  • Which is the best .NET image capture API for me to use?

    - by David
    I have been tasked with integrating image acquisition into a .NET application and I have been looking for an API to use for performing this function. I have come across several "standard" APIs, some have been in existence for a long time, some not so long. I have looked at references to ISIS, TWAIN, WIA, and SANE (said to be mostly *nix). They all appear to be Win32 libraries except for SANE, and I was wondering what the current recommendations are for talking to image acquisition devices (scanners)? Feel free to recommend something else if you feel it is better. I'm looking for open source options. Edit: I put open source, when what I actually meant was free. using WIA or TWAIN is fine since they are free even though they are proprietary interfaces.

  • Are JSF 2.x ViewScoped Beans Thread Safe?

    - by Mark
    I've been googling for a couple hours on this issue to no eval. WELD docs and the CDI spec are pretty clear regarding thread safety of the scopes provided. For example: Application Scope - not safe Session Scope - not safe Request Scope - safe, always bound to a single thread Conversation Scope - safe (due to the WELD proxy serializing access from multiple request threads) I can't find anything on the View Scope defined by JSF 2.x. It is in roughly the same bucket as the Conversation Scope in that it is very possible for multiple requests to hit the scope concurrently despite it being bound to a single view / user. What I don't know is if the JSF implementation serializes access to the bean from multiple requests. Anyone have knowledge of the spec or of the Morraja/MyFaces implementations that could clear this up?

  • How do I share a Hibernate SessionFactory across web applications?

    - by Jer
    I have two web applications that are running on a single Tomcat server and are connected to the same database with Hibernate. I am concerned that having two SessionFactory instances running around might cause some issues. Also, since both web applications share much of the same application logic, I thought it would be a good idea to centralize as much as I could. And since I use Spring for DI and Hibernate configuration it would make sense to have a single ApplicationContext as well. How would I go about doing something like this? Do I need to deploy a headless WAR that creates an ApplicationContext and thus a SessionFactory and allow each application access to it? Is this even a good idea?

  • How to create an aspect on class, that is not a bean using Spring AOP?

    - by Ula Krukar
    Hello, I work on an legacy application, where Spring AOP (namely ProxyFactoryBean) is used. I need to add an aspect around a method of a certain class. This class is not a bean however. The AspecjJ pointcut expression would be like this: execution(* xyz.package.Class.method()) I created a MethodInterceptor and AspectJExpressionPointcut, but I don't know how make those two work together. EDIT: I do not have source code for this class, it is a 3rd party library. The instances of this class are not created by me, neither in source code, nor in spring configuration as beans. It is used internally by the library. Any help appreciated.

  • Parameterized SQL statements vs. very simple method

    - by Philipp G
    When I started to write the first SQL-Statements in my programs I felt quite comfortable with protecting myself against SQL-Injection with a very simple method that a colleague showed me. It replaced all single quotes with two single quotes. So for example there is a searchfield in which you can enter a customername to search in the customertable. If you would enter Peter's Barbershop The SELECT Statement would look like SELECT * FROM Customers WHERE Customername = 'Peter''s Barbershop' If now an attacker would insert this: ';DROP TABLE FOO; -- The statement would look like: SELECT * FROM Customers WHERE Customername = ''';DROP TABLE FOO;--' It would not drop any table, but search the customertable for the customername ';DROP TABLE FOO;-- which, I suppose, won't be found ;-) Now after a while of writing statements and protecting myself against SQL-Injection with this method, I read that many developers use parameterized statements, but I never read an article where "our" method was used. So definitely there is a good reason for it. What scenarios would parameterized statements cover but our method doesn't? What are the advantages of parameterized statements compared to our method? Thanks Philipp

  • using macro defined in header files

    - by Neeraj
    I have a macro definition in header file like this: // header.h ARRAY_SZ(a) = ((int) sizeof(a)/sizeof(a[0])); This is defined in some header file, which includes some more header files. Now, i need to use this macro in some source file that has no other reason to include header.h or any other header files included in header.h, so should i redefine the macro in my source file or simply include the header file header.h. Will the latter approach affect the code size/compile time (I think yes), or runtime (i think no)? Your advice on this!

  • C# -Interview Question Anonymous Type

    - by Amutha
    Recently i was asked to prove the power of C# 3.0 in a single line( might be tricky) i wrote new int[] { 1, 2, 3 }.Union(new int[]{10,23,45}). ToList().ForEach(x => Console.WriteLine(x)); and explained you can have (i) anonymous array (ii) extension method (iii)lambda and closure all in a single line.I got spot offer. But..... The interviewer asked me how will you convert an anonymous type into know type :( I am 100% sure ,we can not do that.The interviewer replied there is 200% chance to do that if you have a small work around.I was clueless. As usual,I am waiting for your valuable reply(Is it possible?).

  • Sum of path products in DAG

    - by Jules
    Suppose we have a DAG with edges labeled with numbers. Define the value of a path as the product of the labels. For each (source,sink)-pair I want to find the sum of the values of all the paths from source to sink. You can do this in polynomial time with dynamic programming, but there are still some choices that can be made in how you decompose the problem. In my case I have one DAG that has to be evaluated repeatedly with different labelings. My question is: for a given DAG, how can we pre-compute a good strategy for computing these values for different labelings repeatedly. It would be nice if there was an algorithm that finds an optimal way, for example a way that minimizes the number of multiplications. But perhaps this is too much to ask, I would be very happy with an algorithm that just gives a good decomposition.

  • Problems with FileSet in Ant script?

    - by ipkiss
    Hi, I am using Ant script to generate javadoc and I just only wnt Ant to look for some classes based on a certain pattern, so I wrote: <javadoc access="public" source="1.6" sourcepath="src" destdir="dest" > <fileset dir="src" casesensitive="yes" defaultexcludes="yes"> <filename name="**/ABC*.java"/> </fileset> </javadoc> That means I only want Ant to look for source file that starts with "ABC" only and generate javadoc for these files. However, the results are awayls duplicate for each file starting with "ABC". Did I do something wrong? Thanks

  • Specification of Extended Properties in OleDb connection string?

    - by Monty
    At the moment I'm searching for properties for a connection string, which can be used to connect to an Excel file in readonly mode. Searching Google gets me a lot of examples of connection strings, but I can't seem to find a specification of all possibilities in the 'Extended Properties' section of the OleDb connection string. At the moment I've this: Provider = Microsoft.Jet.OLEDB.4.0; Data Source = D:\Data\Customers.xls; Extended Properties = 'Excel 8.0; Mode=Read; ReadOnly=true; HDR=Yes'; However... I've composed this by examples. So questions: 1. What is a decent source for OleDb Connection String documentation/reference? 2. Is the above connection string indeed connecting to the Excel file in readonly mode? Thanks!

  • Check to see if file transfer is complete

    - by Cymon
    We have a daily job that processes files delivered from an external source. The process usually runs fine without any issues but every once in a while we have an issue of attempting to process a file that is not completely transferred. The external source SCPs these files from a UNIX server to our Windows server. From there we try to process the files. Is there a way to check to see if a file is still being transferred? Does UNIX put a lock on a file while SCPing it that we could check on the Windows side?

  • How to share WinForms and code between 2 projects

    - by Richard Bysouth
    Hi I have a working Windows Forms app (split into an EXE and a few DLLs). Now I've been asked to look at creating another app (MyAppLite) that has only a very small subset of the functionality. Think of it as similar to MS Word Viewer vs. MS Word. Everything that I need to build MyAppLite is contained in the main solution - essentially I need to use a couple of the WinForms and whatever bits in the DLLs they call into. What would be the best way to do this? I was thinking of creating another Project in my solution for MyAppLite, then adding the necessary source files as links (using Add Existing Item Add As Link in Solution Explorer). I definitely wouldn't want to maintain 2 copies of the source code. FYI it's a .NET 2.0 VB app, using VS2008. thanks Richard

  • How to automize multiple projects build process by including digital signature of exe in Delphi?

    - by user193655
    After building a project group of 2 projects with Delphi (2009) I digitally sign the 2 exes using InstallAware Code signing, an exe that shipped with Delphi 2009. How is it possible to automize the digital signature, so when I build I can also attach digital signature. For digital signing I use a pvk (private key) file and an spc (Sw publisher certificate) file. Subquestion: Moreover I created a project group because I have 2 exes, but they are almost the same, the only thing that changes is the Application icon and the application name (one is ProductOne.dpr, the other is ProductTwo.dpr). In practice I have 2 brands of the same product, I have a single build but activation keys details activate one or the other, anyway now I was asked to change the icon and the filename, and for this I need to build 2 projects, activation key is not enough anymore to distinguish between the 2. Anyway if there is a way to do this from a single project it would be better.

  • C++ library for dealing with multiple HTTP connections

    - by JWood
    Hi, I'm looking for a library to deal with multiple simultaneous HTTP connections (pref. on a single thread) to use in C++ in Windows so it can be Win32 API based. So far, I have tried cURL (multi interface) which seems to be the most appropriate that I have found but my problem is that I may have a queue of 200 requests but I need to only run 4 of them at a time. This becomes problematic when one request may take 2 seconds and another may take 2 mins as you have to wait on all handles and receive the result of all requests in one block. If anyone knows a way round this it would be very useful. I have also tried rolling my own using WinHTTP but I need to throttle the requests so they would ideally need to be on a single thread and use callbacks for data which WinHTTP does not do. The best thing I've found which would solve all my problems is ASIHTTPRequest but unfortunately it's Mac OSX only. Thanks, J
