The environment is PHP 5.2.17 on Apache/2.2.22 (Unix) and the files have been uploaded from a windows machine. Currently, I've only tested 2-3 images by hardcoding them into a test php file, do you think it would be different if the filenames were pulled from a database query?

I'm only running SQL Express at the moment so can't jump into sql profiler until my download completes, so until then, is there something that stands out in my following LINQ that is going to cause a massive slow down?
Below is a summary of what gets executed. The hold up is of course on the ToList call, and takes a good 30 seconds. I use this code for all my grid views, and only one has the hold up on it. MyGridView is a sql view and in the problem data takes only 2 seconds to execute and return all 16417 records through Sql Management Studio. Finally, it only takes this long when I request pages near the end of the data, so I am assuming it is some how related to the Take and Skip implementation.
private void Demo()
{
// using LINQ To Entity...
using (var entities = new MyEntities())
{
int page = 1641;
int pageSize = 10;
IQueryable<MyGridView> results = entities.MyGridView;
results = results.Where(r => r.DeletedDate == null);
var resultCount = results.Count();
results = ApplyPaging(results, page, pageSize);
// On the problem data, ToList takes a good 30 seconds to return just 10 records
var resultList = results.ToList();
}
}
private IQueryable<T> ApplyPaging<T>(IQueryable<T> data, int currentPage, int pageSize)
{
if (pageSize > 0 && currentPage > 0)
{
data = data.Skip((currentPage - 1) * pageSize);
}
data = data.Take(pageSize);
return data;
}
Anything jump out as being bad, wrong, dangerous? When I get a copy of profiler installed I'll try and go through the generated sql and post if I find any hints there.

The users spend all day using the tablets and travel a lot throughout the day.
The time when the users complete these tasks is crucial to the reports and we have had several occurrences where we can't rely on the device time.
1. The user sometimes manually sets the time to something different on the device in order to look like they have done more work - this happens more than we expected
2. When relying on the time set to 'automatic', the time sometimes jumps around as the users travel between networks
3. When the tablet is initially switched on, sometimes the device time is set to 1970
I have a webservice to get the server time which is not currently used because we can't rely on the users having internet connection because they generally don't have any connection at all due to the nature of the work. However, they sync the data everyday usually, or at least once every few days.
I'd like to create something that gets the server time and counts the time from then on and the app would use this time. Any time they connect, this time will be updated, just to make certain the time is synced. Does anyone have any suggestions as to the best way to do this? Bear in mind that the time that we send up is crucial - it could be the case that if misreported on several occasions, someone could lose their job.

I have an application which records information using a tablet which is sync'ed to a server where reports are then run on the results. The users spend all day using the tablets and travel a lot throughout the day.
The time when the users complete these tasks is crucial to the reports and we have had several occurrences where we can't rely on the device time.
1. The user sometimes manually sets the time to something different on the device in order to look like they have done more work - this happens more than we expected
2. When relying on the time set to 'automatic', the time sometimes jumps around as the users travel between networks
3. When the tablet is initially switched on, sometimes the device time is set to 1970

Hello,
I have a simple web page with two text input and one file input. Now, for the form to be sent, both the text inputs and the file input have to be filled. With Synapse, I know how to upload a file (*HttpPostFile*) and how to post data (*HttpMethod*). However, I don't know how to do both.
After looking at the source code of Synapse, I guess I have to "format" my data with boundaries or something like that. I guess I should have one boundary for my input file another boundary for my "normal" POST data. I found an article on the subject, but it's about sending email attachments. I tried to reproduce what they said with Synapse, with no results.
Code for *HttpPostFile*:
function HttpPostFile(const URL, FieldName, FileName: string;
const Data: TStream; const ResultData: TStrings): Boolean;
var
HTTP: THTTPSend;
Bound, s: string;
begin
Bound := IntToHex(Random(MaxInt), 8) + '_Synapse_boundary';
HTTP := THTTPSend.Create;
try
s := '--' + Bound + CRLF;
s := s + 'content-disposition: form-data; name="' + FieldName + '";';
s := s + ' filename="' + FileName +'"' + CRLF;
s := s + 'Content-Type: Application/octet-string' + CRLF + CRLF;

Whenever I attempt to build a new controller and views w/ repositories, I get a MethodInvocationError during scaffolding. Specifically, System.Management.Automation.MethodInvocationException calling "Execute" with "5" arguements. Object reference not set to an instance of an object. According to the stack trace, this is happening at the NuGet.PackageExtensions.GetFiles() method. Of course, the final statement in the stack dump is "You may need to upgrade to a newer version of MvcScaffolding", but I've determined that this is appended to the end of all the errors. I'm currently using v1.7 of the MvcScaffolding package, which is the latest. Anyone have any thoughts on why this is happening, and better yet, how to get around it?

If you are not sure what Ken Ken is, it is similar to Sudoku in the way that there can be no duplicated integer values in a row or column.
I am trying to fill a 2D Array with numbers from an Array List that is created for every new row. I make checks to see whether or not the number taken from the Array List does not match any numbers within its own row and column.
When I run my code I get an "Index Out Of Bounds" exception when I try removing the integer value from the list. I'm not sure why this is happening because I think I am getting the right element.
Here is my code:
`GRID_SIZE = 4;`
`grid = new int[GRID_SIZE][GRID_SIZE];`
private void populateGrid() {
for (int row = 0; row < GRID_SIZE; row ++) {
// Creates an array of values from 1 to grid size.
for (int i = 0; i <= GRID_SIZE; i++) nums.add(i);
for (int col = 0; col < GRID_SIZE; col++) {
while (nums.size() > 0) {
// Gets a random number from the Array List
int ranNum = nums.get(numGen.nextInt(GRID_SIZE));
// Checks to see if the number is placeable.
if (canPlace(ranNum, row, col)) {
// Places the number in the 2D Array
grid[row][col] = ranNum;
break;
} else {
// Removes duplicate element from the Array List.
nums.remove(ranNum);
}
}
}
}
}
private boolean canPlace(int ranNum, int row, int col) {
for (int i = 0; i < GRID_SIZE; i++) {
// Checks if the specified number is already in the row/column.
if (grid[col][i] == ranNum) return false;
if (grid[i][row] == ranNum) return false;
}
return true;
}
I have a few questions about this:
First of all, why am I getting the error that I am?
Secondly is there anything better to use than a 2D Array for the grid and the way I place my numbers?
Lastly, am I using the break correctly?

All the pages (units) are saved in single HTML files, which are no problem to display.
What gives me more problems is the navigation, as the manual structure is stored in a 1MB XML file:
<VIEW>
<ITEM>
<FOLDER>
<FOLDER>
<ITEM>
<ITEM>
</FOLDER>
<FOLDER>
<ITEM>
</FOLDER>
<ITEM>
</FOLDER>
<FOLDER>
<FOLDER>
...
As you can see, the manual structure is similar to the one of a file system. And this is my current problem.
My target is to have a ListView, which only shows always one level of the structure, in which you can navigate forth and back. But I have problems with performance and currently I don't know which is the best solution for this problem.
I already checked two approaches:
- DOM: it takes ages to load the XML and parse it... (16 seconds for a standard size manual)
- using SAX (this is pretty complex for me, as I have to parse the XML recursively)
Which is the right way in terms of performance? Do I even have to parse the XML document in advance or can I parse it each time I change the navigation level?

Then there would be a grid (I am using Telerik MVC grid). I want to add OrderItems to this grid. I was thinking of having s small form above the grid with its own submit button. I can submit using ajax and refresh the grid using ajax.

The following is the nginx configuration i am using:
server {
root /home/test/public;
index index.php;
access_log /home/test/logs/access.log;
error_log /home/test/logs/error.log;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to index.html
try_files $uri $uri/ index.php;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
# pass the PHP scripts to FastCGI server listening on unix socket
#
location ~ \.php($|/) {
fastcgi_pass unix:/tmp/phpfpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}
I am able to get the homepage but am having problem with the inner pages. The inner pages display an "Access denied". Possibly the rewrite is not working, in effect I think its querying and trying to execute php files directly instead of going through the concrete dispatcher.
I am totally lost here.
Thankyou for your help, in advance. | 0 |

}
The **main optimization** will come by running the instructions numbered 1-8 in parallel using **VMLA** instruction in NEON.
1. We may do that by loading array c[8] into registers q0 and q1 and loading array src[256] into registers q2 and q3.After this we use VMLA,VADD,VPADD to get the result in the variable sum.
2. The **problem being faced** is **how to load the elements of array src** (as src[0],src[4],src[8] and so on)since the only way i know how to load an array is by [%1]! which only loads an array sequentially(as src[0],src[1],src[2] and so on).
Also **how may the pointer src be incremented by 2** in instruction 9?

Reasons for rejection:
------------
**2.16**
**We found that your app uses a background mode but does not include functionality that requires that mode to run persistently. This behavior is not in compliance with the App Store Review Guidelines.**
**We noticed your app declares support for audio in the UIBackgroundModes key in your Info.plist, but no audible content is played when the application is in the background. While your intention may have been to provide this functionality, at the time of review, we were not able to play background audio for your app.**
**As indicated in the iOS Application Programming Guide:
"This key is intended for use by applications that provide audible content to the user while in the background, such as music-player or streaming-audio applications."
Therefore, it would be appropriate to provide audible content to the user while the app is in the background or remove the "audio" setting from the UIBackgroundModes key.**
--------------------
In the v 1.0 which has been accepted the required background mode "App audio plays" was already enable.
When i launch one sound of my app the sound is played and i when click on the lock screen the sound continues to be played in background.
In the new version (v1.1) i added the function which detects when i push the button Home of the iphone. If the button home is pressed so the sound is paused.
When i try on my device it's run correctly and without bug.
So I don't understand exactly what is the problem with my app?
In advance thanks,

When I connect using the code I'd use to connect to a stand alone instance the message is not received by the cluster.
I believe it is using the default 7676 port. When the IIOP port is changed to use port 23700 which is the one the cluster (DAS) is using I get a connection refused exception as it is trying to connect to localhost:27676. At least it's the right port.
WARNING: [C4003]: Error occurred on connection creation [localhost:27676]. - cause: java.net.ConnectException: Connection refused: connect
I've also updated the following values in node config file (domain.xml) to remove references to localhost. jms-host and node-host values.
I had this issue before with a stand alone instance and it was resolved by adding entries to the /etc/hosts file. However, this does not seem to resolve the issue.
I also have all server instance IPs in the hosts file.
Am I missing something very basic here?
Any help would be greatly appreciated.

In general, in the event-driven C Webkit-GTK API there are a lot of events which may relate to the idea of when some document is finished "loading". The problem is the [documentation][1] is pretty sparse, and the idea of "finished loading" isn't necessarily clear, because it can refer to a lot of things. Does "finished loading" mean that the document is finished *downloading*? That it's finished creating the DOM tree? That it's finished downloading including *all* other resources (like CSS, JS and image files?)
Relevant signals are `signal::notify::load-status`, `document-load-finished`, and `resource-load-finished`.
The `load-status` signal fires everytime the load status changes, so you need to manually call `webkit_web_view_get_load_status` and check the status each time. Even so, when the status finally is `WEBKIT_LOAD_FINISHED`, I'm not sure what that means - does it mean WebKit is done *downloading* the resource, or that it's finished creating the DOM tree, or what?
Question:
What is the difference between the various "finished" signals, and is there any signal that is equivalent to the standard Javascript DOM event `window.onload`?

So I'm trying to create an application that has a pop up window with a pointer/line coming from the child window to a particular place in the parent window. I achieved this like so;
<Border Name="brdr" Margin="40,0,0,0" >
//Content
</Border>
<Line
Name="Pointer"
X1="0"
X2="40"
Y1="55"
Y2="50"
StrokeThickness="2"
Stroke="Black"
></Line>
Notice the 40 left `Margin` on the border that makes the window larger than it appears so that the `Polygon` sticks out to the left and points to the parent window (If there's a better/cooler/more elegant way of doing this, I'm all ears).
So that worked fine but now I want the pointer to be dynamic. As in, if the child window gets dragged the pointer must scale relatively to the parent window's location. I.e. it must appear as if the two windows are attached via the line. Now my plan was to record the point the child window opens on (because it opens relative to the parent window, it's correct when it initialises) and then use the difference between this and the new location point (after dragging) to find the new points that the line should be going to. My code probably says it better than I ever could...
private void Window_LocationChanged(object sender, EventArgs e)
{
if (this.IsLoaded)
{
brdr.Margin = new Thickness(Math.Abs(this.Left - WinLeft) + 40, Math.Abs(this.Top - WinTop), 0, 0);
Pointer.X1 = Math.Abs(this.Left - WinLeft);
Pointer.Y1 = Math.Abs(this.Top - WinTop) + 55;
Pointer.X2 = Math.Abs(this.Left - WinLeft) + 40;
Pointer.Y2 = Math.Abs(this.Top - WinTop) + 50;
}
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
WinLeft = this.Left;
WinTop = this.Top;
}
As you can see I have to set the window margin so that it extends to the old position (using absolute values to make sure the window can go both right and left). Then I reset the `Line` coords to the new values. All these values are calculated, like I said, by comparing the opening window coords to the current coords.
My problem is, this isn't right. Would be very impressed to see someone able to figure this out. | c# | wpf | math | coordinates | parent-child | null | open | Line Joining Parent to Child Window

**I am attempting to theme a Drupal webform which has multiple fieldsets. The idea is to stack the fieldsets on top of each other. A fairly simple CSS issue of positioning relatively and absolutely - but it goes very wrong as the containing div collapses instead of maintaining it's shape.**
You can see the problem at **http://164.177.146.240/eventbooking5/node/6**. I set the background-color of the fieldsets to green.
The containing border has a red border and is positioned relatively.
**When the fieldsets are positioned absolutely, they stack as I expect but the containing DIV collapses and compromises the rest of the sites styling**
I really would appreciate some help.

ie. **User** chooses **Age** in DropDownList, this should produce **AgeFrom/AgeTo** DropdownLists on **SearchCombination** page and Day/Month/Year DropDownLists on **Customer** page.

That worked just fine until I started report development. Crystal Reports has no ability (that I can detect) to do a time zone conversion so I need to do the conversion within SQL before passing the value to the report.
SQL Server appears to have a much more limited ability to convert datetime values. The only function I see is SWITCHOFFSET. The problem with this function is that it is not daylight-savings aware which seems to be a major flaw. In asp.net, I can pass a datetime value with a time zone and it will automatically convert it to UTC time, taking account of any needed daylight savings time adjustments.
In SQL though, instead of saying something like
SWITCHOFFSET (SomeDate,"Eastern Time"),
I now have to say
SWITCHOFFSET(SomeDate, "-4:00").
But what happens if I'm pulling data from a table and I ask for all of the data for March, the month when daylight savings starts? No matter what, some of it will be incorrect. I can either say -4:00 or -5:00 but obviously, not both.
Is there some other function to adjust for this as, frankly, it seems SWITCHOFFSET is half baked if it doesn't know how to do a daylight savings conversion. | sql-server | timezone | null | null | null | null | open | SQL Server 2008 time zone conversion

The function presently returns the 10 values as a `RECORD` type.
This solution makes downstream processing more difficult. I found an excellent [answer][1] which explains how to split the `RECORD` values into columns. This is further complicated though if I want to also include the key value in the `SELECT` results, as the key is not returned in the `RECORD`. I could include it of course, but what if I wanted another column or a column from another table?
**Question:** In this case, would it be better for the function to create and populate a table? Or to return a `TABLE`? I'm sure this is a common enough concept: store the results or calculate them on the fly every time they are needed? I'm starting to think that creating a table would be the best solution because all those data are there for easy querying and further analysis later.

- all slide previews have the clean-URL in a href
This works fine, even without JavaScript the user can see every slide (without the animation and involving a page load of course).
The question is: A search engine sees all links. But basically all links have the same content. Can this cause the page rank to decrease? And if so, what would be the best solution to this problem? I only can image a solution like this:

Heres the thing. I have a (paid for) shopping cart, which I am currently in the process of jazzing up with jquery and css and whatever else to make it look and work much nicer than it currently is.
Anyway. In order to use their database and their functions etc, I need to include their file at the beginning of the webpage. I have put it in a
<div style="display:none;">
But of course any output is still written to the browser. its not alot, but I would prefere to have NO div and NO output, but i still want it to perform it's calculations. Its 5000 line PHP file and Its too complicated to go through and edit out the bits I dont want.
is there a clever way, that I can include the file but specify if I want anything written to page when including it?
I knows it's a bit of a bodge, I hope i've explained myself, if anyone can help please let me know.
