  • Unbox an Object to Its Type

    - by Ngu Soon Hui
    Hello, is there anyway to unbox an object to its real type? Basically I am given an ArrayList, the array list are actually a list of int or double, or maybe other types ( it can be either, but it is either all int or double, no mix). Now, I will have to return a List<double> or List<int> or other list, depending on what is the real type. public List<T> ConvertToList<T>(ArrayList arr) { var list1 = new List<T>(); foreach(var obj in arr) { // how to do the conversion? var objT = ?? list1.Add(objT); } return list1; } Any idea?

  • A quick design question about C++ container classes in shared memory

    - by recipriversexclusion
    I am writing a simple wrapper around boost::interprocess's vector container to implement a ring buffer in shared memory (shm) for IPC. Assume that buf is an instance of RingBuffer created in shm. Now, in its ctor, buf itself allocates a private boost::interprocess::vector data member to store values, e.g. m_data. My question is: I think m_data should also be created in shared memory. But it this a necessity? What happens if buf that was created in shm itself, allocates standard memory, i.e. using new. Does this get allocated on the calling process's heap? I don't think buf is allocated there so how come a data member that is private to an object not on a process's heap gets allocated there. I'm confused.

  • LinqDataSource wizard table list is not refreshing after updating LinqToSql classes

    - by dotnet_learner
    I have changed my dbml file like this. I have deleted all the tables and stored procs. I added new tables and stored procs from a new database. In the code-behind, I can access the new tables and stored procs. However, in the LinqDataSource using the same dbContext when I'm trying to configure the LinqDataSource. I can see all the old tables in the wizard drop-down. How to refresh the the wizard drop-down so that I can select the newly added tables? Deleting the old LinqDataSourceand adding a new one is not working.

  • Eclipse says I don't implement Enumeration, but I do

    - by Harm De Weirdt
    Goodmorning everybody, I'm having a little problem with a project for school. We are told to make an Iterator that implements Enumeration over a Hashmap. So i made this Enumeration: public Enumeration<Object> getEnumeration() { return new Enumeration<Object>() { private int itemsDone = 0; Collection<Long> keysCollection = getContent().keySet(); Long [] keys = keysCollection.toArray(new Long[keysCollection.size()]); @Override public boolean hasMoreElements() { if(itemsDone < getContent().size() +1 ) { return true; }else { return false; } } @Override public Object nextElement() { return getContent().get(keys[itemsDone++]); } }; } This goes in my Backpack class public class Backpack extends Item implements Carrier, Enumeration<Object>{ The hashmap is returned by getContent(). The problem now is that eclipse keeps telling me I havent implemented the methods from Enumeration. If I use the quick fix it just adds the hasMoreElements() and nextElement() dummy methods in my class. Somehow it doesn't see these methods in the inner class.. Can anyone help me please? Any help is appreciated.

  • Eclipse (Springsource Tool Suite 2.3.1) can't resolve dependencies for classes in the same package

    - by Steve
    This started happening when I upgraded my Springsource Toolsuite from 2.3 to 2.3.1. Essentially whenever I do anything, such as open a file, change a file, etc, I have to do a clean. Everything works fine when I do mvn commands on the command line, which leads me to believe that Eclipse is looking in the wrong place for compiled code or something along those lines, although that is entirely superstitious at this point. Example: I make a change to com.foo.mypackage.MyClass. Suddenly a bunch of tests that excercise MyClass get the red x - for class not found! In src/main/test: com.foo.DbUnitTest com.foo.mypackage.FooTest extends DbUnitTest DbUnitTest gets a class not found. I do a clean, and everything is fine. I touch something, and it breaks again :(. I don't really know where to begin on how to troubleshoot this.

  • Accessing the Custom Object Return type from ojdbc6 JDBC Thin Drivers

    - by Andrew Harmel-Law
    I'm writing some JDBC code which calls a Oracle 11g PL/SQL procdedure which has a Custom Object return type. I can get the code to call the procedure, but how do I access the returned Custom Object to obtain it's contained values?. An example of my code calling the procedure is below: PLSQL Code: Procedure GetDataSummary (p_my_key IN KEYS.MY_KEY%TYPE, p_recordset OUT data_summary_tab, p_status OUT VARCHAR2); Java Code: String query = "begin manageroleviewdata.getdatasummary(?, ?, ?); end;"); CallableStatement stmt = conn.prepareCall(query); stmt.setInt(1, 83); stmt.registerOutParameter(2, OracleTypes.ARRAY, "DATA_SUMMARY_TAB"); stmt.registerOutParameter(3, OracleTypes.VARCHAR); stmt.execute(stmt); How do I get the result back fron this?

  • Overriding classes/functions from a .dll.

    - by Jeff
    Say I have class A and class B. B inherits from class A, and implements a few virtual functions. The only problem is that B is defined in a .dll. Right now, I have a function that returns an instance of class A, but it retrieves that from a static function in the .dll that returns an instance of class B. My plan is to call the created object, and hopefully, have the functions in the .dll executed instead of the functions defined in class A. For some reason, I keep getting restricted memory access errors. Is there something I don't understand that will keep this plan from working?

  • ASP Calendar control returns Date type but I need Datetime to insert into SQL Server 2005

    - by rafael
    Hello, I am using a ASP Calendar control to insert a datetime value into a field to be part of an insert to a SQL Server 2005 db table. I get the following error when i submit the form to server and try to insert into table: [ArgumentException: The version of SQL Server in use does not support datatype 'date'.] Seems like Calendar control returns a Date type value. How could i make the Calendar control return a Datetime value instead? I know now that SQL Server 2005 does not support Date type fields.

    I am working on x86_64 machine. My linux kernel is also 64 bit kernel. As there are different ways to implement a system call (int 80, syscall, sysenter), i wanted to know what type of system call my machine is using. I am newbie to linux. I have written a demo program. include int main() { getpid(); return 0; } getpid() does one system call. Can anybody give me a method to find which type of system call will be used by my machine for this program.. Thank you....

  • Why cant partial methods be public if the implementation is in the same assembly?

    - by Simon
    According to this http://msdn.microsoft.com/en-us/library/wa80x488.aspx "Partial methods are implicitly private" So you can have this // Definition in file1.cs partial void Method1(); // Implementation in file2.cs partial void Method1() { // method body } But you cant have this // Definition in file1.cs public partial void Method1(); // Implementation in file2.cs public partial void Method1() { // method body } But why is this? Is there some reason the compiler cant handle public partial methods?

  • Entity framework error: The conversion of a datetime2 data type to a datetime data

    - by EdenMachine
    I know there are a ton of posts about this issue but none of them seem to solve my problem. Here's the scenario: I have a CreateDate DateTime column in my MS SQL Server database User table that is non-nullable and is automatically set using GetDate() method in "Default Value or Binding" setting. I am able to create a User just fine with the standard EF Insert but when I try to update the user, I get this error: The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value. What is the trick to not having the EF worry about the CreateDate column for updates? I have the StoreGenerationPattern = Identity but that isn't helping. Here are the EF properties for my Entity Property: http://screencast.com/t/8ndQRn9N And here is my Update method: http://screencast.com/t/UXIzhkhR

  • Calling function using 'new' is less expensive than without it?

    - by Matthew Taylor
    Given this very familiar model of prototypal construction: function Rectangle(w,h) { this.width = w; this.height = h; } Rectangle.prototype.area = function() { return this.width * this.height; }; Can anyone explain why calling "new Rectangle(2,3)" is consistently 10x FASTER than calling "Rectangle(2,3)" without the 'new' keyword? I would have assumed that because new adds more complexity to the execution of a function by getting prototypes involved, it would be slower. Example: var myTime; function startTrack() { myTime = new Date(); } function stopTrack(str) { var diff = new Date().getTime() - myTime.getTime(); println(str + ' time in ms: ' + diff); } function trackFunction(desc, func, times) { var i; if (!times) times = 1; startTrack(); for (i=0; i<times; i++) { func(); } stopTrack('(' + times + ' times) ' + desc); } var TIMES = 1000000; trackFunction('new rect classic', function() { new Rectangle(2,3); }, TIMES); trackFunction('rect classic (without new)', function() { Rectangle(2,3); }, TIMES); Yields (in Chrome): (1000000 times) new rect classic time in ms: 33 (1000000 times) rect classic (without new) time in ms: 368 (1000000 times) new rect classic time in ms: 35 (1000000 times) rect classic (without new) time in ms: 374 (1000000 times) new rect classic time in ms: 31 (1000000 times) rect classic (without new) time in ms: 368

  • PNGs alpha transparancy in AS3 - Unknown file-type

    - by WiseDonkey
    Hello there! After whittling down of the options we've encountered a problem with PNG's and ActionScript 3 (AS3). When loading a PNG 8 or PNG 32 with alpha transparancy we're getting the following error reported in Flash:- "Error #2124: Loaded file is an unknown type" Now, we're dealing with some legacy images, and it appears as though this problem isn't universal - some images believed to be 32bit alpha PNG are loading. BUT, some conclusions:- converting one image that was 32 bit alpha (NOT WORKING IN AS3) to PNG 8 index transparency DID work. And converting that same image to PNG 8 alpha DID NOT work. These all worked in AS2 There is no difference between the headers Headers of a Failing Image [0] => HTTP/1.1 200 OK [1] => Date: Tue, 06 Apr 2010 14:17:28 GMT [2] => Server: Apache/2.2.3 (Red Hat) [3] => Last-Modified: Tue, 06 Apr 2010 13:44:05 GMT [4] => ETag: "3700054-11d6-a3983340" [5] => Accept-Ranges: bytes [6] => Content-Length: 4566 [7] => Connection: close [8] => Content-Type: image/png Headers of a Working Image [0] => HTTP/1.1 200 OK [1] => Date: Tue, 06 Apr 2010 14:19:02 GMT [2] => Server: Apache/2.2.3 (Red Hat) [3] => Last-Modified: Fri, 30 Oct 2009 18:38:08 GMT [4] => ETag: "ba8057-65f2-5445c400" [5] => Accept-Ranges: bytes [6] => Content-Length: 26098 [7] => Connection: close [8] => Content-Type: image/png Any thoughts of a direction of further investigation or thoughts on a bewildering problem with little to no documentation; very warmly welcomed. EDIT Now it would appear as though something in the PHP conversion of the images is shafting; I use the following PHP to add alpha layers:- imagealphablending($image_p, false); ImageSaveAlpha($image_p, true); ImageFill($image_p, 0, 0, IMG_COLOR_TRANSPARENT);

  • Dynamically writing page titles and active classes with php

    - by toomanyairmiles
    For some time now I've been using the following code to dynamically write in html page titles and add an active class to menu items. Is this still a good why to achieve this or are there better/smarter/optimal ways of achieving the same thing? <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='contact.php'? 'class="active"' : '');?> Menu example <ul id="nav"> <li><a href="index.php" target="_parent" <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='index.php'? 'class="active"' : '');?>><span>Home</span></a></li> <li><a href="services.php" target="_parent" <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='services.php'?

  • Cast from Void* to TYPE* using C++ style cast: static_cast or reinterpret_cast

    - by David Relihan
    So if your converting from Void* to Type* or from Type* to Void* should you use: void func(void *p) { Params *params = static_cast<Params*>(p); } or void func(void *p) { Params *params = reinterpret_cast<Params*>(p); } To me static_cast seems the more correct but I've seen both used for the same purpose. Also, does the direction of the conversion matter. i.e. should I still use static_cast for: _beginthread(func,0,static_cast<void*>(params) I have read the other questions on C++ style casting but I'm still not sure what the correct way is for this scenario (I think it is static_cast)

  • Why can't sub-packages see package private classes?

    - by Polaris878
    Okay so, I have this project structure: package A.B class SuperClass (this class is marked package private) package A.B.C class SubClass (inherits from super class) I'd rather not make SuperClass publicly visible... It is really just a utility class for this specific project (A.B). It seems to me that SubClass should be able to see SuperClass, because package A.B.C is a subpackage of A.B... but this is not the case. What would be the best way to resolve this issue? I don't think it makes sense to move everything in A.B.C up to A.B or move A.B down to A.B.C... mainly because there will probably be an A.B.D which inherits from stuff in A.B as well... I'm a bit new to Java, so be nice :D (I'm a C++ and .NET guy)

  • Can I expose only a portion of one .NET DLL's public classes via a different "API" DLL?

    - by Ben McIntosh
    I am designing a WPF application that uses a DLL with maybe 40 public classes. I need these to be public for a variety of reasons including ease of data binding and obfuscation. I would like to allow other people to use only a portion of these classes as an API for my software. I thought I would create the main library (core.dll) and an API library (coreAPI.dll) with the API DLL to be referenced in a new project. Is there a way to allow coreAPI.dll to expose only a few of the classes that exist in core.dll? It's not so much a security issue as I primarily want to simply hide some of the unwanted classes from the Visual Studio Intellisense. Again, internal classes for the ones I want to hide is not really an option because I need to data bind some of these classes in WPF and for that, they must be public. Are there any other ways of doing this?
