  • How Can I Create Reports in a Custom C#.NET Windows Application? - General Question

    - by user311509
    Assume i have a custom Windows application written in C#. This application has only the following functionalists, add, edit, delete and view. For example, a user can add a sale, change sales record, delete a sale record or view the whole sales record. I need to add some reporting functionalists e.g. i want a user to print the sales of a certain customer from 2008 to 2009 into pdf, what all products a certain customer has purchased from us and so on. I will only include the basic common report requests that are usually needed in the office. Any other kind of reports that are requested inconsistently, i would do it manually from my side at the back end and send the results manually to the requester. What i would do is: If a user wants more info of a certain customer, a special window box appears for that customer. This window box will have different controls that allows user to request more info such as, print customer purchases from ..... to ..... (user chooses the dates) and user will view results in pdf or so. Of course, at the back scene i will write an appropriate SQL Query with parameters that meets a certain function. Is this how it should be done? I have heard about SQL Reporting, i don't know anything about it yet. I will check it out. Anyhow, your suggestions won't harm. I'm still a student, so i don't have practical experience yet. I hope my question is clear enough. Thank you.

  • How to get a service to listen on port 80 on Windows Server 2003

    - by Miky D
    I've coded a custom windows service that listens on TCP port 80 but when I try to install it on a Windows Server 2003 machine it fails to start because some other service is already listening on that port. So far I've disabled the IIS Admin service and the HTTP SSL service but no luck. When I run netstat -a -n -o | findstr 0.0:80 it gives me the process id 4 as the culprit, but when I look at the running processes that process id points to the "System" process. What can I do to get the System process to stop listening on port 80 and get my service to listen instead? P.S. I should point out that the service runs fine if I install it on my Windows XP or Windows 7 development boxes. Also, I should specify that this has nothing to do with it being a service. I've tried starting a regular application that attempts to bing to port 80 on the Windows Server 2003 with the same outcome - it fails because another application is already bound to that port.

  • WCF service for receiving image

    - by elgrego
    What is the best way to create a webservice for accepting an image. The image might be quite big and I do not want to change the default receive size for the web application. I have written one that accepts a binary image but that I feel that there has to be a better alternative.

  • technologies beside scaling web applications in a distributed nature

    - by wik
    Hello, I am interested in theory to scale web applications in a distributed nature, i.e. when there is some platform/stack can be extended by others applications running on different servers, etc. I am researching this field and feels the lack of the right keywords :) Interesting concepts found so far: opensocial through API, like shopify does (shopify it's a hosted ecommerce solution) semantic web not quite sure about this one Am I on the right way or am I lost anything? :) Thanks.

  • How to efficiently manage files on a filesystem in Java?

    - by Tuukka Mustonen
    I am creating a few JAX-WS endpoints, for which I want to save the received and sent messages for later inspection. To do this, I am planning to save the messages (XML files) into filesystem, in some sensible hierarchy. There will be hundreds, even thousands of files per day. I also need to store metadata for each file. I am considering to put the metadata (just a couple of fields) into database table, but the XML file content itself into files in a filesystem in order not to bloat the database with content data (that is seldomly read). Is there some simple library that helps me in saving, loading, deleting etc. the files? It's not that tricky to implement it myself, but I wonder if there are existing solutions? Just a simple library that already provides easy access to filesystem (preferrably over different operating systems). Or do I even need that, should I just go with raw/custom Java?

  • Consuming an RPC/encoded Web Service in .NET

    - by Timmy O' Tool
    I'm trying to build the proxy class for a web service using the wsdl Executing this command: wsdl [http://WSDL_URL] I'm getting Warning: This web reference does not conform to WS-I Basic Profile v1.1. R2706: A wsdl:binding in a DESCRIPTION MUST use the value of "literal" for the use attribute in all soapbind:body, soapbind:fault, soapbind:header and soapbind:headerfault elements. ... Error: Cannot find definition for http://schemas.xmlsoap.org/wsdl/:BouBinding. Service Description with namespace http://schemas.xmlsoap.org/wsdl/ is missing. Parameter name: name The author of the web service told me that the SOAP protocol is RPC/encoded. Is there is any way to generate a proxy class for this?

  • How to use log4j for a axis2 webservice

    - by KItis
    I have created a simple axis2 webservice to understand logging functionality in a webservice. in this sample webservice, when a client calls this webservice, first it reads the log4j.property file. then i can see the logs being printed on console. but i have included file appender too into the property file. but i can not file the log file any where in my sample webapplication. i am using tomcat to run the webservice. following is webservice interface method called by client. package test; import java.io.IOException; import java.io.InputStream; import java.util.Properties; import org.apache.log4j.BasicConfigurator; import org.apache.log4j.Logger; import org.apache.log4j.PropertyConfigurator; public class WSInterface { static final Logger logger = Logger.getLogger(WSInterface.class); public String log4jTest(String input){ InputStream inputStream = this.getClass().getClassLoader() .getResourceAsStream(input); Properties properties = new Properties(); System.out.println("InputStream is: " + inputStream); //load the inputStream using the Properties try { properties.load(inputStream); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } PropertyConfigurator.configure(properties); logger.debug("Hello World!"); Class myclass = WSInterface.class; String url = myclass.getResource("WSInterface.class").toString(); String output = ""; return url; } }

  • Why use Soap as authenitcation in webservice?

    - by chobo2
    Hi I am looking at this tutorial http://www.codeproject.com/KB/cpp/authforwebservices.aspx and I am wondering what the reason for using authentication through soap is? Like why not just pass the username and password through the parameters instead? Is it more secure to do it like the way the guy is in the tutorial verus just using passing it through as parameters? Thanks

    Hi, I have an application in C# (2.0 running in XP embedded) that is using a watchdog that is implemented as a Windows Service. When the device boots, this service typically takes some time to start. I'd like to check, from my code, if the service is running. How can I accomplish this?

  • Can I return JSON from an .asmx Web Service if the ContentType is not JSON?

    - by Click Ahead
    I would like to post a form using ajax and jquery to a .asmx webservice and return the value from the webservice as JSON. I'm using ASP.NET 4.0. I know that in order to return JSON from a webservice the following needs to be set (1) dataType: "json" (2) contentType: "application/json; charset=utf-8", (3) type: "POST" (4) set the Data to something. I have tested this and it works fine (i.e. my webservice returns the data as JSON) if all *four are set*. But, lets say in my case I want to do a standard form post i.e. test1=value1&test2=value2 so the contentType is not JSON but I want back JSON {test1:value1}. This doesn't seem to work because the contentType is "application/x-www-form-urlencoded" not "application/json; charset=utf-8". Can anyone tell me why I can't do this? It seems crazy to me that you have to explicitly send JSON to get JSON back, yet if you don't use JSON (i.e. post urlencoded contenttype) then the webservice will return XML. Any insights are greatly appreciated :)

  • 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.

  • Running an existing LINQ query against a dynamic object (DataTable like)

    - by TomTom
    Hello, I am working on a generic OData provider to go against a custom data provider that we have here. Thsi is fully dynamic in that I query the data provider for the table it knows. I have a basic storage structure in place so far based on the OData sample code. My problem is: OData supports queries and expects me to hand in an IQueryable implementation. On the lowe rside, I dont have any query support. Not a joke - the provider returns tables and the WHERE clause is not supported. Performance is not an issue here - the tables are small. It is ok to sort them in the OData provider. My main problem is this. I submit a SQL statement to get out the data of a table. The result is some sort of ADO.NET data reader here. I need to expose an IQueryable implementation for this data to potentially allow later filtering. Any ide ahow to best touch that? .NET 3.5 only (no 4.0 planned for some time). I was seriously thinking of creating dynamic DTO classes for every table (emitting bytecode) so I can use standard LINQ. Right now I am using a dictionary per entry (not too efficient) but I see no real way to filter / sort based on them.

  • Consume restful webservice through web proxy

    - by Chico
    Hello, I'm trying to consume a restful webservice in java using the Apache Wink framework through my school web proxy requiring authentification ClientConfig clientConfig = new ClientConfig(); clientConfig.proxyHost("proxy.school.com"); clientConfig.proxyPort(3128); //nothing to set username and password :( RestClient client = new RestClient(clientConfig); Resource resource = client.resource("http://vimeo.com/api/v2/artist/videos.xml"); String response = resource.accept("text/plain").get(String.class); I've also tried to use the BasicAuthSecurityHandler but it seems to be used to authenticate directly to a web server, not the web proxy BasicAuthSecurityHandler basicAuthHandler = new BasicAuthSecurityHandler(); basicAuthHandler.setUserName("username"); basicAuthHandler.setPassword("password"); config.handlers(basicAuthHandler); It still fail with a HTTP 407 error code : Proxy Authentication Required. I've googled the best I could, nothing came up better to consume a webservice from a Java client through a web proxy, if someone has another idea, feel free to respond

  • SSIS 2005 - How to Import a Fixed Width Flat File?

    - by Greg
    I have a flat file that looks something like this: junk I don't care about \n \n columns names\n val1 val2 val3\n val1 val2 val3\n columns names \n val1 val2 val3\n I only care the lines with values. These value lines are all fixed width format and have the same line length. The other junk lines and column names can have any line width. When I try the flat file fixed width option or the ragged right option the preview looks all wrong. Any ideas what the easiest way to get this into SSIS is?

  • How do I debug an ASP.NET web service in Visual Studio?

    - by Ben McCormack
    I have an ASP.NET .ASMX web service that I converted to .NET 4.0 with VS 2010 and is hosted in an IIS 7.5 (Windows 7) application pool. I have a simple html page that I use to make the AJAX request to the web service. How can I debug what's going on in the web service in Visual Studio? Because the HTML ajax request doesn't seem "tied in" to the web service, which is located on my local IIS service, I can't figure out how to debug it.

  • Tomcat 5.5 as service on Windows Server 2008 64bit

    - by netterdotter
    Hi, Has anybody managed to get Tomcat to run as a service on Win2008 64bit? I need it for a 3rd party component that my site relies on. It works fine otherwise, but I just can't get it to run as a service. I've tried all the googling I can, and experimented with various 64bit tomcat.exe / tomcatw.exe without success. Upgrading to Tomcat 6 didn't help either. I'm running Java 1.5 64bit.

  • Avoid writing SQL queries altogether in SSIS

    - by Jonn
    Working on a Data Warehouse project, the guy that gave us the tutorial advised that we stick to using SQL queries over defining a lot of data flow transformations, citing points like it'll consume a lot of memory on the ETL box so we'd rather leave the processing to the DB box. Is this really advisable? Where's the balance between relying on GUI tools over executing a bunch of SQL scripts on your Integration package? And honestly, I'd like to avoid writing SQL queries as much as I can.
