• To OpenID or not to OpenID? Is it worth it?

  - by Eloff

  Does OpenID improve the user experience? Edit Not to detract from the other comments, but I got one really good reply below that outlined 3 advantages of OpenID in a rational bottom line kind of way. I've also heard some whisperings in other comments that you can get access to some details on the user through OpenID (name? email? what?) and that using that it might even be able to simplify the registration process by not needing to gather as much information. Things that definitely need to be gathered in a checkout process: Full name Email (I'm pretty sure I'll have to ask for these myself) Billing address Shipping address Credit card info There may be a few other things that are interesting from a marketing point of view, but I wouldn't ask the user to manually enter anything not absolutely required during the checkout process. So what's possible in this regard? /Edit (You may have noticed stackoverflow uses OpenID) It seems to me it is easier and faster for the user to simply enter a username and password in a signup form they have to go through anyway. I mean you don't avoid entering a username and password either with OpenID. But you avoid the confusion of choosing a OpenID provider, and the trip out to and back from and external site. With Microsoft making Live ID an OpenID provider (More Info), bringing on several hundred million additional accounts to those provided by Google, Yahoo, and others, this question is more important than ever. I have to require new customers to sign up during the checkout process, and it is absolutely critical that the experience be as easy and smooth as possible, every little bit harder it becomes translates into lost sales. No geek factor outweighs cold hard cash at the end of the day :) OpenID seems like a nice idea, but the implementation is of questionable value. What are the advantages of OpenID and is it really worth it in my scenario described above?

• supress warning for generated c# code

  - by soren.enemaerke

  I have turned on "Treat warnings as errors" for my VS project which mean that I get errors for missing documentation (nice reminder for this particular project). However, part of the code is generated by a custom tool which does not insert xml documentation so I'm looking for away to ignore the missing xml documentation for the generated code only, not for the entire project. I have no influence on the actual file generated and cannot really insert anything in the file (as it is regenerated frequently by the tool) so I looking for something existing outside the generated file (the classes that are generated are partial, if that helps)

• How is "Make Object ID" implemented in the .NET debugger?

  - by Omer Raviv

  Hi, I would like know how this feature is implemented in VS - I understand it holds some sort of weak-reference to the object in the debugged-application's memory, but how exactly is it accomplished? I know simply tracking the address (as in native code) wouldn't work, because the GC might move the object about, invalidating the address. Thanks.

• User Interface Diagram That is always reachable

  - by Fosa

  If you have to build a flow of a Use-case by drawing each Interface Diagram. Then you would start with a Diagram like say "login". But after the login page, no mather wich page you choose except the "logout" page, you always have your navigation bar right ? So all the options in the navigation bar? Like account page , personal page, etc... Do you have to make sure in your flow that in every diagram there is acces to the "accountpage" diagram ? Or do they have an other solution for that ? Thanx in advance

  Saw a post about hidden features in C# but not a lot of people have written linq/lambdas example so... I wonder... What's the coolest (as in the most elegant) use of the C# LINQ and/or Lambdas/anonymous delegates you have ever saw/written? Bonus if it has went into production too!

• Publish failed in Web Application Project (MVC)

  - by Stuck

  I usually use the "Publish" feature in VS 2008 to get the correct files and so on that I can publish to my website. But from time to time publish fails without any good error message at all. I know that it can be a couple of different reasons but I am starting to grow really tired with this now. Can anyone teach me how to build the website from the command line? As I said it is a MVC project. Can I use the aspnet_compiler for this? What parameters should I use to simulate the same behavior as a "Publish"?

• How can I embed images within my application and use them in HTML control?

  - by Atara

  Is there any way I can embed the images within my exe (as resource?) and use it in generated HTML ? Here are the requirements: A. I want to show dynamic HTML content (e.g. using webBrowser control, VS 2008, VB .Net, winForm desktop application) B. I want to generate the HTML on-the-fly using XML and XSL (file1.xml or file2.xml transformed by my.xsl) C. The HTML may contain IMG tags (file1.gif and or file2.gif according to the xml+xsl transformation) and here comes the complicated one: D. All these files (file1.xml, file2.xml, my.xsl, file1.gif, file2.gif) should be embedded in one exe file. I guess the XML and XSL can be embedded resources, and I can read them as stream, but what ways do I have to reference the image within the HTML ? <IMG src="???" /> I do not want to use absolute path and external files. If the image files are resources, can I use relative path? Relative to what? (I can use BASE tag, and then what?) Can I use stream as in email messages? If so, where can I find the format I need to use? http://www.websiteoptimization.com/speed/tweak/inline-images/ are browser dependent. What is the browser used by webBrowser control? IE? what version? Does it matter if I use GIF or JPG or BMP (or any other image format) for the images? Does it matter if I use mshtml library and not the regular webBrowser control? (currently I use http://www.itwriting.com/htmleditor/index.php ) Does it matter if I upgrade to VS 2010 ? Thanks, Atara

• Compiler #defines for g++ and cl

  - by DHamrick

  I am writing a program that is cross platform. There are a few spots where I have to specify an operating system dependent call. #ifdef WINDOWS ..do windows only stuff #endif #ifdef LINUX ..do linux only stuff #endif Are there any preprocesser directives that get defined by the compiler so I don't have to explicitly define them when I use the command line compiler. ie. cl -DWINDOWS program.cpp or g++ -DLINUX program.cpp I realize I could easily write a makefile or have a shell/batch script that will do this automatically. But I would prefer to use the same ones as the compiler (if they exist) by default.

• MSVC 2003 doesn't see any definitions from a nested include file

  - by ezpresso

  I have a piece of code with COM class declaration as follows: #include "PathTypes.h" MIDL_INTERFACE("552C7555-0555-4444-BA86-56CF39AAFFFF") IPathCalc : public IUnknown { virtual HRESULT STDMETHODCALLTYPE GetLocation( /* [retval][out] */ GeoLocation* pLoc) = 0; virtual HRESULT STDMETHODCALLTYPE SetLocation( /* [in] */ GeoLocation* pLoc) = 0; ... }; Below is the contents of PathTypes.h file: #if !defined(PATHCALC_TYPES_INCLUDED) #define PATHCALC_TYPES_INCLUDED #include "libastro/AstronomyStructs.h" #endif And the libastro/AstronomyStructs.h from an external cross-platform library: #ifndef _ASTRONOMY_STRUCTS_INCLUDED #define _ASTRONOMY_STRUCTS_INCLUDED typedef struct { double lattitude; double longitude; } GeoLocation; ... #endif /* _ASTRONOMY_STRUCTS_INCLUDED */ When I'm trying to build this code with g++ everything goes well. That's not the case with MSVC 2003 which returns error C2061: syntax error : identifier 'GeoLocation'. Seems like MSVC doesn't "see" the definitions from the libastro/AstronomyStructs.h file. When I replace #include "PathTypes.h" with #include "libastro/AstronomyStructs.h" the code compiles without errors. How to make MSVC 2003 to actually "see" the definitions from the nested include files?

• Is there a way to add extra fields to an association in the ADO.NET Entity Framework?

  - by bigbird1040

  I would like to be able to model a many-to-many relationship that has extra details about the relationship. For example: Person: int id, String name Project: int id, String name ProjectPerson: Person.id, Project.id, String role Whenever I create the ProjectPerson association in the EF, I am unable to add the role attribute to the association. If I create the tables in my DB and then import it into the model, I lose the extra properties.

• Call a function from another Class - Obj C

  - by AndrewDK

  I'm trying to figure out how I can call a function from another one of my classes. I'm using a RootViewController to setup one of my views as lets say AnotherViewController So in my AnotherViewController im going to add in on the .h file @class RootViewController And in the .m file im going to import the View #import "RootViewController.h" I have a function called: -(void)toggleView { //do something } And then in my AnotherViewController I have a button assigned out as: -(void)buttonAction { //} In the buttonAction I would like to be able to call the function toggleView in my RootViewController. Can someone clarify on how I do this. I've tried adding this is my buttonAction: RootViewController * returnRootObject = [[RootViewController alloc] init]; [returnRootObject toggleView]; But I dont think that's right. Thanks in advanced.

• MS Dev Studio 2005 Ignores Preprocessor directives during compile

  - by miked

  We just got a new developer and I'm trying to set him up with Dev Studio 2005 (The version we all use at this office), and we're running into a weird problem that I've never seen before. I have some code that works perfectly on my system, and he can't seem to get it compiled. We've tracked the issue down to his copy of dev studio ignoring the preprocessor directives. For example, in the project properties under C/C++|Preprocessor|Preprocessor Directives, I add DEFINE_ME. Which should translate to a /D"DEFINE_ME" for the compiler. And it does in my development environment, but it doesn't on his. I verified that when he checks out the code from the source repository, that he has the same version of the code I do. And if I look in his Project Properties, all of the directives are there. For some reason they're just not getting passed down to the compiler. Any Ideas?

• Managed DirectX as a starting point

  - by numerical25

  I know the difference between manage and unmanaged DirectX. My question is if I decided to do managed directX as a starting point, would it help me to better understand unmanaged DirectX. Honestly, the only thing I see different about the 2 is how you initiate and access resources. Matrix Math is Matrix no matter what so If I learn it in managed, then I should be fine in unmanaged

• Supporting Piping (A Useful Hello World)

  - by blastthisinferno

  I am trying to write a collection of simple C++ programs that follow the basic Unix philosophy by: Make each program do one thing well. Expect the output of every program to become the input to another, as yet unknown, program. I'm having an issue trying to get the output of one to be the input of the other, and getting the output of one be the input of a separate instance of itself. Very briefly, I have a program add which takes arguments and spits out the summation. I want to be able to pipe the output to another add instance. ./add 1 2 | ./add 3 4 That should yield 6 but currently yields 10. I've encountered two problems: The cin waits for user input from the console. I don't want this, and haven't been able to find a simple example showing a the use of standard input stream without querying the user in the console. If someone knows of an example please let me know. I can't figure out how to use standard input while supporting piping. Currently, it appears it does not work. If I issue the command ./add 1 2 | ./add 3 4 it results in 7. The relevant code is below: add.cpp snippet // ... COMMAND LINE PROCESSING ... std::vector<double> numbers = multi.getValue(); // using TCLAP for command line parsing if (numbers.size() > 0) { double sum = numbers[0]; double arg; for (int i=1; i < numbers.size(); i++) { arg = numbers[i]; sum += arg; } std::cout << sum << std::endl; } else { double input; // right now this is test code while I try and get standard input streaming working as expected while (std::cin) { std::cin >> input; std::cout << input << std::endl; } } // ... MORE IRRELEVANT CODE ... So, I guess my question(s) is does anyone see what is incorrect with this code in order to support piping standard input? Are there some well known (or hidden) resources that explain clearly how to implement an example application supporting the basic Unix philosophy? @Chris Lutz I've changed the code to what's below. The problem where cin still waits for user input on the console, and doesn't just take from the standard input passed from the pipe. Am I missing something trivial for handling this? I haven't tried Greg Hewgill's answer yet, but don't see how that would help since the issue is still with cin. // ... COMMAND LINE PROCESSING ... std::vector<double> numbers = multi.getValue(); // using TCLAP for command line parsing double sum = numbers[0]; double arg; for (int i=1; i < numbers.size(); i++) { arg = numbers[i]; sum += arg; } // right now this is test code while I try and get standard input streaming working as expected while (std::cin) { std::cin >> arg; std::cout << arg << std::endl; } std::cout << sum << std::endl; // ... MORE IRRELEVANT CODE ...

• Tfs 2010: how to set up a corporate source server?

  - by bwerks

  Hi all, I'm looking for guidance in setting up a corporate source server, but when I google this topic the best I can come up with is articles and walkthrough concerned with configuring VS to use microsoft's public symbol servers for use with debugging .NET assemblies. Provided for background info, the environment I'm concerned with using is Vs2010/Tfs2010. Basically, the workflow I'm looking to facilitate is this: 1) customer reports problem with application 2) application of the appropriate version is installed on a virtual machine 3) developer repros bug attaching to process on virtual machine and leveraging source server (symbol server?) on corporate domain. This is the step I'm concerned with. 4) developer pinpoints problem fixes bug in workspace. 5) developer performs a dll swap on VM to test changes? (side topic, not sure on this) 6) normal development/source control workflows. Any advice is welcome! Edit: since writing this, I have stumbled on this article, which is a nice writeup on the configuration of source server for TFS 2008. Has anyone adapted this for Tfs 2010?

• How to get spacing between characters printed using TextOut ?

  - by life-warrior

  I'm trying to calcuate size of each cell (containing text like "ff" or "a0"), so that 32 cells will fit into window by width. However, charWidth*2 doesn' represent the width of a cell, since it doesn't take spacing between characters in the account. How can I obtain size of a font so that 32 cells each is two chars like "ff" fit exactly into window's client area ? Curier is fixed-width font. RECT rect; ::GetClientRect( hWnd, &rect ); LONG charWidth = (rect.right-rect.left)/BLOCK_SIZE/2-2; int oldMapMode = ::SetMapMode( hdc, MM_TEXT ); HFONT font = CreateFont( charWidth*2, charWidth, 0, 0, FW_DONTCARE, FALSE, FALSE, FALSE, DEFAULT_CHARSET, OUT_OUTLINE_PRECIS, CLIP_DEFAULT_PRECIS, CLEARTYPE_QUALITY, FF_ROMAN, _T("Courier") ); HGDIOBJ oldFont = ::SelectObject( hdc, font ); for( int i = 0; i < BLOCK_SIZE; ++i ) { CString str; str.Format( _T("%.2x"), (unsigned char)*(g_memAddr+i) ); SIZE size; ::TextOut( hdc, (size.cx+2)*i+1, 1, str, _tcslen((LPCTSTR)str) ); }

• Right rotate of tree in Haskell: how is it work?

  - by Roman

  I don't know haskell syntax, but I know some FP concepts (like algebraic data types, pattern matching, higher-order functions ect). Can someone explain please, what does this code mean: data Tree ? = Leaf ? | Fork ? (Tree ?) (Tree ?) rotateR tree = case tree of Fork q (Fork p a b) c -> Fork p a (Fork q b c) As I understand, first line is something like Tree-type declaration (but I don't understand it exactly). Second line includes pattern matching (I don't understand as well why do we need to use pattern matching here). And third line does something absolutely unreadable for non-haskell developer. I've found definition of Fork as fork (f,g) x = (f x, g x) but I can't move further anymore.

• Distributing iPhone App to developers in your team through iTunes

  - by Rudiger

  Hi everyone, Was wondering if you can distribute your App to other developers in your team through iTunes. I guess you would upload the App as a beta version through iTunes Connect and anyone with a provisioned iPhone would receive the update. I didn't think it was possible but someone told me they were sure you could. If this is not possible are there any other benefits of a company standard enrolment besides being able to add other people so they can get the same resources? Thanks

• Adding Runtime Intelligence Application Analytics for a library and not an application

  - by brickner

  I want to add usage statistics for a .NET 4.0 library I write on CodePlex. I try to follow the step described here but my problem lies with the fact that what I write is a library and not an application. One of the steps is put the Setup and Teardown attributes. I thought about adding the Setup attribute on a static constructor or a different place that will run once per usage of the library. My problem lies with the Teardown attribute that should be placed on code that ends the usage. I don't know where to put this attribute. Is it possible to get usage statistics on a library? Maybe I can register on an event that will fire when the application unloads the dll?
