From what I read, PHP 6 will break a lot of php scripts. I understand the reasons why it may break but why don't they just keep the PHP 5 and simply call PHP 6 as a different language based on PHP syntax? Like for example, why not just call php 6 scripts with an extension, "p6"- why are they trying so hard to make it backward compatible for old scripts when the extension can be used to call a specific interpreter?
Hi,
Iam using
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String bestProvider = locationManager.getBestProvider(criteria, true);
locationManager.requestLocationUpdates(bestProvider, 0, 0, this);
location = locationManager.getLastKnownLocation(bestProvider);
but first time it is not giving location object.Always giving me null.I read in developer.android.com ,
"Cached Location is dismissed if it is
too old"
But second time it is giving location updates.How to solve my problem.

So I've spent a lot of time making an iPhone game and have recently realized that I don't have to limit myself to just Apple - I know there are app stores for Palm and Android, but does anybody know of a good "app store" for the plain old PC? I would like to have one where individual developers can publish an app and not have to worry about all the billing and piracy issues!
Follow is my trigger of Sybase ASA 8.0 script:
Create trigger dba.test after insert,delete,update order 1 on
DBA.tb_press
referencing old as _old new as _new
for each row
begin
--How to detect deleteOperate,updateOperate?
if deleteOperate then
insert into syncLog(tableName,keyId,version,operate)
select tb_press,_old.id,1,'delete'
end if;
end
how to determine whether to insert ,update,delete operate.
I have a large web app, and I think there are a bunch of old files that are no longer being used, is there an app which can tell me what these files are?
I am developing an app that relies heavily on an external dll, my app needs to support new versions of the dll as well as being backwards compatible with the old ones.
Are there any good ways to have my unit tests target all of these different dll versions without the need to rewrite the tests as soon as a new version of the api is released? How is this best handled?
Thanks!
i have this querystring that shall open up my page.
http://www.a1-one.com/[email protected]&stuid=123456
Now when this page loads, on page_load, I want to pick up email and stuid in two different variables. So I can use them to insert into my database (sql server)
how can this be done in vb.net
Is there a way to make a popup window maximised as soon as it is opened? If not that, at least make it screen-sized? This:
window.open(src, fullscreen="yes")
apparently only worked for old version of IE.
My table structure looks like this:
create table rankings (
id IDENTITY NOT NULL,
user_id INT NOT NULL,
game_poule_id INT NOT NULL,
rank INT NOT NULL,
insertDate DATETIME NOT NULL,
FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE,
FOREIGN KEY (game_poule_id) REFERENCES game_poules(id) ON DELETE CASCADE
);
All old rankings of users per game are saved in this table. Now I want to have the last but one rank in the table for all users in a gamepoule.
Has someone an idea how to achive this? Thanks
(EDIT: I made it a community wiki as it is more suited to a collaborative format.)
There are a plethora of ways to access SQL Server and other databases from .NET. All have their pros and cons and it will never be a simple question of which is "best" - the answer will always be "it depends".
However, I am looking for a comparison at a high level of the different approaches and frameworks in the context of different levels of systems. For example, I would imagine that for a quick-and-dirty Web 2.0 application the answer would be very different from an in-house Enterprise-level CRUD application.
I am aware that there are numerous questions on Stack Overflow dealing with subsets of this question, but I think it would be useful to try to build a summary comparison. I will endeavour to update the question with corrections and clarifications as we go.
So far, this is my understanding at a high level - but I am sure it is wrong...
I am primarily focusing on the Microsoft approaches to keep this focused.
ADO.NET Entity Framework
Database agnostic
Good because it allows swapping backends in and out
Bad because it can hit performance and database vendors are not too happy about it
Seems to be MS's preferred route for the future
Complicated to learn (though, see 267357)
It is accessed through LINQ to Entities so provides ORM, thus allowing abstraction in your code
LINQ to SQL
Uncertain future (see Is LINQ to SQL truly dead?)
Easy to learn (?)
Only works with MS SQL Server
See also Pros and cons of LINQ
"Standard" ADO.NET
No ORM
No abstraction so you are back to "roll your own" and play with dynamically generated SQL
Direct access, allows potentially better performance
This ties in to the age-old debate of whether to focus on objects or relational data, to which the answer of course is "it depends on where the bulk of the work is" and since that is an unanswerable question hopefully we don't have to go in to that too much. IMHO, if your application is primarily manipulating large amounts of data, it does not make sense to abstract it too much into objects in the front-end code, you are better off using stored procedures and dynamic SQL to do as much of the work as possible on the back-end. Whereas, if you primarily have user interaction which causes database interaction at the level of tens or hundreds of rows then ORM makes complete sense. So, I guess my argument for good old-fashioned ADO.NET would be in the case where you manipulate and modify large datasets, in which case you will benefit from the direct access to the backend.
Another case, of course, is where you have to access a legacy database that is already guarded by stored procedures.
ASP.NET Data Source Controls
Are these something altogether different or just a layer over standard ADO.NET?
- Would you really use these if you had a DAL or if you implemented LINQ or Entities?
NHibernate
Seems to be a very powerful and powerful ORM?
Open source

Is there a way to change password to value same as the previous password?
when I try this:
[mrbean@wwwserver ~]$ passwd
Changing password for user mrbean.
Changing password for mrbean
(current) UNIX password:
New UNIX password: -- here i typed same password
BAD PASSWORD: is too similar to the old one.
I need to change upgrade the PHP version to at least 5.2.0 for my new magento OS Commerce installation, but would it mess up my current store which runs on 4.4.9 (PHPCart)?
The real question is, can I upgrade without harming the old cart?
I try to move my old logfiles to a yyyy\MM\dd folder structure by
Get-ChildItem . -Recurse -Include *.log |
Move-Item -Dest {"D:\Archive\{0:yyyy\\MM\\dd}\{1}" -f $_.LastWriteTime, $_.Name} -Force
but i get a path-not-found error.
update
I suspect the problem originates from the fact that the source path contains Program Files.
sub question: Could the same be done without Get-ChildItem?
I'm trying to learn the Microsoft data / service stack. I want to build a database in SQL Azure and expose it to a c# client application.
I've never worked with any SQL database technology.
Looking online, everything just seems so confusing -- too many technologies, hard to tell what's new vs what's old.
What's the latest technologies to look at, and what (books?) should I be reading?
I'm working with an old windows app in visual studio 2005. A webserviced referenced in the original app has 2 functions and when i peak inside the auto-generated reference.cs file I notice a couple of other functions to allow async calls have been geenrated i.e. BeginWhateverFunctionNameIsCalled and EndWhateverFunctionNameIsCalled.
My problem is that I've created a new windows app and added the same web references but the Begin and End functions are not generated in my reference.cs proxy class. Anyone know whats going on?
I have multiple Java projects in Eclipse. I would like to reuse some classes in my new project from my old project. What is the best way to do that in Eclipse?
I.e. is it possible to add another "project folder" to the build-path for my new project?
Assume,
void proc(CString& str)
{
str = "123";
}
void runningMethod()
{
CString str="ABC";
proc(str);
}
I understand that at the exit of runningMethod str will be deallocated automatically; in this case, how does C++ delete the old data ("ABC")?
Thanks,
Gil.
Hi,
I have over 2000 HTML files that are now in Wordpress blog. I have the URL Map of Old_file.html and new wordpress URL.
I want 301 redirect but don't want to add 2000 lines to htaccess. Can you please suggest how to accomplish this using PHP so that when there is a request for old url, the php script should lookup into the database and redirect(301) to the new URL ?
Thanks.
I have a window I'm opening with a Javascript function:
function newwindow()
{
window.open('link.html','','width=,height=,resizable=no');
}
I need it that once the new window opens that the focus returns to the original window.
How can I do that?
And where do I put the code - in the new window, or the old one?
Thanks!
How can I go about redirecting my old URLs which would have been: http:// blah.com/some/post/name
to the new URLs which would be: http:// blah.com/new/some/post/name
Is this even possible?
I don't want to simply redirect any requests for the blah.com domain to blah.com/new
I want to make sure the subpath is still attached to the redirect
Hi
In my View I'm using jquery ui datapicker.
So I need initiate it with code like this

$('#elementID').datepicker({
});
});
In my View
<%= Html.TextBoxFor(m=m.StartDate) %
In old ASP.NET I may use

What is about retrieving element Id of Strongly Typed ASP.NET MVC HTML Helper?
Is is possible?
I have started a new project in .NET which uses some old system's datababase in MySql. The data stored in mysql is periodicaly transfered to MS Sql on which our system works.
I need to authenticate users with their login and password. User's passwords are stored as hash generated by OLD_PASSWORD function from mysql.
Is there any way to generate such hash using Ms Sql or .NET ?
Exit-games make a network library product called photon, and they have and actively develop a limited mmo demo. Rather than shooting off json or XML, etc. saying "MovePlayer" (with associated params), they nut that message down to a 2 digit int, via an enum - something like Operations.MovePlayer. There's no denying that a 2 digit int is smaller than a longer string, however I really hate the idea of statically burning each and every message into an enum.
Would there be an alternative way to have a MessageID property assign itself a unique 2 digit int based on a lookup table or something? Has anyone dealt with this kind of thing before?
