• scanned image in C#

  - by ahmed fouad

  We wanna a c# solution to correct the scanned image becouse it is rotated and to solve this problem we must detect the rotation angle first then rotate the image.this was our first thinking for our problem then we think image warping will be more accurate as i think it will make the scanned image like our template so we can process it as we know all the coordinates of our template ....... i search for a free SDK or a free solution in c# and helping me in this will be graet work as it is the last task in our working. rally thanxxxx for all.

• LINQ to SQL repository - caching data

  - by creativeincode

  I have built my first MVC solution and used the repository pattern for retrieving/inserting/updating my database. I am now in the process of refactoring and I've noticed that a lot of (in fact all) the methods within my repository are hitting the database everytime. This seems overkill and what I'd ideally like is to do is 'cache' the main data object e.g. 'GetAllAdverts' from the database and to then query against this cached object for things like 'FindAdvert(id), AddAdvert(), DeleteAdvert() etc..' I'd also need to consider updating/deleting/adding records to this cache object and the database. What is the best apporoach for something like this? My knowledge of this type of things is minimal and really looking for advice/guidance/tutorial to point me in the right direction. Thanks in advance.

• Problem making ant compile my classes present in different Eclipse projects into single destination

  - by KCore

  I have close to about 20 projects in my Eclipse workspace. They are interdependent. Now I want to build all of them in a single war file. The thing is eclipse does it nicely... if I create a Dynamic Web Project and link sources of all the 20 projects. But I want to automate the entire process and want to be able to run a script (ant maybe..) and deploy a war in my app server. My approach: I started with a simple approach. I tried to sequentially build each project (javac task) with destination directory as web-inf of my war. But it is giving me weird errors like : package " ** " not found,when it shows the same all the required classes in classpath (I used verbose) Do you think, a continous integration engine will be better for my case (20 projects..) I saw Team City, but didnt get it the first time...

• Writing a search engine

  - by wvd

  Hello all, The title might be a bit misleading, but I couldn't figure out a better title. I'm writing a simple search engine which will search on several sites for the specific domain. To be concrete: I'm writing a search engine for hardstyle livesets/aftermovies/tracks. To do I will search on the sites who provide livesets, tracks, and such. The problem here is speed, I need to pass the search query to 5-7 sites, get the results and then use my own algorithm to display the results in a sorted order. I could just "multithread" it, but it's easier said then done so I have a few questions. What would be the best solution to this problem? Should I just multithread/process this application, so I'm going to get a bit of speed-up? Are there any other solutions or I am doing something really wrong? Thanks, William van Doorn

• 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?

• 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.

• 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!

• 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.

• 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!

• 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?

• 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?

• 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.

• 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

• 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

• 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.

• C# SqlDataAdapter not populating DataSet

  - by Wesley

  I have searched the net and searched the net only to not quite find the probably I am running into. I am currently having an issue getting a SqlDataAdapter to populate a DataSet. I am running Visual Studio 2008 and the query is being sent to a local instance of SqlServer 2008. If I run the query itself in SqlServer, I do get information. Code is as follows: string theQuery = "select Password from Employees where employee_ID = '@EmplID'"; SqlDataAdapter theDataAdapter = new SqlDataAdapter(); theDataAdapter.SelectCommand = new SqlCommand(theQuery, conn); theDataAdapter.SelectCommand.Parameters.Add("@EmplID", SqlDbType.VarChar).Value = "EmployeeName"; theDataAdapter.Fill(theSet); The code to read the dataset: foreach (DataRow theRow in theSet.Tables[0].Rows) { //process row info } If there is any more info I can supply please let me know.

• See if any application has a DLL from the GAC loaded

  - by rwmnau

  I'm trying to deploy new copies of my DLL to the GAC on remote servers, but I need to identify if any processes currently running have a loaded copy of the DLL I'm replacing - I'd like to restart them, or at least tell the user. For example, Biztalk seems to load the DLLs it needs the first time they're used, and then replacing them keeps the old copy in memory until the Host Instances are restarted - something I could easily do as part of my deployment. Is there a way to tell using .NET which processes have loaded a particular DLL from the GAC? UPDATE: Some further investigation shows that both Process Explorer has this functionality, and another Sysinternals tool, ListDLL, does exactly what I want to be able to do. I'd like to know how they do it, since I'd love to replicate this functionality in my application without having to include and screen-scrape ListDLL (if that's even allowed inside the license).

• Pipeline For Downloading and Processing Files In Unix/Linux Environment With Perl

  - by neversaint

  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?

• 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?

• 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?
