  • jQuery dialog width resizing problem

    - by ktMen
    I try to load some HTML code into a jQueryUI dialog by AJAX. The code itself is a list, where rightmost elements should be absolutely positioned so that the list looks like a table with two columns, but only in some rows. The problem is that jQueryUI plugin does not seem to be correctly resizing the dialog's width, which I think is due to the absolute positioning of some li's. I have read some answers to other similar questions, but none helped me out with this. This is the code I load: <style type="text/css"> ul {list-style-type:none;margin:0px;padding:0px;} ul ul {margin:0px;padding:0px;} ul>li.fila {margin-bottom:5px;padding-bottom:5px;} ul li.fila ul li { display:inline; padding-left:20px; position:relative; margin-bottom:10px; } ul li.fila ul li.O { background:url(bullet.gif) 5px 8px no-repeat; list-style-position:inside; } </style> <ul id="raiz" > <li class="fila"> <ul > <li style="position:absolute;left:0px;" class="O"> <label for="col1">Col1:</label> <input type="text" name="col1" id="col1" value="vCol1" class="text ui-widget-content ui-corner-all" /> </li> <li style="left:250px;" class="O" > <label for="col2">Col2:</label> <input type="text" name="col2" id="col2" value="vCol2" class="text ui-widget-content ui-corner-all" /> </li> </ul> </li> <li class="fila"> <ul > <li> <label for="col3">Col3:</label> <input type="text" name="col3" id="col3" value="vCol3" class="text ui-widget-content ui-corner-all" /> </li> </ul> </li> </ul> And the Dialog constructor: $("#dialog").dialog({ bgiframe: true, autoOpen: false, height: 'auto', width: 'auto', modal: true, buttons:{ 'Cancel': function() { $(this).dialog('close'); } }, open: function(event,ui){ $("#dialog").load("dialogCode.html"); } }); Thanks in advance for any suggestions.

  • How to designing a generic databse whos layout may change over time?

    - by mawg
    Here's a tricky one - how do I programatically create and interrogate a database who's contents I can't really foresee? I am implementing a generic input form system. The user can create PHP forms with a WYSIWYG layout and use them for any purpose he wishes. He can also query the input. So, we have three stages: a form is designed and generated. This is a one-off procedure, although the form can be edited later. This designs the database. someone or several people make use of the form - say for daily sales reports, stock keeping, payroll, etc. Their input to the forms is written to the database. others, maybe management, can query the database and generate reports. Since these forms are generic, I can't predict the database structure - other than to say that it will reflect HTML form fields and consist of a the data input from collection of edit boxes, memos, radio buttons and the like. Questions and remarks: A) how can I best structure the database, in terms of tables and columns? What about primary keys? My first thought was to use the control name to identify each column, then I realized that the user can edit the form and rename, so that maybe "name" becomes "employee" or "wages" becomes ":salary". I am leaning towards a unique number for each. B) how best to key the rows? I was thinking of a timestamp to allow me to query and a column for the row Id from A) C) I have to handle column rename/insert/delete. Foe deletion, I am unsure whether to delete the data from the database. Even if the user is not inputting it from the form any more he may wish to query what was previously entered. Or there may be some legal requirements to retain the data. Any gotchas in column rename/insert/delete? D) For the querying, I can have my PHP interrogate the database to get column names and generate a form with a list where each entry has a database column name, a checkbox to say if it should be used in the query and, based on column type, some selection criteria. That ought to be enough to build searches like "position = 'senior salesman' and salary 50k". E) I probably have to generate some fancy charts - graphs, histograms, pie charts, etc for query results of numerical data over time. I need to find some good FOSS PHP for this. F) What else have I forgotten? This all seems very tricky to me, but I am database n00b - maybe it is simple to you gurus?

  • Function-Local Static Const variable Initialization semantics.

    - by Hassan Syed
    The questions are in bold, for those that cannot be bothered reading a question in depth. This is a followup to this question. It is to do with the initialization semantics of static variables in functions. Static variables should be initialized once, and their internal state might be altered later - as I (currently) do in the linked question. However, the code in question does not require the feature to change the state of the variable later. Let me clarrify my position, since I don't require the string object's internal state to change. The code is for a trait class for meta programming, and as such would would benifit from a const char * const ptr -- thus Ideally a local cost static const variable is needed. My educated guess is that in this case the string in question will be optimally placed in memory by the link-loader, and that the code is more secure and maps to the intended semantics. This leads to the semantics of such a variable "The C++ Programming language Third Edition -- Stroustrup" does not have anything (that I could find) to say about this matter. All that is said is that the variable is initialized once when the flow of control of the thread first reaches the code. This leads me to ponder if the following code would be sensible, and if not what are the intended semantics ?. #include <iostream> const char * const GetString(const char * x_in) { static const char * const x = x_in; return x; } int main() { const char * const temp = GetString("yahoo"); std::cout << temp << std::endl; const char * const temp2 = GetString("yahoo2"); std::cout << temp2 << std::endl; } The following compiles on GCC and prints "yahoo" twice. Which is what I want -- However it might not be standards compliant (which is why I post this question). It might be more elegant to have two functions, "SetString" and "String" where the latter forwards to the first. If it is standards compliant does someone know of a templates implementation in boost (or elsewhere) ?

  • jQuery, get datas in AJAX (done) then, display them as star (error)

    - by Tristan
    Hello, In my website, there are 2 steps : I get values from another domain with AJAX, it's numbers 100% working Then, i want to display those numbers in stars with this plugin (http://stackoverflow.com/questions/1987524/turn-a-number-into-star-rating-display-using-jquery-and-css) The error : the stars plugin does not work for the value i recieve from my ajax request, but it's working for my values for my domain which are not JS manipulated you can see a demo here http://www.esl.eu/fr/test/test_atome/?killcache=true PS: the data in ajax are provided in JSON-P so i wrote a parser which look like this: jQuery.ajax({ type: "get", dataType: "jsonp", url: "http://www.foo.com/", data: {demandeur: "monkey" }, cache: true, success: function(data, textStatus, XMLHttpRequest){ var obj = null, length = data.length; for (var i = 0; i < length; i++) { widget = "<p>AVERAGES<p>"; widget += "<p><span class='stars'>"; widget += data[i].services; widget += "</span></p>"; widget += "<p><span class='stars'>"; widget += data[i].qualite; widget += "</span></p>"; jQuery('#gotserv').html(widget); } } }); }); Then i have the star plugin after this function : $.fn.stars = function() { $(this).each(function() { // Get the value var val = parseFloat($(this).html()); // Make sure that the value is in 0 - 5 range val = val 5 ? 5 : (val < 0 ? 0 : val); // Calculate physical size var size = 16 * val; // Create stars holder var stars = $(''); // Adjust yellow stars' width stars.find('span').width(size); // Replace the numerical value with stars $(this).replaceWith(stars); }); I hope you understand, i don't know if i'm clear Thank you

  • Variable sized packet structs with vectors

    - by Rev316
    Lately I've been diving into network programming, and I'm having some difficulty constructing a packet with a variable "data" property. Several prior questions have helped tremendously, but I'm still lacking some implementation details. I'm trying to avoid using variable sized arrays, and just use a vector. But I can't get it to be transmitted correctly, and I believe it's somewhere during serialization. Now for some code. Packet Header class Packet { public: void* Serialize(); bool Deserialize(void *message); unsigned int sender_id; unsigned int sequence_number; std::vector<char> data; }; Packet ImpL typedef struct { unsigned int sender_id; unsigned int sequence_number; std::vector<char> data; } Packet; void* Packet::Serialize(int size) { Packet* p = (Packet *) malloc(8 + 30); p->sender_id = htonl(this->sender_id); p->sequence_number = htonl(this->sequence_number); p->data.assign(size,'&'); //just for testing purposes } bool Packet::Deserialize(void *message) { Packet *s = (Packet*)message; this->sender_id = ntohl(s->sender_id); this->sequence_number = ntohl(s->sequence_number); this->data = s->data; } During execution, I simply create a packet, assign it's members, and send/receive accordingly. The above methods are only responsible for serialization. Unfortunately, the data never gets transferred. Couple of things to point out here. I'm guessing the malloc is wrong, but I'm not sure how else to compute it (i.e. what other value it would be). Other than that, I'm unsure of the proper way to use a vector in this fashion, and would love for someone to show me how (code examples please!) :) Edit: I've awarded the question to the most comprehensive answer regarding the implementation with a vector data property. Appreciate all the responses!

  • Advice for Architecture Design Logic for software application

    - by Prasad
    Hi, I have a framework of basic to complex set of objects/classes (C++) running into around 500. With some rules and regulations - all these objects can communicate with each other and hence can cover most of the common queries in the domain. My Dream: I want to provide these objects as icons/glyphs (as I learnt recently) on a workspace. All these objects can be dragged/dropped into the workspace. They have to communicate only through their methods(interface) and in addition to few iterative and conditional statements. All these objects are arranged finally to execute a protocol/workflow/dataflow/process. After drawing the flow, the user clicks the Execute/run button. All the user interaction should be multi-touch enabled. The best way to show my dream is : Jeff Han's Multitouch Video. consider Jeff is playing with my objects instead of the google maps. :-) it should be like playing a jigsaw puzzle. Objective: how can I achieve the following while working on this final product: a) the development should be flexible to enable provision for web services b) the development should enable easy web application development c) The development should enable client-server architecture - d) further it should also enable mouse based drag/drop desktop application like Adobe programs etc. I mean to say: I want to economize on investments. Now I list my efforts till now in design : a) Created an Editor (VB) where the user writes (manually) the object / class code b) On Run/Execute, the code is copied into a main() function and passed to interpreter. c) Catch the output and show it in the console. The interpreter can be separated to become a server and the Editor can become the client. This needs lot of standard client-server architecture work. But some how I am not comfortable in the tightness of this system. Without interpreter is there much faster and better embeddable solution to this? - other than writing a special compiler for these objects. Recently learned about AXIS-C++ can help me - looks like - a friend suggested. Is that the way to go ? Here are my questions: (pl. consider me a self taught programmer and NOT my domain) a) From the stage of C++ objects to multi-touch product, how can I make sure I will develop the parallel product/service models as well.? What should be architecture aspects I should consider ? b) What technologies are best suited for this? c) If I am thinking of moving to Cloud Computing, how difficult/ how redundant / how unnecessary my efforts will be ? d) How much time in months would it take to get the first beta ? I take the liberty to ask if any of the experts here are interested in this project, please email me: [email protected] Thank you for any help. Looking forward.

  • How to I serialize a large graph of .NET object into a SQL Server BLOB without creating a large bu

    - by Ian Ringrose
    We have code like: ms = New IO.MemoryStream bin = New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bin.Serialize(ms, largeGraphOfObjects) dataToSaveToDatabase = ms.ToArray() // put dataToSaveToDatabase in a Sql server BLOB But the memory steam allocates a large buffer from the large memory heap that is giving us problems. So how can we stream the data without needing enough free memory to hold the serialized objects. I am looking for a way to get a Stream from SQL server that can then be passed to bin.Serialize() so avoiding keeping all the data in my processes memory. Likewise for reading the data back... Some more background. This is part of a complex numerical processing system that processes data in near real time looking for equipment problems etc, the serialization is done to allow a restart when there is a problem with data quality from a data feed etc. (We store the data feeds and can rerun them after the operator has edited out bad values.) Therefore we serialize the object a lot more often then we de-serialize them. The objects we are serializing include very large arrays mostly of doubles as well as a lot of small “more normal” objects. We are pushing the memory limit on a 32 bit system and make the garage collector work very hard. (Effects are being made elsewhere in the system to improve this, e.g. reusing large arrays rather then create new arrays.) Often the serialization of the state is the last straw that courses an out of memory exception; our peak memory usage is while this serialization is being done. I think we get large memory pool fragmentation when we de-serialize the object, I expect there are also other problem with large memory pool fragmentation given the size of the arrays. (This has not yet been investigated, as the person that first looked at this is a numerical processing expert, not a memory management expert.) Are customers use a mix of Sql Server 2000, 2005 and 2008 and we would rather not have different code paths for each version of Sql Server if possible. We can have many active models at a time (in different process, across many machines), each model can have many saved states. Hence the saved state is stored in a database blob rather then a file. As the spread of saving the state is important, I would rather not serialize the object to a file, and then put the file in a BLOB one block at a time. Other related questions I have asked How to Stream data from/to SQL Server BLOB fields? Is there a SqlFileStream like class that works with Sql Server 2005?

  • Best Practices / Patterns for Enterprise Protection/Remediation of SSNs (Social Security Numbers)

    - by Erik Neu
    I am interested in hearing about enterprise solutions for SSN handling. (I looked pretty hard for any pre-existing post on SO, including reviewing the terriffic SO automated "Related Questions" list, and did not find anything, so hopefully this is not a repeat.) First, I think it is important to enumerate the reasons systems/databases use SSNs: (note—these are reasons for de facto current state—I understand that many of them are not good reasons) Required for Interaction with External Entities. This is the most valid case—where external entities your system interfaces with require an SSN. This would typically be government, tax and financial. SSN is used to ensure system-wide uniqueness. SSN has become the default foreign key used internally within the enterprise, to perform cross-system joins. SSN is used for user authentication (e.g., log-on) The enterprise solution that seems optimum to me is to create a single SSN repository that is accessed by all applications needing to look up SSN info. This repository substitutes a globally unique, random 9-digit number (ASN) for the true SSN. I see many benefits to this approach. First of all, it is obviously highly backwards-compatible—all your systems "just" have to go through a major, synchronized, one-time data-cleansing exercise, where they replace the real SSN with the alternate ASN. Also, it is centralized, so it minimizes the scope for inspection and compliance. (Obviously, as a negative, it also creates a single point of failure.) This approach would solve issues 2 and 3, without ever requiring lookups to get the real SSN. For issue #1, authorized systems could provide an ASN, and be returned the real SSN. This would of course be done over secure connections, and the requesting systems would never persist the full SSN. Also, if the requesting system only needs the last 4 digits of the SSN, then that is all that would ever be passed. Issue #4 could be handled the same way as issue #1, though obviously the best thing would be to move away from having users supply an SSN for log-on. There are a couple of papers on this: UC Berkely: http://bit.ly/bdZPjQ Oracle Vault: bit.ly/cikbi1

  • Display lable character by character using javascript

    Hi, I am creating Hang a Man using PHP, MySQL & Javascript. Every thing is going perfect, I get a word randomly from DB show it as a label apply it a class where display = none. Now when I click on a Character that character become disable fine which i actually want but the label-character does not show. My code is: <link href="style.css" rel="stylesheet" type="text/css" media="screen" /> <?php include( 'config.php' ); $question = questions(); // Get question. $alpha = alphabats(); // Get alphabets. ?> <script language="javascript"> function clickMe( name ){ var question = '<?php echo $question; ?>'; var questionLen = <?php echo strlen($question); ?>; for ( var i = 0; i < questionLen; i++ ){ if ( question[i] == name ){ var link = document.getElementById( name ); link.style.display = 'none'; var label = document.getElementById( 'questionLabel' + i ); label.style.display = 'none'; } } } </script> <div> <table align="center" style="border:solid 1px"> <tr> <?php for ( $i = 0; $i < 26; $i++ ) { echo "<td><a href='#' id=$alpha[$i] name=$alpha[$i] onclick=clickMe('$alpha[$i]');>". $alpha[$i] ."</a>&nbsp;</td>"; } ?> </tr> </table> <br/> <table align="center" style="border:solid 1px"> <tr> <?php for ( $i = 0; $i < strlen($question); $i++ ) { echo "<td class='question'><label id=questionLabel$i >". $question[$i] ."</label></td>"; } ?> </tr> </table> </div>

  • Is Java assert broken?

    - by BlairHippo
    While poking around the questions, I recently discovered the assert keyword in Java. At first, I was excited. Something useful I didn't already know! A more efficient way for me to check the validity of input parameters! Yay learning! But then I took a closer look, and my enthusiasm was not so much "tempered" as "snuffed-out completely" by one simple fact: you can turn assertions off.* This sounds like a nightmare. If I'm asserting that I don't want the code to keep going if the input listOfStuff is null, why on earth would I want that assertion ignored? It sounds like if I'm debugging a piece of production code and suspect that listOfStuff may have been erroneously passed a null but don't see any logfile evidence of that assertion being triggered, I can't trust that listOfStuff actually got sent a valid value; I also have to account for the possibility that assertions may have been turned off entirely. And this assumes that I'm the one debugging the code. Somebody unfamiliar with assertions might see that and assume (quite reasonably) that if the assertion message doesn't appear in the log, listOfStuff couldn't be the problem. If your first encounter with assert was in the wild, would it even occur to you that it could be turned-off entirely? It's not like there's a command-line option that lets you disable try/catch blocks, after all. All of which brings me to my question (and this is a question, not an excuse for a rant! I promise!): What am I missing? Is there some nuance that renders Java's implementation of assert far more useful than I'm giving it credit for? Is the ability to enable/disable it from the command line actually incredibly valuable in some contexts? Am I misconceptualizing it somehow when I envision using it in production code in lieu of statements like if (listOfStuff == null) barf();? I just feel like there's something important here that I'm not getting. *Okay, technically speaking, they're actually off by default; you have to go out of your way to turn them on. But still, you can knock them out entirely.

    I have a particular scenario below. The code below should print 'say()' function of B and C class and print 'B says..' and 'C says...' but it doesn't .Any ideas.. I am learning polymorphism so also have commented few questions related to it on the lines of code below. class A { public: // A() {} virtual void say() { std::cout << "Said IT !

  • Why is it still so hard to write software?

    - by nornagon
    Writing software, I find, is composed of two parts: the Idea, and the Implementation. The Idea is about thinking: "I have this problem; how do I solve it?" and further, "how do I solve it elegantly?" The answers to these questions are obtainable by thinking about algorithms and architecture. The ideas come partially through analysis and partially through insight and intuition. The Idea is usually the easy part. You talk to your friends and co-workers and you nut it out in a meeting or over coffee. It takes an hour or two, plus revisions as you implement and find new problems. The Implementation phase of software development is so difficult that we joke about it. "Oh," we say, "the rest is a Simple Matter of Code." Because it should be simple, but it never is. We used to write our code on punch cards, and that was hard: mistakes were very difficult to spot, so we had to spend extra effort making sure every line was perfect. Then we had serial terminals: we could see all our code at once, search through it, organise it hierarchically and create things abstracted from raw machine code. First we had assemblers, one level up from machine code. Mnemonics freed us from remembering the machine code. Then we had compilers, which freed us from remembering the instructions. We had virtual machines, which let us step away from machine-specific details. And now we have advanced tools like Eclipse and Xcode that perform analysis on our code to help us write code faster and avoid common pitfalls. But writing code is still hard. Writing code is about understanding large, complex systems, and tools we have today simply don't go very far to help us with that. When I click "find all references" in Eclipse, I get a list of them at the bottom of the window. I click on one, and I'm torn away from what I was looking at, forced to context switch. Java architecture is usually several levels deep, so I have to switch and switch and switch until I find what I'm really looking for -- by which time I've forgotten where I came from. And I do that all day until I've understood a system. It's taxing mentally, and Eclipse doesn't do much that couldn't be done in 1985 with grep, except eat hundreds of megs of RAM. Writing code has barely changed since we were staring at amber on black. We have the theoretical groundwork for much more advanced tools, tools that actually work to help us comprehend and extend the complex systems we work with every day. So why is writing code still so hard?

  • Dependency property does not work within a geometry in a controltemplate

    - by Erik Bongers
    I have a DepencencyProperty (a boolean) that works fine on an Ellipse, but not on an ArcSegment. Am I doing something that is not possible? Here's part of the xaml. Both the TemplateBindings of Origin and LargeArc do not work in the geometry. But the LargeArc DependencyProperty does work in the Ellipse, so my DependencyProperty seems to be set up correctly. <ControlTemplate TargetType="{x:Type nodes:TestCircle}"> <Canvas Background="AliceBlue"> <Ellipse Height="10" Width="10" Fill="Yellow" Visibility="{TemplateBinding LargeArc, Converter={StaticResource BoolToVisConverter}}"/> <Path Canvas.Left="0" Canvas.Top="0" Stroke="Black" StrokeThickness="3"> <Path.Data> <GeometryGroup> <PathGeometry> <PathFigure IsClosed="True" StartPoint="{TemplateBinding Origin}"> <LineSegment Point="150,100" /> <ArcSegment Point="140,150" IsLargeArc="{TemplateBinding LargeArc}" Size="50,50" SweepDirection="Clockwise"/> </PathFigure> </PathGeometry> </GeometryGroup> </Path.Data> </Path> </Canvas> </ControlTemplate> What I'm trying to build is a (sort of) pie-shaped usercontrol where the shape of the Pie is defined by DependencyProperties and the actual graphics used are in a template, so they can be replaced or customized. In other words: I would like the code-behind to be visual-free (which, I assume, is good separation). SOLUTION--------------------------(I'm not allowed to answer my own questions yet) I found the answer myself, and this can be useful for others encountering the same issue. This is why the TemplateBinding on the Geometry failed: A TemplateBinding will only work when binding a DependencyProperty to another DependencyProperty. Following article set me on the right track: http://blogs.msdn.com/b/liviuc/archive/2009/12/14/wpf-templatebinding-vs-relativesource-templatedparent.aspx The ArcSegment properties are no DependencyProperties. Thus, the solution to the above problem is to replace <ArcSegment Point="140,150" IsLargeArc="{TemplateBinding LargeArc}" with <ArcSegment Point="140,150" IsLargeArc="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=LargeArc}" Colin, your working example where an 'ordinary' binding was used in the geometry set me on the right track. BTW, love the infographics and the construction of your UserControl in your blogpost. And, hey, that quick tip on code snippets, and especially on that DP attribute and the separation of those DPs into a partial class file is pure gold!

  • How hard programming is? Really. [closed]

    - by Bubba88
    Hi! The question is about your perception of programming activity. How hard/exacting this task is? There is much buzz about programming nowadays, people say that programmers are smart, very technical and abstract at a time, know much about world, psychology etc.. They say, that programmers got really powerful brain thing, cause there is much to keep in consideration simultaneously again with much information folded into each other associatively (up 10 levels of folding they say))) Still, there are some terms to specify at our own.. So that is the question: What do you think about programming in general? Is it hard? Is it 'for everyone' or for the particular kind of people only? How much non-CS background do you need to program (just to program, really; enterprise applications for example)? How long is the learning curve? (again, for programming in general) And another bunch of random questions: - If you were not to like/love programming, would that be a serious trouble bothering your current employment? - If you were to start from the beginning, would you chose that direction this time? - What other areas (jobs or maybe hobbies) are comparable to programming in the way they can explode someone's lovely brain? - Is 'non turing-complete programming' (SQL, XML, etc.) comparable to what we do or is it really way easier, less requiring, cheap and akin to cooking :)? Well, the essence is: How would you describe programming activity WRT to its difficulty? Or, on the other hand: Did you ever catch yourself thinking at some point: OMG, it's sooo hard! I don't know how would I ever program, even carried away this way and doing programming just for fun? It's very interesting to know your opinion, your'e the programmers after all. I mean much people must be exaggerating/speculating about the thing they do not really know about. But that musn't be the case here on SO :) P.S.: I'll try my best to update this post later, and you please edit it too. At least I'll get decent English in my question text :)

  • Creating a column of RadioButtons in Adobe Flex

    - by adnan
    I am having an un-predictable behavior of creating radio buttons in advancedDataGrid column using itemRenderer. Similar kind of problem has been reported at http://stackoverflow.com/questions/112036/creating-a-column-of-radiobuttons-in-adobe-flex. I tried to use the same procedure i.e. bind every radio button selectedValue and value attributes with the property specified in the property of the associated bean but still facing the problem. The button change values! The selected button becomes deselected, and unselected ones become selected. Here is the code of my advancedDataGrid: <mx:AdvancedDataGrid id="adDataGrid_rptdata" width="100%" height="100%" dragEnabled="false" sortableColumns="false" treeColumn="{action}" liveScrolling="false" displayItemsExpanded="true" > <mx:dataProvider> <mx:HierarchicalData source="{this.competenceCollection}" childrenField="competenceCriteria"/> </mx:dataProvider> <mx:columns> <mx:AdvancedDataGridColumn headerText="" id="action" dataField="criteriaName" /> <mx:AdvancedDataGridColumn headerText="Periode 1" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period1" value="{data}" selected="{data.period1}" group="{data.radioBtnGrpArray[0]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn headerText="Periode 2" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period2" value="{data}" selected="{data.period2}" group="{data.radioBtnGrpArray[1]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn headerText="Periode 3" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period3" value="{data}" selected="{data.period3}" group="{data.radioBtnGrpArray[2]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> </mx:columns> </mx:AdvancedDataGrid> Any work around is highly appreciated in this regard!

  • How do I de-duplicate a list of nodes in XSLT - and return the last node encountered?

    - by Broam
    I've seen lots of "de-duplicate this xml" questions but everyone wants the first node or the nodes are identical. I have a bit of a bigger puzzle. I have a list of articles in XML, a relevant snippet is shown: <item><key>Article1</key><stamp>100</stamp></item> <item><key>Article1</key><stamp>130</stamp></item> <item><key>Article2</key><stamp>800</stamp></item> <item><key>Article1</key><stamp>180</stamp></item> <item><key>Article3</key><stamp>900</stamp></item> <item><key>Article3</key><stamp>950</stamp></item> <item><key>Article4</key><stamp>990</stamp></item> <item><key>Article5</key><stamp>999</stamp></item> I'd like a list of nodes where the keys are unique and where the last instance is returned, not the first: Stamp (integer) is always increasing for elements of a particular key. Ideally I'd like "largest stamp" but they're always in order so the shortcut is ok. Desired result: (Order doesn't really matter.) <item><key>Article2</key><stamp>800</stamp></item> <item><key>Article1</key><stamp>180</stamp></item> <item><key>Article3</key><stamp>950</stamp></item> <item><key>Article4</key><stamp>990</stamp></item> <item><key>Article5</key><stamp>999</stamp></item> I'm somewhat confused on how to get this list. Any ideas? I'm using the Saxon processor if it matters.

  • What Can I Do To One Of My Team Number (Good Friend As Well) Who Lost His Passion.

    - by skyflyer
    It seems this question is not program related, but there are lot of similar questions. So please bear with me! By the way, I am programmer and my team is also charging a software project. And SO is the only place which solved me lot of thorny troubles!THANK YOU GUYS! I joined my company with him years ago. At that time he was quite passionate on his job which is a front-end development. He gave us lot of useful suggestions concerning his work like design. And I believed he was a smart guy. I believe he still is smart too by the way. One years later, however, he seemed lost his passion and fooling around every day, did not care about his work any more and produced poorwork. Even worse he literally stopped learning new skills and honing his work related skills. For me it is horrible, we got to keep abreast with new technology development, otherwise we will be throw out. Since we were just coworkers, I did not care about it too much except mentioned my thoughts several times. But last month, we resembled a new group and assigned very important project. And I am the team leader, sadly! My boss gave me lot of support and expectation as well. I did a pretty good job before and I am very optimism to our future. But as a team, if my team does not work hard, we will be doomed to failure no matter how hard I work and push. In order to revitalize his passion, I tried couple of ways like talking to him about my concern and my boss's angry. I offered his new task which is quite new to him. I even persuaded my boss to give him new incentive package. But all of them knocked wall. His reaction was just he did not care. Even worse he did not want to talk about his situation. I want to be hard on him, but since we are friends and coworkers, I really can not see it will work. Even it works, I can not so quickly change my self from friend and coworker into manager. As a novice in management, I am really overwhelmed! I do not want get him fired, we are friends and I do not see him fired as my team number. What can I do? Thank you guys!

  • Performance Optimization for Matrix Rotation

    - by Summer_More_More_Tea
    Hello everyone: I'm now trapped by a performance optimization lab in the book "Computer System from a Programmer's Perspective" described as following: In a N*N matrix M, where N is multiple of 32, the rotate operation can be represented as: Transpose: interchange elements M(i,j) and M(j,i) Exchange rows: Row i is exchanged with row N-1-i A example for matrix rotation(N is 3 instead of 32 for simplicity): ------- ------- |1|2|3| |3|6|9| ------- ------- |4|5|6| after rotate is |2|5|8| ------- ------- |7|8|9| |1|4|7| ------- ------- A naive implementation is: #define RIDX(i,j,n) ((i)*(n)+(j)) void naive_rotate(int dim, pixel *src, pixel *dst) { int i, j; for (i = 0; i < dim; i++) for (j = 0; j < dim; j++) dst[RIDX(dim-1-j, i, dim)] = src[RIDX(i, j, dim)]; } I come up with an idea by inner-loop-unroll. The result is: Code Version Speed Up original 1x unrolled by 2 1.33x unrolled by 4 1.33x unrolled by 8 1.55x unrolled by 16 1.67x unrolled by 32 1.61x I also get a code snippet from pastebin.com that seems can solve this problem: void rotate(int dim, pixel *src, pixel *dst) { int stride = 32; int count = dim >> 5; src += dim - 1; int a1 = count; do { int a2 = dim; do { int a3 = stride; do { *dst++ = *src; src += dim; } while(--a3); src -= dim * stride + 1; dst += dim - stride; } while(--a2); src += dim * (stride + 1); dst -= dim * dim - stride; } while(--a1); } After carefully read the code, I think main idea of this solution is treat 32 rows as a data zone, and perform the rotating operation respectively. Speed up of this version is 1.85x, overwhelming all the loop-unroll version. Here are the questions: In the inner-loop-unroll version, why does increment slow down if the unrolling factor increase, especially change the unrolling factor from 8 to 16, which does not effect the same when switch from 4 to 8? Does the result have some relationship with depth of the CPU pipeline? If the answer is yes, could the degrade of increment reflect pipeline length? What is the probable reason for the optimization of data-zone version? It seems that there is no too much essential difference from the original naive version. EDIT: My test environment is Intel Centrino Duo processor and the verion of gcc is 4.4 Any advice will be highly appreciated! Kind regards!

  • replacing div content with a click using jquery

    - by Joel
    I see this question asked a lot in the related questions, but my need seems very simple compared to those examples, and sadly I'm just still too new at js to know what to remove...so at the risk of being THAT GUY, I'm going to ask my question... I'm trying to switch out the div contents in a box depending on the button pushed. Right now I have it working using the animatedcollapse.toggle function, but it doesn't look very good. I want to replace it with a basic fade in on click and fade in new content on next button. Basic idea: <div> <ul> <li><a href="this will fade in the first_div"></li> <li><a href="this will fade in the second_div"></li> <li><a href="this will fade in the third_div"></li> </ul> <div class="first_container"> <ul> <li>stuff</li> <li>stuff</li> <li>stuff</li> </ul> </div> <div class="second_container"> <ul> <li>stuff</li> <li>stuff</li> <li>stuff</li> </ul> </div> <div class="third_container"> <ul> <li>stuff</li> <li>stuff</li> <li>stuff</li> </ul> </div> </div> I've got everything working with the animated collapse, but it's just an ugly effect for this situation, so I want to change it out. Thanks! Joel

  • How to limit results in a SharePoint XSL query

    - by David
    Hello all, I am creating a SharePoint site that we will use to report issues with trucks used in our business. Linked to the list I have created will be a page that will display an overview of the trucks and a little truck icon will show the trucks current status. Green and the truck is okay (no open issues), Red and the truck have an open issue with status "Undrivable", Orange and there is two issues open that requires the user to look further into the truck before using it and finally a Gray truck for when there is a new issue created that has not been looked into (not sure if it is drivable or not). I have managed to create the "Dashboard" and with my limit XSL/XPATH knowledge been able to add a truck and replicate the description above but... in my test I have created 4 issues, for example if three of them are changed to status Closed and one left to Undrivable I will get four icons on the page, three with Green trucks and the last one Red. So in theory it works but I obviously only want to see the last truck, one truck. I am not interested in seeing the others. <xsl:template name="dvt_1.rowview"> <xsl:variable name="CountReport" select="count(/dsQueryResponse/Rows/Row[@Highloader='GGEU12' and @Status!='Closed'])" /> <xsl:variable name="MoreThan" select="$CountReport &gt; 1" /> <xsl:variable name="NoReports" select="$CountReport = 0" /> <xsl:variable name="Closed" select=" @Highloader='GGEU12' and @Status='Closed'" /> <xsl:choose> <xsl:when test="$MoreThan"> <div class="ms-vb"><img title='More than one report exist!' border='0' alt='In Progress' src='highloader/Library/hl-orange.png' /></div> </xsl:when> <xsl:otherwise> <div class="ms-vb"><xsl:value-of disable-output-escaping="yes" select="@Icon" /></div> </xsl:otherwise> </xsl:choose> </xsl:template> My hope is that someone with slightly more knowledge can find the last piece of the puzzle for me! Thanks for reading and asking questions to fill any gap I left above. David

  • Where is the method call in the EXE file?

    - by Victor Hurdugaci
    Introduction After watching this video from LIDNUG, about .NET code protection http://secureteam.net/lidnug_recording/Untitled.swf (especially from 46:30 to 57:30), I would to locate the call to a MessageBox.Show in an EXE I created. The only logic in my "TrialApp.exe" is: public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { MessageBox.Show("This is trial app"); } } Compiled on the Release configuration: http://rapidshare.com/files/392503054/TrialApp.exe.html What I do to locate the call Run the application in WinDBG and break after the message box appears. Get the CLR stack with !clrstack: 0040e840 5e21350b [InlinedCallFrame: 0040e840] System.Windows.Forms.SafeNativeMethods.MessageBox(System.Runtime.InteropServices.HandleRef, System.String, System.String, Int32) 0040e894 5e21350b System.Windows.Forms.MessageBox.ShowCore(System.Windows.Forms.IWin32Window, System.String, System.String, System.Windows.Forms.MessageBoxButtons, System.Windows.Forms.MessageBoxIcon, System.Windows.Forms.MessageBoxDefaultButton, System.Windows.Forms.MessageBoxOptions, Boolean) 0040e898 002701f0 [InlinedCallFrame: 0040e898] 0040e934 002701f0 TrialApp.Form1.Form1_Load(System.Object, System.EventArgs) Get the MethodDesc structure (using the address of Form1_Load) !ip2md 002701f0 MethodDesc: 001762f8 Method Name: TrialApp.Form1.Form1_Load(System.Object, System.EventArgs) Class: 00171678 MethodTable: 00176354 mdToken: 06000005 Module: 00172e9c IsJitted: yes CodeAddr: 002701d0 Transparency: Critical Source file: D:\temp\TrialApp\TrialApp\Form1.cs @ 22 Dump the IL of this method (by MethodDesc) !dumpil 001762f8 IL_0000: ldstr "This is trial app" IL_0005: call System.Windows.Forms.MessageBox::Show IL_000a: pop IL_000b: ret So, as the video mentioned, the call to to Show is 5 bytes from the beginning of the method implementation. Now I open CFFExplorer (just like in the video) and get the RVA of the Form1_Load method: 00002083. After this, I go to Address Converter (again in CFF Explorer) and navigate to offset 00002083. There we have: 32 72 01 00 00 70 28 16 00 00 0A 26 2A 7A 03 2C 13 02 7B 02 00 00 04 2C 0B 02 7B 02 00 00 04 6F 17 00 00 0A 02 03 28 18 00 00 0A 2A 00 03 30 04 00 67 00 00 00 00 00 00 00 02 28 19 00 00 0A 02 In the video is mentioned that the first 12 bytes are for the method header so I skip them 2A 7A 03 2C 13 02 7B 02 00 00 04 2C 0B 02 7B 02 00 00 04 6F 17 00 00 0A 02 03 28 18 00 00 0A 2A 00 03 30 04 00 67 00 00 00 00 00 00 00 02 28 19 00 00 0A 02 5 bytes from the beginning of the implementation should be the opcode for method call (28). Unfortunately, is not there. 02 7B 02 00 00 04 2C 0B 02 7B 02 00 00 04 6F 17 00 00 0A 02 03 28 18 00 00 0A 2A 00 03 30 04 00 67 00 00 00 00 00 00 00 02 28 19 00 00 0A 02 Questions: What am I doing wrong? Why there is no method call at that position in the file? Or maybe the video is missing some information... Why the guy in that video replaces the call with 9 zeros?

  • Under what circumstances is an SqlConnection automatically enlisted in an ambient TransactionScope T

    - by Triynko
    What does it mean for an SqlConnection to be "enlisted" in a transaction? Does it simply mean that commands I execute on the connection will participate in the transaction? If so, under what circumstances is an SqlConnection automatically enlisted in an ambient TransactionScope Transaction? See questions in code comments. My guess to each question's answer follows each question in parenthesis. Scenario 1: Opening connections INSIDE a transaction scope using (TransactionScope scope = new TransactionScope()) using (SqlConnection conn = ConnectToDB()) { // Q1: Is connection automatically enlisted in transaction? (Yes?) // // Q2: If I open (and run commands on) a second connection now, // with an identical connection string, // what, if any, is the relationship of this second connection to the first? // // Q3: Will this second connection's automatic enlistment // in the current transaction scope cause the transaction to be // escalated to a distributed transaction? (Yes?) } Scenario 2: Using connections INSIDE a transaction scope that were opened OUTSIDE of it //Assume no ambient transaction active now SqlConnection new_or_existing_connection = ConnectToDB(); //or passed in as method parameter using (TransactionScope scope = new TransactionScope()) { // Connection was opened before transaction scope was created // Q4: If I start executing commands on the connection now, // will it automatically become enlisted in the current transaction scope? (No?) // // Q5: If not enlisted, will commands I execute on the connection now // participate in the ambient transaction? (No?) // // Q6: If commands on this connection are // not participating in the current transaction, will they be committed // even if rollback the current transaction scope? (Yes?) // // If my thoughts are correct, all of the above is disturbing, // because it would look like I'm executing commands // in a transaction scope, when in fact I'm not at all, // until I do the following... // // Now enlisting existing connection in current transaction conn.EnlistTransaction( Transaction.Current ); // // Q7: Does the above method explicitly enlist the pre-existing connection // in the current ambient transaction, so that commands I // execute on the connection now participate in the // ambient transaction? (Yes?) // // Q8: If the existing connection was already enlisted in a transaction // when I called the above method, what would happen? Might an error be thrown? (Probably?) // // Q9: If the existing connection was already enlisted in a transaction // and I did NOT call the above method to enlist it, would any commands // I execute on it participate in it's existing transaction rather than // the current transaction scope. (Yes?) }

  • CSS precedence order? My lecture slides are correct or not?

    - by Michael Mao
    Hi all: I've noticed that there are a couple of similar questions and answers at SO already, but let me clarify my specific question here first: I've got lecture slides which states like this: To be frank, I haven't heard of this rule of css precedence myself, and I googled to find something with similar topic but not quite like that : here To have a test myself, I've made a test page on my own server here After running it on FireFox 3.6.3, I am sure it does not show the way as it should be, according to the statement in lecture slides: imported stylesheet ? am I doing it wrong? I cannot see its effect using FireBug it says that embedded stylesheet has a higher precedence over linked/imported stylesheets, however, it doesn't work, if I put the linked/imported tag AFTER that. inline style vs html attributes ? I've got an image where I firstly set its inline style to control the width and height, then use direct html attributes width/height to try modifying that, but failed... Below is the source code : <html> <head> <style type="text/css"> #target { border : 2px solid green; color : green; } </style> <link rel="stylesheet" href="./linked.css" type="text/css" media="screen" /> </head> <body> <div id="target">A targeted div tag on page.</div> <img src="cat.jpg" alt="" style="width : 102px; height : 110px;" width="204px" height="220px" /> </body> </html> Can any experienced CSS guys help me figure out if the slide is correct or not? Frankly speaking, I am puzzled myself, as I can clearly see some other "incorrect" statements here and there amongst the slides, such as JavaScript is on client-side (how about server-side JavaScript?) and "Embedded styles are in the head section of a web page "(what the heck? I am not allowed to put it inside the body tag?) Sorry about this silly question, the exam is on TOMORROW, and I now see a lot of things to think about :)

  • How to retain the state of a activity that has a GLSurfaceView

    - by user348639
    My problem is our game can switch into menu and setting mode instantly but it will need 4-6 seconds to load texture, init GL render mode eventually I just used 6 simple textures to create 6 sprites in game. Please help me answer two questions: 1. How can I preload our assets in android os to start our game quicker? 2. In order to use a trick to create instance switch between activity, how can I retain my activity with GLSurfaceView state? I order to help you understanding my situation, please read the following code: The game using 3 activities as you can see in following configuration: <application android:label="@string/app_name" android:icon="@drawable/icon" android:allowBackup="true"> <activity android:name=".Menu" android:screenOrientation="portrait" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:launchMode="singleTop"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".ReTouch" android:screenOrientation="portrait" /> <activity android:name=".Preference" android:screenOrientation="portrait" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" /> </application> My .ReTouch class is a class that extended from RokonActivity (I am using rokon engine for my game), this engine will create a GLSurefaceView to render my game in OpenGL ES You can get RokonAcitivity's source code here: http://code.google.com/p/rokon/source/browse/tags/release/1.1.1/src/com/stickycoding/Rokon/RokonActivity.java public class ReTouch extends RokonActivity { public static final int REPLAY_DELAY_INTERVAL = 1000; private ReTouchGameBoard reTouchGame; and .Menu, .Preference are two normal standard activity in an android application. I am using this method to start and switch between activities: playButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { soundPool.play(soundId, 1, 1, 1, 0, 1); startActivity(new Intent(Menu.this, ReTouch.class)); } }); settingButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { soundPool.play(soundId, 1, 1, 1, 0, 1); startActivity(new Intent(Menu.this, Preference.class)); } }); quitButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { soundPool.play(soundId, 1, 1, 1, 0, 1); finish(); } });

  • PHP Processes reaching limit along with FastCGI timeouts

    - by Constant M
    I have a problem similar to http://stackoverflow.com/questions/1168384/how-to-troubleshoot-php-processes, but with a twist. We have a couple of managed servers that recently migrated to FastCGI. Since then we've been having problems. We have a content management system at a central place that we manage all our sites with. All the sites run on the same managed server. So basically its one PHP script that generates pages on the same server. The catch comes in where it works perfectly on some, and gives FCGI timeout errors on others. At the same time our support is saying that the PHP processes heap up to their limit and then causes Apache to stop working. I'm convinced this is a fault on their side, but would like to get my side clean too. Anyway have any suggestions where I can start looking for what's going wrong? I know it's a really broad question, but any help or pointers would be great. Thanks Just to add to that, here's a PS printout from support: happyh 13853 21556 0 01:04 ? 00:00:00 /usr/bin/php5-cgi happyh 13869 13853 0 01:04 ? 00:00:00 /usr/bin/php5-cgi mamedc 13914 21556 0 05:14 ? 00:00:00 /usr/bin/php5-cgi wealthf 13947 21556 0 01:21 ? 00:00:00 /usr/bin/php5-cgi wealthf 13961 13947 0 01:21 ? 00:00:00 /usr/bin/php5-cgi mamedc 14032 13914 0 05:14 ? 00:00:00 /usr/bin/php5-cgi lookgrt 14157 21556 0 04:47 ? 00:00:00 /usr/bin/php5-cgi lookgrt 14178 14157 0 04:47 ? 00:00:00 /usr/bin/php5-cgi wolfie 14262 21556 0 01:08 ? 00:00:00 /usr/bin/php5-cgi wolfie 14276 14262 0 01:08 ? 00:00:00 /usr/bin/php5-cgi yaukrl 14352 21556 0 01:21 ? 00:00:00 /usr/bin/php5-cgi yaukrl 14361 14352 0 01:21 ? 00:00:00 /usr/bin/php5-cgi itpays2 14538 21556 0 01:33 ? 00:00:00 /usr/bin/php5-cgi itpays2 14547 14538 0 01:33 ? 00:00:00 /usr/bin/php5-cgi brichmbx 14732 21556 0 04:47 ? 00:00:00 /usr/bin/php5-cgi brichmbx 14803 14732 0 04:47 ? 00:00:00 /usr/bin/php5-cgi greatl 14969 21556 0 01:00 ? 00:00:00 /usr/bin/php5-cgi
