  • Keep data with specific value on top when sorting a gridview

    - by aspNetAficionado
    Hi i have a gridview with information about documents: name, document type (policy, guidelines, forms, etc), category, etc. I want to sort the gridview alphabetically (name) and by document type, but always having the 'policy' above the other document types when document name is the same. How do I do that? eg If I do sort by DocumentName, DocumentType ('policy' maybe not be the first one in the list) but if I do sort by DocumentType , DocumentName (I would get for example all guidelines first in alphabetical order, then procedures, then policies, etc)

  • Generics and anonymous type

    - by nettguy
    I understood,normally generics is for compile time safe and allow us to keep strongly typed collection.Then how do generic allow us to store anonymous types like List<object> TestList = new List<object>(); TestList.Add(new { id = 7, Name = "JonSkeet" }); TestList.Add(new { id = 11, Name = "Marc Gravell" }); TestList.Add(new { id = 31, Name = "Jason" });

  • Drawbacks of using an integer as a bitfield?

    - by Mark
    I have a bunch of boolean options for things like "accepted payment types" which can include things like cash, credit card, cheque, paypal, etc. Rather than having a half dozen booleans in my DB, I can just use an integer and assign each payment method an integer, like so PAYMENT_METHODS = ( (1<<0, 'Cash'), (1<<1, 'Credit Card'), (1<<2, 'Cheque'), (1<<3, 'Other'), ) and then query the specific bit in python to retrieve the flag. I know this means the database can't index by specific flags, but are there any other drawbacks?

  • How can I declare an object with properties that I will be passing around inside of my function using Typescript?

    - by Marilou
    I've been using the following: var modal = { content: '', form: '', href: '' } But now I have started to use Typescript is there a better way I can declare an object and how can I declare the types of my properties. The reason I am using this object is that it's inside of a function and inside that function I have other functions that set and use the values of the properties. Is this the best way for me to do this or is there another way I could better do this with typescript?

  • What alternatives to __attribute__ exist on 64-bit kernels?

    - by Saifi Khan
    Hi: Is there any alternative to non-ISO gcc specific extension __attribute__ on 64-bit kernels ? Three types that i've noticed are: function attributes, type attributes and variable attributes. eg. i'd like to avoid using __attribute__((__packed__)) for structures passed over the network, even though some gcc based code do use it. Any suggestions or pointers on how to entirely avoid __attribute__ usage in C systems/kernel code ? thanks Saifi.

  • Can i use a generic implicit or explicit operator? C#

    - by acidzombie24
    How do i change the following statement so it accepts any type instead of long? Now here is the catch, if there is no constructor i dont want it compiling. So if theres a constructor for string, long and double but no bool how do i have this one line work for all of these support types? ATM i just copied pasted it but i wouldnt like doing that if i had 20types (as trivial as the task may be) public static explicit operator MyClass(long v) { return new MyClass(v); }

  • Hibernate many-to-one - bad usage?

    - by DaveA
    Just trying out Hibernate (with Annotations) and I'm having problems with my mappings. I have two entity classes, AudioCD and Artist. @Entity public class AudioCD implements CatalogItem { @Id @GeneratedValue(strategy = GenerationType.AUTO) private int id; private String title; @ManyToOne(cascade = { CascadeType.ALL }, optional = false) private Artist artist; .... } @Entity @Table(uniqueConstraints = { @UniqueConstraint(columnNames = { "name" }) }) public class Artist { @Id @GeneratedValue(strategy = GenerationType.AUTO) private int id; @Column(nullable = false) private String name; ..... } I get AudioCD objects from an external source. When I try to persist the AudioCD the Artist gets persisted as well, just like I want to happen. If I try persisting another different CD, but Artist already exists I get errors due to constraint violations. I want Hibernate to recognise that the Artist already exists and shouldn't be inserted again. Can this be done via annotations? Or do I have to manage the persistence of the AudioCD and Artist seperately?

  • C# Dictionary<> and mutable keys

    - by Pierreten
    I was told that one of the many reasons strings were made immutable in the C# spec was to avoid the issue of HashTables having keys changed when references to the string keys altered their content. The Dictionary< type allows reference types to be used as a key. How does the dictionary avoid the issue of altered keys that lead to "misplaced" values? Is there a memberwise clone made of an object when used as a key?

  • what are LPARAM and WPARAM defined as

    - by Mark Heath
    I know I'm being lazy here and I should trawl the header files for myself, but what are the actual types for LPARAM and WPARAM parameters? Are they pointers, or four byte ints? I'm doing some C# interop code and want to be sure I get it working on x64 systems.

  • Additional concerns when compiling for x64

    - by dotnetdev
    I know that the additional consideratiosn when compiling for x64 is that some data types, like ints, can hold larger values. Are there any concerns? VS2010, released a few days ago, can support compiling for x64 and x32, just like VS2008. The app is x32/86 only. I keep thinking that the app needs to be 64 bit however. What am I missing? Obviously this is not the case. Thanks

  • set include_path for embed files like .js and .css?

    - by John Isaacks
    OK so I now know there is a way to put all my php files in a single place and have them be able to be included without a filepath by setting an include_path like so: php_value include_path .:/pathToPHPFiles OK so now as long as my PHP files are in this directory I can include them from any subdirectory as if they were in the same directory. I am wondering if there is a trick like this for other file types like .css and .js so I can put them all in single location and embed them in a page without worring about the filepath?

  • Another void C# question

    - by Jim Jones
    Have a type in the header files I'm working with called VTVOID it is the type of a struct element and a number of parameters. In the header file defining types is the line #define VTVOID void I read in another discussion the void maps to System.Void however when I plug that into the C# code I get the error "System.Void cannot be used in C# -- use typeof(void) to get the void object." So what type do I plug in? Jim

  • Routing to a different URLs based on post type

    - by DanCake
    What would be the best way to set up my routes so different types of posts have different URLs? For example, regular posts are /posts/slug while featured posts are /featured/slug Both link to the same controller and action /posts/view/slug. I experimented with different ways of doing this but with little success. Currently my link params look something like the following: array('controller' => 'posts', 'action' => 'view', 'featured' ,$post['Post']['slug'])
