• CF Framework Targeting.

  - by En

  Hi if a smart device project is set to target CF 2.0, Windoes CE 5.0. Should this same application run on Windows Mobile 6 with CF 3.5 installed? I was able to install it (the CF 2 app), but when running receive an error stating that the assemblies could not be loaded and that CF might not be installed. This has led me to belive that smart device projects wil ONLY work on the framework they target, not any versions lower or greater. Any help would be greatly appreciated.

• How to create an eclipse plug-in?

  - by Amir Rachum

  I've decided that as a pet project meant for learning, I would create a new Eclipse plug-in that, for a given class, takes all private member names and adds a prefix to their name (it doesn't matter to me if it can already be done or not, this is meant to be a learning experience). I have never developed an Eclipse plug-in and I'm not sure where to begin. Do I need to install some application for this development? How does it work? Where do I begin? I did a Google search but all the tutorials and results I found were old and referred to antiquated versions of Eclipse, so I'm not sure if they're still accurate.

• How do I load SciLexer.dll in Visual Studio 2008 Designer, on Windows 7 64-bit?

  - by Filini

  We develop a WinForm application using Scintilla.NET (1.7) component, which uses SciLexer.dll (unamnaged). At run-time, we distribute both 32bit and 64bit SciLexer.dll, and we load the correct one when the application starts (everything works fine). On our new development environments (Windows 7 64-bit), all our solutions build and run just fine, but the WinForm visual designer does not load our forms/controls which use Scintilla.NET, because it cannot load the correct SciLexer.dll: Window class name is not valid. at System.Windows.Forms.NativeWindow.WindowClass.RegisterClass() at System.Windows.Forms.NativeWindow.WindowClass.Create(String className, Int32 classStyle) at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp) at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.Control.get_Handle() at Scintilla.ScintillaControl.SendMessageDirect(UInt32 msg, IntPtr wParam, IntPtr lParam) at Scintilla.ScintillaControl.SendMessageDirect(UInt32 msg) at Scintilla.ScintillaControl.get_CodePage() at Scintilla.ScintillaControl..ctor(String sciLexerDllName) at Scintilla.ScintillaControl..ctor() Where does Visual Studio 2008 look for unmanaged libraries? I tried putting the 64-bit SciLexer.dll in SysWOW64, in the folder where ScintillaNET.dll is referenced, adding a folder in PATH system variable, adding a folder reference in the project, but I keep getting this error. Any help is appreciated.

• Problem with View - it does not refresh after db update

  - by crocodillez

  Hi, I am working with small ASP.NET MVC project - online store. I have addToCart method which adds selected product to cart - it updates cart table in my db and showing cart view with its content. But I have problems. While db is updating correctly the view does not. I see that quantity of the product in my db is incremented correctly but quantity in view is not changed. I have to stop debugging my app in visual studia and restart it - then my view is showing correct data. What can be wrong?

• How-to build a droplet application in Xcode4?

  - by Josh

  In Xcode3 there used to be a template to build "Droplet" Applications (head/nibless apps that would throw whatever dropped at them at an "on open" Applescript method). In Xcode4 this template is unfortunately gone. What are the required steps to setup an xcode4 droplet project? modify the info.plist i guess to make the app handle drops get rid of the nib (also involves changes in main.m and both AppDelegate.h and AppDelegate.m i guess) Maybe somebody even still has Xcode3 installed and could create an empty applescript droplet app and upload it somewhere? that would be very interesting. thanks! (or is there maybe even a way to export an app bundle created with the AppleScript Editor to Xcode?)

• Eclipse: How to build an executable jar with external jar?

  - by Ben

  Hi all, I am trying to build an executable jar program which depends on external jar downloaded. In my project, I included them in the build path and can be run and debug within eclipse. When I tried to export it to a jar, I can run the program but I can't when I try to press a button which includes function calls and classes from the external jar. I have edited the environment variables (Windows XP) CLASSPATH to include paths of all the external jar, but it doesn't work. A point to note is that I got compile warnings while exporting my executable jar, but it doesn't show up any description about the warnings. Would someone kindly provide a thorough guide on how to include an external jar program using eclipse? Best regards, KWAN Chiu Yin, Ben

• VB Script - Unmount USB drive

  - by user736887

  I have tedious project coming up. I need to insert a usb flash drive into a computer, then copy over three files to that drive, and then unmount it and repeat 3000 times (literally). I was hoping to come up with some VB Script that can reduce my input to just 1.) insert the usb and 2.) double click on the .vbs file and remove the usb flash drive. I figure it isnt too difficult to come up with the copy and paste part of the code as long as I am inserting the usb into the same port every time. Is this assumption correct? However, the real problem is unmounting/ejecting the usb drive. Is there any simple VB Script code that can accomplish this? Thank you, -Corey

• Create and access folder outside Apache Tomcat webapps folder

  - by Padur

  My web application requires functionality where end users can upload content, that can be later downloaded or viewed by others, the problem with current scheme is If I create such folder as part of your web project under webapps, every time I do deploy your web application (*.war), the content of that directory will be lost (or overridden). I think the best way to accomplish that is to create folder outside of standard tomcat webapps and access it from there, not sure how to do. Please point in correct direction. I am using Tomcat 4.x soon will be moving to 6.x. -Padur

• Current ways to do data binding in .NET 3.5 with C# 3.0 and WinForms

  - by kryptic

  Hello Everyone, I have an existing C# 3.0 WinForms project with .NET 3.5 that talks to a MySQL database. I would like to use data binding (I'm new to this, so I've been doing all of the UI updates manually) to simplify things. I followed a link from this question to this article which mentions using a DataSet but also follows up with "my view on this topic is strongly in favor of Business Objects." Also that was with .NET 2.0. What are the current methods to use data binding with a WinForms application? What are their advantages in terms of simplicity, how much additional code is necessary, etc. For reference, I use an ORM approach to build objects with public properties from a database. I want to map these properties for each object onto UI elements like TextBoxes. There could be many properties for an object so I want to simplify the code to do this.

• Are there any syntax errors in the code snippet here?

  - by Mask

  typedef union YYSTYPE { int64_t iConst; // constant value float fConst; // constant value int iAttrLocator; // attribute locator (rowitem for int/float; offset+size for bits) int iFunc; // function id int iNode; // node index } YYSTYPE; It looks valid to me,but the cdt reports the following for the line int64_t iConst;: Multiple markers at this line: - syntax error before "int64_t" - no semicolon at the end of structure or union There are two files that defines int64_t,one is within the project itself(sphinxstd.h),the other is the MinGW/include/stdint.h,is it caused by this conflict?

• Unable to view values of variables while debugging

  - by RexM

  I'm trying to debug portions of the current application I'm working on, however when I try and check the value of a property/variable I get the error: Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized. This is just a regular ASP.NET project. In some portions of the application I can view the properties and variables perfectly fine. I haven't figured out what's different about the blocks of code that I can and can not see the values of the variables in.

• Using Google AppEngine app as a OAuth provider

  - by Alistair

  Hi, I'm using the Google AppEngine 1.3.4 SDK which offers to allow your application to act as a OAuth service provider (http://code.google.com/appengine/docs/python/oauth/). Setting up a standard application on my localhost and using the following: Request URL /_ah/OAuthGetRequestToken Authorize URL /_ah/OAuthAuthorizeToken Access Token URL /_ah/OAuthGetAccessToken The client application just gets sent to a page requesting to grant OAuth access even though no user is logged in. Clicking 'Grant access' results in a message saying 'OAuth access granted' with no tokens or anything exchange. Can't see how this could work when it's not even prompting for a login. As this functionality is quite new I can't find much out there. I've created a OAuth provider before in Rails and know that you need a Consumer Key and Secret, something that seems to be lacking in GAE? Any ideas on how to get OAuth working in a sample GAE project are most welcome.

• How do find the longest path in a cyclic Graph between two nodes?

  - by Nazgulled

  Hi, I already solved most the questions posted here, all but the longest path one. I've read the Wikipedia article about longest paths and it seems any easy problem if the graph was acyclic, which mine is not. How do I solve the problem then? Brute force, by checking all possible paths? How do I even begin to do that? I know it's going to take A LOT on a Graph with ~18000. But I just want to develop it anyway, cause it's required for the project and I'll just test it and show it to the instructor on a smaller scale graph where the execution time is just a second or two. At least I did all tasks required and I have a running proof of concept that it works but there's no better way on cyclic graphs. But I don't have clue where to start checking all these paths...

• Client side templating with unknown variables

  - by Eirik Johansen

  Our company has an intranet consisting of several e-mail templates filled with variables (like [[NAME]], [[PROJECT]] and so on). I was thinking of implementing some sort of client side templating to make it easier to replace these variables with actual values. The problem is that among all the client side template solutions I've located so far, all of them seem to assume that the JS code knows all the template variables that exist in the markup, and none of them seem to be able to fetch a list of variables defined in the markup. Does anyone know of any solutions/plugin which makes this possible? Thanks in advance!

• ASP.Net MVC Where do you convert from Entities to ViewModels?

  - by Pino

  Title pretty much explains it all, its the last thing I'm trying to work into our project. We are structured with a Service Library which contains a function like so. /// <summary> /// Returns a single category based on the specified ID. /// </summary> public Category GetCategory(int CategoryID) { var RetVal = _session.Single<Category>(x => x.ID == CategoryID); return RetVal; } Now Category is a Entity (We are using Entity Framework) we need to convert that to a CategoryViewModel. Now, how would people structure this? Would you make sure the service function returned a CategoryViewModel? Have the controller pull the data from the service then call another function to covnert to a view model?

• Are there any widespread, modern Java coding conventions?

  - by brianegge

  Sun's "Code Conventions for the Java Programming Language" was last updated April 1999. Ten years later a lot has changed in the language, as well as general usage patterns. Are there more up to date, widely adopted standards? Most guidelines omit specifying file encoding and line endings. Sun recommends mixed tabs and spaces. The Eclipse IDE defaults to Eclipse's standard, which is tabs only. The Maven style guide is spaces only. Many style guides, such as JBoss, follow Sun's guidelines, but prefer K&R braces instead of OTBS. Each Apache project has it's own style guide, with slight differences between each one.

• Dynamic IMAP/Pop3 Email Address Creation

  - by Vadi

  I have a requirement in my project to create dynamic email address on the fly. For example, similar to flickr has the option of uploading photos (or blogger.com has an option of rececing blog posts in predefined email addresses). The email address can be like "[email protected]", once this email address is created what ever the incoming mails will be processed based on certain scenarios. My questions are: What are the solutions available for having our own IMAP/POP3 Server in Windows? Exchange is not an option though, any commercial softwares will do. Is there any way we can have one real email box and that will be masked with alphanumeric email addresss to minimize the creation of email addresses.

• JAXB, Netbeans and Interface Insertion Plugin

  - by segolas

  Hi, I can't get my generated classes to implements any interface. This is my xml schema file: xmlns:jxb="http://java.sun.com/xml/ns/jaxb/" xmlns:ai="http://jaxb.dev.java.net/plugin/if_insertion" jxb:extensionBindingPrefixes="ai" <xs:element name="header"> <xs:annotation> <xs:appinfo> <ai:interfaces check="1"> utility.RuleInterface </ai:interfaces> </xs:appinfo> </xs:annotation> <xs:complexType> bla bla bla </xs:complexType> I checked the "Extension" option in the JAXB options and I hav added the xjc-if-ins.jar to the "Libraries" section of my project Properties. But the generated Header class doesn't implements the utility.RuleInterface. I can figure out what am I doing wrong... Is it something missing? Any idea? regards, Segolas

• Migrate existing ROR app to GAE

  - by zengr

  I have managed to run a basic rails app1 on App Engine using: http://gist.github.com/268192 So, on my basic app2, I install CE, which works fine on local machine. (communityengine.org) But, when I follow the same steps on my actual app2, where community_engine plugin is installed and all the gems are frozen, the app engine installer script asks for to over write various files like boot.rb, routes.rb, which I don't allow. So, as expected, when I publish the rails + ce app to GAE, it's not published and it also screws the local installation of CE on app2. So, the problem is obvious, CE uses ActiveRecord, and GAE uses DataMapper. So, my question can also be rephrased as: Can we migrate an existing ROR App using Active Record to GAE which uses DataMapper? PS: This is my first project on ROR and GAE.

• Android "gen" folder and SVN - bitter enemies.

  It seems that I accidentally checked in my "gen" folder from an Android project (this folder contains the R.java generated class). When I realized I did this I deleted it from SVN and tried to ignore it. Now I am now getting the error... "Could not add gen to the ignore list! Working copy 'C:\code\guru' locked. When I try to run a cleanup command I get this... Cleanup failed to process the following paths: -C:\code\guru 'C:\code\guru\gen' is not a working copy directory.

• Web service does not accept input

  - by Germstorm

  I am working on a simple .Net 4.0 webservice. I created one method, which accepts a string input. I run the project in Debug mode so a page opens in my browser where I can enter an input and invoke the method of the service. Unfortunately I am getting the following error: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (xmlData=&quot;&lt;?xml version=&quot;1.0&quot; ...&quot;). at System.Web.HttpRequest.ValidateString(String value, String collectionKey, RequestValidationSource requestCollection) at System.Web.HttpRequest.ValidateNameValueCollection(NameValueCollection nvc, RequestValidationSource requestCollection) at System.Web.HttpRequest.get_Form() at System.Web.Services.Protocols.HtmlFormParameterReader.Read(HttpRequest request) at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters() at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest() I tried adding to the web.config. What can I do?

• LNK1106 with big binary resource

  - by E Dominique

  I have a rather huge .dat-file (896MB) included as a BIN resource in my project. Now I get a LNK1106 link error ("fatal error LNK1106: invalid file or disk full: cannot seek to 0x382A3920".) I use Visual Studio 2005 under Windows XP, and have tried on a 4GB RAM machine with high Virtual Memory settings and lots of disk space. I have tried a number of different optimization flags, but to no avail. Does anyone have a clue? EDIT: I have narrowed it down to a specific size of the compiled resource. If the .res file is 544078588 bytes (about 518.9MB) or larger, the error occurs. If it is smaller it works just fine. Still no solution, though...

• Problems with South/Django: not recognizing the Django App

  - by christmasgorilla

  I've got a Django project on my machine and when I try to use South to migrate the data schema, I get several odd errors. Example: $ python manage.py convert_to_south thisLocator /Library/Python/2.6/site-packages/registration/models.py:4: DeprecationWarning: the sha module is deprecated; use the hashlib module instead import sha /Users/cm/code/thisLocator/../thisLocator/batches/models.py:6: DeprecationWarning: the md5 module is deprecated; use hashlib instead import md5 There is no enabled application matching 'thisLocator'. I've followed the South documentation. Settings.py has it in the installed apps, I can run import south from the manage.py shell. Everyone else on my team is calling the app thisLocator. Am I doing something really stupid?

• Portable applications for phones?

  - by peoro

  What's the best way to write an application in order to get it working on the several phones out there (iPhone, symbian-based, xpPhone, and so on)? The idea I have in mind is that of writing a few interfaces to abstract from phone-dependent stuff (ie: some Input/Output interfaces), implementing such interfaces on the several phones and then writing an application that doesn't use any phone-dependent thing. But is this really possible? What would be the language I should choose for my interfaces and applications? (would love to use C++, hopefully even with GCC extensions) Is there any project that aims to offer what I need? (maybe something like SDL?)
