  • PDF Report generation

    - by IniTech
    EDIT : I completed this project using ABCpdf. For anyone interested, I love this product and their support is A+. Everything I listed as a 'Con' for the HTML - PDF solution was easily doable in ABCpdf. I've been charged with creating a data driven pdf report. After reviewing the plethora of options, I have narrowed it down to 2. I need you all to to help me decide, or offer alternatives I haven't considered. Here are the requirements: 100% Data driven Eventually PDF (a stop in HTML is fine, so long as it is converted) Can be run with multiple sets of data (the layout is always the same, the data is variable) Contains normal analysis-style copy (saved in DB with html markup) Contains tables (data for tables is generated at run-time) Header/Page # on each page Table of Contents .NET (VB or C#) Done quickly Now, because of the fact that the report is going to be generated with multiple sets of data, I don't think a stamped pdf template will work since I won't know how long or how many pages a certain piece of the report could require. So, I think my best options are: Programmatic creation using an iText-like solution. Generate in HTML and convert to PDF using a third-party application (ABCPdf is the tool I have played with so far) Both solutions have their pro's and con's. Programmatic solution: Pros: Flexible Easy page numbering/page header/table of contents Free Cons: Time consuming (to write a layer on top of iText to do what I need and keep maintainable) Since the copy is already stored in the db with html markup, I would have to parse through the data before I place it into the pdf, ensuring I don't have to break the paragraph into chunks so I can apply bold, italic, underline, etc. to specific phrases. This seems like a huge PITA, and I hope I am wrong about that assumption. HTML - PDF Pros: Easy to generate from db (no parsing necessary) Many tools for conversion Uses technology I am already familiar with Built-in "Print Preview" - not a req, but nice Cons: (Edited after project completion. All of my assumptions were incorrect and ABCpdf is awesome) 1. Almost impossible to generate page headers - Not True 2. Very difficult to generate page numbers Not True 3. Nearly impossible to generate table of contents Not True 4. (Cross-browser support isn't a con; Since its internal, I can dictate what browser to use) 5. Conversion tool quirks - may not convert exactly as rendered in browser Not True 6. Overall, I think it would be very hard to format the HTML exactly as I would want it to appear/convert to PDF. Not True That's it - I need the communitys help in deciding which way I should go. I might be wrong about some of my Pro/Con assumptions. If I am, please tell me. All thoughts and suggestions are welcome and appreciated. Thanks

  • PHP - Cannot modify header information...

    - by Scott W.
    Hi, I am going crazy with this error: Cannot modify header information - headers already sent by... Please note that I know about the gazillion results on google and on stack overflow. My problem is the way I've constructed my pages. To keep html separate from php, I use include files. So, for example, my pages look something like this: <?php require_once('web.config.php'); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Login</title> <link rel="shortcut icon" href="images/favicon.gif"/> <link rel="shortcut icon" href="images/favicon.ico"/> <link rel="stylesheet" type="text/css" href="<?php echo SITE_STYLE; ?>"/> </head> <body> <div id="page_effect" style="display:none;"> <?php require_once('./controls/login/login.control.php'); ?> </div> </body> </html> So, by the time my php file is included, the header is already sent. Part of the include file looks like this: // redirect to destination if($user_redirect != 'default') { $destination_url = $row['DestinationUrl']; header('Location:'.$user_redirect); } elseif($user_redirect == 'default' && isset($_GET['ReturnURL'])) { $destination_url = $_GET['ReturnURL']; header('Location:'.$destination_url); } else { header('Location:'.SITE_URL.'login.php'); } But I can't figure out how to work around this. I can't have the header redirect before the output so having output buffering on is the only thing I can do. Naturally it works fine that way - but having to rely on that just stinks. It would be nice if PHP had an alternative way to redirect or had additional parameters to tell it to clear the buffer.

  • Multiplying matrices: error: expected primary-expression before 'struct'

    - by justin
    I am trying to write a program that is supposed to multiply matrices using threads. I am supposed to fill the matrices using random numbers in a thread. I am compiling in g++ and using PTHREADS. I have also created a struct to pass the data from my command line input to the thread so it can generate the matrix of random numbers. The sizes of the two matrices are also passed in the command line as well. I keep getting: main.cpp:7: error: expected primary-expression before 'struct' my code @ line 7 =: struct a{ int Arow; int Acol; int low; int high; }; My inpust are : Sizes of two matrices ( 4 arguments) high and low ranges in which o generate the random numbers between. Complete code: [headers] using namespace std; void *matrixACreate(struct *); void *status; int main(int argc, char * argv[]) { int Arow = atoi(argv[1]); // Matrix A int Acol = atoi(argv[2]); // WxX int Brow = atoi(argv[3]); // Matrix B int Bcol = atoi(argv[4]); // XxZ, int low = atoi(argv[5]); // Range low int high = atoi(argv[6]); struct a{ int Arow; // Matrix A int Acol; // WxX int low; // Range low int high; }; pthread_t matrixAthread; //pthread_t matrixBthread; pthread_t runner; int error, retValue; if (Acol != Brow) { cout << " This matrix cannot be multiplied.

  • Exporting classes containing std:: objects (vector, map, etc) from a dll

    - by RnR
    I'm trying to export classes from a DLL that contain objects such as std::vectors and std::stings - the whole class is declared as dll export through: class DLL_EXPORT FontManager { The problem is that for members of the complex types I get this warning: warning C4251: 'FontManager::m__fonts' : class 'std::map<_Kty,_Ty' needs to have dll-interface to be used by clients of class 'FontManager' with [ _Kty=std::string, _Ty=tFontInfoRef ] I'm able to remove some of the warnings by putting the following forward class declaration before them even though I'm not changing the type of the member variables themselves: template class DLL_EXPORT std::allocator<tCharGlyphProviderRef>; template class DLL_EXPORT std::vector<tCharGlyphProviderRef,std::allocator<tCharGlyphProviderRef> >; std::vector<tCharGlyphProviderRef> m_glyphProviders; Looks like the forward declaration "injects" the DLL_EXPORT for when the member is compiled but is it safe? Does it realy change anything when the client compiles this header and uses the std container on his side? Will it make all future uses of such a container DLL_EXPORT (and possibly not inline?)? And does it really solve the problem that the warning tries to warn about? Is this warning anything I should be worried about or would it be best to disable it in the scope of these constructs? The clients and the dll will always be built using the same set of libraries and compilers and those are header only classes... I'm using Visual Studio 2003 with the standard STD library. ---- Update ---- I'd like to target you more though as I see the answers are general and here we're talking about std containers and types (such as std::string) - maybe the question really is: Can we disable the warning for standard containers and types available to both the client and the dll through the same library headers and treat them just as we'd treat an int or any other built-in type? (It does seem to work correctly on my side.) If so would should be the conditions under which we can do this? Or should maybe using such containers be prohibited or at least ultra care taken to make sure no assignment operators, copy constructors etc will get inlined into the dll client? In general I'd like to know if you feel designing a dll interface having such objects (and for example using them to return stuff to the client as return value types) is a good idea or not and why - I'd like to have a "high level" interface to this functionality... maybe the best solution is what Neil Butterworth suggested - creating a static library?

  • Infinite loop when adding a row to a list in a class in python3

    - by Margaret
    I have a script which contains two classes. (I'm obviously deleting a lot of stuff that I don't believe is relevant to the error I'm dealing with.) The eventual task is to create a decision tree, as I mentioned in this question. Unfortunately, I'm getting an infinite loop, and I'm having difficulty identifying why. I've identified the line of code that's going haywire, but I would have thought the iterator and the list I'm adding to would be different objects. Is there some side effect of list's .append functionality that I'm not aware of? Or am I making some other blindingly obvious mistake? class Dataset: individuals = [] #Becomes a list of dictionaries, in which each dictionary is a row from the CSV with the headers as keys def field_set(self): #Returns a list of the fields in individuals[] that can be used to split the data (i.e. have more than one value amongst the individuals def classified(self, predicted_value): #Returns True if all the individuals have the same value for predicted_value def fields_exhausted(self, predicted_value): #Returns True if all the individuals are identical except for predicted_value def lowest_entropy_value(self, predicted_value): #Returns the field that will reduce <a href="http://en.wikipedia.org/wiki/Entropy_%28information_theory%29">entropy</a> the most def __init__(self, individuals=[]): and class Node: ds = Dataset() #The data that is associated with this Node links = [] #List of Nodes, the offspring Nodes of this node level = 0 #Tree depth of this Node split_value = '' #Field used to split out this Node from the parent node node_value = '' #Value used to split out this Node from the parent Node def split_dataset(self, split_value): fields = [] #List of options for split_value amongst the individuals datasets = {} #Dictionary of Datasets, each one with a value from fields[] as its key for field in self.ds.field_set()[split_value]: #Populates the keys of fields[] fields.append(field) datasets[field] = Dataset() for i in self.ds.individuals: #Adds individuals to the datasets.dataset that matches their result for split_value datasets[i[split_value]].individuals.append(i) #<---Causes an infinite loop on the second hit for field in fields: #Creates subnodes from each of the datasets.Dataset options self.add_subnode(datasets[field],split_value,field) def add_subnode(self, dataset, split_value='', node_value=''): def __init__(self, level, dataset=Dataset()): My initialisation code is currently: if __name__ == '__main__': filename = (sys.argv[1]) #Takes in a CSV file predicted_value = "# class" #Identifies the field from the CSV file that should be predicted base_dataset = parse_csv(filename) #Turns the CSV file into a list of lists parsed_dataset = individual_list(base_dataset) #Turns the list of lists into a list of dictionaries root = Node(0, Dataset(parsed_dataset)) #Creates a root node, passing it the full dataset root.split_dataset(root.ds.lowest_entropy_value(predicted_value)) #Performs the first split, creating multiple subnodes n = root.links[0] n.split_dataset(n.ds.lowest_entropy_value(predicted_value)) #Attempts to split the first subnode.

  • java multipart POST library

    - by tom
    Is there a multipart POST library out there that achieve the same effect of doing a POST from a html form? for example - upload a file programmingly in Java versus upload the file using a html form. And on the server side, it just blindly expect the request from client side to be a multipart POST request and parse out the data as appropriate. Has anyone tried this? specifically, I am trying to see if I can simulate the following with Java The user creates a blob by submitting an HTML form that includes one or more file input fields. Your app sets blobstoreService.createUploadUrl() as the destination (action) of this form, passing the function a URL path of a handler in your app. When the user submits the form, the user's browser uploads the specified files directly to the Blobstore. The Blobstore rewrites the user's request and stores the uploaded file data, replacing the uploaded file data with one or more corresponding blob keys, then passes the rewritten request to the handler at the URL path you provided to blobstoreService.createUploadUrl(). This handler can do additional processing based on the blob key. Finally, the handler must return a headers-only, redirect response (301, 302, or 303), typically a browser redirect to another page indicating the status of the blob upload. Set blobstoreService.createUploadUrl as the form action, passing the application path to load when the POST of the form is completed. <body> <form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data"> <input type="file" name="myFile"> <input type="submit" value="Submit"> </form> </body> Note that this is how the upload form would look if it were created as a JSP. The form must include a file upload field, and the form's enctype must be set to multipart/form-data. When the user submits the form, the POST is handled by the Blobstore API, which creates the blob. The API also creates an info record for the blob and stores the record in the datastore, and passes the rewritten request to your app on the given path as a blob key.

  • WPF: Improving Performance for Running on Older PCs

    - by Phil Sandler
    So, I'm building a WPF app and did a test deployment today, and found that it performed pretty poorly. I was surprised, as we are really not doing much in the way of visual effects or animations. I deployed on two machines: the fastest and the slowest that will need to run the application (the slowest PC has an Intel Celeron 1.80GHz with 2GB RAM). The application ran pretty well on the faster machine, but was choppy on the slower machine. And when I say "choppy", I mean the cursor jumped even just passing it over any open window of the app that had focus. I opened the Task Manager Performance window, and could see that the CPU usage jumped whenever the app had focus and the cursor was moving over it. If I gave focus to another (e.g. Excel), the CPU usage went back down after a second. This happened on both machines, but the choppiness was only noticeable on the slower machine. I had very limited time to tinker on the deployment machines, so didn't do a lot of detailed testing. The app runs fine on my development machine, but I also see the CPU spiking up to 10% there, just running the cursor over the window. I downloaded the WPF performance tool from MS and have been tinkering with it (on my dev machine). The docs say this about the "Frame Rate" metric in the Perforator tool: For applications without animation, this value should be near 0. The app is not doing any heavy animation, but the frame rate stays near 50 when the cursor is over any window. The screens I tested on have column headers in a grid that "highlight" and buttons that change color and appearance when scrolled over. Even moving the mouse on blank areas of the windows cause the same Frame rate and CPU usage (doesn't seem to be related to these minor animations). (Also, I am unable to figure out how to get anything but the two default tools--Perforator and Visual Profiler--installed into the WPF performance tool. That is probably a separate question). I also have Redgate's profiling tool, but I'm not sure if that can shed any light on rendering performance. So, I realize this is not an easy thing to troubleshoot without specifics or sample code (which I can't post). My questions are: What are some general things to look for (or avoid) in the code to improve performance? What steps can I take using the WPF performance tool to narrow down the problem? Is the PC spec listed above (Intel Celeron 1.80GHz with 2GB RAM) too slow to be running even vanilla WPF applications?

  • How to properly preload images, js and css files?

    - by Kenny Bones
    Hi, I'm creating a website from scratch and I was really into this in the late 90's but the web has changed alot since then! And I'm more of a designer so when I started putting this site together, I basically did a system of php includes to make the site more "dynamic" When you first visit the site, you'll be presented to a logon screen, if you're not already logged on (cookies). If you're not logged on, a page called access.php is introdused. I thought I'd preload the most heavy images at this point. So that when the user is done logging on, the images are already cached. And this is working as I want. But I still notice that the biggest image still isn't rendered immediatly anyway. So it's seems kinda pointless. All of this has made me rethink how the site is structured and how scripts and css files are loaded. Using FireBug and YSlow with Firefox I see a few pointers like expires headers and reducing the size of each script. But is this really the culprit? For example, would this be really really stupid in the main index.php? The entire site is basically structured like this <?php require("dbconnect.php"); ?> <?php include ("head.php"); ?> And below this is basically just the body and the content of the site. Head.php however consists of the doctype, head portions, linking of two css style sheets, jQuery library, jQuery validation engine, Cufon and Cufon font file, and then the small Cufon.Replace snippet. The rest of the body comes with the index.php file, but at the bottom of this again is an include of a file called "footer.php" which basically consists of loading of a couple of jsLoader scripts and a slidepanel and then a js function. All of this makes the end page source look like a typical complete webpage, but I'm wondering if any of you can see immediatly that "this is really really stupid" and "don't do that, do this instead" etc. :) Are includes a bad way to go? This site is also pretty image intensive and I can probably do a little more optimization. But I don't think that's its the primary culprit. YSlow gives me a report of what takes up the most space: doc(1) - 5.8K js(5) - 198.7K css(2) - 5.6K cssimage(8) - 634.7K image(6) - 110.8K I know it looks like it's cssimage(8) that weighs the most, but I've already preloaded these images from before and it doesn't really affect the rendering.

  • C++ DLL creation for C# project - No functions exported

    - by Yeti
    I am working on a project that requires some image processing. The front end of the program is C# (cause the guys thought it is a lot simpler to make the UI in it). However, as the image processing part needs a lot of CPU juice I am making this part in C++. The idea is to link it to the C# project and just call a function from a DLL to make the image processing part and allow to the C# environment to process the data afterwards. Now the only problem is that it seems I am not able to make the DLL. Simply put the compiler refuses to put any function into the DLL that I compile. Because the project requires some development time testing I have created two projects into a C++ solution. One is for the Dll and another console application. The console project holds all the files and I just include the corresponding header into my DLL project file. I thought the compiler should take out the functions that I marked as to be exported and make the DLL from them. Nevertheless this does not happens. Here it is how I defined the function in the header: extern "C" __declspec(dllexport) void _stdcall RobotData(BYTE* buf, int** pToNewBackgroundImage, int* pToBackgroundImage, bool InitFlag, ObjectInformation* robot1, ObjectInformation* robot2, ObjectInformation* robot3, ObjectInformation* robot4, ObjectInformation* puck); extern "C" __declspec(dllexport) CvPoint _stdcall RefPointFinder(IplImage* imgInput, CvRect &imgROI, CvScalar &refHSVColorLow, CvScalar &refHSVColorHi ); Followed by the implementation in the cpp file: extern "C" __declspec(dllexport) CvPoint _stdcall RefPointFinder(IplImage* imgInput, CvRect &imgROI,&refHSVColorLow, CvScalar &refHSVColorHi ) { \\... return cvPoint((int)( M10/M00) + imgROI.x, (int)( M01/M00 ) + imgROI.y) ;} extern "C" __declspec(dllexport) void _stdcall RobotData(BYTE* buf, int** pToNewBackgroundImage, int* pToBackgroundImage, bool InitFlag, ObjectInformation* robot1, ObjectInformation* robot2, ObjectInformation* robot3, ObjectInformation* robot4, ObjectInformation* puck) { \\ ...}; And my main file for the DLL project looks like: #ifdef _MANAGED #pragma managed(push, off) #endif /// <summary> Include files. </summary> #include "..\ImageProcessingDebug\ImageProcessingTest.h" #include "..\ImageProcessingDebug\ImageProcessing.h" BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved) { return TRUE; } #ifdef _MANAGED #pragma managed(pop) #endif Needless to say it does not work. A quick look with DLL export viewer 1.36 reveals that no function is inside the library. I don't get it. What I am doing wrong ? As side not I am using the C++ objects (and here it is the C++ DLL part) such as the vector. However, only for internal usage. These will not appear in the headers of either function as you can observe from the previous code snippets. Any ideas? Thx, Bernat

  • Linker Issues with boost::thread under linux using Eclipse and CMake

    - by OcularProgrammer
    I'm in the process of attempting to port some code across from PC to Ubuntu, and am having some issues due to limited experience developing under linux. We use CMake to generate all our build stuff. Under windows I'm making VS2010 projects, and under Linux I'm making Eclipse projects. I've managed to get my OpenCV stuff ported across successfully, but am having major headaches trying to port my threaded boost apps. Just so we're clear, the steps I have followed so-far on a clean Ubuntu 12 installation. (I've done 2 clean re-installs to try and fix potential library cock-ups, now I'm just giving up and asking): Install Eclipse and Eclipse CDT using my package manager Install CMake and CMake Gui using my package manager Install libboost-all-dev using my package manager So-far that's all I've done. I can create the eclipse project using CMake with no errors, so CMake is successfully finding my boost install. When I try and build through eclipse is when I get issues; The app I'm attempting to build uses boost::asio for some UDP I/O and boost::thread to create worker threads for the asio I/O services. I can successfully compile each module, but when I come to link I get spammed with errors such as: /usr/bin/c++ CMakeFiles/RE05DevelopmentDemo.dir/main.cpp.o CMakeFiles/RE05DevelopmentDemo.dir/RE05FusionListener/RE05FusionListener.cpp.o CMakeFiles/RE05DevelopmentDemo.dir/NewEye/NewEye.cpp.o -o RE05DevelopmentDemo -rdynamic -Wl,-Bstatic -lboost_system-mt -lboost_date_time-mt -lboost_regex-mt -lboost_thread-mt -Wl,-Bdynamic /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_thread-mt.a(thread.o): In function `void boost::call_once<void (*)()>(boost::once_flag&, void (*)()) [clone .constprop.98]': make[2]: Leaving directory `/home/david/Code/Build/Support/RE05DevDemo' (.text+0xc8): undefined reference to `pthread_key_create' /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_thread-mt.a(thread.o): In function `boost::this_thread::interruption_enabled()': (.text+0x540): undefined reference to `pthread_getspecific' make[1]: Leaving directory `/home/david/Code/Build/Support/RE05DevDemo' /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_thread-mt.a(thread.o): In function `boost::this_thread::disable_interruption::disable_interruption()': (.text+0x570): undefined reference to `pthread_getspecific' /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_thread-mt.a(thread.o): In function `boost::this_thread::disable_interruption::disable_interruption()': (.text+0x59f): undefined reference to `pthread_getspecific' Some Gotchas that I have collected from other StackOverflow posts and have already checked: The boost libs are all present at /usr/lib I am not getting any compile errors for inability to find the boost headers, so they must be getting found. I am trying to link statically, but I believe eclipse should be passing the correct arguments to make that happen since my CMakeLists.txt includes SET(Boost_USE_STATIC_LIBS ON) I'm officially out of ideas here, I have tried doing local builds of boost and a bunch of other stuff with no more success. I even re-installed Ubuntu to ensure I haven't completely fracked the libs directories and links with multiple weird versions or anything else. Any help would be muchly appreciated.

  • jQuery ajax multiline "script" response

    - by Rendrik
    I'm designing a template creation tool, which uses a jQuery Ajax request that posts parameters to a PHP file. The PHP does the actual generation of the template's HTML. // Send for processing. Expect JS back to execute. function generate() { $.ajax({ type: "POST", url: "generate.php", data: $('#genform :input').serialize(), dataType: "script", beforeSend: function() { $("#loading").html("<img src='images/loadbar.gif' />"); $("#loading") .dialog({ height: 80, width: 256, autoOpen: true, modal: true }); }, success: function(data) { $("#loading").dialog('close'); } }); } My trouble is that I have the ajax dataType: set to "script". Using this, the PHP file generates some jQuery dialogs for any errors which works nicely. However, after I generate the HTML, i'm having trouble passing it back. So I have probably 100 lines of generated HTML and javascript which i'd like to work with. In the PHP file, i've tried: echo('$("#result").html("'.$html.'");'); This does actually work if there are NO line breaks in $html. As soon as there are any line breaks, the Chrome debugger reports "gen.html:1 Uncaught SyntaxError: Unexpected token ILLEGAL". It's obvious that it's trying to eval the returned response headers, but is stopping at any line break. So, to be clear, when I pass $html back, if the contents are this: $html = "<div>hi there</div>"; It works fine (all of my error message dialogs are one line). But if it's: $html = "<div> hi there </div>"; It blows up. I'm really not sure how to get around this, or if there's a better way to go about it. It's important to me to keep the formatting so people can copy the HTML template. I may just break down and display the template file on the PHP page if I can't solve this, but I was really hoping to keep everything within the confines of the HTML page.

  • Remove specific definitions from a variable in PHP

    - by Amit
    Hi everyone, I have a PHP mail script that validates name, email address, and phone number before sending the mail. This then means that the Name, Email address, and Phone fields are Required Fields. I want to have it so that the Name and EITHER Email or Phone are required. Such that if a name and phone are inputted, it sends the mail, or if a name and an email are inputted, it also sends the email. The way the script works right now is it has several IF statements that check for (1) name, (2) email and (3) phone. Here's an example of an if statement of the code: if ( ($email == "") ) { $errors .= $emailError; // no email address entered $email_error = true; } if ( !(preg_match($match,$email)) ) { $errors .= $invalidEmailError; // checks validity of email $email_error = true; } And here's how it sends the mail: if ( !($errors) ) { mail ($to, $subject, $message, $headers); echo "<p id='correct'>"; echo "?????? ????? ??????!"; echo "</p>"; } else { if (($email_error == true)) { $errors != $phoneError; /*echo "<p id='errors'>"; echo $errors; echo "</p>";*/ } if (($phone_error == true)) { $errors != $emailError; $errors != $invalidEmailError; /*echo "<p id='errors'>"; echo $errors; echo "</p>";*/ } echo "<p id='errors'>"; echo $errors; echo "</p>"; } This doesn't work though. Basically this is what I want to do: If no email address was entered or if it was entered incorrectly, set a variable called $email_error to be true. Then check for that variable, and if it's true, then remove the $phoneError part of the $errors variable. Man I hope I'm making some sense here. Does anyone know why this doesn't work? It reports all errors if all fields are left empty :( Thanks! Amit

  • How to add fadeIn and fadeOut to idTabs plugin's JS snippet?

    - by iMagdy
    Hi, I am using the jQuery plugin idTabs [ [www.sunsean.com/idTabs][1] ] and it allows me to line tabs and tabs' content via element#id and element href="#id" Ok, so I use this snippet: <script type="text/javascript"> $(document).ready(function() { $("#requestPool").idTabs(); $(".tabs").idTabs(); $(".miniTabs").idTabs(".active"); $(".switchers").idTabs(".activePanel"); }); </script> To run the plugin on two different areas: div#requestPool this has it's own tabs and it's own tab content, Also the div.tabs which is another place and has it's own tabs and it's own tabs content. The div.miniTabs and div.switchers are the divs that includes the tabs links (tabs headers) and I putted them in the snippet to change the default selected tab class from .selected to .active and .activePanel Now, what I would love to add is a nice fadeIn and fadeOut effects to the content of my tabs while browsing through them. Thanks Here is the HTML code for one of the tabbed areas: <div id="requestPool"> <!-- The tabs heads --> <div class="miniTabs"> <a href="#today" class="active">Today</a> <!-- First active tab --> <a href="#tomorrow">Tomorrow</a> <a href="#friday">Friday</a> <a href="#saturday">Saturday</a> <a href="#sunday">Sunday</a> <a href="#monday">Monday</a> <a href="#tuesday">Tuesday</a> </div> <!-- The tabs contents (the ones that I want them to fade in and out while browsing through them using the tabs above) --> <div id="today"class="miniTab"></div> <div id="tomorrow"class="miniTab"></div> <div id="friday"class="miniTab"></div> <div id="saturday"class="miniTab"></div> <div id="sunday"class="miniTab"></div> ...etc the week days </div> Thanks very much (again the tabs are working very fine, but without the fade effect which I want to have).

  • Repeat Customers Each Year (Retention)

    - by spazzie
    I've been working on this and I don't think I'm doing it right. |D Our database doesn't keep track of how many customers we retain so we looked for an alternate method. It's outlined in this article. It suggests you have this table to fill in: Year Number of Customers Number of customers Retained in 2009 Percent (%) Retained in 2009 Number of customers Retained in 2010 Percent (%) Retained in 2010 .... 2008 2009 2010 2011 2012 Total The table would go out to 2012 in the headers. I'm just saving space. It tells you to find the total number of customers you had in your starting year. To do this, I used this query since our starting year is 2008: select YEAR(OrderDate) as 'Year', COUNT(distinct(billemail)) as Customers from dbo.tblOrder where OrderDate >= '2008-01-01' and OrderDate <= '2008-12-31' group by YEAR(OrderDate) At the moment we just differentiate our customers by email address. Then you have to search for the same names of customers who purchased again in later years (ours are 2009, 10, 11, and 12). I came up with this. It should find people who purchased in both 2008 and 2009. SELECT YEAR(OrderDate) as 'Year',COUNT(distinct(billemail)) as Customers FROM dbo.tblOrder o with (nolock) WHERE o.BillEmail IN (SELECT DISTINCT o1.BillEmail FROM dbo.tblOrder o1 with (nolock) WHERE o1.OrderDate BETWEEN '2008-1-1' AND '2009-1-1') AND o.BillEmail IN (SELECT DISTINCT o2.BillEmail FROM dbo.tblOrder o2 with (nolock) WHERE o2.OrderDate BETWEEN '2009-1-1' AND '2010-1-1') --AND o.OrderDate BETWEEN '2008-1-1' AND '2013-1-1' AND o.BillEmail NOT LIKE '%@halloweencostumes.com' AND o.BillEmail NOT LIKE '' GROUP BY YEAR(OrderDate) So I'm just finding the customers who purchased in both those years. And then I'm doing an independent query to find those who purchased in 2008 and 2010, then 08 and 11, and then 08 and 12. This one finds 2008 and 2010 purchasers: SELECT YEAR(OrderDate) as 'Year',COUNT(distinct(billemail)) as Customers FROM dbo.tblOrder o with (nolock) WHERE o.BillEmail IN (SELECT DISTINCT o1.BillEmail FROM dbo.tblOrder o1 with (nolock) WHERE o1.OrderDate BETWEEN '2008-1-1' AND '2009-1-1') AND o.BillEmail IN (SELECT DISTINCT o2.BillEmail FROM dbo.tblOrder o2 with (nolock) WHERE o2.OrderDate BETWEEN '2010-1-1' AND '2011-1-1') --AND o.OrderDate BETWEEN '2008-1-1' AND '2013-1-1' AND o.BillEmail NOT LIKE '%@halloweencostumes.com' AND o.BillEmail NOT LIKE '' GROUP BY YEAR(OrderDate) So you see I have a different query for each year comparison. They're all unrelated. So in the end I'm just finding people who bought in 2008 and 2009, and then a potentially different group that bought in 2008 and 2010, and so on. For this to be accurate, do I have to use the same grouping of 2008 buyers each time? So they bought in 2009 and 2010 and 2011, and 2012? This is where I'm worried and not sure how to proceed or even find such data. Any advice would be appreciated! Thanks!

  • Serialize JavaScript's navigator object

    - by kappa
    Hi, I'm creating a page to help diagnose the problem our users are experiencing with our web pages (you know, asking a user "What browser are you using?" usually leads to "Internet"). This page already submits to me all the HTTP headers and now I'm trying to have JavaScript give some more informations, so I thought it would be great to have the user's navigator JavaScript object and I started looking how to serialize it so I can submit it through a form. The problem is I'm not able to serialize the navigator object using any JSON library I know of, everyone returns an empty object (?!), so I decided to write an ad-hoc serializer. You can find the code here: <!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> function serialize (object) { var type = typeof object; if (object === null) { return '"nullValue"'; } if (type == 'string' || type === 'number' || type === 'boolean') { return '"' + object + '"'; } else if (type === 'function') { return '"functionValue"'; } else if (type === 'object') { var output = '{'; for (var item in object) { if (item !== 'enabledPlugin') { output += '"' + item + '":' + serialize(object[item]) + ','; } } return output.replace(/\,$/, '') + '}'; } else if (type === 'undefined') { return '"undefinedError"'; } else { return '"unknownTypeError"'; } }; $(document).ready(function () { $('#navigator').text(serialize(navigator)); }); </script> <style type="text/css"> #navigator { font-family: monospaced; } </style> <title>Serialize</title> </head> <body> <h1>Serialize</h1> <p id="navigator"></p> </body> </html> This code seems to work perfectly in Firefox, Opera, Chrome and Safari but (obviously) doesn't work in Internet Explorer (at least version 8.0), it complains that "Property or method not supported by the object" at line for (var item in object) {. Do you have any hint on how to fix the code or how to reach the goal (serialize the navigator object) by other means?

  • What's causing this background-image to display "incorrectly" in Opera and Firefox?

    - by Sukasa
    I know this is something I'm probably doing wrong, so please don't incinerate me for the thread title. I'm trying to put together a small personal website using HTML 5/CSS3. I've checked with the w3c validator and the site and CSS file fully conform according to the validator (However the validator has a warning attached that it might not be perfect). I'm not sure how to explain it without a picture, so here's a comparison of Chrome/Opera/Firefox: So, you can sorta see how in Chrome the background image is in one non-repeating piece, whereas in Opera/Firefox the image has, oddly, been broken up and placed slightly differently. I'm confident this is due to an error on my part, but I've had no luck at all figuring out why the image is being mangled in Opera and Firefox. Here's the CSS that's relevant to this issue: /* Content Pane */ .content { position: absolute; left: 220px; width: 800px; top: 80px; min-height: 550px; background-color: rgba(8,12,42,0.85); } /* Headers */ .content hgroup { background: url("Header_Flat.png") no-repeat left top; min-height: 38px; padding-left: 28px; text-shadow: 0 0 8px #FFA9FF; color: Black; text-decoration: none; } .content hgroup h1 { display: block; } .content hgroup h3 { display: inline; position: relative; top: -12px; left: 20px; text-shadow: 0 0 6px #AFF9FF; } .content hgroup h4 { display: inline; position: relative; top: -12px; left: 20px; font-size: xx-small; text-shadow: 0 0 6px #AFF9FF; } And the HTML: <hgroup> <h1>New Site!</h1> <h3>Now with Bloom!</h3> <h4> - Posted Tuesday, May 11th 2010</h4> </hgroup> Can anyone see what I'm doing wrong?

  • XSLT 2.0 Header Leaks into Transformed XML

    - by user1303797
    First, a thank you in advance. Second, this is my first post so apologies for any errors or wrongdoings. I am a noob w/ xml and xslt, and can't seem to figure this out. When I transform some xml using xslt 2.0, some of the headers from the xslt leaks into the new xml. It doesn't seem to do it in xslt 1.0 (granted the xslt is a little different). Here is the xml: <?xml version="1.0" encoding="ISO-8859-1" ?> <xml_content> <feed_name>feed</feed_name> <feed_info> <entry_1> <id>1</id> <pub_date>1320814800</pub_date> </entry_1> </feed_info> </xml_content> Here is the xslt: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/TR/xhtml1/strict"> <xsl:output method="xml" indent="yes" /> <xsl:template match="xml_content"> <Records> <xsl:for-each select="feed_info/entry_1"> <Record> <ID><xsl:value-of select="id" /></ID> <PublicationDate><xsl:value-of select='xs:dateTime("1970-01-01T00:00:00") + xs:integer(pub_date) * xs:dayTimeDuration("PT1S")'/></PublicationDate> </Record> </xsl:for-each> </Records> </xsl:template> </xsl:stylesheet> Here is the new xml. Look specifically at the first "Records" element. <?xml version="1.0" encoding="UTF-8"?> <Records xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/TR/xhtml1/strict"> <Record> <ID>1</ID> <PublicationDate>2011-11-09T05:00:00</PublicationDate> </Record> </Records>

  • How SQLite on Android handles long stings?

    - by Levara
    Hi! I'm wondering how Android's implementation of SQLite handles long Strings. Reading from online documentation on sqlite, it said that strings in sqlite are limited to 1 million characters. My strings are definitely smaller. I'm creating a simple RSS application, and after parsing a html document, and extracting text, I'm having problem saving it to a database. I have 2 tables in database, feeds and articles. RSS feeds are correctly saved and retrieved from feeds table, but when saving to the articles table, logcat is saying that it cannot save extracted text to it's column. I don't know if other columns are making problems too, no mention of them in logcat. I'm wondering, since text is from an article on web, are signs like (",',;) creating problems? Is Android automaticaly escaping them, or I have to do that. I'm using a technique for inserting similar to one in notepad tutorial: public long insertArticle(long feedid, String title, String link, String description, String h1, String h2, String h3, String p, String image, long date) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_FEEDID, feedid); initialValues.put(KEY_TITLE, title); initialValues.put(KEY_LINK, link); initialValues.put(KEY_DESCRIPTION, description ); initialValues.put(KEY_H1, h1 ); initialValues.put(KEY_H2, h2); initialValues.put(KEY_H3, h3); initialValues.put(KEY_P, p); initialValues.put(KEY_IMAGE, image); initialValues.put(KEY_DATE, date); return mDb.insert(DATABASE_TABLE_ARTICLES,null, initialValues); } Column P is for extracted text, h1, h2 and h3 are for headers from a page. Logcat reports only column p to be the problem. The table is created with following statement: private static final String DATABASE_CREATE_ARTICLES = "create table articles( _id integer primary key autoincrement, feedid integer, title text, link text not null, description text," + "h1 text, h2 text, h3 text, p text, image text, date integer);"; Thanks!

  • Is it OK to put a standard, pure C header #include directive inside a namespace?

    - by mic_e
    I've got a project with a class log in the global namespace (::log). So, naturally, after #include <cmath>, the compiler gives an error message each time I try to instantiate an object of my log class, because <cmath> pollutes the global namespace with lots of three-letter methods, one of them being the logarithm function log(). So there are three possible solutions, each having their unique ugly side-effects. Move the log class to it's own namespace and always access it with it's fully qualified name. I really want to avoid this because the logger should be as convenient as possible to use. Write a mathwrapper.cpp file which is the only file in the project that includes <cmath>, and makes all the required <cmath> functions available through wrappers in a namespace math. I don't want to use this approach because I have to write a wrapper for every single required math function, and it would add additional call penalty (cancelled out partially by the -flto compiler flag) The solution I'm currently considering: Replace #include <cmath> by namespace math { #include "math.h" } and then calculating the logarithm function via math::log(). I have tried it out and it does, indeed, compile, link and run as expected. It does, however, have multiple downsides: It's (obviously) impossible to use <cmath>, because the <cmath> code accesses the functions by their fully qualified names, and it's deprecated to use in C++. I've got a really, really bad feeling about it, like I'm gonna get attacked and eaten alive by raptors. So my question is: Is there any recommendation/convention/etc that forbid putting include directives in namespaces? Could anything go wrong with diferent C standard library implementations (I use glibc), different compilers (I use g++ 4.7, -std=c++11), linking? Have you ever tried doing this? Are there any alternate ways to banish the math functions from the global namespace? I've found several similar questions on stackoverflow, but most were about including other C++ headers, which obviously is a bad idea, and those that weren't made contradictory statements about linking behaviour for C libraries. Also, would it be beneficial to additionally put the #include <math.h> inside extern "C" {}?

  • nginx proxying websockets, must be missing something

    - by CodeMonkey
    I have a basic chat app written in node.js using express and socket.io; it works fine when connecting directly to node on port 3000 But doesn't work when I try to use nginx v1.4.2 as a proxy. I start off using the connection map map $http_upgrade $connection_upgrade { default upgrade; '' close; } Then add the locations location /socket.io/ { proxy_pass http://node; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header X-Request-Id $txid; proxy_set_header X-Session-Id $uid_set+$uid_got; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; proxy_buffering off; proxy_read_timeout 86400; keepalive_timeout 90; proxy_cache off; access_log /var/log/nginx/webservice.access.log; error_log /var/log/nginx/webservice.error.log; } location /web-service/ { proxy_pass http://node; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header X-Request-Id $txid; proxy_set_header X-Session-Id $uid_set+$uid_got; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; proxy_buffering off; proxy_read_timeout 86400; keepalive_timeout 90; access_log /var/log/nginx/webservice.access.log; error_log /var/log/nginx/webservice.error.log; rewrite /web-service/(.*) /$1 break; proxy_cache off; } These are built up using all of the tips to get it working that I could find. The error log does not show any errors. (except when I stop node to test the error logging is working) When through nginx I do see a websocket connection in the dev tools, with the status of 101; but the frames tab under the resuects is empty. The only differnece I can see in the response headers is a case difference - "upgrade" vs "Upgrade" - through nginx : Connection:upgrade Date:Fri, 08 Nov 2013 11:49:25 GMT Sec-WebSocket-Accept:LGB+iEBb8Ql9zYfqNfuuXzdzjgg= Server:nginx/1.4.2 Upgrade:websocket direct from node Connection:Upgrade Sec-WebSocket-Accept:8nwPpvg+4wKMOyQBEvxWXutd8YY= Upgrade:websocket output from node (when used through nginx) debug - served static content /socket.io.js debug - client authorized info - handshake authorized iaej2VQlsbLFIhachyb1 debug - setting request GET /socket.io/1/websocket/iaej2VQlsbLFIhachyb1 debug - set heartbeat interval for client iaej2VQlsbLFIhachyb1 debug - client authorized for debug - websocket writing 1:: debug - websocket writing 5:::{"name":"message","args":[{"message":"welcome to the chat"}]} debug - clearing poll timeout debug - jsonppolling writing io.j[0]("8::"); debug - set close timeout for client 7My3F4CuvZC0I4Olhybz debug - jsonppolling closed due to exceeded duration debug - clearing poll timeout debug - jsonppolling writing io.j[0]("8::"); debug - set close timeout for client AkCYl0nWNZAHeyUihyb0 debug - jsonppolling closed due to exceeded duration debug - setting request GET /socket.io/1/xhr-polling/iaej2VQlsbLFIhachyb1?t=1383911206158 debug - setting poll timeout debug - discarding transport debug - cleared heartbeat interval for client iaej2VQlsbLFIhachyb1 debug - setting request GET /socket.io/1/jsonp-polling/iaej2VQlsbLFIhachyb1?t=1383911216160&i=0 debug - setting poll timeout debug - discarding transport debug - clearing poll timeout debug - clearing poll timeout debug - jsonppolling writing io.j[0]("8::"); debug - set close timeout for client iaej2VQlsbLFIhachyb1 debug - jsonppolling closed due to exceeded duration debug - setting request GET /socket.io/1/jsonp-polling/iaej2VQlsbLFIhachyb1?t=1383911236429&i=0 debug - setting poll timeout debug - discarding transport debug - cleared close timeout for client iaej2VQlsbLFIhachyb1 when direct to node, the client does not start polling.

I have set this up as per the documentation here: http://docs.puppetlabs.com/guides/scaling_multiple_masters.html I have configured my second puppet master as follows: [main] ... ca = false ca_server = puppet-master1.test.net I am using passenger so I am a bit confused how the virtual-host.conf file should look for my second puppet-master2.test.net. Here is mine (updated as per Shane Maddens answer): LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18/ext/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18 PassengerRuby /usr/bin/ruby Listen 8140 <VirtualHost *:8140> ProxyPassMatch ^/([^/]+/certificate.*)$ https://puppet-master1.test.net:8140/$1 SSLEngine on SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP SSLCertificateFile /var/lib/puppet/ssl/certs/puppet-master2.test.net.pem SSLCertificateKeyFile /var/lib/puppet/ssl/private_keys/puppet-master2.test.net.pem #SSLCertificateChainFile /var/lib/puppet/ssl/ca/ca_crt.pem #SSLCACertificateFile /var/lib/puppet/ssl/ca/ca_crt.pem # If Apache complains about invalid signatures on the CRL, you can try disabling # CRL checking by commenting the next line, but this is not recommended. #SSLCARevocationFile /var/lib/puppet/ssl/ca/ca_crl.pem SSLVerifyClient optional SSLVerifyDepth 1 # The `ExportCertData` option is needed for agent certificate expiration warnings SSLOptions +StdEnvVars +ExportCertData # This header needs to be set if using a loadbalancer or proxy RequestHeader unset X-Forwarded-For RequestHeader set X-SSL-Subject %{SSL_CLIENT_S_DN}e RequestHeader set X-Client-DN %{SSL_CLIENT_S_DN}e RequestHeader set X-Client-Verify %{SSL_CLIENT_VERIFY}e DocumentRoot /etc/puppet/rack/public/ RackBaseURI / <Directory /etc/puppet/rack/> Options None AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> I have commented out the #SSLCertificateChainFile, #SSLCACertificateFile & #SSLCARevocationFile - this is not a CA server so not sure I need this. How would I get passenger to work with these? I would like to use ProxyPassMatch which I have configured as per the documentation. I don't want to specify a ca server in every puppet.conf file. I am getting this error when trying to get create a cert from a puppet client pointing to the second puppet master server (puppet-master2.test.net): [root@puppet-client2 ~]# puppet agent --test Error: Could not request certificate: Could not intern from s: nested asn1 error Exiting; failed to retrieve certificate and waitforcert is disabled On the puppet client I have this [main] server = puppet-master2.test.net What have I missed? -- update Here is a new virtual host file on my secondary puppet master. Is this correct? I have SSL turned off? LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18/ext/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18 PassengerRuby /usr/bin/ruby # you probably want to tune these settings PassengerHighPerformance on PassengerMaxPoolSize 12 PassengerPoolIdleTime 1500 # PassengerMaxRequests 1000 PassengerStatThrottleRate 120 RackAutoDetect Off RailsAutoDetect Off Listen 8140 <VirtualHost *:8140> SSLEngine off ProxyPassMatch ^/([^/]+/certificate.*)$ https://puppet-master1.test.net:8140/$1 # Obtain Authentication Information from Client Request Headers SetEnvIf X-Client-Verify "(.*)" SSL_CLIENT_VERIFY=$1 SetEnvIf X-SSL-Client-DN "(.*)" SSL_CLIENT_S_DN=$1 DocumentRoot /etc/puppet/rack/public/ RackBaseURI / <Directory /etc/puppet/rack/> Options None AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> Cheers, Oli
