• Flash - Uploading to and Downloading from localhost

  - by Md Derf

  I have an online flash application that acts as a front end for a server application built in delphi. The server can be installed/used on a remote computer or a personal version can be downloaded and the Flash app pointed at localhost to use it. However, Flash has issues with using the POST and GET functions on the localhost, which makes uploading data files and downloading results files difficult. To get past the difficulty with downloading results files I'm planning to just have the server app serve the results file as an attachment and have the Flash app open the address of the file up in another browser window using external interface. First off, is this likely to cause similar security issues? I.E. Flash will see "localhost" in the external interface call and stop it from working the same as when I try to use POST/GET functions with localhost? Secondly, for upload this seems just a bit little trickier, I'm planning on doing something similar, having flash use external interface to open a php script for a file upload. Is this feasible and, again, will Flash still have security issues? Lastly, if anyone knows how to get flash to execute POST and GET functions with localhost addresses, I'd love to have that information to avoid all this jumping through hoops.

• Suggestions for entering mobile development -- pure iPhone SDK, Andorid SDK. Mono Touch or Titanium?

  - by Tom Cabanski

  I am entering mobile development. I have been working primarily in .NET since 1.0 came out in beta. Before that, I was mostly a C++ and Delphi guy and still dabble in C++ from time to time. I do web apps quite a bit so I am reasonably proficient with Javascript, JQuery and CSS. I have also done a few Java applications. I started web programming with CGI and live mostly in the ASP.NET MVC world these days. I am trying to decide on which platform/OS and tool to select. I am concerned with the size of the market available for my applications as well as the marketibility of the skills I will pick up. The apps I have in mind would work on both phones and pads. Some aspects of what I have in mind will play better on the bigger screens that will be available on pads. Here are the options I am considering: Apple iPhone/iPad using pure Apple SDK (Objective-C) Apple iPhone/iPad using Mono Touch (C#) Android using pure Android SDK (Java) Multiple platforms using something like Titanium to generate native apps from web technologies (HTML, CSS and Javascript) Multiple platforms using HTML5 web applications that run in the browser (HTML, CSS and Javascript). Which option would you choose? Do you have a different suggestion? What are the pros and cons?

• I have two choices of Master's classes this fall. Which is the most useful?

  - by ahplummer

  (For background purposes and context): I am a Software Engineer, and manage other Software Engineers currently. I kind of wear two hats right now: one of a programmer, and one as a 'team lead'. In this regard, I've started going back to school to get my Master's degree with an emphasis in Computer Science. I already have a Bachelor's in Computer Science, and have been working in the field for about 13 years. Our primary development environment is a Windows environment, writing in .NET, Delphi, and SQL Server. Choice #1: CST 798 DATA VISUALIZATION Course Description: Basically, this is a course on the "Processing" language: http://processing.org/ Choice #2: CST 711 INFORMATICS Course Description: (From catalog): Informatics is the science of the use and processing of data, information, and knowledge. This course covers a variety of applied issues from information technology, information management at a variety of levels, ranging from simple data entry, to the creation, design and implementation of new information systems, to the development of models. Topics include basic information representation, processing, searching, and organization, evaluation and analysis of information, Internet-based information access tools, ethics and economics of information sharing.

• How to import a class from default package

  - by mykhaylo

  Hi, I am using Eclipse 3.5 and I have created a project with some package structure along with the default package. I have one class in default package - Calculations.java and I want to make the use of that class in any of the package (for instance in com.company.calc). When I try to make the use of the class which is default package, its giving me compile error. Its not able to recognise the class in default package. Where is a problem? Calculations.java - source code public class Calculations{ native public int Calculate(int contextId); native public double GetProgress(int contextId); static { System.loadLibrary("Calc"); } } I can put my class in any other package. This class has some native method which is implemented in Delphi . If I put that class in any of the folder,I will have to make the change that DLL which I want to avoid(really - I can not). Thats why I put my class in the default package.

• SQL Server: What locale should be used to format numeric values into SQL Server format?

  - by Ian Boyd

  It seems that SQL Server does not accept numbers formatted using any particular locale. It also doesn't support locales that have digits other than 0-9. For example, if the current locale is bengali, then the number 123456789 would come out as "?????????". And that's just the digits, nevermind what the digit grouping would be. But the same problem happens for numbers in the Invariant locale, which formats numbers as "123,456,789", which SQL Server won't accept. Is there a culture that matches what SQL Server accepts for numeric values? Or will i have to create some custom "sql server" culture, generating rules for that culture myself from lower level formatting routines? If i was in .NET (which i'm not), i could peruse the Standard Numeric Format strings. Of the format codes available in .NET: c (Currency): $123.46 d (Decimal): 1234 e (Exponentional): 1.052033E+003 f (Fixed Point): 1234.57 g (General): 123.456 n (Number): 1,234.57 p (Percent): 100.00 % r (Round Trip): 123456789.12345678 x (Hexadecimal): FF Only 6 accept all numeric types: c (Currency): $123.46 d (Decimal): 1234 e (Exponentional): 1.052033E+003 f (Fixed Point): 1234.57 g (General): 123.456 n (Number): 1,234.57 p (Percent): 100.00 % r (Round Trip): 123456789.12345678 x (Hexadecimal): FF And of those only 2 generate string representations, in the en-US locale anyway, that would be accepted by SQL Server: c (Currency): $123.46 d (Decimal): 1234 e (Exponentional): 1.052033E+003 f (Fixed Point): 1234.57 g (General): 123.456 n (Number): 1,234.57 p (Percent): 100.00 % r (Round Trip): 123456789.12345678 x (Hexadecimal): FF Of the remaining two, fixed is dependant on the locale's digits, rather than the number being used, leaving General g format: c (Currency): $123.46 d (Decimal): 1234 e (Exponentional): 1.052033E+003 f (Fixed Point): 1234.57 g (General): 123.456 n (Number): 1,234.57 p (Percent): 100.00 % r (Round Trip): 123456789.12345678 x (Hexadecimal): FF And i can't even say for certain that the g format won't add digit groupings (e.g. 1,234). Is there a locale that formats numbers in the way SQL Server expects? Is there a .NET format code? A java format code? A Delphi format code? A VB format code? A stdio format code? latin-numeral-digits

• ImageButton OnClick Event not firing

  - by webnoob

  Hi All, I am really confused about this one. I have some code that runs fine on my development server but I am now trying to get the site working on the sales guys new laptop. None of the image buttons on the website seem to be working for him (they just redirect me back to the websites homepage) whereas they used to on his previous machine. The only difference between each machine is that his old one was Vista and the new one is Windows 7. Has anyone come accross this issue? Some code: The form: <div class="form_text"></div> <div class="form_box_link"> <asp:ImageButton id="LoginSubmitButton" onClick="FLoginWebService" ImageURL="~/Images/login.png" runat="server" /> </div> The code behind (delphi): procedure TMemberLogin.FLoginWebService(Sender: TObject; e: System.EventArgs); begin //Code Removed but using OutputDebugString shows nothing is being done in here end; As mentioned, this works everywhere else except on his windows 7 machine.

• Properly design a code editor application

  - by Hemaulo

  I'm working on personal project which is basically a code editor. Imagine standard File menu with menu items New, Open, Save, Save As, Save All, Close, Close All. I'm stuck with proper design. Currently I have: A Document class which represents a document - code editing control, respective tab in tab bar and various properties such as Caption, Filename, IsModified etc. A Documents class which represents all open documents. Contains methods like New, Open(FileName), ... The problem is that I can't figure out which class / menu command is responsible for which tasks. For example, with File-New menu command is simple - call Documents.New and that's it. But what for File-Open? The Documents.Open method expects filename as a parameter. So before calling this method I need to open an file selection dialog, let user select files and for each file call Documents.Open(FileName). Where is best place for this supporting code, in menu command, rewrite Documents.Open and put it there? The same with Save actions. Which is responsible for saving? Is it Documents class which uses Document.Editor.SaveToFile(FileName) or better create Save method in Document class? Somewhere in the middle also need to ask user if he wants to save current document... I'm stuck. Any ideas? Edited: The programming language is Delphi.

• How to upload files and store them in a server local path when MS SQL SERVER allows remote connectio

  - by user193655

  I am developing a win32 windows application with Delphi and MS SQL Server. it works fine in LAN but I am trying to add the support for SQL Server remote connections (= working with a DB that can be accessed with an external IP, as described in this article: http://support.microsoft.com/default.aspx?scid=kb;EN-US;914277). Basically I have a Table in DB where I keep the DocumentID, the document description and the Document path (like \FILESERVER\MyApplicationDocuments\45.zip). Of course \FILESERVER is a local (LAN) path for the server but not for the client (as I am now trying to add the support for remote connections). So I need a way to access \FILESERVER even if of course I cannot see it in LAN. I found the following T-SQL code snippet that is perfect for the "download trick": SELECT BulkColumn as MyFile FROM OPENROWSET(BULK '\FILESERVER\MyApplicationDocuments\45.zip' , SINGLE_BLOB) AS X With the code above I can download a file on the client. But how to upload it? I need an "Uppload trick" to be able to insert new files, but also to delete or replace existing files. Can anyone suggest? If a trick is not available could you suggest an alternative? Like an extended stored procedure or calling some .net assembly from the server.

• Is C++ (one of) the best language to learn at first

  - by AlexV

  C++ is one of the most used programming language in the world since like 25+ years. My first job as programmer was in C++ and I coded in C++ everyday for nearly 4 years. Now I do mostly PHP, but I will forever cherish this C++ background. C++ has helped me understand many "under the hood" features/behaviors/restrictions of many other (and different) programming languages like PHP and Delphi. I'm a full time programmer for 6+ years now and since I have a quite varied programming background I often get questions by "newbies" as where to start to become a "good" programmer. I think C++ is one of the best language to start with because it gives you a real usefull experience that will last and will teach you how things work under the hood. It's not the easier one to learn for a newbie, but in my opinion it's one that will reward in the long term. I would like to know your opinion on this matter to add to my arguments when I guide "newbies". After this introduction, here's my question : Is C++ (one of) the best language to learn at first for you. Since it's subjective, I've marked this question as community wiki. EDIT: This question is not about why Java (or C# or any other language) is better than C++ to start with, it's about what's make C++ a good choice or not a good choice to learn as one of your firsts languages. For example, for me C++ made me understand how the memory works. Now today in many languages everything is managed by the garbadge collector and some people don't even know that. I'm glad I know how it works underneath and I think it can help you to write better code.

• Why are (almost) all the on-line games written in ActionScript (Flash) not Java?

  - by MasterPeter

  I absolutely love good defender games (e.g. Gemcraft, Protector: reclaiming the throne) as they can be intellectually quite challenging; it's like playing chess but a little less thinking a bit more action. Sadly, there are not that many good ones out there and I thought I would create one myself and share it with the rest of the world by making it available on-line. I have never worked with ActionScript but when it comes to on-line games, this is the main choice. I have tried to find a decent 2D game in the form of a Java applet but to no avail. Why is this so? I could write the game, most comfortably, in Delphi for Win32 but then people would need to download the executable, which could deter some form downloading it, and also it would only work on Windows. I am also familiar with Java, having worked with Java for the last four years or so. Although I don't have much experience with games programming. Should I note be deterred by the fact that all online games are written for in Flash and create my defender game as a Java applet, or should I consider learning ActionScript and games development for the ActionScript Virtual Machine (AS3 looks very much like Java... but still, it's an entirely new technology to me and I might never use it professionally.) Could you, please, just answer the the question in the title? Why Flash, not Java applets? Is it only 'politics'?

• Special Characters in JS, how to use "/" character

  - by user1461222

  I've vbulletin 4.2.0 i added an special button to it's editor with this article; http://www.vbulletinguru.com/2012/add-a-new-toolbar-button-to-ckeditor-tutorial/ The thing i want to do is add an syntax highlighter code with this button. When i use below code it's working fine; CKEDITOR.plugins.add( 'YourPluginName', { init: function( editor ) { editor.addCommand( 'SayHello', { exec : function( editor ) { editor.insertHtml( "Hello from my plugin" ); } }); editor.ui.addButton( 'YourPluginName', { label: 'My Button Tooltip', command: 'SayHello', icon: this.path + 'YourPluginImage.png' } ); } } ); so i changed this code to this, because i wannt to add specific text like below; CKEDITOR.plugins.add( 'DKODU', { init: function( editor ) { editor.addCommand( 'SayHello', { exec : function( editor ) { editor.insertHtml( '[kod=delphi][/kod]' ); } }); editor.ui.addButton( 'DKODU', { label: 'My Button Tooltip', command: 'SayHello', icon: this.path + 'star.png' } ); } } ); after update the code when i press the button nothings happen, i checked with google and this site but i couldn't figure it out i think i made mistake with some special characters but i couldn't find what's the problem. If i made some mistakes when i publish this question forgive me and also forgive me for my bad english, thanks.

• object / class methods serialized as well?

  - by Mat90

  I know that data members are saved to disk but I was wondering whether object's/class' methods are saved in binary format as well? Because I found some contradictionary info, for example: Ivor Horton: "Class objects contain function members as well as data members, and all the members, both data and functions, have access specifiers; therefore, to record objects in an external file, the information written to the file must contain complete specifications of all the class structures involved." and: Are methods also serialized along with the data members in .NET? Thus: are method's assembly instructions (opcodes and operands) stored to disk as well? Just like a precompiled LIB or DLL? During the DOS ages I used assembly so now and then. As far as I remember from Delphi and the following site (answer by dan04): Are methods also serialized along with the data members in .NET? sizeof(<OBJECT or CLASS>) will give the size of all data members together (no methods/procedures). Also a nice C example is given there with data and members declared in one class/struct but at runtime these methods are separate procedures acting on a struct of data. However, I think that later class/object implementations like Pascal's VMT may be different in memory.

• How can I add SOAP Headers to a WSDL generated Borland C++ Builder 6 application.

  - by MJG

  Using a WSDL that requires a SOAP HEADER for Authentication (fragment below) code that gets generated when creating a web service client via the "WSDL Importer" has no concept of the Authentication Headers and there are no examples in BCB6 C++ Examples/WebServices directories that show how, and nothing on Web that I can find. Anyone with BCB6 C++ (not Delphi) have an example of adding SOAP Headers to a TRemotable subclass? <s:element name="AuthenticationHeader" type="tns:AuthenticationHeader"/> <s:complexType name="AuthenticationHeader"> <s:complexContent mixed="false"> <s:extension base="tns:UserAuthHeader"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="Function" type="s:string"/> <s:element minOccurs="1" maxOccurs="1" name="TimeOutMilliSec" type="s:int"/> </s:sequence> </s:extension> </s:complexContent> </s:complexType> <s:complexType name="UserAuthHeader"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="Username" type="s:string"/> <s:element minOccurs="0" maxOccurs="1" name="Password" type="s:string"/> </s:sequence> <s:anyAttribute/> </s:complexType>

• What programming language do you wish would quietly retire? [closed]

  - by Gregory Higley

  This is the inverse of the "What programming language do you wish would catch on?" question. I was a Delphi programmer for many years, and I still appreciate its power, but I dislike verbose programming languages. So I would love to see Pascal put out to pasture. The same goes for BASIC in any form, despite the fact that it's the language I cut my teeth on. When I look at cathedrals of beauty like Haskell and REBOL, BASIC just makes me cringe. (VB.NET is tolerable, but barely. It has a few nice language features I'd like to see moved to C#.) My dislike of Pascal and VB.NET is subjective. They are powerful languages, but I dislike their syntax esthetically. Try to explain your reasoning, if you can, even if it's just "I don't like its syntax." This question is not meant to be a flame war, argumentative, or hateful. It's meant to be a straightforward, honest discussion of programmers' dislikes.

• Visual Studio build fails: unable to copy exe-file from obj\debug to bin\debug

  - by Nailuj

  This is a question asked before, both here on Stack Overflow and other places, but none of the suggestions I've found this far has helped me, so I just have to try asking a new question. Scenario: I have a simple Windows Forms application (C#, .NET 4.0, Visual Studio 2010). It has a couple of base forms that most other forms inherit from, it uses Entity Framework (and POCO classes) for database access. Nothing fancy, no multi-threading or anything. Problem: All was fine for a while. Then, all out of the blue, Visual Studio failed to build when I was about to launch the application. I got the warning "Unable to delete file '...bin\Debug\[ProjectName].exe'. Access to the path '...bin\Debug\[ProjectName].exe' is denied." and the error "Unable to copy file 'obj\x86\Debug\[ProjectName].exe' to 'bin\Debug\[ProjectName].exe'. The process cannot access the file 'bin\Debug\[ProjectName].exe' because it is being used by another process." (I get both the warning and the error when running Rebuild, but only the error when running Build - don't think that is relevant?) I understand perfectly fine what the warning and error message says: Visual Studio is obviously trying to overwrite the exe-file while it the same time has a lock on it for some reason. However, this doesn't help me find a solution to the problem... The only thing I've found working is to shut down Visual Studio and start it again. Building and launching then works, untill I make a change in some of the forms, then I have the same problem again and have to restart... Quite frustrating! As I mentioned above, this seems to be a known problem, so there are lots of suggested solutions. I'll just list what I've already tried here, so people know what to skip: Creating a new clean solution and just copy the files from the old solution. Adding the following to the following to the project's pre-build event: if exist "$(TargetPath).locked" del "$(TargetPath).locked"   if not exist "$(TargetPath).locked" if exist "$(TargetPath)" move "$(TargetPath)" "$(TargetPath).locked" Adding the following to the project properties (.csproj file): <GenerateResourceNeverLockTypeAssembliestrue</GenerateResourceNeverLockTypeAssemblies However, none of them worked for me, so you can probably see why I'm starting to get a bit frustrated. I don't know where else to look, so I hope somebody has something to give me! Is this a bug in VS, and if so is there a patch? Or has I done something wrong, do I have a circular reference or similar, and if so how could I find out? Any suggestions are highly appreciated :)

• Expose UserControl property to XAML

  - by Jared

  WPF controls have certain properties (UserControl.Resources, UserControl.CommandBindings) that can have items added to them from the XAML of a user control declaration. Example: <UserControl ... > <UserControl.CommandBindings> ... </UserControl.CommandBindings> <UserControl.Resources> ... </UserControl.Resources> </UserControl> I have a new list property defined in my user control: public partial class ArchetypeControl : UserControl { ... public List<Object> UICommands { get; set; } I want to add items to this list like I can with resources and CommandBindings, but when I do this: <c:ArchetypeControl.UICommands> </c:ArchetypeControl.UICommands> I get the error "Error 4 The attachable property 'UICommands' was not found in type 'ArchetypeControl'. " Suggestions? - Given the comments, I've created a test control to show the entire code and reproduce the problem. I'm using visual studio 2010. <UserControl x:Class="ArchetypesUI.TestControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:c="clr-namespace:ArchetypesUI" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <c:TestControl.TestObject> </c:TestControl.TestObject> <Grid> </Grid> </UserControl> - namespace ArchetypesUI { /// <summary> /// Interaction logic for TestControl.xaml /// </summary> public partial class TestControl : UserControl { public Object TestObject { get; set; } public TestControl() { InitializeComponent(); } } } Now the error I get is "Error 2 The attached property 'TestControl.TestObject' is not defined on 'UserControl' or one of its base classes."

• Apache, Nginx, WSGI, django cookies get lost.

  - by Jack M.

  I'm running into a problem trying to get a Django application running in my staging environment. I'm running nginx as a reverse proxy with Apache 2.2/mod_wsgi as the target, and my Django app behind that. The problem is that the cookies are getting lost somewhere between nginx and Apache. My nginx.conf (ripped out a few locations to keep it small): http { gzip on; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass_header Set-Cookie; upstream django { server 127.0.0.1:8080; } server { listen 80; server_name encendio.iigins.com; location / { proxy_pass http://django; } } } My Apache vhosts file: <VirtualHost *:8080> ServerName encendio.test.com ServerAdmin [email protected] DocumentRoot "/usr/local/www/apache22/data" WSGIScriptAlias / /usr/local/www/apache22/data/sasquatch/wsgi_handler.py </VirtualHost> If I directly to http://encendio.test.com:8080/ the cookies work and I can log into the admin area. If I log into http://encendio.test.com/, the admin area tells me my browser isn't using cookies. Now things get kind of weird. I went so far as to look at the environ being passed into my wsgi_handler.py: _application = django.core.handlers.wsgi.WSGIHandler() def application(environ, start_response): print >> sys.stderr, environ.get('HTTP_COOKIE', "No Cookie") return _application(environ, start_response) It shows the cookie existing in the environment: [Mon Mar 22 12:15:50 2010] [error] csrftoken=9f2569elkj67984242f0e7a6dea0b791; sessionid=4e5432hjkds8603f26d5ffa02b10cd27 And this cookie matches up with what I see in nginx's log if I plug in $http_cookie on the end of the log. So Apache is getting the cookie in some form, but it's not ending up where Django can see it. I'm at my wit's end for why this isn't working, so any help is greatly appreciated. Ninja Edit: I forgot to mention that Firefox is seeing the cookies. The oddity is that every time I attempt to log in, I get a new sessionid.

• Setting a Visual State from a data bound enum in WPF

  - by firoso

  Hey all, I've got a scenario where I want to switch the visiblity of 4 different content controls. The visual states I have set opacity, and collapsed based on each given state (See code.) What I'd like to do is have the visual state bound to a property of my View Model of type Enum. I tried using DataStateBehavior, but it requires true/false, which doesn't work for me. So I tried DataStateSwitchBehavior, which seems to be totally broken for WPF4 from what I could tell. Is there a better way to be doing this? I'm really open to different approaches if need be, but I'd really like to keep this enum in the equation. Edit: The code shouldn't be too important, I just need to know if there's a well known solution to this problem. <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

• Removing expired certificates from LDS (new ver of ADAM)

  - by jonthebrewer

  Hi all. This is my situation: We are in the process of replacing a certificate store currently hosted on Sun's iPlanet with Microsoft's Lightweight Directory Services (new version of ADAM with Server 2008). These certificates have been imported into LDS into an application partition (say o=myorg, C=AU). Under this structure I have around 40,000 OU's each one representing a customer under each customers OU are one or more user (iNetOrg) objects (around 60,000 in all). In each user are one or more certificates in the UserCertificate attribute. A combination of in-house written application code and proprietory PKI code reads and publishes these certficates to validate financial transactions. As the LDAP path of the certificates is stored within the customer certificates (and within the application code) and there is zero appetite for changing any of the code, I have had to pick up the iPlanet directory as a whole and dump it in LDS in the same structure. (I will not be using or hosting a Microsoft CA, just implementing an LDAP compliant directory to host these certificates) We have fully tested the application using the data in LDS and everything works fine - here is my dilema and question (finally, phew!) There was no process put in place for removing revoked or expired certificates, consequently the vast majority of the data is completely useless, the system has been running for about 8 years! I have done a quick analysis and I estimate that at least 80% of the data is no longer valid. As I am taking on responsibility for managing the directory I would like to start with a clean directory. Does anyone have any idea how I can cleanup these expired certificates. I am not a highly experienced scripter but have some background in VB. I have been researching the use of CAPICOM and have a feeling this may be able to be used but in exactly what way I am not sure?? I would prefer to write a script that I could specify an expiration date (say any certs that expired prior to 2010) then run against the LDS paritition. This way I can reuse the script periodically to cleanup the directory (as mentioned above - I have no way to adjust the applications that are writing the certs, this is with a third party). Another, less attractive, alternative is to massage the LDIF file (2.7 million lines!) to rip the certs out prior to the import Any help and advice MUCH appreciated. Cheers Jon

• MSBuild: Add additional files to compile without altering the project file

  - by Craig Norton

  After looking around I can't find a simple answer to this problem. I am trying to create an MSBuild file to allow me to easily use SpecFlow and NUnit within Visual Studio 2010 express. The file below is not complete this is just a proof of concept and it needs to be made more generic. <Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <BuildDependsOn> BuildSolution; SpecFlow; BuildProject; NUnit; </BuildDependsOn> </PropertyGroup> <PropertyGroup> <Solution>C:\Users\Craig\Documents\My Dropbox\Cells\Cells.sln</Solution> <CSProject>C:\Users\Craig\Documents\My Dropbox\Cells\Configuration\Configuration.csproj</CSProject> <DLL>C:\Users\Craig\Documents\My Dropbox\Cells\Configuration\bin\Debug\Configuration.dll</DLL> </PropertyGroup> <Target Name="Build" DependsOnTargets="$(BuildDependsOn)"> </Target> <Target Name="BuildSolution"> <MSBuild Projects="$(Solution)" Properties="Configuration=Debug" /> </Target> <Target Name="SpecFlow"> <Exec Command="SpecFlow generateall $(CSProject)" /> </Target> <Target Name="BuildProject"> <MSBuild Projects="$(CSProject)" Properties="Configuration=Debug" /> </Target> <Target Name="NUnit"> <Exec Command='NUnit /run "$(DLL)"' /> </Target> The SpecFlow Task looks in the .csproj file and creates a SpecFlowFeature1.feature.cs. I need to include this file when building the .csproj so that NUnit can use it. I know I could modify (either directly or on a copy) the .csproj file to include the generated file but I'd prefer to avoid this. My question is: Is there a way to use the MSBuild Task to build the project file and tell it to include an additional file to include in the build? Thank you.
