  • Scala match/compare enumerations

    - by williamstw
    I have an enumeration that I want to use in pattern matches in an actor. I'm not getting what i'd expect and, now, I'm suspecting I'm missing something simple. My enumeration, object Ops extends Enumeration { val Create = Value("create") val Delete = Value("delete") } Then, I create an Ops from a String: val op = Ops.valueOf("create") Inside my match, I have: case (Ops.Create, ...) But Ops.Create doesn't seem to equal ops.valueOf("create") The former is just an atom 'create' and the later is Some(create) Hopefully, this is enough info for someone to tell me what I'm missing... Thanks

  • problem in `delete-directory` with enabled `delete-by-removing-to-trash`

    - by Andreo
    There is a strange behavior of delete-directory function with enabled flag delete-by-removing-to-trash. It deletes files one by one instead of applying move-file-to-trash to the directory. As a result emacs deletes big directories slowly and there are many files in the trash after deleting, so it is impossible to restore the directory. Example: Directory structure: ddd/ ccc/ 1.txt There are three files in the trash after deleting ddd: trash/ ddd/ ccc/ 1.txt instead of one: trash/ ddd/ It is very slow, because emacs traverse directory recursively. I can't restore deleted directory. What i need is exactly the same behavior as of move-file-to-trash. But it should be transparent (i.e. 'D x' in dired mode). How to solve the problem? As a temporary solution i see the making advice function for `delete-directory'.

    - by vedactive
    Again i rewrite my question with more details i.e. I am developing a website in Asp.net 2.0 in that i'm tracking the user's some details like their id,no of page hitted and time of hitting etc, in a LogfileDate(the LogfileDate contains whole day summary of all users) saved inside a folder(Folder is inside my project). And at another day when a new logfileDate created i want to mail the previous day Logfile and delete that file after sending. Everything happened but when It is going to delete its shows file is accessed by another process. So I need to refresh that folder after sending mail so that it got free with buffer.

  • iPhone application build fails with "dyld: Library not loaded: /System/[...]" error? Why?

    - by Andrew J. Brehm
    For my own reasons and not for the app store I am referencing the Apple private framework Apple80211 in an iPhone app. I got the framework from an earlier version of the iPhone SDK. I added the "existing framework", verified that that absolute path to the framework is /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk/System/Library/PrivateFrameworks/Apple80211.framework and tried to build the app. But the build (to device) fails with the error dyld: Library not loaded: /System/Library/PrivateFrameworks/Apple80211.framework/Apple80211 Referenced from: /var/mobile/Applications/3691587D-87AF-44EA-A505-F73D17F39B3B/iWire2.app/iWire2 Reason: image not found I cannot figure out why Xcode would look for the library in a /System path (instead of using the path given in the frameworks list) or how to change that behaviour. I tried the tricks I found here and elsewhere for similar (and identical) sitiations: Delete the myusername.* files in the xcodeproj bundle Delete the build directory Clean all targets Start new project Result is always the same. How can I add this (or a) framework to an iPhone project AND get Xcode to at least look at the library located where I point to rather than a location in /System?

  • How can I clear the Android app cache?

    - by Srao
    I am writing a app which can programatically clear application cache of all the third party apps installed on the device. Following is the code snippet for Android 2.2 public static void trimCache(Context myAppctx) { Context context = myAppctx.createPackageContext("com.thirdparty.game", Context.CONTEXT_INCLUDE_CO|Context.CONTEXT_IGNORE_SECURITY); File cachDir = context.getCacheDir(); Log.v("Trim", "dir " + cachDir.getPath()); if (cachDir!= null && cachDir.isDirectory()) { Log.v("Trim", "can read " + cachDir.canRead()); String[] fileNames = cachDir.list(); //Iterate for the fileName and delete } } My manifest has following permissions: android.permission.CLEAR_APP_CACHE android.permission.DELETE_CACHE_FILES Now the problem is that the name of the cache directory is printed but the list of files cachDir.list() always returns null. I am not able to delete the cache directory since the file list is always null. Is there any other way to clear the application cache?

  • Removing a Subversion folder from the client and server

    - by Code Sherpa
    Hi. I have been using Subversion for a few days now and have a question... I have a folder deep in my subversion trunk that I want to remove and replace with another folder. I have read about this on here and tried: Export: I clicked on the folder I wanted to remove I then created a new backup folder elsewhere when prompted I then exported Delete: I next chose the delete option (in TortoiseSVN) on the folder I wanted to remove and clicked it. The folder I want to remove now has an "X" over it as does all of the subfolders and files. But, when I go to the Subversion repository on the remote server, I still see the folder I want to remove and all of its files. What do I have to do to get the clients to forget about this folder and the Subversion server to remove it permanently from its sub-folders? Thanks in advance...

  • Is It Safe to Cast Away volatile?

    - by Yan Cheng CHEOK
    Most of the time, I am doing this way. class a { public: ~ a() { i = 100; // OK delete (int *)j; // Compiler happy. But, is it safe? // Error : delete j; } private: volatile int i; volatile int *j; }; int main() { a aa; } However, I saw an article here: https://www.securecoding.cert.org/confluence/display/seccode/EXP32-C.+Do+not+access+a+volatile+object+through+a+non-volatile+reference Casting away volatile allows access to an object through a non-volatile reference. This can result in undefined and perhaps unintended program behavior. So, what will be the workaround for my above code example?

  • Dynamic allocating of const member structures

    - by Willy
    I've got class which is using plain-only-data struct with const variables and I'm not sure, if I'm allocating these structures in a proper way. It looks more or less like: #include <cstdlib> #include <iostream> using std::cout; using std::endl; struct some_const_struct { const int arg1; const int arg2; }; class which_is_using_above_struct { public: some_const_struct* m_member; const some_const_struct* const m_const_member; public: const some_const_struct& get_member() const { return *m_member; } const some_const_struct& get_const_member() const { return *m_const_member; } void set_member(const int a, const int b) { if(m_member != NULL) { delete m_member; m_member = NULL; } m_member = new some_const_struct((some_const_struct){a, b}); } explicit which_is_using_above_struct(const int a, const int b) : m_const_member(new some_const_struct((const some_const_struct){a, b})) { m_member = NULL; } ~which_is_using_above_struct() { if(m_member != NULL) { delete m_member; } if(m_const_member != NULL) { delete m_const_member; } } }; int main() { which_is_using_above_struct c(1, 2); c.set_member(3, 4); cout << "m_member.arg1 = " << c.get_member().arg1 << endl; cout << "m_member.arg2 = " << c.get_member().arg2 << endl; cout << "m_const_member.arg1 = " << c.get_const_member().arg1 << endl; cout << "m_const_member.arg2 = " << c.get_const_member().arg2 << endl; return 0; } I'm just not quite sure if the statement: m_member = new some_const_struct((some_const_struct){a, b}); doesn't produce unnessesary use of some_const_struct's copy constructor, ergo allocating that struct twice. What do you think? And is it reasonable to make that struct's members const? (they're not supposed to change in their lifetime at all)

  • jQuery UI Themes

    - by Theopile
    So I downloaded a jQuery UI Theme and link it, but it looks nothing like the them on the site. The buttons are huge and so is the text. <link rel="stylesheet" type="text/css" href="/css/trontastic/jquery-ui-1.8.2.custom.css"> $('#Delete').dialog({ modal: true, autoOpen: false, title: "Delete?", buttons: { "Yes": function(){ $(this).dialog('close'); $('li#'+$id).remove(); $('.nav').sortUpdate(); }, "No":function(){ $(this).dialog('close'); } }, draggable: false, resizable: false }); Am I missing something or is there addition css that I have to handcode? Thanks

  • Hudson: where to download file and stop specific builds running ?

    - by Kim Jong Woo
    I have a file that is generated inside (hudson server) /var/lib/hudson/jobs/jobtitle/1/out.txt I need to fetch this file, but doing a GET request for http://myhudson:8090/job/jobtitle/1/out.txt doesn't actually locate the file. Basically, I have another box that will grab this file from the hudson server. This box will make the out.txt file available for download. Another challenge is the build number directories. How would I be able to use the hudson API to stop or delete the specific builds running ? I am forced to do iterate through all build numbers to send STOP or DELETE api call in php using wget to do the REST API call. This is not very efficient. for ($i=0; $i < 3000; $i++){ exec('wget -O /dev/null "http://myhudson:8090/job/' . 'jobtitle' . '/$i/stop"'); }

  • MySQL Query still executing after a day..?

    - by Matt Jarvis
    Hi - I'm trying to isolate duplicates in a 500MB database and have tried two ways to do it. One creating a new table and grouping: CREATE TABLE test_table as SELECT * FROM items WHERE 1 GROUP BY title; But it's been running for an hour and in MySQL Admin it says the status is Locked. The other way I tried was to delete duplicates with this: DELETE bad_rows.* from items as bad_rows inner join ( select post_title, MIN(id) as min_id from items group by title having count(*) 1 ) as good_rows on good_rows.post_title = bad_rows.post_title; ..and this has been running for 24hours now, Admin telling me it's Sending data... Do you think either or these queries are actually still running? How can I find out if it's hung? (with Apple OS X 10.5.7)

  • how to combine changes tracked from several documents

    - by Jessica
    I tried to search the solution in internet, but found nothing, is there anyone who can help me? For my application, there is one document (Microsoft word), and this document is reviewed by several people in the "Track changes" mode, so the input to my application is the original document and the reviewed documents with changes (like insert/delete/comments). By this link , I know how to extract all the changes from the reviewed documents. what i want is to combine all the changes from all the reviewed documents into ONE document, and make all the changes "accepted", so the output of my application is one modified Microsoft document with all the changes (delete/insert/comment) accepted. My problem is that I don't know how to combine the changes from several documents into one single document. Anyone has an idea how to do this? Thank you very much in advance.

  • Managing memory of polymorphic timed events with DLL

    - by Milo
    Here is my issue. My Gui library that I made supports timed events. Basically, I have a class called TimedEvent which users inherit from. They then do: addTimedEvent(new DerivedTimedEvent(...)); However given the nature of timed events, I manage the memory afterwards. So when the timed event has done its thing, my library calls delete on it. Although it runs fine, that is because the exe and the library were both built with msvc 2008. I think I might have trouble if I have 2 versions of the runtime, one for the lib, and one for the exe. What can I do to fix this? I can't create a factory because the derived type is on the exe side of things. I also cannot ask the user to call delete since they might not have a way to keep track of time, or know if the event was delayed for whatever reason. Thanks

  • What value should .net SqlCommand.ExecuteNonQuery() return if no rows are affected?

    - by peacedog
    I have the following code: int result = -1; StringBuilder sb = new StringBuilder(); SqlCommand cmd = MyConnection. sb.AppendLine("delete from Table1 where ID in"); sb.AppendLine("(select id from Table1 t1 where not exists(select * from Table2 t2 where t2.Table1ID = t1.ID))"); cmd.CommandText = sb.ToString(); result = cmd.ExecuteNonQuery(); _log.Info("StoredXMLDocument Records Deleted: " + result.ToString()); That SQL, in a more readable format, is: delete from Table1 where ID in (select id from Table1 t1 where not exists(select * from Table2 t2 where t2.Table1ID = t1.ID)) I know that the SQL, when executed directly in the database, deletes no rows. When this code runs, however, result gets a value of 1. I was expecting it to be 0. Am I missing something? Why is it 1?

  • copy C'tor with operator= | C++

    I've got this code here: class DerivedClass : public BaseClass { SomeClass* a1; Someclass* a2; public: //constructors go here ~DerivedClass() { delete a1; delete a2;} // other functions go here .... }; My first question is as follows: Can I write an "operator=" to "DerivedClass" ? (if your answer is yes, could you show me how?) My second question is: If the answer to the above is yes, could you show me how to make an "copy c'tor" using the "operator=" that you wrote beforehand (if that is even possible)? Your help would be much appreciated !

  • History tables pros, cons and gotchas - using triggers, sproc or at application level.

    - by Nathan W
    I am currently playing around with the idea of having history tables for some of my tables in my database. Basically I have the main table and a copy of that table with a modified date and an action column to store what action was preformed eg Update,Delete and Insert. So far I can think of three different places that you can do the history table work. Triggers on the main table for update, insert and delete. (Database) Stored procedures. (Database) Application layer. (Application) My main question is, what are the pros, cons and gotchas of doing the work in each of these layers. One advantage I can think of by using the triggers way is that integrity is always maintained no matter what program is implmentated on top of the database.
