  • How do I create custom Controls for my VS2005 toolbox?

    - by end-user
    Ok, this question might more about design theory. I have successfully created controls that show up in my toolbox, so I'm pretty sure I have the process right. Also, my "AutoToolboxPopulate" is set to true, so things are showing up as I create them. My question is this: I'm sub-classing a native Control for specialized use. When I derive my class from an exposed concrete class, such as BulletedList, my custom Control appears in my Toolbox. However, when I drop it back to the parent, such as ListControl, my Control is not listed (actually it's grayed out when I "List All"). What am I missing?

  • Flash automatically names objects on stage "instance#"

    - by meowMIX3R
    Hi, I have 2 TLF text boxes already placed on my main stage. In the property inspector window I give these the instance names: "txt1" and "txt2". I am trying to have a single mouseup event, and figure out which text box it occurred on. My document class has the following code: package { import flash.display.Sprite; import flash.events.KeyboardEvent; public class SingleEvent extends Sprite{ public function SingleEvent() { // constructor code root.addEventListener(KeyboardEvent.KEY_UP, textChanged,false,0,true); } private function textChanged(e:KeyboardEvent){ trace(e.target.name); trace(" " + e.target); switch(e.target){ case txt1: trace("txt1 is active"); break; case txt2: trace("txt2 is active"); break; default: break; } } } } Example output is: instance15 [object Sprite] instance21 [object Sprite] Since the objects are already on the stage, I am not sure how to get flash to recognize them as "txt1" and "txt2" instead of "instance#". I tried setting the .name property, but it had no effect. In the publish settings, I have "Automatically declare stage instances" checked. Also, is it possible to have a single change event for multiple slider components? The following never fires: root.addEventListener(SliderEvent.CHANGE, sliderChanged,false,0,true); Thanks for any tips

  • Delphi Unit local variables - how to make each instance unique?

    - by Justin
    Ok, this, I'm sure is something simple that is easy to do. The problem : I've inherited scary spaghetti code and am slowly trying to better it when new features need adding - generally when a refactor makes adding the new feature neater. I've got a bunch of code I'm packing into a single unit which, in different places in the application, controls the same physical thing in the outside world. The control appears in several places in the application and operates slightly differently in each instance. What I've done is to create a unit with all of the features I need which I can simply drop, as a frame, into each form that requires it. Each form then uses the unit's interface methods to customise the behaviour for each instance. The problem within the problem : In the unit in question (the frame) I have a variable declared in the IMPLEMENTATION section - local to the unit. I also have a procedure, declared in the TYPE section which takes an argument and assigns that argument to the local variable in question - each form passes a unique variable to each instance of the frame/unit. What I want it to do is for each instance of the frame to keep its own version of that variable, different from the others, and use that to define how it operates. What seems to be happening, however, is that all instances are using the same value, even if I explicitly pass each instance a different variable. ie: Unit FlexibleUnit; interface uses //the uses stuff type TFlexibleUnit=class(TFrame) //declarations including procedure makeThisInstanceX(passMeTheVar:integer); private // public // end; implementation uses //the uses var myLocalVar; procedure makeThisInstanceX(passMeTheVar:integer); begin myLocalVar:=passMeTheVar; end; //other procedures using myLocalVar //etc to the end; Now somewhere in another Form I've dropped this Frame onto the Design pane, sometimes two of these frames on one Form, and have it declared in the proper places, etc. Each is unique in that : ThisFlexibleUnit : TFlexibleUnit; ThatFlexibleUnit : TFlexibleUnit; and when I do a: ThisFlexibleUnit.makeThisInstanceX(var1); //want to behave in way "var1" ThatFlexibleUnit.makeThisInstanceX(var2); //want to behave in way "var2" it seems that they both share the same variable "myLocalVar". Am I doing this wrong, in principle? If this is the correct method then it's a matter of debugging what I have (which is too huge to post) but if this is not correct in principle then is there a way to do what I am suggesting? Thanks in advance, Stack Overflow - you guys (and gals!) are legendary.

  • Stack overflow error after creating a instance using 'new'

    - by Justin
    EDIT - The code looks strange here, so I suggest viewing the files directly in the link given. While working on my engine, I came across a issue that I'm unable to resolve. Hoping to fix this without any heavy modification, the code is below. void Block::DoCollision(GameObject* obj){ obj->DoCollision(this); } That is where the stack overflow occurs. This application works perfectly fine until I create two instances of the class using the new keyword. If I only had 1 instance of the class, it worked fine. Block* a = new Block(0, 0, 0, 5); AddGameObject(a); a = new Block(30, 0, 0, 5); AddGameObject(a); Those parameters are just x,y,z and size. The code is checked before hand. Only a object with a matching Collisonflag and collision type will trigger the DoCollision(); function. ((*list1)->m_collisionFlag & (*list2)->m_type) Maybe my check is messed up though. I attached the files concerned here http://celestialcoding.com/index.php?topic=1465.msg9913;topicseen#new. You can download them without having to sign up. The main suspects, I also pasted the code for below. From GameManager.cpp void GameManager::Update(float dt){ GameList::iterator list1; for(list1=m_gameObjectList.begin(); list1 != m_gameObjectList.end(); ++list1){ GameObject* temp = *list1; // Update logic and positions if((*list1)->m_active){ (*list1)->Update(dt); // Clip((*list1)->m_position); // Modify for bounce affect } else continue; // Check for collisions if((*list1)->m_collisionFlag != GameObject::TYPE_NONE){ GameList::iterator list2; for(list2=m_gameObjectList.begin(); list2 != m_gameObjectList.end(); ++list2){ if(!(*list2)->m_active) continue; if(list1 == list2) continue; if( (*list2)->m_active && ((*list1)->m_collisionFlag & (*list2)->m_type) && (*list1)->IsColliding(*list2)){ (*list1)->DoCollision((*list2)); } } } if(list1==m_gameObjectList.end()) break; } GameList::iterator end    = m_gameObjectList.end(); GameList::iterator newEnd = remove_if(m_gameObjectList.begin(),m_gameObjectList.end(),RemoveNotActive); if(newEnd != end)        m_gameObjectList.erase(newEnd,end); } void GameManager::LoadAllFiles(){ LoadSkin(m_gameTextureList, "Models/Skybox/Images/Top.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Models/Skybox/Images/Right.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Models/Skybox/Images/Back.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Models/Skybox/Images/Left.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Models/Skybox/Images/Front.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Models/Skybox/Images/Bottom.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Terrain/Textures/Terrain1.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Terrain/Textures/Terrain2.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Terrain/Details/TerrainDetails.bmp", GetNextFreeID()); LoadSkin(m_gameTextureList, "Terrain/Textures/Water1.bmp", GetNextFreeID()); Block* a = new Block(0, 0, 0, 5); AddGameObject(a); a = new Block(30, 0, 0, 5); AddGameObject(a); Player* d = new Player(0, 100,0); AddGameObject(d); } void Block::Draw(){ glPushMatrix(); glTranslatef(m_position.x(), m_position.y(), m_position.z()); glRotatef(m_facingAngle, 0, 1, 0); glScalef(m_size, m_size, m_size); glBegin(GL_LINES); glColor3f(255, 255, 255); glVertex3f(m_boundingRect.left, m_boundingRect.top, m_position.z()); glVertex3f(m_boundingRect.right, m_boundingRect.top, m_position.z()); glVertex3f(m_boundingRect.left, m_boundingRect.bottom, m_position.z()); glVertex3f(m_boundingRect.right, m_boundingRect.bottom, m_position.z()); glVertex3f(m_boundingRect.left, m_boundingRect.top, m_position.z()); glVertex3f(m_boundingRect.left, m_boundingRect.bottom, m_position.z()); glVertex3f(m_boundingRect.right, m_boundingRect.top, m_position.z()); glVertex3f(m_boundingRect.right, m_boundingRect.bottom, m_position.z()); glEnd(); // DrawBox(m_position.x(), m_position.y(), m_position.z(), m_size, m_size, m_size, 8); glPopMatrix(); } void Block::DoCollision(GameObject* obj){ GameObject* t = this;   // I modified this to see for sure that it was causing the mistake. // obj->DoCollision(NULL); // Just revert it back to /* void Block::DoCollision(GameObject* obj){     obj->DoCollision(this);   }   */ }

  • plugin instancing

    Hi guys, I am making a jquery tagging plugin. I have an issue that, When there is multiple instances of the plugin on the page, if you click on any <ul> that the plugin has been called on it will put focus on the <input /> in the last <ul> that the plugin has been called on.

  • Inheritance: possible to change base reference to something else?

    - by fred
    For example I have two classes, Base and Derived as shown below: class Base { public string Name { get; set; } public Base() { } } class Derived : Base { public Derived(Base b) { base = b; // doesn't compile, but is there any way to do something similar? } } So that they behave like this: Base b = new Base(); b.Name = "Bob"; Derived d = new Derived(b); d.Name = "John"; // b.Name is now "John" also Is this possible? I guess one way would be to keep the Base b reference in Derived and override Derived.Name to point to b.Name? Is there an easier way though, for example if I have like 50 properties to override? class Derived : Base { Base b; public override string Name { get { return b.Name; } set { b.Name = value; } } public Derived(Base b) { this.b = b; } }

  • Using JQuery to replace multiple instances of HTML on one page

    - by Kenneth B
    I've made a script which copies the alt attribute of an image and puts it into a <span>. It also formulates the information divided by a hyphen. It works like a charm, but only with one image. I would also like to wrap a <div> around the image to prevent unnecessary markup. Script snippets: HTML: <div id="hoejre"> <p> <span class="alignright"> <img src="tommy_stor.jpg" alt="Name - Title" width="162" height="219" /> <span></span> </span> </p> </div> jQuery: var alt = $("#hoejre p span img").attr("alt"); $('#hoejre p span span') .html("<strong>" + alt.replace("-", "</strong> <em>") + "</em>"); Output: <span class="alignright"> <img height="219" width="162" alt="Name - Title" src="tommy_stor.jpg"> <span> <strong>Name</strong><em>Title</em> </span> </span> How do you I repeat the effect on several images, with different information within?

  • Seekbar: two instances of OnSeekBarChangeListener issues

    - by fordays
    Hi, I'm using two SeekBar widgets and I am encountering some trouble having them coexist at the same time. Can anyone suggest how to modify my code to work on the same Activity?

  • In NHibernate, how do I combine two DetachedCriteria instances

    - by Trevor
    My scenario is this: I have a base NHibernate query to run of the form (I've coded it using DetachedCriteria , but describe it here using SQL syntax): SELECT * FROM Items I INNER JOIN SubItems S on S.FK = I.Key The user interface to show the results of this join allows the user to specify additional criteria: Say: I.SomeField = 'UserValue'. Now, I need the final load command to be: SELECT * FROM Items I INNER JOIN SubItems S on S.FK = I.Key WHERE I.SomeField = 'UserValue' My problem is: I've created a DetachedCriteria with the 'static' aspect of the query (the top join) and the UI creates a DetachedCriteria with the 'dynamic' component of the query. I need to combine the two into a final query that I can execute on the NHibernate session. DefaultCriteria.Add() takes an ICriterion (which are created using the Expression class, and maybe other classes I don't know of which could be the solution to my problem). Does anyone know how I might do what I want?

  • RequestDispatcher forward between Tomcat instances

    - by MontyBongo
    I have a scenario where I have single entry point Servlet and further Servlets that requests are forwarded to that undertake heavy processing. I am looking at options to distribute this load and I would like to know if it is possible using Tomcat or another platform to forward requests between Servlets sitting on different servers using a cluster type configuration or similar. I have found some documentation on clustering Servlets and Tomcat but none indicate if Servlet request forwarding is possible from what I can see. http://java.sun.com/blueprints/guidelines/designing_enterprise_applications_2e/web-tier/web-tier5.html http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html

  • Sending persisted JDO instances over GWT-RPC

    - by Ben Daniel
    I've just started learning Google Web Toolkit and finished writing the Stock Watcher tutorial app. Is my thinking correct that if one wants to persist a business object (like a Stock) using JDO and send it back and forth to/from the client over RPC then one has to create two separate classes for that object: One with the JDO annotations for persisting it on the server and another which is serialisable and used over RPC? I notice the Stock Watcher has separate classes and I can theorise why: Otherwise the gwt compiler would try to generate javascript for everything the persisted class referenced like JDO and com.google.blah.users.User, etc Also there may be logic on the server-side class which doesn't apply to the client and vice-versa. I just want to make sure I'm understanding this correctly. I don't want to have to create two versions of all my business object classes which I want to use over RPC if I don't have to.

  • jquery boxy plugin: prevent multiple instances of the same dialog when clicking the link multiple ti

    - by Lyon
    Hi, I'm using the Boxy jQuery plugin to open dialog windows and populating it through ajax. http://onehackoranother.com/projects/jquery/boxy/ Here's my code so far: $("a.create").click(function (e) { url = $(e.target).attr('href'); Boxy.load(url, {title:'Test'}); }); This opens up a dialog alright. However, if I click the link again, another dialog will open. How can I make it such that the previously opened Boxy dialog will come into focus? I only want one instance of this dialog. I tried assigning a variable to var ele = Boxy.load(); but the variable ele returns undefined... Alas, I can't make out much from the limited Boxy documentation available. Enabling the option modal: true would prevent the user from clicking on the link multiple times, but I don't want the overlay to show. Thanks for any light you can shed on this. -Lyon

  • Creating generic list of instances of a class.

    - by Jim Branson
    I have several projects where I build a dictionary from a small class. I'm using C# 2008, Visual studio 2008 and .net 3.5 This is the code: namespace ReportsTest { class Junk { public static Dictionary<string, string> getPlatKeys() { Dictionary<string, string> retPlatKeys = new Dictionary<string, string>(); SqlConnection conn = new SqlConnection("Data Source=JB55LTARL;Initial Catalog=HldiReports;Integrated Security=True"); SqlDataReader Dr = null; conn.Open(); SqlCommand cmnd = new SqlCommand("SELECT Make, Series, RedesignYear, SeriesName FROM CompPlatformKeys", conn); Dr = cmnd.ExecuteReader(); while (Dr.Read()) { utypPlatKeys rec = new utypPlatKeys(Dr); retPlatKeys.Add(rec.Make + rec.Series + rec.RedesignYear, rec.SeriesName); } conn = null; Dr = null; return retPlatKeys; } } public class utypPlatKeys { public string Make { get; set; } public string Series { get; set; } public string RedesignYear { get; set; } public string SeriesName { get; set; } public utypPlatKeys(SqlDataReader dr) { this.Make = dr.GetInt16(dr.GetOrdinal("Make")).ToString("D3"); this.Series = dr.GetInt16(dr.GetOrdinal("Series")).ToString("D3"); this.RedesignYear = dr.GetInt16(dr.GetOrdinal("RedesignYear")).ToString(); this.SeriesName = dr["SeriesName"].ToString(); } } } The immediate window shows all of the entries in retPlatKeys and if you hover over retPlatKeys after loading it indicates the number of elements like this: "retPlatKeys| Count = 923 which is correct. I went to create a new project using this pattern only now the immediate window says retPlatKeys is out of scope and hovering over retPlatKeys after loading I get something like retPlatKeys|0x0000000002578900. Any help is greatly appreciated.

  • Extended Django base-class with multiple instances

When (in the Admin) I create an instance of Actor, and this person is also a Director, it won't save because of the unique = True. Any ideas how to solve this problem? (generic foreign keys?) Thx

  • Django: Using 2 different AdminSite instances with different models registered

    - by omat
    Apart from the usual admin, I want to create a limited admin for non-staff users. This admin site will have different registered ModelAdmins. I created a folder /useradmin/ in my project directory and similar to contrib/admin/_init_.py I added an autodiscover() which will register models defined in useradmin.py modules instead of admin.py: # useradmin/__init__.py def autodiscover(): # Same as admin.autodiscover() but registers useradmin.py modules ... for app in settings.INSTALLED_APPS: mod = import_module(app) try: before_import_registry = copy.copy(site._registry) import_module('%s.useradmin' % app) except: site._registry = before_import_registry if module_has_submodule(mod, 'useradmin'): raise I also cretated sites.py under useradmin/ to override AdminSite similar to contrib/admin/sites: # useradmin/sites.py class UserAdminSite(AdminSite): def has_permission(self, request): # Don't care if the user is staff return request.user.is_active def login(self, request): # Do the login stuff but don't care if the user is staff if request.user.is_authenticated(): ... else: ... site = UserAdminSite(name='useradmin') In the project's URLs: # urls.py from django.contrib import admin import useradmin admin.autodiscover() useradmin.autodiscover() urlpatterns = patterns('', (r'^admin/', include(admin.site.urls)), (r'^useradmin/', include(useradmin.site.urls)), ) And I try to register different models in admin.py and useradmin.py modules under app directories: # products/useradmin.py import useradmin class ProductAdmin(useradmin.ModelAdmin): pass useradmin.site.register(Product, ProductAdmin) But when registering models in useradmin.py like useradmin.site.register(Product, ProductAdmin), I get 'module' object has no attribute 'ModelAdmin' exception. Though when I try this via shell; import useradmin from useradmin import ModelAdmin does not raise any exception. Any ideas what might be wrong? Edit: I tried going the @Luke way and arranged the code as follows as minimal as possible: (file paths are relative to the project root) # admin.py from django.contrib.admin import autodiscover from django.contrib.admin.sites import AdminSite user_site = AdminSite(name='useradmin') # urls.py (does not even have url patterns; just calls autodiscover()) import admin admin.autodiscover() # products/admin.py import admin from products.models import Product admin.user_site.register(Product) As a result I get an AttributeError: 'module' object has no attribute 'user_site' when admin.user_site.register(Product) in products/admin.py is called. Any ideas? Solution: I don't know if there are better ways but, renaming the admin.py in the project root to useradmin.py and updating the imports accordingly resolved the last case, which was a naming and import conflict.

  • Nested instances in C#

    - by user32848
    I'm trying to translate some C++ code for a neural net into C#. I first took the C++ code, from a 1993 book, and ran it. Then translated it using the STL and it ran again. Now I'm trying to get it into C# with Visual Web Developer 2008 Express. The original code used "friend" classes and I'm just trying to do the same making everything "public". The following code compiles but only gives null references when run: public class ineuron { public Double weight, activation; public ineuron(Double set_wt) { weight = set_wt; } ... public class netwrk { public oneuron onrn; public ineuron in1, in2, in3, in4; public netwrk( Double inp_1, Double inp_2, Double inp_3, Double inp_4 ) { ineuron in1 = new ineuron(inp_1); ineuron in2 = new ineuron(inp_2); ... and later, in some code called by a button push: netwrk ntw = new netwrk(i_n1, i_n2, i_n3, i_n4); Unfortunately, trying to use: ntw.in1.activation etc. leads to null reference runtime errors. What am I forgetting to do? Barney

  • Deploy multiple instances of an EAR (representing versions) to Glassfish

    - by Thorbjørn Ravn Andersen
    I basically want to be able to deploy multiple versions of the same EAR file to the same server (Glassfish instance?) , and have a unique path to each version separating them. From my reading on this it appears that multiple EARs deploy to the root of the web server namespace so that they can coexist if they do not have colliding context-root's of WAR's. In my case I'd rather have that instead of everything going under "/", I'd like to be able to brand a given EAR-file build to ALWAYS deploy under a given path like "/foo-20100319" or "/foo-CUSTOMER-20010101". This can easily be done with a single WAR file just by renaming it. I do not need or want them to disturb each other. It is my understanding that this remapping is outside the scope of the application.xml file, so I found that http://docs.sun.com/app/docs/doc/820-7693/beayr?a=view says that I can specify web-uri and context-root, but I am not certain that what I wish to do, can be specified with these in Glassfish. How should I approach this? I have full control over the build process.

  • StructureMap Autowiring with two different instances of the same interface

    - by Lambda
    For the last two days, i tried my best to learn something about StructureMap, using an old project of mine as an concrete implementation example. I tried to simplify my question as much as possible. While i will post my examples in vb.net, answers with examples in C# are also okay. The project includes an interfaces called IDatabase which connects itself to a Database. The important part looks like this. Public Interface IDatabase Function Connect(ByVal ConnectionSettings As ConnectionSettings) As Boolean ReadOnly Property ConnectionOpen As Boolean [... more functions...] End Interface Public Class MSSQLConnection Implements IDatabase Public Function Connect(ByVal ConnectionSettings As ConnectionSettings) As Boolean Implements IDatabase.Connect [... Implementation ...] End Function [... more implementations...] End Class ConnectionSettings is a structure that has all the information needed to connect to a Database. I want to open the Database Connection once and use it for every single connection in the project, so i register a instance in the ObjectFactory. dim foo = ObjectFactory.GetInstance(Of MSSQLConnection)() dim bar as ConnectionSettings foo.connect(bar) ObjectFactory.Configure(Sub(x) x.For(Of IDatabase).Use(foo)) Up until this part, everything works like a charm. Now, i get to a point where i hav e classes that need an additional instance of IDatabase because they connect to a second database. Public Class ExampleClass Public Sub New(ByVal SameOldDatabase as IDatabase, ByVal NewDatabase as IDatabase) [...] Magic happens here [...] End Sub End Class I want this second IDatabase to behave much like the first one. I want it to use a concrete, single instance and want to connect it to a different database invoking Connect with a different ConnectionSettings. The problem is: While i'm pretty sure it's somewhow possible, (my initial idea was registering ExampleClass with alternative constructor arguments), i actually want to do it without registering ExampleClass. This probably involves more configuration, but i have no idea how to do it. So, basically, it comes down to this question: How do i configurate the ObjectFactory in a way that the autowiring always invokes the constructor with object Database1 for the first IDatabase parameter and object Database2 for the second one (if there is one?)

  • IoC - Dynamic Composition of object instances

    - by Joshua Starner
    Is there a way using IoC, MEF [Imports], or another DI solution to compose dependencies on the fly at object creation time instead of during composition time? Here's my current thought. If you have an instance of an object that raises events, but you are not creating the object once and saving it in memory, you have to register the event handlers every time the object is created. As far as I can tell, most IoC containers require you to register all of the classes used in composition and call Compose() to make it hook up all the dependencies. I think this may be horrible design (I'm dealing with a legacy system here) to do this due to the overhead of object creation, dependency injection, etc... but I was wondering if it was possible using one of the emergent IoC technologies. Maybe I have some terminology mixed up, but my goal is to avoid writing a framework to "hook up all the events" on an instance of an object, and use something like MEF to [Export] handlers (dependencies) that adhere to a very specific interface and [ImportMany] them into an object instance so my exports get called if the assemblies are there when the application starts. So maybe all of the objects could still be composed when the application starts, but I want the system to find and call all of them as the object is created and destroyed.

  • How to use multiple instances of a usercontrol (with jquery) on the same page

    - by Julian
    Hi All, I've been working on an usercontrol with a jquery timer in it. At first I had the jquery within the usercontrol. But when I add 2 of those controls to my page the second usercontrol isn't showing it's data very well. Now I've put the jquery into the mainpage and the usercontrol only uses the id's of the jquery. Here is my usercontrol: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %> <style type="text/css"> #mainpanel { width: 145px; height: 123px; } </style> <div id="mainpanel"> <div> test</div> <div id="shortly" style="background-color: #FFFFFF"> </div> <button id="resetButton"> Reset </button> </div> Mainpage: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Register Src="WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>hoi</title> <script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script> <link href="Css/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script> <script type="text/javascript" src="Scripts/jquery.countdown.js"></script> <script type="text/javascript"> $(document).ready(function () { $(function() { $("#mainpanel"); }); shortly = new Date(); shortly.setSeconds(shortly.getSeconds() + 5.5); $('#shortly').countdown({ until: shortly, onExpiry: liftOff, layout: '{sn}', }); $('#resetButton').click(function () { $('#mainpanel').effect("highlight", {}, 700 ); $('#shortly').effect("highlight", {}, 700 ); shortly = new Date(); shortly.setSeconds(shortly.getSeconds() + 5.5); $('#shortly').countdown('change', { until: shortly }); }); function liftOff() { // refresh the page window.location = window.location; } }); </script> </head> <body> <uc1:WebUserControl ID="WebUserControl1" runat="server" /> </body> </html> But still my usercontrols are acting weird, now my question is: "How can I make the SAME usercontrols work properly on ONE page?" Both of those use the same jquery code but the buttons etc. should only work within the usercontrol itself.

  • Code Golf: Quickly Build List of Keywords from Text, Including # of Instances

    - by Jonathan Sampson
    I've already worked out this solution for myself with PHP, but I'm curious how it could be done differently - better even. The two languages I'm primarily interested in are PHP and Javascript, but I'd be interested in seeing how quickly this could be done in any other major language today as well (mostly C#, Java, etc). Return only words with an occurrence greater than X Return only words with a length greater than Y Ignore common terms like "and, is, the, etc" Feel free to strip punctuation prior to processing (ie. "John's" becomes "John") Return results in a collection/array Extra Credit Keep Quoted Statements together, (ie. "They were 'too good to be true' apparently")Where 'too good to be true' would be the actual statement Extra-Extra Credit Can your script determine words that should be kept together based upon their frequency of being found together? This being done without knowing the words beforehand. Example: "The fruit fly is a great thing when it comes to medical research. Much study has been done on the fruit fly in the past, and has lead to many breakthroughs. In the future, the fruit fly will continue to be studied, but our methods may change." Clearly the word here is "fruit fly," which is easy for us to find. Can your search'n'scrape script determine this too? Source text: http://sampsonresume.com/labs/c.txt Answer Format It would be great to see the results of your code, output, in addition to how long the operation lasted.
