• Setting up Subsonic 3.0 on a ASP.NET web application on Visual Studio 2008

  - by Rob Paul

  I followed the steps on this tutorial video by at subsonic website. Everything seems to be self explanatory but when I copy the .tt files into my Visual Studio nothing happens. I have read other question relating to this problem on this website but they don't seem to fix this problem. I also went into the regedit to find out the generator key for .tt files and it is properly set. This is not a visual studio express or anything but a professional edition also I am trying to build a ASP.net web application and not a MVC application like the demo. Any help will be greatly appreciated. Thank You

• How to store a file on a server(web container) through a Java EE web application?

  - by Yatendra Goel

  I have developed a Java EE web application. This application allows a user to upload a file with the help of a browser. Once the user has uploaded his file, this application first stores the uploaded file on the server (on which it is running) and then processes it. At present, I am storing the file on the server as follows: try { FormFile formFile = programForm.getTheFile(); // formFile represents the uploaded file String path = getServlet().getServletContext().getRealPath("") + "/" + formFile.getFileName(); System.out.println(path); file = new File(path); outputStream = new FileOutputStream(file); outputStream.write(formFile.getFileData()); } where, the formFile represents the uploaded file. Now, the problem is that it is running fine on some servers but on some servers the getServlet().getServletContext().getRealPath("") is returning null so the final path that I am getting is null/filename and the file doesn't store on the server. When I checked the API for ServletContext.getRealPath() method, I found the following: public java.lang.String getRealPath(java.lang.String path) Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is the context path of this ServletContext. The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive). So, Is there any other way by which I can store files on those servers also which is returning null for getServlet().getServletContext().getRealPath("")

• Web service can't open named pipe - access denied

  - by Patrick

  Hi All, I've got a C++ service which provides a named pipe to clients with a NULL SECURITY_ATTRIBUTES as follows: hPipe = CreateNamedPipe( lpszPipename, PIPE_ACCESS_DUPLEX | FILE_FLAG_OVERLAPPED, PIPE_TYPE_BYTE | PIPE_READMODE_BYTE | PIPE_WAIT, PIPE_UNLIMITED_INSTANCES, BUFSIZE, BUFSIZE, 0, NULL); There is a dll which uses this pipe to get services. There is a c# GUI which uses the dll and works fine. There is a .net web site which also uses this dll (the exact same one on the same PC) but always gets permission denied when it tries to open the pipe. Any one know why this might happen and how to fix it? Also does anyone know of a good tutorial on SECURITY_ATTRIBUTES because I haven't understood the msdn info yet. Thanks, Patrick

• how to disable web page cache throughout the servlets

  - by Kurt

  To no-cache web page, in the java controller servlet, I did somthing like this in a method: public ModelAndView home(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView mav = new ModelAndView(ViewConstants.MV_MAIN_HOME); mav.addObject("testing", "Test this string"); mav.addObject(request); response.setHeader("Cache-Control", "no-cache, no-store"); response.setHeader("Pragma", "no-cache"); response.setDateHeader("Expires", 0); return mav; } But this only works for a particular response object. I have many similar methods in a servlet. And I have many servlets too. If I want to disable cache throughout the application, what should I do? (I do not want to add above code for every single response object) Thanks in advance.

• Web Setup Project - Getting the Current Machine Name

  - by Shane Kenney

  I've got a web setup project with a custom screen in it that asks for a machine name. Is there anyway to prepopulate this field with the current machines name? For the case that I need it for just including "Localhost" does not meet my requirements. "Environment.MachineName" will return the machine name within a code block which would be fine if I was needing it in a custom action. But it seems custom actions don't excecute until after you go through the installation wizard... So I cant actually use it. Anyway let me know what you think.

• Build Systems for PHP Web Apps

  - by macinjosh

  I want to start automating more of my web development process so I'm looking for a build system. I write mostly PHP apps on Mac OS X and deploy Linux servers over FTP. A lot of my clients have basic hosting providers so shell access to their servers is typically not available, however remote MySQL access is usually present. Here is what I want to do with a build system: When Building: Lint JavaScript Files Validate CSS Files Validate HTML Files Minify and concatenate JS and CSS files Verify PHP Syntax Set Debug/Production flags When Deploying Checkout latest version from SVN Run build process Upload files to server via FTP Run SQL scripts on remote DB I realize this is a lot of work to automate but I think it would be worth it. So what is the best way to start down this path? Is there a system that can handle builds and deploys, or should I search for separate solutions? What systems would you recommend?

• Intercept web requests from a WebView Flash plugin

  - by starkos

  I've got a desktop browser app which uses a WebView to host a Flash plugin. The Flash plugin makes regular requests to an external website for new data, which it then draws as fancy graphics. I'd like to intercept these web requests and get at the data (so I can display it via Growl, instead of keeping a desktop window around). But best I can tell, requests made by Flash don't get picked up by the normal WebView delegates. Is there another place I can set a hook? I tried installing a custom NSURLCache via [NSURLCache setSharedURLCache] but that never got called. I also tried method swizzling a few of the other classes (like NSCachedURLResponse) but couldn't find a way in. Any ideas? Many thanks!

• Axis error about runtime location

  - by Ayrad

  The error is: Exception occurred while reading or writing file {0}The Axis2 facets cannot be installed since the Axis2 runtime location has not been set. Go to the Web Services preference page and set the Axis2 runtime location under Axis2 Preferences. In the preferences mentioned, the location is set correctly and in fact, it says "Axis2 runtime loaded successfully" after loadign the correct runtime location. So what's going on? Any solutions other than re-installing eclipse or creating a new workspace? I am using Axis2 1.4.1 and eclipse.

• Creating a data driven web front end quickly

  - by Ilya

  Over the last few years, I can't count how many web front ends I've had to create over a relatively simple database schema to fasciliate data entry. I have to imagine that someone out there has written a framework I can use to simplify the creation of these kind of simple GUIs. Doing a quick google, the following look like the key players in .net: ASP.Net dynamic data framework SubSonic NakedObjects for .net Has anyone worked with any of these and have any preferences? More importantly, are there other frameworks that would be good to evaluate in this space?

• Eclipse Basic Web Development?

  - by Sean Ochoa

  I want to start doing web development with Eclipse. Not Java, tomcat, axis2, or anything else anymore complicated than basic XHTML / JS / CSS development, at this time. Problem 1: I realize that it can edit those files, but its trying to manage my HTML docs as part of "my workspace", and all I want it to do is manage the files as part of my local www server HTdocs directory. Problem 2: I would like to edit WYSIWYG-style, if possible. I tried installing a plug-in for that, but I wasn't able to get w4 toolkit to function properly. This would really help me to speed up development, I think. Follow-up: I've installed WTP and its dependencies (except for the tests portion, which had install problems due to dependencies that were seemingly irreconcilable).

• Pros and Cons on where to place business logic: app level or DB

  - by Juri

  Hi, I always again encounter discussions about where to place the business logic: inside a business layer in the application code or down in the DB in terms of stored procedures. Personally I'd tend to the 1st approach, but I'd like to hear some opinions from your part first, without influencing you with my personal views. I know there doesn't exist a one-size-fits-all solution and it often depends on many factors, but we can discuss about that. Btw, we are in the context of web applications and our current approach is to have UI layer which accepts UI input and does a first, client-side validation Business layer with a number of service-classes which contains the business logic including validation for user input (server-side) Data Access Layer which calls stored procedures from the DB for doing persistency/read operations Many people however tend to move the business layer stuff (especially regarding the validation) down to the DB in terms of stored procedures. What do you think about it? I'd like to discuss.

• Are there such things as Email Hooks?

  - by viatropos

  After hearing about git commit hooks, I was thinking maybe there are such things as email hooks... Is it possible for me to build a program that says "hey, you just received an email, now run this ruby script"? Something like a GMail Web Hook. Is there anything out there like that? I mean I could build a cron thing that checked my email all the time, but maybe there's a more formal way. Looking for an online email system to do this with, not say my Mac Mail.

• Parsing boolean from configuration section in web.config

  - by Bloopy

  I have a custom configuration section in my web.config. One of my classes is grabbing from this: <myConfigSection LabelVisible="" TitleVisible="true"/> I have things working for parsing if I have true or false, however if the attribute is blank I am getting errors. When the config section tries to map the class to the configuration section I get an error of "not a valid value for bool" on the 'LabelVisible' part. How can I parse "" as false in my myConfigSection class? I have tried this: [ConfigurationProperty("labelsVisible", DefaultValue = true, IsRequired = false)] public bool? LabelsVisible { get { return (bool?)this["labelsVisible"]; } But when I try and use what is returned like so: graph.Label.Visible = myConfigSection.LabelsVisible; I get an error of: 'Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?) Thanks for any suggestions!

• Best Pratice to Implement Secure Remember Me

  - by Yan Cheng CHEOK

  Sometimes, I came across certain web development framework which doesn't provide authentication feature as in Authenication ASP.NET I was wondering what is the security measure needs to be considered, when implementing "Remember Me" login feature, by hand coding? Here are the things I usually did. 1) Store the user name in cookie. The user name are not encrypted. 2) Store a secret key in cookie. The secret key is generated using one way function based on user name. The server will verify secret key against user name, to ensure this user name is not being changed. 3) Use HttpOnly in cookie. http://www.codinghorror.com/blog/2008/08/protecting-your-cookies-httponly.html Any things else I could miss out, which could possible lead a security hole.

• Debugging ASP.NET on a built-in web server suddenly stops

  - by Anton Gogolev

  I have Windows Server 2008 (64-bit), VS 2008 with its built-in webserver and an ASP.NET MVC 1.0 webapp. All I'm trying to do is to debug said app. I have a bunch of breakpoints, but they behave in a very strange way. When I fist start a debugging session with F5 and hit a breakpoint, the debugger stops just fine. However, after serveral F10s/F11s debugging suddenly "stops" (no exceptions at that time), but neither VS detaches from browsers' process, nor webapp execution stops: Visual Studio stays attached, and web request continues executing as usual. I tried various browsers (Chrome, Firefox, IE), but to no avail. What do I do to solve this? It really drives me insane.

• ASP.NET How expensive is it to call an Application Variable many times?

  - by Matias Nino

  The short of it is: Is it costly to check an Application Variable such as Application("WebAppName") more 10-20 times each time a page loads? Background: (feel free to critique) Some includes in my site contain many links and images which cannot use relative urls due to their inclusion in different paths. Hence these includes contain frequent instances of <img src="<%=Application("Webroot")%>images\image.gif"> Is it expensive to keep calling an Application variable like this? Should I just put the Application value in some local variable to use where needed? IMPORTANT NOTE: I need my webapp to run fine on a server whether it be in the root web ("/") or in a virtual subweb ("/app"). Thanks in advance for any wisdom shared.

• Powershell call web service on new email event (Exchange 2010)

  - by Mike Mengell

  I have Exchange 2010 and I need to run a process using web services against every new email to come in to a mailbox. The process will basically add the email to an internal task list. Can I use Powershell for this? Having never used Powershell before I don't really have a clue on it's capabilities. If not can anyone suggest another way of doing this other than monitoring the mailbox every X seconds. Really I'd like it event based so if no new mail then no processing. Cheers, Mike

• Jquery roller/toggle effect

  - by Paul Higgins

  Hi, I'm looking for a "roller toggle" in jquery (ideally using a plugin). If I have the following HTML: <ul> <li>Option 1</li> <li>Option 2</li> <li>Option 3</li> </ul> I would like the first option to be displayed and the others hidden. Each time I "tap/click" on an option it displays the next and loops around to the first one after the last one. When used on a mobile web device I'd like it respond to swipe up/down events and appear like a "roller" (i.e. using a slide up/down effect). Too much to ask? Hopefully not, any pointers appreciated. Thanks, Paul

• ASP.net SessionState Error in Design Mode

  - by stringo0

  I'm getting a weird error in the design view for a user creation page for 2 controls: Error Creating Control - wCreateUser Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. (There's some more) I've done both of these, but I'm still getting the error in design mode. The controls work fine when compiled, and on the live site - this is just in the Visual Web Developer 2010 Design view for the page. Any ideas as to how I can resolve this? Thanks!

• Blackberry app stuck trying to access a server.

  - by Tejaswi Yerukalapudi

  Hi, I've built a ASP.NET webservice and I'm trying to access it from a Blackberry. I've been testing it out with multiple devices and the simulator and it works fine, but there's just the one Blackberry 9000 (It's not the model, I've tried it out with another Blackberry 9000), and it's stuck waiting for a response from the server. Relevant section of the code that accesses this - System.out.println("IN ntwk access thread, start point"); HttpConnection connection = (HttpConnection)Connector.open(serviceURL + WSNAME); connection.setRequestMethod(HttpConnection.POST); connection.setRequestProperty("Content-type", "application/x-www-form-urlencoded"); connection.setRequestProperty("Content-length", Integer.toString(postData1.length)); OutputStream requestOutput = connection.openOutputStream(); requestOutput.write(postData1); requestOutput.close(); final int responseCode = connection.getResponseCode(); if(responseCode!= HttpConnection.HTTP_OK) { //Process the error condition } // Request succeeded process the data. It seems to be getting stuck after connection.getResponseCode(). Is there some way I can verify what's going wrong with this particular device? Thanks, Teja
