  • jQuery Tablesorter - disabled headers show progress bar, sortEnd never triggered

    - by McGirl
    I'm combining Tablesorter's 'disable headers using options' function and the 'trigger sortStart / sortEnd' function and have run into an issue. The following code works fine for the most part, BUT: when you click on a disabled header, the progress-indicating #overlay div appears and never goes away. <script type="text/javascript" id="js"> $(document).ready(function() { // call the tablesorter plugin, the magic happens in the markup $("#projectTable").tablesorter({ // pass the headers argument and assing a object headers: { // assign the secound column (we start counting zero) 1: { // disable it by setting the property sorter to false sorter: false }, // assign the third column (we start counting zero) 2: { // disable it by setting the property sorter to false sorter: false } } }); //assign the sortStart event $("#projectTable").bind("sortStart",function() { $("#overlay").show(); }).bind("sortEnd",function() { $("#overlay").hide(); }); }); </script> Any ideas on how I could fix this so that nothing at all happens when the disabled headers are clicked? Thanks!

  • How can I measure TForm deserialization time in Delphi?

    - by mjustin
    For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": before the beginning of the deserialization process after the completion of deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.

  • Will PHP Die In Web Page Development World?

    - by Morgan Cheng
    I know that PHP is still the most popular web programming language in the world. This question just want to bring some of my concerns about PHP. PHP is naturally bound to C10K problem. Since PHP (generally run in Apache) cannot be event-driven or asynchronous, each HTTP request will occupy at least one thread or process. This makes it resistant to be more scalable. Currently, a lot of web sites (like Facebook) with high performance and scalability still depends on PHP in their front end servers. I suppose it is due to legacy reason. Is it possible that PHP will be replaced by language more suitable for C10K?

  • Threads to make video out of images

    - by masood
    updates: I think/ suspect the imageIO is not thread safe. shared by all threads. the read() call might use resources that are also shared. Thus it will give the performance of a single thread no matter how many threads used. ? if its correct . what is the solution (in practical code) Single request and response model at one time do not utilizes full network/internet bandwidth, thus resulting in low performance. (benchmark is of half speed utilization or even lower) This is to make a video out of an IP cam that gives a new image on each request. http://149.5.43.10:8001/snapshot.jpg It makes a delay of 3 - 8 seconds no matter what I do. Changed thread no. and thread time intervals, debugged the code by System.out.println statements to see if threads work. All seems normal. Any help? Please show some practical code. You may modify mine. This code works (javascript) with much smoother frame rate and max bandwidth usage. but the later code (java) dont. same 3 to 8 seconds gap. <!DOCTYPE html> <html> <head> <script type="text/javascript"> (function(){ var img="/*url*/"; var interval=50; var pointer=0; function showImg(image,idx) { if(idx<=pointer) return; document.body.replaceChild(image,document.getElementsByTagName("img")[0]); pointer=idx; preload(); } function preload() { var cache=null,idx=0;; for(var i=0;i<5;i++) { idx=Date.now()+interval*(i+1); cache=new Image(); cache.onload=(function(ele,idx){return function(){showImg(ele,idx);};})(cache,idx); cache.src=img+"?"+idx; } } window.onload=function(){ document.getElementsByTagName("img")[0].onload=preload; document.getElementsByTagName("img")[0].src="/*initial url*/"; }; })(); </script> </head> <body> <img /> </body> </html> and of java (with problem) : package camba; import java.applet.Applet; import java.awt.Button; import java.awt.Graphics; import java.awt.Image; import java.awt.Label; import java.awt.Panel; import java.awt.TextField; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.net.URL; import java.security.Timestamp; import java.util.Date; import java.util.concurrent.TimeUnit; import java.util.concurrent.atomic.AtomicBoolean; import javax.imageio.ImageIO; public class Camba extends Applet implements ActionListener{ Image img; TextField textField; Label label; Button start,stop; boolean terminate = false; long viewTime; public void init(){ label = new Label("please enter camera URL "); add(label); textField = new TextField(30); add(textField); start = new Button("Start"); add(start); start.addActionListener(this); stop = new Button("Stop"); add(stop); stop.addActionListener(this); } public void actionPerformed(ActionEvent e){ Button source = (Button)e.getSource(); if(source.getLabel() == "Start"){ for (int i = 0; i < 7; i++) { myThread(50*i); } System.out.println("start..."); } if(source.getLabel() == "Stop"){ terminate = true; System.out.println("stop..."); } } public void paint(Graphics g) { update(g); } public void update(Graphics g){ try{ viewTime = System.currentTimeMillis(); g.drawImage(img, 100, 100, this); } catch(Exception e) { e.printStackTrace(); } } public void myThread(final int sleepTime){ new Thread(new Runnable() { public void run() { while(!terminate){ try { TimeUnit.MILLISECONDS.sleep(sleepTime); } catch (InterruptedException ex) { ex.printStackTrace(); } long requestTime= 0; Image tempImage = null; try { URL pic = null; requestTime= System.currentTimeMillis(); pic = new URL(getDocumentBase(), textField.getText()); tempImage = ImageIO.read(pic); } catch(Exception e) { e.printStackTrace(); } if(requestTime >= /*last view time*/viewTime){ img = tempImage; Camba.this.repaint(); } } }}).start(); System.out.println("thread started..."); } }

  • Error occure while validating form input using JQUERY in Firebug

    - by Param-Ganak
    Hello Friends, I have written a custom validation code in JQUERY. which is working fine. I have a login form which have two fields i.e. userid and password. I have written a custom JQUERY code for client side validation for these fields. This custom JQUERY code is working fine and gives me proper error messages as per the situation. But the problem with this code is that when I enter the invalid data in any or both field and press submit button of form then it displays the proper error message but at the same time when I checked it in Firebug it displays following error message when submit button of the form is clicked validate is not defined function onclick(event) { javascript: return validate(); }(click clientX=473, clientY=273) So please tell me where is I am wrong in my Jquery code. Thank You!

  • How to implement async pattern in windows forms application?

    - by Alkersan
    I'm using an MVC pattern in winforms application. I need to call remote service asynchronously. So On some event in View I invoke corresponding Presenter method. In Presenter I call BeginInvoke method of service. But to View must be updated only in Main Thread. I could actualy point CallBack to some function in View, and update it`s controls state, but this conflicts with MVP pattern - View must not be responsible for data it carries. This callback function must be in Presenter. But how then invoke View in Main Thread?

  • How can I prevent a ToggleButton from being Toggled without setting IsEnabled=False

    - by Bryan Anderson
    I have a list of ToggleButtons being used as the ItemTemplate in a ListBox similar to this answer using the MultiSelect mode of the Listbox. However I need to make sure at least one item is always selected. I can get the proper behavior from the ListBox by just adding an item back into the ListBox's SelectedItems collection on the ListBox.SelectionChanged event but my ToggleButton still moves out of its toggled state so I think I need to stop it earlier in the process. I would like to do it without setting IsEnabled="False" on the last button Selected because I'd prefer to stay with the Enabled visual style without having to redo my button templates. Any ideas?

  • How do you set page level, page-SPECIFIC javascript events using a ContentPlaceHolder?

    - by donde
    I previously asked how to include Javascript in my page when I split the page into a MasterPage and ContentPlaceHolder (.NET 2.0 app) The issue was I only wanted the javascript functions on THAT page so I couldn't just put them on the masterpage. Based on the answers, I will inlcude common fucntions through MasterPage and can put the page-specific function right on the content page. However, 1 question remains: Events. I have 2 Javascript functions that I wanted to load when the page loads ala the HTML below. How do you load javascript page events on the specific content page? Or in the case below, the OnKeyPress event? <body onkeypress="javascript:keypressed();" onload="javascript:setDivVisibility();">

  • Modifying a global variable from <a href>

    - by a_m0d
    I have created some code to popup a confirm dialog if a user tries to leave a page without saving their changes. However, I don't want the confirmation dialog to popup if the user has clicked the "Save" button. I have some code at the top of my file which looks like this: var confirmClose = false; window.onbeforeunload = function(evt) { if (confirmClose == true) { message = "There are unsaved changes on this page. Are you sure you wish to leave?"; if (typeof evt == 'undefined') { evt = window.event; } if (evt) { evt.returnValue = message; } return message; } } Further down on the page I have a link which looks like this: <a href="javascript:confirmClose=false;$('#stockForm').submit()" title="Save" class="button positive" id="stockFormSubmit">Save</a> However, this doesn't seem to work - it doesn't seem to change the value of confirmClose, and changing it to window.confirmClose didn't help either. What am I doing wrong here?

  • How can I navigate through xaml pages with Monogame in a Windows Phone 8 project?

    - by misiMe
    I finished to develop an XNA game, then I created the Monogame project, and tested it on my device. Now I made some other pages such as an "about" page. How can I go to that page considering I have a Monogame project and just an XNA code? In particular inside my game I made a Main Menu where you can click the "about" button and know if someone has clicked: how can I link that event to the "go to about.xaml" function? Inside XNA, update method: if (about_button.IsClicked()) { // Go to about.xaml } I tried: if (about_button.IsClicked()) { ((PhoneApplicationFrame)Application.Current.RootVisual).Navigate(new Uri("/About.xaml", UriKind.Relative)); } But it throws: System.UnauthorizedAccessException

  • How to create a glib.Source from Python?

    - by Matt Joiner
    I want to integrate some asyncore.dispatcher instances into GLib's default main context. I figure I can create a custom GSource that's able to detect event readiness on the various sockets in asyncore.socket_map. From C I believe this is done by creating the necessary GSourceFuncs which could involve cheap and non-blocking calls to select, and then handling them using asyncore.read, .write and friends. How do I actually create a GSource from Python? The class glib.Source is undocumented, and attempts to use the class interactively have been in vain. Is there some other method that allows me to handled socket events in the asyncore module without resorting to timeouts (or anything that endangers potential throughput and CPU usage)?

  • Events doesn't fire when using UpdatePanel

    - by nitinkhanna
    Hi, What I did is, I have made 2 user controls. One control is inside the other. NoW one control has a buttton and a data grid and datalist in it. When pressing button I am filling datagrid while datalist visiblity false. This is working fine. But now when I press some link button in datalist data, it should call item_command event but it is not calling. I have also used a Updatepanel as a wrapper(all controls are inside it). Please suggest what may be the reason for that. Thanks

  • mysql_close doesn't kill locked sql requests

    - by Nikita
    I use mysqld Ver 5.1.37-2-log for debian-linux-gnu I perform mysql calls from c++ code with functions mysql_query. The problem occurs when mysql_query execute procedure, procedure locked on locked table, so mysql_query hangs. If send kill signal to application then we can see lock until table is locked. Create the following SQL table and procedure CREATE TABLE IF NOT EXISTS `tabletolock` ( `id` INT NOT NULL AUTO_INCREMENT, PRIMARY KEY (`id`) )ENGINE = InnoDB; DELIMITER $$ DROP PROCEDURE IF EXISTS `LOCK_PROCEDURE` $$ CREATE PROCEDURE `LOCK_PROCEDURE`() BEGIN SELECT id INTO @id FROM tabletolock; END $$ DELOMITER; There are sql commands to reproduce the problem: 1. in one terminal execute lock tables tabletolock write; 2. in another terminal execute call LOCK_PROCEDURE(); 3. In first terminal exeute show processlist and see | 2492 | root | localhost | syn_db | Query | 12 | Locked | SELECT id INTO @id FROM tabletolock | Then perfrom Ctrl-C in second terminal to interrupt our procudere and see processlist again. It is not changed, we already see locked select request and can teminate it by unlock tables or kill commands. Problem described is occured with mysql command line client. Also such problem exists when we use functions mysql_query and mysql_close. Example of c code: #include <iostream> #include <mysql/mysql.h> #include <mysql/errmsg.h> #include <signal.h> // g++ -Wall -g -fPIC -lmysqlclient dbtest.cpp using namespace std; MYSQL * connection = NULL; void closeconnection() { if(connection != NULL) { cout << "close connection !\n"; mysql_close(connection); mysql_thread_end(); delete connection; mysql_library_end(); } } void sigkill(int s) { closeconnection(); signal(SIGINT, NULL); raise(s); } int main(int argc, char ** argv) { signal(SIGINT, sigkill); connection = new MYSQL; mysql_init(connection); mysql_options(connection, MYSQL_READ_DEFAULT_GROUP, "nnfc"); if (!mysql_real_connect(connection, "127.0.0.1", "user", "password", "db", 3306, NULL, CLIENT_MULTI_RESULTS)) { delete connection; cout << "cannot connect\n"; return -1; } cout << "before procedure call\n"; mysql_query(connection, "CALL LOCK_PROCEDURE();"); cout << "after procedure call\n"; closeconnection(); return 0; } Compile it, and perform the folloing actions: 1. in first terminal local tables tabletolock write; 2. run program ./a.out 3. interrupt program Ctrl-C. on the screen we see that closeconnection function is called, so connection is closed. 4. in first terminal execute show processlist and see that procedure was not intrrupted. My question is how to terminate such locked calls from c code? Thank you in advance!

  • Send post data while opening SSE connection

    - by Prosto Trader
    I'm trying to establish SSE connection and do some long-taking actions on server-side, informing user about how it goes through SSE events. Actually, I don't understand how would I send some data along with new connection. I have to combine regular ajax with new EventSource or there is a way to transfer post data inside that event? Here is what I have so far, and I need to send pretty big JSON with the request. Is it possible or the only way to send data is GET? var source = new EventSource('/terminal/ajax-put-packet-trade-order/');

  • touchesMoved QuartzDemo application

    - by BittenApple
    I am modifying the QuartzDemo application to include swipe detection while UIView is active (a PDF page being displayed in it via Quartz). This will not work, the event never gets to the QuartzView.m because it sits under scrollview? touchesBegan works fine and I can use single tap. How can I go about with catching touchesMoved while PDF page is being displayed? I need a simple example with code that does nothing on touchesMoved, I'll build up on that later. Please keep in mind that I still want to use the UIScrollview as it is and show PDF content based on selection in that scrollview.

  • Cannot add an entity that already exists. (LINQ to SQL)

    Hello guys, in my database there are 3 tables CustomerType CusID EventType EventTypeID CustomerEventType CusID EventTypeID Dim db = new CustomerEventDataContext Dim newEvent = new EventType newEvent.EventTypeID = txtEventID.text db.EventType.InsertOnSubmit(newEvent) db.SubmitChanges() 'To select the last ID of event' Dim lastEventID = (from e in db.EventType Select e.EventTypeID Order By EventTypeID Descending).first() Dim chkbx As CheckBoxList = CType(form1.FindControl("CheckBoxList1"), CheckBoxList) Dim newCustomerEventType = New CustomerEventType Dim i As Integer For i = 0 To chkbx.Items.Count - 1 Step i + 1 If (chkbx.Items(i).Selected) Then newCustomerEventType.INTEVENTTYPEID = lastEventID newCustomerEventType.INTSTUDENTTYPEID = chkbxStudentType.Items(i).Value db.CustomerEventType.InsertOnSubmit(newCustomerEventType) db.SubmitChanges() End If Next It works fine when I checked only 1 Single ID of CustomerEventType from CheckBoxList1. It inserts data into EventType with ID 1 and CustomerEventType ID 1. However, when I checked both of them, the error message said Cannot add an entity that already exists. Any suggestions please? Thx in advance.

  • Best way to do syntax highlighting in GTK+?

    - by Tyler
    I was wondering if someone could point me to an example of (or just their thoughts on) the best way to code syntax highlighting in a C-based GTK+ application. I know that I can use the GtkTextTag to modify text in a GtkTextBuffer but beyond searching out keywords (iteratively or by regexing the string) is there a better way? My only concern is that if I wipe all of the tags and then re-search and apply the tags at every text change event it could really bog down my application. As always thanks for your help!

  • RadioGroup getValue does not return correct slected value

    - by vagabond
    I'm running into a small issue with RadioGroup. My RadioGroup has possible values, true and false. The Radio types I have in my radiogroup use a Model that stores true or false. On an ajax onchange event I want to do some handling, and to do so I need to know the selected radio in my radiogroup and another identical radiogroup. The problem is getValue() only returns the initial value from my Pojo. Whenver I click on a radio button to change the selected Radio getValue() still returns the initial value. When I save my changes, my Pojo gets the correct value. I am finding this bizarre and have spent hours trying to figure our what I'm missing.

  • [Cocoa] NSImage transparency

    - by ndg
    I'm trying to set a custom drag icon for use in an NSTableView. Everything seems to work but I've run into a problem due to my inexperience with Quartz. - (NSImage *)dragImageForRowsWithIndexes:(NSIndexSet *)dragRows tableColumns:(NSArray *)tableColumns event:(NSEvent *)dragEvent offset:(NSPointPointer)dragImageOffset { NSImage *dragImage = [NSImage imageNamed:@"icon.png"]; NSString *count = [NSString stringWithFormat:@"%d", [dragRows count]]; [dragImage lockFocus]; [dragImage compositeToPoint:NSZeroPoint fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:0.5]; [count drawAtPoint:NSZeroPoint withAttributes:nil]; [dragImage unlockFocus]; return dragImage; } Essentially what I'm looking to do is render my icon.png file with 50% opacity along with an NSString which shows the number of rows currently being dragged. The issue I'm seeing is that my NSString renders with a low opacity, but not my icon.

  • C# Custom Control Properties load before Load and arrays are empties

    - by Wildhorn
    Hello, I made a custom control with custom properties. When I modify these properties in the "Form.cs [Design]", I need stuff to happens (it fill some arrays and modify the look of the control), so I call a function within the "set" of the property. All of this works good. My problem is that when I run the program with my custom control, it seems that properties "set" is called, which will call the function, but then, my arrays seems now to have lost all their values and the function use these arrays, but now because they are all empty, it crashes due to NullException blahblahblah. It also seems that properties "set" is called before the control Load (which I guess is called only when it is added to my Form, and not when the Form load). So question is, why does my arrays become empty once I try to run the Form and is there an event that is called before that when the Form load? Thanks

  • Listening to another window resize events in C#

    - by Steve
    Hi all I am implementing a small application (observer) that needs to "attach" itself to the bottom of another window (observed). The latter is not a window inside the application. At this moment I solved by getting the hWnd of the window and querying periodically in a thread the location of the observed window, moving the observer window accordingly. However this is a very inelegant solution. What I would like to do is to listen to the resize event of the observed window so that the observer will react only when necessary. I assume I should use a hook, and I found plenty of ways of doing it, but my lack of knowledge of the C WinAPI is blocking me in understanding which hook I need to create and how (pinvoke/parameters/etc). I'm pretty sure this is quite trivial, and some of you familiar with C/C++ and WinAPI will have the answer ready at hand ;) Thanks
