  • Storing a reference to an object in C#

    - by Jack
    I was wondering how one could store a reference to an object in .net. That is, I would like something like the following code (note, of course, that the following code may be way off from how to actually do it): class Test { private /*reference to*/ Object a; public Test(ref int a) { this.a = a; this.a = ((int)this.a) + 1; } public Object getA() { return this.a; } } /* * ... */ static void Main(string[] args) { int a; a=3; Test t = new Test(ref a); Console.WriteLine(a); Console.WriteLine(t.getA()); Console.ReadKey(); } To produce the following output: 4 4 Ideally, I would like to do this without writing a wrapper class around the integer. In other words, I think I want pointers in .Net.

  • Best .NET Framework compression class?

    - by Jack
    Hi all Yes, I know GZipStream or DeflateStream is the common ones in .NET Framework which handle compression/decompression. I wish to have compress/decompress functions in my program, but I wish a .NET Framework C# one, not a 3rd party open source. I can't use because of those copyright restrictions in my program. GZipStream and DeflateStream are not so good. for e.g., GZipStream compress a file to 480KB while 7Zip compress the same file to the size of 57KB. Does Microsoft have other good compression methods??? Thanks

  • Fluxbox compiling problems after making a change.

    - by Jack
    I'm trying to make the change here: http://fluxbox-wiki.org/index.php?title=Howto_Make_dblclick_titlebar_maximize I am using the current git version of the fluxbox source. I assume that those instructions are perhaps no longer valid for the current git version. In the void FluxboxWindow::setupWindow() function I can see no references to CommandRef or frame. I would like to know if it is possible that I could work out where they should go in that function, with only having a limited knowledge? I am still trying to learn programming and don't know enough just yet to work out where they should go. I assume I can't just paste in the suggested lines anywhere in that function, but why not? I can paste the source if needed, but I am unsure where to paste to.

  • Retrieve names by ratio of their occurance

    - by jjiffer
    Hello, I'm somewhat new to SQL queries, and I'm struggling with this particular problem. Let's say I have query that returns the following 3 records (kept to one column for simplicity): Tom Jack Tom And I want to have those results grouped by the name and also include the fraction (ratio) of the occurrence of that name out of the total records returned. So, the desired result would be (as two columns): Tom | 2/3 Jack | 1/3 How would I go about it? Determining the numerator is pretty easy (I can just use COUNT() and GROUP BY name), but I'm having trouble translating that into a ratio out of the total rows returned. Any help is much appreciated!

  • Grails deploy on Tomcat6

    - by Jack
    Hello, while trying to deploy a Grails application into tomcat6 I ran into some problems: I used the grails war command to build up a war, then copied it to var/lib/tomcat6/webapps and tried to restart the container. I had to change default Tomcat policy to skip security exceptions, since I couldn't access environment variable (like grails.env), then tried again but it gives me an exception related to instantiating something, but it's not clear where should I try to fix the error, according to tomcat6 logs the problem is: SEVERE: Exception sending context initialized event to listener instance of class org.codehaus.groovy.grails.web.context.GrailsC$ org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pluginManager' defined in ServletContext$ at java.lang.Thread.run(Thread.java:619) Caused by: org.codehaus.groovy.grails.exceptions.NewInstanceCreationException: Could not create a new instance of class [Hiberna$ ... 1 more Caused by: java.lang.NoClassDefFoundError: org.hibernate.cfg.Environment It seems like it's unable to load org.hibernate.cfg.Environment class. I checked the applicationContext.xml and it refers to grails.xml to search for plugins, in this last file I actually have HibernateGrailsPlugin. Where should I look to find if the plugin is present?

  • MySQL slow queries

    - by jack
    The MySQL slow query log often shows a bunch of following entries in sequence. SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 4.172700 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 3.628924 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 3.116018 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 ... Usually 6-7 "commit" queries in sequence. Anyone what they are and what's the preceding query of each of them? Thanks in advance.

  • Forcing deallocation of large cache object in Java

    - by Jack
    I use a large (millions) entries hashmap to cache values needed by an algorithm, the key is a combination of two objects as a long. Since it grows continuously (because keys in the map changes, so old ones are not needed anymore) it would be nice to be able to force wiping all the data contained in it and start again during the execution, is there a way to do effectively in Java? I mean release the associated memory (about 1-1.5gb of hashmap) and restart from the empty hashmap..

  • sharepoint: editing webpart caml

    - by Jack
    I added this code to my sharepoint content query web part, which is looking at an events list from my calender, .webpart file in order to only show recurring events within the next month and regular events within the next month. However, I can't get the web part imported and working. Also is there any way to replace <Month /> with a range like <Today:Today OffsetDays="30"/> except with valid code? Here is the code: <property name="QueryOverride" type="string"> <Where> <Or> <And> <Neq> <FieldRef Name="FRecurrence"/> <Value Type="Recurrance">1</Value> </Neq> <And> <Lt> <FieldRef Name="EventDate" Type="DateTime"/> <Value Type="DateTime"><Today OffsetDays="30"/></Value> </Lt> <Gt> <FieldRef Name="EventDate" Type="DateTime"/> <Value Type="DateTime"><Today /></Value> </Gt> </And> </And> <DataRangesOverlap> <FieldRef Name="EventDate" /> <FieldRef Name="EndDate" /> <FieldRef Name="RecirrenceId" /> <Value Type="DateTime"><Month /></Value> </DataRangesOverlap> </Or> </Where> </property> When I upload this I get "Unable to add selected web part(s). The file format is not valid" and when I add <![CDATA[ and ]]> I can import it but the query doesn't return anything. How can I get this to work?

  • Iphone & Web App synch

    - by Jack Welsh
    I am trying to build an Iphone App client for our CRM solution so our sales people would be able to access the information available in our CRM through an Iphone App. I am trying to find out what is the recommended approach to architect the application when it comes to the database. I am not sure where should the data reside, should I save a subset of the data on the iPhone, or should I just rely on webservices and pull the information I need from the database whenever I need it. Also, is there any best practices or frameworks to build such applications on the Iphone.

  • Constructor and Destructors in C++ [Not a question] [closed]

    - by Jack
    I am using gcc. Please tell me if I am wrong - Lets say I have two classes A & B class A { public: A(){cout<<"A constructor"<<endl;} ~A(){cout<<"A destructor"<<endl;} }; class B:public A { public: B(){cout<<"B constructor"<<endl;} ~B(){cout<<"B destructor"<<endl;} }; 1) The first line in B's constructor should be a call to A's constructor ( I assume compiler automatically inserts it). Also the last line in B's destructor will be a call to A's destructor (compiler does it again). Why was it built this way? 2) When I say A * a = new B(); compiler creates a new B object and checks to see if A is a base class of B and if it is it allows 'a' to point to the newly created object. I guess that is why we don't need any virtual constructors. ( with help from @Tyler McHenry , @Konrad Rudolph) 3) When I write delete a compiler sees that a is an object of type A so it calls A's destructor leading to a problem which is solved by making A's destructor virtual. As user - Little Bobby Tables pointed out to me all destructors have the same name destroy() in memory so we can implement virtual destructors and now the call is made to B's destructor and all is well in C++ land. Please comment.

  • warning: returning reference to temporary

    - by Jack
    I have a function like this const string &SomeClass::Foo(int Value) { if (Value < 0 or Value > 10) return ""; else return SomeClass::StaticMember[i]; } I get warning: returning reference to temporary. Why is that? I thought the both values the function returns (reference to const char* "" and reference to a static member) cannot be temporary.

  • Auto Generated - CREATE Table Script in SQL 2008 throws error

    - by jack
    I scripted the tables in my dev database using SQL 2008 - generate scripts option (Datbase-right click-Tasks-Generate Scripts) and ran it on the staging database, but the script throws the below error for each table Msg 102, Level 15, State 1, Line 1 Incorrect syntax near '('.

  • TCP and UDP are using different OS Buffer?

    - by Jack
    HI all. Here is the scenario. I have port 8888 for my program to use. I build a TCP and a UDP listener on that port. (This can do, c# allows, because they are two different protocols) My question is If the network traffic is very busy, TCP sockets may refuse or signalling the other end to stop sending things, it is called congestion control, right? So if TCP is congestion controlling, other ends may not send more data, in this "TCP quiet period", UDP channel should have not that much of traffic, right? I want to figure out the TCP traffic will affect UDP traffic or not?

  • How to disable html button using JavaScript?

    - by Jack Roscoe
    Hi, I've read that you can disable (make physically unclickable) a html button simply but appending 'disable' to its tag, but not as an attribute, as follows: <input type="button" name=myButton value="disable" disabled> Since this setting is not an attribute, how can I add this in dynamically via JavaScript to disable a button that was previously enabled?

  • Dynamic select menu Rails, Javascript HABTM

    - by Jack
    Hi, I am following a tutorial in one of Ryan Bates' Railscasts here. Basically I want a form where there are 2 drop down menus, the contents of one are dependent on the other. I have Years and Courses, where Years HABMT Courses and Courses HABTM Years. In the tutorial, the javascript is as follows: var states = new Array(); <% for state in @states -%> states.push(new Array(<%= state.country_id %>, '<%=h state.name %>', <%= state.id %>)); <% end -%> function countrySelected() { country_id = $('person_country_id').getValue(); options = $('person_state_id').options; options.length = 1; states.each(function(state) { if (state[0] == country_id) { options[options.length] = new Option(state[1], state[2]); } }); if (options.length == 1) { $('state_field').hide(); } else { $('state_field').show(); } } document.observe('dom:loaded', function() { countrySelected(); $('person_country_id').observe('change', countrySelected); }); Where I guess country has many states and state belongs to country. I think what I need to do is edit the first for statement to somehow loop through all of the courses for each year_id, but don't know how to do this. Any ideas? Thanks
