  • Dojo extending dojo.dnd.Source, move not happening. Ideas?

    - by Soulhuntre
    Hey all, Ok... I have a simple dojo page with the bare essentials. Three UL's with some LI's in them. The idea si to allow drag-n-drop among them but if any UL goes empty due to the last item being dragged out, I will put up a message to the user to gie them some instructions. In order to do that, I wanted to extend the dojo.dnd.Source dijit and add some intelligence. It seemed easy enough. To keep things simple (I am loading Dojo from a CDN) I am simply declating my extension as opposed to doing full on module load. The declaration function is here... function declare_mockupSmartDndUl(){ dojo.require("dojo.dnd.Source"); dojo.provide("mockup.SmartDndUl"); dojo.declare("mockup.SmartDndUl", dojo.dnd.Source, { markupFactory: function(params, node){ //params._skipStartup = true; return new mockup.SmartDndUl(node, params); }, onDndDrop: function(source, nodes, copy){ console.debug('onDndDrop!'); if(this == source){ // reordering items console.debug('moving items from us'); // DO SOMETHING HERE }else{ // moving items to us console.debug('moving items to us'); // DO SOMETHING HERE } console.debug('this = ' + this ); console.debug('source = ' + source ); console.debug('nodes = ' + nodes); console.debug('copy = ' + copy); return dojo.dnd.Source.prototype.onDndDrop.call(this, source, nodes, copy); } }); } I have a init function to use this to decorate the lists... dojo.addOnLoad(function(){ declare_mockupSmartDndUl(); if(dojo.byId('list1')){ //new mockup.SmartDndUl(dojo.byId('list1')); new dojo.dnd.Source(dojo.byId('list1')); } if(dojo.byId('list2')){ new mockup.SmartDndUl(dojo.byId('list2')); //new dojo.dnd.Source(dojo.byId('list2')); } if(dojo.byId('list3')){ new mockup.SmartDndUl(dojo.byId('list3')); //new dojo.dnd.Source(dojo.byId('list3')); } }); It is fine as far as it goes, you will notice I left "list1" as a standard dojo dnd source for testing. The problem is this - list1 will happily accept items from lists 2 & 3 who will move or copy as apprriate. However lists 2 & 3 refuce to accept items from list1. It is as if the DND operation is being cancelled, but the debugger does show the dojo.dnd.Source.prototype.onDndDrop.call happening, and the paramaters do look ok to me. Now, the documentation here is really weak, so the example I took some of this from may be way out of date (I am using 1.4). Can anyone fill me in on what might be the issue with my extension dijit? Thanks!

  • Calling gawk from python

    - by chavanak
    Hi, I am trying to call gawk from python in this manner. import os import string import codecs ligand_file=open( "2WTKA_ab.txt", "r" ) #Open the receptor.txt file ligand_lines=ligand_file.readlines() # Read all the lines into the array ligand_lines=map( string.strip, ligand_lines ) ligand_file.close() for i in ligand_lines: os.system ( " gawk %s %s"%( "'{if ($2==""i"") print $0}'", 'unique_count_a_from_ac.txt' ) ) My problem is that "i" is not being replaced by the value it represent. The value "i" represents is an integer and not a string. Can anyone help me out? Cheers, Chavanak

  • How do I merge a transient entity with a session using Castle ActiveRecordMediator?

    - by Daniel T.
    I have a Store and a Product entity: public class Store { public Guid Id { get; set; } public int Version { get; set; } public ISet<Product> Products { get; set; } } public class Product { public Guid Id { get; set; } public int Version { get; set; } public Store ParentStore { get; set; } public string Name { get; set; } } In other words, I have a Store that can contain multiple Products in a bidirectional one-to-many relationship. I'm sending data back and forth between a web browser and a web service. The following steps emulates the communication between the two, using session-per-request. I first save a new instance of a Store: using (new SessionScope()) { // this is data from the browser var store = new Store { Id = Guid.Empty }; ActiveRecordMediator.SaveAndFlush(store); } Then I grab the store out of the DB, add a new product to it, and then save it: using (new SessionScope()) { // this is data from the browser var product = new Product { Id = Guid.Empty, Name = "Apples" }); var store = ActiveRecordLinq.AsQueryable<Store>().First(); store.Products.Add(product); ActiveRecordMediator.SaveAndFlush(store); } Up to this point, everything works well. Now I want to update the Product I just saved: using (new SessionScope()) { // data from browser var product = new Product { Id = Guid.Empty, Version = 1, Name = "Grapes" }; var store = ActiveRecordLinq.AsQueryable<Store>().First(); store.Products.Add(product); // throws exception on this call ActiveRecordMediator.SaveAndFlush(store); } When I try to update the product, I get the following exception: a different object with the same identifier value was already associated with the session: 00000000-0000-0000-0000-000000000000, of entity:Product" As I understand it, the problem is that when I get the Store out of the database, it also gets the Product that's associated with it. Both entities are persistent. Then I tried to save a transient Product (the one that has the updated info from the browser) that has the same ID as the one that's already associated with the session, and an exception is thrown. However, I don't know how to get around this problem. If I could get access to a NHibernate.ISession, I could call ISession.Merge() on it, but it doesn't look like ActiveRecordMediator has anything similar (SaveCopy threw the same exception). Does anyone know the solution? Any help would be greatly appreciated!

  • Best practice to handle Parent Form Child Form relation using Presentation Model

    - by Rajarshi
    According to Presentation Model notes by Martin Fowler and also on MSDN documentation about Presentation Model, it is explained that the Presentation Model Class should be unaware of the UI class and similarly Business Model Class should be unaware of the Presentation Model class. The UI should databind extensively to the Presentation Model, the Presentation Model in turn will co-ordinate with one or more Domain/Business Model objects to get the job done. The Presentation Model basically presents the Domain Model data in a way to facilitate maximum data binding in UI, allowing the UI take as less decisions as possible and thus increase testability of Presentation behaviours. This also makes the presentation model class generic, i.e. agnostic of any particular UI technology. Now, consider there is a List form (say CustomerList) and there is another Root form (say Customer) and there is a Use Case of allowing to Edit a Customer from the CustomerList form on a button click. For simplicity of discussion, consider that some actions took place when Customer List is opened from menu (i.e. Customer menu clicked) and the Customer List has been shown from the Menu click event. Now as per the above Use Case, I need to open the Customer Root UI (single Customer) from the Customer List. How do I do that? Build necessary objects (BusinessModel, PresentationModel, UI) in click event of Edit button and call CustomerEdit UI from there? Build the CustomerEdit UI from Presentation Model Class and show UI from presentation model? this can be done in any of the two ways below - a. Create objects in the following sequence DomainModel-PresentationModel-UIForm b. Use Unity.Resolve(); Either ways, Presentation Model is violated as the P model now has to the refer the concrete UI assembly, where CustomerEdit is located. Also the P Model has to refer and use a WinForm directly making it less UI technology agnostic. Even though the violations are in theory and can be ignored, I would still seek the community's opinion about whether I am going wrong direction. Please suggest if there's a better way to call the Child Form from the List (Parent) Form. Rajarshi

  • WMI failed to initialize the IWbemLocator using CoCreateInstance(CLSID_WbemLocator, 0, CLSCTX_INPROC

    - by Rahul
    Hi All, I am using WMI to get SMBIOS data and for that I am using following code to initialize the IWbemLocator interface through a call to CoCreateInstance. CoCreateInstance(CLSID_WbemLocator, 0, CLSCTX_INPROC_SERVER, IID_IWebLocator, (LPVOID *) &pLoc); But it always returns FAILURE. I think its due to some environment issue but wanted to know exact reason. Thanks in advance, Rahul

  • Using a Unicode format for Python's `time.strftime()`

    - by Hosam Aly
    I am trying to call Python's time.strftime() function using a Unicode format string: u'%d\u200f/%m\u200f/%Y %H:%M:%S' (\u200f is the "Right-To-Left Mark" (RLM).) However, I am getting an exception that the RLM character cannot be encoded into ascii: UnicodeEncodeError: 'ascii' codec can't encode character u'\u200f' in position 2: ordinal not in range(128) I have tried searching for an alternative but could not find a reasonable one. Is there an alternative to this function, or a way to make it work with Unicode characters?

  • Asynchronous sockets in C#

    - by IVlad
    I'm confused about the correct way of using asynchronous socket methods in C#. I will refer to these two articles to explain things and ask my questions: MSDN article on asynchronous client sockets and devarticles.com article on socket programming. My question is about the BeginReceive() method. The MSDN article uses these two functions to handle receiving data: private static void Receive(Socket client) { try { // Create the state object. StateObject state = new StateObject(); state.workSocket = client; // Begin receiving the data from the remote device. client.BeginReceive( state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state); } catch (Exception e) { Console.WriteLine(e.ToString()); } } private static void ReceiveCallback( IAsyncResult ar ) { try { // Retrieve the state object and the client socket // from the asynchronous state object. StateObject state = (StateObject) ar.AsyncState; Socket client = state.workSocket; // Read data from the remote device. int bytesRead = client.EndReceive(ar); if (bytesRead > 0) { // There might be more data, so store the data received so far. state.sb.Append(Encoding.ASCII.GetString(state.buffer,0,bytesRead)); // Get the rest of the data. client.BeginReceive(state.buffer,0,StateObject.BufferSize,0, new AsyncCallback(ReceiveCallback), state); } else { // All the data has arrived; put it in response. if (state.sb.Length > 1) { response = state.sb.ToString(); } // Signal that all bytes have been received. receiveDone.Set(); } } catch (Exception e) { Console.WriteLine(e.ToString()); } } While the devarticles.com tutorial passes null for the last parameter of the BeginReceive method, and goes on to explain that the last parameter is useful when we're dealing with multiple sockets. Now my questions are: What is the point of passing a state to the BeginReceive method if we're only working with a single socket? Is it to avoid using a class field? It seems like there's little point in doing it, but maybe I'm missing something. How can the state parameter help when dealing with multiple sockets? If I'm calling client.BeginReceive(...), won't all the data be read from the client socket? The devarticles.com tutorial makes it sound like in this call: m_asynResult = m_socClient.BeginReceive (theSocPkt.dataBuffer,0,theSocPkt.dataBuffer.Length, SocketFlags.None,pfnCallBack,theSocPkt); Data will be read from the theSocPkt.thisSocket socket, instead of from the m_socClient socket. In their example the two are one and the same, but what happens if that is not the case? I just don't really see where that last argument is useful or at least how it helps with multiple sockets. If I have multiple sockets, I still need to call BeginReceive on each of them, right?

  • ModalPopup CodeBehind Function Wait For User Response

    - by Snave
    I have set up a function which returns an enum of the button that the user clicked in the ModalPopup. I have a variable of type enum to store which button the user clicks in the button click event. In this function, I call the ModalPopupExtender's Show() method. My problem is, the function finishes out and returns the default enum (which is "none" since no button was clicked yet) before the ModalPopup can be shown and store which button the user clicks. So without changing the function to a method and using a different way to store the user's button click, how can I pause the function after the Show() method of the MPE has been called and wait for the user to click a button? Edit(11/20/2009): Clarification: On the aspx page, I include a ScriptManager, PlaceHolder, and an asp:Button with a codebehind click event. What I want is to click the button, then in the click event handler, I want to call a custom static class function that returns a variable. One of the arguments it takes is the PlaceHolder. The function creates all the necessary controls in the PlaceHolder needed to display a ModalPopup. It calls the created ModalPopupExtender's Show() method. What should happen: At this point is the ModalPopup gets displayed, the user clicks a button, that button's event handler fires, the button sets a variable indicating that it was clicked, it then calls the ModalPopupExtender's .Hide() method, and then the function returns the variable that indicates which button was clicked. We then return to the event handler from the original button that was clicked and the programmer can then perform some logic based on what variable was returned. Crux: When the ModalPopupExtender's .Show() method gets called, it does not display the ModalPopup until AFTER the function returns a default variable (because no button was clicked yet) and after the event handler from the original button that was clicked ends. What I need: After the ModalPopupExtender's .Show() method is called, I need the ModalPopup to get displayed immediately and I need the function to wait for a button click to be made from the ModalPopup. My thoughts: Some PostBack needs to be made to the page telling it to update and display the ModalPopup Panel. Then maybe a while loop can be run in the function that waits for a button to be clicked in the ModalPopup.
