• Massive SQL issue shutting down our site.

  - by Pselus

  Our website has started timing out like crazy today. All of our clients are finding it unusable. The only error we can seem to trace down as a potential problem is this: SQLAllocHandle on SQL_HANDLE_DBC failed Error ASP Description Error Category Microsoft OLE DB Provider for ODBC Drivers I have no idea what it means or how to go about fixing it. Anyone ever encountered this error before? Currently, you can log in to our site, but then once you go to do anything else, you find yourself logged out or nothing happens. We have a lot of Ajax going on so the "nothing happens" probably has to do with the Ajax pages not loading properly due to logouts and so nothing displays to the user. Like I said, I'm at a loss. Anyone have any advice on this error?

• How to secure connection between PHP and Android

  - by Elad Cohen

  I am developing an application for the Android that requires a connection with PHP pages in order to add sensitive data to a database that will affect the application. Since it's very easy to reverse engineer an android app, one can simply find the url where the data is sent to and manipulate it. I thought about creating a registration based on IMEI, but one can still able to manipulate it for his malicious purposes. I have also checked OAuth but I didn't really understand how it works and if it can help in my condition. What can I do to fully secure my application? Thanks in advance! EDIT: By the way, what I am mostly trying to achieve here is to make sure the requests are being sent from an Android and not from any other device.

• Python Framework for small website

  - by mvid

  I am planning a small, simple website to showcase myself as an engineer. My preferred language is Python and I hope to use it to create my website. My pages will be mostly static, with some database stored posts/links. The site will be simple, but I would like to have freedom in how it operates. I plan on using CSS/JS for the design, so I really just need an easy way to throw a small amount of content around. Some frameworks I have come across: Flask cherry.py Pinax Are there any suggestions? Does anyone have any experience with Python on small/hobby websites?

• Filter elements in PropertyGrid

  - by serhio

  In System.Windows.Forms there are a PropertyGrid that displays properties of an attached object. Let's say MyTextBox : TextBox. Now, I would like to display on it some MyTextBox properties, say only Size, Location and my custom property Date. More that than, I would like to be able to change the real property names, say "Dimension", "Location" and "Starting Date". I saw two projects on this subject : first and second, but first does not work well(for browsable properties), and the second seems to add an event for each property changes, this is not acceptable.

• Jface's CheckboxTreeViewer how to set initial selection

  - by Hypercube

  Hello. This question may sounds trivial, but i am struggling with the issue, so, please help if u can. So, here it is : i am using a CheckboxTreeViewer for some good reasons. I've google-it for some class usages, and i am currently able to check/uncheck all the childrens of a selected node, and to preserve the selection after a live search with a custom implementation of the StyledCellLabelProvider provider. All good so far. However, so far i am unable to programatically select one or more elements of the tree viewer after i display the widget and call the setInput() method of the viewer. So, let's assume for instance that the tree will have 10 main nodes, and 5 leafs on node 6. My question is how do i set the checked state of the 3rd leaf? Thank u.

• Alternate datasource for django model?

  - by slypete

  I'm trying to seamlessly integrate some legacy data into a django application. I would like to know if it's possible to use an alternate datasource for a django model. For example, can I contact a server to populate a list of a model? The server would not be SQL based at all. Instead it uses some proprietary tcp based protocol. Copying the data is not an option, as the legacy application will continue to be used for some time. Would a custom manager allow me to do this? This model should behave just like any other django model. It should even pluggable to the admin interface. What do you think? Thanks, Pete

• jQuery/Javascript framework efficiency

  - by Russell

  My latest project is using a javascript framework (jQuery), along with some plugins (validation, jquery-ui, datepicker, facebox, ...) to help make a modern web application. I am now finding pages loading slower than I am used to. After some js profiling (thanks VS2010!), it seems a lot of the time is taken procesing inside the framework. Now I understand the more complex the ui tools, the more processing needs to be done. The project is not yet at a large stage and I think would be average functions. At this stage I can see it is not going to scale well. I noticed things like the 'each' command in jQuery takes quite a lot of processing time. Have others experienced some extra latency using JS frameworks? How do I minimise their effect on page performance? Are there best practices on implementation using JS frameworks? Thanks

• Apache is running but there is no page displayed

  - by Michael Ozeryansky

  I am on a Mac OSX and I am using the built in PHP and Apache2. I have been setting up MySQL and finally when I got MySQL working my local site won't display. Do note that I did have the web server running and delivering PHP enabled pages, just no database connection. But my question is not about MySQL. I have changed various settings in the 'http.conf' file, and I have the line: '127.0.0.1 localhost' in my hosts file. I also have other alias' pointing to 127.0.0.1. I have checked everything I could about Apache and I have made sure that any message in the error_log is ok. I currently have my errorLevel set to debug, so I get all the messages. At this point (HOURS of self fixing) I think I need help. What can I provide for someone to figure this out with me. Thanks.

• Why is there so much "magic" in Perl?

  - by eugene y

  I'm looking through perlop and perlsub pages of the Perl manual. There are many references about "magic" and "magical" here (just search any of them for the "magic"). I wonder why is Perl so rich in them. Some examples: print ++($foo = 'zz') # prints 'aaa' printf "%d: %s", $! = 1, $! # prints '1: Operation not permitted' use warnings; my $i; print $i++ # no warning for uninitialized value while (my $line = <FH>) { ... } # $line is actually tested for definedness

• Specify Windows Service Name on install with Setup Project

  - by sympatric greg

  Objective: In support of a Windows Service that may have multiple instances on a single machine, use a Setup Project to create an MSI capable of: Receiving user input for Service Name Installing service Serializing Service Name from 1 (so that the proper name can be used in logging and uninstall) My initial hope was to set Service Name in App.config (and then retrieve it during uninstall upon instantiation of the ServiceInstaller. This seems to have been naive, because it is not accessible during the install. If MyInstaller extends Installer, it can call base.Install(); however, my attempts to write to app.config (within MyInstaller.Install() and after base.Install()) are inneffective. So while the service can be installed with a custom Service Name, that name is not serialized and the installer is most displeased upon uninstall. How should this be done?

• Tiny MCE ImageManager Plugin, "cant create instance of plugin"

  - by Lofving

  We just bought MCImageManager and went right on to creating our own plugin. I followed http://wiki.moxiecode.com/index.php/MCI … ing_plugin from start to end but got stuck on the last step. After configuring the build.bat file (that comes along the package) it gives me no errors, i checked all paths and it should work but there just is no plugin.dll file anywhere to be found. (The bat file is also linked to the .net 1.4322, that should be changed by you at tinyMCE in my opinion) To circumvent that problem I started a new project and compiled the plugin.dll through Visual Studio. Then placed the dll in the c:..\project\plugins\plugin\bin\ folder (at the same place as the _TemplatePlugin.dll file but with the plugins name) All i get from running the application is "Could not create instance of plugin class: Moxiecode.Manager.Plugins.Plugin" What is it I'm missing? All the other plugins ain't giving this error and they follow the same structure as my custom plugin. Thanks in advance //Micael

• Dialing a command prefix on the iPhone

  - by tewha

  Our application lets users call phone numbers. Users would like to be able to block their caller ID. On other platforms, we let the user specify a custom dialing prefix. For instance, on my cell provider it's #31#. I've tried two approaches so far. First: id url = [NSURL URLWithString: @"tel:#31#0000000"] // produces nil Second: id encoder = ["#31#0000000" stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]; // produces %2331%230000000 id url = [NSURL URLWithString: [NSString stringWithFormat: @"tel:%@", encoded]]; // produces a valid-looking NSURL which doesn't do anything I'm thinking at this point that I'm just not allowed to dial # and *, even from a Cocoa touch application. (I know it's not allowed from a web app.) Is this true, or am I missing something obvious?

• SharePoint web part not displaying for site readers

  - by gregenslow

  Hello - I've built a custom SharePoint 2010 web part and deployed it to the home page of a publishing site. It's a very simple web part that just displays items from a SP list in a drop down list. The web part works fine if I'm logged in as a site owner or a member but not if I'm just a reader. The web part doesn't render at all to readers. I don't get any of the web part chrome or title, just nothing. I have other web parts (out-of-box ones) in the same zone that are displaying fine so it's not an issue of the whole zone not displaying. As a reader, I can still view the list directly so it doesn't appear to be a problem with list permissions. My web parts are being deployed as a farm solution, not sand-boxed and the assembly is being deployed to the GAC. I feel like I must be missing something simple here but I'm stumped. Help.

• C# Lambda Expression Speed

  - by Nathan

  I have not used many lambda expressions before and I ran into a case where I thought I could make slick use of one. I have a custom list of ~19,000 records and I need to find out if a record exists or not in the list so instead of writing a bunch of loops or using linq to go through the list I decided to try this: for (int i = MinX; i <= MaxX; ++i) { tempY = MinY; while (tempY <= MaxY) { bool exists = myList.Exists(item => item.XCoord == i && item.YCoord == tempY); ++tempY; } } Only problem is it take ~9 - 11 seconds to execute. Am I doing something wrong is this just a case of where I shouldn't be using an expression like this? Thanks.

• Adding relative path for an external graphic in a XSL document?

  - by Pran

  Hi, first of, I don't know much about XSL. I am using a app called DITA to generate pdfs. One of the things it requires is an overwrite of an xsl file; to add custom styling. I am trying to add an external graphic using a relative path. It doesn't work, unless I supply the full path. Does not work: <fo:block text-align="center" width="100%"> <fo:external-graphic src="../../images/logo.png"/> </fo:block> Does work: <fo:block text-align="center" width="100%"> <fo:external-graphic src="/absolute/path/to/images/logo.png"/> </fo:block> I looked on the web, it said to use "file:image.png" and other website said to use "url(image.png)", but neither worked. What am I doing wrong?

• What's the best way to paginate a dataset with Zend_Framework and Doctrine?

  - by joedevon

  Before I start to build this myself I thought I'd ask others to share their experience. What's the best / your favorite way to paginate a dataset with an application built upon Zend_Framework and Doctrine as your ORM? I'm new to Doctrine. I'm calling the model directly from a View Helper, bypassing the Controller, although I'm still interested if your solution uses controllers. I did see one article on this topic: http://ciaranmcnulty.com/blog/2009/06/Simplify-pagination-logic-using-a-custom-zend-paginator-adapter Devzone has an article using Doctrine, Zend Framework OR Pear, but none of those options mention a #ZF app that uses Doctrine.

• Using C# and VB.NET in one solution

  - by Younes

  I'm busy on a small project to convert an Access2003 db to .NET. I am trying to integrate my functionality in an excisting project that is being used for Administration of some kind. The code in this project is vb.net. I started by setting up my Data Access Layer, which seems to work fine. I can make new web pages that acces the data I need. However when i start to use class files to set up my Business Logic Layer i can't build my project when using C# instead of VB. I Dislike VB and like to program in C# as i know the syntax alot better etc. Is it possible to program using C# knowing that VB.NET was the language chosen to buold the entire project on? If not, what will be the smartest way to integrate my module into the project using my favorite programming language? (Make a project and reference to the dll?)

• how to keep dragged TitleWindow within Flex app boundary

  - by Tim

  I am using PopupManager in FB4 to display a custom dialog. popwin = new TitleWindow(); popwin.addElement(myCustomDialog); PopUpManager.addPopUp(popwin,this,false); PopUpManager.centerPopUp(popwin); It's possible to drag the popped up TitleWindow and let go of it when its gray title bar lies outside the bounds of the Flex app rectangle, and then the popup cannot be grabbed again. It's also possible to drag the TitleWindow downwards so it becomes completely invisible below the bottom edge of the Flex app rectangle. When the Flex app bounds are less than the full browser window, and the user is working quickly, this chances of this happening increase. Is there a simple setting that will keep this from happening, or must the programmer intercept the behavior during the drag operation? Thanks Tim

• No Flash, How do i handle jcupload ?

  - by acidzombie24

  I am using http://www.jcupload.com/ (basic) to upload files. I am considering having a friend write a more custom version or to do magic with ajax; so the solution should be able to work without that. With jcupload i include css, a script and write <div id="jcupload_content"></div> in my html and i am done. Problem is, with no flash i get an object box. Instead i would like is an iframe or a html form to upload the file. How do i do this? Should i detect flash from javascript and overload the div myself if no flash is available? How do i detect if flash is available? with jquery i know i can write something like $('#jcupload_content').innerHtml = blah; How do i handle the flash part?

• Flash CS4/AS3 Dynamic Text Box

  - by Jono

  Hi, I have created a XML image gallery, which displays text in between each slide. Now I have created a movie clip with a dynamic text field (with Render HTML selected) to display the text from the XML which is pushed into an array. Now, this all works great BUT... /n or /r is not creating a new line break (as they need to be custom). Yet if I create an Array and manually push strings "Bla bla bla /n bla bla bla" I get a line break. I have tried converting the Array item to string (even though it already is), I would also avoid creating textField = new textField() any Ideas would be welcomed. Cheers

• How to migrate project from RCS to CVS?

  - by Norman Ramsey

  I have a 20-year-old project that I would like to migrate from RCS to git, without losing the history. All web pages suggest that the One True Path is through CVS. But after an hour of Googling and trying different scripts, I have yet to find anything that successfully converts my RCS project tree to CVS. I'm hoping the good people at Stackoverflow will know what actually works, as opposed to what is claimed to work and doesn't. (I searched Stackoverflow using both the native SO search and a Google search, but if there's a helpful answer in the database, I missed it.) Things that don't work that I still remember: The rcs-to-cvs script that ships in the contrib directory of the CVS sources The rcs-fast-export tool at http://git.oblomov.eu/rcs-fast-export The rcs2cvs script found in a document called "CVS-RCS- HOW-TO Document for Linux"

• Equality and Assigment Operators

  - by Jeremy Smith

  I have a assembly compiled in VB.NET that contains two operators: Public Shared Operator =(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return quarterA.StartDate = quarterB.StartDate AndAlso quarterA.EndDate = quarterB.EndDate AndAlso quarterA.Quarter = quarterB.Quarter End Operator Public Shared Operator <>(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return Not (quarterA = quarterB) End Operator However, when using the assembly in C# to perform equality checks if (qtr != null) I receive the error: Cannot implicity convert type 'object' to 'bool' My original intent with the = operator was only for assignment purposes in VB, so I may be way off base (I don't use custom operators too often). What do I need to do to make the operator behave with both equality and assignment operations?

• Dynamic case statement in bash

  - by infra.user

  Hi folks, I'm trying to figure out how to create a dynamic case statement in a bash script. For example, let's say I have the output of an awk statement with the following contents red green blue In this scenario, the output can change at any time. I'm trying to then execute different logic if a value is included in this awk output. So if the data above is in $list, then I'd conceptually like to do something like: case "${my_var}" in $list) ..... something_else) ..... esac I'm trying to use this to build a dynamic custom tab completion function (see http://www.debian-administration.org/article/An_introduction_to_bash_completion_part_2 for some background). Any ideas? Thanks.

• ASP.NET GridView and UpdatePanel

  - by Echilon

  I have a GridView, inside a UserControl, inside an UpdatePanel on a page. There's a button in the GridView which needs to fire a postback. What happens is: User clicks button - RowCommand Fires - Custom event is raised on UserControl - Page detects this and changes the active view index for a multiview and also the page title and some other controls outside the UpdatePanel. The problem is, the page posts back asyncchronously, the page title changes, but the actions requireing a full postback don't happen because a full postback doesn't occur. To register the button as a postback trigger I'm using: ImageButton btnResults = e.Row.FindControl("btnResults") as ImageButton; ScriptManager scrCurrent = ScriptManager.GetCurrent(this.Page); if (btnResults != null && scrCurrent != null) { scrCurrent.RegisterPostBackControl(btnResults); } I know this is a bit of a complicated problem, but I'd really appreciate any help.

• Three20 - add items to launcherView after viewDidLoad

  - by lostInTransit

  Hi I am getting a list of image URLs and corresponding names at run time in my app. I would like to add these images to a TTLauncherView object that I have. Cannot add these in loadView. I am making a call to the method for getting my data in a separate thread. Once the thread completes, I add the TTLauncherItem objects to an array and set the "pages" variable of the LauncherView. But for some reason, the view is not updated and I don't see anything on it. Can someone please let me know how to refresh the launcherview after adding items to it in methods other than loadView? Thanks.
