I make it even simpler in one folder I put an app which on Run command runs and checks its existence. Lets says there are jpg images in it e.g image1 image2 image3 then it loops checking if there is more. If there is nothing it just keeps running and if there are new it just updates.

I'm not sure what you want from me here. It sounds like you know exactly what you have to do here, so good luck with it. Please feel free to come back with any specific problems you have.

Entity Framework, Import Function Stored Procs & Data Services

Hi

I'm hoping someone can point me in the right direction.

I'm trying to use EF within a Data Service, returning data from a SQL stored procedure.

I've successfully followed the quickstart here http://msdn.microsoft.com/en-us/library/dd728275.aspx[^] to get a basic service up & running against my own DB, rather than Northwind.

I've found this article telling me how to expose stored procedures http://msdn.microsoft.com/en-us/data/gg699321.aspx[^], which creates the expected public ObjectResult<t> entry in the model, but when my service tries to do the

Quote:
config.SetServiceOperationAccessRule("GetContact", ServiceOperationRights.AllRead);

I get the error 'The given name 'GetContact' was not found in the service operations', even though I can see it as a public method in the object browser.

I have also found this article http://msdn.microsoft.com/en-us/library/cc668788.aspx[^] saying that to be exposed as a service operation for the service, it must return viod, IQueryable, IEnumerable, priomitive type or an entity type in the model.

How do I reconcile the latter requirement with the former ObjectResult way of doing things. My Google skills have failed me, so pointers to documentation will be welcome.

Regards, Stewart

Take your time to formulate a question; as it is now, I'd simply point to the documentation and answer "use it correctly".

What is it, specifically, that you need help with, or want advise on?

Hi, I recently found that knowing a .NET programming language itself isn't enough to become a pro .NET developer. So my question is where can I find best ebooks about knowing .NET framework structure, deeply and completely?

.NET developer is very a broad term; it does not imply that you lack in-depth knowledge of the for loops, but that there are "area's" that you could still explore.

.NET can be used to develop web-apps, cross-platform desktop-apps and mobile apps. Did you try all three of those? Desktop can be divided into various GUI-concepts, like WinForms, WPF and Gtk#. Besides that, .NET offers some various additional technologies that are interesting to learn, like serialization, the MEF-framework, WCF and WF.

Amazon, Manning, Google. Brownfield development[^] is a good place to start; even for greenfields Smile | :)

If you seriously want to dive deeper in the way .NET works, I suggest you Google for some CodeProject-article's on IL.

If you can specify what area of development you're targetting, you'll get a bit more specific answer.

You have targetted the Client Profile in your project (take a look in the project properties). This doesn't include the web assemblies. You need to change your profile to the full .NET 4 profile to get access to System.Web.

Jagged Array as Return Type from Function - Syntax Driving me Bonkers

M-Badger25-Sep-12 6:50

25-Sep-12 6:50

For love nor money I cannot get the syntax right.
I want to return 3 x 2D arrays from a function but can't wrap my head around it - I suspect I have just failed to grasp some fundamental aspect of jagged arrays!

Public Function SVD() As Double(,)(,)(,)
    Dim arS(,) As Double
    Dim arU(,) As Double
    Dim arV(,) As Double

    ...Fill the Arrays...
    
     Dim arSVD(,)(,)(,) As Double
     
     arSVD(0) = arS
     arSVD(1) = arU
     arSVD(2) = arV

     Return arSVD
End Function

If I have it that way the error is on arSVD(n) and says 'Number of indices is less than the number of dimensions...'

If I change the return type and arSVD to Double()()() then the error is on the last arS and says 'Value of type 2D array cannot be converted to 1D array...'

If I change it to arSVD(0,0) for example the error is on the last arS and says 'Value of type 2D array cannot be converted to type 2D array of 2D array...'

Bash. Head. Brick. Wall.

Any help very gratefully received.

Wow, I'd forgotten just how horrible VB's array syntax[^] is! Poke tongue | ;-P

Try this:

Public Function SVD() As Double()(,)
   Dim arS(,) As Double
   Dim arU(,) As Double
   Dim arV(,) As Double

   Dim arSVD(2)(,) As Double
   arSVD(0) = arS
   arSVD(1) = arU
   arSVD(2) = arV

   Return arSVD
End Function

Probably also worth noting, for posterity, that I solved this problem using a structure, 3 private members as double(,) and a constructor that takes the same as paramaters and off you go - quite a few advantages of doing it this way and I could also add a second constructor using just one parameter, the syntax Richard gave : ()(,) as double.
