• Re: Circular Dependecy

  The simplest way is to put them in the same class library. I normally separate my class libraries according to which layer of the solution architecture they represent so in my case Product and Category would be in the same class library anyway. Other than that the only other thing I can think of is to create another class library containing an IProduct and an ICategory interface and have both other class libraries reference the interface class library. You would need to declare all types of Product

• Re: Object reference not set to an instance of an object error

  One of the objects you are attempting to dereference somewhere in the try block is null. A quick and easy way to find the problem will be to set a breakpoint inside the catch block and inspect the Exception.StackTrace to find where the exception is thrown and narrow down the search for the null reference from there. Having a quick browse over your code, the HideForm() and BindData() stand out to me because a) the rest of the posted code doesn't seem to have any places where an object is deferenced

• Re: ListView Hide if Null

  Ok, It's been a while since I've done much ASP.Net development so you might have to double check the syntax here but I think you should be able to do something like this: [quote user="x2voyager"] <asp:ListView ID="lvFoo" runat="server" DataKeyNames="ID" DataSourceID="sdsFoo" GroupItemCount="3"> <EmptyItemTemplate> <td runat="server" /> </EmptyItemTemplate> <ItemTemplate> <td runat="server"

• Re: Help with DAL / BLL Question

  I use a thin security layer ontop of the BLL. It implements the same interface as the corresponding BLL component (eg ICompanyService) and calls the corresponding BLL component but also performs all necessary security checks and returns different sets of data based on user roles and custom security rules. I put both components into a service container - with the security component being the default one for the interface type (ICompanyService). This way when I get ICompanyService out of the service

• Re: Performance

  It would make sense to remove references to assemblies not used by your project to increase performance but as the previous poster pointed out, removing unneccessary Using statements won't help performance. It does help keep your code tidy though, so I would do it anyway.

• Re: Path to an Architect

  I am doing the same thing as you czuvich. I have decided that a combination of certification, degrees and experience will give me the best possible foundation and the most opportunity. In the past it's been proven to me in more than one situation that experience is worth more than formal qualifications however there are also alot of cases where a company won't even consider you if you dont have X certification or Y degree. So the path I have chosen is to continue working full time, getting

• Re: Code Patterns

  [quote user="gumby2701"]I can see that with the SoC idea you could end up with heaps of interfaces. I mean how far do you go ie (One interface to save, another to insert , delete etc etc). Are there any websites/books which help conceptually of how to design the layers because Im not sure how to think n level deep :) [/quote] Generally each class that will reside in the service container is interfaced. You don't have to have a seperate class for each method (eg. Save, Update, Delete
