  • Configuring Hibernate logging using Log4j XML config file?

    - by James McMahon
    I haven't been able to find any documentation on how to configure Hibernate's logging using the XML style configuration file for Log4j. Is this even possible or do I have use a properties style configuration file to control Hibernate's logging? If anyone has any information or links to documentation it would appreciated. EDIT: Just to clarify, I am looking for example of the actual XML syntax to control Hibernate. EDIT2: Here is what I have in my XML config file. <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Threshold" value="info"/> <param name="Target" value="System.out"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d{ABSOLUTE} [%t] %-5p %c{1} - %m%n"/> </layout> </appender> <appender name="rolling-file" class="org.apache.log4j.RollingFileAppender"> <param name="file" value="Program-Name.log"/> <param name="MaxFileSize" value="1000KB"/> <!-- Keep one backup file --> <param name="MaxBackupIndex" value="4"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %l - %m%n"/> </layout> </appender> <root> <priority value ="debug" /> <appender-ref ref="console" /> <appender-ref ref="rolling-file" /> </root> </log4j:configuration> Logging works fine but I am looking for a way to step down and control the hibernate logging in way that separate from my application level logging, as it currently is flooding my logs. I have found examples of using the preference file to do this, I was just wondering how I can do this in a XML file.

  • How to merge an improperly created "branch" that isn't really a branch (wasn't created by an svn cop

    - by MatrixFrog
    I'm working on a team with lots of people who are pretty unfamiliar with the concepts of version control systems, and are just kind of doing whatever seems to work, by trial and error. Someone created a "branch" from the trunk that is not ancestrally related to the trunk. My guess is it went something like this: They created a folder in branches. They checked out all the code from the trunk to somewhere on their desktop. They added all that code to the newly created folder as though it was a bunch of brand new files. So the repository isn't aware that all that code is actually just a copy of the trunk. When I look at the history of that branch in TortoiseSVN, and uncheck the "Stop on copy/rename" box, there is no revision that has the trunk (or any other path) under the "Copy from path" column. Then they made lots of changes on their "branch". Meanwhile, others were making lots of changes on the trunk. We tried to do a merge and of course it doesn't work. Because, the trunk and the fake branch are not ancestrally related. I can see only two ways to resolve this: Go through the logs on the "branch", look at every change that was made, and manually apply each change to the trunk. Go through the logs on the trunk, look at every change that was made between revision 540 (when the "branch" was created) and HEAD, and manually apply each change to the "branch". This involves 7 revisions one way or 11 revisions the other way, so neither one is really that terrible. But is there any way to cause the repository to "realize" that the branch really IS ancestrally related even though it was created incorrectly, so that we can take advantage of the built-in merging functionality in Eclipse/TortoiseSVN? (You may be wondering: Why did your company hire these people and allow them to access the SVN repository without making sure they knew how to use it properly first?! We didn't -- this is a school assignment, which is a collaboration between two different classes -- the ones in the lower class were given a very quick hand-wavey "overview" of SVN which didn't really teach them anything. I've asked everyone in the group to please PLEASE read the svn book, and I'll make sure we (the slightly more experienced half of the team) keep a close eye on the repository to ensure this doesn't happen again.)

  • What is the best algorithm for this problem?

    - by mark
    What is the most efficient algorithm to solve the following problem? Given 6 arrays, D1,D2,D3,D4,D5 and D6 each containing 6 numbers like: D1[0] = number D2[0] = number ...... D6[0] = number D1[1] = another number D2[1] = another number .... ..... .... ...... .... D1[5] = yet another number .... ...... .... Given a second array ST1, containing 1 number: ST1[0] = 6 Given a third array ans, containing 6 numbers: ans[0] = 3, ans[1] = 4, ans[2] = 5, ......ans[5] = 8 Using as index for the arrays D1,D2,D3,D4,D5 and D6, the number that goes from 0, to the number stored in ST1[0] minus one, in this example 6, so from 0 to 6-1, compare each res array against each D array My algorithm so far is: I tried to keep everything unlooped as much as possible. EML := ST1[0] //number contained in ST1[0] EML1 := 0 //start index for the arrays D While EML1 < EML if D1[ELM1] = ans[0] goto two if D2[ELM1] = ans[0] goto two if D3[ELM1] = ans[0] goto two if D4[ELM1] = ans[0] goto two if D5[ELM1] = ans[0] goto two if D6[ELM1] = ans[0] goto two ELM1 = ELM1 + 1 return 0 //bad row of numbers, if while ends two: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[1] goto two if D2[ELM1] = ans[1] goto two if D3[ELM1] = ans[1] goto two if D4[ELM1] = ans[1] goto two if D5[ELM1] = ans[1] goto two if D6[ELM1] = ans[1] goto two ELM1 = ELM1 + 1 return 0 three: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[2] goto two if D2[ELM1] = ans[2] goto two if D3[ELM1] = ans[2] goto two if D4[ELM1] = ans[2] goto two if D5[ELM1] = ans[2] goto two if D6[ELM1] = ans[2] goto two ELM1 = ELM1 + 1 return 0 four: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[3] goto two if D2[ELM1] = ans[3] goto two if D3[ELM1] = ans[3] goto two if D4[ELM1] = ans[3] goto two if D5[ELM1] = ans[3] goto two if D6[ELM1] = ans[3] goto two ELM1 = ELM1 + 1 return 0 five: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[4] goto two if D2[ELM1] = ans[4] goto two if D3[ELM1] = ans[4] goto two if D4[ELM1] = ans[4] goto two if D5[ELM1] = ans[4] goto two if D6[ELM1] = ans[4] goto two ELM1 = ELM1 + 1 return 0 six: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[0] return 1 //good row of numbers if D2[ELM1] = ans[0] return 1 if D3[ELM1] = ans[0] return 1 if D4[ELM1] = ans[0] return 1 if D5[ELM1] = ans[0] return 1 if D6[ELM1] = ans[0] return 1 ELM1 = ELM1 + 1 return 0 As language of choice, it would be pure c

  • Default Database Collations PenTesting Env

    - by dominicdinada
    I am using Ubuntu 9.10 with XAMPP ( Lampp "MYSQL 5.1.45 PHPMYADMIN 3.3.1 PHP 5.3.2 ) What my problem is, is that I set up my testing env to debug my scripts locally and when I did so there arose a problem. This problem is that I used firefox's addon SQLinject ME to test for weakness' and upon doing so it caused mysql to change the default local collations; character sets dir /opt/lampp/share/mysql/charsets/ collation connection latin1_general_ci (Global value) latin1_swedish_ci collation database latin1_swedish_ci collation server latin1_swedish_ci I have searched for quite sometime in regards to a solution to this problem and have come up with searching for the db.opt file which stores this information without success. Upon not finding a solution I removed lampp with the "sudo rm -fR /opt" command and reinstall and the problem still persists. I have tried to change the collations manually and still come up with the database displaying latin1_swedish_ci as the default language. Why is this a problem?? Why is it a problem with mysql? Because the application I am testing and debugging locally is built on the CodeIgnitor with Smarty framework and since this combination of framework is built to detect the LOCALES, Rather what the database defaults are I keep getting errors saying no language file for swedish...... Of course I could get the swedish language file to work around this problem but I do not feel the need to make this work around a perminant solution as with time when I move on to projects I will run into simular problems every time that A; When importing database files, backups etc it will default to import such databases as the locale swedish. B; As time passes on I might completly forget of this error and will be back to square one. I have found this code in searches for a fix,which seems to alter the tables to a desired Collaion; $value) { mysql_query("ALTER TABLE $value COLLATE latin1_general_ci"); }} echo "The collation of your database has been successfully changed!"; ? Which is handy to switch collations in One Schema at a time however this is not a fix when a framework doesnt care that the said database is in one langugae. It tests for the Default of the entire server. Someone with any knowledge of a purge or fix to this I would greatly appricate the help. One more final note is that when I was testing I only figured to back up the applications DataBase and not the entire Schema of the install. No matter if I uninstall or reinstall the database still seems to carry these problems.

  • Simple form validation. Object-oriented.

    - by kalininew
    Problem statement: It is necessary for me to write a code, whether which before form sending will check all necessary fields are filled. If not all fields are filled, it is necessary to allocate with their red colour and not to send the form. Now the code exists in such kind: function formsubmit(formName, reqFieldArr){ var curForm = new formObj(formName, reqFieldArr); if(curForm.valid) curForm.send(); else curForm.paint(); } function formObj(formName, reqFieldArr){ var filledCount = 0; var fieldArr = new Array(); for(i=reqFieldArr.length-1; i>=0; i--){ fieldArr[i] = new fieldObj(formName, reqFieldArr[i]); if(fieldArr[i].filled == true) filledCount++; } if(filledCount == fieldArr.length) this.valid = true; else this.valid = false; this.paint = function(){ for(i=fieldArr.length-1; i>=0; i--){ if(fieldArr[i].filled == false) fieldArr[i].paintInRed(); else fieldArr[i].unPaintInRed(); } } this.send = function(){ document.forms[formName].submit(); } } function fieldObj(formName, fName){ var curField = document.forms[formName].elements[fName]; if(curField.value != '') this.filled = true; else this.filled = false; this.paintInRed = function(){ curField.addClassName('red'); } this.unPaintInRed = function(){ curField.removeClassName('red'); } } Function is caused in such a way: <input type="button" onClick="formsubmit('orderform', ['name', 'post', 'payer', 'recipient', 'good'])" value="send" /> Now the code works. But I would like to add "dynamism" in it. That it is necessary for me: to keep an initial code essentially, to add listening form fields (only necessary for filling). For example, when the field is allocated by red colour and the user starts it to fill, it should become white. As a matter of fact I need to add listening of events: onChange, blur for the blank fields of the form. As it to make within the limits of an initial code. If all my code - full nonsense, let me know about it. As to me it to change using object-oriented the approach.

  • Simple database design and LINQ

    - by Anders Svensson
    I have very little experience designing databases, and now I want to create a very simple database that does the same thing I have previously had in xml. Here's the xml: <services> <service type="writing"> <small>125</small> <medium>100</medium> <large>60</large> <xlarge>30</xlarge> </service> <service type="analysis"> <small>56</small> <medium>104</medium> <large>200</large> <xlarge>250</xlarge> </service> </services> Now, I wanted to create the same thing in a SQL database, and started doing this ( hope this formats ok, but you'll get the gist, four columns and two rows): > ServiceType Small Medium Large > > Writing 125 100 60 > > Analysis 56 104 200 This didn't work too well, since I then wanted to use LINQ to select, say, the Large value for Writing (60). But I couldn't use LINQ for this (as far as I know) and use a variable for the size (see parameters in the method below). I could only do that if I had a column like "Size" where Small, Medium, and Large would be the values. But that doesn't feel right either, because then I would get several rows with ServiceType = Writing (3 in this case, one for each size), and the same for Analysis. And if I were to add more servicetypes I would have to do the same. Simply repetitive... Is there any smart way to do this using relationships or something? Using the second design above (although not good), I could use the following LINQ to select a value with parameters sent to the method: protected int GetHourRateDB(string serviceType, Size size) { CalculatorLinqDataContext context = new CalculatorLinqDataContext(); var data = (from calculatorData in context.CalculatorDatas where calculatorData.Service == serviceType && calculatorData.Size == size.ToString() select calculatorData).Single(); return data.Hours; } But if there is another better design, could you please also describe how to do the same selection using LINQ with that design? Please keep in mind that I am a rookie at database design, so please be as explicit and pedagogical as possible :-) Thanks! Anders

  • 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.

  • How to show percentage of 'memory used' in a win32 process?

    - by pj4533
    I know that memory usage is a very complex issue on Windows. I am trying to write a UI control for a large application that shows a 'percentage of memory used' number, in order to give the user an indication that it may be time to clear up some memory, or more likely restart the application. One implementation used ullAvailVirtual from MEMORYSTATUSEX as a base, then used HeapWalk() to walk the process heap looking for additional free memory. The HeapWalk() step was needed because we noticed that after a while of running the memory allocated and freed by the heap was never returned and reported by the ullAvailVirtual number. After hours of intensive working, the ullAvailVirtual number no longer would accurately report the amount of memory available. However, this method proved not ideal, due to occasional odd errors that HeapWalk() would return, even when the process heap was not corrupted. Further, since this is a UI control, the heap walking code was executing every 5-10 seconds. I tried contacting Microsoft about why HeapWalk() was failing, escalated a case via MSDN, but never got an answer other than "you probably shouldn't do that". So, as a second implementation, I used PagefileUsage from PROCESS_MEMORY_COUNTERS as a base. Then I used VirtualQueryEx to walk the virtual address space adding up all regions that weren't MEM_FREE and returned a value for GetMappedFileNameA(). My thinking was that the PageFileUsage was essentially 'private bytes' so if I added to that value the total size of the DLLs my process was using, it would be a good approximation of the amount of memory my process was using. This second method seems to (sorta) work, at least it doesn't cause crashes like the heap walker method. However, when both methods are enabled, the values are not the same. So one of the methods is wrong. So, StackOverflow world...how would you implement this? which method is more promising, or do you have a third, better method? should I go back to the original method, and further debug the odd errors? should I stay away from walking the heap every 5-10 seconds? Keep in mind the whole point is to indicate to the user that it is getting 'dangerous', and they should either free up memory or restart the application. Perhaps a 'percentage used' isn't the best solution to this problem? What is? Another idea I had was a color based system (red, yellow, green, which I could base on more factors than just a single number)

  • 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 :)

  • Silverlight with MVVM Inheritance: ModelView and View matching the Model

    - by moonground.de
    Hello Stackoverflowers! :) Today I have a special question on Silverlight (4 RC) MVVM and inheritance concepts and looking for a best practice solution... I think that i understand the basic idea and concepts behind MVVM. My Model doesn't know anything about the ViewModel as the ViewModel itself doesn't know about the View. The ViewModel knows the Model and the Views know the ViewModels. Imagine the following basic (example) scenario (I'm trying to keep anything short and simple): My Model contains a ProductBase class with a few basic properties, a SimpleProduct : ProductBase adding a few more Properties and ExtendedProduct : ProductBase adding another properties. According to this Model I have several ViewModels, most essential SimpleProductViewModel : ViewModelBase and ExtendedProductViewModel : ViewModelBase. Last but not least, according Views SimpleProductView and ExtendedProductView. In future, I might add many product types (and matching Views + VMs). 1. How do i know which ViewModel to create when receiving a Model collection? After calling my data provider method, it will finally end up having a List<ProductBase>. It containts, for example, one SimpleProduct and two ExtendedProducts. How can I transform the results to an ObservableCollection<ViewModelBase> having the proper ViewModel types (one SimpleProductViewModel and two ExtendedProductViewModels) in it? I might check for Model type and construct the ViewModel accordingly, i.e. foreach(ProductBase currentProductBase in resultList) if (currentProductBase is SimpleProduct) viewModels.Add( new SimpleProductViewModel((SimpleProduct)currentProductBase)); else if (currentProductBase is ExtendedProduct) viewModels.Add( new ExtendedProductViewModels((ExtendedProduct)currentProductBase)); ... } ...but I consider this very bad practice as this code doesn't follow the object oriented design. The other way round, providing abstract Factory methods would reduce the code to: foreach(ProductBase currentProductBase in resultList) viewModels.Add(currentProductBase.CreateViewModel()) and would be perfectly extensible but since the Model doesn't know the ViewModels, that's not possible. I might bring interfaces into game here, but I haven't seen such approach proven yet. 2. How do i know which View to display when selecting a ViewModel? This is pretty the same problem, but on a higher level. Ended up finally having the desired ObservableCollection<ViewModelBase> collection would require the main view to choose a matching View for the ViewModel. In WPF, there is a DataTemplate concept which can supply a View upon a defined DataType. Unfortunately, this doesn't work in Silverlight and the only replacement I've found was the ResourceSelector of the SLExtensions toolkit which is buggy and not satisfying. Beside that, all problems from Question 1 apply as well. Do you have some hints or even a solution for the problems I describe, which you hopefully can understand from my explanation? Thank you in advance! Thomas

  • How to work with file and streams in php,case: if we open file in Class A and pass open stream to Cl

    - by Rachel
    I have two class, one is Business Logic Class{BLO} and the other one is Data Access Class{DAO} and I have dependency in my BLO class to my Dao class. Basically am opening a csv file to write into it in my BLO class using inside its constructor as I am creating an object of BLO and passing in file from command prompt: Code: $this->fin = fopen($file,'w+') or die('Cannot open file'); Now inside BLO I have one function notifiy, which call has dependency to DAO class and call getCurrentDBSnapshot function from the Dao and passes the open stream so that data gets populated into the stream. Code: Blo Class Constructor: public function __construct($file) { //Open Unica File for parsing. $this->fin = fopen($file,'w+') or die('Cannot open file'); // Initialize the Repository DAO. $this->dao = new Dao('REPO'); } Blo Class method that interacts with Dao Method and call getCurrentDBSnapshot. public function notifiy() { $data = $this->fin; var_dump($data); //resource(9) of type (stream) $outputFile=$this->dao->getCurrentDBSnapshot($data); // So basically am passing in $data which is resource((9) of type (stream) } Dao function: getCurrentDBSnapshot which get current state of Database table. public function getCurrentDBSnapshot($data) { $query = "SELECT * FROM myTable"; //Basically just preparing the query. $stmt = $this->connection->prepare($query); // Execute the statement $stmt->execute(); $header = array(); while ($row=$stmt->fetch(PDO::FETCH_ASSOC)) { if(empty($header)) { // Get the header values from table(columnnames) $header = array_keys($row); // Populate csv file with header information from the mytable fputcsv($data, $header); } // Export every row to a file fputcsv($data, $row); } var_dump($data);//resource(9) of type (stream) return $data; } So basically in am getting back resource(9) of type (stream) from getCurrentDBSnapshot and am storing that stream into $outputFile in Blo class method notify. Now I want to close the file which I opened for writing and so it should be fclose of $outputFile or $data, because in both the cases it gives me: var_dump(fclose($outputFile)) as bool(false) var_dump(fclose($data)) as bool(false) and var_dump($outputFile) as resource(9) of type (Unknown) var_dump($data) as resource(9) of type (Unknown) My question is that if I open file using fopen in class A and if I call class B method from Class A method and pass an open stream, in our case $data, than Class B would perform some work and return back and open stream and so How can I close that open stream in Class A's method or it is ok to keep that stream open and not use fclose ? Would appreciate inputs as am not very sure as how this can be implemented.

  • 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!

  • Reliable and fast way to convert a zillion ODT files in PDF?

    - by Marco Mariani
    I need to pre-produce a million or two PDF files from a simple template (a few pages and tables) with embedded fonts. Usually, I would stay low level in a case like this, and compose everything with a library like ReportLab, but I joined late in the project. Currently, I have a template.odt and use markers in the content.xml files to fill with data from a DB. I can smoothly create the ODT files, they always look rigth. For the ODT to PDF conversion, I'm using openoffice in server mode (and PyODConverter w/ named pipe), but it's not very reliable: in a batch of documents, there is eventually a point after which all the processed files are converted into garbage (wrong fonts and letters sprawled all over the page). Problem is not predictably reproducible (does not depend on the data), happens in OOo 2.3 and 3.2, in Ubuntu, XP, Server 2003 and Windows 7. My Heisenbug detector is ticking. I tried to reduce the size of batches and restarting OOo after each one; still, a small percentage of the documents are messed up. Of course I'll write about this on the Ooo mailing lists, but in the meanwhile, I have a delivery and lost too much time already. Where do I go? Completely avoid the ODT format and go for another template system. Suggestions? Anything that takes a few seconds to run is way too slow. OOo takes around a second and it sums to 15 days of processing time. I had to write a program for clustering the jobs over several clients. Keep the format but go for another tool/program for the conversion. Which one? There are many apps in the shareware or commercial repositories for windows, but trying each one is a daunting task. Some are too slow, some cannot be run in batch without buying it first, some cannot work from command line, etc. Open source tools tend not to reinvent the wheel and often depend on openoffice. Converting to an intermediate .DOC format could help to avoid the OOo bug, but it would double the processing time and complicate a task that is already too hairy. Try to produce the PDFs twice and compare them, discarding the whole batch if there's something wrong. Although the documents look equal, I know of no way to compare the binary content. Restart OOo after processing each document. it would take a lot more time to produce them it would lower the percentage of the wrong files, and make it very hard to identify them. Go for ReportLab and recreate the pages programmatically. This is the approach I'm going to try in a few minutes. Learn to properly format bulleted lists Thanks a lot.

  • Segmenting a double array of labels

    - by Ami
    The Problem: I have a large double array populated with various labels. Each element (cell) in the double array contains a set of labels and some elements in the double array may be empty. I need an algorithm to cluster elements in the double array into discrete segments. A segment is defined as a set of pixels that are adjacent within the double array and one label that all those pixels in the segment have in common. (Diagonal adjacency doesn't count and I'm not clustering empty cells). |-------|-------|------| | Jane | Joe | | | Jack | Jane | | |-------|-------|------| | Jane | Jane | | | | Joe | | |-------|-------|------| | | Jack | Jane | | | Joe | | |-------|-------|------| In the above arrangement of labels distributed over nine elements, the largest cluster is the “Jane” cluster occupying the four upper left cells. What I've Considered: I've considered iterating through every label of every cell in the double array and testing to see if the cell-label combination under inspection can be associated with a preexisting segment. If the element under inspection cannot be associated with a preexisting segment it becomes the first member of a new segment. If the label/cell combination can be associated with a preexisting segment it associates. Of course, to make this method reasonable I'd have to implement an elaborate hashing system. I'd have to keep track of all the cell-label combinations that stand adjacent to preexisting segments and are in the path of the incrementing indices that are iterating through the double array. This hash method would avoid having to iterate through every pixel in every preexisting segment to find an adjacency. Why I Don't Like it: As is, the above algorithm doesn't take into consideration the case where an element in the double array can be associated with two unique segments, one in the horizontal direction and one in the vertical direction. To handle these cases properly, I would need to implement a test for this specific case and then implement a method that will both associate the element under inspection with a segment and then concatenate the two adjacent identical segments. On the whole, this method and the intricate hashing system that it would require feels very inelegant. Additionally, I really only care about finding the large segments in the double array and I'm much more concerned with the speed of this algorithm than with the accuracy of the segmentation, so I'm looking for a better way. I assume there is some stochastic method for doing this that I haven't thought of. Any suggestions?

  • Auto showing tips and closing popup when lost focus

    - by darkwindkey
    I have two elements: a TextBox, and a Popup, where the popup contains a tree view to show some tips according to text of TextBox. When the textBox got the KeyDown Event, the KeyDown directly executes pup.IsOpen=true to show the popup tips. However, I also want to show the popup tips when the mouse on clicking the TextBox, and auto closing the popups when the mouse click on any place (besides the TextBox and the TreeView in Popup). I have tried some cases but do not works fine. Case1: Add pup.IsOpen=true; in TextBox.PreviewMouseUp, the popup will stay opening, even if I click any other place in the window. Case2: Add pup.IsOpen=true in TextBox.PreviewMouseDown, the popup tips only shows on keep clicking the Mouse. Case3: Using CheckBox with Binding IsChecked to Popup.IsOpen works fine. but the tips is listed according to the content of the TextBox, therefore the checkbox is not editable for user... Here is my code now: <Window x:Class="popUpTesting.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <TextBox Name="SearchBox" HorizontalAlignment="Center" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Center" KeyDown="SearchBox_KeyDown" PreviewMouseUp="SearchBox_PreviewMouseUp" /> <Popup Placement="Bottom" AllowsTransparency="True" PopupAnimation="Fade" StaysOpen="false" x:Name="pup" PlacementTarget="{Binding ElementName=SearchBox}" IsOpen="False" > <Grid> <TreeView HorizontalAlignment="Left" Height="200" VerticalAlignment="Top" Width="200"> <TreeViewItem Header="A"> <TreeViewItem Header="A1"/> </TreeViewItem> <TreeViewItem Header="B"></TreeViewItem> <TreeViewItem Header="C"></TreeViewItem> <TreeViewItem Header="D"></TreeViewItem> </TreeView> </Grid> </Popup> </Grid> </Window> and the event functions: private void SearchBox_KeyDown(object sender, KeyEventArgs e) { pup.IsOpen = true; } private void SearchBox_PreviewMouseUp(object sender, MouseButtonEventArgs e) { pup.IsOpen = true; }

  • .NET: Avoidance of custom exceptions by utilising existing types, but which?

    - by Mr. Disappointment
    Consider the following code (ASP.NET/C#): private void Application_Start(object sender, EventArgs e) { if (!SetupHelper.SetUp()) { throw new ShitHitFanException(); } } I've never been too hesitant to simply roll my own exception type, basically because I have found (bad practice, or not) that mostly a reasonable descriptive type name gives us enough as developers to go by in order to know what happened and why something might have happened. Sometimes the existing .NET exception types even accommodate these needs - regardless of the message. In this particular scenario, for demonstration purposes only, the application should die a horrible, disgraceful death should SetUp not complete properly (as dictated by its return value), but I can't find an already existing exception type in .NET which would seem to suffice; though, I'm sure one will be there and I simply don't know about it. Brad Abrams posted this article that lists some of the available exception types. I say some because the article is from 2005, and, although I try to keep up to date, it's a more than plausible assumption that more have been added to future framework versions that I am still unaware of. Of course, Visual Studio gives you a nicely formatted, scrollable list of exceptions via Intellisense - but even on analysing those, I find none which would seem to suffice for this situation... ApplicationException: ...when a non-fatal application error occurs The name seems reasonable, but the error is very definitely fatal - the app is dead. ExecutionEngineException: ...when there is an internal error in the execution engine of the CLR Again, sounds reasonable, superficially; but this has a very definite purpose and to help me out here certainly isn't it. HttpApplicationException: ...when there is an error processing an HTTP request Well, we're running an ASP.NET application! But we're also just pulling at straws here. InvalidOperationException: ...when a call is invalid for the current state of an instance This isn't right but I'm adding it to the list of 'possible should you put a gun to my head, yes'. OperationCanceledException: ...upon cancellation of an operation the thread was executing Maybe I wouldn't feel so bad using this one, but I'd still be hijacking the damn thing with little right. You might even ask why on earth I would want to raise an exception here but the idea is to find out that if I were to do so then do you know of an appropriate exception for such a scenario? And basically, to what extent can we piggy-back on .NET while keeping in line with rationality?

  • Is this scatter-brained workflow realizable in Git?

    - by Luke Maurer
    This is what I'd like my workflow to look like at a conceptual level: I hack on my new feature for a while I notice a typo in a comment I change it Since the typo is completely unrelated to anything else, I put that change in a pile of comment fixes I keep working on the code I realize I need to flesh out a few utility functions I do so I put that change in its own pile Steps 2, 3, and 4 each repeat throughout the day I finish the new feature and put the changes for that feature in a pile I push nice patches upstream: One with the new feature, a few for the other tweaks, and one with a bunch of comment fixes if enough have accumulated Since I'm both lazy and a perfectionist, I want to be able to do some things out of order: I might correct a typo but forget to put it in the comment fix pile; when I prepare the upstream patches (I'm using git-svn, so I need to be pretty deliberate about these), I'll then pull out the comment fixes at that point. I might forget to separate things altogether until the very end. But I might /also/ have committed some of the piles along the way (sorry, the metaphor is breaking down …). This is all rather like just using Eclipse changesets with SVN, only I can have different changes to the same file in different piles (having to disentangle changes into different commits is what motivated me to move to git-svn, in fact …), and with Git I can have my full discombobulated change history, experimental branches and all, but still make a nice, neat patch. I've just recently started with Git after having wanted to for a good while, and I'm quite happy so far. The biggest way in which the above workflow doesn't really map into Git, though, is that a “bin” can't really be just a local branch, since the working tree only ever reflects the state of a single branch. Or maybe the Git index is a “pile,” and what I want is to have more than one somehow (effectively). I can think of a few ways to approximate what I want (maybe creative use of stash? Intricate stash-checkout-merge dances?), but my grasp on Git isn't solid enough to be sure of how best to put all the pieces together. It's said that Git is more a toolkit than a VCS, so I guess the question comes down to: How do I build this thing with these tools?

  • Mootools Accordion nonfunctional in Opera

    - by nona
    While working as expected in all other browsers, opera refuses to tween the height of content. oddly enough, as i sat annoyed rapidly clicking it over and over again, if it's closed, and you select some text, and keep clicking the same spot long enough, sometimes it pops open. lol. seriously. ahh, it seems to sometimes open the first time clicked after the page is loaded. wth? the javascript: window.addEvent('domready', function(){ var content_height = [];i=0; $$( '.bio_accordion' ).each(function(item){ i++; content_height.push(item.getElement('.moreInfo').offsetHeight); var thisSlider = new Fx.Slide( item.getElement( '.moreInfo' ), { mode: 'horizontal' } ); thisSlider.hide(); item.getElement('.moreInfo').set('tween').tween('height', '0px'); var morph = new Fx.Morph(item.getElement( '.divToggle' )); var selected = 0; item.getElement( '.divToggle' ).addEvents({ 'mouseenter': function(){ if(!selected) this.morph('.div_highlight'); }, 'mouseleave': function(){ if(!selected) { this.morph('.divToggle'); } }, 'click': function(){ if (!selected){ if (this.getElement('.symbol').innerHTML == '+') this.getElement('.symbol').innerHTML = '-'; else this.getElement('.symbol').innerHTML = '+'; item.getElement('.moreInfo').set('tween', { duration: 1500, transition: Fx.Transitions.Bounce.easeOut }).tween('height', content_height[i]); selected = 1; thisSlider.slideIn(); } else{ if (this.getElement('.symbol').innerHTML == '+') this.getElement('.symbol').innerHTML = '-'; else this.getElement('.symbol').innerHTML = '+'; thisSlider.slideOut(); item.getElement('.moreInfo').set('tween', { duration: 1000, transition: Fx.Transitions.Bounce.easeOut }).tween('height', '0px'); selected = 0; } } }); } ); }); the html: <div class="bio_accordion"> <div class="divToggle">test<span class="symbol">-</span></div> <div class="moreInfo" style="margin-left:10px;"> aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf </div> </div> the css: .bio_accordion { padding:0px; margin:0px; } .divToggle { cursor: pointer; color: #ffffff; background-color:#1089b5; padding: 8px; } .div_highlight { padding-left:30px; padding-right:30px; background-color:#096687; } .moreInfo { padding: 2px; padding-top:15px; padding-bottom:15px; overflow: hidden; } .symbol { float:right; }

  • iPhone OS: KVO: Why is my Observer only getting notified at applicationDidfinishLaunching

    - by nickthedude
    I am basically trying to implement an achievement tracking setup in my app. I have a managedObjectModel class called StatTracker to keep track of all sorts of stats and I want my Achievement tracking class to be notified when those stats change so I can check them against a value and see if the user has earned an achievement. I've tried to impliment KVO and I think I'm pretty close to making it happen but the problem I'm running into is this: So in the appDelegate i have an Ivar for my Achievement tracker class, I attach it as an observer to a property value of my statTracker core data entity in the applicationDidFinishLaunching method. I know its making the connection because I've been able to trigger a UIAlert in my AchievementTracker instance, and I've put several log statements that should be triggered whenever the value on the StatTracker's property changes. the log statement appears only once at the application launch. I'm wondering if I'm missing something in the whole object lifecycle scheme of things, I just don't understand why the observer stops getting notified of changes after the applicationDidFinishLaunching method has run. Does it have something to do with the scope of the AchievementTracker reference or more likely the reference to my core data StatTracker is going away once that method finishes up. I guess I'm not sure the right place to place these if that is the case. Would love some help. Here is the code where I add the observer in my appDidFinishLaunching method: [[CoreDataSingleton sharedCoreDataSingleton] incrementStatTrackerStat:@"timesLaunched"]; achievementsObserver = [[AchievementTracker alloc] init]; StatTracker *object = nil; object = [[[CoreDataSingleton sharedCoreDataSingleton] getStatTracker] objectAtIndex:0]; NSLog(@"%@",[object description]); [[CoreDataSingleton sharedCoreDataSingleton] addObserver:achievementsObserver toStat:@"refreshCount"]; here is the code in my core data singleton: -(void) addObserver:(id)observer toStat:(NSString *) statToObserve { NSLog(@"observer added"); NSArray *array = [[NSArray alloc] init]; array = [self getStatTracker]; [[array objectAtIndex:0] addObserver:observer forKeyPath:statToObserve options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld context:NULL]; } and my AchievementTracker: - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { NSLog(@"achievemnt hit"); //NSLog("%@", [change description]); if ([keyPath isEqual:@"refreshCount"] && ((NSInteger)[change valueForKey:@"NSKeyValueObservingOptionOld"] == 60) ) { NSLog(@"achievemnt hit inside"); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"title" message:@"achievement unlocked" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:nil]; [alert show]; } }

  • Zend_Auth / Zend_Session error and storing objects in Auth Storage

    - by Martin
    Hi All, I have been having a bit of a problem with Zend_Auth and keep getting an error within my Acl. Within my Login Controller I setup my Zend_Auth storage as follows $auth = Zend_Auth::getInstance(); $result = $auth->authenticate($adapter); if ($result->isValid()) { $userId = $adapter->getResultRowObject(array('user_id'), null)->user_id; $user = new User_Model_User; $users = new User_Model_UserMapper; $users->find($userId, $user); $auth->getStorage()->write( $user ); } This seems to work well and I am able to use the object stored in the Zend_Auth storage within View Helpers without any problems. The problem that I seem to be having is when I try to use this within my Acl, below is a snippet from my Acl, as soon as it gets to the if($auth->hasIdentity()) { line I get the exception detailed further down. The $user->getUserLevel() is a methord within the User Model that allows me to convert the user_level_id that is stored in the database to a meaning full name. I am assuming that the auto loader sees these kind of methords and tries to load all the classes that would be required. When looking at the exception it appears to be struggling to find the class as it is stored in a module, I have the Auto Loader Name Space setup in my application.ini. Could anyone help with resolving this? class App_Controller_Plugin_Acl extends Zend_Controller_Plugin_Abstract { protected $_roleName; public function __construct() { $auth = Zend_Auth::getInstance(); if($auth->hasIdentity()) { $user = $auth->getIdentity(); $this->_roleName = strtolower($user->getUserLevel()); } else { $this->_roleName = 'guest'; } } } Fatal error: Uncaught exception 'Zend_Session_Exception' with message 'Zend_Session::start() - \Web\library\Zend\Loader.php(Line:146): Error #2 include_once() [&lt;a href='function.include'&gt;function.include&lt;/a&gt;]: Failed opening 'Menu\Model\UserLevel.php' for inclusion (include_path='\Web\application/../library;\Web\library;.;C:\php5\pear') Array' in \Web\library\Zend\Session.php:493 Stack trace: #0 \Web\library\Zend\Session\Namespace.php(143): Zend_Session::start(true) #1 \Web\library\Zend\Auth\Storage\Session.php(87): Zend_Session_Namespace-&gt;__construct('Zend_Auth') #2 \Web\library\Zend\Auth.php(91): Zend_Auth_Storage_Session-&gt;__construct() #3 \Web\library\Zend\A in \Web\library\Zend\Session.php on line 493 Thanks, Martin

  • Various GPS Android Functionality Questions..

    - by Tyler
    Hello - I have a few questions (so far) with the the LocationManager on Android and GPS in general.. Feel free to answer any number of the questions below, and I appreciate your help in advance! (I noticed this stuff doesn't appear to be documented very well, so hopefully these questions will help others out too!) 1) I am using the following code, but I think there may be extra fluff in here that I do not need. Can you tell me if I can delete any of this? LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); LocationListener locationListener = new MyLocationListener(); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener); LocationProvider locationProvider = lm.getProvider("gps"); Location currentLocation = lm.getLastKnownLocation(locationProvider.getName()); 2) Is there a way to hold off on the last step (accessing "getLastKnownLocation" until after I am sure I have a GPS lock? What happens if this is called and GPS is still looking for signal? 3) MOST importantly, I want to ensure I have a GPS lock before I proceed to my next method, so is there a way to check to see if GPS is locked on and getLastKnownLocation is up to date? 4) Is there a way to 'shut down' the GPS listener once it does receive a lock and getLastKnownLocation is updated? I don't see a need to keep this running for my application once I have obtained a lock.. 5) Can you please confirm my assumption that "getLastKnownLocation" is updated frequently as the receiver moves? 6) In my code, I also have a class called "MyLocationListener" (code below) that I honestly just took from another example.. Is this actually needed? I assume this updates my location manager whenever the location changes, but it sure doesn't appear that there is much to the class itself! private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { if (loc != null) { //Toast.makeText(getBaseContext(), "Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude(), Toast.LENGTH_SHORT).show(); } } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } }
