?

    - by Padraig
    I have a UITableView with an Index on the side; I want to add a UISearchBar to it, but the index overlaps with the "x" to clear the search. I've noticed in the Contacts application, the textfield within the UISearchBar is resized to accommodate this, but I can't work out how to do this in my own app. I have tried the following in my viewDidLoad, but it does not seem to work. UITextField * textField = (UITextField *)[[self.search subviews] objectAtIndex:0]; CGRect r = textField.frame; [textField setFrame:CGRectMake(r.origin.x, r.origin.y, r.size.height, r.size.width-30)]; Any ideas?

  • Java: file write on finalize method

    - by sowrov
    In my understanding a singleton object will destroy only when the application is about to terminate. So in C++ I write a Singleton class to log my application and in that Singleton logger's destructor I log the time when my application was terminated. Things worked perfectly in C++. Now I want to have that same logger in Java, as in java there is no destructor so I implemented the finalize method for that singleton logger. But it seem that finalize method actually never get called. So, I add that System.runFinalizersOnExit(true); line, somewhere in my code (though I know it is deprecated) and that finalize method get called every time before termination of the app. But still there is a problem! If I try to write anything on file in that finalize method, It does not work, though System.out work without any problem! :( Can you guys help me on this problem? Here is a sample code of what I am try to do: Singleton Logger Class: public class MyLogger { FileWriter writer; private MyLogger() { try { this.writer = new FileWriter("log.txt"); } catch (IOException ex) { } } public static MyLogger getInstance() { return MyLoggerHolder.INSTANCE; } private static class MyLoggerHolder { private static final MyLogger INSTANCE = new MyLogger(); } @Override protected void finalize () { try { super.finalize(); System.out.println("Here"); //worked correctly. this.writer.write(new Date().toString()+System.getProperty("line.separator")); this.writer.write("End"); this.writer.flush(); //does not work! this.writer.close(); } catch (Throwable ex) { } } public synchronized void log(String str) { try { this.writer.write(new Date().toString()+System.getProperty("line.separator")); this.writer.write(str+"\n"); this.writer.flush(); } catch (IOException ex) { } } } Main: public class Main { public static void main(String[] args) { System.runFinalizersOnExit(true); MyLogger logger = MyLogger.getInstance(); logger.log("test"); } }

  • .NET WebService IPC - Should it be done to minimise some expensive operations?

    - by Kyle
    I'm looking at a few different approaches to a problem: Client requests work, some stuff gets done, and a result (ok/error) is returned. A .NET web service definitely seems like the way to go, my only issue is that the "stuff" will involve building up and tearing down a session for each request. Does abstracting the "stuff" out to an app (which would keep a single session active, and process the request from the web service) seem like the right way to go? (and if so, what communication method) The work time is negligible, my concern is the hammering the transaction servers in question will probably get if I create/drop a session for each job. Is some form of IPC or socket based communication a feasible solution here? Thoughts/comments/experiences much appreciated. Edit: After a bit more research, it seems like hosting a WCF service in a Windows Service is probably a better way to go...

  • Multiple Class in JDO Query

    - by Dan Delgado
    Hello, I'm currently developing in GAE and I have to query like this using JDO: SELECT table1.column1, table2.column2 FROM table1, table2 WHERE table1.column1 = table2.column1; I tried this one but it won't work: String query = "select from "+Assessment.class.getName()+ "a, "+ Project.class.getName()+" p where a.projectId == p.id && p.owner=='"+owner+"'"; Is this valid or this really isn't supported yet? If this is valid, why is it not working then? If it isn't, what should I do to make this work? Thank you!

  • Is the use of a proxy required to consume a WCF service?

    - by Tone
    I have a WCF Service that I want my client to be able to consume from IIS without going through a proxy. The client was consuming asmx service in vbscript using the htc behavior: <div id="oWSInterop" style="behavior:url(webservice.htc)"></div> oWSInterop.useService "http://localhost/WSInteroperability.asmx", "WSInteroperability" Set response = oWSInterop.WSInteroperability.callServiceSync("BuildSingleDoc", 1002, 19499, XMLEncode(sAdditionalDetail)) So basically I just want to make this work with making as few changes as possible on the existing client. Am I forced to use a proxy when consuming a WCF service? I do understand the benefits of a proxy and am not opposed to using it for most other client implementations, but in this case I'm not sure I have the time to deal with it on the client - i just want it to work the way it has been with only the endpoint changing.

  • Overriding rubies spaceship operator <=>

    - by ericsteen1
    I am trying to override rubies <= (spaceship) operator to sort apples and oranges so that apples come first sorted by weight, and oranges second, sorted by sweetness. Like so: module Fruity attr_accessor :weight, :sweetness def <=>(other) # use Array#<=> to compare the attributes [self.weight, self.sweetness] <=> [other.weight, other.sweetness] end include Comparable end class Apple include Fruity def initialize(w) self.weight = w end end class Orange include Fruity def initialize(s) self.sweetness = s end end fruits = [Apple.new(2),Orange.new(4),Apple.new(6),Orange.new(9),Apple.new(1),Orange.new(22)] p fruits #should work? p fruits.sort But this does not work, can someone tell what I am doing wrong here, or a better way to do this?

  • How do I can linux flock command to prevent another root process deleting a file?

    - by Danmaxis
    Hello there, I would like to prevent one of my root process from deleting a certaing file. So I came across the flock command, it seems to fit my need, but I didnt get its sintax. If I only indicate a shared lock, it doesnt work: flock -s "./file.xml" If I add a timeout parameter, it still doesnt work flock -s -w5 "./file.xml" It seems that way, it fits in flock [-sxun][-w #] fd# way. (What is this fd# parameter?) So, I tried the flock [-sxon][-w #] file [-c] command Using flock -s -w5 "./file.xml" -c "tail -3 ./file.xml" and it worked, tail command at ./file.xml was executed. But I would like to know, does the lock end after the command or does it last 5 seconds after the end of the command execution? My main question is, how can I prevent another root process deleting a file in linux?

  • preserving history when using mercurial ontop of clearcase

    - by Arthur Ulfeldt
    I work in a ClearCase shop and CC does a good job of integrating the team's work though our code review process prevents me from using it to track my daily changes. Creating an hg repository on top of my CC view works really well. I can track my changes and easily make backups on the file server, produce diffs for people etc. This is all well and good until I move to a new CC view and have to leave my history behind. I would love to be able to ?pull? my previous history in and have everything that's different in the new view show up as the latest change set.

  • hyperlink in firefox to windows share

    - by Eds
    I am having trouble creating a hyperlink to a windows share, that works correctly in firefox and IE9. The original line was this: <a href="\\10.1.3.33\sharename\filename.txt" target="_new">Link</a> This works correctly in IE9, andopens the file as you would expect. However, this does not seem to work in firefox, as it just appends the above to the root directory, so it ends up looking in: /\10.1.3.33/sharename/filename I have tried as someone suggested and appending file:// to the pathname, but this does not seem to load anything in firefox, but does work in IE. Can anyone advise on what I should be using the get a link to a network share working in all browsers? Many thanks, Eds

  • Why does adding a reference to project targeting .NET Framework 4.0 fail?

    - by Malcolm Post
    We have two projects that are both class libraries. Project 1 is a VS 2008 project and targets the .NET Framework 3.5. Project 2 is a VS 2010 (release candidate) project that targets the .NET Framework 4.0. When I try to add a reference to Project 2 in Project 1, it fails with a less than informative error message. I know that if I change the target Framework for Project 2 to 3.5, then adding the reference will work. My question is, if I don't change the target frameworks, but convert Project 1 to VS 2010, will the referencing work? Stated another way, is there some inherent incompatiblity between class libraries targeting different framework versions, or is it failing for me because VS 2008 doesn't know about the 4.0 framework?

  • How to change button's image in visual c++ at run time?

    - by karikari
    After trying and error for many times, I decided to ask here. My objective is I wanted to change the feature of my IE toolbar button. The button is firstly setup by IE at IE startup using the function CRebarHandler::onSetRedraw and CRebarHandler::setButtonMenu2(). And then, I create a call from another cpp file, to call CRebarHandler::setButtonMenu2(). I intent to change just the button's image. I assigned the ID of the image correctly. But somehow it does not work. When I put other code inside this function,like a code for writing to file, it is proven work. Means, it is properly being called from the other file. But the thing is, the code for the button inside CRebarHandler::setButtonMenu2() seems does not work. Need help. Here is the code I am working on (I modify John Lister's button code): LRESULT CRebarHandler::onSetRedraw(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled){ bHandled=false; if (m_ieVer==6){ if (!m_hWndToolbar) scanForToolbarSlow(); if (m_hWndToolbar){ findButton(m_hWndToolbar); if (m_buttonID>0) setButtonMenu(); } } return S_OK; } void CRebarHandler::setButtonMenu(){ HIMAGELIST hImageList = ImageList_Create(32, 32,ILC_COLOR16 | ILC_MASK,1, 0); HINSTANCE module = _AtlBaseModule.GetResourceInstance(); TBBUTTONINFO inf; inf.cbSize=sizeof(inf); inf.dwMask = TBIF_IMAGE; char psBuffer[128]; FILE *pPipe; float f = 0; pPipe = _popen("javaw -jar c:\\simmetrics.jar c:\\chtml.txt c:\\thtml.txt", "rt" ); char* p = fgets(psBuffer, 128, pPipe); std::istringstream iss(p); iss >> f; if (f > 0.9) { inf.iImage = 1; SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); iss.clear(); f = 0; } else { inf.iImage = 2; SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); iss.clear(); f = 0; } iss.clear(); f = 0; } void CRebarHandler::setButtonMenu2(){ TBBUTTONINFO inf; inf.cbSize=sizeof(inf); inf.dwMask = TBIF_IMAGE; inf.iImage = 1; //green SendMessage(NULL, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); }

  • Is there a free code coverage tool suitable for use with .NET 4 and NUnit?

    - by Damian Powell
    Is there a free code coverage tool suitable for use with .NET 4 and NUnit that runs from the command line (and is thus suitable for use on a build server)? Please note that any tools that require editions of Visual Studio higher than Professional are not appropriate in this case. I am asking this question because I can't get NCover 1.5.8 to work with NUnit 2.5.5 on a .NET 4 C# app. I can run the unit tests, and I can generate a Coverage.Xml file, but it is empty - it contains no sequence points. After a lot of research, I have concluded that this is because NCover 1.5.8 simply doesn't work with .NET 4. However, if you know better, please feel free to answer this question from another user.

  • Single OpenID Across Sub-Domains

    - by rockinthesixstring
    I'm using OpenID much the same as here on StackOverflow to authenticate my users. What I really need to be able to do though is have that OpenID work across all sub-domains of my site. The site behaves much the same as Kijiji in that each region has it's own subdomain calgary.example.com toronto.example.com vancouver.example.com etc When a user logs into "calgary" and later logs into "toronto", they will be forced to "give permission" at the provider, thus resulting in a new OpenID and resulting also in a new login. My app "can" have multiple OpenID's under one account, but that would become cumbersome to manage. Is there a way to have the provider link up to the top level domain and subsequently work across all sub-domains? I'm using DotNetOpenAuth.

  • Linq query challenge - can this be done?

    - by vdh_ant
    My table structure is as follows: Person 1-M PesonAddress Person 1-M PesonPhone Person 1-M PesonEmail Person 1-M Contract Contract M-M Program Contract M-1 Organization At the end of this query I need a populated object graph where each person has their: PesonAddress's PesonPhone's PesonEmail's PesonPhone's Contract's - and this has its respective Program's Now I had the following query and I thought that it was working great, but it has a couple of problems: from people in ctx.People.Include("PersonAddress") .Include("PersonLandline") .Include("PersonMobile") .Include("PersonEmail") .Include("Contract") .Include("Contract.Program") where people.Contract.Any( contract => (param.OrganizationId == contract.OrganizationId) && contract.Program.Any( contractProgram => (param.ProgramId == contractProgram.ProgramId))) select people; The problem is that it filters the person to the criteria but not the Contracts or the Contract's Programs. It brings back all Contracts that each person has not just the ones that have an OrganizationId of x and the same goes for each of those Contract's Programs respectively. What I want is only the people that have at least one contract with an OrgId of x with and where that contract has a Program with the Id of y... and for the object graph that is returned to have only the contracts that match and programs within that contract that match. I kinda understand why its not working, but I don't know how to change it so it is working... This is my attempt thus far: from people in ctx.People.Include("PersonAddress") .Include("PersonLandline") .Include("PersonMobile") .Include("PersonEmail") .Include("Contract") .Include("Contract.Program") let currentContracts = from contract in people.Contract where (param.OrganizationId == contract.OrganizationId) select contract let currentContractPrograms = from contractProgram in currentContracts let temp = from x in contractProgram.Program where (param.ProgramId == contractProgram.ProgramId) select x where temp.Any() select temp where currentContracts.Any() && currentContractPrograms.Any() select new Person { PersonId = people.PersonId, FirstName = people.FirstName, ..., ...., MiddleName = people.MiddleName, Surname = people.Surname, ..., ...., Gender = people.Gender, DateOfBirth = people.DateOfBirth, ..., ...., Contract = currentContracts, ... }; //This doesn't work But this has several problems (where the Person type is an EF object): I am left to do the mapping by myself, which in this case there is quite a lot to map When ever I try to map a list to a property (i.e. Scholarship = currentScholarships) it says I can't because IEnumerable is trying to be cast to EntityCollection Include doesn't work Hence how do I get this to work. Keeping in mind that I am trying to do this as a compiled query so I think that means anonymous types are out.

  • Treat a void function as a value

    - by Brendan Long
    I'm writing some terrible, terrible code, and I need a way to put a free() in the middle of a statement. The actual code is: int main(){ return printf("%s", isPalindrome(fgets(malloc(1000), 1000, stdin))?"Yes!\n":"No!\n") >= 0; // leak 1000 bytes of memory } I was using alloca(), but I can't be sure that will actually work on my target computer. My problem is that free returns void, so my code has this error message: error: void value not ignored as it ought to be The obvious idea I had was: int myfree(char *p){ free(p); return 0; } Which is nice in that it makes the code even more unreadable, but I'd prefer not to add another function. I also briefly tried treating free() as a function pointer, but I don't know if that would work, and I don't know enough about C to do it properly. Note: I know this is a terrible idea. Don't try this at home kids.
