Each seems to provide essentially the same thing, as they each provide a simplified wrapper over the (very obtuse) standard W3C DOM APIs.

I've researched for introductions to Assembly and to me they go much faster than they should. They jump straight into registers and operations without explaining what exactly they are, and why they matter.

void PreventForwardNavigation(object sender, NavigatingCancelEventArgs e)

{
e.Cancel = true;
}

However, if I place it in the Loaded event handler for the Page, then it is called every time the page is navigated to. If I understand right, that means I'm handling the same event multiple times.
Am I ok to add the same handler to the event multiple times (as would happen were I to use the page's Loaded event to hook it up)? If not, is there some place in between Initialized and Loaded where I can do this wiring? | .net | wpf | navigation | null | null | null | open | When is NavigationService initialized?

On ATI cards, such as in the iMac, it draws to the back buffer. The width and height are correct (and 800x600 buffer) and m_PixelBuffer is correctly filled with 0xAA00AA00.
My best guess so far is that there is something amiss with needing glWindowPos set. I do not currently set it, and when I get GL_CURRENT_RASTER_POSITION I noticed that the default on the ATI card is 0,0,0,0 and the Intel it's 0,0,0,1. When I set the raster pos on the ATI card to 0,0,0,1 I get the same result as the Intel card, nothing drawn to the back buffer. Is there some transform state I'm missing?

I thought about the obvious ways of preventing such attempts (public/private key encryption, for example), but I've figured out reasonably simple ways hackers could circumvent all of my ideas (extracting the private key from the binary and thus sending fake encrypted scores, for example).

Loading significant chunks of that data can take some time and we have implemented various measures to reduce the amount of data that has to be searched and loaded for larger queries, such as storing larger granularities for queries that don't require a high resolution (time-wise).
When searching for data in our backup archives, where the data is stored in bzipped text files, but has basically the same structure, I noticed that it is significantly faster to untar to stdout and pipe it through grep than to untar it to disk and grep the files. In fact, the untar-to-pipe was even noticeably faster than just grepping the files (i. e. discounting the untar-to-disk).
This made me wonder if the performance impact of disk I/O might be much heavier than I thought. So here's my question: <b>Do you think putting the data of multiple rows into a (compressed) blob field of a single row and search for single rows on the fly could be faster than searching for the same rows via the table index?</b>
For example, instead of having this table
CREATE TABLE data ( `source` INT, `type` INT, `timestamp` INT, `value` DOUBLE);
I would have
CREATE TABLE quickdata ( `source` INT, `type` INT, `day` INT, `dayvalues` BLOB );
with approximately 100-300 rows in data for each row in quickdata and searching for the desired timestamps on the fly during decompression and decoding of the blob field.
Does this make sense to you? What parameters should I investigate? What strings might be attached? What DB features (any DBMS) exist to achieve similar effects?

However, I need to be able to test for the table in case the table gets dropped but not created (i.e. when someone stops the DTS package just after it starts -roll-eyes- ). If I were doing this in the SQL database I would just do:
IF (EXISTS (SELECT * FROM sysobjects WHERE name = 'Table-Name-to-look-for'))
BEGIN
drop table Table-Name-to-look-for

But how do I do that for an Access database?

My problem is that, as these services run, they start to consume more and more CPU time through each iteration of the loop, even if there is no meaningful work for them to do (ie, they're just idling, looking through the database for something to do). When they start up, each service uses an average of (about) 2-3% of 4 CPUs, which is fine. After 24 hours, each service will be consuming an entire processor for the duration of its loop's run.

Our current solution is to restart the services once a day (they shut themselves down, then a script sees that they're offline and restarts them at about 3AM). But this is not a long term solution; my concern is that as the services get busier, restarting them once a day may not be sufficient... but as there's a significant startup penalty (they all use NHibernate for data access), as they get busier, exactly what we *don't* want to be doing is restarting them more frequently. | c# | nhibernate | windows-services | .net-1.1 | null | null | open | Windows Service Increasing CPU Consumption

I am looking for some JavaScript based component to be used as a course scheduler which would be a cross between Google Calender and the login time . I do not know if the right term for this is <i>Course Scheduler</i> but I shall desribe this in more detail here.
<b>Course Scheduler</b>
The widget would be used to enter date and times of a course, as an example if I run a programming course 3 days a week on Mon, Tue and Wed every 7:00 am to 9:00am, 2 hours every day from 1st September to 30th November. I could answer various questions and the course data would be displayed in the calender. It would also allow for non pattern based timings where each week is different from the other week etc.
<b>Question</b>
So would I end up creating something from scratch? Would it be sensible to use Google Calender API for this? I did a Google search for some widgets, but I believe I need better keywords, as I could not find anything close to what I am looking for. Any tips? Commercial libraries would also work for me.

I can't get it to work, but I'm not sure if I've done something wrong or if this functionality isn't yet available.
I've been trying to use the ItemizedOverlay and OverlayItem classes. Their intended purpose is to simulate map markers (as seen in Google Maps Mashups) but I've had problems getting them to appear on the map.
I can add my own custom overlays using a similar technique, it's just the ItemizedOverlays that don't work.
Once I've implemented my own ItemizedOverlay (and overriden createItem), creating a new instance of my class seems to work (I can extract OverlayItems from it) but adding it to a map's Overlay list doesn't make it appear as it should.

MyItemizedOverlay markers = new MyItemizedOverlay(r.getDrawable(R.drawable.icon));
overlays.add(markers);
OverlayItem oi = markers.getItem(0);
markers.setFocus(oi);
mapView.postInvalidate();
}

public class MyItemizedOverlay extends ItemizedOverlay<OverlayItem> {

1. Contract approach.
When a method does not do what it says it will do in the method header, it will throw an exception. Thus the method "promises" that it will do the operation, and if it fails for some reason, it will throw an exception.
2. Exceptional approach.
Only throw exceptions when something truly weird happens. You should not use exceptions when you can resolve the situation with normal control flow (If statements). You don't use Exceptions for control flow, as you might in the contract approach.
Lets use both approaches in different cases:
We have a Customer class that has a method called OrderProduct.
contract approach:
class Customer
{
public void OrderProduct(Product product)
{
if((m_credit - product.Price) < 0)
throw new NoCreditException("Not enough credit!");
// do stuff
}
}
exceptional approach:
class Customer
{
public bool OrderProduct(Product product)
{
if((m_credit - product.Price) < 0)
return false;
// do stuff
return true;
}
}
if !(customer.OrderProduct(product))
Console.WriteLine("Not enough credit!");
else
// go on with your life
Here I prefer the exceptional approach, as it is not truly Exceptional that a customer has no money assuming he did not win the lottery.
But here is a situation I err on the contract style.
Exceptional:
class CarController
{
// returns null if car creation failed.
public Car CreateCar(string model)
{
// something went wrong, wrong model
return null;
}
}
When I call a method called CreateCar, I damn wel expect a Car instance and some lousy null pointer, which can ravage my running code a dozen lines later. Thus I prefer contract to this one:
class CarController
{
public Car CreateCar(string model)
{
// something went wrong, wrong model
throw new CarModelNotKnownException("Model unkown");
return new Car();
}
}
Which do style do you use? What do you think is best general approach to Exceptions?

I want to copy them to three new files (foo_*.txt).
- foo_x.txt
- foo_y.txt
- foo_z.txt
Is there some simple way to do that with one command, e.g.
<code>cp --enableAwesomeness template_\*.txt foo_\*.txt</code>

I came across the [Design by Contract][1] approach in a grad school course. In the academic setting, it seemed to be a pretty useful technique. But I don't currently use Design by Contract professionally, and I don't know any other developers that are using it. It would be good to hear about its actual usage from the SO crowd.

--works in 2k5, not in 2k
create view foo as
SELECT usertable.legacyCSVVarcharCol as testvar
FROM usertable
WHERE rsrcID in ( select val
from dbo.fnSplitStringToInt(
usertable.legacyCSVVarcharCol, default) )
--error message:
Msg 170, Level 15, State 1, Procedure foo, Line 4
Line 25: Incorrect syntax near '.'.
So, legacyCSVVarcharCol is a column containing comma-seperated lists of ints. I realize that this is a huge WTF, but this is legacy code, and there's nothing that can be done about the schema right now. Passing "testvar" as the argument to the function doesn't work in 2k either. Passing a hardcoded string as the argument to fnSplitStringToInt works in both 2k and 2k5.
Does anyone know why this doesn't work in 2k? Is this perhaps a known bug in the query planner? Any suggestions for how to make it work? Again, I realize that the real answer is "don't store CSV lists in your DB!", but alas, that's beyond my control.

$query = $mysqli->query('SELECT * FROM `people` ORDER BY `name` ASC LIMIT 0,30');
// Example 1
$query = $query->fetch_assoc();
// Example 2
$query_r = $query->fetch_assoc();
$query->free();
Now if I'm right Example 1 should be more efficient as `$query` is `unset` when I reassign it which should free any memory associated with it. However there is a method (`MySQLi_Result::free()`) which frees associated memory - is this the same thing?
If I don't call `::free()` to free any memory associated with the result but `unset` it by reassigning the variable am I doing the same thing? I don't know how to log this sort of thing - does anyone have some ideas? | php | memory | mysqli | null | null | null | open | Using MySQLi - which is better for closing queries
