• Updating Lucene index from two different threads in a web application

  - by Jimmy

  Hi, I've a .net web application which uses Lucene.net for company search functionality. When registered users add a new company,it is saved to database and also gets indexed in Lucene based company search index in real time. When adding company in Lucene index, how do I handle use case of two or more logged-in users posting a new company at the same time?Also, will both these companies get indexed without any file lock, lock time out, etc. related issues? Would appreciate if i could help with code as well. Thanks.

• Javascript: Looking for a script that will allow me to scroll content sideways

  - by lewisqic

  Hi All, I'm trying to find some javascript code that I can embed on my website that will allow me to scroll content from left to right or right to left. This script here: http://www.dynamicdrive.com/dynamicindex11/scrollc2.htm Has the basic functionality that I am looking for, but it scrolls content from top to bottom. I want to be able to scroll my content sideways and have it scroll when I hover over some arrows just like the above mentioned script does. Does anyone know of anything that will work for me? Or perhaps it would be simple to modify the above mentioned script to scroll side to side. Thanks.

• Is this the correct way of speaking to a "Content Manager" Class?

  - by DeanMc

  I am creating a silverlight site. I am currently breaking out my ideas into pieces of functionality. One of the idea's I have is the concept of a content manager. This is essentially a UI control with 4 regions. Top, Bottom, Right & Left. I also have a collection of objects that are considered "Menu Items". These are controls that function as a way to navigate around, similar to links. The idea I have is to implement an IMenuItem interface. Among the standard pieces of information (Text, PageReference, etc) I was also going to hold a reference to the content manager. My idea behind this thinking is that I can pass the PageReference to a property on the ContentManager and then call a method which knows how to update the content manager accordingly. Is this the best way of implementing this or is their some sort of pattern for it?

• How to specify behavior of Java BufferedImage resize: need min for pixel rows instead of averaging

  - by tucuxi

  I would like to resize a Java BufferedImage, making it smaller vertically but without using any type of averaging, so that if a pixel-row is "blank" (white) in the source image, there will be a white pixel-row in the corresponding position of the destination image: the "min" operation. The default algorithms (specified in getScaledInstance) do not allow me a fine-grained enough control. I would like to implement the following logic: for each pixel row in the w-pixels wide destination image, d = pixel[w] find the corresponding j pixel rows of the source image, s[][] = pixel[j][w] write the new line of pixels, so that d[i] = min(s[j][i]) over all j, i I have been reading on RescaleOp, but have not figured out how to implement this functionality -- it is admittedly a weird type of scaling. Can anyone provide me pointers on how to do this? In the worse case, I figure I can just reserve the destination ImageBuffer and copy the pixels following the pseudocode, but I was wondering if there is better way.

• iPhone SDK Smaller CAF files: lower recording quality with Audio Queues?

  - by Nick

  In my iPhone app I have voice recording functionality the utilizes Audio Queue voice recording functions of the SDK. I'm saving directly to CAF format and using the following settings for the AudioStreamBasicDescription reference: audioFormat.mFormatID = kAudioFormatLinearPCM; I can see that there are other format ids I could use like: kAudioFormatLinearPCM kAudioFormatAppleLossless kAudioFormatAppleIMA4 kAudioFormatiLBC kAudioFormatULaw kAudioFormatALaw My knowledge of sound formats is very limited so my question is... which of these should I use to create the lowest compressed audio recording files? Plus, are there other settings I should apply to lower the quality and filesize even further?

• Using a C#.net DLL in Node.js / serverside javascript

  - by Dve

  I have spent a while playing with node.js and exploring related frameworks such as express and geddy... and I am very impressed, especially with the WebSockets implementation in socket.io. I have a pet project that is an online game, the entire game engine is written in C# and I would like to know if there is anyway I can call the functions of this existing dll from a solution built using node.js, socket.io, express etc? The game engine itself is pretty complete; tested and robust. I am hoping there is some neat way of exposing its functionality without to much overhead. Thanks

• Jquery UI Slider - Input a Value and Slider Move to Location

  - by RobertC

  I was wondering if anyone has found a solution or example to actually populating the input box of a slider and having it slide to the appropriate position onBlur() .. Currently, as we all know, it just updates this value with the position you are at. So in some regards, I am trying to reverse the functionality of this amazing slider. One link I found: http://www.webdeveloper.com/forum/archive/index.php/t-177578.html is a bit outdated, but looks like they made an attempt. However, the links to the results do not exist. I am hoping that there may be a solution out there. I know Filament has re-engineered the slider to handle select (drop down) values, and it works flawlessly.. So the goal would be to do the same, but with an input text box. Any help would be incredible! Thanks in Advance!! Robert

• WCF Service Error

  - by Sanjeev K B

  Hi, I have a WCF service deployed on a windows 2003 server. We are using a WPF application to consume this service. The trouble is if we deploy a new version of WCF service or leave the IIS and WPF application idle for sometime and then try to execute a functionality, we are get the following exception: The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 119 bytes of the response were:'<HEAD><TITLE>500: Server Error [20-0004]</TITLE></HEAD> <BODY> <H1>500: Server Error [20-0004]<H1> </BODY> </HTML> Thanks and Regards,

• Edite, select value from UITableView on the iPhone

  - by Anthony D

  I have a UITableView with a list of names, representing server configurations. I want the user to be able to select a server configuration, add a server config, edit a server config, or just cancel out of the view and return to the main view. I'm having a hard time trying to figure out how to achieve all of that functionality in this view. To select, the user should be able to just tap the server config name and a check will appear next to the name then the user is taken back to the main view automatically (or use a save button instead?). To edit the server config, I would also like the user to be able to tap the server config name and be taken to a detail screen where changes can be made. How can I accomplish both since I want both to be done by tapping the server name (row)? Right now the cancel button seems out of place since the screen is accessed via a UINavigationController. Any suggestions?

• Start Android intent from email

  - by AndersWid

  Hi! I need a good way of sending information TO the Android device that doesn't use a special server that has XML data. I would like to base this around email functionality. Lets say I send an email with some special text/link that when clicked starts and intent on the phone. I don't want to replace the users current email application. A clickable link would be the best thing "intent://data1:data2" or something along these lines. Speculations/solutions on how to proceed.

• How do you include additional files using VS2010 web deployment packages?

  - by Jason

  I am testing out using the new web packaging functionality in visual studio 2010 and came across a situation where I use a pre-build event to copy required .dll's into my bin folder that my app relies on for API calls. They cannot be included as a reference since they are not COM dlls that can be used with interop. When I build my deployment package those files are excluded when I choose the option to only include the files required to run the app. Is there a way to configure the deployment settings to include these files? I have had no luck finding any good documentation on this.

• What is a good Java crawler library?

  - by DrDee

  Hi, I am about to develop a crawler in Java but don't feel like reinventing the wheel. A quick Google search gives a whole bunch of Java libraries to build a web crawler. Besides that Nutch is of course a very robust package but seems a bit too advanced for my needs. I only need to crawl a handful websites a week containing a couple of 1000 pages each. Which open source Java library would you recommend considering: speed multithreading (or even distributed) extending it with new functionality active maintained and documentation?

• Cfsearch in combination of documents and indexed query data?

  - by Bart B

  hi! I have an application which stores all kind of data about people. The current cfsearch functionality (in Verity) includes searching documents that are attached to these people. If i have 2 documents attached to 1 person, 1 with say ABC in it and the other with XYZ in it, my ideal searchresult for "ABC AND XYZ" would return the 1 person. But as both 'words' are indexed in different documents, the standard behaviour is not to return any result from the cfsearch, because the combination doesnt exist in any of the 2 documents. Is there any way to combine indexed documents and/or query data in a way that the search is executed in the combination of relevant docs and data? In my application that would mean that i could index all documents and data regarding people and have an intelligent 'global' search to find the right person. any pointers and help very much appreciated! (should Solr offer new possibilities in comparison to Verity, no problem!) thanks! Bart

• Windows Workflow and sql script in declarative config like InRule

  - by Satish

  We have been using InRule for our Rule needs we have found that it does not scale well and so are investigating the Windows Work Flow. Within InRule we could configure pretty much have any task for example our sql scripts and stored procedures where all part of a separate rule config file, I am wondering if there is a similar functionality within windows work flow where I could just call a declarative task and pass it a bunch of parameters – This task should contain the sql script I would be executing , we should be able to change the script at runtime without recompilation to the WF code. Is this possible in Windows Work flow – How can I accomplish this within work flow. Additionally for sql execution within Work Flow, how does it get the connection string. Should it be passed from the calling program – is passing it as input parameter from the Calling app via the Dictionary object the best way or can the work flow code have visibility to my calling program app.config and get the connection string ?

• Django URL resolving infrastructure stops working

  - by btol45

  We recently launched a new Django-powered website, and we are experiencing the oddest bug: The site is running under Apache with mod_fastcgi. Everything works fine for a while, and then the URL tag and reverse() functionality stops working. Instead of returning the expected URL, they return "". We haven't noticed anything in Apache's log file; there are no errors being generated by Django. And (the kicker) the problem only occurs in production mode; we can't reproduce it when DEBUG=True. Any thoughts on where we should be looking for the problem?

• jquery select item in radiobuttonlist via client-side function

  - by mcliedtk

  I have the following ASP.NET RadioButtonList: <asp:RadioButtonList ID="rbl" runat="server"> <asp:ListItem Text="Type1" Value="1" /> <asp:ListItem Text="Type2" Value="2" /> </asp:RadioButtonList> I would like to select an item in the list programmatically via a client-side jquery function like this (simplified version): function BindWidget(widget) { // Type property of Widget is an int. $("#<%=rbl.ClientID%>").selectItemByValue(widget.Type); } Ideally, there is some function - in the above code I have proposed selectItemByValue - that selects an item in a RadioButtonList by a given value. Does jquery have a similar function built-in? If not, how should I go about implementing the desired functionality?

• Org-mode anniversary property to agenda

  - by lecodesportif

  I am trying to have the "Birthday" property of an Org-mode contact entry added to the agenda automatically: * John :PROPERTIES: :Name: John :Birthday: 5 4 1900 :END: This can be done manually for each entry using: %%(diary-anniversary 5 4 1900) John's birthday But I don't want to type the date twice. I would like to use the org-entry-get functionality to make diary-anniversary take the values of the Birthday and Name (see the bold text above) properties. This is how I get the correct property values. %%(org-entry-get nil "Name") %%(org-entry-get nil "Birthday") But after several attempts, I still haven't managed to put the values in variables and pass them correctly to diary-anniversary. Any ideas how to do it?

• Silverlight TabItem template not working correctly

  - by Savvas Sopiadis

  Hello everybody! In a SL4 application i need to restyle my TabItems (actually add a button in the header). So i took the TabItem's control template from here and added the functionality i wanted. This seems to work fine, (i could dynamically add tabitems) with one exception: i think this posted control template is behaving somehow "arbitrary": every time the mouse hoovers over a non selected TabItem header, this gets selected WHITHOUT clicking!! (afaik this is not the default behavior: the user user has to click a header to make this tabitem the selected one). I tried to find why it is behaving like this, with no luck! Is there someone who can enlighten my darkness??? Thanks in advance!

• Getting values from Multiple Text Entry using Pygtk and Python

  - by Webrsk

  On a click of a button named "Add Textbox" it calls a function which creates a single textbox using (gtk.Entry) function. So each time i click that button it creates a textbox. I have a submit button which should fetches all the values of the text boxes(say 10 textboxes) generated with the name of "entry". It works for one textbox but not for multiple. In php we can create dynamix textboxes mentioning as an array name=entry[]. Do we have similar functionality in python ? Enviroment : FC10 , Glade 3 , Python 2.5 , GTK.

• Breaking changes in .NET 4.0

  - by Andrei Taptunov

  There is a lot of information about new features and classes in new 4.0 however there are also changes that may affect esixting applications, for example Timespan now implements IFormattable and old string.Format() with invalid options will throw exception instead of calling simple ToString(). However, CLR team provides a nice feature to enable behaviour from previous version with configuration setting - TimeSpan_LegacyFormatMode . CLR Inside Out Access to events inside the class where they are declared using += or -= will lead to call add/remove generated accessors that return void. Some code wan't even compile in 4.0. Chris Burrows Blog CAS is deprecated and to enable it one still need to use special setting in configuration - NetFx40_LegacySecurityPolicy So I wonder what are other changes and is it possible to find at least preliminary list of changes that will or may break existing functionality with release of .NET 4.0 ?

• Is .NET support for Win32 Code Interop?

  - by Usman

  Hello, I need to InterOp Win32 code (unmanaged Win32 DLL's and Exe) completely with .NET. I need to call Win32 unmanaged code(DLL exported functions) at runtime i.e (knowing the types of data types in Win32 signatures and need to pass data according to that type at runtime). This is 100% possible in case of COM. You can convert COM unmanaged code to managed assemblies using tlbimp.exe and use now reflection API to work with those managed types(actual were unmanaged types now converted managed using tlbimp). But same functionality I need to get in terms of Win32(i.e) in .NET framework. How?? I know MS provided Export table reading API ..but I couldn't find exact API for InterOp of Win32 unmanaged code Regards

• asp.net mvc: handling no-javascript

  - by Bala R

  Hello, I'm working on a asp.net mvc2 app. I have been using jquery to do various different things in all of my views. They are work from a regular browser quite well. But I'm trying to figure out a good way to get the functionality working with browsers with javascript disabled (like mobile browsers). Is there a way to define a whole different view for non javascript browsers? A specific example of what I'm trying to do is, I have a with it's onClick calling a javascript that does $.post() to a controller. What's a good way to make it, so, it works the way it works right now (doing ajax calls) with regular javascript-enabled browsers and it a also works with javascript-incapable browsers, doing a full postback ? Thanks
