• recognizing a link in an email

  - by Rob Bonner

  Is there a mechanism where I can identify a string in an email, say a order number, and have it route to my iPhone application? I know that base types do this, but not sure if I can create a new type for my app. Thanks!

• Why does my Sharepoint page's custom content type change to "Page" when editing?

  - by Mobius

  I have a custom Sharepoint 2007 site definition with custom content types for the different page layouts. When editing a page using a custom layout from the main "View all contents" tree view, the page content type is fine, but if I view the page directly and edit it from there, the content type gets stripped and replaced with "Page." I can change it back by viewing and editing it from the main list, but not from its subsite home location.

• 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" });

• How can I extend Eclipse Java search to JSPs?

  - by benhsu

  Friends, Our JSP code uses both Spring form tags and JSTL tags. Is there a way that when I search for getFoo() in the Eclipse Java Search, for Eclipse to also return uses of the foo property in the JSP files? I suspect the answer is "no", because there isn't a way at compile time to tell the types of the JSP beans, but its worth asking, right?

• 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.

• 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); }

• 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?

  In the following example we have two different exceptions we want to communicate. //constructor public Main(string arg){ if(arg==null) throw new ArgumentNullException("arg"); Thing foo=GetFoo(arg); if(foo==null) throw new NullReferenceException("foo is null"); } Is this the proper approach for both exception types?

• 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)

• 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?

• 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

• 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?

• 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?

• 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.

• Eclipse auto-complete of filenames

  - by Martin Tilsted

  Does anyone know if there exists a plugin to Eclipse which can auto complete filenames for files in the project. So if I type images/s [Alt+tab] it should present a list of all files located in images starting with s. Like the auto-complete for types but using filenames. It would be really cool if it worked with all kinds of editors.

• can I have an abstract base class with the key attribute being generic

  - by Greg

  Hi, I want to create a re-usable library. I was going to use extension methods however I run into some issues in some cases for the client to have to specify in the calling method the types. QUESTION - If I use an abstract base class as the basis, can I specify an attribute/property in the class to be generic (e.g. the key property might be an 'int' in one case, or a 'string' in another)?

• 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

• 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?
