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'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 general app model, after was released any body can do plug-in for it, this plug-in can determine new db parts which merged with my general db. After some time i 'll release new db version^ and plug-in writers may release new version of their dbs. So i need map old version of merged db into new version. How i can do this?
Is there a way to force QtCreator to recompile all the resources (images / qss files) i have specified in my qrc file every time i build the project?
Currently if i change some styles in my qss file but dont remove the file and re-add it to the qrc file the old version of my qss file is used.
Thanks.
Who can give me a link for the operator= of vector in MSDN?
Why I can only find operator[]?
If operator= is just something default, like copy everything in A to B, how this following code works?
vector<double> v(100,1);
v = vector<double>(200,2); // if operator= is just a trivail version, how to make sure the old v get cleared?
Im building an automatic refreshing comment section for my website using jQuery .load. So I am using a javascript 'setTimeout' timer to check for new comments.
But after doing some stuff like changing comment pages or deleting (all using ajax), a few old timers keep running, even though I used clearTimeout before loading new ajax content.
Is there some way to clear ALL javascript timers when I load new ajax content?

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

I tried adding my own fields with names like _myappvar and _myotherappvar to documents to distinguish them from data fields. At first it worked but at certain points futon complains.
What is the right way to go?
I am using couchdb 0.9.0, this may be old, butI will not be able to upgrade in this iteration.
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.
Hi guys, do you have any idea on how to have getdate() function in enterprise postgresql? I upgraded to EDB-PSQL, and now when I tried to restore old data from the free PSQL, it returns error on some tables since there is no getdate(). I believe this should automatically be created upon creating new database? But it didn't. :( Only now() function. Can I create the function instead? Help!
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
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.

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?
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!
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?
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.
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,

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 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 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?
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.
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.
Hi,
I have done few changes and unable to get my images resolved correctly.
Old = http://www.domain.com/dir/images/*.jpg

Doesn't work, any pointers on how to get to work the images resolved correctly ?
Thanks
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?
