  • Jquery, how to escape quotes

    - by Sandro Antonucci
    I'm using a simple jquery code that grabs html code form a tag and then puts this content into a form input <td class="name_cat" ><span class="name_cat">It&#039;s a &quot;test&quot; </span> (5)</td> jquery gets the content into span.name_catand returns it as It's a "test". So when I print this into an input it becomes <input value="It's a "test"" /> which as you can imagine will only show as It's a , the following double quote will close the value tag. What's the trick here to keep the original string while not showing utf8 code in the input? Jquery code $(".edit_cat").click(function(){ tr = $(this).parents("tr:first"); id_cat = $(this).attr("id"); td_name = tr.find(".name_cat"); span_name = tr.find("span.name_cat").html(); form = '<form action="/admin/controllers/edit_cat.php" method="post" >'+ '<input type="hidden" name="id_cat" value="'+id_cat+'" />'+ '<input type="text" name="name_cat" value="'+span_name+'" />'+ '<input type="submit" value="save" />'+ '</form>'; td_name.html(form); console.log(span_name); } ); I basically need html() not to decode Utf8

  • Why is my emit not getting called?

  • sendto is returning ENOBUF

    - by user338159
    Hi, I am currently running an old system on Tru64 which involves lots of UDP sockets using the sendto() function. The sockets are used in our code to send messages to/from various processes and then eventually on to a thick client app that is connected remotely. Occasionally the socket to the thick client gets stuck, this can cause some of these messages to get built up. My question is how can I determine the current buffer size, and how do I determine the maximum message buffer. The code below gives a snippet of how I set up the port and use the sendto function. /* need to adjust the maximum size we can send on this / / as it needs to be able to cope with the biggest / / messages we send / lenlen = sizeof(len) ; / allow double for when the system is under load */ len = 2 * C_MAX_MESSAGE_DATA_SIZE ; lpos_setsockopt(FATAL, msg_socket,SOL_SOCKET, SO_SNDBUF, &len, lenlen, &error_no) ; result = sendto( msg_socket, (char *)message, (int)message_len, flags, dest_addr, addrlen); Note. We have ported this application to Linux and the problem does not seem to appear there. Any help would be greatly appreciated. Regards

  • C# : Regular Expression

    - by Pramodh
    I'm having a set of row data as follows List<String> l_lstRowData = new List<string> { "Data 1 32:01805043*0FFFFFFF", "Data 3, 20.0e-3", "Data 2, 1.0e-3 172:?:CRC" , "Data 6" }; and two List namely "KeyList" and "ValueList" like List<string> KeyList = new List<string>(); List<string> ValueList = new List<string>(); I need to fill the two List<String> from the data from l_lstRowData using Pattern Matching And here is my Pattern for this String l_strPattern = @"(?<KEY>(Data|data|DATA)\s[0-9]*[,]?[ ][0-9e.-]*)[ \t\r\n]*(?<Value>[0-9A-Za-z:?*!. \t\r\n\-]*)"; Regex CompiledPattern=new Regex(l_strPattern,RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace); So finally the two Lists will contain KeyList { "Data 1" } { "Data 3, 20.0e-3" } { "Data 2, 1.0e-3" } { "Data 6" } ValueList { "32:01805043*0FFFFFFF" } { "" } { "172:?:CRC" } { "" } Scenerio: The Group KEY in the Pattern Should match "The data followed by an integer value , and the if there exist a comma(,) then the next string i.e a double value The Group Value in the Pattern should match string after the whitespace.In the first string it should match 32:01805043*0FFFFFFF but in the 3rd 172:?:CRC. Here is my sample code for (int i = 0; i < l_lstRowData.Count; i++) { MatchCollection M = CompiledPattern.Matches(l_lstRowData[i], 0); KeyList.Add(M[0].Groups["KEY"].Value); ValueList.Add(M[0].Groups["Value"].Value); } But my Pattern is not working in this situation. Please help me to rewrite my Pattern.

  • javascript: Problems with multiple setIntervals running simultaniously

    - by user340879
    Hello, My first post here. I want to make a horizontal menu with submenu's sliding down on mouseover. I know I could use jQuery but this is to practice my javascript skills. I use the following code: var up = new Array() var down = new Array() var submenustart function titleover(headmenu, inter) { submenu = headmenu.lastChild up[inter] = window.clearInterval(up[inter]) down[inter] = window.setInterval("slidedown(submenu)",1) } function slidedown(submenu) { if(submenu.offsetTop < submenustart) { submenu.style.top = submenu.offsetTop + 1 + "px" } } function titleout(headmenu, inter) { submenu = headmenu.lastChild down[inter] = window.clearInterval(down[inter]) up[inter] = window.setInterval("slideup(submenu)", 1) } function slideup(submenu) { if(submenu.offsetTop > submenustart - submenu.clientHeight + 1) { submenu.style.top = submenu.offsetTop - 1 + "px" } } The variable submenustart gets appointed a value in another function which is not relevant for my question. HTML looks like this: <table class="hoofding" id="hoofding"> <tr> <td onmouseover="titleover(this, 0)" onmouseout="titleout(this, 0)"><a href="#" class="hoofdinglink" id="hoofd1">AAAA</a> <table class="menu"> <tr><td><a href="...">1111</a></td></tr> <tr><td><a href="...">2222</a></td></tr> <tr><td><a href="...">3333</a></td></tr> </table></td> <td onmouseover="titleover(this, 1)" onmouseout="titleout(this, 1)"><a href="#" class="hoofdinglink">BBBB</a> <table class="menu"> <tr><td><a href="...">1111</a></td></tr> <tr><td><a href="...">2222</a></td></tr> <tr><td><a href="...">3333</a></td></tr> <tr><td><a href="...">4444</a></td></tr> <tr><td><a href="...">5555</a></td></tr> </table></td> ... </tr> </table> What happens is the following: If I go over and out (for ex) menu A it works fine. If i go now over menu B the interval applied to A is now applied to B. There are now 2 interval functions applied to B. The one originally for A and a new one triggered by the mouseover on B. If I would go to A all the intervals are now applied to A. I have been searching for hours but and I am completely stuck. Thanks in advance.

  • What is the fastest (possibly unsafe) way to read a byte[]?

    - by Aidiakapi
    I'm working on a server project in C#, and after a TCP message is received, it is parsed, and stored in a byte[] of exact size. (Not a buffer of fixed length, but a byte[] of an absolute length in which all data is stored.) Now for reading this byte[] I'll be creating some wrapper functions (also for compatibility), these are the signatures of all functions I need: public byte ReadByte(); public sbyte ReadSByte(); public short ReadShort(); public ushort ReadUShort(); public int ReadInt(); public uint ReadUInt(); public float ReadFloat(); public double ReadDouble(); public string ReadChars(int length); public string ReadString(); The string is a \0 terminated string, and is probably encoded in ASCII or UTF-8, but I cannot tell that for sure, since I'm not writing the client. The data exists of: byte[] _data; int _offset; Now I can write all those functions manually, like this: public byte ReadByte() { return _data[_offset++]; } public sbyte ReadSByte() { byte r = _data[_offset++]; if (r >= 128) return (sbyte)(r - 256); else return (sbyte)r; } public short ReadShort() { byte b1 = _data[_offset++]; byte b2 = _data[_offset++]; if (b1 >= 128) return (short)(b1 * 256 + b2 - 65536); else return (short)(b1 * 256 + b2); } public short ReadUShort() { byte b1 = _data[_offset++]; return (short)(b1 * 256 + _data[_offset++]); } But I wonder if there's a faster way, not excluding the use of unsafe code, since this seems a little bit too much work for simple processing.

  • Set the amount of rows JList show (Java)

    - by Alex Cheng
    Hi all. Problem: I have a method that creates a list from the parsed ArrayList. I manage to show the list in the GUI, without scrollbar. However, I am having problem setting it to show only the size of ArrayList. Meaning, say if the size is 6, there should only be 6 rows in the shown List. Below is the code that I am using. I tried setting the visibleRowCount as below but it does not work. I tried printing out the result and it shows that the change is made. private void createSuggestionList(ArrayList<String> str) { int visibleRowCount = str.size(); System.out.println("visibleRowCount " + visibleRowCount); listForSuggestion = new JList(str.toArray()); listForSuggestion.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); listForSuggestion.setSelectedIndex(0); listForSuggestion.setVisibleRowCount(visibleRowCount); System.out.println(listForSuggestion.getVisibleRowCount()); listScrollPane = new JScrollPane(listForSuggestion); MouseListener mouseListener = new MouseAdapter() { @Override public void mouseClicked(MouseEvent mouseEvent) { JList theList = (JList) mouseEvent.getSource(); if (mouseEvent.getClickCount() == 2) { int index = theList.locationToIndex(mouseEvent.getPoint()); if (index >= 0) { Object o = theList.getModel().getElementAt(index); System.out.println("Double-clicked on: " + o.toString()); } } } }; listForSuggestion.addMouseListener(mouseListener); textPane.add(listScrollPane); repaint(); } To summarize: I want the JList to show as many rows as the size of the parsed ArrayList, without a scrollbar. Any ideas? Please help. Thanks. Please let me know if a picture of the problem is needed in case I did not phrase my question correctly.

  • Positioning objects in views during re-orientation in iPad

    - by Arni
    iPad Gurus: Apple wants us to support all orientations. I take that to mean that a particular layout should either rotate so that all objects are positioned relatively the same OR, if that doesn't look good, then they ought to be repositioned, OR two views ought to be designed and built. If I rely on the built-in rotation mechanism, the objects either get resized or they straddle the edge of the page in one orientation or the other, or they disappear from view altogether. I can't seem to find the right settings to get the objects to align clearly so they are seen in each orientation. Repositioning leads to a lot of if statements in the View Controller. So I don't think Apple had that in mind. I tried replacing views and even view controllers in "willRotateToInterfaceOrientation" method, but that either causes crashes or the portrait views end up in landscape unexpectedly and vv. Moreover, two view controllers means double the coding for the same view. There must be proper way to handle orientation changes, but I have searched the internet and documentation and sample code in vain for something that works. How is this done properly? Thanks!

  • How to change the handler position by dragging/single click on the slider

    - by Geetha
    Hi All, I am using the following files to create a slider. Problem:Needs double click to change the handler position first click: it move the handler but the following code is not working. a second later it return back to the previous position. second click on the handler in new position, before it moves back the following code is working. Needs: I want change the media player current position with the handler current position value by dragging the handler or single click on the new position of the slider. Ex: initial position of the handler: l-------------------------------- document.mediaPlayer.currentPosition = 0 After dragging it some other position ----------------------l---------- document.mediaPlayer.currentPosition = 125 Code: var endTime = document.mediaPlayer.SelectionEnd; $("#slider-constraints").slider({ animate: true, max: endTime, range: $R(0, endTime), value: 1, enforceConstraints: false, start:function(event,index){document.mediaPlayer.currentPosition=index.value; $('#slider-constraints').slider("constraints", [0, index.value]); $('#slider-constraints').slider("value", index.value);} }); window.setInterval(function() { $('#slider-constraints').slider("value", document.mediaPlayer.currentPosition); }, 4000);

  • Android AutocompleteView OnClickListener

    - by Chirag_RB
    I have 2 Auto Complete Views which i have to pre-populate with some text .However as soon as user clicks on the views , the text should disappear and allow user to enter text . I have written two separate on click listeners to do so . The On click listener for the first one is working fine . However i have to double click for the On click listener of the second one to work. Please find the chunk of code below and come up with some solution . final AutoCompleteTextView source = (AutoCompleteTextView) findViewById(R.id.source); ArrayAdapter source_adapter = new ArrayAdapter(this, R.layout.list_item, Model.City); source.setAdapter(source_adapter); source.setOnClickListener(new OnClickListener(){ public void onClick(View v) { source.setText(""); source.setTextSize(14); } }); final AutoCompleteTextView destination = (AutoCompleteTextView) findViewById(R.id.destination); ArrayAdapter destination_adapter = new ArrayAdapter(this, R.layout.list_item, Model.City); destination.setAdapter(destination_adapter); destination.setOnClickListener(new OnClickListener(){ public void onClick(View v) { destination.setText(""); destination.setTextSize(14); } });

  • Rotate a linked list

    I want to rotate a linked list that contains a number. 123 should be rotated to 231.

  • 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.

  • Number of characters recommended for a statement

    - by liaK
    Hi, I have been using Qt 4.5 and so do C++. I have been told that it's a standard practice to maintain the length of each statement in the application to 80 characters. Even in Qt creator we can make a right border visible so that we can know whether we are crossing the 80 characters limit. But my question is, Is it really a standard being followed? Because in my application, I use indenting and all, so it's quite common that I cross the boundary. Other cases include, there might be a error statement which will be a bit explanatory one and which is in an inner block of code, so it too will cross the boundary. Usually my variable names look bit lengthier so as to make the names meaningful. When I call the functions of the variable names, again I will cross. Function names will not be in fewer characters either. I agree a horizontal scroll bar shows up and it's quite annoying to move back and forth. So, for function calls including multiple arguments, when the boundary is reached I will make the forth coming arguments in the new line. But besides that, for a single statement (for e.g a very long error message which is in double quotes " " or like longfun1()->longfun2()->...) if I use an \ and split into multiple lines, the readability becomes very poor. So is it a good practice to have those statement length restrictions? If this restriction in statement has to be followed? I don't think it depends on a specific language anyway. I added C++ and Qt tags since if it might. Any pointers regarding this are welcome.

  • How to load/save C++ class instance (using STL containers) to disk

    - by supert
    I have a C++ class representing a hierarchically organised data tree which is very large (~Gb, basically as large as I can get away with in memory). It uses an STL list to store information at each node plus iterators to other nodes. Each node has only one parent, but 0-10 children. Abstracted, it looks something like: struct node { public: node_list_iterator parent; // iterator to a single parent node double node_data_array[X]; map<int,node_list_iterator> children; // iterators to child nodes }; class strategy { private: list<node> tree; // hierarchically linked list of nodes struct some_other_data; public: void build(); // build the tree void save(); // save the tree from disk void load(); // load the tree from disk void use(); // use the tree }; I would like to implement the load() and save() to disk, and it should be fairly fast, however the obvious problems are: I don't know the size in advance; The data contains iterators, which are volatile; My ignorance of C++ is prodigious. Could anyone suggest a pure C++ solution please?

  • How to strip out 0x0a special char from utf8 file using c# and keep file as utf8?

    - by user1013388
    The following is a line from a UTF-8 file from which I am trying to remove the special char (0X0A), which shows up as a black diamond with a question mark below: 2464577 ????? True s6620178 Unspecified <1?1009-672 This is generated when SSIS reads a SQL table then writes out, using a flat file mgr set to code page 65001. When I open the file up in Notepad++, displays as 0X0A. I'm looking for some C# code to definitely strip that char out and replace it with either nothing or a blank space. Here's what I have tried: string fileLocation = "c:\\MyFile.txt"; var content = string.Empty; using (StreamReader reader = new System.IO.StreamReader(fileLocation)) { content = reader.ReadToEnd(); reader.Close(); } content = content.Replace('\u00A0', ' '); //also tried: content.Replace((char)0X0A, ' '); //also tried: content.Replace((char)0X0A, ''); //also tried: content.Replace((char)0X0A, (char)'\0'); Encoding encoding = Encoding.UTF8; using (FileStream stream = new FileStream(fileLocation, FileMode.Create)) { using (BinaryWriter writer = new BinaryWriter(stream, encoding)) { writer.Write(encoding.GetPreamble()); //This is for writing the BOM writer.Write(content); } } I also tried this code to get the actual string value: byte[] bytes = { 0x0A }; string text = Encoding.UTF8.GetString(bytes); And it comes back as "\n". So in the code above I also tried replacing "\n" with " ", both in double quotes and single quotes, but still no change. At this point I'm out of ideas. Anyone got any advice? Thanks.

    Hello, Specifications: MySQL 4.1+ I've certain situation that requires certain result set from MySQL query, let's see the current query first & then ask my question: SELECT thread.dateline AS tdateline, post.dateline AS pdateline, MIN(post.dateline) FROM thread AS thread LEFT JOIN post AS post ON(thread.threadid = post.threadid) LEFT JOIN forum AS forum ON(thread.forumid = forum.forumid) WHERE post.postid != thread.firstpostid AND thread.open = 1 AND thread.visible = 1 AND thread.replycount >= 1 AND post.visible = 1 AND (forum.options & 1) AND (forum.options & 2) AND (forum.options & 4) AND forum.forumid IN(1,2,3) GROUP BY post.threadid ORDER BY tdateline DESC, pdateline ASC As you can see, mainly I need to select dateline of threads from 'thread' table, in addition to dateline of the second post of each thread, that's all under the conditions you see in the WHERE CLAUSE. Since each thread has many posts, and I need only one result per thread, I've used GROUP BY CLAUSE for that purpose. This query will return only one post's dateline with it's related unique thread. My questions are: How to limit returned threads per each forum!? Suppose I need only 5 threads -as a maximum- to be returned for each forum declared in the WHERE CLAUSE 'forum.forumid IN(1,2,3)', how can this be achieved. Is there any recommendations for optimizing this query (of course after solving the first point)? Notes: I prefer not to use sub-queries, but if it's the only solution available I'll accept it. Double queries not recommended. I'm sure there's a smart solution for this situation. Appreciated advice in advance :)

  • Copy object using pointer (templates)

    - by Azodious
    How the push_back of stl::vector is implemented so it can make copy of any datatype .. may be pointer, double pointer and so on ... I'm implementing a template class having a function push_back almost similar to vector. Within this method a copy of argument should be inserted in internal memory allocated memory. but the argument is a pointer. (an object pointer). Can you pls tell how to create copy from pointer. so that if i delete the pointer in caller still the copy exists in my template class? Code base is as follows: template<typename T> class Vector { public: void push_back(const T& val_in) { T* a = *(new T(val_in)); m_pData[SIZE++] = a; } } Caller: Vector<MyClass*> v(3); MyClass* a = new MyClass(); a->a = 0; a->b = .5; v.push_back(a); delete a; Thanks.

  • How can I create an instance of a class that I can use is more than one place in c#

    - by user1743574
    So I've been working on a class that details students of a university. I have one button that sets the details to a new instance of a class, and another to check if the student passed, through a method in my Class. The problem is that I create an instance of a class in the first button to add the values from what the user input, but I cannot use the second button to access the instance of the class created in the first button. private void button3_Click(object sender, EventArgs e) { Student student1 = new Student(); label1.Text = student1.text(); if (student1.hasPassed() == true) { passfailtextbox.Text = "Pass"; } else { passfailtextbox.Text = "Fail"; } } private void button1_Click(object sender, EventArgs e) { Student student1 = new Student(); student1.FirstName = firstnamebox.Text; student1.SecondName = secondnamebox.Text; student1.DateofBirth = DateTime.Parse(dobtextbox.Text).Date; student1.Course = coursetextbox.Text; student1.MatriculationNumber = int.Parse(matriculationtextbox.Text); student1.YearMark = double.Parse(yearmarktextbox.Text); } public Boolean hasPassed() { if (YearMark < 40) { return false; } else { return true; } } public string text() { return "Student" + " " + firstname + " " + secondname + " " + course + " " + dob.ToString() + " " + matriculationnumber.ToString() + " " + yearmark.ToString() ; }

  • Build a Drill Down TableView with arrays

    - by skiria
    I'm trying to build a Drill down tableview to show the information that I have in a hierachy of arrays and classes. I have 3 classes: class Video { nameVideo, id, description, user... } class Topic {nameTopic, topicID, NSMutableArray videos; } class Category {nameCategory, categoryID, NSMUtableArray topics} And then in my app delegate I defined //AppDelegate.h NSMutableArray categories; The app display the tableView with nameCategory, but then, when I select a row it shows a tableview with 0 rows. If I check, for the second view the NumberOfRowsInSection, it returns me 0. I supose that the error is that I don't build correctly the provisional array called tableDataSource, I don't know the reason why it doesn't copy the new information on this array. ` - (void)viewDidLoad { [super viewDidLoad]; appDelegate = (TSCAppDelegate *)[[UIApplication sharedApplication] delegate]; //self.title = @"Categoria"; if(CurrentLevel == 0) { //Initialize our table data source NSArray *tempArray = [[NSArray alloc] init]; self.tableDataSource = tempArray; [tempArray release]; self.tableDataSource = appDelegate.categories; self.navigationItem.title = @"Categoria"; CurrentTitle = @"Categoria"; } else { self.navigationItem.title = CurrentTitle; } } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } // Customize the number of rows in the table view. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog (@"contador_ %i,", [self.tableDataSource count]); //--> On the second view it is 0! return [self.tableDataSource count]; } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier]autorelease]; } // Configure the cell. if (CurrentLevel == 0) { Category *aCategory = [self.tableDataSource objectAtIndex:indexPath.row]; cell.text = aCategory.nameCategory; } if (CurrentLevel == 1) { Topic *aTopic = [self.tableDataSource objectAtIndex:indexPath.row]; cell.text = aTopic.nameTopic; } else if ([CurrentLevel == 0]){ Topic *aTopic = [self.tableDataSource objectAtIndex:indexPath.row]; cell.text = aTopic.nameTopic; //NSLog(@"inside!!"); } cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the actual Category Category *aCategory = [self.tableDataSource objectAtIndex:indexPath.row]; //NSLog (@" CATEGORY: %@", aCategory.nameCategory); //NSLog (@" CATEGORY: %i", aCategory.categoryID); //NSLog (@" TOPICS OF CATEGORY: %i", [aCategory.topics count]); //Prepare to tableview. navegaTableViewController *nvController = [[navegaTableViewController alloc] initWithNibName:@"navegaTableView" bundle:[NSBundle mainBundle]]; //Increment the Current View nvController.CurrentLevel += 1; //Set the title; nvController.CurrentTitle = @"Topic"; nvController.tableDataSource = aCategory.topics; //Push the new table view on the stack [self.navigationController pushViewController:nvController animated:YES]; [nvController release]; } `

  • Zend dubugger in eclipse - timeout everytime

    - by jax
    I am running a virtual server in the US. I am trying to get my eclipse machine at home (outside the USA), to connect to the USA server. I have setup Zend on the server. When I run phpinfo() I get the following zend output. Note: 1.2.3.4 will be the external WAN IP address of my ADSL router at home. Directive Local Value Master Value zend_debugger.allow_hosts 127.0.0.1,1.2.3.4 127.0.0.1,1.2.3.4 zend_debugger.allow_tunnel no value no value zend_debugger.deny_hosts no value no value zend_debugger.expose_remotely always always zend_debugger.httpd_uid -1 -1 zend_debugger.max_msg_size 2097152 2097152 zend_debugger.tunnel_max_port 65535 65535 zend_debugger.tunnel_min_port 1024 1024 So zend looks like it is working ok on the server side. When I run a debug session and select 'Test Debugger' I get a timeout every time. I have already added dummy.php to the root folder of the server. In 'installed debuggers' I double clicked on Zend and have put my external WAN IP address. I noticed that the port is 10000, I also have webmin running on this port on the server, will there be a conflict?

  • Preserving the order of annotations

    - by Ragunath Jawahar
    When obtaining the list of fields using getFields() and getDeclaredFields(), the order of the fields in a Java class is undefined. I need this order in my validation library. Since the order is not preserved (though some claim that the order is preserved in JDK 6 and above but is not guaranteed across VMs). I cannot speculate on this because the order of annotations across fields is absolutely essential for the library. One way to get around this is to have an order or an index attribute in my Annotation. What worries me is that the code could become a bit cumbersome for maintaining in the following case. If the use wants to insert a new annotated field then, he might have to renumber all the other annotations in the class. I could have the order or index as a floating point number - float or double but , it wouldn't look good to have order such as 1, 1.5, 2, etc., What would be an elegant solution for this problem? Here is a example code so that you can get an idea about the problem: @Required @TextRule (minLength = 6, message = "You need at least 6 characters.") private EditText usernameEditText; @Password private EditText passwordEditText; @ConfirmPassword private EditText confirmPasswordEditText; @Email private EditText emailEditText;

  • jQuery Hover Fade Button with an Active State

    - by Tim
    I do not want to double post a question; I was trying to post an add-on to my first question that I was looking for additional help. How does one go about this? Here is the original question. jQuery Hover Fade Button with an Active State Was hoping to see if there is a solution to the glitch I found. The problem I am now looking for help with is all other buttons still have the hover effect, but a button that was once active no longer does. <ul class="buttons"> <li><a class="button" href="#">button 1</a></li> <li><a class="button" href="#">button 2</a></li> <li><a class="button" href="#">button 3</a></li> </ul> Best way to explain this. If button 2 is clicked – it is now active. Buttons 1 and 3 will still hover. If you click on button 1 – it is now active and button 2 will no longer hover while button 3 will. Eventually when you go through the series of all buttons the animation hover is no longer.
