  • How to enable the video output on your iPad app?

    - by Sjakelien
    Just found out that the video output of the iPad is not a system level functionality, but that it needs to be explicitly build in into each app. Is there somebody who has any experience with this, who could point me to sample code? Secondary question would be: why wouldn't Apple make this a system feature. Is it a hardware issue, that I should be aware of when building this into my app?

  • Did Visual Studio 2010 break "Project Dependencies" between C++ projects?

    - by Roger Lipscombe
    In Visual Studio 2008, if I had a solution containing multiple C++ projects, I could make them depend on each-other and correctly link by using the "Project Dependencies" option. This fixed up the build order and also made (e.g.) the main application project link against the static library outputs. In Visual Studio 2010, this doesn't seem to work. Did Visual Studio 2010 change the way this works?

  • building list of child objects inside main object

    - by Asdfg
    I have two tables like this: Category: Id Name ------------------ 1 Cat1 2 Cat2 Feature: Id Name CategoryId -------------------------------- 1 F1 1 2 F2 1 3 F3 2 4 F4 2 5 F5 2 In my .Net classes, i have two POCO classes like this: public class Category { public int Id {get;set;} public int Name {get;set;} public IList<Feature> Features {get;set;} } public class Feature { public int Id {get;set;} public int CategoryId {get;set;} public int Name {get;set;} } I am using a stored proc that returns me a result set by joining these 2 tables. This is how my Stored Proc returns the result set. SELECT c.CategoryId, c.Name Category, f.FeatureId, f.Name Feature FROM Category c INNER JOIN Feature f ON c.CategoryId = f.CategoryId ORDER BY c.Name --Resultset produced by the above query CategoryId CategoryName FeatureId FeatureName --------------------------------------------------- 1 Cat1 1 F1 1 Cat1 2 F2 2 Cat2 3 F3 2 Cat2 4 F4 2 Cat2 5 F5 Now if i want to build the list of categories in my .Net code, i have to loop thru the result set and add features unless the category changes. This is how my .Net code looks like that builds Categories and Features. List<Category> categories = new List<Category>(); Int32 lastCategoryId = 0; Category c = new Category(); using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { //Check if the categoryid is same as previous one. //If Not, add new category. //If Yes, dont add the category. if (lastCategoryId != Convert.ToInt32(reader["CategoryId"])) { c = new Category { Id = Convert.ToInt32(reader["CategoryId"]), Name = reader["CategoryName"].ToString() }; c.Features = new List<Feature>(); categories.Add(c); } lastCategoryId = Convert.ToInt32(reader["CategoryId"]); //Add Feature c.Features.Add(new Feature { Name = reader["FeatureName"].ToString(), Id = Convert.ToInt32(reader["FeatureId"]) }); } return categories; } I was wondering if there is a better way to do build the list of Categories?

  • Wierdness debugging Visual Studio C++ 2008

    - by Jeff Dege
    I have a legacy C++ app, that in its most incarnation we've been building with makefiles and VS2003's command-line tool. I'm trying to get it to build using VS2008 and MsBuild. The build is working OK, but I'm getting errors where I'd never seen errors, before, and stepping through in VS2008's debugger only confuses me. The app links a number of static libraries, which fall into two categories: those that are part of the same application suite, and those that are shared between a number of application suites. Originally, I had a .csproj file for each static library, and two .sln files, one for the application suite (including the suite-specific libraries) and one for the non-suite-specific shared libraries. The shared libraries were included in the link, their projects were not included in the application suite .sln. The application instantiates an object from a class that is defined in one of the shared libraries. The class has a member object of a class that wraps a linked list. The constructor of the linked list class sets its "head" pointer to null. When I run the app, and try to add an element to the linked list, I get an error - the head pointer contains the value 0xCCCCCCCC. So I step through with the debugger. And see weirdness. When the current line in the debugger is in a source file belonging to the static library, the head pointer contains 0x00000000. When I step into the constructor, I can see the pointer being set to that value, and when I'm stepped into any other method of the class, I can see that the head pointer still contains 0x00000000. But when I step out into methods that are defined in the application suite .sln, it contains 0xCCCCCCCC. It's not like it's being overwritten. It changes back and forth depending upon which source file I am currently debugging. So I included the shared library's project in the application suite .sln, and now I see the head pointer containing 0xCCCCCCCC all the time. It looks like the constructor of the linked list class is not being called. So now, I'm entirely confused. Anyone have any ideas?

  • Can one edit an InstallShield setup.exe's manifest file?

    - by DNS
    I'm running into the Windows Vista/7 Program Compatibility Assistant problem described here: http://stackoverflow.com/questions/1069135/this-program-might-not-have-installed-correctly-message-in-windows-7-rc The solution (backed-up by similar questions elsewhere, and MSDN), is apparently to add a 'compatibility' section to setup.exe's manifest. InstallShield 10 SP1 does this automatically, but unfortunately I only have InstallShield 2009. How would I go about editing the manifest? Is there a way to do this programmatically, so I can integrate it into my build?

  • Jboss Seam Booking Example Extract Shared Libs From Ear

    - by michael lucas
    Example Booking Application, which JBoss Seam is shipped with, build into EAR file of about 7 MB. That's pretty much if you consider deploying this package to a remote Jboss server and possibly redeploying it package many times during your regular work. Lib files like richfaces and jsf-facelet make the lion's share of that EAR size. Why can't we just extract lib files into jboss-web.deployer directory on JBoss 4.2.0 GA server?

  • How to implement geo-based data store and computation?

    - by Mickey Shine
    Well, let me explain this briefly: 1.I want to build a website that provides location based services, like http://fireeagle.yahoo.net/ . 2.I guess most of these services have something do with longitude and latitude. 3.Is there any particular database/datastore/data structures fit well for such apps? I mean easy to store longitude, latitude and easy to compute or easy to use. I am new to this and any feedbacks are welcome

  • Any addins for VS2010 to support VS2005 projects?

    - by Eye of Hell
    Hello. Some of the old projects in our company are left to be built with VS2005 in autobuild system (making them build correctly in 2010 cost time). Is it any addins for VS2010 that will allow to open VS2005 project and edit it's files without converting project file itself to VS2010 format (converting will kill autobuild)? Of course i can create a separate project named "xxx_vs2010.vcproj" for each of such products, but that will be a mess :(.

  • "CruiseControl" Automation for C++ projects?

    - by Luciano
    We've got a C++ Project that currently uses Make on Linux to build. I'd like to automate it similar to a Java Project under CruiseControl. 1) Is there a project similar to CruiseControl for C++ projects? OR 2) Is there a good "how-to" on using CruiseControl for C++ Projects?
