    - by Imran Omar Bukhsh
    I went through some of the documentation of mysql but cannot understand the difference in the following ways of partitioning : Key vs Hash vs List vs Range.Can someone explain in pure english? Also we have the following table: How do we partition by forum_id?

  • MySQL-problem when baking with CakePHP.

    - by timkl
    I am currently reading "Beginning CakePHP:From Novice to Professional" by David Golding. At one point I have to use the CLI-command "cake bake", I get the welcome-screen but when I try to bake e.g. a Controller I get the following error messages: Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 117 Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 122 Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 130 Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 154 Error: Your database does not have any tables. I suspect that the error-messages has to do with php trying to access the wrong mysql-socket, namely the default osx mysql-socket - instead of the one that MAMP uses. Hence I change my database configurations to connect to the UNIX mysql-socket (:/Applications/MAMP/tmp/mysql/mysql.sock): class DATABASE_CONFIG { var $default = array( 'driver' => 'mysql', 'connect' => 'mysql_connect', 'persistent' => false, 'host' =>':/Applications/MAMP/tmp/mysql/mysql.sock', // UNIX MySQL-socket 'login' => 'my_user', 'password' => 'my_pass', 'database' => 'blog', 'prefix' => '', ); } But I get the same error-messages with the new socket: Warning: mysql_connect(): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock:3306' (2) in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 117 Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 122 Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 130 Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 154 Error: Your database does not have any tables. Also, even though I use the UNIX-socket that MAMP show on it's welcome-screen, CakePHP loses the database-connection, when using this socket instead of localhost. Any ideas on how I can get bake to work?

  • Ab Initio - Formatting a number in Left alignment

    - by Veera
    I have a requirement in Ab Initio to format a number in left alignment. I shouldn't be using String conversion (as Strings are left aligned by default), as it might cause compatibility problems in the other end. For example, if my Field has 7 bytes length, and I'm getting only two digits as my input, then these two digits should go into the first two bytes of my field (left aligned), instead of the last two bytes. So, is there any in-built function in Ab Initio, that can format a number as left aligned?

  • Codeigniter ignoring query strings. Only loading index page.

    - by Keyo
    I have setup remote debugging in netbeans. It works except codeigniter only loads the default controller (home page). I have enabled query strings with $config['enable_query_strings'] = TRUE; The debugger opens up a page with the following url http://blinkfilms.ben.dev/myid/tests?XDEBUG_SESSION_START=netbeans-xdebug So codeigniter should fire up the controller in controllers/myid/tests.php

  • Is there a Grid plugin for jQuery that has similiar capabilities to the Ext-JS Grid?

    - by Ehrann Mehdan
    One of the most appealing features of Ext-JS is the Grid control in my opinion. I was searching for something free that does something close and have set my hopes on jQuery. I haven't found a jQuery (or other LGPL compatible) Table / Grid plugin that allows to: Reorder columns by dragging Resize columns by dragging Add or Remove columns on the fly Have a default good looking UI (subjective, but Ext-JS look I think is a concensus) In addition to the rest most grid controls have (Sort, Paging etc) Is there a free (LGPL) jQuery plugin that does the above?

  • About variadic templates

    - by chedi
    Hi, I'm currently experiencing with the new c++0x variadic templates, and it's quit fun, Although I have a question about the process of member instanciation. in this example, I'm trying to emulate the strongly typed enum with the possibility of choose a random valid strong enum (this is used for unit testing). #include<vector> #include<iostream> using namespace std; template<unsigned... values> struct sp_enum; /* this is the solution I found, declaring a globar var vector<unsigned> _data; and it work just fine */ template<> struct sp_enum<>{ static const unsigned _count = 0; static vector<unsigned> _data; }; vector<unsigned> sp_enum<>::_data; template<unsigned T, unsigned... values> struct sp_enum<T, values...> : private sp_enum<values...>{ static const unsigned _count = sp_enum<values...>::_count+1; static vector<unsigned> _data; sp_enum( ) : sp_enum<values...>(values...) {_data.push_back(T);} sp_enum(unsigned v ) {_data.push_back(v);} sp_enum(unsigned v, unsigned...) : sp_enum<values...>(values...) {_data.push_back(v);} }; template<unsigned T, unsigned... values> vector<unsigned> sp_enum<T, values...>::_data; int main(){ enum class t:unsigned{Default = 5, t1, t2}; sp_enum<t::Default, t::t1, t::t2> test; cout <<test._count << endl << test._data.size() << endl; for(auto i= test._data.rbegin();i != test._data.rend();++i){cout<< *i<< ":";} } the result I'm getting with this code is : 3 1 5: can someone point me what I'm messing here ??? Ps: using gcc 4.4.3

  • Is there any reason to prefer UTF-16 over UTF-8?

    - by Oak
    Examining the attributes of UTF-16 and UTF-8, I can't find any reason to prefer UTF-16. However, checking out Java and C#, it looks like strings and chars there default to UTF-16. I was thinking that it might be for historic reasons, or perhaps for performance reasons, but couldn't find any information. Anyone knows why these languages chose UTF-16? And is there any valid reason for me to do that as well?

  • How to add objects to association in OnPreInsert, OnPreUpdate

    - by Dmitriy Nagirnyak
    Hi, I have an event listener (for Audit Logs) which needs to append audit log entries to the association of the object: public Company : IAuditable { // Other stuff removed for bravety IAuditLog IAuditable.CreateEntry() { var entry = new CompanyAudit(); this.auditLogs.Add(entry); return entry; } public virtual IEnumerable<CompanyAudit> AuditLogs { get { return this.auditLogs } } } The AuditLogs collection is mapped with cascading: public class CompanyMap : ClassMap<Company> { public CompanyMap() { // Id and others removed fro bravety HasMany(x => x.AuditLogs).AsSet() .LazyLoad() .Access.ReadOnlyPropertyThroughCamelCaseField() .Cascade.All(); } } And the listener just asks the auditable object to create log entries so it can update them: internal class AuditEventListener : IPreInsertEventListener, IPreUpdateEventListener { public bool OnPreUpdate(PreUpdateEvent ev) { var audit = ev.Entity as IAuditable; if (audit == null) return false; Log(audit); return false; } public bool OnPreInsert(PreInsertEvent ev) { var audit = ev.Entity as IAuditable; if (audit == null) return false; Log(audit); return false; } private static void LogProperty(IAuditable auditable) { var entry = auditable.CreateAuditEntry(); entry.CreatedAt = DateTime.Now; entry.Who = GetCurrentUser(); // Might potentially execute a query. // Also other information is set for entry here } } The problem with it though is that it throws TransientObjectException when commiting the transaction: NHibernate.TransientObjectException : object references an unsaved transient instance - save the transient instance before flushing. Type: PropConnect.Model.UserAuditLog, Entity: PropConnect.Model.UserAuditLog at NHibernate.Engine.ForeignKeys.GetEntityIdentifierIfNotUnsaved(String entityName, Object entity, ISessionImplementor session) at NHibernate.Type.EntityType.GetIdentifier(Object value, ISessionImplementor session) at NHibernate.Type.ManyToOneType.NullSafeSet(IDbCommand st, Object value, Int32 index, Boolean[] settable, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.WriteElement(IDbCommand st, Object elt, Int32 i, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.PerformInsert(Object ownerId, IPersistentCollection collection, IExpectation expectation, Object entry, Int32 index, Boolean useBatch, Boolean callable, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.Recreate(IPersistentCollection collection, Object id, ISessionImplementor session) at NHibernate.Action.CollectionRecreateAction.Execute() at NHibernate.Engine.ActionQueue.Execute(IExecutable executable) at NHibernate.Engine.ActionQueue.ExecuteActions(IList list) at NHibernate.Engine.ActionQueue.ExecuteActions() at NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions(IEventSource session) at NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event) at NHibernate.Impl.SessionImpl.Flush() at NHibernate.Transaction.AdoTransaction.Commit() As the cascading is set to All I expected NH to handle this. I also tried to modify the collection using state but pretty much the same happens. So the question is what is the last chance to modify object's associations before it gets saved? Thanks, Dmitriy.

  • How to call schedule method in NSObject?

    - by Tattat
    It is my Object.... -(id)init{ if(self = [super init]){ [self schedule:@selector(testCalled:) interval:1.0]; } } -(void)testCalled{ NSLog(@"Called from my Object"); } I already add this line in the .h...: -(void)testCalled; It prompt me that "MyObject" may not respond to -'schedule:interval:', but in my scene, which have a super class CCLayer can call this method,so, I think it is a method from CCLayer, how can I replace it with NSObject default method?

  • Conditionally styling @font-face

    - by Gnee
    I'm using @font-face for some headers. The replaced typeface is different in dimension and overall character. When the switch happens, the old typeface's rules don't look so good. Other than writing a conditional Javascript script, is there a way to have a set of CSS rules for @font-face fonts (if the browsers supports it) and CSS rules for the unreplaced default fonts?

  • ASP.NET site sometimes freezing up and/or showing odd text at top of the page while loading, on load

    - by MGOwen
    I have various servers (dev, 2 x test, 2 x prod) running the same asp.net site. The test and prod servers are in load-balanced pairs (prod1 with prod2, and test1 with test2). The test server pair is exhibiting some kind of (super) slowdown or freezing during about one in ten page loads. Sometimes a line of text appears at the very top of the page which looks something like: 00 OK Date: Thu, 01 Apr 2010 01:50:09 GMT Server: Microsoft-IIS/6.0 X-Powered_By: ASP.NET X-AspNet-Version:2.0.50727 Cache-Control:private Content-Type:text/html; charset=ut (the beginning and end are "cut off".) Has anyone seen anything like this before? Any idea what it means or what's causing it? Edit: I often see this too when clicking something - it comes up as red text on a yellow page: XML Parsing Error: not well-formed Location: http://203.111.46.211/3DSS/CompanyCompliance.aspx?cid=14 Line Number 1, Column 24:2mMTehON9OUNKySVaJ3ROpN" / -----------------------^ If I go back and click again, it works (I see the page I clicked on, not the above error message). Update: ...And, instead of the page loading, I sometimes just get a white screen with text like this in black (looks a lot like the above text): HTTP/1.1 302 Found Date: Wed, 21 Apr 2010 04:53:39 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET X-AspNet-Version: 2.0.50727 Location: /3DSS/EditSections.aspx?id=3&siteId=56&sectionId=46 Set-Cookie: .3DSS=A6CAC223D0F2517D77C7C68EEF069ABA85E9392E93417FFA4209E2621B8DCE38174AD699C9F0221D30D49E108CAB8A828408CF214549A949501DAFAF59F080375A50162361E4AA94E08874BF0945B2EF; path=/; HttpOnly Cache-Control: private Content-Type: text/html; charset=utf-8 Content-Length: 184 object moved here Where "here" is a link that points to a URL just like the one I'm requesting, except with an extra folder in it, meaning something like: http://123.1.2.3/MySite//MySite/Page.aspx?option=1 instead of: http://123.1.2.3/MySite/Page.aspx?option=1 Update: A colleague of mine found some info saying it might be because the test servers are running iis in 64 bit (64bit win 2003) (prod servers are 32 bit win 2003). So we tried telling IIS to use 32 bit: **cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1 %SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i ** (from this MS support page) But iis stopped working altogether (got "server unavailable" on a white page instead of web sites). Reversing the above (see the link) didn't work at first either. The ASP.NET tab disappeared from our IIS web site properties and we had to mess around for an hour uninstalling (aspnet_regiis.exe -u) and reinstalling 32 bit ASP.NET and adding Default.aspx manually back into default documents. We'll probably try again in a few days, if anyone has anything to add in the meantime, please do.

  • What is the big deal with IQueryable?

    - by jjr2527
    I've seen a lot of people talking about IQueryable and I haven't quite picked up on what all the buzz is about. I always work with generic List's and find they are very rich in the way you can "query" them and work with them, even run LINQ queries against them. So I'm wondering if there is a good reason to start considering a different default collection in my projects.

  • How can I generate a flat excel file from a .rdl report?

    - by NotDan
    I have a .rdl report that formats data as a report. I want to export that data to excel as a flat table with the raw data that was returned based on the params in the report. The default excel export looks just like the report which isn't what I want (I just want rows and columns). Is there an easy way to do this?

  • defining class relationships in c# and visual studio 2010

    - by andy
    Hey guys, in Visual Studio 2010 I can point to a bunch of classes and create a diagram. However, the diagram by default doesn't recognize any relationships between the classes, except inheritance and implementations. Is there a way, ideally by using Attributes, to define class and property relationships and associations in such a way that it is picked up by a new Class Diagram automatically? cheers!

  • Email to be sent out from a dedicated server with different IP

    - by ToughPal
    We have three domains hosted on one dedicated server each with its own dedicated IP. Domain A - Has the server primary IP address (default server IP) Domain B - Has its own IP address Domain C - has its own IP address If an email goes out from Domain B then it uses the Domain A IP address in outgoing and this makes emails from Domain B using PHP go straight to spam box of Gmail etc. Is there any way to change the source IP depending on where the email originates from in PHP? What should we change to fix this?

  • Validate xsl fo in xslt styleesheet

    Hi, i have a little problem with validating xml, xslt in details. I have a xslt stylesheet that, transforms xml data source to xsl:fo document.

Is it posible? For now I use dtd validation (I have xsd schema too) for validating Fo, but it give me an error on each xsl tag. Summary. Is it posiible to validate only fo elements against the schema, ignoring xsl tags, and how should I do it? Maybe a code snnippet in C#, or a hint how to modify documents? Thanks in advance!
