  • STOP Application Pool Issue Programitically IIS7

    - by Sumit Kute
    In my application I needs to stop a application pool programmitically in IIS 7. I have created a local acccount and given him Administrative Priviledges. Here is the code Private static void StopApplication() { string serviceHostDeploymentType = "local"; if (serviceHostDeploymentType.Equals("local")) { WindowsIdentityImpersonate newIdentity = new WindowsIdentityImpersonate(); if (newIdentity.Impersonate("AccountName", Environment.MachineName, "Password")) { try { ServerManager serverManager = ServerManager.OpenRemote("Server"); string siteName = GetWebSiteNameById(serverManager, 1); Site parentWebsite = serverManager.Sites[siteName]; if (parentWebsite != null) { ApplicationPool apppool = serverManager.ApplicationPools["Application Pool Name"]; if (apppool != null) { apppool.Stop(); } } } finally { newIdentity.Undo(); } } } else { throw new ConfigurationErrorsException("..."); } } I am getting an error Access is denied.

  • Is this a bug? : I get " The type ... is not a complex type or an entity type" in my WCF data servic

    - by veertien
    When invoking a query on the data service I get this error message inside the XML feed: <m:error> <m:code></m:code> <m:message xml:lang="nl-NL">Internal Server Error. The type 'MyType' is not a complex type or an entity type.</m:message> </m:error> When I use the example described here in the article "How to: Create a Data Service Using the Reflection Provider (WCF Data Services)" http://msdn.microsoft.com/en-us/library/dd728281(v=VS.100).aspx it works as expected. I have created the service in a .NET 4.0 web project. My data context class returns a query object that is derived from the LINQExtender (http://linqextender.codeplex.com/). When I execute the query object in a unit test, it works as expected. My entity type is defined as: [DataServiceKey("Id")] public class Accommodation { [UniqueIdentifier] [OriginalFieldName("EntityId")] public string Id { get; set; } [OriginalFieldName("AccoName")] public string Name { get; set; } } (the UniqueIdentifier and OriginalFieldName attributes are used by LINQExtender) Does anybody know if this is a bug in WCF data services or am I doing something wrong?

  • Rails - difference between config.cache_store and config.action_controller.cache_store?

    - by gsmendoza
    If I set this in my environment config.action_controller.cache_store = :mem_cache_store ActionController::Base.cache_store will use a memcached store but Rails.cache will use a memory store instead: $ ./script/console >> ActionController::Base.cache_store => #<ActiveSupport::Cache::MemCacheStore:0xb6eb4bbc @data=<MemCache: 1 servers, ns: nil, ro: false>> >> Rails.cache => #<ActiveSupport::Cache::MemoryStore:0xb78b5e54 @data={}> In my app, I use Rails.cache.fetch(key){ object } to cache objects inside my helpers. All this time, I assumed that Rails.cache uses the memcached store so I'm surprised that it uses memory store. If I change the cache_store setting in my environment to config.cache_store = :mem_cache_store both ActionController::Base.cache_store and Rails.cache will now use the same memory store, which is what I expect: $ ./script/console >> ActionController::Base.cache_store => #<ActiveSupport::Cache::MemCacheStore:0xb7b8e928 @data=<MemCache: 1 servers, ns: nil, ro: false>, @middleware=#<Class:0xb7b73d44>, @thread_local_key=:active_support_cache_mem_cache_store_local_cache> >> Rails.cache => #<ActiveSupport::Cache::MemCacheStore:0xb7b8e928 @data=<MemCache: 1 servers, ns: nil, ro: false>, @middleware=#<Class:0xb7b73d44>, @thread_local_key=:active_support_cache_mem_cache_store_local_cache> However, when I run the app, I get a "marshal dump" error in the line where I call Rails.cache.fetch(key){ object } no marshal_dump is defined for class Proc Extracted source (around line #1): 1: Rails.cache.fetch(fragment_cache_key(...), :expires_in => 15.minutes) { ... } vendor/gems/memcache-client-1.8.1/lib/memcache.rb:359:in 'dump' vendor/gems/memcache-client-1.8.1/lib/memcache.rb:359:in 'set_without_newrelic_trace' What gives? Is Rails.cache meant to be a memory store? Should I call controller.cache_store.fetch in the places where I call Rails.cache.fetch?

  • Why is "Fixup" needed for Persistence Ignorant POCO's in EF 4?

    - by Eric J.
    One of the much-anticipated features of Entity Framework 4 is the ability to use POCO (Plain Old CLR Objects) in a Persistence Ignorant manner (i.e. they don't "know" that they are being persisted with Entity Framework vs. some other mechanism). I'm trying to wrap my head around why it's necessary to perform association fixups and use FixupCollection in my "plain" business object. That requirement seems to imply that the business object can't be completely ignorant of the persistence mechanism after all (in fact the word "fixup" sounds like something needs to be fixed/altered to work with the chosen persistence mechanism). Specifically I'm referring to the Association Fixup region that's generated by the ADO.NET POCO Entity Generator, e.g.: #region Association Fixup private void FixupImportFile(ImportFile previousValue) { if (previousValue != null && previousValue.Participants.Contains(this)) { previousValue.Participants.Remove(this); } if (ImportFile != null) { if (!ImportFile.Participants.Contains(this)) { ImportFile.Participants.Add(this); } if (ImportFileId != ImportFile.Id) { ImportFileId = ImportFile.Id; } } } #endregion as well as the use of FixupCollection. Other common persistence-ignorant ORMs don't have similar restrictions. Is this due to fundamental design decisions in EF? Is some level of non-ignorance here to stay even in later versions of EF? Is there a clever way to hide this persistence dependency from the POCO developer? How does this work out in practice, end-to-end? For example, I understand support was only recently added for ObservableCollection (which is needed for Silverlight and WPF). Are there gotchas in other software layers from the design requirements of EF-compatible POCO objects?

  • Factory pattern vs ease-of-use?

    - by Curtis White
    Background, I am extending the ASP.NET Membership with custom classes and extra tables. The ASP.NET MembershipUser has a protected constructor and a public method to read the data from the database. I have extended the database structure with custom tables and associated classes. Instead of using a static method to create a new member, as in the original API: I allow the code to instantiate a simple object and fill the data because there are several entities. Original Pattern #1 Protected constructor > static CreateUser(string mydata, string, mydata, ...) > User.Data = mydata; > User.Update() My Preferred Pattern #2 Public constructor > newUser = new MembershipUser(); > newUser.data = ... > newUser.ComplextObject.Data = ... > newUser.Insert() > newUser.Load(string key) I find pattern #2 to be easier and more natural to use. But method #1 is more atomic and ensured to contain proper data. I'd like to hear any opinions on pros/cons. The problem in my mind is that I prefer a simple CRUD/object but I am, also, trying to utilize the underlying API. These methods do not match completely. For example, the API has methods, like UnlockUser() and a readonly property for the IsLockedOut

  • simpletest - Why does setReturnValue() seem to change behaviour depending on if test is run in isola

    - by JW
    I am using SimpleTest version 1.0.1 for a unit test. I create a new mock object within a test method and on it i do: $MockDbAdaptor->setReturnValue('query',1); Now, when i run this in a standalone unit test my tested object is happy to see 1 returned when query() is called on the mock db adaptor. However, when this exact same test is run as part of my 'all_tests' TestSuite, the test is failing. This happens because a call to the mock's query() method does not appear to return any value - thus causing my test subject to complain and trigger an unexpected exception that fails the test. So, the behaviour of setReturnValue() seems to change depending on whether the test is run in isolation or not. I can get it to work in both a standalone and TestSuite contexts by using this instead: $MockDbAdaptor->setReturnValueAt(0,'query',1); So my immediate problem can be fixed ...but it feels like a hack. I thought if i create a new mock within a test method then why is the setReturnValue() behaviour getting affected by the context in which the test class instance is run? It feel like a bug.

  • - (void)keyboardWasShown not called when switching to another UITextField

    - by Shawn
    I'm having a strange problem that I don't understand. I have a UIScrollView with several UITextField objects. When I switch to the view, I set the first UITextField as firstresponder, and the keyboardWasShown method gets called due to the UIKeyboardDidShowNotification that the view is registered for. The weird thing is, when I touch the next UITextField, the keyboardWasShown method is not called. I don't understand this, since Apple's documentation says "If your interface has multiple text fields, the user can tap between them to edit the values in each one. When that happens, however, the keyboard does not disappear but the system does still generate UIKeyboardDidShowNotification notifications each time editing begins in a new text field." My code I've copied directly from Apple's documentation as well, and it works properly, but it only gets called the first time. What am I missing? - (void)registerForKeyboardNotifications { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardDidShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasHidden:) name:UIKeyboardDidHideNotification object:nil]; } - (void)keyboardWasShown:(NSNotification *)aNotification { //if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; CGSize kbSize = [[info objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue].size; CGRect bkgndRect = activeField.superview.frame; bkgndRect.size.height += kbSize.height; [activeField.superview setFrame:bkgndRect]; [scrollView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y) animated:YES]; keyboardShown = YES; UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; }

  • How can you assign multiple Javascript functions to the upload_start_handler for WordPress's SWFUplo

    - by Byron
    I've got 2 WordPress plugins (PhotoSmash and TwitPic-It) that need to hook into the SWFUploader for the Media Uploader in WordPress. SWFUpload has a setting "upload_start_handler" where you can specify a javascript function that will run immediately before the upload begins. The trouble is that I need to assign 2 different functions to run in separate plugins that may or may not coexist in a given user's WordPress blog. I want to make the implementation so that it allows other plugin authors to hook their own javascript functions. I don't know that I have access to the actual event being fired. The "upload_start_handler" is a setting on a JS object, not an event hook on the flash object. You set it like: swfu.settings.upload_start_handler = function(){ runFlashStartUploadFunctions(); } My current plan is to add a 2 functions and an array variable (check if they exists first). The array variable is intended to hold an array of function names (strings) to run when "runFlashStartUploadFunctions" gets called at upload start. The first function is to add new functions to the array. The second function is "runFlashStartUploadFunctions", and it will iterate through the array and eval each function name. Is there a better way? Thanks, Byron

  • What are some Java memory management best practices?

    - by Ascalonian
    I am taking over some applications from a previous developer. When I run the applications through Eclipse, I see the memory usage and the heap size increase a lot. Upon further investigation, I see that they were creating an object over-and-over in a loop as well as other things. I started to go through and do some clean up. But the more I went through, the more questions I had like "will this actually do anything?" For example, instead of declaring a variable outside the loop mentioned above and just setting its value in the loop... they created the object in the loop. What I mean is: for(int i=0; i < arrayOfStuff.size(); i++) { String something = (String) arrayOfStuff.get(i); ... } versus String something = null; for(int i=0; i < arrayOfStuff.size(); i++) { something = (String) arrayOfStuff.get(i); } Am I incorrect to say that the bottom loop is better? Perhaps I am wrong. Also, what about after the second loop above, I set "something" back to null? Would that clear out some memory? In either case, what are some good memory management best practices I could follow that will help keep my memory usage low in my applications? Update: I appreciate everyones feedback so far. However, I was not really asking about the above loops (although by your advice I did go back to the first loop). I am trying to get some best practices that I can keep an eye out for. Something on the lines of "when you are done using a Collection, clear it out". I just really need to make sure not as much memory is being taken up by these applications.

  • Opened SerialPort crashes C# application

    - by Stefan Teitge
    The computer is connected to measuring device via a physical COM1. I have simple form where I open a serial port, tell the device that I'm alive and occasionally the device sends data. (every some minutes) Thread _readThread = new Thread(Read); SerialPort _serialPort = new SerialPort("COM1", 9600); _serialPort.Parity = Parity.None; _serialPort.DataBits = 8; _serialPort.StopBits = StopBits.One; _serialPort.Handshake = Handshake.None; _serialPort.DtrEnable = true; _serialPort.Open(); _readThread.Start(); _serialPort.Write("#listening"); The read function (which works): public void Read() { string message = _serialPort.ReadLine(); } After approximately one minute the application crashes (even while debugging). It reports an ObjectDisposedException (for the underlying stream?). The message tells that the SafeHandle was closed. Stack strace is below: at Microsoft.Win32.UnsafeNativeMethods.GetOverlappedResult(SafeFileHandle hFile, NativeOverlapped lpOverlapped, Int32& lpNumberOfBytesTransferred, Boolean bWait) at System.IO.Ports.SerialStream.EventLoopRunner.WaitForCommEvent() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()* Any ideas? The problem is reported widely but usually involve the device beeing physically detached from the PC.

  • ASP.NET/C# - Deserialize XML, XSD.exe created multiple classes

    - by Barryman9000
    I'm trying to deserialize some XML (returned from a web service) into an object that I created using XSD.exe. The XSD executable created a .CS file with a different partial class for each parent node in the XML. For Example, the beginning of the XML looks like this (why can't I post xml here? sorry, this is ugly): <disclaimer><notificationDescription>Additional charges will apply.</notificationDescription></disclaimer><quote><masterQuote></masterQuote></quote> And the Class generated by the XSD.exe has a partial class named disclaimer with a get; set; string for notificationDescription. And another partial class for quoteMasterQuote with the corresponding child nodes as public strings. How can I deserialize this XML file into multiple classes? I found this code, but it seems like it'll only work for one object. public static PricingResponse2 DeSerialize(string _xml) { PricingResponse2 _resp = new PricingResponse2(); StringReader _strReader = new StringReader(_xml); XmlSerializer _serializer = new XmlSerializer(_resp.GetType()); XmlReader _xmlReader = new XmlTextReader(_strReader); try { _resp = (PricingResponse2)_serializer.Deserialize(_xmlReader); return _resp; } catch (Exception ex) { string _error = ex.Message; throw; } finally { _xmlReader.Close(); _strReader.Close(); _strReader.Dispose(); } } This is the first time I've tried this, so I'm a little lost.

  • Odd difference between Python 2.5 and Python 2.6 on MacOS 10.6 using ctypes and libproc proc_pidinfo

    - by cemasoniv
    I'm trying to determine the current working directory of a process given its PID. The command-line utility lsof does something similar. Here's the source to the python script: import ctypes from ctypes import util import sys PROC_PIDVNODEPATHINFO = 9 proc = ctypes.cdll.LoadLibrary(util.find_library("libproc")) print(proc.proc_pidinfo) class vnode_info(ctypes.Structure): _fields_ = [('data', ctypes.c_ubyte * 152)] class vnode_info_path(ctypes.Structure): _fields_ = [('vip_vi', vnode_info), ('vip_path', ctypes.c_char * 1024)] class proc_vnodepathinfo(ctypes.Structure): _fields_ = [('pvi_cdir', vnode_info_path), ('pvi_rdir', vnode_info_path)] inst = proc_vnodepathinfo() pid = int(sys.argv[1]) ret = proc.proc_pidinfo( pid, PROC_PIDVNODEPATHINFO, 0, ctypes.byref(inst), ctypes.sizeof(inst) ) print(ret, inst.pvi_cdir.vip_path) However, even though this script behaves as expected on Python 2.6, it does not work in Python 2.5: host:dir user$ sudo /usr/bin/python2.6 script.py 2698 <_FuncPtr object at 0x100419ae0> (2352, '/') host:dir user$ sudo /usr/bin/python2.5 script.py 2698 <_FuncPtr object at 0x19fdc0> (0, '') (PID 2698 is "Activity Monitor.app"). Note the different return values. Since this program strongly based on ctypes, I can't imagine any difference in Python itself that would cause this. The same behavior (as Python 2.5) occurs with my self-built Python 3.2. I'm not sure what versioning information I can give to help track down the weirdness -- or even come up with a solution for 2.5 -- but here's some stuff: host:dir user$ otool -L /usr/bin/python2.6 /usr/bin/python2.6: /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.0) host:dir user$ otool -L /usr/bin/python2.5 /usr/bin/python2.5 (architecture i386): /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.0) /usr/bin/python2.5 (architecture ppc7400): /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.0) host:dir user$ uname -a Darwin host.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386 Thanks to anyone that has a clue about what's going on here:)

  • C# How to find if an event is hooked up

    - by Nick
    I want to be able to find out if an event is hooked up or not. I've looked around, but I've only found solutions that involved modifying the internals of the object that contains the event. I don't want to do this. Here is some test code that I thought would work: // Create a new event handler that takes in the function I want to execute when the event fires EventHandler myEventHandler = new EventHandler(myObject_SomeEvent); // Get "p1" number events that got hooked up to myEventHandler int p1 = myEventHandler.GetInvocationList().Length; // Now actually hook an event up myObject.SomeEvent += m_myEventHandler; // Re check "p2" number of events hooked up to myEventHandler int p2 = myEventHandler.GetInvocationList().Length; Unfort the above is dead wrong. I thought that somehow the "invocationList" in myEventHandler would automatically get updated when I hooked an event to it. But no, this is not the case. The length of this always comes back as one. Is there anyway to determine this from outside the object that contains the event?

  • Gridview empty when SelectedIndexChanged called

    - by xan
    I have a DataGrid which is being bound dynamically to a database query. The user enters some search text into a text field, clicks search, and the code behind creates the appropriate database query using LINQ (searches a table based on the string and returns a limited set of the columns). It then sets the GridView datasource to be the query and calls DataBind(). protected void btnSearch_Click(object sender, EventArgs e) { var query = from record in DB.Table where record.Name.Contains(txtSearch.Text) //Extra string checking etc. removed. select new { record.ID, record.Name, record.Date }; gvResults.DataSource = query; gvResults.DataBind(); } This works fine. When a user selects a row in the grid, the SelectedIndexChanged event handler gets the id from the row in the grid (one of the fields), queries the full record from the DB and then populates a set of editor / details fields with the records full details. protected void gvResults_SelectedIndexChanged(object sender, EventArgs e) { int id = int.Parse(gvResults.SelectedRow.Cells[1].Text); DisplayDetails(id); } This works fine on my local machine where I'm developing the code. On the production server however, the function is called successfully, but the row and column count on gvResults, the GridVeiw is 0 - the table is empty. The GridView's viewstate is enabled and I can't see obvious differences. Have I made some naive assumptions, or am I relying on something that is likely to be configured differently in debug? Locally I am running an empty asp.net web project in VS2008 to make development quicker. The production server is running the sitecore CMS so is configured rather differently. Any thoughts or suggestions would be most welcome. Thanks in advance!

  • C# - InvalidCastException when fetching double from sqlite

    - by Irro
    I keep getting a InvalidCastException when I'm fetching any double from my SQLite database in C#. The exception says "Specified cast is not valid." I am able to see the value in a SQL manager so I know it exists. It is possible to fetch Strings (VARCHARS) and ints from the database. I'm also able to fetch the value as an object but then I get "66.0" when it's suppose to be "66,8558604947586" (latitude coordination). Any one who knows how to solve this? My code: using System.Data.SQLite; ... SQLiteConnection conn = new SQLiteConnection(@"Data Source=C:\\database.sqlite; Version=3;"); conn.Open(); SQLiteDataReader reader = getReader(conn, "SELECT * FROM table"); //These are working String name = reader.GetString(1); Int32 value = reader.GetInt32(2); //This is not working Double latitude = reader.getDouble(3); //This gives me wrong value Object o = reader[3]; //or reader["latitude"] or reader.getValue(3)

  • Dynamically loading sub-trees into YUI Treeview

    - by user319399
    When you create a YUI TreeView instance, you can pass in an object that represents an entire tree, and it will automatically build up the TextNodes for you. I'd like to send in a partial tree, such that the tree only goes, say, 2 levels deep, and anything deeper than that will invoke dynamic loading. I've got that much working. Now for the interesting part. In the dynamic loading callback I give to my tree instance, I want to again be able to just give YUI a big object representing more of the tree. I want to do something like this: // data is a array of objects organized into a tree, with some nodes requiring dynamic loading when they are navigated to tree = new YAHOO.widget.TreeView("treeDiv1", data); tree.setDynamicLoad(loadDataForNode); function loadDataForNode(node, onCompleteCallback) { if(node.children.length==0) { var subTree = { "label":"Cars", isLeaf:false, children:[ { "label":"Chevy", isLeaf:true }, { "label":"Ford", isLeaf:true }, ] }; // doesn't work, even though it has the required "label" field var tempNode = new YAHOO.widget.TextNode(subTree, node, true); } onCompleteCallback(); } Is this possible? Or do I have to iterate over all the nodes in my subtree and construct individual TextNodes for each one? Thanks much...

  • Java JUnit: The method X is ambiguous for type Y

    - by Rosarch
    I had some tests working fine. Then, I moved it to a different package, and am now getting errors. Here is the code: import static org.junit.Assert.*; import java.util.HashSet; import java.util.Map; import java.util.Set; import org.jgrapht.Graphs; import org.jgrapht.WeightedGraph; import org.jgrapht.graph.DefaultWeightedEdge; import org.jgrapht.graph.SimpleWeightedGraph; import org.junit.*; @Test public void testEccentricity() { WeightedGraph<String, DefaultWeightedEdge> g = generateSimpleCaseGraph(); Map<String, Double> eccen = JGraphtUtilities.eccentricities(g); assertEquals(70, eccen.get("alpha")); assertEquals(80, eccen.get("l")); assertEquals(130, eccen.get("l-0")); assertEquals(100, eccen.get("l-1")); assertEquals(90, eccen.get("r")); assertEquals(120, eccen.get("r-0")); assertEquals(130, eccen.get("r-1")); } The error message is this: The method assertEquals(Object, Object) is ambiguous for the type JGraphtUtilitiesTest How can I fix this? Why did this problem occur as I moved the class to a different package?

  • Class Decorators, Inheritence, super(), and maximum recursion

    - by jamstooks
    I'm trying to figure out how to use decorators on subclasses that use super(). Since my class decorator creates another subclass a decorated class seems to prevent the use of super() when it changes the className passed to super(className, self). Below is an example: def class_decorator(cls): class _DecoratedClass(cls): def __init__(self): return super(_DecoratedClass, self).__init__() return _DecoratedClass class BaseClass(object): def __init__(self): print "class: %s" % self.__class__.__name__ def print_class(self): print "class: %s" % self.__class__.__name__ bc = BaseClass().print_class() class SubClass(BaseClass): def print_class(self): super(SubClass, self).print_class() sc = SubClass().print_class() @class_decorator class SubClassAgain(BaseClass): def print_class(self): super(SubClassAgain, self).print_class() sca = SubClassAgain() # sca.print_class() # Uncomment for maximum recursion The output should be: class: BaseClass class: BaseClass class: SubClass class: SubClass class: _DecoratedClass Traceback (most recent call last): File "class_decorator_super.py", line 34, in <module> sca.print_class() File "class_decorator_super.py", line 31, in print_class super(SubClassAgain, self).print_class() ... ... RuntimeError: maximum recursion depth exceeded while calling a Python object Does anyone know of a way to not break a subclass that uses super() when using a decorator? Ideally I'd like to reuse a class from time to time and simply decorate it w/out breaking it.

  • Flash/Flex: "Warning: filter will not render" problem

    - by davidemm
    In my flex application, I have a custom TitleWindow that pops up in modal fashion. When I resize the browser window, I get this warning: Warning: Filter will not render. The DisplayObject’s filtered dimensions (1286, 107374879) are too large to be drawn. Clearly, I have nothing set with a height of 107374879. After that, any time I mouse over anything in the Flash Player (v. 10), the CPU churns at 100%. When I close the TitleWindow, the problem subsides. Sadly, the warning doesn't seem to indicate which DisplayObject object is too large to draw. I've tried attaching explicit height/widths to the TitleWindow and the components within, but still no luck. [Edit] The plot thickens: I found that the problem only occures when I set the PopUpManager's createPopUp modal parameter to "true." I don't see the behavior when modal is set to "false." It's failing while applying the graying filter to other components that comes from being modal. Any ideas how I can track down the one object that has not been initialized but is being filter during the modal phase? Thanks for reading.

  • What should be the responsibility of a presenter here?

    - by Achu
    I have a 3 layer design. (UI / BLL / DAL) UI = ASP.NET MVC In my view I have collection of products for a category. Example: Product 1, Product 2 etc.. A user able to select or remove (by selecting check box) product’s from the view, finally save as a collection when user submit these changes. With this 3 layer design how this product collection will be saved? How the filtering of products (removal and addition) to the category object? Here are my options. (A) It is the responsibility of the controller then the pseudo Code would be Find products that the user selected or removed and compare with existing records. Add or delete that collection to category object. Call SaveCategory(category); // BLL CALL Here the first 2 process steps occurs in the controller. (B) It is the responsibility of BLL then pseudo Code would be Collect products what ever user selected SaveCategory(category, products); // BLL CALL Here it's up to the SaveCategory (BLL) to decide what products should be removed and added to the database. Thanks

  • How to access attributes using Nokogiri

    - by Liz
    I have a simple task of accessing the values of some attributes. Below is a simple script that uses Nokogiri::XML::Builder to create a simple xml doc. require 'nokogiri' builder = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml| xml.Placement(:messageId => "392847-039820-938777", :system => "MOD", :version => "2.0") { xml.objects { xml.object(:myattribute => "99", :anotherattrib => "333") xml.nextobject_ '9387toot' xml.Entertainment "Last Man Standing" } } end puts builder.to_xml puts builder.root.attributes["messageId"] The results are below: <?xml version="1.0" encoding="UTF-8"?> <Placement messageId="392847-039820-938777" version="2.0" system="MOD"> <objects> <object anotherattrib="333" myattribute="99"/> <nextobject>9387toot</nextobject> <Entertainment>Last Man Standing</Entertainment> </objects> </Placement> C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/document.rb:178:in `add_child': Document already has a root node (RuntimeError) from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/node.rb:455:in `parent=' from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/builder.rb:358:in `insert' from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/builder.rb:350:in `method_missing' from C:/Documents and Settings/etrojan/workspace/Lads/tryXPATH2.rb:15 The xml that is generated looks fine. However, my attempts to access attributes cause an error to be generated, "Document already has a root node". I don't understand why a puts statement would cause this error. Any suggestions would be greatly appreciated.

  • How to provide stl like container with public const iterator and private non-const iterator?

    - by WilliamKF
    Hello, I am deriving a class privately from std::list and wish to provide public begin() and end() for const_iterator and private begin() and end() for just plain iterator. However, the compiler is seeing the private version and complaining that it is private instead of using the public const version. I understand that C++ will not overload on return type (in this case const_iterator and iterator) and thus it is choosing the non-const version since my object is not const. Short of casting my object to const before calling begin() or not overloading the name begin is there a way to accomplish this? I would think this is a known pattern that folks have solved before and would like to follow suit as to how this is typically solved. class myObject; class myContainer : private std::list<myObject> { public: typedef std::list<myObject>::const_iterator myContainer::const_iterator; private: typedef std::list<myObject>::iterator myContainer::iterator; public: myContainer::const_iterator begin() const { return std::list<myObject>::begin(); } myContainer::const_iterator end() const { return std::list<myObject>::end(); } private: myContainer::iterator begin() { return std::list<myObject>::begin(); } myContainer::iterator end() { return std::list<myObject>::end(); } }; void myFunction(myContainer &container) { myContainer::const_iterator aItr = container.begin(); myContainer::const_iterator aEndItr = container.end(); for (; aItr != aEndItr; ++aItr) { const myObject &item = *aItr; // Do something const on container's contents. } } The error from the compiler is something like this: ../../src/example.h:447: error: `std::_List_iterator<myObject> myContainer::begin()' is private caller.cpp:2393: error: within this context ../../src/example.h:450: error: `std::_List_iterator<myObject> myContainer::end()' is private caller.cpp:2394: error: within this context Thanks. -William
