  • cURL + HTTP_POST, keep getting 500 error. Has no idea?

    - by mysqllearner
    Okay, I want to make a HTTP_POST using cURL to a SSL site. I already imported the certificate to my server. This is my code: $url = "https://www.xxx.xxx"; $post = "";# all data that going to send $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0'); $exe = curl_exec($ch); $getInfo = curl_getinfo($ch); if ($exe === false) { $output = "Error in sending"; if (curl_error($ch)){ $output .= "\n". curl_error($ch); } } else if($geInfo['http_code'] != 777){ $output = "No data returned. Error: " . $geInfo['http_code']; if (curl_error($ch)){ $output .= "\n". curl_error($ch); } } curl_close($c); echo $output; It keep returned "500". Based on w3schools, 500 means Internal Server Error. Is my server having problem? How to solve/troubleshoot this?

  • Intermittent apt-get 'no installation candidate' error on fabric deploy

    - by jberryman
    I'm experiencing a strange issue with a fabric script I'm using to bootstrap a server on EC2. I launch a stock Ubuntu 12.04 AMI, wait for it to start, then proceed with: with settings(host_string="ubuntu@%s" % i.dns_name, connection_attempts=30): sudo('apt-get -qy update') sudo('apt-get -qy install --no-install-recommends mdadm') # don't install postfix #etc... The apt-get update appears to run fine and gives no errors, however (2/3 of the time or so) installing mdadm throws a "no installation candidate" error. When I ssh into the server and run apt-get install mdadm I get the same error. Running apt-get update by hand, then the package installs fine. Any ideas on what might be happening, or ideas for debugging?

  • MFC (C++) CDialog DoModal() not working as expected

    - by krebstar
    Hi, I have a plugin that is loaded by this application.. This plugin calls some dialog boxes with DoModal(). I'm expecting these dialog boxes to function like this: If I click on the application window behind the dialog box, the dialog box flashes and does not allow the application to be in focus. However, in one of the other dialog boxes, called with DoModal(), if I click on the application window, it doesn't do the flashing thing, and after a while the application's close/minimize buttons become active (well, just the color). They're not really active and the window turns somewhat white and the title bar says (Not Responding)... What could possibly be wrong and how do I fix it? I've tried setting the dialog box's properties to System Modal: True, and Set Foreground: True but it doesn't seem to work.. :( Thanks.. EDIT: I'd like to note that the in the Windows taskbar, there is only one entry for the application for the correct behavior, but when the dialog box with the incorrect behavior is launched, another "window" is launched.. So it looks like (Application)(Dialog box title).. The effect I'm trying to achieve is just (Application)..

  • Partial template specialization for more than one typename

    - by Matt Joiner
    In the following code, I want to consider functions (Ops) that have void return to instead be considered to return true. The type Retval, and the return value of Op are always matching. I'm not able to discriminate using the type traits shown here, and attempts to create a partial template specialization based on Retval have failed due the presence of the other template variables, Op and Args. How do I specialize only some variables in a template specialization without getting errors? Is there any other way to alter behaviour based on the return type of Op? template <typename Retval, typename Op, typename... Args> Retval single_op_wrapper( Retval const failval, char const *const opname, Op const op, Cpfs &cpfs, Args... args) { try { CallContext callctx(cpfs, opname); Retval retval; if (std::is_same<bool, Retval>::value) { (callctx.*op)(args...); retval = true; } else { retval = (callctx.*op)(args...); } assert(retval != failval); callctx.commit(cpfs); return retval; } catch (CpfsError const &exc) { cpfs_errno_set(exc.fserrno); LOGF(Info, "Failed with %s", cpfs_errno_str(exc.fserrno)); } return failval; }

  • Refactor link to show/hide a table row

    - by abatishchev
    I have a table with row which cab be hidden by user. It's implemented this way: Markup: <table> <tr> <td> <table style="margin-left: auto; text-align: right;"> <tr> <td class="stats-hide"> <a href="#" onclick="hideStats();">Hide</a> </td> <td class="stats-show" style="display: none;"> <a href="#" onclick="showStats();">Show</a> </td> </tr> </table> </td> </tr> <tr class="stats-hide"> <td> <!-- data --> </td> </tr> </table> And jQuery code: <script type="text/javascript" language="javascript"> function hideStats() { hideControls(true, $('.stats-hide')); hideControls(false, $('.stats-show')); } function showStats() { hideControls(false, $('.stats-hide')); hideControls(true, $('.stats-show')); } function hideControls(value, arr) { $(arr).each(function () { if (value) { $(this).hide(); } else { $(this).show(); } }); } </script> How to implement the same behavior with one, single link and one, probably, CSS class? My idea - store somewhere a boolean variable and toggle controls visibility relatively to this variable. Are there more?

  • Why are there so few Wireless N Dual Band adapter PCI cards, only USB adapters instead?

    - by daiphoenix
    There has been several Wireless N Dual Band routers/APs out in the market for quite some time now, and there are several Wireless N Dual Band USB adapters out there. But as for PCI/PCI-X card adapters, there seems to be only one (the Linksys WMP600N). Why is that? I find it very strange. Is it because the USB adapters are easier to install, and can be used on multiple computers? But if so, why isn't it the same case with single band (2.4 Ghz) wireless N adapters? Because for these ones there as many PCI card adapters as there are USB adapters. Also, can the USB adapters, despite the lack of external antenna, offer the same level of performance as a card with external antennas?

  • Downloading content greater than 2000 bytes from local network hangs in browser on Windows XP

    - by artplastika
    We have web application that runs under Tomcat in a local network. Our customers experience strange problem using this web application. Let's say Tomcat server runs on host1 and we open webapp URL in browser on host2. Any browser on host 2 starts opening page and downloading of content "hangs" for hours. We've made bunch of experiments and found that any content larger than 2000 bytes makes browser request hang. Tried in Internet Explorer 8, Opera 12, Firefox. At the same time if user opens website from internet, it works. Opening webapp from the same host1 where Tomcat is running works normally. Local network is organized with D-Link DGS-3120-48TC switch. Additional info. During experiments we've noticed XP Tweaker installed on hosts. Network settings from that tool: MTU is manually set to 1500 RWIN = 14600 Support of TCP frames larger than 64 KB is on Time to Live = 32 SACK is on

  • 2D Histogram in R: Converting from Count to Frequency within a Column

    - by Jac
    Would appreciate help with generating a 2D histogram of frequencies, where frequencies are calculated within a column. My main issue: converting from counts to column based frequency. Here's my starting code: # expected packages library(ggplot2) library(plyr) # generate example data corresponding to expected data input x_data = sample(101:200,10000, replace = TRUE) y_data = sample(1:100,10000, replace = TRUE) my_set = data.frame(x_data,y_data) # define x and y interval cut points x_seq = seq(100,200,10) y_seq = seq(0,100,10) # label samples as belonging within x and y intervals my_set$x_interval = cut(my_set$x_data,x_seq) my_set$y_interval = cut(my_set$y_data,y_seq) # determine count for each x,y block xy_df = ddply(my_set, c("x_interval","y_interval"),"nrow") # still need to convert for use with dplyr # convert from count to frequency based on formula: freq = count/sum(count in given x interval) ################ TRYING TO FIGURE OUT ################# # plot results fig_count <- ggplot(xy_df, aes(x = x_interval, y = y_interval)) + geom_tile(aes(fill = nrow)) # count fig_freq <- ggplot(xy_df, aes(x = x_interval, y = y_interval)) + geom_tile(aes(fill = freq)) # frequency I would appreciate any help in how to calculate the frequency within a column. Thanks! jac EDIT: I think the solution will require the following steps 1) Calculate and store overall counts for each x-interval factor 2) Divide the individual bin count by its corresponding x-interval factor count to obtain frequency. Not sure how to carry this out though. .

  • Cannot connect to IIS 7 from localhost

    - by Wout
    I cannot connect to the local IIS 7 using "http://localhost" in IE. "http://127.0.0.1" doesn't work either. The strange thing is that if I add a binding on e.g. port 81, then I can reach "http://localhost:81". Also turning off the firewall on the local machine doesn't help. The site is reachable from the internet. The local requests don't seem to hit IIS (no entries in the IIS log files). IIS is hosted on Windows Server 2008 R2 from behind a hardware firewall device. Note that I'm a programmer, not a network administrator, so I'm having a hard time trouble shooting this.

  • Video problem with Windows 7 Games

    - by Jordan 1GT
    I have a Dell xps M1330 which originally ran Vista, but I upgraded to Windows 7. When I try to run a Win 7 game like spider solitaire I receive the following message: "The game is running in software rendering mode. Hardware acceleration is either disabled or not supported by your video card driver which could slow down game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on." I confirmed that hardware acceleration is turned on. When I go to Dell's site, I'm told there is no later video driver. When I run the game it runs very choppy. I wouldn't care, but I loaded a .pptx file which is doing strange things in normal view and I suspect may be related to the same video problem. Any ideas?

  • Add class to textbox when invalid, using .Net Validators

    - by CoreyT
    I'm working on a multipage form in .Net using AJAX (UpdatePanels). I am stuck right now trying to get a class added to the textbox that is invalid to basically highlight it red. I found a sample online using this code: $("span.invalid").bind("DOMAttrModified propertychange", function (e) { // Exit early if IE because it throws this event lots more if (e.originalEvent.propertyName && e.originalEvent.propertyName != "isvalid") return; var controlToValidate = $("#" + this.controltovalidate); var validators = controlToValidate.attr("Validators"); if (validators == null) return; var isValid = true; $(validators).each(function () { if (this.isvalid !== true) { isValid = false; } }); if (isValid) { controlToValidate.removeClass("invalid"); } else { controlToValidate.addClass("invalid"); } }); That works perfectly, in IE only. For some reason this code does not ever fire in Firefox. I've looked up the DOMAttrModified event and it sounds like this should work in Firefox, hence it being in the code. I must be missing something though because it does not work. I'm open to other solutions for what I am trying to accomplish here if anyone has something good. Basically the form is 3 pages right now. Page 1 has a variable number of fields that require validation. It could be 5, or 13 fields, based on a checkbox. Page 2 has another set of fields that need to be validated separately. Obviously when I am on page 1 it should not try to validate page 2, and vice versa. Pleas help with either some help to fix the code I have, or an alternative.

  • For loop index out of range ArgumentOutOfRangeException when multithreading

    I'm getting some strange behavior... when I iterate over the dummyText List in the ThreadTest method I get an index out of range exception (ArgumentOutOfRangeException), but if I remove the threads and I just print out the text, then everything works fine.

  • Jquery Sorting by Letter

    - by Batfan
    I am using jquery to sort through a group of paragraph tags (kudos to Aaron Harun). It pulls the value "letter" (a letter) from the url string and displays only paragraphs that start with that letter. It hides all others and also consolidates the list so that there are no duplicates showing. See the code: var letter = '<?php echo(strlen($_GET['letter']) == 1) ? $_GET['letter'] : ''; ?>' function finish(){ var found_first = []; jQuery('p').each(function(){ if(jQuery(this).text().substr(0,1).toUpperCase() == letter){ if(found_first[jQuery(this).text()] != true){ jQuery(this).addClass('current-series'); found_first[jQuery(this).text()] = true; }else{ jQuery(this).hide(); } } else{ jQuery(this).hide();} }) } Been working with this all day and I have 2 Questions on this: Is there a way to get it to ignore the word 'The', if it's first? For example, if a paragraph starts with 'The Amazing', I would like it to show up on the 'A' page, not the 'T' page, like it currently is. Is there a way to have a single page for (all) numbers? For example, the url to the page would be something similar to domain.com/index.php?letter=0 and this would show only the paragraph tags that start with a number, any number. I can currently do this with single numbers but, I would like 1 page for all numbers.

  • Two domains hosted on the same server with different root folder shows up the same homepage

    - by emaillenin
    I have hosted two domains from GoDaddy at Linode VPS. They are mobiletoast.com and lesseltechnologies.com Thought the latter site has a separate index folder, whenever I navigate to it, I get the homepage of mobiletoast.com The strange thing is, I see the expected page (It works), when I open the site from my mobile phone. But when I open the site from my PC (any browser, without any cache, hard refresh), I get the homepage of mobiletoast.com The Linode support team says, they see the correct "It works" page. But I am not able to see that page. This is the output of the command apache2ctl -S root@li339-83:~# apache2ctl -S VirtualHost configuration: wildcard NameVirtualHosts and _default_ servers: *:80 is a NameVirtualHost default server mobiletoast.com (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost mobiletoast.com (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost blog.mobiletoast.com (/etc/apache2/sites-enabled/blog.mobiletoast.com:1) port 80 namevhost lesseltechnologies.com (/etc/apache2/sites-enabled/lesseltechnologies.com:1) port 80 namevhost mobiletoast.com (/etc/apache2/sites-enabled/mobiletoast.com:1) Syntax OK

  • Javascript "Match" Function Not Returning Proper Results in Safari or IE (but yes in FF)

    - by Jascha
    Forgive me as this is a time sensitive issue and I will have to switch the site back in a few hours so the link will be bad... but: I am simply comparing two strings looking for a match with this function... I have an array of objects called linkArray and I need to match the .src of each object to a .src I send it (the src of the clicked image). if the the src of the image I clicked matches the src of an object in my array, I set a variable to the link string of that object and return true, letting my page know that the link is available. Now, this works great in FF. But not in any other browser and I can't figure out for the life of me why. I have set up a dialogue box to literally compare, by eye, the two strings that should at the very least throw the message "match". Can anyone see what I am missing here??? here is the link... http://7thart.com/Jewish-History-and-Culture/Jews-and-Baseball-An-American-Love-Story If you click any of the thumbnails on the left, you will activate the function. Again, I apologize as after a few hours I have to switch back to the original site and this link will be invalid. Thanks in advance for your help. (function below)... function matchLink(a){ for(var i=0;i<linkArray.length;i++){ var fixLink = '../' + linkArray[i]['src']; alert(fixLink + '\n = \n' + a); if(fixLink == a){ alert('match'); newLink = linkArray[i]['link']; return true; } } return false; } Note: The "match" will return on two of the images.. the initial image, and the first thumbnail on the left. The second thumbnail SHOULD match, and the third one SHOULD NOT match.

  • How do I add mouseClicked event to a swing table?

    - by Ayelet
    Hi, I am a new, terribly green user of Swing. I managed to create a table class using examples from java.sun tutorials, and I managed to load data dynamically into it. I want to be able to react to a click on a row by displaying a dialog box. How do I add the event Handler that will identify the selected row number? The main function code: public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { try { MainWindow window = new MainWindow(); window.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Create and set up the content pane. createAndShowGUI(); //... and: private static void createAndShowGUI() { //Create and set up the window. JFrame frame = new JFrame("Data Table"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Create and set up data of the content pane. TableClass mainTable = new TableClass(fh.getColNames(), fh.getTableContent()); mainTable.setOpaque(true); frame.setContentPane(mainTable); //Display the window. frame.pack(); frame.setVisible(true); } Thank you

  • NSSegmentedControl -selectedSegment always returns 0

    - by SphereCat1
    I have an NSSegmentedControl with two segments set to "Select None" mode in Interface Builder. No matter what I try, I can't get -selectedSegment to return anything but 0, even though segment 0 is even disabled by default and can't possibly be selected. Here's the relevant function that gets called when you click any segment on the control: -(IBAction)changeStep:(id)sender { [stepContainer setHidden:TRUE]; [(NSView *)[[wizard stepArray] objectAtIndex:(NSInteger)[wizard step]] removeFromSuperview]; switch ([[navigationButton cell] selectedSegment]) { case 0: [wizard setStep:(NSInteger *)[wizard step]-1]; break; case 1: [wizard setStep:(NSInteger *)[wizard step]+1]; break; default: break; } //[[navigationButton cell] setSelected:FALSE forSegment:[navigationButton selectedSegment]]; if ([wizard step] > 0) { [wizard setStep:0]; [navigationButton setEnabled:FALSE forSegment:0]; } NSLog(@"%d", [wizard step]); [stepContainer addSubview:(NSView *)[[wizard stepArray] objectAtIndex:(NSInteger)[wizard step]]]; [stepContainer setHidden:FALSE withFade:TRUE]; } I've also tried using -isSelectedForSegment, but it has the same result. Any help you can provide would be awesome, I have no idea what I'm doing wrong. Thanks! SphereCat1

  • [C++][Boost] Acceptor and Problems with Async_Accept

    - by bobber205
    See code. :P I am able to receive new connections before async_accept() has been called. My delegate function is also never called so I can't manage any connections I receive, rendering the new connections useless. ;) So here's my question. Is there a way to prevent the Boost ASIO acceptor from getting new connections on its own and only getting connections from async_accept()? Thanks! bool AlexSocket::StartListening(int port) { bool didStart = false; if (!this->listening) { //try to listen acceptor = new tcp::acceptor(this->myService); boost::asio::ip::tcp::endpoint endpoint(boost::asio::ip::tcp::v4(), port); acceptor->open(endpoint.protocol()); acceptor->set_option(boost::asio::ip::tcp::acceptor::reuse_address(true)); acceptor->bind(endpoint); //CAN GET NEW CONNECTIONS HERE (before async_accept is called) acceptor->listen(); didStart = true; //probably change? tcp::socket* tempNewSocket = new tcp::socket(this->myService); acceptor->async_accept(*tempNewSocket, boost::bind(&AlexSocket::NewConnection, this, tempNewSocket, boost::asio::placeholders::error) ); } else //already started! return false; this->listening = didStart; return didStart; } //this function is never called :( void AlexSocket::NewConnection(tcp::socket* s, const boost::system::error_code& error) { cout << "New Connection Made" << endl; //Start new accept async tcp::socket* tempNewSocket = new tcp::socket(this->myService); acceptor->async_accept(*tempNewSocket, boost::bind(&AlexSocket::NewConnection, this, tempNewSocket, boost::asio::placeholders::error) ); }

  • JavaFX MouseEvent continues when I remove the object it happened on

    - by Kyle
    It took me a while to realize what was going on with mouse events going through my blocking dialog boxes when I closed them, but I finally figured out why. I still don't know any good way to fix it. I have a custom dialog box (that blocks the mouse) with a close button. When I click the close button, I remove the dialog box from the scene, but JavaFx is still processing the MouseEvent and now it finds that there is nothing blocking the screen behind where the cancel button was, so that component receives a MouseEvent. How do I make the mouseEvent stop processing when I see that they pressed cancel and remove the dialog box? Or, is there a way to make the removing of the dialog box not happen until after it is done processing the MouseEvent? Example Code for the problem: import javafx.stage.Stage; import javafx.scene.Scene; import javafx.scene.shape.Rectangle; import javafx.scene.input.MouseEvent; import javafx.scene.control.Button; var theScene:Scene; var btn:Button; Stage { title: "Application title" scene: theScene= Scene { width: 500 height: 200 content: [ Rectangle{ width: bind theScene.width height: bind theScene.height onMouseClicked: function(e:MouseEvent):Void{ println("Rectangle");} }, Button{ layoutX: 20 layoutY: 50 blocksMouse: true text: "JustPrint" action:function():Void{ println("JustPrint");} }, btn = Button{ layoutX: 20 layoutY: 20 blocksMouse: true text: "Cancel" action:function():Void{ println("Cancel"); delete btn from theScene.content;} }, ] } } When you press "JustPrint" you get: JustPrint When you press "Cancel" you get: Cancel Rectangle

  • How do I create an inheritable Semaphore in .NET?

    - by pauldoo
    I am trying to create a Win32 Semaphore object which is inheritable. This means that any child processes I launch may automatically have the right to act on the same Win32 object. My code currently looks as follows: Semaphore semaphore = new Semaphore(0, 10); Process process = Process.Start(pathToExecutable, arguments); But the semaphore object in this code cannot be used by the child process. The code I am writing is a port of come working C++. The old C++ code achieves this by the following: SECURITY_ATTRIBUTES security = {0}; security.nLength = sizeof(security); security.bInheritHandle = TRUE; HANDLE semaphore = CreateSemaphore(&security, 0, LONG_MAX, NULL); Then later when CreateProcess is called the bInheritHandles argument is set to TRUE. (In both the C# and C++ case I am using the same child process (which is C++). It takes the semaphore ID on command line, and uses the value directly in a call to ReleaseSemaphore.) I suspect I need to construct a special SemaphoreSecurity or ProcessStartInfo object, but I haven't figured it out yet.

  • How to determine the width of content or size a container to content

    - by ISVK
    My goal is to display the entire contents of a FlowDocument (that is, without paginating) in a column layout. It would have a fixed height, but the width would depend on the contents of the FlowDocument. My problem is: FlowDocumentReader does not automatically resize to the contents of the FlowDocument. As you see in my XAML below, FlowDocumentReader.Width is 5000 units (just a large number that can accommodate most documents) -- when I make it Auto, it just clips to the width of the ScrollViewer and paginates my stuff! Is there a proper way of solving this problem? I also made a screenshot of what this looks like now, but the ScrollViewer scrolls past the end of the document in most cases: http://i.imgur.com/3FSRl.png <ScrollViewer x:Name="scrollViewer" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Disabled" > <FlowDocumentReader x:Name="flowDocReader" ClipToBounds="False" Width="5000" > <FlowDocument x:Name="flowDoc" Foreground="#FF404040" ColumnRuleWidth="2" ColumnGap="40" ColumnRuleBrush="#FF404040" IsHyphenationEnabled="True" IsOptimalParagraphEnabled="True" ColumnWidth="150"> <Paragraph> Lorem ipsum dolor sit amet, ...etc... </Paragraph> <Paragraph> Lorem ipsum dolor sit amet, ...etc... </Paragraph> <Paragraph> Lorem ipsum dolor sit amet, ...etc... </Paragraph> </FlowDocument> </FlowDocumentReader> </ScrollViewer>

  • Layout resize animation

    - by Marcin Sosna
    I have layout: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <LinearLayout android:id="@+id/main_fragment_container" android:layout_width="fill_parent" android:layout_height="fill_parent"> <RelativeLayout android:id="@+id/left_fragments_layout" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="1" android:background="#00F"> </RelativeLayout> <RelativeLayout android:id="@+id/graph_fragment_container" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="2.2" android:background="#666"> </RelativeLayout> <RelativeLayout android:id="@+id/right_fragments_layout" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="1" android:background="#00F"> </RelativeLayout> When I set visibility to GONE on left and right fragment container then they are animated to left and right. I try to set scale animation on resize center graph_fragment_container, my code: <scale android:fromXScale="100%" android:toXScale="50%" android:fillAfter="true" android:fillEnabled="true" android:duration="7000" /> Java code: Animation toLeftOut = AnimationUtils.loadAnimation( MainActivity.this, R.anim.to_left_out ); Animation toRightOut = AnimationUtils.loadAnimation( MainActivity.this, R.anim.to_right_out ); Animation scale = AnimationUtils.loadAnimation( MainActivity.this, R.anim.scal ); graphContainer.startAnimation( scale ); leftFragmentsLayout.startAnimation( toLeftOut ); rightFragmentsLayout.startAnimation( toRightOut ); Now graphContainer was resize after right and left layout animation end, and user see a grey backgound before center layout was resize.
