• Optimization in Common Decalaration

  - by Pratik

  Its a 3-tier ASP.NET Website Project In Data Layer there is class "Common Decalaration" in which lot of common things are mentioned. Something this way : public class CommonDeclartion { #region Common Messages public const string RECORD_INSERT_MSG = "Record Inserted Successfully "; public const string RECORD_UPDATE_MSG = "Record Updated Successfully"; public const string RECORD_DELETE_MSG = "Record Deleted Successfully"; public const string ERROR_MSG = "Error Ocuured while Perfoming This Action."; public const string UserID_Incorrect = "Please Enter The Correct User ID."; public const string RECORD_ALREADY_EXIT = "Record Already Exit"; public const string NO_RECORD = "No Record found."; #endregion } Can this be more optimized in terms of : 1.Perfomance 2.Security(if any) 3.Code Readablity or Reusablity I thought of using enum but can't figure that out : enum CommonMessages { RECORD_INSERT_MSG "Record Inserted Successfully.", RECORD_UPDATE_MSG "Record Updated Successfully.", RECORD_DELETE_MSG "Record Deleted Successfully.", ERROR_MSG "Error Ocuured while Perfoming This Action.", UserID_Incorrect "Please Enter The Correct User ID.", RECORD_ALREADY_EXIT "Record Already Exit.", NO_RECORD "No Record found.", } or else should keep them in some collections like dictionary/NameValueCollection or so or i have to keep them in XML in form of key/value pair and reterive from it ? What can be better way keeping in mind 1.Perfomance 2.Security(if any) 3.Code Readablity or Reusablity

• Problem with ModelAndView and ModelMap in AnnotationController, Springframework

  - by saltfactory

  I have a question that is a point difference between ModelAndView and ModelMap. I want to maintain modelAndView when requestMethod is "GET" and requestMethod is "POST". My modelAndView saved others. So I made modelAndView return type to "GET", "POST" methods. But, Request lost commandObject, form:errors..., if request return showForm on "POST" because request validation failed. example) private ModelAndView modelAndView; public ControllerTest{ this.modelAndView = new ModelAndView(); } @RequestMapping(method = RequestMethod.GET) public ModelAndView showForm(ModelMap model) { EntityObject entityObject = new EntityObject(); CommandObject commandObject = new CommandObject(); commandObject.setEntityObject(entityObject); model.addAttribute("commandObject", commandObject); this.modelAndView.addObject("id", "GET"); this.modelAndView.setViewName("registerForm"); return this.modelAndView; } @RequestMapping(method = RequestMethod.POST) public ModelAndView submit(@ModelAttribute("commandObject") CommandObject commandObject, BindingResult result, SessionStatus status) { this.commandValidator.validate(commandObject, result); if (result.hasErrors()) { this.modelAndView.addObject("id", "POST"); this.modelAndView.setViewName("registerForm"); return this.modelAndView; } else { this.modelAndView.addObject("id", "after POST"); this.modelAndView.setViewName("success"); } status.setComplete(); return this.modelAndView; }

• can bind successfully to the ldap server, but needs to know how to find user w/i AD

  - by Brad

  I create a login form to bind to the ldap server, if successful, it creates a session (which the user's username is stored within), then I go to another page that has session_start(); and it works fine. What I want to do now, is add code to test if that user is a member of a specific group. So in theory, this is what I want to do if(username session is valid) { search ldap for user -> get list of groups user is member of foreach(group they are member of) { switch(group) { case STAFF: print 'they are member of staff group'; $access = true; break; default: print 'not a member of STAFF group'; $access = false; break; } if(group == STAFF) { break; } } if($access == TRUE) { // you have access to the content on this page } else { // you do not have access to this page } } How do I do a ldap_search w/o binding? I don't want to keep asking for their password on each page, and I can't pass their password thru a session. Any help is appreciated.

• Syncing Data to Remote Services, Best Practices for Caching?

  - by viatropos

  I want to be able to publish events to Eventbrite, Eventful, and Google Calendar for my Google Apps. Each service has slightly different properties for events... I will be syncing many other things too, such as users with Google Contacts and MailChimp, Documents with Google Docs and some other services, etc... So I'm wondering, what is the recommended way of retrieving the data for the end user so that it's reasonably maintainable and optimized? Here are the things I'm thinking that I'm having trouble with: My App keeps a central database of all the models (Event, Document, User, Form, etc.), and whenever Admin creates an object (e.g. create through Eventbrite or through our Admin panel), we sync them and store a copy in our local database. When User goes to the site /events, App retrieves the events from the database. Read Events from a target feed, such as the Eventbrite or Eventful feed, and scrap the local database. Basically, I'm wondering, if we're storing all of the data on a remote service, do we really need to have a local database copy of the data? When would we need to have a local database, when wouldn't we?

• Use a foreign key mapping to get data from the other table using Python and SQLAlchemy.

  - by Az

  Hmm, the title was harder to formulate than I thought. Basically, I've got these simple classes mapped to tables, using SQLAlchemy. I know they're missing a few items but those aren't essential for highlighting the problem. class Customer(object): def __init__(self, uid, name, email): self.uid = uid self.name = name self.email = email def __repr__(self): return str(self) def __str__(self): return "Cust: %s, Name: %s (Email: %s)" %(self.uid, self.name, self.email) The above is basically a simple customer with an id, name and an email address. class Order(object): def __init__(self, item_id, item_name, customer): self.item_id = item_id self.item_name = item_name self.customer = None def __repr__(self): return str(self) def __str__(self): return "Item ID %s: %s, has been ordered by customer no. %s" %(self.item_id, self.item_name, self.customer) This is the Orders class that just holds the order information: an id, a name and a reference to a customer. It's initialised to None to indicate that this item doesn't have a customer yet. The code's job will assign the item a customer. The following code maps these classes to respective database tables. # SQLAlchemy database transmutation engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() customers_table = Table('customers', metadata, Column('uid', Integer, primary_key=True), Column('name', String), Column('email', String) ) orders_table = Table('orders', metadata, Column('item_id', Integer, primary_key=True), Column('item_name', String), Column('customer', Integer, ForeignKey('customers.uid')) ) metadata.create_all(engine) mapper(Customer, customers_table) mapper(Orders, orders_table) Now if I do something like: for order in session.query(Order): print order I can get a list of orders in this form: Item ID 1001: MX4000 Laser Mouse, has been ordered by customer no. 12 What I want to do is find out customer 12's name and email address (which is why I used the ForeignKey into the Customer table). How would I go about it?

• Client validate in MVC 2

  - by khoailang

  Hello, I'm very new in MVC 2, Let say, I have a page with 1 text box and 2 input typed submit, "back" and "next". I'm using client validation like this: "" type="text/javascript"/" " type="text/javascript"/ " type="text/javascript"/ . . . <% Html.EnableClientValidation(); % . . . . . . and validation rule used for that text box is [StringLength(100, ErrorMessage="This field should be no longer than 100")] My wish is that validation rules will be applied only when I click on Next button. And when I click on Back button, no validation error message will be displayed and form will be posted to server. Is it possible to do that? could you please tell me how? My problem now is that when I click Back, validation rules are applied and prevent me from posting back to server.

• Valid javascript object property names

  - by hawkettc

  I'm trying to work out what is considered valid for the property name of a javascript object. For example var b = {} b['-^colour'] = "blue"; // Works fine in Firefox, Chrome, Safari b['colour'] = "green"; // Ditto alert(b['-^colour']); // Ditto alert(b.colour); // Ditto for(prop in b) alert(prop); // Ditto //alert(b.-^colour); // Fails (expected) This post details valid javascript variable names, and '-^colour' is clearly not valid (as a variable name). Does the same apply to object property names? Looking at the above I'm trying to work out if b['-^colour'] is invalid, but works in all browsers by quirk, and I shouldn't trust it to work going forward b['-^colour'] is completely valid, but it's just of a form that can only be accessed in this manner - (it's supported so Objects can be used as maps perhaps?) Something else As an aside, a global variable in javascript might be declared at the top level as var abc = 0; but could also be created (as I understand it) with window['abc'] = 0; the following works in all the above browsers window['@£$%'] = "bling!"; alert(window['@£$%']); Is this valid? It seems to contradict the variable naming rules - or am I not declaring a variable there? What's the difference between a variable and an object property name? Cheers, Colin

• JSON image viewer not working in firefox

  - by jarga

  I have tried to find out why JSON is not working in Firefox all over this forum and the internet. It works on tablets, ie, safari. It works on my desktop in firefox. It only does not work after uploading I've tried a few things (commented out), such as mimeType with no solution. I have tried using the $.ajax with no better luck. Firefox had no javascript errors. I'm using jQuery 1.7. Console.log is printing out the data. $(document).ready(function(){ jQuery.support.cors = true; //$.ajaxSetup({ mimeType: "application/json" }); /*$.ajaxSetup({ scriptCharset: "utf-8" , contentType: "application/json; charset=utf-8"}); */ // loading pictures $.getJSON("intro.json?format=json", function(data){ var links = ''; var imageload = ''; var title = ''; console.log(data) $.each(data, function(key, item){ links += ' <a href=' + item.image + '>' + key + '</a>'; imageload += '<img src="' + item.image + ' " />'; title += item.alt; }); $('.introCon').html(imageload); $('.introCon img').hide(); $('.introCon img:last').fadeIn(500); $('.introCon img').fadeIn(1000); rotatePics(2); }); }); function rotatePics(currentPhoto) { var numberOfPhotos = $('.introCon img').length; currentPhoto = currentPhoto % numberOfPhotos; $('.introCon img').eq(currentPhoto).fadeOut( function() { // re-order the z-index $('.introCon img').each(function(i) { $(this).css( 'zIndex', ((numberOfPhotos - i) + currentPhoto) % numberOfPhotos ); }); $(this).show(); setTimeout(function() {rotatePics(++currentPhoto);}, 3000); }); } Here is the simple JSON from a separate file. { "1" : { "image" : "portfolio/chrpic.png", "alt" : "Blah.", "detail": "Quartz"}, "2" : { "image" : "portfolio/mysspic.png", "alt" : "Landing page.", "detail": "Container"}, "3" : { "image" : "portfolio/decode-pic3.png", "alt" : "Decode this.", "detail": "Landing page 2"}, "4" : { "image" : "portfolio/simple-think-pic.png", "alt" : "Simple Think", "detail": "simpilify your life"} }

• C++ BigInt multiplication conceptual problem

  - by Kapo

  I'm building a small BigInt library in C++ for use in my programming language. The structure is like the following: short digits[ 1000 ]; int len; I have a function that converts a string into a bigint by splitting it up into single chars and putting them into digits. The numbers in digits are all reversed, so the number 123 would look like the following: digits[0]=3 digits[1]=3 digits[2]=1 I have already managed to code the adding function, which works perfectly. It works somewhat like this: overflow = 0 for i ++ until length of both numbers exceeded: add numberA[ i ] to numberB[ i ] add overflow to the result set overflow to 0 if the result is bigger than 10: substract 10 from the result overflow = 1 put the result into numberReturn[ i ] (Overflow is in this case what happens when I add 1 to 9: Substract 10 from 10, add 1 to overflow, overflow gets added to the next digit) So think of how two numbers are stored, like those: 0 | 1 | 2 --------- A 2 - - B 0 0 1 The above represents the digits of the bigints 2 (A) and 100 (B). - means uninitialized digits, they aren't accessed. So adding the above number works fine: start at 0, add 2 + 0, go to 1, add 0, go to 2, add 1 But: When I want to do multiplication with the above structure, my program ends up doing the following: Start at 0, multiply 2 with 0 (eek), go to 1, ... So it is obvious that, for multiplication, I have to get an order like this: 0 | 1 | 2 --------- A - - 2 B 0 0 1 Then, everything would be clear: Start at 0, multiply 0 with 0, go to 1, multiply 0 with 0, go to 2, multiply 1 with 2 How can I manage to get digits into the correct form for multiplication? I don't want to do any array moving/flipping - I need performance!

• How to Prevent PostBack Event Handler from Firing

  - by user331744

  I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs. I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator. Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing. Any idiea on how I can accomplish this? Please let me know if you need further details

• Disabling browser print options (headers, footers, margins) from page?

  - by Anthony

  I have seen this question asked in a couple of different ways on SO and several other websites, but most of them are either too specific or out-of-date. I'm hoping someone can provide a definitive answer here without pandering to speculation. Is there a way, either with CSS or javascript, to change the default printer settings when someone prints within their browser? And of course by "prints from their browser" I mean some form of HTML, not PDF or some other plug-in reliant mime-type. Please note: If some browsers offer this and others don't (or if you only know how to do it for some browsers) I welcome browser-specific solutions. Similarly, if you know of a mainstream browser that has specific restrictions against EVER doing this, that is also helpful, but some fairly up-to-date documentation would be appreciated. (simply saying "that goes against XYZ's security policy" isn't very convincing when XYZ has made significant changes in said policy in the last three years). Finally, when I say "change default print settings" I don't mean forever, just for my page, and I am referring specifically to print margins, headers, and footers. I am very aware that CSS offers the option of changing the page orientation as well as the page margins. One of the many struggles is with Firefox. If I set the page margins to 1 inch, it ADDS this to the half inch it already puts into place. I very much want to reduce the usage of PDFs on my client's site, but the infringement on presentation (as well as the lack of reliability) are their main concern.

• Get information from WebPage.

  - by william-hu

  I want to set up an app which can get the information from a particular web page. Then i display the value which got from that page to the iPhone user. Detail:In the webpage on server ,there is the schedule for bus time. If the user input origin and terminus then show the user the time information(list on webpage) in a label. That's all. What i have finished is : Open the iphone app, input two value(origin and terminus) to UITextField. Send the URL to server. Get the page, and show in UIWebView. What my problem next is how should i get the information form that page into another two labels to give the user about the bus time. I have store data in my Array receiveData: self.receivedData = data; I am not clear the data i received is XML or what? And how should i pick-up the value i want. (should i save the value to property list and the read the value?) Thank you so much!

• C#: Populating a UI using separate threads.

  - by Andrew

  I'm trying to make some sense out of an application Ive been handed in order to track down the source of an error. Theres a bit of code (simplified here) which creates four threads which in turn populate list views on the main form. Each method gets data from the database and retrieves graphics from a resource dll in order to directly populate an imagelist and listview. From what Ive read on here (link) updating UI elements from any thread other than the UI thread should not be done, and yet this appears to work? Thread t0 = new Thread(new ThreadStart(PopulateListView1)); t0.IsBackground = true; t0.Start(); Thread t1 = new Thread(new ThreadStart(PopulateListView2)); t1.Start(); Thread t2 = new Thread(new ThreadStart(PopulateListView3)); t2.Start(); Thread t3 = new Thread(new ThreadStart(PopulateListView4)); t3.Start(); The error itself is a System.InvalidOperationException "Image cannot be added to the ImageList." which has me wondering if the above code is linked in some way. Iis this method of populating the UI recommended and if not what are the possible complications resulting from it?

• Programmatically change the icon of the executable

  - by Dennis Delimarsky

  I am developing an application called WeatherBar. Its main functionality is based on its interaction with the Windows 7 taskbar — it changes the icon depending on the weather conditions in a specific location. The icons I am using in the application are all stored in a compiled native resource file (.res) — I am using it instead of the embedded resource manifest for icons only. By default, I modify the Icon property of the main form to change the icons accordingly and it works fine, as long as the icon is not pinned to the taskbar. When it gets pinned, the icon in the taskbar automatically switches to the default one for the executable (with index 0 in the resource file). After doing a little bit of research, I figured that a way to change the icon would be changing the shortcut icon (as all pinned applications are actually shortcuts stored in the user folder). But it didn't work. I assume that I need to change the icon for the executable, and therefore use UpdateResource, but I am not entirely sure about this. My executable is not digitally signed, so it shouldn't be an issue modifying it. What would be the way to solve this issue?

• Click behaviour - Difference in IE and FF ?!

  - by OlliD

  Hey folks, i just came to the conclusion that a project i am currently working on might have a "logical" error in functionality. Currently I'am using server technology with PHP/MySQL and JQuery. Within the page there's a normal link reference with tag <a href="contentpage?page=xxx">next step</a> The pain point now seems to be the given jquery click event on the same element. The intension was to save the (current) content of the page (- form elements) via another php script using the php session command. For any reason, IE can handle the click event of Jquery right before executing the standard html command, that reloads the current page again with the new page parameter. By using FF the behaviour is different. I assume, that FF first execute the html command and afterwards execute the javascript code which handles the click event. Therefore the resultset here is wrong respectivly empty. My question now is whether you made the same experience and how you handled / wordarrounded this problem. I'd be thankful fur any of your tips or further feedback. Maybe you also have a solution on how to rethink about the current architecture. Regards, Oliver

• How to Store and Retrieve Images Using SQL Server (Server Management Studio)

  - by Joe Majewski

  I am having difficulties when trying to insert files into a SQL Server database. I'll try to break this down as best as I can: What data type should I be using to store image files (jpeg/png/gif/etc)? Right now my table is using the image data type, but I am curious if varbinary would be a better option. How would I go about inserting the image into the database? Does Microsoft SQL Server Management Studio have any built in functions that allow insertions of files into tables? If so, how is that done? Also, how could this be done through the use of an HTML form with PHP handling the input data and placing it into the table? How would I fetch the image from the table and display it on the page? I understand how to SELECT the cell's contents, but how would I go about translating that into a picture. Would I have to have a header(Content type: image/jpeg)? I have no problem doing any of these things with MySQL, but the SQL Server environment is still new to me, and I am working on a project for my job that requires the use of stored procedures to grab various data. Any and all help is appreciated.

• HELP Retrieving the url parameter from a JSON store from a EXTJS ComboBox

  - by Newbie

  I am having a problem retrieving the parameters from the url section of a json store for a combobox in EXTJS from my code behind page in c#. The following is the code in the store: var ColorStore = new Ext.data.JsonStore( { autoLoad: true, url: '/proxies/ReturnJSON.aspx?view=rm_colour_view', root: 'Rows', fields: ['company', 'raw_mat_col_code', 'raw_mat_col_desc'] }); And the following code is in my code behind page: protected void Page_Load(object sender, EventArgs e) { string jSonString = ""; connectionClass.connClass func = new connectionClass.connClass(); DataTable dt = func.getDataTable("sELECT * from rm_colour_view"); //Response.Write(Request.QueryString["view"]); string w = Request.Params.Get("url"); string z = Request.Params.Get("view"); string x = Request.Params.Get("view="); string c = Request.Params.Get("?view"); string s = Request.QueryString.Get("view"); string d = Request.Params["?view="]; string f = Request.Form["ColorStore"]; jSonString = Serialize(dt); Response.Write(jSonString); } The string w has gives the following output: /proxies/ReturnJSON.aspx but all the others strings return null... How can rm_colour_view from the datastore then be retrived??? Any help would be appreciated! Thanks

• Concrete examples of state sharing between multiple viewmodels (WPF MVVM)

  - by JohnMetta

  I have a WPF/Entity Framework (4.0) project with many objects. I'd like to build the application so that that I can have object selection state shared across viewmodels. For Example: We have Cars, Drivers, Passengers, and Cargo classes. We also have UserControls for CarList, DriverList, etc. and editor windows for CarEditor, DriverEditor, etc. Furthermore, we have viewmodels for all of these (CarListViewModel, DriverListViewModel, CargoEditorViewModel, etc). This all composes a dockable interface where the user can have multiple object lists, editors, and viewers open. What I want is a concrete code example of how to wireup multiple viewmodels so that selecting a car in the CarList will cause that car to go live in the CarEditorView, but also be selected in any other view for which the context is valid (such as a DriverByCarView- or just DriverList if there is a filter predicate). There are a number of suggestions and discussions based on this question. The two methods that seem to dominate are: 3018307: Discusses state sharing by mentioning a messaging subsystem 1159035: Discusses state sharing by using an enclosing viewmodel Is one of these approaches better than the other? Does anyone have a concrete example of either/both of these methods in the form of a write-up or small code project? I'm still learning WPF, so pointers to entry points for reading API fundamentals are appreciated, but looking at code examples is where I usually go. Thanks In case anyone is interested, here are some other similar discussions: 3816961: Discusses returning multiple viewmodels depending on object type (i.e. a collection of arbitrary types adhering to a specific interface) 1928130: Discusses whether it is a good idea to aggregate viewmodels as properties of other viewmodels (e.g. a MainWindow viewmodel composed of panel viewmodels) 1120061: Essentially discusses whether to have use a viewmodel-per-model strategy or a viewmodel-per-view-element strategy. 4244222: Discusses whether or not to nest the viewmodels when using a nested object hierarchy. 4429708: Discusses sharing collections between viewmodels directly, but doesn't go into detail. List item: Discusses managing multiple selections within a single viewmodel.

• A Delphi Custom Control: A TRichEdit with a TLabel Above It

  - by doubleu

  Hello, I want to create an custom control (descendant of TRichEdit). I simply want add some text above the editfield. I've created my own control and I override the constructor to create a TLabel for the caption. It works, but my problem: How is it possible to move the label above the richedit? When I set Top := -5 the label begins to disappaer. Here's the code of the constructor: constructor TDBRichEditExt.Create(AOwner: TComponent); begin inherited; lblCaption := TLabel.Create(self); lblCaption.Parent := parent; lblCaption.Caption := 'Header'; lblCaption.Top := -5; end; I think it's logic that the label disappaers since the richedit is the parent. I've tried lblCaption.Parent := self.parent; To make the form which owns the richedit the parent - but this dosn't work... How could I achieve this? Thank you all!

• Can I write a .NETCF Partial Class to extend System.Windows.Forms.UserControl?

  - by eidylon

  Okay... I'm writing a .NET CF (VBNET 2008 3.5 SP1) application, which has one master form, and it dynamically loads specific UserControls based on menu click, in a sort of framework idea. There are certain methods and properties these controls all need to work within the app. Right now I am doing this as an Interface, but this is aggravating as all get up, because some of the methods are optional, and yet I MUST implement them by the nature of interfaces. I would prefer to use inheritance, so that I can have certain code be inherited with overridability, but if I write a class which inherits System.Windows.Forms.UserControl and then inherit my control from that, it squiggles, and tells me that UserControls MUST inherit directly from System.Windows.Forms.UserControl. (Talk about a design flaw!) So next I thought, well, let me use a partial class to extend System.Windows.Forms.UserControl, but when I do that, even though it all seems to compile fine, none of my new properties/methods show up on my controls. Is there any way I can use partial classes to 'extend' System.Windows.Forms.UserControl? For example, can anyone give me a code sample of a partial class which simply adds a MyCount As Integer readonly property to the System.Windows.Forms.UserControl class? If I can just see how to get this going, I can take it from there and add the rest of my functionality. Thanks in advance! I've been searching google, but can't find anything that seems to work for UserControl extension on .NET CF. And the Interface method is driving me crazy as even a small change means updating ALL the controls whether they need to 'override' the method or not.

• Questions about openid and dotnetauthentication

  - by chobo2

  Hi I am looking into openid and dotnetauthentication library. However I still go some outstanding questions. the id that comes back is that unique for each user? Can I store this id in a database as the userId(currently this field is a primary key and unique identifier) I read that you can try to request information such as email address but you may not give it to you. What happens if you need this information? I think it kinda sucks if I have to popup another field right away and ask for their email address and whatever else fields I need. Sort of seems to defeat the purpose a bit as I always considered a benefit of openid is that you don't have to fill out registration forms. Is it better to only have some predefined choices(google,yahoo,openid,facebook). Then letting them type in their own ones(ie gray out the field to let them type in a url). I am thinking of this because it goes back to point number 2 if they type in a provider that does not give me the information that I need I am then stuck. How do you a log person out? Do you just kill the form authentication ticket?
