I am creating an install script for a Sql server 2008 database using Tasks =>generate Scripts option. This works fine and creates a script including database,schema and seed data.

One problem I notice is that the A Stored procedure is created before the table it refers to is created and this gives error when creating the database.

I would like create a MVC3 website. I have existing dlls packaged as .net MSI which are installed into the GAC. What is the best way to reference these update-able dlls in MVC3? They will always be installed into the GAC, their version number will be updated accordingly. I don't want to have to manually reference them in my MVC3 project, as every time I re install, the reference will break and I have to update my dependent dll references.

\n\n

Any input would be appreciated. I have looked around for solutions already but nothing seems straight forward.

Jason Dolinger in his video located here (hot available right now) www.lab49.com/files/videos/Jason%20Dolinger%20MVVM.wmv (from 0.59 to 1.04) uses such code:

\n\n
public partial App: Application\n{\n    protected override void OnStartup(StartupEventArgs e)\n    {\n        base.OnStartup(e);\n        IUnityContainer container = new UnityContainer();\n        RandomQuoteSource source = new RandomQuoteSource();\n        container.RegisterInstance<IQuoteSource>(source);\n\n        WatchList window = container.Resolve<WatchList>();\n        window.Show();\n    }\n}\n
\n\n

He uses class IUnityContainer which I can not found. As I understand here we just create a window (so container.Resolve call can be replaced with new WatchList(..., also somehow we associate RandomQouteSource as an implementation for IQouteSource, however I don't have clear understanding how this should be used later.

\n\n

The questions are:

\n\n
    \n
  • how do you create main Windows in your MVVM application, do you also use IUnityContainer for that?
    • \n
  • is it good technics in general? is it well-known? is it default way to do these things? what alternativies do I have?
    • \n
  • where can I find Microsoft.Practicies.Unity.dll?

I have been playing around with variadic templates in the new c++ standard and came up with a map function (headers + using decs excluded):

\n\n
template<typename T>\nT square(T i)\n{\n        return i * i;\n}\n\ntemplate <typename T, typename... Ts>\nconst tuple<Ts...> map(const T f, const Ts...args)\n{\n        return make_tuple(f(args)...);\n}\n\nint main(int c, char *argv[])\n{\n        tuple<int, int> t;\n        int (*fp) (int) = square;\n\n        t = map(fp, 6, 8);\n\n        cout <<get<0>(t) <<endl;\n        cout <<get<1>(t) <<endl;\n\n        return 0;\n}\n
\n\n

Which works. As long as all the arguments are the same type for map. If I change the main to use a slightly more general form:

\n\n
 tuple<int, float> t;\n\n t = map(square, 6, 8.0f);\n
\n\n

gcc 4.4 reports:

\n\n
In function \u2018int main(int, char**)\u2019:\nerror: no matching function for call to \u2018map(<unresolved overloaded function type>, int, float)\u2019\n

Any ideas how to make this work?

This question is another problem im having with my application which is described here. My model (a level) has a list of requirements which contains two strings, an id and name. The model looks like this:

\n\n
public class Level {\nprivate String name;\nprivate int id;\nprivate int points\nprivate List<Requirement> requirements;\n    ....\n}\n\npublic class Requirement{\n    private String name;\n    private String id;\n    ....\n}\n
\n\n

and the jsp looks like this:

\n\n
<div id=\"allRequirements\">\n    <c:forEach var=\"requirement\" items=\"${RequirementList}\">\n         <div class=\"requirements\">\n             <input type=\"hidden\" value=\"${requirement.id}\" name=\"id\"/>\n             <h2><c:out value=\"${requirement.name}\"/></h2>\n         </div>\n    </c:foreach>\n</div>\n\n<div id=\"requiredRequirements\">\n    <c:forEach var=\"requiredRequirement\" items=\"${level.requirements}\">\n         <div class=\"requirements\">\n             <input type=\"hidden\" value=\"${requiredRequirement.id}\" name=\"id\"/>\n             <h2><c:out value=\"${requiredRequirement.name}\"/></h2>\n         </div>\n    </c:foreach>\n</div>\n
\n\n

The jsp page renders fine and works like a charm until I added the requiredRequirements loop in which the site throws a java.lang.NumberFormatException: For input string: \"id\" because it tries to parse the string as an int.

\n\n

Does anyone have any idea why the first loop works and the second loop does not work?
