• Best practices for querying an entire row in a database table? (MySQL / CodeIgniter)

  - by Walker

  Sorry for the novice question! I have a table called cities in which I have fields called id, name, xpos, ypos. I'm trying to use the data from each row to set a div's position and name. What I'm wondering is what's the best practice for dynamically querying an unknown amount of rows (I don't know how many cities there might be, I want to pull the information from all of them) and then passing the variables from the model into the view and then setting attributes with it? Right now I've 'hacked' a solution where I run a different function each time which pulls a value using a query ('SELECT id FROM cities;'), then I store that in a global array variable and pass it into view. I do this for each var so I have arrays called: city_idVar, city_nameVar, city_xposVar, city_yposVar then I know that the city_nameVar[0] matches up with city_xposVar[0] etc. Is there a better way?

• how to format date when i load data from google-app-engine..

• Getting COM object to run in Vista

  - by rainslg

  We expose an interface to our simulation software using a COM/ActiveX object. This worked just fine in XP, but in Vista, we get "Error 429: ActiveX can't create object" when a VB client executes CreateObject(). The COM object has been registered by hand so that the Vista Registry is identical to XP's Registry. I run the VB interface from a DOS window that I started using "Run As Administrator". The client is correctly accessing and reading the Registry as I walk through using the debugger in VB, so it's apparently not a security setting, as near as I can tell. I have also loaded the files into VS2005 (the object was originally created in VS6) and rebuilt them to get a later ATL version, but that hasn't helped - we still get the 429 error. Is this a symptom of UAC problems, or should I be looking for something deeper?

• How do i call bash script function using exec function by passing parameter in php?

It directly goes to the last step of if condition and prints "Please setup a database first. Don't forget to assign a database user!". It cant enter it in if condition and directly goes to else condition. so please help me?

• Is there a standard practice for synchronizing SQL Server tables?

  - by EngineeringAutomation

  I've written an application that retrieves pricing and part options from a SQL database to generate a 3D Model of the product and create a sales proposal. My client likes it so much they want to be able to use it on laptops in the field now. The catch is, they won't have an internet connection. I'm considering setting up a SQLite database as part of the standard installation. The SQLite database on each laptop will synchronize with the main database when the internet connection is re-established. Are there best practices regarding synchronizing SQL tables like this? Are there any pitfalls I should consider? I'm open to all options. Thank you.

• jQuery Validation Plugin - Enable 'Eager' Validation only after and Invalid Submit

  - by Ryan Fitzer

  By default, if a user enters a value in a field, the 'eager' validation kicks in. Is there any way to disable 'eager' validation before submit and then enable it after an invalid submit has happened? I've used $.validator.setDefaults() to initially set the onkeyup and onfocusout properties to false. In the invalidHandler method I rerun the $.validator.setDefaults(), setting onkeyup and onfocusout properties to true. No luck with this approach. Basically, I only want the 'eager' validation to take place after the user tries to submit an invalid form. Thanks for any help.

• Website settings for running visual web as root?

  - by Curtis White

  Scott Gu explains how to run visual web developer using a root path, here: http://weblogs.asp.net/scottgu/archive/2006/12/19/tip-trick-how-to-run-a-root-site-with-the-local-web-server-using-vs-2005-sp1.aspx This worked exactly as he described in one instance for me. But, today I do not see this option. More over, I do not think I have a solution file, and I think that has something to do with it. I'm aware there are web application projects and web site model, and web site model is basically just a "directory". But can web site model, also, have a solution file for this setting or not a solution file? What determines that? I am interested in using this method on on a web site, i.e directory only model.

• Empty page instead of custom tomcat error page

  - by Alexander

  My setting: Apache 2.2 + Tomcat 6.0 @ Windows 2008 R2 64bit static webpages: / servlet: /foo tomcat and apache are connected by mod_jk 404.jsp is placed in tomcat\webapps\ROOT tomcat\conf\web.xml: <error-page> <error-code>404</error-code> <location>/404.jsp</location> </error-page> apache\conf\extra\httpd-ssl.conf: JkMount /foo/* worker1 JkMount /404.jsp worker1 When I open https://...../404.jsp my custom error page is displayed. But when I open https://...../foo/nonexisting.html an empty page is displayed. If I remove the <error-page>...</error-page> code from web.xml and open https://...../foo/nonexisting.html then tomcats own 404 is displayed. Any hints?

• Multiple actions upon a case statement in Haskell

  - by Schroedinger

  One last question for the evening, I'm building the main input function of my Haskell program and I have to check for the args that are brought in so I use args <- getArgs case length args of 0 -> putStrLn "No Arguments, exiting" otherwise -> { other methods here} Is there an intelligent way of setting up other methods, or is it in my best interest to write a function that the other case is thrown to within the main? Or is there an even better solution to the issue of cases. I've just got to take in one name.

• How to monitor MySQL query errors, timeouts and logon attempts?

  - by Abel

  While setting up a third party closed source CMS (Sitefinity) the setup doesn't create all tables and procedures necessary to run it. The software lacks a logging system itself and it made me wonder: could I trace and monitor failing SQL statements from MySQL? This serves more than only the purpose of solving my issue with Sitefinity. More often I wonder what's send to the MySQL server, not wanting to dive into the software products or setup a debugging environment etc. I tried JetProfiler (only performance) and looked through a few others, but although they monitor a lot, they don't monitor query failures, timeouts or logon attempts. Does anyone know a profiler, tracer, monitoring tool, commercial or free, that can show me this information?

• Program skips code after trying to parse XML in VB.NET

  - by Bead

  I'm trying to parse some XML (html) I downloaded using WebRequest.Create() and then read it. However after loading the XML file using LoadXml(string), anything else I execute doesn't work. Setting a breakpoint on anything afterwards doesn't work and it doesn't break. I tried catching exception but none are occurring, so I'm not sure what the problem is. Here is my code: Dim reader As StreamReader = New StreamReader(HTTPResponse.GetResponseStream()) Dim xDoc As XmlDocument = New XmlDocument() xDoc.LoadXml(reader.ReadToEnd()) Dim omfg As String = xDoc.ChildNodes().Item(0).InnerText() Dim name As XmlNodeList = xDoc.GetElementsByTagName("div") Dim jj As Integer = name.Count For i As Integer = 0 To name.Count - 1 MessageBox.Show(name.Item(i).InnerText) Next i Anything after the "xDoc.LoadXml(reader.ReadToEnd())" doesn't execute.. Any ideas on this? My XML does have some whitespace at the beginning, I don't know if that is causing the problem...

• Java Socket fails to transmit data over the network

  - by Mark Griffin

  I'm experiencing a bizarre problem with sockets between a Java Knopflerfish client bundle and a PHP (CLI, not web) server. The client/server pair work fine when both are located on the localhost, and all data is transmitted successfully. However, when the Java client exists on a different machine, connections to the server are successful, but no data is received by the PHP script. Packet analysis confirms that the data sent by the Java client is received on by the server - PHP just seems to have problems getting its hands on it. As a further note, I've done some tests with telnet as the client. The PHP server script receives all data fine from any host. This leads me to believe that the problem has something to do with the way java is setting up the socket or that there is some networking issue that I'm not familiar with. Any thoughts would be appreciated. Can post code samples if desired.

• Top techniques to avoid 'data scraping' from a website database

  - by Addsy

  I am setting up a site using PHP and MySQL that is essentially just a web front-end to an existing database. Understandably my client is very keen to prevent anyone from being able to make a copy of the data in the database yet at the same time wants everything publicly available and even a "view all" link to display every record in the db. Whilst I have put everything in place to prevent attacks such as SQL injection attacks, there is nothing to prevent anyone from viewing all the records as html and running some sort of script to parse this data back into another database. Even if I was to remove the "view all" link, someone could still, in theory, use an automated process to go through each record one by one and compile these into a new database, essentially pinching all the information. Does anyone have any good tactics for preventing or even just dettering this that they could share. Thanks

• Set bold rows in a QTreeView

  - by taynaron

  I have a custom subclass of a QTreeView in a pyqt application. I'm trying to give the user the ability to highlight and "lowlight" (for lack of a better term) rows. Highlighted rows should have bold text and (optionally) a different background color. Any ideas? I'm considering StyleSheets as an option, but have so far been unable to get that to work. If I set the QTreeView's stylesheet: self.setStyleSheet("QTreeView::item:selected {border: 1px solid #567dbc;}") I can't figure out how to manually enable 'states' that would keep only the desired rows at a particular state. If I try setting an individual item's stylesheet: #modelIndex is a valid QModelIndex modelIndex.internalPointer().setStyleSheet() I get a segfault. I'm not convinced stylesheets are the way to go, I'm open to all ideas. Thanks!

• In native C++, how does one use a SqlCe .sdf database?

  - by Omer Sabic

  Is there a simple way, without .NET? I've found some libraries but none for SqlCe 3.5. There is http://sqlcehelper.codeplex.com/ but it's far from done, since a major feature like using a password is not yet implemented. I've looked at the source and it uses OLEdb to handle the database. The offical Microsoft Northwind example (that is shipped with SQL Compact 3.1, but not with 3.5) also doesn't work, I've tried setting it up with no success. Actually I don't have a sample working code. Was anyone able to set it up paired with a passworded .sdf? What are the alternatives? Thanks.

• .NET Setup Package Installer

  - by Duncan

  Hi, I have a .NET 3.5 Setup Package Project which installs my application successfully. The setup package deploys a number (around 70) custom files for use from within the application. From time to time I have the requirement of deleting some of these files, however upon restarting the executable, it automatically runs a portion of the Setup MSI again, and re-installs these files. The only way I can achieve my desired result at the moment is to delete the files after starting the executable. I have looked through the attributes on the files in the setup package such as Vital and PackageAs, however cannot seem to identify the required setting to achieve this. Does anybody have any idea what is needed to acheive this ? Much thanks

• Can't find .Net 2.0 XML Schema

  - by Zach Smith

  I'm currently setting up an application config for a WPF application written in .Net 4.0. The connection string in the app.config is encrypted like so: <connectionStrings configProtectionProvider="DataProtectionConfigurationProvider"> <EncryptedData> <CipherData> <CipherValue>CypherValue</CipherValue> </CipherData> </EncryptedData> </connectionStrings> To use the EncryptedData element I need to include the XMLNS "http://schemas.microsoft.com/.NetConfiguration/v2.0". Attempting to include it produces an error as the schema cannot be found. Is there a way to include the schema or perhaps a different element I could use instead of EncryptedData?

• Globbing with MinGW on Windows

  - by Neil Butterworth

  I have an application built with the MinGW C++ compiler that works something like grep - acommand looks something like this: myapp -e '.*' *.txt where the thing that comes after the -e switch is a regex, and the thing after that is file name pattern. It seems that MinGW automatically expands (globs in UNIX terms) the command line so my regex gets mangled. I can turn this behaviour off, I discovered, by setting the global variable _CRT_glob to zero. This will be fine for bash and other sensible shell users, as the shell will expand the file pattern. For MS cmd.exe users however, it looks like I will have to expand the file pattern myself. So my question - does anyone know of a globbing library (or facility in MinGW) to do partial command line expansion? I'm aware of the _setargv feature of the Windows CRT, but that expands the full command line. Please note I've seen this question, but it really does not address partial expansion.

• Programmatically allow write access for a Registry key

  - by Kerido

  Hi everybody, I need to programmatically modify the Access Descriptors on a known Registry key during product installation. The way I want it to work is: The installer is run in Administrative mode. A Registry key is created. A function (the one I need) queries the ACL from the key. If this function finds that the group 'Users' already has write access, nothing should be done. If not, it should add a new permission allowing write access to the 'Users' group. The permissions are saved for the Registry key. This question is similar to Setting Registry key write permissions using .NET, however, I need a C++/Win32 implementation. Thanks in advance

• How can I modify objects inside frames with AS3 in a permanent way?

  - by curro

  I have a MovieClip symbol created with flash in a fla file library. There is a textfield in frame one of this movieclip's timeline . There is another frame in the movieclip timeline. There is a custon class definition for this symbol. It is a flipping card in a memory game. I access the textfield by going to frame 2 (gotoAndStop(2)) and setting the textfield's text property ( this.field.text = "hello" ). However if I go to frame 1 and then return to frame 2, the text becomes the original one in the library's symbol. I have to modify the text propery again in a showFace method I've written. Besides, I cannot pass parameters in the constructor because it is a symbol in the library and that would give errors. I find this behaviour of flash extremely weird. Is there a way I can set properties inside frames permanently? Thank you

• Have Rails 2.3.x ignore the i18n gem

  - by Jared

  I have a Rails 2.3.5 project that uses the localization features of Rails. I also happen to have Rails 3 beta installed (which depends on the i18n gem). Rails 2.3.5 will happily handle localization on it's own (without i18n installed), however if the i18n gem is available, it makes use of it. Recently I upgraded my gems and now have version 0.3.7 and 0.4.0 of i18n installed. Rails, of course, wants to load and use the latest version which is causing errors in my project. I tried setting the gem version to 0.3.7 which gets around the errors in the web app. However, we're using resque and resque_mailer to delay the sending of messages. When the worker picks up the mailer job from the queue, it ignores my config.gem requirement in environment.rb and uses version 0.4.0 anyway. Ideally, I'd like to tell Rails to just not use the i18n gem at all. How do I do that?

• List service and services status under Win-7

  - by Ronaldo Junior

  I have a service monitor app that monitors the status of three other servers app - you know those kind of green, red status stuff, start, stop, etc. The problem is that it shows the wrong state in Windows 7 even if the user is the administrator. The start, stop buttons are disabled and the install button enabled, the status color is grey which is also wrong. The start button should be enabled with the service status showing green - the apps are running. If the application is run with the setting "run as administrator" then it behaves normally. The application is written in Delphi 7 and works perfectly in other versions of Windows. This line of code: OpenSCManager(PChar(sMachine),Nil,SC_MANAGER_ALL_ACCESS) always return 0 under Win7, causing the problem. Any ideas and if possible, any workaround apart from "run as administrator". Regards Ronaldo

• How to use less memory while running a task in Symfony 1.4?

  - by Guillaume Flandre

  I'm using Symfony 1.4 and Doctrine. So far I had no problem running tasks with Symfony. But now that I have to import a pretty big amount of data and save them in the database, I get the infamous "Fatal Error: Allowed memory size of XXXX bytes exhausted" During this import I'm only creating new objects, setting a few fields and saving them. I'm pretty sure it has something to do with the number of objects I'm creating when saving data. Unsetting those objects doesn't do anything though. Are there any best practices to limit memory usage in Symfony?

• Pull down UIToolbar above UIWebView inside UIScrollView

  - by Nick VanderPyle

  I'd like to display a toolbar above a UIWebView but hide the toolbar until the person "pulls it down". The same functionality can be seen in Safari on the iPhone. When the page loads, the toolbar containing the address is hidden. You must pull it down. In Safari it's possible to scroll up and eventually see the toolbar or scroll down through the page contents. I've tried placing a UIToolbar and UIWebView inside a UIScrollView but it didn't work. I've tried setting the UIScrollView to the size of the toolbar and webview combined, but that didn't work. - (void)viewDidLoad{ CGSize size = CGSizeMake(webView.frame.size.width, toolBar.frame.size.height + webView.frame.size.height); [scrollView setContentSize:size]; } How should I go about doing this?
