  • Howto get iframe linking to internal document source using javascript/jQuery?

    - by Tom
    Hi there, I have an iframe with id "appframe", the source is page.html and it's on the same server. I want to get the source of the page using jQuery. alert($("#appframe").contents().find("html").html()); returns <head></head><body></body> even though the document does not contain those tags, it only contains "Default page", so that is exactly what it should return. Any idea how to get the right source script of the whole document using jQuery? Eg. if the document would be "test" then that is exactly what it should return. Please note: I did ask this before a few weeks ago. Unfortunately, I got no solving answer. Because of my lower reputation (~85), I can not request a bounty... This doesn't make much sense to me. Anyway, it forced me to repost this question.

  • How do I detect bots programatically

    - by Tom
    we have a situation where we log visits and visitors on page hits and bots are clogging up our database. We can't use captcha or other techniques like that because this is before we even ask for human input, basically we are logging page hits and we would like to only log page hits by humans. Is there a list of known bot IP out there? Does checking known bot user-agents work?

  • C++ design question, container of instances and pointers

    - by Tom
    Hi all, Im wondering something. I have class Polygon, which composes a vector of Line (another class here) class Polygon { std::vector<Line> lines; public: const_iterator begin() const; const_iterator end() const; } On the other hand, I have a function, that calculates a vector of pointers to lines, and based on those lines, should return a pointer to a Polygon. Polygon* foo(Polygon& p){ std::vector<Line> lines = bar (p.begin(),p.end()); return new Polygon(lines); } Here's the question: I can always add a Polygon (vector Is there a better way that dereferencing each element of the vector and assigning it to the existing vector container? //for line in vector<Line*> v //vcopy is an instance of vector<Line> vcopy.push_back(*(v.at(i)) I think not, but I dont really like that approach. Hopefully, I will be able to convince the author of the class to change it, but I cant base my coding right now to that fact (and i'm scared of a performance hit). Thanks in advance.

  • C++ vector<T>::iterator operator +

    - by Tom
    Hi, Im holding an iterator that points to an element of a vector, and I would like to compare it to the next element of the vector. Here is what I have Class Point{ public: float x,y; } //Somewhere in my code I do this vector<Point> points = line.getPoints(); foo (points.begin(),points.end()); where foo is: void foo (Vector<Point>::iterator begin,Vector<Point>::iterator end) { std::Vector<Point>::iterator current = begin; for(;current!=end-1;++current) { std::Vector<Point>::iterator next = current + 1; //Compare between current and next. } } I thought that this would work, but current + 1 is not giving me the next element of the vector. I though operator+ was the way to go, but doesnt seem so. Is there a workaround on this? THanks

  • How to pop items from a collection in Java?

    - by Tom Brito
    Is there a method in JDK or apache commons to "pop" a list of elements from a java.util.List? I mean, remove the list of elements and return it, like this method: public Collection pop(Collection elementsToPop, Collection elements) { Collection popped = new ArrayList(); for (Object object : elementsToPop) { if (elements.contains(object)) { elements.remove(object); popped.add(object); } } return popped; }

  • How can I write to a single xml file from two programs at the same time?

    - by Tom Bushell
    We recently started working with XML files, after many years of experience with the old INI files. My coworker found some CodeProject sample code that uses System.Xml.XmlDocument.Save. We are getting exceptions when two programs try to write to the same file at the same time. System.IO.IOException: The process cannot access the file 'C:\Test.xml' because it is being used by another process. This seems obvious in hindsight, but we had not anticipated it because accessing INI files via the Win32 API does not have this limitation. I assume there's some arbitration done by the Win32 calls that work at a higher level than the the XmlDocument.Save method. I'm hoping there are higher level XML routines somewhere in the .Net library that work similarily to the Win32 functions, but don't know where to start looking. Or maybe we can set up our file access permissions to allow multiple programs to write to the same file? Time is short (like almost all SW projects), and if we can't find a solution quickly, we'll have to hold our noses and go back to INI files.

  • C++ Adding 2 arrays together quickly

    - by Tom Gullen
    Hello! Given the arrays: int canvas[10][10]; int addon[10][10]; Where all the values range from 0 - 100, what is the fastest way in C++ to add those two arrays so each cell in canvas equals itself plus the corresponding cell value in addon. IE, I want to achieve something like: canvas += another; So if canvas[0][0] =3 and addon[0][0] = 2 then canvas[0][0] = 5 Speed is essential here as I am writing a very simple program to brute force a knapsack type problem and there will be tens of millions of combinations.

  • UIWebView doesn't scroll to the bottom of the webpage loaded/created

    - by tom
    I have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?

  • Load two instances of the same DLL in Delphi

    - by Tom
    Here's my problem: I would like to create two separate instances of the same DLL. The following doesn't work because Handle1 and Handle2 will get the same address Handle1 := LoadLibrary('mydll.dll'); Handle2 := LoadLibrary('mydll.dll'); The following works, but I have to make a copy of the DLL and rename it to something else (which seems a bit silly) Handle1 := LoadLibrary('mydll.dll'); Handle2 := LoadLibrary('mydll2.dll'); Is there a way to have only one DLL file, but load several instances of it?

  • click handler after using Ajax

    - by Tom
    I have a site that plays a stream. I perform an AJAX call to the server once a person presses a button. <input type="submit" class="play" data-type="<?php echo $result_cameras[$i]["camera_type"]; ?>" data-hash="<?php echo $result_cameras[$i]["camera_hash"]; ?>" value="<?php echo $result_cameras[$i]["camera_name"]; ?>"> This prints out a bunch of buttons that the user can select. This is processed by the following code: <script> $(document).ready(function(){ $(".play").click(function(){ var camerahash = $(this).data('hash'); var cameratype = $(this).data('type'); function doAjax(){ $.ajax({ url: 'index.php?option=streaming&task=playstream&id_hash=<?php echo $id_hash; ?>&camera_hash='+camerahash+'&format=raw', success: function(data) { if (data == 'Initializing...please wait') { $('#quote p').html(data); setTimeout(doAjax, 2000); } else { if (cameratype == "WEBCAM" && data == 'Stream is ready...') { $('#quote p').html(data); window.location = 'rtsp://<?php echo DEVSTREAMWEB; ?>/<?php echo $session_id;?>/'+camerahash; } else if (cameratype == "AXIS" && data == 'Stream is ready...') { $('#quote p').html(data); window.location = 'rtsp://<?php echo DEVSTREAMIP; ?>/<?php echo $session_id;?>/'+camerahash; } else { $('#quote p').html(data); } } } }); } doAjax(); }); }); </script> The server returns the messages such as Stream is ready.... My problem is that everything is working great except on additional button clicks. Specifically when they get success (video plays) and they exit back out, they don't get any other messages if they click another button. It is as if the click event is not triggered. Do I need to be doing something to the click handler to respond?

  • WindowsFormsApplicationBase SplashScreen makes login form ignore keypresses until I click on it - how to debug?

    - by Tom Bushell
    My WinForms app has a simple modal login form, invoked at startup via ShowDialog(). When I run from inside Visual Studio, everything works fine. I can just type in my User ID, hit the Enter key, and get logged in. But when I run a release build directly, everything looks normal (the login form is active, there's a blinking cursor in the User ID MaskedEditBox), but all keypresses are ignored until I click somewhere on the login form. Very annoying if you are used to doing everything from the keyboard. I've tried to trace through the event handlers, and to set the focus directly with code, to no avail. Any suggestions how to debug this (outside of Visual Studio), or failing that - a possible workaround? Edit Here's the calling code, in my Main Form: private void OfeMainForm_Shown(object sender, EventArgs e) { OperatorLogon(); } private void OperatorLogon() { // Modal dialogs should be in a "using" block for proper disposal using (var logonForm = new C21CfrLogOnForm()) { var dr = logonForm.ShowDialog(this); if (dr == DialogResult.OK) SaveOperatorId(logonForm.OperatorId); else Application.Exit(); } } Edit 2 Didn't think this was relevant, but I'm using Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase for it's splash screen and SingleInstanceController support. I just commented out the splash screen code, and the problem has disappeared. So that's opened up a whole new line of inquiry... Edit 3 Changed title to reflect better understanding of the problem

  • PHP: How to check for response code?

    - by Tom
    Hi, I'm a relative PHP newbie implementing a PayPal IPN listener and all seems to be working fine, except I dont really know how to check for a response code. I've tried something ugly with cURL but it doesn't work at all (I'm not understanding cURL). I've tried this piece of code that I grabbed from somewhere on the net: $fp = fsockopen('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30); $response_headers = get_headers($fp); $response_code = (int)substr($headers[0], 9, 3); ... but it's not working (returns $response_code = 0). So right now, I'm debugging my IPN code without checking for a Response 200. Can anyone more experienced advise me on what's the proper/simple way to check this? Thanks

  • Possible to add an EventListener to a function for Actionscript 3?

    - by Tom
    I'm trying to setup something like Aspect Oriented Programming in Actionscript 3, basically the only thing I need to be able to do is something like this: SomeClass.getMethod("methodName").addEventListener(afterMethodExecuted, function() { //run code }); This way I can run code after (or before) any method in any class has run, allowing numerous new possibilities. How should I implement this?

  • simulate to change the background color when click the link

    - by tom
    I have the following HTML and the java script below to simulate the background color change when the link block is clicked, but it doesn't seem to work. Any reason why? If I have only the onmousedown event handled, the background color will be changed to blue for sure. But if both onmousedown and onmouseup are handled, nothing would change visually. note... function changeColorOnMouseDown() { document.getElementById('note').style.background='blue'; } function changeColorOnMouseUp() { document.getElementById('note').style.background='#d8dde7'; }

  • Alternatives to FastDateFormat for efficient date parsing?

    - by Tom Tucker
    Well aware of performance and thread issues with SimpleDateFormat, I decided to go with FastDateFormat, until I realized that FastDateFormat is for formatting only, no parsing! Is there an alternative to FastDateFormat, that is ready to use out of the box and much faster than SimpleDateFormat? I believe FastDateFormat is one of the faster ones, so anything that is about as fast would do. Just curious , any idea why FastDateFormat does not support parsing? Doesn't it seriously limit its use? Thanks! EDIT Holy crap, I just left a comment and that literally REMOVED a good answer! This appears a serious bug on stackoverflow!

  • iPhone SDK: problem managing orientation with multiple view controllers.

    - by Tom
    I'm trying to build an iPhone application that has two subviews in the main window. Each view has its own UIViewController subclass associated with it. Also, within each controller's implementation, I've added the following method: -(BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { return YES; } Thus, I would expect both of the views to respond to changes in orientation. However, this is not the case. Only the first view added to the app's main window responds to orientation. (If I swap the order the views are added, then only the other view responds. In other words, either will work--but only one at a time.) Why is this? Is it not possible to handle the orientation changes of more than one view? Thanks! EDIT: Someone else had this question, so I'm copying my solution here: I was able to address this issue by providing a root view and a root view controller with the method "shouldAutoRotate..." and adding my other views as subviews to the root view. The subviews inherit the auto-rotating behavior, and their associated view controllers shouldn't need to override "shouldAutoRotate..."

  • DeferWindowPos and SWP_SHOWWINDOW/SWP_HIDEWINDOW

    - by Tom Bell
    I am writing a virtual desktop application which utilises the DeferWindowPos API functions. The current method I am using is moving the windows off the screen if they're not on the current virtual desktop. However I know wish to also hide the windows that are off-screen so they do not appear on the task bar. I have attempted this by also passing SWP_SHOWWINDOW/SWP_HIDEWINDOW to the DeferWindowPos() calls. I have read a few sites regarding this and one of them suggested that if SWP_SHOWWINDOW/SWP_HIDEWINDOW are passed, then the window will only show or hide, and no reposition. Can anyone confirm this, or am I doing something wrong?

  • Defined outlets, connected them, they all returns (null)

    - by Tom
    Hi! I'm trying to play with a WebView. I made an outlet: IBOutlet UIWebView *browser; Defined it as a property: @property (nonatomic, retain) IBOutlet UIWebView *browser; Synthethized it: @synthesize browser; Finally, I connected it in Interface Builder, really it is. Then I try to do something with it i.e.: [browser loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; Or also: Etape *etape = [[Etape alloc] init]; NSString *html = [etape generateHTMLforEtape:[current_etape objectAtIndex:0]]; [browser loadHTMLString:html baseURL:nil]; [etape release]; I get no errors, I tried to Build & Analyse, no notices or warnings or errors.. I've been searching for one whole day, please help me :/ Thanks a lot! EDIT: Here's screenshots of my connections for my WebView: EDIT: That is how I call the view: DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]]; dvController.workflow_id = parent_id; Etape *etape = [[Etape alloc] init]; dvController.etapes = [etape getEtapes:parent_id]; [etape release]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release];
