• How can I sign a Windows Mobile application for internal use?

  - by AR

  I'm developing a Windows Mobile application for internal company use, using the Windows Mobile 6 Professional SDK. Same old story: I've developed and tested on the emulator and all is well, but as soon as I deploy to advice I get an UnauthorizedAccessException when writing files or creating directories. I'm aware that an application installed to a device needs to be signed but I'm running into roadblocks at every turn: Using the project properties 'Devices' window I select 'Sign the project output with this certificate, and choose one of the sample certificates from the SDK. This results in a build error: "The signer's certificate is not valid for signing" when running SignTool. If I try to run SignTool.exe from the commandline, I get an error telling me to run SignTool.exe from a location in the system's PATH. I can't use the 'Signing' tab in the Project Properties to create a test certificate - this is greyed out (presumably for WinMobile projects?). If at all possible, I would like to avoid having to go through Versign or the like to get a Mobile2Market certificate. If I have to go this route for a final version that's fine, but I need to at least be able to test the app on real devices. Any advice would be most welcome!

• Visual Studio crashes when I add a .settings file in a C++ Windows form application

  - by Ant

  I'm trying to add a .settings file in a windows form application by adding a (whatever) file in the project and have it named smthng.settings. Right after it is created, it crashes (if I look into the project's directory the file is there, but it's not "in" the project). Am I doing it wrong or could it be that the problem lies elsewhere? Edit: It seems that it's the settings designer that crashes. Partially Solved:If I add a (whatever).config file, then rename it to .settings and change it's file type to C/C++ Code (don't ask how I figured this out..) then I can add to it settings, but if I do add something that has any connection to the form then automatically a (whatever).config with thew same name spawns (which is identical to the (whatever).setting even if change one of them) and at the stdafx.cpp a #include '(whatever).h' appears, which is a problem, because there is not such a header. (if I erase it or just create a blank (whatever).h it doesn't work. Apparently I have to somehow connect all the data in the (w/e).settings to (w/e).h as well or maybe something else) Anyone had this problem before? Anyone has any ideas?

• Errors with redefinitions after upgrade to XCode 3.2.3

  - by CA Bearsfan

  I recently upgraded to Snow Leopard and Xcode 3.2.5 so I could test on my iPod Touch and iPhone and ran into some problems with the project I was working on. First it couldn't find a Base SDK, then my old frameworks weren't hooking up correctly. Finally after setting the Project Format to Xcode 3.1 compatible (3.2 also worked) and the Base SDK for all configurations to iOS 4.2, then setting my iOS deployment target to iOS 3.0 I was able to get the system to find a Base SDK and attempt a build. That's when the frameworks didn't want to cooperate. 4/6 I'm using displayed in red, so I re routed the path to the iPhone simulator 4.2 platform which worked perfectly. I was able to build my project, no errors or warnings and my app worked fine. I went to work last night thinking I had fixed the problem. This morning I fired up the laptop and went to build my code base and now have 1142 errors all of which have to do with code I haven't written deemed as being redefined. Suggestions? The following is just a small sample of the error list (obviously don't need to see all 1142) //Frameworks/Foundation.framework/Headers/NSZone.h:48: error: redefinition of 'NSMakeCollectable' /Frameworks/Foundation.framework/Headers/NSObject.h:65: error: duplicate interface declaration for class 'NSObject' /Frameworks/Foundation.framework/Headers/NSObject.h:67: error: redefinition of 'struct NSObject'

• StrcutureMap Wiring - Sanity Check Please

  - by Steve Ward

  Hi - Im new to IOC and StructureMap and have an n-level application and am looking at how to setup the wirings (ForRequestedType ...) and just want to check with people with more experience that this is the best way of doing it! I dont want my UI application object to reference my persistence layer directly so am not able to wire everything up in this UI project. I now have it working by defining a Registry class in each project which wires up the types in the project as needed. The layer above registers its types and also calls the assembly below and looks for registries so that all types are registered throught the hierrachy. E.g. I have UI, Service, Domain, and Persistence libraries. In my service layer the registry looks like Scan(x => { x.Assembly("MyPersistenceProject"); x.LookForRegistries(); }); ForRequestedType<IService>().TheDefault.Is.OfConcreteType<MyService>(); Is this a recommended way of doing this in a setup such as this? Are there better ways and what are the advantages / disadvantages of these approaches in this case?

• Flex Modules vs RSL

  - by nil

  Hi, I'm a little bit confused about when is better to use Flex Modules or RSL libriaries (in Flex 3.5). My goal is split my project in several unit projects, so I can test and work separately. Let's assume I have a Customer app and Vendor app. I also have a front-end panel with two buttons. Each button launches Customer app or Vendor app. These applications make different things. They share some .as functions and common components, too. I understand that if I make a main project (for user login and to show a first panel) and two modules (customer, vendor) I must have all that components in my Eclipse project, isn't it? Instead of doing modules, should I create SWC for Vendor and other for Customer app and call from main app by using RSL? So, which option is more suitable? What do you advise me? Which are the trade-offs of each option? On the other side, this flex application is integrated with Java through Blaze and ibatis for persistence managment, and hold by a web apache server. I considered also to create independent war files to keep this indpendence, but I thought this do not optimize flex code. I'm right? Thank you. Nil

• Visual Studio: What approach do you use to 'template' plumbing for similiar projects?

  - by Sosh

  When building ASP.NET projects there is a certain amount of boilerplate, or plumbing that needs to be done, which is often identical across projects. This is especially the case with MVC and ALT.NET approaches. [I'm thinking of things such as: IoC, ORM, Solution structure (projects), Session Management, User Management, I18n etc.] I would like to know what approach you find best for 'reusing' this plumbing accross projects? Have a 'master solution' which you duplicate and rename somehow? (I'm using a this to a degree at the moment, but it's fairly messy. Would be interested how people do this 'better') Mainly rely on Shared Library projects? (I find this appropriate for some things, but too restrictive for things that have to be customised) Code generation tools, such as T4? (Similar to the approach used by SharpArchitecture - have not tried this myself) Something else? Thanks for sharing your experiences!

• Accurev SCM

  - by FlySwat

  Does anyone use Accurev for Source Control Management? We are switching (eventually) from StarTeam to Accurev. My initial impression is that the GUI tool is severely lacking, however the underlying engine, and the branches as streams concept is incredible. The biggest difficulty we are facing is assessing our own DIY tools that interfaced with starteam, and either replacing them with DIY new tools, or finding and purchasing appropriate replacements. Additionally, is anyone using the AccuWork component for Issue management? Starteam had a very nice change request system, and AccuWork does not come close to matching it. We are evaluating either using Accuwork, or buying a 3rd party package such as JIRA. Opinions?

• AnkhSVN: Cannot checkout Subsolution due to existing "versioned" folder

  - by lostiniceland

  Hello Everyone I am using Subversion since quite some time for Java-Development and I have setup a repository on my local NAS. Since I have a MSDN subscription via my company I recently installed Visual Studio 2010 to do a small project with .NET. According to some "best-practices" my project folder looks like the following. MySolution main.sln Services services.sln Service A files Service A Test files View projectfiles Persistence persistence.sln PersistenceXml files PersistenceXml Test files PersistenceDB files PersistenceDB Test files The idea is, that the main.sln only contains the projects for the application, meaning no test projects. The subsolutions, contain the project(s) and their corresponding testprojects. I was able to put all those projects under versioncontrol with AnkhSVN, so I have the same structure there in my trunk. Commiting changes was also no problem. Now I would like to check the this out on another machine. I was able to check out the main.sln which downloaded everything that was inside this solution. It skipped the services.sln, persistence.sln and all the test-projects. Until now everything is fine. Now, here comes the problem: when I am tryting to check out the subsolution (eg. services.sln) I get an error, I think it was UnsupportedOperation. I guess this happens because ankhsvn is tryting to download the folder Service A again and create ist hidden .svn folder which is already present. The only workaround I can think of by now is installing Tortoise SVN and check out the whole thing at once. It would be nicer though to have everything from within VS. Does anyone know how I can solve this? Is another client the only solution?

• Get an array of structures from native dll to c# application

  - by PaulH

  I have a C# .NET 2.0 CF project where I need to invoke a method in a native C++ DLL. This native method returns an array of type TableEntry. At the time the native method is called, I do not know how large the array will be. How can I get the table from the native DLL to the C# project? Below is effectively what I have now. // in C# .NET 2.0 CF project [StructLayout(LayoutKind.Sequential)] public struct TableEntry { [MarshalAs(UnmanagedType.LPWStr)] public string description; public int item; public int another_item; public IntPtr some_data; } [DllImport("MyDll.dll", CallingConvention = CallingConvention.Winapi, CharSet = CharSet.Auto)] public static extern bool GetTable(ref TableEntry[] table); SomeFunction() { TableEntry[] table = null; bool success = GetTable( ref table ); // at this point, the table is empty } // In Native C++ DLL std::vector< TABLE_ENTRY > global_dll_table; extern "C" __declspec(dllexport) bool GetTable( TABLE_ENTRY* table ) { table = &global_dll_table.front(); return true; } Thanks, PaulH

• How are developers using source control, I am trying to find the most efficient way to do source con

  - by RJ

  I work in a group of 4 .Net developers. We rarely work on the same project at the same time but it does happen from time to time.We use TFS for source control. My most recent example is a project I just placed into production last night that included 2 WCF services and a web application front end. I worked out of a branch called "prod" because the application is brand new and has never seen the light of day. Now that the project is live, I need to branch off the prod branch for features, bugs, etc... So what is the best way to do this? Do I simple create a new branch and sort of archive the old branch and never use it again? Do I branch off and then merge my branch changes back into the prod branch when I want to deploy to production? And what about the file and assembly version. They are currently at 1.0.0.0. When do they change and why? If I fix a small bug, which number changes if any? If I add a feature, which number changes if any? What I am looking for is what you have found to be the best way to efficiently manage source control. Most places I have worked always seem to bang heads with the source control system in on way or another and I would just like to find out what you have found that works the best.

• How do you prevent Git from printing 'remote:' on each line of the output of a post-recieve hook?

• ParseKit.framework won't work, Foundation.h not found

  - by Jeremy

  I'm really stumped trying to get the ParseKit.framework (this) to work in general, not even bothering to implement it till it runs the demo app that comes with it. What happens is the compiler can't locate < Foundation/Foundation.h or something, which I thought the header was in the linked framework. Exact error: "Lexical or Preprocessor Issue: 'Foundation/Foundation.h' file not found." Here's the code, just from the ParseKit_Prefix.pch: // // Prefix header for all source files of the 'ParseKit' target in the 'ParseKit' project. //#ifdef __OBJC__ #import <Foundation/Foundation.h> #endif Nothing unusual about it, did I mess up the file paths some how? I've reinstalled Xcode, re-downloaded the ParseKit, and nothing is helping. The suggestions here did nothing and it's not this. When I make a new project or use a different project and load the Foundation.framework and #import the header it works just fine. If I unlink the framework I can't find it to re-link again. Has anyone else had this kind of problem? Did I download it wrong somewhere? I have a very difficult time finding where exactly the Xcode UI links stuff, apple must get a kick out of frustrating people, so if anyone has anything they can think of please give me some feedback, I'm horribly confused right now. Thanks,

• How to debug an external library (OpenCV) in Visual C++?

  - by neuviemeporte

  I am developing a project in VC++2008. The project uses the OpenCV library (but I guess this applies to any other library). I am working with the Debug configuration, the linker properties include the debug versions of the library .lib's as additional dependencies. In VC++ Directories under Tools|Options i set up the include directory, the .lib directory, the source directories for the library as well. I get an error while calling one of the functions from the library and I'd like to see exactly what that function is doing. The line that produces the error is: double error = cvStereoCalibrate(&calObjPointsM, &img1PointsM, &img2PointsM, &pointCountsM, &cam1M, &dist1M, &cam2M, &dist2M, imgSize, &rotM, &transM, NULL, NULL, cvTermCriteria(CV_TERMCRIT_ITER + CV_TERMCRIT_EPS, 100, 1e-5)); I set up a breakpoint at this line to see how the cvStereoCalibrate() function fails. Unfortunately the debugger won't show the source code for this function when I hit "Step into". It skips immediately to the cvTermCriteria() (which is a simple inline, macro-kinda function) and show its contents. Is there anything else I need to do to be able to enter the external library functions in the debugger? EDIT: I think the cvTermCriteria() function shows in the debugger, because it's defined in a header file, therefore immediately accesible to the project.

• Is the REST support in Spring 3's MVC Framework production quality yet?

  - by glenjohnson

  Hi all, Since Spring 3 was released in December last year, I have been trying out the new REST features in the MVC framework for a small commercial project involving implementing a few RESTful Web Services which consume XML and return XML views using JiBX. I plan to use either Hibernate or JDBC Templates for the data persistence. As a Spring 2.0 developer, I have found Spring 3's (and 2.5's) new annotations way of doing things quite a paradigm shift and have personally found some of the new MVC annotation features difficult to get up to speed with for non-trivial applications - as such, I am often having to dig for information in forums and blogs that is not apparent from going through the reference guide or from the various Spring 3 REST examples on the web. For deadline-driven production quality and mission critical applications implementing a RESTful architecture, should I be holding off from Spring 3 and rather be using mature JSR 311 (JAX-RS) compliant frameworks like RESTlet or Jersey for the REST layer of my code (together with Spring 2 / 2.5 to tie things together)? I had no problems using RESTlet 1.x in a previous project and it was quite easy to get up to speed with (no magic tricks behind the scenes), but when starting my current project it initially looked like the new REST stuff in Spring 3's MVC Framework would make life easier. Do any of you out there have any advice to give on this? Does anyone know of any commercial / production-quality projects using, or having successfully delivered with, the new REST stuff in Spring 3's MVC Framework. Many thanks Glen

• Visual studio erroneous errors when building a website?

  - by Curtis White

  Visual Studio 2008 shows a lot of erroneous errors when building a website (not a web project) in the errors list. These errors are usually corrected (removed) when I rebuild the site a couple times but they cost me wasted time. Is there anyway to hide the erroneous errors? Update: I've decided to look into this to see if I could reproduce it. This is the exact behavior I am seeing, using the website model, I type some invalid syntax on a page. The errors list fills up with errors. I correct the error and the errors list does not update. I build the project and the errors list still shows the errors but the build shows as build completed. I build the project a second time and the errors list is cleared. My question is there anyway to make the errors list clear on the first build? I thought it might have something to do with page build vs website build but it seems to make no difference. I am not using any third party dlls on this website.

• Git: changes not reflecting on other checkouts - huh?

  - by Chad Johnson

  Okay, so, I have my branches (git branch -a): * chat master remotes/origin/HEAD -> origin/master remotes/origin/chat I make changes (still with the 'chat' branch checkout out), commit, and push. I go to my server, on which I have a clone of the repository, and I do a fetch: git getch then I switch to the chat branch: git checkout --track -b chat origin/chat and I event do a pull, just to make sure everything is up to date: git pull and my changes from my other computer are NOT. THERE. What the heck am I doing wrong? If I had hair, I would have pulled it out. Thankfully I am bald. When I try a 'git commit' again, I get this # On branch chat # Changed but not updated: # (use "git add/rm <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: app/controllers/chat_controller.rb # modified: app/views/dashboard/index.html.erb # modified: app/views/dashboard/layout.js.erb # modified: app/views/layouts/dashboard.html.erb # deleted: app/views/project/.tmp_edit.html.erb.55742~ # deleted: app/views/project/.tmp_edit.html.erb.83482~ # modified: public/stylesheets/dashboard/layout.css # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # .loadpath # .project # config/database.yml # config/environments/development.yml # config/environments/production.yml # config/environments/test.yml # log/ no changes added to commit (use "git add" and/or "git commit -a")

• What is the process involved in viewing a webservice in a browser from within visual studio?

  - by Sam Holder

  I have created a new VS2008 ASP.Net Web service project, with the default name WebService1. If I right click on the Service1.asmx file and select 'View in Browser' what are the processes that go on to make this happen? I am asking because I have a situation where when I run this from a visual studio project started in our development shell (which sets up a common build environment) I cannot get the web service to show up in the browser. It starts the asp.net development server and creates a single file: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\c43ddc22\268ae91b\hash\hash.web but when I start it from a stand alone project i get a whole slew of files in here: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\edad4eee\d198cf0e\App_Web_defaultwsdlhelpgenerator.aspx.cdcab7d2.vicgkf94.dll C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\edad4eee\d198cf0e\service1.asmx.cdcab7d2.compiled etc etc I am trying to debug this but not really getting anywhere. i have inspected the output from VS but the only option I get is for the build output, which is basic and doesn't really contain any information that is useful. I have tried running both versions with DebugView running but no output there either. I would like to know if there are any log files I could look at, or if anyone has any suggestions on how I might be able to debug what is going wrong here? For completeness the output I get when it doesn't work is: Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not create type 'WebService1.Service1'.

• Programming exercises in Java inheritance for intern

  - by Tenner

  I work for a small software development team, working primarily in Java, for a very large company. Our new intern showed up sight-unseen (not uncommon in my company). He has some C++ experience but no Java. Worse, he's never worked with inheritance in C++. Our code has a great deal of abstraction and a heavy reliance on inheritance. We need to get him up to speed as quickly as possible. Of course the rest of the team is busy, and so we can't take the time out of our day to teach a one-student 200-level CS course. Instead, I'd like to give him an actual programming project to work on which highlights how classes, interfaces, method overrides, etc. work. I've had him look at Project Euler, but most of the solutions end up being procedural, and not object-oriented programs. Do any of you have any somewhat-straightforward (and relatively quick) projects which you would give to an intern in this situation? Or, any recent (or current) students have a school project they'd be willing to share? Anyone else had this experience?

• Concurrent Programming:Should I write a sequential program first, then add thread safety?

  - by evthim

  I'm working on a project where we have to create a number of threads(actual number will be inputted in by testers (TA's)). I'm having trouble not only with the programming but also with the design, I can't wrap my head around all of the threads that will be invoked and where I might cause errors. The project is due soon so I don't want to waste time on this if it'll actually set me back, but I was wondering if I should write the program like only one thread will be running and everything should be sequential and then later go back and try to add the thread safety parts of the code? Would that take twice the original amount of time? Project Description: Note:I'm going to be as vague as possible so I don't violate any honor codes, sorry :( your program should accept n number of objectA threads, m number of objectB threads, and r number of objectC objectB threads interact with code in objectA. objectA threads interact with code in objectB and objectC objectB and objectC don't directly interact, but do so indirectly through objectA -ex: objectB needs something from objectA. objectA gets the result for that something by calling objectC my confusion stems mostly from the fact that all of this interactions will be done by m+n threads and there are various restrictions throughout the descriptions, like objectB can request something from objectA, and objectA has to wait for objectC to finish that something before returning it to objectB. Also each objectA thread can only work on one instruction from objectB at a time, etc. etc. I just want to know if I write the code so that there is only 1 objectA, 1 objectB and 1 object C, can I go back and easily modify it so that those 1's can be changed to m, n and r? Sorry again, if my description is a little bit confusing.

• Strategy for developing a multi function asp.net web application

  - by user247023

  I'm about to start a new project and want some advice on how to implement. I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out. If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules. to make things more difficult, there is some shared functionality like common users, roles and security. Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional. Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame. I can see that say, if I wanted to update the time management module, I would only need to build and release this separately, and the rest of the solution would be 'untouched' Any better alternatives?

• What is a reasonable OSGi development workflow?

  - by levand

  I'm using OSGi for my latest project at work, and it's pretty beautiful as far as modularity and functionality. But I'm not happy with the development workflow. Eventually, I plan to have 30-50 separate bundles, arranged in a dependency graph - supposedly, this is what OSGi is designed for. But I can't figure out a clean way to manage dependencies at compile time. Example: You have bundles A and B. B depends on packages defined in A. Each bundle is developed as a separate Java project. In order to compile B, A has to be on the javac classpath. Do you: Reference the file system location of project A in B's build script? Build A and throw the jar into B's lib directory? Rely on Eclipse's "referenced projects" feature and always use Eclipse's classpath to build (ugh) Use a common "lib" directory for all projects and dump the bundle jars there after compilation? Set up a bundle repository, parse the manifest from the build script and pull down the required bundles from the repository? No. 5 sounds the cleanest, but also like a lot of overhead.

• Class library reference problem

  - by Anindya Chatterjee

  I am building a class library and using its default namespace as "System". There suppose I am creating a generic data structure say PriorityQueue and putting it under System.Collections.Generic namespace. Now when I am referencing that library from another project, I can't see PriorityQueue under "System.Collections.Generic" namespace anymore. Though the library is referenced in that project I can not access any of the classes in it. My question was mscorlib and System.dll share similar namespaces, but still classes from both the assembly is accessible, but why can't mine? If I put a public class under System.Collections.Generic namespace in my class library and refer that library in a project and use a statement like "using System.Collections.Generic", still why I can't access my class there? This was an experimentation I did, I know using System namespace is not encouraged in custom class library, but I want to know the reason behind why I can't access my class in this special case? Please someone shed some light on it. PS: Last time I asked similar question but put it wrongly, so people got misunderstood and I didn't get my answer. This time I am trying to put it correctly as far as I can. Sorry for the misunderstanding.

• How to create Automation Add In Formula/Function and Excel Add In buttons (vsto) for them together?

  - by ticky

  Ok, let me explain it little bit better. Here is one example how to create formula/functions http://blogs.msdn.com/b/eric_carter/archive/2004/12/01/273127.aspx?PageIndex=1#comments I implemented something like that, I even added values in registry, so that this Automation AddIn doesn't have to be added manually in Excel, but automatically.. I created SETUP project for this project and it works GREAT. Then.. After some time, I wanted to create buttons in Excel for functions that I use. Those are custom functions, using some web services. I created Excel AddIn and added Ribbon with buttons - one button = one custom function. I can publish this project and I am creating VSTO, so this way, I can install excel ribbon buttons in custom group of mine. Now, I have 2 installations, first for Automation AddIn and second for Excel AddIn. How can I connect them? I tried to include VSTO to Setup - something like this: [I WILL ADD IT LATER] When I install it, it works great, it installs both parts. But when I install on my friends computer, it doesn't shows Ribbon buttons. What could be the problem? If there is some other way to integrate those two, I would be very grateful!!!!! Thanks! Tijana
