  • Extend TTPhotoViewController with custom TTPhotoView

    - by ggould75
    I have successfully integrated the three20 framework in my project, and I have extended the TTPhotoViewController to add some further functionality. Now I need to add some subviews to the TTPhotoView loaded by the TTPhotoViewController. In particular I would like to add that subviews after every TTPhotoView as been loaded. These subviews represents sensible area over the image so they should scale proportionally with the image. The user can tap a subview to get extra info about the image. I don't know how to implement this behavior. Should I extend the TTPhotoView and make sure that the TTPhotoViewController use this extended version instead of its TTPhotoView? Could someone point me to the right direction? Thank you

  • Get python tarfile to skip files without read permission

    - by chris
    I'm trying to write a function that backs up a directory with files of different permission to an archive on Windows XP. I'm using the tarfile module to tar the directory. Currently as soon as the program encounters a file that does not have read permissions, it stops giving the error: IOError: [Errno 13] Permission denied: 'path to file'. I would like it to instead just skip over the files it cannot read rather than end the tar operation. This is the code I am using now: def compressTar(): """Build and gzip the tar archive.""" folder = 'C:\\Documents and Settings' tar = tarfile.open ("C:\\WINDOWS\\Program\\archive.tar.gz", "w:gz") try: print "Attempting to build a backup archive" tar.add(folder) except: print "Permission denied attempting to create a backup archive" print "Building a limited archive conatining files with read permissions." for root, dirs, files in os.walk(folder): for f in files: tar.add(os.path.join(root, f)) for d in dirs: tar.add(os.path.join(root, d))

  • Performance of delegate and method group

    - by BlueFox
    Hi I was investigating the performance hit of creating Cachedependency objects, so I wrote a very simple test program as follows: using System; using System.Collections.Generic; using System.Diagnostics; using System.Web.Caching; namespace Test { internal class Program { private static readonly string[] keys = new[] {"Abc"}; private static readonly int MaxIteration = 10000000; private static void Main(string[] args) { Debug.Print("first set"); test7(); test6(); test5(); test4(); test3(); test2(); Debug.Print("second set"); test2(); test3(); test4(); test5(); test6(); test7(); } private static void test2() { DateTime start = DateTime.Now; var list = new List<CacheDependency>(); for (int i = 0; i < MaxIteration; i++) { list.Add(new CacheDependency(null, keys)); } Debug.Print("test2 Time: " + (DateTime.Now - start)); } private static void test3() { DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(() => new CacheDependency(null, keys)); } Debug.Print("test3 Time: " + (DateTime.Now - start)); } private static void test4() { var p = new Program(); DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(p.GetDep); } Debug.Print("test4 Time: " + (DateTime.Now - start)); } private static void test5() { var p = new Program(); DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(() => { return p.GetDep(); }); } Debug.Print("test5 Time: " + (DateTime.Now - start)); } private static void test6() { DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(GetDepSatic); } Debug.Print("test6 Time: " + (DateTime.Now - start)); } private static void test7() { DateTime start = DateTime.Now; var list = new List<Func<CacheDependency>>(); for (int i = 0; i < MaxIteration; i++) { list.Add(() => { return GetDepSatic(); }); } Debug.Print("test7 Time: " + (DateTime.Now - start)); } private CacheDependency GetDep() { return new CacheDependency(null, keys); } private static CacheDependency GetDepSatic() { return new CacheDependency(null, keys); } } } But I can't understand why these result looks like this: first set test7 Time: 00:00:00.4840277 test6 Time: 00:00:02.2041261 test5 Time: 00:00:00.1910109 test4 Time: 00:00:03.1401796 test3 Time: 00:00:00.1820105 test2 Time: 00:00:08.5394884 second set test2 Time: 00:00:07.7324423 test3 Time: 00:00:00.1830105 test4 Time: 00:00:02.3561347 test5 Time: 00:00:00.1750100 test6 Time: 00:00:03.2941884 test7 Time: 00:00:00.1850106 In particular: 1. Why is test4 and test6 much slower than their delegate version? I also noticed that Resharper specifically has a comment on the delegate version suggesting change test5 and test7 to "Covert to method group". Which is the same as test4 and test6 but they're actually slower? 2. I don't seem a consistent performance difference when calling test4 and test6, shouldn't static calls to be always faster?

  • Registry corrupted for testing?

    - by Emile
    Hi. Forgive my ignorance. I'm a lowly LAMP stack developer and this is my first post for "c++". We had an Internet Explorer add-on commissioned but then lost support. Allegedly each version has to be have been tested "on a fresh computer since old add-ons could have cause registry errors." I'm not familiar with IE add-on development (or c++ dev). Is this common? Can't one simply reverse registry errors? How to continue testing iterations on one machine? Thanks!

  • Subset sum problem

    - by MadBoy
    I'm having a problem with counting which is continuation of this question. I am not really a math person so it's really hard for me to figure out this subset sum problem which was suggested as resolution. I'm having 4 ArrayList in which I hold data: alId, alTransaction, alNumber, alPrice Type | Transaction | Number | Price 8 | Buy | 95.00000000 | 305.00000000 8 | Buy | 126.00000000 | 305.00000000 8 | Buy | 93.00000000 | 306.00000000 8 | Transfer out | 221.00000000 | 305.00000000 8 | Transfer in | 221.00000000 | 305.00000000 8 | Sell | 93.00000000 | 360.00000000 8 | Sell | 95.00000000 | 360.00000000 8 | Sell | 126.00000000 | 360.00000000 8 | Buy | 276.00000000 | 380.00000000 In the end I'm trying to get what's left for customer and what's left I put into 3 array lists: alNew (corresponds to alNumber), alNewPoIle (corresponds to alPrice), and alNewCo (corrseponds to alID) ArrayList alNew = new ArrayList(); ArrayList alNewPoIle = new ArrayList(); ArrayList alNewCo = new ArrayList(); for (int i = 0; i < alTransaction.Count; i++) { string tempAkcjeCzynnosc = (string) alTransaction[i]; string tempAkcjeInId = (string) alID[i]; decimal varAkcjeCena = (decimal) alPrice[i]; decimal varAkcjeIlosc = (decimal) alNumber[i]; int index; switch (tempAkcjeCzynnosc) { case "Transfer out": case "Sell": index = alNew.IndexOf(varAkcjeIlosc); if (index != -1) { alNew.RemoveAt(index); alNewPoIle.RemoveAt(index); alNewCo.RemoveAt(index); } else { ArrayList alTemp = new ArrayList(); decimal varAkcjeSuma = 0; for (int j = 0; j < alNew.Count; j ++) { string akcjeInId = (string) alNewCo[j]; decimal akcjeCena = (decimal) alNewPoIle[j]; decimal akcjeIlosc = (decimal) alNew[j]; if (tempAkcjeInId == akcjeInId && akcjeCena == varAkcjeCena) { alTemp.Add(j); varAkcjeSuma = varAkcjeSuma + akcjeIlosc; } } if (varAkcjeSuma == varAkcjeIlosc) { for (int j = alTemp.Count -1 ; j >=0 ; j --) { int tempIndex = (int) alTemp[j]; alNew.RemoveAt(tempIndex); alNewPoIle.RemoveAt(tempIndex); alNewCo.RemoveAt(tempIndex); } } } break; case "Transfer In": case "Buy": alNew.Add(varAkcjeIlosc); alNewPoIle.Add(varAkcjeCena); alNewCo.Add(tempAkcjeInId); break; } } Basically I'm adding and removing things from Array depending on Transaction Type, Transaction ID and Numbers. I'm adding numbers to ArrayList like 156, 340 (when it is TransferIn or Buy) etc and then i remove them doing it like 156, 340 (when it's TransferOut, Sell). My solution works for that without a problem. The problem I have is that for some old data employees were entering sum's like 1500 instead of 500+400+100+500. How would I change it so that when there's Sell/TransferOut or Buy/Transfer In and there's no match inside ArrayList it should try to add multiple items from thatArrayList and find elements that combine into aggregate. Inside my code I tried to resolve that problem with simple summing everything when there's no match (index == 1) if (index != -1) { alNew.RemoveAt(index); alNewPoIle.RemoveAt(index); alNewCo.RemoveAt(index); } else { ArrayList alTemp = new ArrayList(); decimal varAkcjeSuma = 0; for (int j = 0; j < alNew.Count; j ++) { string akcjeInId = (string) alNewCo[j]; decimal akcjeCena = (decimal) alNewPoIle[j]; decimal akcjeIlosc = (decimal) alNew[j]; if (tempAkcjeInId == akcjeInId && akcjeCena == varAkcjeCena) { alTemp.Add(j); varAkcjeSuma = varAkcjeSuma + akcjeIlosc; } } if (varAkcjeSuma == varAkcjeIlosc) { for (int j = alTemp.Count -1 ; j >=0 ; j --) { int tempIndex = (int) alTemp[j]; alNew.RemoveAt(tempIndex); alNewPoIle.RemoveAt(tempIndex); alNewCo.RemoveAt(tempIndex); } } But it only works if certain conditions are met, and fails for the rest.

  • Using Interfaces in JNI

    - by lhw
    I am trying to use (*env)->RegisterNatives to add methods to a defined class which I then add to a callback list. The callback sender of course expects my class to implement a certain interface which I do not. And is failing on execution. If I add the keyword "implements Listener" to my class in Java the javac expects to have the methods definition in Java or with native keyword which I try to avoid here, as I'd like to register the methods within the JNI_OnLoad and execute one of them afterwards. The question now is: Can I implement the interface in JNI or avoid the error message in Java?

  • Rails3. How do I display two different objects in a search?

    - by JZ
    I am using a simple search that displays search results: @adds = Add.search(params[:search]) In addition to the search results I'm trying to utilize a method, nearbys(), which displays objects that are close in proximity to the search result. The following method displays objects which are close to 2, but it does not display object 2. How do I display object 2 in conjunction with the nearby objects? @adds = Add.find(2).nearbys(10) While the above code functions, when I use search, @adds = Add.search(params[:search]).nearbys(10) a no method error is returned, undefined methodnearbys' for Array:0x30c3278` How can I search the model for an object AND use the nearbys() method AND display all results returned?

  • Magento Admin Custom Sales Report

    - by Ela
    Hi, I have to develop a module to export collection of product,order,customer combined attributes. So i thought rather than modifying the core sales report for this purpose better to do a custom functionality. These are the steps that i did but i am not able to produce it. Used magento 1.4.1 version for this. Under /var/www/magento141/app/code/core/Mage/Reports/etc/adminhtml.xml Added these lines for menus. <ereaders translate="title" module="reports"> <title>EReader Sales Report</title> <children> <ereaders translate="title" module="reports"> <title>Sales Report</title> <action>adminhtml/report_sales/ereaders</action> </ereaders> </children> </ereaders> Under /var/www/magento141/app/design/adminhtml/default/default/layout/sales.xml Added these lines for filter condition. <adminhtml_report_sales_ereaders> <update handle="report_sales"/> <reference name="content"> <block type="adminhtml/report_sales_sales" template="report/grid/container.phtml" name="sales.report.grid.container"> <block type="adminhtml/store_switcher" template="report/store/switcher/enhanced.phtml" name="store.switcher"> <action method="setStoreVarName"><var_name>store_ids</var_name></action> </block> <block type="sales/adminhtml_report_filter_form_order" name="grid.filter.form"> ---- </block> </block> </reference> </adminhtml_report_sales_ereaders> And then copied the needed block,model files from sales and renamed all of them into ereaders under /var/www/magento141/app/code/core/Mage/Adminhtml/. Then placed action for ereaders under /var/www/magento141/app/code/core/Mage/Adminhtml/controllers/Report/SalesController.php public function ereadersAction() { $this->_title($this->__('Reports'))->_title($this->__('Sales'))->_title($this->__('EReaders Sales')); $this->_showLastExecutionTime(Mage_Reports_Model_Flag::REPORT_ORDER_FLAG_CODE, 'ereaders'); $this->_initAction() ->_setActiveMenu('report/sales/ereaders') ->_addBreadcrumb(Mage::helper('adminhtml')->__('EReaders Sales Report'), Mage::helper('adminhtml')->__('EReaders Sales Report')); $gridBlock = $this->getLayout()->getBlock('report_sales_ereaders.grid'); $filterFormBlock = $this->getLayout()->getBlock('grid.filter.form'); $this->_initReportAction(array( $gridBlock, $filterFormBlock )); $this->renderLayout(); } Here when i use var_dump == //var_dump($this-getLayout()-getBlock('report_sales_ereaders.grid')); am getting bool(false) only. It does not call the ereaders grid, instead of its still loading blocks and grids from Sales only. I searched most of the files related to report, am not still able to find out the problem. Hope many of you gone through these sort of issues, please can anyone tell me where am making mistake or missing something.

    I have created a repository AAA and another BBB. In AAA I have created a file A with the values a1, a2, a3 and commit In BBB I have created a file B with the values b1, b2, b3, commit and export a bundle. I add the bundle in AAA and merge. I make a change in B, and write b33 in AAA and another change in B and write b23 in BBB. and commit both. I create bundle of BBB and add the bundle in AAA. I do a merge. Now I decide to revert to the revert to step 2. I no more want to have the merge of 4. changes done in B as they were bad merges. Now I want to add the bundle of 3 but I can see that it can`t see any changes anymore. Why? How can I do the merge once more?

  • Repopulating a collection of Backbone forms with previously submitted data

    I am able to post my forms to my database and I have stepped through my back end function to check and see that my Get function is returning the same data I submitted.

  • Whats faster in Javascript a bunch of small setInterval loops, or one big one?

    - by RobertWHurst
    Just wondering if its worth it to make a monolithic loop function or just add loops were they're needed. The big loop option would just be a loop of callbacks that are added dynamically with an add function. adding a function would look like this setLoop(function(){ alert('hahaha! I\'m a really annoying loop that bugs you every tenth of a second'); }); setLoop would add the function to the monolithic loop. so is the is worth anything in performance or should I just stick to lots of little loops using setInterval?

  • In SQL, in what situation do we want to Index a field in a table, or 2 fields in a table at the same

    - by Jian Lin
    In SQL, it is obvious that whenever we want to do a search on millions of record, say CustomerID in a Transactios table, then we want to add an index for CustomerID. Is another situation we want to add an index to a field when we need to do inner join or outer join using that field as a criteria? Such as Inner join on t1.custumerID = t2.customerID. Then if we don't have an index on customerID on both tables, we are looking at O(n^2) because we need to loop through the 2 tables sequentially. If we have index on customerID on both tables, then it becomes O( (log n) ^ 2 ) and it is much faster. Any other situation where we want to add an index to a field in a table? What about adding index for 2 fields combined in a table. That is, one index, for 2 fields together?

    This is pure just for interest question, any sort of questions are welcome. So is it possible to create thread-safe collections without any locks? By locks I mean any thread synchronization mechanisms, including Mutex, Semaphore, and even Interlocked, all of them. Is it possible at user level, without calling system functions? Ok, may be implementation is not effective, i am interested in theoretical possibility. If not what is the minimum means to do it? EDIT: Why immutable collections don't work. This of class Stack with methods Add that returns another Stack. Now here is program: Stack stack = new ...; ThreadedMethod() { loop { //Do the loop stack = stack.Add(element); } } this expression stack = stack.Add(element) is not atomic, and you can overwrite new stack from other thread. Thanks, Andrey

  • How to define using statements in web.config?

    - by Hasan Gürsoy
    I'm using MySql in my asp.net project. But I don't want to type every "using MySql.Data.MySqlClient;" statement in every aspx.cs file. How can I define this lines in web.config file? I've defined some namespaces like below but this only works for aspx pages: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="false" targetFramework="4.0"/> <pages> <namespaces> <add namespace="System.Web.Configuration"/> <add namespace="MySql.Data"/> <add namespace="MySql.Data.MySqlClient"/> </namespaces> </pages> </system.web> </configuration>
