• mysql and .net: when using tableadapters I’m getting MySqlException “insert command denied for user”

  - by Deveti Putnik

  Hi! I am using mysql as db for my asp.net application. Here are the facts: I am using connection string from web.config which has both username and password. I can do SELECT with tableadapter. When I am trying to do INSERT with tableadapter, I am getting "mysqlexception insert command denied for user" error When I try to do INSERT programatically, i.e. using connection, command object, etc. everything is fine. In this case, I'm reading connection string from web.config, too. This can be only applied to GoDaddy hosting, but on local machine I don't have this kind of problems. Can anyone suggest what can I do to make it work on GoDaddy hosting? Regards, D

• C#: Check if administrator has write access to a file

  - by Bilal Aslam

  The Problem: I need to check if a user (local user or domain user, either one is possible) has write access to a file (if you're curious, %windir%\system32\inetsrv\applicationHost.config. This file is protected by Windows and you need to be an administrator to write to it.) My Solution: The general construct is: using (Impersonator impersonator = new Impersonator(domain, username, password)) { try { using (FileStream fs = File.OpenWrite(appHostConfigPath)) { return true; } catch { return false; } } As you can imagine, the Impersonator class is an IDisposible which uses native interop to call LogonUser. Nothing too creative, and it works. Where I am stuck: On Windows OSs with UAC enabled, this function always return false even if the user specified by username is an administrator. Even though my program is running elevated as an administrator, I suspect what's happening is that the impersonated code is running as a limited administrator. Hence, the method is returning false. I don't have any creative solutions to this. Can anyone help?

• Flex: Result event given multiple times

  - by Tom

  Hello everybody!! I am trying to learn Flex and now i have the next code: http://pastebin.com/rZwxF7w1 This code is for my login component. I want to get a special string for encrypting my password. This string is given by my authservice. But when i login i get a multiple times a alert with Done(line 69 in the pastebin code or line 4 in the code on the bottom of this question). But i want that it shows one single time. Does someone know what is wrong with this code? Tom protected function tryLogin():void { encryptStringResult.addEventListener('result', function(event:ResultEvent):void { var encryptString:String = event.result.toString(); Alert.show('Done'); }); encryptStringResult.token = auth.getEncryptString(); }

• Is it possible to put binary image data into html markup and then get the image displayed as usual i

  - by Joern Akkermann

  It's an important security issue and I'm sure this should be possible. A simple example: You run a community portal. Users are registered and upload their pictures. Your application gives security rules whenever a picture is allowed to be displayed. For example users must be friends on each sides by the system, in order that you can view someone else's uploaded pictures. Here comes the problem: it is possible that someone crawls the image directories of your server. But you want to protect your users from such attacks. If it's possible to put the binary data of an image directly into the HTML markup, you can restrict the user access of your image dirs the user and group your web application runs of and pass the image data to your Apache user and group directly in the HTML. The only possible weakness then is the password of the user that your web app runs as. Is there already a possibility?

• "The item you tried to buy is no longer available" storekit error in iphone sdk

  - by aloo

  Hi all, I'm trying to use the StoreKit API in OS3.0 for the iphone to do in app purchase. However, I'm getting the following error when trying to purchase something in the SANDBOX ENVIRONMENT. The item you tried to buy is no longer available [Environment: Sandbox] Here's the code I use to do the payments: SKPayment* payment = [SKPayment paymentWithProductIdentifier:model.productId]; [[SKPaymentQueue defaultQueue] addPayment:payment]; I've also queried storekit for the list of available products and that seems to work just fine returning the same product identifiers that I'm now using to purchase the item. I have all the products setup in iTunes Connect and created a test user. Before debugging the app I signed out of the store in the settings menu and entered my test account and password when debugging my own app. What could be going on here?

• How to change the layout of the CreateUserWizard control?

  - by Bazzz

  How to change just the layout (template) of the CreateUserWizard control programmatically? I would to define another layout (not using the horrid table) but continue to use all the event handling and the creation of the user of the CreateUserWizard control. Just for reference, the following code doesn't work, and produces an unexpected result not representing my Template at all. The "InstantiateIn" method of the ITemplate is not called. public partial class b : System.Web.UI.Page { protected void Page_Init(object sender, EventArgs e) { CreateUserWizard createUserWizard = new CreateUserWizard(); createUserWizard.CreateUserStep.ContentTemplate = new Template(); Panel1.Controls.Add(createUserWizard); } } public class Template : ITemplate { void ITemplate.InstantiateIn(Control container) { container.Controls.Add(new TextBox() { ID = "UserName" }); container.Controls.Add(new TextBox() { ID = "Password" }); container.Controls.Add(new TextBox() { ID = "ConfirmPassword" }); container.Controls.Add(new TextBox() { ID = "Email" }); container.Controls.Add(new PlaceHolder() { ID = "ErrorMessage" }); } } }

• Design Technique: How to design a complex system for processing orders, products and units.

  - by Shyam

  Hi, Programming is fun: I learned that by trying out simple challenges, reading up some books and following some tutorials. I am able to grasp the concepts of writing with OO (I do so in Ruby), and write a bit of code myself. What bugs me though is that I feel re-inventing the wheel: I haven't followed an education or found a book (a free one that is) that explains me the why's instead of the how's, and I've learned from the A-team that it is the plan that makes it come together. So, armed with my nuby Ruby skills, I decided I wanted to program a virtual store. I figured out the following: My virtual Store will have: Products and Services Inventories Orders and Shipping Customers Now this isn't complex at all. With the help of some cool tools (CMapTools), I drew out some concepts, but quickly enough (thanks to my inferior experience in designing), my design started to bite me. My very first product-line were virtual "laptops". So, I created a class (Ruby): class Product attr_accessor :name, :price def initialize(name, price) @name = name @price = price end end which can be instantiated by doing (IRb) x = Product.new("Banana Pro", 250) Since I want my virtual customers to be able to purchase more than one product, or various types, I figured out I needed some kind of "Order" mechanism. class Order def initialize(order_no) @order_no = order_no @line_items = [] end def add_product(myproduct) @line_items << myproduct end def show_order() puts @order_no @line_items.each do |x| puts x.name.to_s + "\t" + x.price.to_s end end end that can be instantiated by doing (IRb) z = Order.new(1234) z.add_product(x) z.show_order Splendid, I have now a very simple ordering system that allows me to add products to an order. But, here comes my real question. What if I have three models of my product (economy, business, showoff)? Or have my products be composed out of separate units (bigger screen, nicer keyboard, different OS)? Surely I could make them three separate products, or add complexity to my product class, but I am looking for are best practices to design a flexible product object that can be used in the real world, to facilitate a complex system. My apologies if my grammar and my spelling are with error, as english is not my first language and I took the time to check as far I could understand and translate properly! Thank you for your answers, comments and feedback!

• Messy bash variable

  - by Kyle

  I'm writing a script to ssh in to a list of machines and compare a variable to another value.. I've run into a problem (I have a couple workarounds, but at this point I'm just wondering why this method isn't working). VAR=ssh $i "awk -F: '/^bar/ {print \$2}' /local/foo.txt" ($i would be a hostname. The hosts are trusted, no password prompt is given) Example of foo.txt: foo:123456:abcdef bar:789012:ghijkl baz:345678:mnopqr I'm assuming it's a problem with quotes, or \'s needed somewhere. I've tried several methods (different quoting, using $() instead of ``, etc) but can't seem to get it right. My script is working correctly using the following: VAR=ssh $i "grep bar /local/foo.txt" | awk -F: '{print \$2}' Like I said, just a curiousity, any response is appreciated.

• jQuery Ajax form submit, to call php login script

  - by Stevie Jenowski

  Thanks for checking out my problem... I'm having trouble submitting a login form via Ajax for a php script to run and return a new set of html items which will be replacing the HTML in #userlinks.... heres what I have so far $("#login_form").submit(function() { return false; }); $('#login_button').click(function(event) { $form = $(this).parent("form"); $.post($form.attr("action"), $form.serialize(), function(data){ $('#userlinks').html(data); }); }); The php script checks for post data of username && password, yet all I'm getting is a page refresh and no changes. Nothing returns unless I turn login_button into a link and change the script a bit... Any help would be appreciated!

• For Loop help In a Hash Cracker Homework.

  - by aaron burns

  On the homework I am working on we are making a hash cracker. I am implementing it so as to have my cracker. java call worker.java. Worker.java implements Runnable. Worker is to take the start and end of a list of char, the hash it is to crack, and the max length of the password that made the hash. I know I want to do a loop in run() BUT I cannot think of how I would do it so it would go to the given max pasword length. I have posted the code I have so far. Any directions or areas I should look into.... I thought there was a way to do this with a certain way to write the loop but I don't know or can't find the correct syntax. Oh.. also. In main I divide up so x amount of threads can be chosen and I know that as of write now it only works for an even number of the 40 possible char given. package HashCracker; import java.util.*; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; public class Cracker { // Array of chars used to produce strings public static final char[] CHARS = "abcdefghijklmnopqrstuvwxyz0123456789.,-!".toCharArray(); public static final int numOfChar=40; /* Given a byte[] array, produces a hex String, such as "234a6f". with 2 chars for each byte in the array. (provided code) */ public static String hexToString(byte[] bytes) { StringBuffer buff = new StringBuffer(); for (int i=0; i<bytes.length; i++) { int val = bytes[i]; val = val & 0xff; // remove higher bits, sign if (val<16) buff.append('0'); // leading 0 buff.append(Integer.toString(val, 16)); } return buff.toString(); } /* Given a string of hex byte values such as "24a26f", creates a byte[] array of those values, one byte value -128..127 for each 2 chars.

• How to make a remote connection to a MySQL Database Server?

  - by MLB

  Hello: I am trying to connect to a MySQL database server (remote), but I can't. I am using an user with grant privileges (not root user). The error message is the following: Can't obtain database list from the server. Access denied for user 'myuser'@'mypcname' (using password: YES) "myuser" is an user I created with grant access. This user allows me to connect locally to every database. I am using the same software versions in both hosts: MySQL Server 4.1 (server) and EMS SQL Manager 2005 for MySQL, edition 3.7.0.1 (client). The point is that I need to connect to the remote server using a different user, not root user. So, how to make the connection? Thanks.

• How do I read CalDAV objects from Google using python/django?

  - by user60626

  I've looked at vObject, iCalendar and the official list of CalDAV libraries, including 3 in python. However, I can't find any code that can get me an event object from a given CalDAV (i.e. google, exchange, etc.) server using a username/password. Most of the django calendar related code uses native code libraries and not WebDAV. An ideal python CalDAV client example would 1) use a given uid/pw, 2) obtain primary calendar and 3) obtain next appointment information (i.e. subject, location, start, end, etc.) Thanks!

• Realtime Twitter Replies?

  - by ejunker

  I have created Twitter bots for many geographic locations. I want to allow users to @-reply to the Twitter bot with commands and then have the bot respond with the results. I would like to have the bot reply to the user as quickly as possible (realtime). Apparently, Twitter used to have an XMPP/Jabber interface that would provide this type of realtime feed of replies but it was shut down. As I see it my options are to use one of the following: REST API This would involve polling every X minutes for each bot. The problem with this is that it is not realtime and each Twitter account would have to be polled. Search API The search API does allow specifying a "-to" parameter in the search and replies to all bots could be aggregated in a search such as "-to bot1 OR -to bot2...". Though if you have hundreds of bots then the search string would get very long and probably exceed the maximum length of a GET request. Streaming API The streaming API looks very promising as it provides realtime results. The API allows you to specify a follow and track parameters. follow is not useful as the bot does not know who will be sending it commands. track allows you to specify keywords to track. This could possibly work by creating a daemon process that connects to the Streaming API and tracks all references to the bot's names. Once again since there are lots of bots to track the length and complexity of the query may be an issue. Another idea would be to track a special hashtag such as #botcommand and then a user could send a command using this syntax @bot1 weather #botcommand. Then by using the Streaming API to track all references to #botcommand would give you a realtime stream of all the commands. Further parsing could then be done to determine which bot to send the command to. Third-party service Are there any third-party companies that have access to the Twitter firehouse and offer realtime data? I haven't investigated these, but here are a few that I have found: Gnip Tweet.IM excla.im TwitterSpy - seems to use polling, not realtime I'm leaning towards using the Streaming API. Is there a better way to get near realtime @-replies for many (hundreds) of Twitter accounts?

• asp.net application install folder

  - by Maximilian Csuk

  Disclaimer: this is not a question about how to install asp.net or an application using it! Hi! I am pretty sure many of you have once installed some kind of forum, blog or CMS (mostly PHP powered applications). All of these contain a folder mostly named "install" where (after you copied the files to the webserver) point your browser to to complete the installation by entering for example database information (servername, username, password, ...). After that, most applications suggest that you delete this folder or at least change the permissions so nobody from the outside can access it anymore. Now to my question: how would you go about that in the asp.net world? I don't really like the "install folder"-approach and I thought there might be a different mechanism for .net/IIS. The person installing my application should be able to enter his database information as painless as possible, which should ultimatively be stored in the web.config file. If it makes a difference, I am using asp.net MVC. Thanks for your help!

• Recommendations for a C++ polymorphic, seekable, binary I/O interface

  - by Trevor Robinson

  I've been using std::istream and ostream as a polymorphic interface for random-access binary I/O in C++, but it seems suboptimal in numerous ways: 64-bit seeks are non-portable and error-prone due to streampos/streamoff limitations; currently using boost/iostreams/positioning.hpp as a workaround, but it requires vigilance Missing operations such as truncating or extending a file (ala POSIX ftruncate) Inconsistency between concrete implementations; e.g. stringstream has independent get/put positions whereas filestream does not Inconsistency between platform implementations; e.g. behavior of seeking pass the end of a file or usage of failbit/badbit on errors Don't need all the formatting facilities of stream or possibly even the buffering of streambuf streambuf error reporting (i.e. exceptions vs. returning an error indicator) is supposedly implementation-dependent in practice I like the simplified interface provided by the Boost.Iostreams Device concept, but it's provided as function templates rather than a polymorphic class. (There is a device class, but it's not polymorphic and is just an implementation helper class not necessarily used by the supplied device implementations.) I'm primarily using large disk files, but I really want polymorphism so I can easily substitute alternate implementations (e.g. use stringstream instead of fstream for unit tests) without all the complexity and compile-time coupling of deep template instantiation. Does anyone have any recommendations of a standard approach to this? It seems like a common situation, so I don't want to invent my own interfaces unnecessarily. As an example, something like java.nio.FileChannel seems ideal. My best solution so far is to put a thin polymorphic layer on top of Boost.Iostreams devices. For example: class my_istream { public: virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) = 0; virtual std::streamsize read(char* s, std::streamsize n) = 0; virtual void close() = 0; }; template <class T> class boost_istream : public my_istream { public: boost_istream(const T& device) : m_device(device) { } virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) { return boost::iostreams::seek(m_device, off, way); } virtual std::streamsize read(char* s, std::streamsize n) { return boost::iostreams::read(m_device, s, n); } virtual void close() { boost::iostreams::close(m_device); } private: T m_device; };

• Using svn with xampp for php projects

  - by idrish

  I have heard a lot about version control and would like to work on it. I read some tutorials about the same. However i am not quite sure how svn works with xampp. I have installed svn, Tortoise svn and made the necessary changes in xampp. For instance i copied the two required modules to c:/xampp/apache/modules and also made changes to the conf file in apache. Here are the changes made in c:/xampp/apache/conf/httpd.conf. # Configure Subversion repository <Location /svn> DAV svn SVNPath “C:\svn” AuthType Basic AuthName “Subversion repository” AuthUserFile “c:\svn_conf\passwd” Require valid-user </Location>t I created the repository at c:/svn and also created the password file. However when i visit http:/localhost/svn i get a 404 page not found error. Where am i going wrong. what am i missing.? Any pointers?? Thanks in advance.

• How to reset Scrapy parameters? (always running under same parameters)

  I've been running my Scrapy project with a couple of accounts (the project scrapes a especific site that requieres login credentials), but no matter the parameters I set, it always runs with the same ones (same credentials). I'm running under virtualenv. Is there a variable or setting I'm missing? Edit: It seems that this problem is Twisted related. Even when I run: scrapy crawl -a user='user' -a password='pass' -o items.json -t json SpiderName I still get an error saying: ERROR: twisted.internet.error.ReactorNotRestartable And all the information I get, is the last 'succesful' run of the spider.

• ASP.net Text Box Enter button pressed hell

  - by Morgeh

  Basically I have an asp.net website with login and search pages. Currently, I have no idea why, when ever a user hits enter in either of the login text boxes (user name/password) or in the Seach text box, the website is redirected to the default page. I have no idea why this is happening, I've tried setting defaultButton on both the panel containing the search and the login panel but that doesnt seem to work. I've also tried catching the key press event with javascript which isnt working either. I have no idea what event is being fired and why, or why it seems to override everything I try to do. Anyone seen anything like this before?

• Issues dismissing keyboard conditionally with on iPhone

  - by Chris

  I have an app that has a username and password field. I want to validate the input before the the user is allowed to stop editing the field. To do that, I'm using the textFieldShouldEndEditing delegate method. If the input doesn't validate I display a UIAlertView. This approach works as advertised - the user cannot leave the field if the input doesn't validate. To have the done button on the keyboard dismiss the keyboard, I call resignFirstResponder on the textfield. The issue I have is the alert is being called twice. How do I keep the alert from showing twice?
