knowing what PowerShell can do on a command line I have never learned how to write GUIs with it. Should I?
Or just go back to the good old HTA / VBScript?
I have included gwt-html5-geolocation into my GWT project and was disappointed to find that it doubled up on my number of permutations compiled. Apparently if the browser does not support geolocation API then it falls back to use gears to find out your location. Is there a way to NOT compile a permutation for gears similar to the way you can tell GWT to only compile certain browser permutations? (the geolocation stuff is very much a nice-to-have and frankly if the client is running an old browser then I am happy not to get their location)
Thanks
What are the pros and cons between using the ASP.Net control compared to the old reliable table html implementation.
I know that the asp:Table will end up on the returned page as a html table, and from looking into it so far people are saying its easier to work with the asp:Table in the server side code, but I'd love to hear what the stackoverflow community has to say about the matter.
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!
Are there any tools available for converting a desktop vista machine into a virtual machine to run with MS Virtual PC? I am buying a new workstation and would like to virtualize my old machine onto the new one. I know of the tools for Hyper-V, but i'll be running Win7 on the new machine, not Hyper-V server.
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.
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
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.
Regards,
Android Developer

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 programmatically set the iPad to run the iPhone app at 2x as it is launched (yet keep the iPhone app native). I understand I can create NIB files for each hardware platform, but for ease, I just would rather the app launch as if the user had tapped the 2x on the iPad. Thanks...R.J.
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!
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 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?
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.
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?
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 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
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'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 would like to get started in embedded systems programming but don't know where to start...I have a very solid knowledge of C and C++ and would preferably like to use these languages with the GNU compilers. I have a degree in CS so I have a solid foundation...
I have no clue about what hardware and other resources that I will need...If you work or are knowledgeable in this area, how did you get started and what are some good resource for a beginner?
Thanks.
Herlihy and Shavit's book (The Art of Multiprocessor Programming) solution to memory reclamation uses Java's AtomicStampedReference<T>;.
To write one in C++ for the x86_64 I imagine requires at least a 12 byte swap operation - 8 for a 64bit pointer and 4 for the int.
Is there x86 hardware support for this and if not, any pointers on how to do wait-free memory reclamation without it?
Hi
In my View I'm using jquery ui datapicker.
So I need initiate it with code like this
$(function() {
$('#elementID').datepicker({
});
});
In my View
<%= Html.TextBoxFor(m=m.StartDate) %
In old ASP.NET I may use
tb_startDate.ClientID
What is about retrieving element Id of Strongly Typed ASP.NET MVC HTML Helper?
Is is possible?
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 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 ?
