  • Temporarily disable vim plugin without relaunching

    - by simont
    I'm using c-support in Vim. One of it's features is the automatic comment expansion. When I'm pasting code into Vim from an external editor, the comments are expanded (which gives me double-comments and messes up the paste - see below for example). I'd like to be able to disable the plugin, paste, then re-enable it, without relaunching Vim. I'm not sure if this is possible. The SO questions here, here and here all describe methods to disable plugins, but they all require me to close Vim, mess with my .vimrc or similar, and relaunch; if I have to close Vim, I might as well cat file1 >> myfile; vim myfile, then shift the lines internally, which will be just as quick. Is it possible to disable a plugin while running vim without relaunching, preferably in a way which allows me to map a hot-key toggle-plugin (so re-sourcing ~/.vimrc is alright; that's mappable to a hotkey [I imagine, haven't tried it yet])? Messed up comments: /* * * Authors: * * A Name * * * * Copyright: * * A Name, 2012 * */ EDIT: It turns out you can :set paste, :set nopaste (which, to quote :help paste, will "avoid unexpected effects [while pasting]". (See the comments). However, I'm still curious whether you can disable/enable a plugin as per the original question, so I shall leave the question open.

  • Clicking mouse by sending messages

    - by Frank Meulenaar
    I'm trying to send mouse clicks to a program. As I don't want the mouse to move, I don't want to use SendInput or mouse_event, and because the window that should receive the clicks doesn't really use Buttons or other GUI events, I can't send messages to these buttons. I'm trying to get this working using SendMessage, but for some reason it doesn't work. Relevant code is (in C#, but tried Java with jnative as well), trying this on Vista [DllImport("user32.dll", CharSet=CharSet.Auto)] public static extern int SendMessage(IntPtr A_0, int A_1, int A_2, int A_3); static int WM_CLOSE = 0x10; static int WM_LBUTTONDOWN = 0x201; static int WM_LBUTTONUP = 0x202; public static void click(IntPtr hWnd, int x, int y) { SendMessage(hWnd, WM_LBUTTONDOWN, 1, ((x << 0x10) ^ y)); SendMessage(hWnd, WM_LBUTTONUP, 0, ((x << 0x10) ^ y)); } public static void close(IntPtr hWnd) { SendMessage(hWnd, WM_CLOSE, 0, 0); } The close works fine, but the click doesn't do anything.

  • PHP: How to know if a user is currently downloading a file?

    - by metrobalderas
    I'm developing a quick rapidshare-like site where the user can download files. First, I created a quick test setting headers and using readfile() but then I found in the comments section there's a way to limit the speed of the download, which is great, here's the code: $local_file = 'file.zip'; $download_file = 'name.zip'; // set the download rate limit (=> 20,5 kb/s) $download_rate = 20.5; if(file_exists($local_file) && is_file($local_file)) { header('Cache-control: private'); header('Content-Type: application/octet-stream'); header('Content-Length: '.filesize($local_file)); header('Content-Disposition: filename='.$download_file); flush(); $file = fopen($local_file, "r"); while(!feof($file)) { // send the current file part to the browser print fread($file, round($download_rate * 1024)); // flush the content to the browser flush(); // sleep one second sleep(1); } fclose($file);} else { die('Error: The file '.$local_file.' does not exist!'); } But now my question is, how to limit the number of downloads at the same time? How can I check there's still a connection with some user's IP? Thanks.

  • autoreload webpage on new release

    - by user3726562
    I have a website in PHP which is completely ajax-based. There is an index.php, but a part from it, all the other page are never rendered directly into the browser. Instead, all the post and get request are done tfrom javascript through ajax. So basically, if you go to /contact.php you will not see anything. All the pages are rendered inside index.php. So, there are a lot of people that use this page that are not very good in using the web. Asking them to "refresh" the page makes them to wonder what we are talking about. Unfortunately. The biggest issue happens when we do a new release. Especially the javascript code (but not only) can be the old one in a client's webpage as they maybe havent refreshed the page for some week (lol). S I do an svn-update and the new code is on the server. I just refresh my page and see the new features. However, the poor guys that dont really know how to make a refresh, will not see anything. I have added a big button on the page with the text "refresh". Which makes a location.reload. Hopefully this can help a few of them. But my question is: how to "force" the browser to reload itself when a new svn-version has been released? Hopefully in a simple way, without needing some node.js, javascript timer or stuff like that. It is also quite important to not refresh the page when the user is doing something with the page (maybe writing a mail in the UI, and then suddenly the page get refreshed: not so good).

  • Required attribute HTML5

    - by Joop
    First of all I will explain how I stumbled into this behavior. Within my web application I am using some custom validation for my form fields. Within the same form I have two buttons. One to actually submit the form and the other to cancel/reset the form. Mostly I use Safari as my default browser. Now Safari 5 is out and suddenly my cancel/reset button didn't work anymore. Every time I did hit the reset button the first field in my form did get the focus. However this is the same behavior as my custom form validation. When trying it with another browser everything just worked fine. I had to be a Safari 5 problem. I changed a bit in my Javascript code and I found out that the following line was causing the problem: document.getElementById("somefield").required = true; To be sure that would be really the problem I created a test scenario: <!DOCTYPE html> <html> <head> <title>Test</title> </head> <body> <form id="someform"> <label>Name:</label>&nbsp;<input type="text" id="name" required="true" /><br/> <label>Car:</label>&nbsp;<input type="text" id="car" required="true" /><br/> <br/> <input type="submit" id="btnsubmit" value="Submit!" /> </form> </body> </html> What I expected would happen did happen. The first field "name" did get the focus automatically. Anyone else stumbled into this?

  • How to check dates don't overlap in a table using TSQL.

    - by Jon
    I have a table with start and finish datetimes that I need to determine if any overlap and not quite sure the best way to go. Initially I was thinking of using a nested cursor as shown below which does work, however I'm checking the same records against each other twice and I'm sure it is not very efficient. eg: this table would result in an overlap. id start end ------------------------------------------------------- 1 2009-10-22 10:19:00.000 2009-10-22 11:40:00.000 2 2009-10-22 10:31:00.000 2009-10-22 13:34:00.000 3 2009-10-22 16:31:00.000 2009-10-22 17:34:00.000 Declare @Start datetime, @End datetime, @OtherStart datetime, @OtherEnd datetime, @id int, @endCheck bit Set @endCheck = 0 DECLARE Cur1 CURSOR FOR select id, start, end from table1 OPEN Cur1 FETCH NEXT FROM Cur1 INTO @id, @Start, @End WHILE @@FETCH_STATUS = 0 AND @endCheck = 0 BEGIN -- Get a cursor on all the other records DECLARE Cur2 CURSOR FOR select start, end from table1 and id != @id OPEN Cur2 FETCH NEXT FROM Cur2 INTO @OtherStart, @OtherEnd WHILE @@FETCH_STATUS = 0 AND @endCheck = 0 BEGIN if ( @Start > @OtherStart AND @Start < @OtherEnd OR @End > @OtherStart AND @End < @OtherEnd ) or ( @OtherStart > @Start AND @OtherStart < @End OR @OtherEnd > @Start AND @OtherEnd < @End ) BEGIN SET @endCheck = 1 END FETCH NEXT FROM Cur2 INTO @OtherStart, @OtherEnd END CLOSE Cur2 DEALLOCATE Cur2 FETCH NEXT FROM Cur1 INTO @id, @Start, @End END CLOSE Cur1 DEALLOCATE Cur1

  • PHP Saving information to MySQL but not using hard coded code

    - by Homer_J
    Hi guys, Thanks everyone for assisting me but know I'm well and truely stuck...hopefully someone can advise? My current code that saves to a MySQL database: $q1 = $_POST["q1"]; $q2 = $_POST["q2"]; $q3 = $_POST["q3"]; $q4 = $_POST["q4"]; $q5 = $_POST["q5"]; $q6 = $_POST["q6"]; $q7 = $_POST["q7"]; $q8 = $_POST["q8"]; $proc = mysqli_prepare($link, "INSERT INTO tresults_bh_main (respondent_id, ip, browser, q1, q2, q3, q4, q5, q6, q7, q8) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?);"); mysqli_stmt_bind_param($proc, "issiiiiiiii", $respondent_id, $ip, $browser, $q1, $q2, $q3, $q4, $q5, $q6, $q7, $q8); At the moment this is all hard coded and I need it to use variables: I have an array which stores the following information: $qs['questions'] - stores, for example q1, q2, q3, q4 etc - obviously these change both in terms of of numbers, ie. q10, q11, q12 and also the amount in the array - so there could be 4 q's or 10 q's stored in the array. What I struggling to get my head around is how I would set-up this hard coded page to work with my variables. If anyone can help, much appreciated. Homer.

  • How would I automate my array to be used with cURL?

    - by Rob
    I have an array containing the contents of a MySQL table. I need to put each of these contents into curl_multi_handles so that I can execute them all simultaneously Here is the code for the array, in case it helps: $SQL = mysql_query("SELECT url FROM urls") or die(mysql_error()); while($resultSet = mysql_fetch_array($SQL)){ $urls[]=$resultSet } So I need to put be able to send data to each url at the same time. I don't need to get any data back, and in fact I'll be having them time out after two seconds. It only needs to send the data and then close. My code prior to this, was executing them one at a time. here is that code: $SQL = mysql_query("SELECT url FROM shells") or die(mysql_error()); while($resultSet = mysql_fetch_array($SQL)){ $ch = curl_init($resultSet['url'] . $fullcurl); //load the urls and send GET data curl_setopt($ch, CURLOPT_TIMEOUT, 2); //Only load it for two seconds (Long enough to send the data) curl_exec($ch); curl_close($ch); So my question is: How can I load the contents of the array into curl_multi_handle, execute it, and then remove each handle and close the curl_multi_handle?

  • Passing Javascript value to PHP Variable using ajax

    - by shels
    I am trying to use a Flash detection script to assess whether Flash Plugin is enabled in the user browser so that a different page loads. The Flash detection script is as follows, using jquery 1.8.2 and jquery.jqplugin 1.0.2 <script type="text/javascript" src="jquery-1.8.2.min.js"></script> <script type="text/javascript" src="jquery.jqplugin.1.0.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#withflash").hide(); $("#noflash").hide(); if ($.browser.flash == true) $("#withflash").show (); else $("#noflash").show (); }); </script> <div id="withflash">Flash Supported</div> <div id="noflash">Flash Not Supported</div> I get the display that "Flash Supported" if Flash Plugin is present.. I need to capture the value whether flash plugin value is true in a php variable $hasFlashSupport as below: <?php echo " $hasFlashSupport"; exit; ?> I am aware that PHP is server based and Javascript is client based.. Hence Ajax would be a nice option to capture the javascript variable to my php variable. I am totally ignorant about Ajax syntax and how to achieve it. Request the experts here to help me out with the code on how this can be achieved... Thanking all of you in advance..

  • Why would JSP tags appear in HTML source code?

    - by Michael
    I'm a front-end web developer at a company using Java on their server. As a front-end developer, I'm concerned with the HTML structure that the server produces, but I don't have control over anything our back-end team produces. Rather than ask someone on that team, I would like to gather knowledge from the Stackoverflow community so I can communicate intelligently with the back-end team. So, I am curious as to what would cause certain JSP tags to appear in the rendered HTML that is sent to the browser. We have tags in our HTML source such as: <flow:fileRef id="vfileColor" fileId="vfile.color"/> <flow:fileRef id="StyleDir" fileId="StyleDir"/> <flow:fileRef id="vfileStylesheet" fileId="vfile.stylesheet"/> I am more interested in knowing why these appear, not as much about what they do. Is there a server setting for Tomcat/Apache/etc. that would hide these tags from the browser? Any information would be helpful. Thanks in advance.

  • how to tune BufferedInputStream read()?

    - by technomax
    I am reading a BLOB column from a Oracle database, then writing it to a file as follows: public static int execute(String filename, BLOB blob) { int success = 1; try { File blobFile = new File(filename); FileOutputStream outStream = new FileOutputStream(blobFile); BufferedInputStream inStream = new BufferedInputStream(blob.getBinaryStream()); int length = -1; int size = blob.getBufferSize(); byte[] buffer = new byte[size]; while ((length = inStream.read(buffer)) != -1) { outStream.write(buffer, 0, length); outStream.flush(); } inStream.close(); outStream.close(); } catch (Exception e) { e.printStackTrace(); System.out.println("ERROR(img_exportBlob) Unable to export:"+filename); success = 0; } } The file size is around 3MB and it takes 40-50s to read the buffer. Its actually a 3D image data. So, is there any way by which I can reduce this time?

  • what happens when you stop VS debugger?

    - by mare
    If I have a line like this ContentRepository.Update(existing); that goes into datastore repository to update some object and I have a try..catch block in this Update function like this: string file = XmlProvider.DataStorePhysicalPath + o.GetType().Name + Path.DirectorySeparatorChar + o.Slug + ".xml"; DataContractSerializer dcs = new DataContractSerializer(typeof (BaseContentObject)); using ( XmlDictionaryWriter myWriter = XmlDictionaryWriter.CreateTextWriter(new FileStream(file, FileMode.Truncate, FileAccess.Write), Encoding.UTF8)) { try { dcs.WriteObject(myWriter, o); myWriter.Close(); } catch (Exception) { // if anything goes wrong, delete the created file if (File.Exists(file)) File.Delete(file); if(myWriter.WriteState!=WriteState.Closed) myWriter.Close(); } } then why would Visual Studio go on with calling Update() if I click "Stop" in debugging session on the above line? For instance, I came to that line by going line by line pressing F10 and now I'm on that line which is colored yellow and I press Stop. Apparently what happens is, VS goes to execute the Update() method and somehow figures out something gone wrong and goes into "catch" and deletes the file, which is wrong, because I want my catch to work when there is a true exception not when I debug a program and force to stop it.

  • Rails 4 testing bug?

    - by Jamato
    Situation: if we add two identic line items into a cart, we update line item quantity instead of adding a duplicate.In browser everything works fine but in unit testing section something fails because of an empty cycle in code. Which I wanted to use to update all prices. Why? Is that a unit test engine bug? LineItem.all and cart.line_items in process of testing produce two DIFFERENT structures. #<LineItem id: 980190964, product_id: 1, cart_id: 999, created_at: "2014-06-01 00:21:28", updated_at: "2014-06-01 00:21:28", quantity: 2, price: #<BigDecimal:ba0fb544,'0.4E1',9(27)>> #<LineItem id: 980190964, product_id: 1, cart_id: 999, created_at: "2014-06-01 00:21:28", updated_at: "2014-06-01 00:21:28", quantity: 1, price: #<BigDecimal:ba0d1b04,'0.4E1',9(27)>> cart.line_items guy did not update quantity Code itself (produces LineItem which is then saved in line_item_controller which calls this method) class Cart < ActiveRecord::Base has_many :line_items, dependent: :destroy def add_product(product_id) # LOOK THIS CYCLE BREAKS UNIT TEST, SRSLY, I MEAN IT line_items.each do |item| end current_item = line_items.find_by(product_id: product_id) fresh_price = Product.find_by(id: product_id).price if current_item current_item.quantity += 1 else current_item = line_items.build(product_id: product_id, price: fresh_price) end return current_item end ... Unit test code test "non-unique item added" do cart = Cart.new(:id => 999) line_item0 = cart.add_product(2) line_item0.save line_item1 = cart.add_product(1) line_item1.save assert_equal 2, cart.line_items.size #success line_item2 = cart.add_product(1) line_item2.save assert_equal 2, cart.line_items.size, "what?" assert cart.total_price > 15 #fail, prices are not enough, quantity of product1 = 1 #we get total price from quantity, it's a simple method in model end And once again: IT DOES WORK in browser as it should. Even with cycle. I feel so dumb right now...

  • jQuery Toggle switch images

    - by Sixfoot Studio
    Hi Guys, I have a situation where I am not understanding jQuery's Toggle. I have two buttons, both of them open the same content and when you click on either button the content should open or close and the attribute changes the button from open to closed. (So both buttons do the same function). Only thing is, when I click on the top button and it opens my content and then click on the lower button to close it, the image attributes are switched incorrectly. Here's a very stripped down version of what my code looks like and I would appreciate some help. <script language="javascript" type="text/javascript"> $(function () { var open = false; $("#button1, #button2").toggle( function () { open = true; $("#button1").attr("src", "images/btn-open.gif"); $("#button2").attr("src", "images/btn-open.gif"); }, function () { if (open) { $("#button1").attr("src", "images/btn-closed.gif"); $("#button2").attr("src", "images/btn-closed.gif"); } else { $("#button1").attr("src", "images/btn-open.gif"); $("#button2").attr("src", "images/btn-open.gif"); } open = false; } ); }); </script> <img id="button1" src="images/btn-open.gif"></img> <br /> <br /> <br /> <br /> <img id="button2" src="images/btn-open.gif"></img>

  • How can I write output to a new external file with Perl?

    - by Structure
    Maybe I am searching with the wrong keywords or this is a very basic question but I cannot find the answer to my question. I am having trouble writing the result of my whois command to a new external file. My code is below. It takes $readfilename, which is a file name which has a list of IPs, and $writefilename, which is the destination file for output. Both are user-specified. For my tests, $readfilename contains three IP addresses on three separate lines so there should be three separate whois results in the user specified output file. if ($readfilename) { open (my $inputfile, "<", $readfilename) || die "\n Cannot open the specified file. Please double check your file name and path.\n\n"; open (my $outputfile, ">", $writefilename) || die "\n Could not create write file.\n\n"; while (<$inputfile>) { my $iplookupresult = `whois $_`; print $outputfile $iplookupresult; } close $outputfile; close $inputfile; } I can execute this script and end up with a new external file, but over half of the file has binary garbage data (running on CentOS) and only one (or a portion of one) of the whois lookups is readable. I have no idea how half of my file is ending up binary... but my approach must be incorrect. Is there a better way to achieve the same result?

  • VB Change Calulator

    - by BlueBeast
    I am creating a VB 2008 change calculator as an assignment. The program is to use the amount paid - the amount due to calculate the total.(this is working fine). After that, it is to break that amount down into dollars, quarters, dimes, nickels, and pennies. The problem I am having is that sometimes the quantity of pennies, nickels or dimes will be a negative number. For example $2.99 = 3 Dollars and -1 Pennies.

    The same way DOS morphed into Windows? We seem to have ended up supporting and developing for three platforms from Microsoft, and I'm not sure where the boundaries are supposed to lie. Why can't the benefits of the CLR (such as type safety, memory protection, etc.) be built into Windows itself? Or into the browser? Why an entirely other virtual machine? (How may levels of virtual machine indirection are we dealing with now? We just added Silverlight - and before that Flash - running inside the Browser running inside maybe a VM install...) I can see raw Windows for servers, but why couldn't there be a CLR for workstations talking directly to the hardware (or at least not the whole Windows legacy ball and chain)? (ooppp - I've got two questions here. Let's make this - why can't .net be built into Windows? I understand about backward compatibility - but the safety of what's in .NET could be at least optionally in Windows itself, couldn't it? It would just be yet another of many sets of APIs?) Factoid - I recall that one of the competitor architectures selling against MS-DOS on the IBM PC was UCSD-pascal runtime - a VM.

  • How to make sure an action completes before you continue

    - by HurkNburkS
    I am trying to close a UIView thats in one method from another method by calling it, The UIView closes fine but not untill after all of the processes are finished in the current method. I would like to know if there is a way to force the first thing to happen first (i.e. close UIviews) then continue the current method? This is what my method looks like - (void)selectDeselectAllPressed:(UIButton*)button { int id = button.tag; [SVProgressHUD showWithStatus:@"Updating" maskType:SVProgressHUDMaskTypeGradient]; [self displaySelected]; // removes current view so you can load hud will not be behind it if (id == 1) { [self selectAllD]; } else if (id == 2) { [self deselectAllD]; } else if (id == 3) { [self selectAllI]; } else if (id == 4) { [self deselectAllI]; } } as you can see what happens is this method is called when a button is pressed, I would like for the displaySelected method to do what it needs to do before any of the other methods are called? Currently what happes when i debug this is displaySelected method is called the thread walks through that then continues to the if statment then after the method in the if statment has finished then displaySelected changes are made... its so weird. any help would be greatly appreciated.

  • PHP function to handle most database queries has a problem with results. I am getting the right numb

    - by asdasds
    Here is my little function. It does not handle the results correctly. I do get all the rows that I want, but all the rows of the $results array contain the exact same values. So i make 2 arrays, a temporary array to hold the values after each fetch, and another array to hold all the temporary arrays. First i take the temp array and map its keys to the column names. Then i give it to bind_result, and call fetch() and use it like I would any other result value. Could this be because I re-use the $results array? numresults is the number of values you are taking from each row. if 0, you are not getting any results back. function db_query($db, $query, $params = NULL, $numresults = 0) { if($stmt = $db -> prepare($query)) { if($params != NULL) { call_user_func_array(array($stmt, 'bind_param'), $params); } if(!$stmt -> execute()) { //echo 'exec error:',$db->error; return false; } if($numresults > 0) { $results = array(); $tmpresult = array(); $meta = $stmt->result_metadata(); while ($columnName = $meta->fetch_field()) $tmpresult[] = &$results[$columnName->name]; call_user_func_array(array($stmt, 'bind_result'), $tmpresult); $meta->close(); $results = array(); while($stmt -> fetch()) $results[] = $tmpresult; } $stmt -> close(); } else { //echo 'prepare error: ',$db->error; return false; } if($numresults == 0) return true; return $results; }
