    Given: public class Thread1 { int x = 0; public class Runner implements Runnable { public void run() { int current = 0; for (int i = 0; i < 4; i++) { current = x; System.out.print(current + " "); x = current + 2; } } } public void go() { Runnable r1 = new Runner(); new Thread(r1).start(); new Thread(r1).start(); } public static void main(String[] args) { new Thread1().go(); } } Which two are possible results?

  • System.Drawing.Image for Images in Business Objects?

    - by Mudu
    Hi Folks I'd like to store an image in a business object. In MSDN I saw that the System.Drawing-namespace provides lots of GDI+-features, etc. Is it okay to store an Image in an System.Drawing.Image class in business layer (which is a class library "only"), and thus including a reference to System.Drawing too? I slightly feel just kind of bad doing that, 'cause it seems like I have UI-specific references in business code. Moreover, the code could become unnecessarily platform-dependant (though this is only a problem in theory, because we do not develop for multiple platforms). If it isn't right that way, which type would fit best? Thank you for any response! Matthias

  • C# Reflection - Casting private Object field

    - by alhazen
    I have the following classes: public class MyEventArgs : EventArgs { public object State; public MyEventArgs (object state) { this.State = state; } } public class MyClass { // ... public List<string> ErrorMessages { get { return errorMessages; } } } When I raise my event, I set 'State' of the MyEventArgs object to an object of type MyClass. I'm trying to retrieve ErrorMessages by reflection in my event handler: public static void OnEventEnded(object sender, EventArgs args) { Type type = args.GetType(); FieldInfo stateInfo = type.GetField("State"); PropertyInfo errorMessagesInfo = stateInfo.FieldType.GetProperty("ErrorMessages"); object errorMessages = errorMessagesInfo.GetValue(null, null); } But this returns errorMessagesInfo as null (even though stateInfo is not null). Is it possible to retrieve ErrorMessages ? Thank you

  • Help finding table cell using locator after tableCellAddress finds the cell

    - by Greg Weinman
    Hi All, I have a JSP page populated by javascript resulting in a typical table element cascade . After population I see the text I want using getTable("tableLister.listTable.1.1") The table also has a class=clsDisplayTableBody. I want to click the check box in column 0 for the row of interest. However, all of these tests fail isElementPresent("//*[text()="+cellContents+"]/../td[0]")) isElementPresent("//table[@class='clsDisplayTableBody']//tr[1]/td[0]")) isElementPresent("css='clsDisplayTableBody' tr:nth-child(1) td:nth-child(0)")) isElementPresent("//xpath=id('tableLister.listTable')/descendant::tr[1]/descendant::td[0]")) isElementPresent("//table[@id='tableLister.listTable']//tbody/tr[1]/td[0]")) isElementPresent("//table[@id='tableLister.listTable']//tr[1]/td[0]")) Is there anything else I could try?

  • My helper methods in controller

    - by FancyDancy
    My app should render html, to answer when a user clicks ajax-link. My controller: def create_user @user = User.new(params) if @user.save status = 'success' link = link_to_profile(@user) #it's my custom helper in Application_Helper.rb else status = 'error' link = nil end render :json => {:status => status, :link => link} end My helper: def link_to_profile(user) link = link_to(user.login, {:controller => "users", :action => "profile", :id => user.login}, :class => "profile-link") return(image_tag("/images/users/profile.png") + " " + link) end I have tried such methods: ApplicationController.helpers.link_to_profile(@user) # It raises: NoMethodError (undefined method `url_for' for nil:NilClass) and: class Helper include Singleton include ApplicationHelper include ActionView::Helpers::TextHelper include ActionView::Helpers::UrlHelper include ApplicationHelper end def help Helper.instance end help.link_to_profile(@user) # It also raises: NoMethodError (undefined method `url_for' for nil:NilClass) In addition, yes, I KNOW about :helper_method, and it works, but i don't want to overload my ApplicationController with a plenty of that methods

  • Of Datagridviews, databinding, and non validating cell values.

    - by Yanko Hernández Alvarez
    Lets simplify. Lets say I have this class: class T { public string Name { get; set; } public int Age { get; set; } public int height{ get; set; } ... } and I have a DataGridView's DataSource bound to a BindingList <T>, with N columns, each one bound to each property. I need to: Allow the user to enter non validating ages, heights, etc (for instance "aaa") Color the cells with non validating values (red background) Retain the non validating values displayed until the form is closed (I don't want to lose the values entered until the form is closed, so the user has the option to correct the bad cells anytime he wants BEFORE closing the form) Keep the last correct values entered for each cell with non validating values entered. When the form is closed, ditch the non validating values and keep the last correct values entered. Is there any easy way to do this?

  • Help with jQuery issue

    - by Espen Arnoy
    I have a simple page with a list if "items". I am allowing users to vote on these items, but I only want to allow the user to vote one per. item. Therefore i have made a jQuery script that adds a class to the items the user has voted on: if(! $(this).find(".item span").hasClass("voted")) { $(".item").hover(function() { $(this).find(".ratingbar").hide(); $(this).find(".votebar").show(); }, function() { $(this).find(".votebar").hide(); $(this).find(".ratingbar").show(); }); }; This is the script that prevents the user from voting again on the same item. $(".votebutton").click(function() { $("div#"+offerid).find(".item").addClass("voted"); } My problem is that this doesn´t work. When hovering an item, the hover function still runs even though the second script successfully added the class "voted" to the html. Why can this be?

  • NLB RPC server is unavailable on the specified computer

    - by Robin Weston
    Hi guys, Firstly, I'll admit that my networking knowledge is limited so as people request more information I'll update this question accordingly. I am trying to create a NLB Cluster across 2 Windows Server 2008 Web Servers. Neither of the machines are members of a domain, and both have 2 NICs (one for processing external web traffic, and one for communicating internally). I have installed NLB on both machines, and have created a cluster on Host A and added itself to it. However, when I try and add Host B (using the address from the external NIC) I get the following error : "The RPC server is unavailable on the specified computer". On Host B I can see that the RPC service is running fine. I can also ping and RDP from Host A to Host B with no problems either. I have disabled the windows firewall on both machines but that had no effect

  • Unexpected generics behaviour

    - by pronicles
    I found strange generics behaviour. In two words - thing I realy want is to use ComplexObject1 in most general way, and the thing I realy missed is why defined generic type(... extends BuisnessObject) is lost. The discuss thread is also awailable in my blog http://pronicles.blogspot.com/2010/03/unexpected-generics-behaviour.html. public class Test { public interface EntityObject {} public interface SomeInterface {} public class BasicEntity implements EntityObject {} public interface BuisnessObject<E extends EntityObject> { E getEntity(); } public interface ComplexObject1<V extends SomeInterface> extends BusinessObject<BasicEntity> {} public interface ComplexObject2 extends BuisnessObject<BasicEntity> {} public void test(){ ComplexObject1 complexObject1 = null; ComplexObject2 complexObject2 = null; EntityObject entityObject1 = complexObject1.getEntity(); //BasicEntity entityObject1 = complexObject1.getEntity(); wtf incompatible types!!!!

    I have the following class: template <typename Type = void> class AlignedMemory { public: AlignedMemory(size_t alignment, size_t size) : memptr_(0) { int iret(posix_memalign((void **)&memptr_, alignment, size)); if (iret) throw system_error("posix_memalign"); } virtual ~AlignedMemory() { free(memptr_); } operator Type *() const { return memptr_; } Type *operator->() const { return memptr_; } //operator Type &() { return *memptr_; } //Type &operator[](size_t index) const; private: Type *memptr_; }; And attempt to instantiate an automatic variable like this: AlignedMemory blah(512, 512); This gives the following error: src/cpfs/entry.cpp:438: error: missing template arguments before ‘buf’ What am I doing wrong? Is void not an allowed default parameter?

  • initWithCoder works, but init seems to be overwriting my objects properties?

    - by Zigrivers
    Hi guys, I've been trying to teach myself how to use the Archiving/Unarchiving methods of NSCoder, but I'm stumped. I have a Singleton class that I have defined with 8 NSInteger properties. I am trying to save this object to disk and then load from disk as needed. I've got the save part down and I have the load part down as well (according to NSLogs), but after my "initWithCoder:" method loads the object's properties appropriately, the "init" method runs and resets my object's properties back to zero. I'm probably missing something basic here, but would appreciate any help! My class methods for the Singleton class: + (Actor *)shareActorState { static Actor *actorState; @synchronized(self) { if (!actorState) { actorState = [[Actor alloc] init]; } } return actorState; } -(id)init { if (self = [super init]) { NSLog(@"New Init for Actor started...\nStrength: %d", self.strength); } return self; } -(id)initWithCoder:(NSCoder *)coder { if (self = [super init]) { strength = [coder decodeIntegerForKey:@"strength"]; dexterity = [coder decodeIntegerForKey:@"dexterity"]; stamina = [coder decodeIntegerForKey:@"stamina"]; will = [coder decodeIntegerForKey:@"will"]; intelligence = [coder decodeIntegerForKey:@"intelligence"]; agility = [coder decodeIntegerForKey:@"agility"]; aura = [coder decodeIntegerForKey:@"aura"]; eyesight = [coder decodeIntegerForKey:@"eyesight"]; NSLog(@"InitWithCoder executed....\nStrength: %d\nDexterity: %d", self.strength, self.dexterity); [self retain]; } return self; } -(void) encodeWithCoder:(NSCoder *)encoder { [encoder encodeInteger:strength forKey:@"strength"]; [encoder encodeInteger:dexterity forKey:@"dexterity"]; [encoder encodeInteger:stamina forKey:@"stamina"]; [encoder encodeInteger:will forKey:@"will"]; [encoder encodeInteger:intelligence forKey:@"intelligence"]; [encoder encodeInteger:agility forKey:@"agility"]; [encoder encodeInteger:aura forKey:@"aura"]; [encoder encodeInteger:eyesight forKey:@"eyesight"]; NSLog(@"encodeWithCoder executed...."); } -(void)dealloc { //My dealloc stuff goes here [super dealloc]; } I'm a noob when it comes to this stuff and have been trying to teach myself for the last month, so forgive anything obvious. Thanks for the help!

  • Sharepoint: Is it possible to automate the deployment of a custom CAS policy?

    - by user332133
    Hi all, I'm looking for a way to automate the deployment of a custom CAS policy in SharePoint. What i would like to achieve is the following: All assemblies that have been built and signed by our build server (with a secret key) should run in SharePoint under the 'higher than normal' trust level. Now I can manually edit the cas policy files to include something like this: <CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="MyPermissionSet" Name="[My Company public key]" Description="Grants all "> <IMembershipCondition class="StrongNameMembershipCondition" version="1" PublicKeyBlob="[public key goes here]" /> </CodeGroup> And that works great. However, we have several huge sharepoint farms, with many applications running on it. I'd like to avoid having to manually edit all policy files to include this xml snippet. Is there a way to automate this? For example, from a feature? With kind regards, Erwin van der Valk

  • for a single-table inheritance in rails, how do I know the 'type' when creating a record?

    - by Angela
    I have several models which are very similar: Contact_Emails, Contact_Letters, Contact_Calls -- and I think life could be easier making them into a Single Table Inheritance called Contact_Event. However, the way I have it set up now is when something is created for a Contact_Email, I have a dedicated controller that I call and know that I am passing the arguments that are approrpriate. For example, new_contact_email(contact, email). I then have: Emails.find(email.contact_id), etcera, all very specific to that Model. I'm not sure how I extract the class/models to use. For example, I currently have the following because I have separate controllers for each model: def do_event(contact, call_or_email_or_letter) model_name = call_or_email_or_letter.class.name.tableize.singularize link_to( "#{model_name.camelize}", send("new_contact_#{model_name}_path", :contact => contact, :status => 'done', :"#{model_name}" => call_or_email_or_letter ) ) end What I really want is to: link_to("#model_name.camelize}", send("new_contact_event_path(contact,call_or_email_or_letter)"

  • Setting generic type at runtime

    - by destroyer of evil
    I have a class public class A<T> { public static string B(T obj) { return TransformThisObjectToAString(obj); } } I can call the static function like this just fine on a known/specified type: string s= A<KnownType>.B(objectOfKnownType); How do I make this call, if I don't know T beforehand, rather I have a variable of type Type that holds the type. If I do this: Type t= typeof(string); string s= A<t>.B(someStringObject); I get this compiler error: Cannot implicitly convert type 't' to 'object'

  • How to force grails GORM to respect DB scheme ?

    I have two domains : class CodeSet { String id String owner String comments String geneRLF String systemAPF static hasMany = [cartridges:Cartridge] static constraints = { id(unique:true,blank:false) } static mapping = { table 'code_set' version false columns { id column:'code_set_id', generator: 'assigned' owner column:'owner' comments column:'comments' geneRLF column:'gene_rlf' systemAPF column:'system_apf' } } and : class Cartridge { String id String code_set_id Date runDate static belongsTo = CodeSet static constraints = { id(unique:true,blank:false) } static mapping = { table 'cartridge' version false columns { id column:'cartridge_id', generator: 'assigned' code_set_id column:'code_set_id' runDate column:'run_date' } } Actually, with those models, I get tables : - code_set, - cartridge, - and table : code_set_cartridge (two fields : code_set_cartridges_id, cartridge_id) I would like to not have code_set_cartridge table, but keep relationship : code_set -- 1:n -- cartridge In other words, how can I keep association between code_set and cartridge without intermediate table ? (using code_set_id as primary key in code_set and code_set_id as foreign key in cartridge). Mapping with GORM can be done without intermediate table?

However the location will always remain same as "D:/logFiles/" . Please help me in this as this is very urgent and important for me.

  • NSNotification on multiple objects

    - by Jan Hendrix
    Hi, In my NSApp delegate I add an observer of an object that is an NSWindow subclass that gets initiated in the delegate itself and that posts a notification once the window gets clicked. The selector is also in the delegate. From that same delegate class I initiate another object which when initiated adds itself as an observer for another window of the same NSWindow subclass of above and the selector is in this newly initiated class too. Both notifications get posted but the problem is that they get posted in both classes... Is this normal? I was hoping that it only got posted once.

  • Dynamic Objects for ASPxGridview

    - by André Snede Hansen
    I have a dictionary that is populated with data from a table, we are doing this so we can hold multiple SQL tables inside this object. This approached cannot be discussed. The Dictionary is mapped as a , and contains SQL column name and the value, and each dictionary resembles one row entry in the Table. Now I need to display this on a editable gridview, preferably the ASPxGridView. I already figured out that I should use Dynamic Objects(C#), and everything worked perfectly, up to the part where I find out that the ASPxGridview is built in .NET 2.0 and not 4.0 where Dynamic objects where implemented, therefor I cannot use it... As you cannot, to my knowledge, add rows to the gridview programmatically, I am out of ideas, and seek your help guys! protected void Page_Load(object sender, EventArgs e) { UserValidationTableDataProvider uvtDataprovider = _DALFactory.getProvider<UserValidationTableDataProvider>(typeof(UserValidationTableEntry)); string[] tableNames = uvtDataprovider.TableNames; UserValidationTableEntry[] entries = uvtDataprovider.getAllrecordsFromTable(tableNames[0]); userValidtionTableGridView.Columns.Clear(); Dictionary<string, string> firstEntry = entries[0].Values; foreach (KeyValuePair<string, string> kvp in firstEntry) { userValidtionTableGridView.Columns.Add(new GridViewDataColumn(kvp.Key)); } var dynamicObjectList = new List<dynamic>(); foreach (UserValidationTableEntry uvt in entries) { //dynamic dynObject = new MyDynamicObject(uvt.Values); dynamicObjectList.Add(new MyDynamicObject(uvt.Values)); } } public class MyDynamicObject : DynamicObject { Dictionary<string, string> properties = new Dictionary<string, string>(); public MyDynamicObject(Dictionary<string, string> dictio) { properties = dictio; } // If you try to get a value of a property // not defined in the class, this method is called. public override bool TryGetMember(GetMemberBinder binder, out object result) { // Converting the property name to lowercase // so that property names become case-insensitive. string name = binder.Name.ToLower(); string RResult; // If the property name is found in a dictionary, // set the result parameter to the property value and return true. // Otherwise, return false. bool wasSuccesfull = properties.TryGetValue(name, out RResult); result = RResult; return wasSuccesfull; } // If you try to set a value of a property that is // not defined in the class, this method is called. public override bool TrySetMember(SetMemberBinder binder, object value) { // Converting the property name to lowercase // so that property names become case-insensitive. properties[binder.Name.ToLower()] = value.ToString(); // You can always add a value to a dictionary, // so this method always returns true. return true; } } Now, I am almost certain that his "Dynamic object" approach, is not the one I can go with from here on. I hope you guys can help me :)!

  • Can't find method in the activity

It's just pseudo-code): class SecretModel(models.Model): some_unique_field = models.CharField(max_length=25, unique=True) # Notice this is unique. class MyModel(models.Model): secret_model = models.OneToOneField(SecretModel, editable=False) # Not in the form spam = models.CharField(max_length=15) foo = models.IntegerField() def clean(self): SecretModel.objects.create(some_unique_field=self.spam) Now if I go do this: MyModel.objects.create(spam='john', foo='OOPS') # Obviously foo won't take "OOPS" as it's an IntegerField. #.... ERROR HERE MyModel.objects.create(spam='john', foo=5) # So I try again here. #... IntegrityError because SecretModel with some_unique_field = 'john' already exists. I understand that I could put this into a view with a request transaction around it, but I want this to work in the Admin, and via an API, etc. Not just with forms, or views. How is it possible?
