• How do I get the ID or reference of the listview row I am clicking a checkbox in?

  - by danielea

  I have an ASP.NET 2.0 ListView control (aka:parent) and configured inside this ListView I have another ListView (aka:child). For each row the parent has there is potentially a child ListView control which can have 1-3 rows. Each row has two checkboxes (a select checkbox and a deny checkbox). I need to process these checkboxes in JavaScript so that if one select is chosen on any of the rows all other select checkboxes are unchecked AND the deny checkbox for that row only is unchecked. The rows which were NOT selected CAN have the deny checkboxes checked. What is the best approach to this?

• Different Versions of an application in same java application server

  - by Cem

  Hi, We are utilizing citrix netscalar with more than 20 glassfish java application servers. Unfortunately we have to remove previous application before deploying a new version of it since we have same context for these two different application. This error-prone process leads some problems due to lack of attention in builds or other problems. In an urgent case, we simply want to redirect to all traffic to previous application. What is the best practice to run different version of an application in a substantial number of servers in same time? Thanks

• MVC3 Razor DropDownListFor Enums

  - by jordan.baucke

  Trying to get my project updated to MVC3, something I just can't find: I have a simple datatype of ENUMS: public enum States() { AL,AK,AZ,...WY } Which I want to use as a DropDown/SelectList in my view of a model that contains this datatype: public class FormModel() { public States State {get; set;} } Pretty straight forward: when I go to use the auto-generate view for this partial class, it ignores this type. I need a simple select list that sets the value of the enum as the selected item when I hit submit and process via my AJAX - JSON POST Method. And than the view (???!): <div class="editor-field"> @Html.DropDownListFor(model => model.State, model => model.States) </div> thanks in advance for the advice!

• Design Patterns: What's the antithesis of Front Controller?

  - by Brian Lacy

  I'm familiar with the Front Controller pattern, in which all events/requests are processed through a single centralized controller. But what would you call it when you wish to keep the various parts of an application separate at the presentation layer as well? My first thought was "Facade" but it turns out that's something entirely different. In my particular case, I'm converting an application from a sprawling procedural mess to a clean MVC architecture, but it's a long-term process -- we need to keep things separated as much as possible to facilitate a slow integration with the rest of the system. Our application is web-based, built in PHP, so for instance, we have an "index.php" and an IndexController, a "account.php" and an AccountController, a "dashboard.php" and DashboardController, and so on.

• Adding file of the same name into the same list and unable to update name of the SPFile

  - by BeraCim

  Hi all: I'm having difficulties adding file of the same name in the same list and subsequently updating/changing/modifying the name of a SPFile. Basically, this is what I'm trying to do: string fileName = "something"; // obtained from a loop -- loop omitted here. SPFile file = folder.Files.Add(fileName, otherFile.OpenBinary()); The Add method will generate a runtime exception when it finds another file of the same name in the same list/folder. So I thought of changing the file name later in the process: string newGuid = Guid.NewGuid().ToString(); SPFile file = folder.Files.Add(newGuid, otherFile.OpenBinary()); // some other processing... afterwards, rename the file file.name = fileName; file.Item.Update(); A few minute of googling indicated I need to either move the file around, or update the name field by using ["Name"] instead. I was wondering are there any other better ways to get around this problem? Thanks.

• Script or automate feature class creation in ESRI/ArcSDE

  - by Keith G

  I'm looking for info on how to write SQL scripts to automate the creation of a versioned feature class in ArcSDE I want to be able to automate the process itself as well as put the scripts under version control. Can anyone point me to a resource that explains how to do this? Is this even possible? It seems like there are lots of interrelationships between tables and data when a feature class is added. P.S. It doesn't have to be pure SQL, but it should be some kind of scripting so we can save to version control and run outside of ESRI desktop tools.

• Monolog conversations in SQL Service Broker 2008

  - by hemil

  Hi, I have a scenario in which I need to process(in SQL Server) messages being delivered as .xml files in a folder in real time. I started investigating SQL Service Broker for my queuing needs. Basically, I want the Service Broker to pick up my .xml files and place them in a queue as they arrive in the folder. But, SQL Service Broker does not support "Monolog" conversations, at least not in the current version. It supports only a dialog between an initiator and a target service. I can use MSMQ but then I will have two things to maintain - the .Net Code for file processing in MSMQ and the SQL Server T-SQL stored procs. What options do I have left? Thanks.

• Create a SOCKS Proxy that does nothing special

  - by rwired

  I am trying to create a SOCKS proxy in C++ that runs as a background process on localhost. If the user's browser is configured to use the proxy, I want all HTTP requests to be passed along through the normal TCP/IP stack. i.e. The browser will behave exactly as it normally would. Eventually I will add another layer which will check to see if the requested resource matches certain criteria, and if so will handle the request differently. But for now I'm just trying to solve the basic problem... how to create a SOCKS proxy that doesn't change anything?

  - by silverkid

  which is the best tool for this - Automation of signup process to a website , e.g an email signup The tool should be able to take data from an external data file like an excel of csv file this data file would contain data such as first name , last name , username, password etc. basic data required during an email signup . I am imagining the data file to contain of each field in a seperate column and each row to contain data for different registration / user. At the places where manual intervention is required like image verification etc. the tool should be able to pause the script until manual bit is done then continue with the script. What is the best way to do this - an automation tool , or any scripting language - please suggest .

• RenderAction in an HtmlHelperExtension Method?

  - by TimLeung

  I am trying to call the RenderAction Extension Method within my own Html Helper: System.Web.Mvc.Html.ChildActionExtensions.RenderAction(helper, "account", "login"); this is so that along with some additional logic, I would like all html helpers to use a common method name structure when calling it on the view: <%= Html.CompanyName().RenderAccount() %> but the problem I am having is that, asp.net will complain about not finding the actual route it needs to process. It does not take in the parameters of "controller" to be used as the action and "login" to be used as the action. It seems to only reference the current route. Any ideas how I can package up the RenderAction?

• In-memory Database in Excel

  - by user329174

  Hello, I am looking for a way to import a datatable from Access into an Excel variable and then run queries through this variable to speed up the process. I am trying to migrate from C# .NET where I read a data table from an access database into memory and then used LINQ to query this dataset. It is MUCH faster than how I have it currently coded in VBA where I must make lots of calls to the actual database, which is slow. I have seen the QueryTable mentioned, but it appears that this requires pasting the data into the excel sheet. I would like to keep everything in memory and minimize the interaction between the Excel Sheet and the VBA code as much as possible. I wish we didn't need to use Excel+VBA to do this, but we're kind of stuck with that for now. Thanks for the help!

• Missing artifact error in Maven

  - by abhin4v

  I get a missing artifact error during Maven build because one of the dependencies declares it's parent artifact using a property for the version. Now the property itself is declared in the parent pom and my project's build fails giving this error: [ERROR] Failed to execute goal on project abc: Unable to get dependency information for xyz:pqr:jar:SNAPSHOT: Failed to process POM for xyz:pqr:jar:SNAPSHOT: Non-resolvable parent POM xyz:pqr-parent:${someversion} for xyz:pqr:${someversion}: Failed to resolve POM for xyz:pqr-parent:${someversion} due to Missing: ---------- 1) xyz:pqr-parent:pom:${someversion} ---------- 1 required artifact is missing. for artifact: xyz:pqr-parent:pom:${someversion} I have verified that the artifacts are present in correct location in the repository. Is there a way to specify the value of someversion property used in the dependency pom? If not, how should the dependency pom be changed to resolve the error?

• How should I handle incomplete packet buffers?

  - by Benjamin Manns

  I am writing a client for a server that typically sends data as strings in 500 or less bytes. However, the data will occasionally exceed that, and a single set of data could contain 200,000 bytes, for all the client knows (on initialization or significant events). However, I would like to not have to have each client running with a 50 MB socket buffer (if it's even possible). Each set of data is delimited by a null \0 character. What kind of structure should I look at for storing partially sent data sets? For example, the server may send ABCDEFGHIJKLMNOPQRSTUV\0WXYZ\0123!\0. I would want to process ABCDEFGHIJKLMNOPQRSTUV, WXYZ, and 123! independently. Also, the server could send ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890LOL123HAHATHISISREALLYLONG without the terminating character. I would want that data set stored somewhere for later appending and processing. Also, I'm using asynchronous socket methods (BeginSend, EndSend, BeginReceive, EndReceive) if that matters.

• how do i claim a low-numbered port as non-root the "right way"

  - by qbxk

  I have a script that I want to run as a daemon listening on a low-numbered port (< 1024) Script is in python, though answers in perl are also acceptable. The script is being daemonized using start-stop-daemon in a startup script, which may complicate the answer What I really (think) don't want is to type ps -few and see this process running with a "root" on it's line. How do I do it? ( from my less-than-fully-educated-about-system-calls perspective, I can see 3 avenues, Run the script as root (no --user/--group/--chuid to start-stop-daemon), and have it de-escalate it's user after it claims the port Setuid root on the script (chmod u+s), and run the script as the running user, (via --user/--group/--chuid to start-stop-daemon, the startup script still has to be called as root), in the script, acquire root privileges, claim the port, and then revert back to normal user something else i'm unaware of )

• 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

• handle user logoff or machine shutdown requests on WindowsME

  - by skylap

  I have to write a C# application that runs on WindowsME. Yes, I mean that Microsoft operating system that has been forgotten a long long time ago. My program needs no user interaction and as WindowsME doesn't support services, it will be a console application. Furthermore it will be used on more modern operating systems, where the user can choose whether to start it as console application or install it as a windows service. Now suppose the software is running on WinME and the user decides to logoff or shutdown the machine without a prior quit of my software. WinME complains about my program still running and asks if it should kill the process. Apart from the bad user experiance, this means that the application is not shut down properly. So I look for a way to be informed if the user logs off or wants to shutdown the machine to be able to perform a proper shutdown of my software first.

• TestCase scripting framework

  - by Mikey

  Hey guys, For our webapp testing environment we're currently using watin with a bunch of unit tests, and we're looking to move to selenium and use more frameworks. We're currently looking at Selenium2 + Gallio + Xunit.net, However one of the things we're really looking to get around is compiled testcases. Ideally we want testcases that can be edited in VS with intellisense, but don't require re-compilling the assembly every single time we make a small change, Are there any frameworks likely to help with this issue? Are there any nice UI tools to help manage massive ammount of testcases? Ideally we want the testcase writing process to be simple so that more testers can aid in writing them. cheers

• 0xDEADBEEF equivalent for 64-bit development?

  - by Peter Mortensen

  For C++ development for 32-bit systems (be it Linux, Mac OS or Windows, PowerPC or x86) I have initialised pointers that would otherwise be undefined (e.g. they can not immediately get a proper value) like so: int *pInt = reinterpret_cast<int *>(0xDEADBEEF); (To save typing and being DRY the right-hand side would normally be in a constant, e.g. BAD_PTR.) If pInt is dereferenced before it gets a proper value then it will crash immediately on most systems (instead of crashing much later when some memory is overwritten or going into a very long loop). Of course the behavior is dependent on the underlying hardware (getting a 4 byte integer from the odd address 0xDEADBEEF from a user process may be perfectly valid), but the crashing has been 100% reliable for all the systems I have developed for so far (Mac OS 68xxx, Mac OS PowerPC, Linux Redhat Pentium, Windows GUI Pentium, Windows console Pentium). For instance on PowerPC it is illegal (bus fault) to fetch a 4 byte integer from an odd address. What is a good value for this on 64-bit systems?

  I have a list of files URLS where I want to download them: http://somedomain.com/foo1.gz http://somedomain.com/foo2.gz http://somedomain.com/foo3.gz What I want to do is the following for each file: Download foo1,2.. in parallel with wget and nohup. Every time it complete download process them with myscript.sh What I have is this: #! /usr/bin/perl @files = glob("foo*.gz"); foreach $file (@files) { my $downurls = "http://somedomain.com/".$file; system("nohup wget $file &"); system("./myscript.sh $file >> output.txt"); } The problem is that I can't tell the above pipeline when does the file finish downloading. So now it myscript.sh doesn't get executed properly. What's the right way to achieve this?

• ado.net slow updating large tables

  - by brett

  The problem: 100,000+ name & address records in an access table (2003). Need to iterate through the table & update detail with the output from a 3rd party dll. I currently use ado, and it works at an acceptable speed (less than 5 minutes on a network share). We will soon need to update to access 2007 and its 'non jet' accdb format to maintain compatability with clients. I've tried using ado.net datsets, but updating the records takes hours! We process 5-10 of these tables per day - so this cannot be a solution. Any ideas on the fastest way to update individual records using ado.net? Surely we didn't take such a hugh backward step with ado.net? Any help would be appreciated.

• Easily switching ConnectionStrings on publish to Azure

  - by David Pfeffer

  I'm currently building an Azure Web Role. I am testing this project against a local database server on localhost. Then, when confident that the project is working, I publish it to Staging on Windows Azure. However, I also have to remember to change the connection string to point to the live SQL server on SQL Azure before deploying, and then change it back to localhost afterwards. Is there any nice way to automate this, or perhaps a different process to take to avoid the issue altogether? For example is there a way to have a configuration file for Azure that isn't updated with every deploy?
