  • Check for state change in objects using serialization?

    - by sev7n
    I have a form that is bind to an object, and when the user trying to leave the form, I want to warn them if anything on the form has been changed, and prompt them to save. My question is, is there any way to achieve this without implementing IComparar for all my classes in the binded object? I was thinking if there is a way I can serialize my object when loading the form, and do a simple comparison against the change object that also get serialized. Something like a string comparison. Hope that make sense, Thanks

  • Why does the last row of my tableview not align to the bottom of the screen

    - by Liam
    I have a view which consists of a tableview and a navigation bar. For my tableview I have implemented a 'Load more' row which will load current + pagesize every time it is clicked The way the loading works is very simple, every time it is clicked I just request the amount of rows I want to display e.g. 5, 10, 15 and so on. This request populates an array and I call [self.tableView reloadData] The issue I am experiencing is that when I go to the tableview the first time, it correctly loads and displays the tableview. However, if I 'Load more' it returns the correct amount and displays the correct number of cells but the last cell will not fit properly at the bottom of the screen, about 1/2 of it (or roughly the size of the navigation bar of the cell) appears below the bottom of the screen. I thought it was sufficient to just tell the tableview to reload itself. Do I need to use [self.tableView insertRowsAtIndexPaths ...] to do this.

  • Injecting a dependancy into a base class

    - by Jamie Dixon
    Hey everyone, I'm on a roll today with questions. I'm starting out with Dependency Injection and am having some trouble injecting a dependency into a base class. I have a BaseController controller which my other controllers inherit from. Inside of this base controller I do a number of checks such as determining if the user has the right privileges to view the current page, checking for the existence of some session variables etc. I have a dependency inside of this base controller that I'd like to inject using Ninject however when I set this up as I would for my other dependencies I'm told by the compiler that: Error 1 'MyProject.Controllers.BaseController' does not contain a constructor that takes 0 argument This makes sense but I'm just not sure how to inject this dependency. Should I be using this pattern of using a base controller at all or should I be doing this in a more efficient/correct way?

  • Factory vs instance constructors

    - by Neil N
    I can't think of any reasons why one is better than the other. Compare these two implementations: public class MyClass { public myClass(string fileName) { // some code... } } as opposed to: public class MyClass { private myClass(){} public static Create(string fileName) { // some code... } } There are some places in the .Net framework that use the static method to create instances. At first I was thinking, it registers it's instances to keep track of them, but regular constructors could do the same thing through the use of private static variables. What is the reasoning behind this style?

  • Download and replace Android resource files

    - by Casebash
    My application will have some customisation for each company that uses it. Up until now, I have been loading images and strings from resource files. The idea is that the default resources will be distributed with the application and company specific resources will be loaded from our server after they click on a link from an email to launch the initialisation intent. Does anyone know how to replace resource files? I would really like to keep using resource files to avoid rewriting a lot of code/XML. I would distribute the application from our own server, rather than through the app store, so that we could have one version per company, but unfortunately this will give quite nasty security warnings that would concern our customers.

  • QtWebkit and hasPendingEvents() always True

    - by Deorf
    Hello. I use project webkit2png (slightly appended) to take screenshots in Linux. On the server running the latest version QtWebkit and Python 2.6 On some sites (eg 118114.cn) problem and the application hangs forever. Debug shows that the problem in this code snippet: while self.__loading:    if timeout 0 and time.time() = cancelAt:       raise RuntimeError("Request timed out on %s" % url)    while QApplication.hasPendingEvents():       QCoreApplication.processEvents() Full version of the source code is available here (lines 270-275) Somehow Loading-event hangs and hasPendingEvents can not be False. Most of the screenshots are created normally, but sometimes due to some URL drops my app: ( Does anyone know how to solve this problem and why the event hangs?

  • How do I get the current Application Name (in terms of IIS) in a classic asp Web application

    - by Mr AH
    I have a classic asp application which retrieves the current application name and sets an Application variable containing that name. This name is important (I wont go into why) and is essentially the friendly name in IIS. The problem is, the implementation used to get this name is flawed, it a) assumes the home directory contains the string wwwroot, and b) assumes the folder name is the same as the application name. I can no longer guarantee these conditions. I would have thought the application name is know at run-time but I can't seem to find it in either Session or Application variables (at application start up entry point in global.asa). Any ideas?

  • Getting 0x80131902 when calling COM+ component

    - by Kyle W
    I created a COM+ component in .Net. It needs to use a configuration file, so I've created a directory with an application.manifest and application.config file and set that as the Application Root Directory. Now when I try to create an instance of that object, I get the following HRESULT: 0x80131902. I can't seem to find exactly what this means, except that there is a problem loading the app-domain. If I don't set the Application Root Directory, it loads just fine (but doesn't have access to the config).

  • how does "recent history" work on sites for php? (PHP)

    - by ggfan
    I'm not sure if there is an explanation on SO for beginners, but if so, could you provide the links. I am interested in creating a "recent viewed" function that shows what links they clicked on before. I'm not sure if this is the 'correct' way to do it, but this is what I have so far... user clicks on a link(say ad.php?posting_id=12). if the user doesn't click on the link, no cookie or session is stored for the link if the user clicks on the link, it sets a cookie for $_cookie['ad.php?posting_id=22'] Each time the user clicks, more cookies are set In the recent viewed function, it gets all the $_cookie variables and displays them. if the user wants to clear the history, just destroy all the cookies I'm not sure if this is the way to do it, but is the viable? If not, what are the steps to create a "recent viewed" function

  • C++ associative array with arbitrary types for values

    - by Gerald Kaszuba
    What is the best way to have an associative array with arbitrary value types for each key in C++? Currently my plan is to create a "value" class with member variables of the types I will be expecting. For example: class Value { int iValue; Value(int v) { iValue = v; } std::string sValue; Value(std::string v) { sValue = v; } SomeClass *cValue; Value(SomeClass *v) { cValue = c; } }; std::map<std::string, Value> table; A downside with this is you have to know the type when accessing the "Value". i.e.: table["something"] = Value(5); SomeClass *s = table["something"].cValue; // broken pointer Also the more types that are put in Value, the more bloated the array will be. Any better suggestions?

  • Zend Framework problem with adding CSS files

    - by priktop
    Hi, I have a small problem when loading CSS files with the Zend Framework. This is my code: <?php echo $this->headLink()->prependStylesheet($this->baseUrl().'/css/reset.css'); ?> <?php echo $this->headLink()->prependStylesheet($this->baseUrl().'/css/main.css'); ?> When i open the page in my browser, it puts the main before the reset. This way i get my page unstyled because it gets reset by the reset.css. Any suggestions? Thanks.

  • Is it ok to store large objects (java component for example) in an Application variable?

    - by DustMason
    I am developing an app right now which creates and stores a connection to a local XMPP server in the Application scope. The connection methods are stored in a cfc that makes sure the Application.XMPPConnection is connected and authorized each time it is used, and makes use of the connection to send live events to users. As far as I can tell, this is working fine. BUT it hasn't been tested under any kind of stress. My question is: Will this set up cause problems later on? I only ask because I can't find evidence of other people using Application variables in this way. If I weren't using railo I would be using CF's event gateway instead to accomplish the same task.

  • Get Data from Windows Form into C# program

    - by Jimmy
    I want my C# program to collect data. Then, when the OK button is clicked, I want this data to be loaded into my program -- such as into variables in Main(), or into data members of a class I have constructed, and I want the form to then go away -- not be hidden, but actually closed. Alas, read as I might in the book I have, the data collected by the form stays in the form, execution proceeds within the form, and the same form is used to display the result of the program's computations. Sheesh. All I want is to capture the form's information, close the form and proceed with my program. I would appreciate some tips on geting data from a form into Main() or into a class's data members. Thanks, Lucky

  • ShapeFile with Z Co-ordinates

    - by ace_mccloud
    I have 3 shapefiles, two of them wihtout the Z Co-ordinates elevation but 1 of them has a Z co-ordinate elevation. I can load two ShapeFiles into my SQL Server Database which does not have Z Co-ordinates. But I am having issue loading the Z Co-ordinate file into the database. I have been reading different forums and got a suggestion that I need to trim the Z coordinates(chnage 3D to 2D) to load into the database. I was just wondering how can I achieve this? Can anyone suggest free tools or any method to do the same? Cheers, Rushir

  • java: communication between threads

    - by TRU7H
    I'm making a little java game in which I would have two threads (well as the FIRST step towards multithreading...), one for the logic and one for the drawing. So my question is: How can I make those two communicating which each other? Requirements: accessing variables and object from a another thread syncing them so they each complete a same number of "loops" in the same time. (the logic calculates and then the another one draws the results and the loop begins again...) So how is this achievable in java? Thanks in advance!

  • Getting Database Data to the client side.

    - by Toby Allen
    I'm sure this has been asked a million times, but what is the accepted approach to this? I have been writing php code for a while and up until recently I only copied+pasted javascript code, but now with help from YUI I've begun to understand javascript and want to use it more in an existing web app I have. I want to get various amounts of data from databases etc to the clientside javascript. I have access to this data in my php pages when loading. What is the correct way to get this data to my client side script. Generate clientside javascript in my php or smarty template files inserting the data where I need it? Use an Ajax call to retrieve the information I need from a php file - returning JSON data? Generate a JSON data construct of the data needed by the page and either return it via a script inclusion or dumping it to the generated page? Something really obvious I haven't thought of.

  • Netbeans 7.2 not starting

    - by Buddhika Ariyaratne
    I recently installed Netbeans 7.2 beta and it worked fine. Then I installed Netbeans 7.2 final release on top of beta and during the installation, Netbeans 7.1 and Netbeans 7.12 were there. Now when I launch Netbeans, it does not go beyond "loading modules" stage. Simply the Netbeans screen disappear few seconds after the launch. Then I did the following. Uninstalled all the Netbeans versions and re-installed Netbeans 7.2 Deleted AppData/Netbeans folder Deleted User/.nbi folder Searched the registry and deleted Netbeans related entries. (But only one entry was found) Deleted Netbeans Folder in Program Files folder. Uninstalled and Re-installed in a separate drive. Uninstalled and Re-installed under another user account. None of the above worked, the only thing I did not try was to re-install the Windows XP operating system. It there any option to try before re-installing the operating system?

  • T4MVC and Ajax method with parameter

  • Animation on single UIWebView

    - by Shri
    I have searched quite a bit(sample one, Sample two) but cant seem to get the correct answer. I have a webview on my XYZ view controller class. When i press on a button, it takes an URL from an array and re-loads the same webview. Now I need to do the flip book animation on it. Same webview should be reloaded. That is the webview should rotate around its own axis 180/360 degree while the loading of next url is going on. Is this possible?

  • Treeview Slow in IE?!?!

    - by Mike
    I have a treeview with around 200 records that needs to be fully expanded at all times (so no loading on demand). It is inside of an update panel with the updatemode set to conditional. There are other update panels on the page as well that are set to conditional. Depending on user actions the tree may need to be rebuilt by calling databind and updating the updatepanel. Everything works fine in firefox, longest postback about 2 seconds. With IE I have to wait up to 30 seconds sometimes and the action may have nothing to do with the tree just changing a dropdown in its own updatepanel takes forever. I have considered the size of viewstate and just raw HTML generated may be causing the delay but wouldn't that effect both browsers? Anyone have anyideas what is making it so slow in IE??? Thanks!

  • How can I determine whether xml serializer can serialize a file

    - by ldsenow
    Hi, How can I determine whether xml serializer can serialize a file which is in a shared location and monitored by a file monitor. The file monitor has a list of parsers which are used to parse files in the shared folder. Once a file gets dropped into the folder, the file monitor will ask the registered parsers whether any of them can handle this file, if yes, the monitor will move the file out from the shared folder and assigns the task to the parser. Since some of the files are quite big, so I need to have a quick check on each parsers. How can I determine my xml parser can serialize the file without loading the full file into the memory?

  • How to structure web application with part of it being secured (SSL)

    - by spirytus
    What is the common pattern to structure web application where part of it has to be secured. So lets say I have page_a and page_b which do not need to be secured, although should display login information (login fields or login details once user logged in). This web app. also would have secured pages (admin, checkout or similar) secure_page_c and secure_page_d. My questions are: What is the common folder structure for such assuming I code in php with no frameworks? Also how shall I deal with session variables in case user navigates lets say from secure_page_b to non secure page_a or vice versa? What else might be a problem and should be considered when coding that kind of app in php? Thank you all for any suggestions

  • better for-loop syntax for detecting empty sequences?

    - by Dmitry Beransky
    Hi, Is there a better way to write the following: row_counter = 0 for item in iterable_sequence: # do stuff with the item counter += 1 if not row_counter: # handle the empty-sequence-case Please keep in mind that I can't use len(iterable_sequence) because 1) not all sequences have known lengths; 2) in some cases calling len() may trigger loading of the sequence's items into memory (as the case would be with sql query results). The reason I ask is that I'm simply curious if there is a way to make above more concise and idiomatic. What I'm looking for is along the lines of: for item in sequence: #process item *else*: #handle the empty sequence case (assuming "else" here worked only on empty sequences, which I know it doesn't)

  • Check the cumulative status of onLoadInit in a for statement

    - by jonobr1
    In a setup like this is it possible to check the cumulative status of all onLoadInit? for(var i:Number = 0; i < limit; i++) { var mcLoader:MovieClipLoader = new MovieClipLoader(); var mclListener:Object = new Object(); mclListener.onLoadInit = function(mc:MovieClip) { trace(i + " is finished loading!"); } mcLoader.addListener(mclListener); mcLoader.loadClip(some_image_path, someMovieClip); } Initially I was thinking that I could pass an array of Boolean's, but I'm not really sure where to add that checkpoint, because a flash frame doesn't keep looping. Would I have to add it to an onEnterFrame()?
