the issue i am facing is, when i open the dialog the second time, the OK and Cancel events are not triggered.
i have a feeling that the issue is silly, sorry and thanks in advance.

A part of the form uses radio buttons to choose an attribute. I then use [jQuery UI to display the buttons][1], like so.
<head>
<script type="text/javascript">
$(document).ready(function() {
$("#typeRadios").buttonset();
});
</script>

<input id="character_chartype_a" name="character[chartype]" type="radio" value="B" /><label for="character_chartype_b">B</label>
</div>
</body>
This all works fine. I click a button, and then when the form is submitted the attribute is saved correctly.
The problem is, I need to be able to click one of the buttons programmatically. At the moment, I'm doing this:
// data.chartype = a
$("label[for='character_chartype_"+data.chartype+"']").click();
This works in the sense that visually the button appears clicked, but when the form is submitted, the attribute isn't saved. What is causing this behaviour? Thanks for reading.

A field of a class also can be either public or package-private. These "statuses" have the same meaning. If something is package-private it is visible only within the same class. It is public it is visible from everywhere (from any package).
What is not clear to me is how these statuses interplay. In particular I have interest in the following two cases:
1. The class is public but its field is package private. Will be this field visible only from within the package?
2. The class is package-private and it has a public field. Where will be sing this field?

I would have about 20-30 minutes, without projector or anything. (They have an old computer though, which by its look may be a 486, and I am not even sure if it's functioning.)
My research turned up excellent earlier threads, with lots of good tips:

> [Career Day: how do I make “computer programmer” sound cool to 8 year olds?][2]

Explain ? | Although it's true that some recursive-nameserver configurations are (sloppily) referred to as "caching", e.g., by RHEL/Fedora/CentOS, that's a really bad name for that function -- because caching is orthogonal to recursion.
Theoretically, you could write a nameserver that does recursive service but doesn't cache its results. (That would be a bit perverse, and I don't know of any.)

1. I recently installed Ruby 1.9.2 on my Mac (running Snow Leopard 10.6.4) and I haven’t been able to figure out how to get Terminal to use the new Ruby as a default, rather than the factory-installed Ruby 1.8.7. The old Ruby 1.8.7 is located in my ~/usr/bin/ruby directory while the new Ruby 1.9.2 is in ~/usr/local/bin/ruby. Someone said that I need to put the new version of Ruby's directory in the PATH prior to the old version's directory so that the system looks there first - is this correct? If so, can anyone provide step by step instructions on how to do this?
2. I’ve created a new directory but can’t seem to figure out the correct way to add that directory to my PATH using the Terminal bash shell. I tried using the instructions that I found here (http://www.macgasm.net/2008/04/10/ad...thin-terminal/) twice but they didn't work for me. The directory containing my program ("Ruby_Programs") shows up in the PATH but when I try to run "ruby newprogram.rb" from the command line it results in ":ruby: No such file or directory -- newprogram.rb (LoadError)". The file definitely exists and is a functional Ruby program. I did change the name of the directory to "Ruby Programs" and then back to "Ruby_Programs" - could that have somehow caused this problem?
Any help would be greatly appreciated. Here is my current PATH:

know the password of root(or if we forgot our password)
This is the method...
1. At the boot loader menu, spam "e" to edit the kernel
2. Select the second line (it begins with the word kernel)
3. Edit the line by pressing "e"
4. At the end of this line, add the word "single", without quotes
5. Exit out of this line by pressing enter
6. Boot off of the kernel while having that line highlighted by pressing "b"
7. It will boot into single user mode
8. Type "passwd", without quotes, and it will prompt you for a new password
9. Enter your new root password and login
suppose if any normal user change the root password with this method then other users will be affected (if server is hacked)...
then how is linux is secure ???

1. Is COP and the "Camera" the same thing? Which in turn refers to the "User" looking at the screen?
2. Can someone please explain to me the relation between the Projection Perspective and the Viewport if there is one? Because at the moment to me they seem to be the same thing. Or is the PP the Window which is then scaled to fit the viewport?
3. In OpenGL when setting up gluPerspective the zNear value is the distance of the Camera from the Projection Perspective so the combination of the fovy and zNear defines the size of the Window (assuming that the Window == the Projection Perspective and I undestand something :/ ) into the World.
4. When creating a window (only using gl and glu), after you have initalized everything you enter while(!quit) loop that has a render function(this is question is a bit silly), does everything in all case get drawn in this render function which has glBegin() and glEnd(). Lets assume I have a biggish world with lots of features and so on. Does everything that needs to get drawn fit in between those functions such that this Render function can in time become really large?
Sorry I know these questions are really naive but they are a few things that I'm having a bit of trouble understanding.

This was easy, but as a follow on the book asks to add the option to provide a hint to the player to help them guess, firstly as a parallel array (again, no problem) and then as a 2 dimensional array. This is where I'm stuck. My (shortened) array of words is as follows:
const string WORDS[NUM_WORDS] = {"wall", "glasses"};
I need to provide a hint for each of these words but not sure how to go about it. Posting this from phone so extensive googling is not an option!
My parallel array was as follows:
const string HINTS[NUM_WORDS] = "brick...", "worn on head"};
Just need to combine the two.

1- i have two text-boxes for the username and the comment it self, the content of these text-boxes are inserted within a database.
2- retrieve the database content using a dataset to a grid-view.
... everything works great by my question is:
**how do i allow replies to comments like in stackoverflow. like user A says "hi" then user B says "@A - hi". how do i order them so that the reply is below the first comment?**
hope everything makes sense, thanks

I think using stored procedures and views, we can do that. Can any one point me in the right direction on which process will not affect performance to users at the time of responding to questions and at the time of viewing charts.

My app maintains many arrays of items, and as the user drags and drops items around, I need to ensure that my arrays are updated to reflect the contents the user is seeing.
I need to run some code around the time of `Source`.`onDndDrop` ...
If I use `dojo.connect` to set up a handler on my Source for `onDndDrop` or `onDrop`, my code seems to get called too late. That is, the `source` that's passed to the handler doesn't actually have the item in it any more.
This is a problem because I want to call `source.getItem(nodes[0].id)` to get at the actual data that's being dragged around so I can find it in my arrays and update them to reflect the change the user is making.
Perhaps I'm going about this wrong; and there's a better way? | dojo | dnd | dojo-dnd | null | null | null | open | Dojo dnd (drag and drop) 1.7.2 - How to maintain a separate (non-dojo-dnd) list?

Notice the " " around the name key are missing. I believe this is why my `NSPredicate` in my `searchDisplayController` isn't working. Why are the quotes being removed and how would I fix my `searchDisplayController` to work? | 0 |

When I decide to create a strongly-typed View, inside the Add View dialog, the Model class dropdown does not show my ViewModel class.
*For the record, yes I did compile the application before triggering the Add View dialog.*
I believe I have pinpointed the issue but do not know how to fix it.
Below are the repro-steps if anyone cares to reproduce the behavior:
1. In Visual Studio 2010 (sp1), create a new C# asp.net MVC 4.0
(beta) Internet Application.
2. Inside the Models folder, create a new simple class called
“GazouViewModel.cs”
3. Build the application, open the HomeController, right-click the
Index() ActionResult and select Add View…
4. In the Add View dialog, check the “strongly-typed view” checkbox and
in the Model class: dropdown, you’ll notice your “GazouViewModel”
----------------
1. In Solution Explorer, right-click your project and select “Manage
NuGet Packages”
2. Search, find and install the “Bootstrapper.Autofac” package.
3. Rebuild the application and verify if your “GazouViewModel” still
displays inside the Add View dropdown’s dialog.
4. The “GazouViewModel” should still be displaying in the dropdown.
----------------
1. In Solution Explorer, right-click your project and select “Manage
NuGet Packages”
2. Search, find and install the “Autofac ASP.NET MVC4 (Beta)
Integration” package.
3. Rebuild the application and verify if your “GazouViewModel” still
displays inside the Add View dropdown’s dialog.
4. The “GazouViewModel” should still be displaying in the dropdown.
----------------
1. In Solution Explorer, right-click your project and ADD a new class
(Class1.cs) anywhere it doesn’t matter.
2. Make that Class1 implement IAutofacRegistration and implement the
interface.
3. Rebuild the application and verify if your “GazouViewModel” still
displays inside the Add View dropdown’s dialog.
4. The “GazouViewModel” is no longer showing inside the Model class
dropdown.
It appears that as soon as I create a class that implements the `IAutofacRegistration` interface and build the application, I’m no longer capable of viewing my ViewModels in that dropdown.
Can anyone confirm if they are getting the same results as me?
And more importantly, how can one fix this?
**IMPORTANT**: I have tried the exact same steps with an mvc 3.0 application and the exact same behavior occurs…so this is not relevant to the BETA version.
Sincerely
Vince

Hi.
I need to log information about about every step that goes on in the application in an SQL DB.
There are certain tables, I want the log should be related to:
Product - should log when a product has been created changed etc.
Order - same as above
Shipping - same
etc. etc. etc.
The data will be need to be retrieved often.
I have few ideas on how to do it:
1. Have a log table that will contain columns for all these tables, then when I wanna represent data in the UI for a certain Product will do select * from Log where LogId = Product.ProductId.
I know that this might be funny to have many cols, but I have this feeling that performance will be better. In the other hand there will be a huge amount of rows in this table.
2. Have many log tables for each log type (ProductLogs, OrderLogs etc.) I really don't like this idea since it's not consistent and have many tables with same structure doesn't make sense, but (?) it might be quicker when searching in a table that has a lower amount of rows (m i wrong?).
3. According to statement no. 1, I could do a second many-2-many table that will have LogId, TableNameId and RowId cols, and will reference a log row to many table rows in the DB, than will have a UDF to retrieve data (e.g. log id 234 belongs to table Customer at CustomerId 345 and to Product table where productId = RowId); I think this is the nicest way to do it, but again, there might be a huge amount of rows, will it slow down the search? or this is how it should be done, whatcha say?... | sql-server | sql | performance | datastorage | null | null | open | Performance consideration: Spread rows in multiple tables vs concentrate all rows in one table.

Let's say that I want to generate a large data frame from scratch.
Using the data.frame function is how I would generally create data frames.
However, df's like the following are extremely error prone and inefficient.
So is there a more efficient way of creating the following data frame.
df <- data.frame(GOOGLE_CAMPAIGN=c(rep("Google - Medicare - US", 928), rep("MedicareBranded", 2983),
rep("Medigap", 805), rep("Medigap Branded", 1914),
rep("Medicare Typos", 1353), rep("Medigap Typos", 635),
rep("Phone - MedicareGeneral", 585),
rep("Phone - MedicareBranded", 2967),
rep("Phone-Medigap", 812),
rep("Auto Broad Match", 27),
rep("Auto Exact Match", 80),
rep("Auto Exact Match", 875)),
GOOGLE_AD_GROUP=c(rep("Medicare", 928), rep("MedicareBranded", 2983),

But how to wake up a remote pc which is in some remote LAN?In my previous question on WOL, some one said that we cannot turn on the remote pc, because anybody's pc can be easily turned on. Thats true. But we can use a unique password to wake on the system. when i referred wikipedia i got this "**Certain NICs support a security feature called "SecureOn". It allows users to store within the NIC a hexadecimal password of 6 bytes. Clients have to append this password to the magic packet. The NIC wakes the system only if the MAC address and password are correct. This security measure significantly decreases the risk of successful brute force attacks, by increasing the search space by 48 bits (6 bytes), up to 296 combinations if the MAC address is entirely unknown. However any network eavesdropping will expose the cleartext password.Still, only a few NIC and router manufacturers support such security features".**
From this it is clear that WOL implementation with password protection is possible. So why is it not possible to wake on remote pc with secure password?(i need to give an analogy here:assume that u send a msg using ur cell phone to ur friend who is in remote place. the conversation is secure. similarly is there any way to turn my system into a reception point, so that when i send a wake on message, the system gets turned on.?) | java | android | networking | mobile | wol | 05/29/2012 06:43:23 | not a real question | how to wake up remote pc using android phone?

The problem I am having is that whenever I add more image slices than the number of visibleSlices I have listed in the javascript, then they are not on overflow:hidden (as listed in my css.) The extra images slices are placed below the last image slice and the page simply gets longer (because the overflow hidden is not working, i assume.) Additionally, there are supposed to be arrows that appear that the user can click on to scroll to the next (hidden) image slice. While these do appear on the screen, they do not scroll if clicked on or if you are looking at the last image in the set of image slices and click on the next arrow (not knowing it is the last image) then all the images and text go away leaving a blank white page that does not correct itself unless you refresh the page.

Why is the __del__ method being called immediately after the __init__ on the second run?
I am guessing that since the same instance names ('swaroop' and 'kaleem') are being used that it is releasing the original instance and garbage collecting it. But, this seems to be playing havoc with the current population count.
What is going on here?
What is a good way to avoid this sort of confusion?
Avoid the use of __del__?
Check for existing instance names before reusing them?
