  • Generating PDF document using XSLT

    - by Nair
    I have one huge XML document. I have set of XSL representing each node in the XML. These XSL also have java script to generate the dynamic content. It uses images which are in seperate images folder and it uses fonts as well. At present, I have a program which displays all the nodes that can be transformed and user click on one of the node and the program performs XSLT and display the content in HTML format on IE screen. I want to write a program (.Net , C# or any .Net language) which will allow user to do XSLT tranform on all the available notes and create one PDF document. My initial requirement was to display all the document in the IE itself, so I reused the existing code, and foreach node, perform XSLT and then append it to the current HTML with a page break and it worked ok till we hit huge files. So the requirement changed to create one PDF file with all the nodes. I have couple of questions, 1. What is the best way to create PDF file using XSLT transformation? 2. Since the images are relative path, if we generate the XSLT in html and then write it to a output stream will it loose the images? 3. Will the font be preserved in the PDF document? Really appriciate if someone could point me to some good example that I can take and run with it. Thanks a lot.

  • Uninterruptible Windows Process

    - by Nullstr1ng
    Hi Guys, We're starting a new custom project right now from a client and one of the requirements is the process cannot be terminated unless the system is shutting down, restarting, or logging-off. This application monitors the USB interface. We will be using WMI to query the device periodically. The client want's to run the application on Windows XP Operating System and doesn't like installing .NET. So we targeted Visual Basic 6 as our language. My main concern is this application cannot be terminated. Our Project Adviser talks about Anti-virus and yes, some of the anti virus cannot be terminated. I was thinking how to do the same in Visual Basic 6. I know there will be API involved on the project but where should I go? so API is ok with me. I saw some articles that converts the EXE to a SERVICE, create Windows Service in Visual Basic 6, etc. So please .. share your thoughts.

  • Google Calendar like interface

    - by John Virgolino
    I need to write an application that essentially functions like a week-view of a calendar, columns for the days and then rows for appointments. Where the height of the appointment box visually represents time. In my case, I just don't want the time of day as the vertical axis, I just want hours or mins. The Google AJAX approach is very clean and easy to use and would be perfect, I think, but my major knowledge comes in ASP.Net and Windows Forms (.Net). I don't want to reinvent the wheel, but I find my mind is stuck on this problem and that I would have to create an interface from scratch for this. I have checked out the Infragistics product (used it for other projects) and read up a lot on the Google API's including their Ajax toolkit. I haven't done Java, however learning a language is not my issue, it's learning the particulars that will help me reach my goal that I feel will take most of the time. Am I making a mountain out of a mole hill? Is this really a lot easier than I think? This is starting to sound like a Dear Abby post - I'll stop now. Any advice or insight would be great! Thanks all!

  • MySQL FULLTEXT aggravation

    - by southof40
    Hi - I'm having problems with case-sensitivity in MySQL FULLTEXT searches. I've just followed the FULLTEXT example in the MySQL doco at http://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html . I'll post it here for ease of reference ... CREATE TABLE articles ( id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY, title VARCHAR(200), body TEXT, FULLTEXT (title,body) ); INSERT INTO articles (title,body) VALUES ('MySQL Tutorial','DBMS stands for DataBase ...'), ('How To Use MySQL Well','After you went through a ...'), ('Optimizing MySQL','In this tutorial we will show ...'), ('1001 MySQL Tricks','1. Never run mysqld as root. 2. ...'), ('MySQL vs. YourSQL','In the following database comparison ...'), ('MySQL Security','When configured properly, MySQL ...'); SELECT * FROM articles WHERE MATCH (title,body) AGAINST ('database' IN NATURAL LANGUAGE MODE); ... my problem is that the example shows that SELECT returning the first and fifth rows ('..DataBase..' and '..database..') but I only get one row ('database') ! The example doesn't demonstrate what collation the table in the example had but I have ended up with latin1_general_cs on the title and body columns of my example table. My version of MySQL is 5.1.39-log and the connection collation is utf8_unicode_ci . I'd be really grateful is someone could suggest why my experience differs from the example in the manual ! Be grateful for any advice.

  • Yet another Haskell vs. Scala question

    - by Travis Brown
    I've been using Haskell for several months, and I love it—it's gradually become my tool of choice for everything from one-off file renaming scripts to larger XML processing programs. I'm definitely still a beginner, but I'm starting to feel comfortable with the language and the basics of the theory behind it. I'm a lowly graduate student in the humanities, so I'm not under a lot of institutional or administrative pressure to use specific tools for my work. It would be convenient for me in many ways, however, to switch to Scala (or Clojure). Most of the NLP and machine learning libraries that I work with on a daily basis (and that I've written in the past) are Java-based, and the primary project I'm working for uses a Java application server. I've been mostly disappointed by my initial interactions with Scala. Many aspects of the syntax (partial application, for example) still feel clunky to me compared to Haskell, and I miss libraries like Parsec and HXT and QuickCheck. I'm familiar with the advantages of the JVM platform, so practical questions like this one don't really help me. What I'm looking for is a motivational argument for moving to Scala. What does it do (that Haskell doesn't) that's really cool? What makes it fun or challenging or life-changing? Why should I get excited about writing it?

  • Comprehending the Semantic web and it's methods, syntax, vocabularies and languages

    - by DreamCodeR
    Hi. I have just been introduced to the semantic web and it's family of functions but I have a hard time understanding some of it, which I was hoping someone could explain to me. As far as I've understood, RDF can be written in several syntaxes. RDF/XML, Turtle, etc. Now, I understand XML. How it is presented and how it can be parsed. However, some people write in the turtle syntax, but how do they parse that information? I can't seem to find a single library for any language to "extract" the information written in a turtle syntax into another form. The same goes for N3. How can it be used? Executed or else? I seem to be able to understand RDFa. That it is a way to implement RDF into XHTML. For me that is a way to implement RDF into "something". But how can I compare that to turtle, N3, or the like? Thanks in advance.

  • Create xml file to be used in wordpress post import

    - by adedoy
    Alright here is the thing, I have this site that was once wordpress but have been converted into 70+ static pages, the admin is deleted and the whole site is static(which means every page is in index.html), I want to create a script that makes an xml so that I will just have to import it in the new wordpress install. So far, I am able to create an XML but it only imports one post. The data source is the URL of a page and I use jquery $get to filter only to gather the post of a given archive. //html <input type="text" class="full_path"> <input type="button" value="Get Data" class="getdata"> //script $('.getdata').click(function(){ $.get($('.full_path').val(), function(data) { post = $(data).find('div [style*="width:530px;"]'); $('.result').html(post.html()); }); });//get Data Through AJAX I send the cleaned data into a php below that creates the XML: $file = 'newpost.xml'; $post_data = $_REQUEST['post_data']; // Open the file to get existing content $current = file_get_contents($file); // Append a new post to the file $catStr = ''; if(isset($post_data['categories']) && count($post_data['categories']) > 0){ foreach($post_data['categories'] as $category) { $catStr .= '<category domain="category" nicename="'.$category.'"><![CDATA['.$category.']]></category>'; } } $tagStr = ''; if(isset($post_data['tags']) && count($post_data['tags']) > 0){ foreach($post_data['tags'] as $tag) { $tagStr = '<category domain="post_tag" nicename="'.$tag.'"><![CDATA['.$tag.']]></category>'; } } $post_name = str_replace(' ','-',$post_data["title"]); $post_name = str_replace(array('"','/',':','.',',','[',']','“','”'),'',strtolower($post_name)); $post_date = '2011-4-0'.rand(1, 29).''.rand(1, 12).':'.rand(1, 59).':'.rand(1, 59); $pubTime = rand(1, 12).':'.rand(1, 59).':'.rand(1, 59).' +0000'; $post = ' <item> <title>'.$post_data["title"].'</title> <link>'.$post_data["link"].'</link> <pubDate>'.$post_data["date"].'

  • postgres - ERROR: operator does not exist

    - by cino21122
    Again, I have a function that works fine locally, but moving it online yields a big fat error... Taking a cue from a response in which someone had pointed out the number of arguments I was passing wasn't accurate, I double-checked in this situation to be certain that I am passing 5 arguments to the function itself... Query failed: ERROR: operator does not exist: point <@> point HINT: No operator matches the given name and argument type(s). You may need to add explicit type casts. The query is this: BEGIN; SELECT zip_proximity_sum('zc', (SELECT g.lat FROM geocoded g LEFT JOIN masterfile m ON g.recordid = m.id WHERE m.zip = '10050' ORDER BY m.id LIMIT 1), (SELECT g.lon FROM geocoded g LEFT JOIN masterfile m ON g.recordid = m.id WHERE m.zip = '10050' ORDER BY m.id LIMIT 1), (SELECT m.zip FROM geocoded g LEFT JOIN masterfile m ON g.recordid = m.id WHERE m.zip = '10050' ORDER BY m.id LIMIT 1) ,10); The PG function is this: CREATE OR REPLACE FUNCTION zip_proximity_sum(refcursor, numeric, numeric, character, numeric) RETURNS refcursor AS $BODY$ BEGIN OPEN $1 FOR SELECT r.zip, point($2,$3) <@> point(g.lat, g.lon) AS distance FROM geocoded g LEFT JOIN masterfile r ON g.recordid = r.id WHERE (geo_distance( point($2,$3),point(g.lat,g.lon)) < $5) ORDER BY r.zip, distance; RETURN $1; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE COST 100;

  • I want to read program content from command line.

    - by Alexandre Dominos
    I am trying to update a program which was wrotten in 1995 with pascal or c. I am not sure about programming language. Command line program. Now I am coded in C#. And I want to read program command line content. Is it possible? I tried something. But not succesfull. They are: private void aboutToolStripMenuItem_Click(object sender, EventArgs e) { // Redirect the output stream of the child process. p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.FileName = "osl.exe"; p.Start(); logs.AppendText("Timer Started\n"); timer1.Enabled = true; } private void timer1_Tick(object sender, EventArgs e) { // write somethingg and read what is the program doing on command line? // What is the program printint? etc... // I try this code but not enough for mo. // logs.AppendText("d:" + p.StandardOutput.ReadToEnd()+"\n"); } private void p_Exited(object sender, EventArgs e) { timer1.Enabled = false; } i am open to any idea in java,cpp,c,c#.

  • Elegant way of parsing Data files for Simulation

    - by sc_ray
    I am working on this project where I need to read in a lot of data from .dat files and use the data to perform simulations. The data in my .dat file looks as follows: DeviceID InteractingDeviceID InteractionStartTime InteractionEndTime 1 2 1101 1105 1,2 1101 and 1105 are tab delimited and it means Device 1 interacted with Device 2 at 1101 ms and ended the interaction at 1105ms. I have a trace data sets that compile thousands of such interactions and my job is to analyze these interactions. The first step is to parse the file. The language of choice is C++. The approach I was thinking of taking was to read the file, for every line that's read create a Device Object. This Device object will contain the property DeviceId and an array/vector of structs, that will contain a list of all the devices the given DeviceId interacted with over the course of the simulation.The struct will contain the Interacting Device Id, Interaction Start Time and Interaction End Time. I have a two fold question here: Is my approach correct? If I am on the right track, how do I rapidly parse these tab delimited data files and create Device objects without excessive memory overhead using C++? A push in the right direction will be much appreciated. Thanks

  • asp:login form does not submit when you hit enter

    I am having an issues while using the <asp:login> tag. When a user clicks the "login" button, the form will process correctly. However, when the user hits the enter key, the form self submits and does not process the login, whether it was correct information or not. I am using a combination of MasterPages, and Umbraco.

  • Retrieve OpenId FullName from Google

    - by user294711
    I'm using DotNetOpenAuth lib to work with Google(only) OpenId. And I'm retrieving Email without any problem. But I can't get FullName, it is always null. request.AddExtension(new ClaimsRequest { Email = DemandLevel.Require, FullName = DemandLevel.Require }); ClaimsResponse claimsResponse = relyingPartyResponse.GetExtension<ClaimsResponse>(); if (claimsResponse != null) { var email = claimsResponse.Email; var fullName = claimsResponse.FullName; } I googled this problem and found that: Glad you got it working. Google will not give a full name or nickname for their users. They ONLY give email address, and (I think, but perhaps only on a white list) the timezone. It's not a matter of figuring out how to rig your RP so that it works. Google just won't do it yet. – Andrew Arnott Sep 8 at 14:22 stackoverflow.com/questions/1387438/retrieve-openid-user-information-claims-across-providers But it was in Sep 2009, maybe something was changed from that moment... I've found that in http://code.google.com/apis/accounts/docs/OpenID.html: openid.ax.required -- (required) Specifies the attribute being requested. Valid values include: "country", "email", "firstname", "language", "lastname". To request multiple attributes, set this parameter to a comma-delimited list of attributes. So, my question is how can I get FullName (FirstName, LastName) from Google OpenId?

  • Parse usable Street Address, City, State, Zip from a string

    - by Rob Allen
    Problem: I have an address field from an Access database which has been converted to Sql Server 2005. This field has everything all in one field. I need to parse out the individual sections of the address into their appropriate fields in a normalized table. I need to do this for approximately 4,000 records and it needs to be repeatable. Here are the rules for this exercise: 1 - no whining about how this should have been separate fields in the first place, we are often confronted with less than ideal situations and have to make the best of them 2- for this post, use any language you want 3- feel free to play code golf 4 - Assume an address in the US (for now) 5 - assume that the input string will sometimes contain an addressee (the person being addressed) and/or a second street address (i.e. Suite B) 6 - states may be abbreviated 7 - zip code could be standard 5 digit or zip+4 8 - there are typos in some instances UPDATE: In response to the questions posed, standards were not universally followed, I need need to store the individual values, not just geocode and errors means typo (corrected above) Sample Data: A.

  • Python to C# with openSSL requirement

    - by fonix232
    Hey there again! Today I ran into a problem when I was making a new theme creator for chrome. As you may know, Chrome uses a "new" file format, called CRX, to manage it's plugins and themes. It is a basic zip file, but a bit modified: "Cr24" + derkey + signature + zipFile And here comes the problem. There are only two CRX creators, written in Ruby or Python.

  • questions about name mangling in C++

    - by Tim
    I am trying to learn and understand name mangling in C++. Here are some questions: (1) From devx When a global function is overloaded, the generated mangled name for each overloaded version is unique. Name mangling is also applied to variables. Thus, a local variable and a global variable with the same user-given name still get distinct mangled names. Are there other examples that are using name mangling, besides overloading functions and same-name global and local variables ? (2) From Wiki The need arises where the language allows different entities to be named with the same identifier as long as they occupy a different namespace (where a namespace is typically defined by a module, class, or explicit namespace directive). I don't quite understand why name mangling is only applied to the cases when the identifiers belong to different namespaces, since overloading functions can be in the same namespace and same-name global and local variables can also be in the same space. How to understand this? Do variables with same name but in different scopes also use name mangling? (3) Does C have name mangling? If it does not, how can it deal with the case when some global and local variables have the same name? C does not have overloading functions, right? Thanks and regards!

  • how would you like computer science classes to be taught?

    - by aaa
    hello I am a graduate student now, and hopefully someday I will teach. my interests are C++, Python, embedded languages, and scientific computing. Meanwhile I daydream about how I would teach. I was not quite happy with my undergraduate university as I found many computer science classes lacking. so I would like to ask you, if you were a student, how would you like your computer science classes to be taught? I understand it is a very subjective question, but nevertheless I think it's important to know what people want. Some specific points I am interested in: should computer languages be taught explicitly, or should students be required to pick up language on their own? what is better for learning, tests, projects, some sort of take-home exam? how do you think classtime should be used? theory, introduction, explanations, etc.? do you think the group projects are important? how much about computer architecture do you want to learn in computer science class, not necessarily assembler class. should particular operating system/editor be mandated or encouraged? Thanks thank you for your comments. Question has been closed because it is a discussion question rather than Q&A. If you know appropriate website for discussions of such sort with low noise ratio, please let me know.

  • When to use certain optimizations such as -fwhole-program and -fprofile-generate with several shared libraries

    - by James
    Probably a simple answer; I get quite confused with the language used in the GCC documentation for some of these flags! Anyway, I have three libraries and a programme which uses all these three. I compile each of my libraries seperately with individual (potentially) different sets of warning flags. However, I compile all three libraries with the same set of optimisation flags. I then compile my main programme linking in these three libraries with its own set of warning flags and the same optimisation flags used during the libraries' compilation. 1) Do I have to compile the libraries with optimisation flags present or can I just use these flags when compiling the final programme and linking to the libraries? If the latter, will it then optimise all or just some (presumably that which is called) of the code in these libraries? 2) I would like to use -fwhole-program -flto -fuse-linker-plugin and the linker plugin gold. At which stage do I compile with these on ... just the final compilation or do these flags need to be present during the compilation of the libraries? 3) Pretty much the same as 2) however with, -fprofile-generate -fprofile-arcs and -fprofile-use. I understand one first runs a programme with generate, and then with use. However, do I have to compile each of the libraries with generate/use etc. or just the final programme? And if it is just the last programme, when I then compeil with -fprofile-use will it also optimise the libraries functionality? Many thanks, James

  • Javascript problem with location.href.

    - by Patrick
    Hello! I have a textbox and whenever the user presses a key it's checked to see if the user pressed enter. If the enter key is pressed, i want to add all the info in the textbox and transfer the user to a different url. <script language="javascript" type="text/javascript"> function checkEnter(e){ //e is event object passed from function invocation var characterCode; if(e && e.which){ //if which property of event object is supported (NN4) e = e; characterCode = e.which; //character code is contained in NN4's which property } else{ e = event; characterCode = e.keyCode; //character code is contained in IE's keyCode property } if (characterCode == 13) { //if generated character code is equal to ascii 13 (if enter key) var searchLink = '/Search/?Keywords=' + document.getElementById('<%= searchBox.ClientID %>').value; transferUser(searchLink); return false; } else{ return true; } } function transferUser(url) { window.location.href = url; window.location.replace(url); } </script> Search: <input name="ctl00$searchBox" type="text" id="ctl00_searchBox" class="header_line_search_box_textbox" onKeyPress="checkEnter(event);" /> I have tried every possible combination, but nothing happens.

  • How to store an inventory using hashtables?

    - by Harm De Weirdt
    Hello everyone. For an assignment in collego we have to make a script in Perl that allows us to manage an inventory for an e-store. (The example given was Amazon) Users can make orders in a fully text-based environment and the inventory must be updated when an order is completed. Every item in the inventory has 3 to 4 attributes: a product code, a title, a price and for some an amount (MP3's for example do not have this attribute) Since this is my first encounter with Perl, i don't really know how to start. My main problem is how i should "implement" the inventory in the program. One of the functions of the program is searching trough the titles. Another is to make an order, where the user should give a product code. My first idea was a hashtable with the productcode as key. But if i wanted to search in the titles that could be a problem because of this: the hashkey would be something like DVD-123, the information belonging to that key could be "The Green Mask 12" (without the ") where the 12 indicates how many of this DVD are currently in stock. So i'd have to find a way to ignore the 12 in the end. Another solution was to use the title as Hashkey, but that would prove cumbersome too I think. Is there a way to make a hashtable with 2 key's, and when I give only one it returns an array with the other values? (Including the other key and the other information) That way I could use another key depending on what info I need from my inventory. We have to read the default inventory from a txt file looking like this: MP3-72|Lady Gaga - Kiss and Run (Fear of Commitment Monster)|0.99 CD-400|Kings of Leon - Only By The Night|14.50|2 MP3-401|Kings of Leon - Closer|0.85 DVD-144|Live Free or Die Hard|14.99|2 SOFT-864|Windows Vista|49.95 Any help would be appreciated very much :) PS: I am sorry for my bad grammar, English isn't my native language.

  • High memory usage for dummies

    - by zaf
    I've just restarted my firefox web browser again because it started stuttering and slowing down. This happens every other day due to (my understanding) of excessive memory usage. I've noticed it takes 40M when it starts and then, by the time I notice slow down, it goes to 1G and my machine has nothing more to offer unless I close other applications. I'm trying to understand the technical reasons behind why its such a difficult problem to sol ve. Mozilla have a page about high memory usage: http://support.mozilla.com/en-US/kb/High+memory+usage But I'm looking for a slightly more in depth and satisfying explanation. Not super technical but enough to give the issue more respect and please the crowd here. Some questions I'm already pondering (they could be silly so take it easy): When I close all tabs, why doesn't the memory usage go all the way down? Why is there no limits on extensions/themes/plugins memory usage? Why does the memory usage increase if it's left open for long periods of time? Why are memory leaks so difficult to find and fix? App and language agnostic answers also much appreciated.

  • Replacing content with jquery.

    - by BillZ
    I am loading a movie into a overlay. My problem is that when I close the div overlay the movie continues to play. I do not control the code on the move side it is imported via a script tag which then opens in a iframe. I am able to remove the content of the of the div and then the movie stops playing. Then of course when the user opens the div again the movie is gone. My current thinking was that I could simply replace the script tag with one just like it but the outcome of that is that there is nothing there. I have been using jquery. Thanks -- script -- $(document).ready(function() { $("#closeModal2").click(function() { $("#movieContainer").html("<script src='http://www.accelacast.com/programs/launch.js'/>"); }); }); -- html -- <div id="movieContainer"> <script id="movieTag" language='JavaScript' src='http://www.accelacast.com/programs/launch.js'/> </div> On a side note. I tried replacing the src attribute of the script tag with no luck. I was able to replace the src of a image though. Is it not possible to effect the src attribute of script? Thanks

  • Database Functional Programming in Clojure

    - by Ralph
    "It is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail." - Abraham Maslow I need to write a tool to dump a large hierarchical (SQL) database to XML. The hierarchy consists of a Person table with subsidiary Address, Phone, etc. tables. I have to dump thousands of rows, so I would like to do so incrementally and not keep the whole XML file in memory. I would like to isolate non-pure function code to a small portion of the application. I am thinking that this might be a good opportunity to explore FP and concurrency in Clojure. I can also show the benefits of immutable data and multi-core utilization to my skeptical co-workers. I'm not sure how the overall architecture of the application should be. I am thinking that I can use an impure function to retrieve the database rows and return a lazy sequence that can then be processed by a pure function that returns an XML fragment. For each Person row, I can create a Future and have several processed in parallel (the output order does not matter). As each Person is processed, the task will retrieve the appropriate rows from the Address, Phone, etc. tables and generate the nested XML. I can use a a generic function to process most of the tables, relying on database meta-data to get the column information, with special functions for the few tables that need custom processing. These functions could be listed in a map(table name -> function). Am I going about this in the right way? I can easily fall back to doing it in OO using Java, but that would be no fun. BTW, are there any good books on FP patterns or architecture? I have several good books on Clojure, Scala, and F#, but although each covers the language well, none look at the "big picture" of function programming design.
