I have a table server like this;
Model | Brand
-------------------
M4000 | Dell
S4000 | Hp
S3500 | Hp
S6500 | Sun
I want to display different data from the 'Brand' field which means I don't want the second 'Hp' data to display again. How do I do that?
I add textboxes dynamically at runtime. How do I access them later in the program?
Hope this image speaks everything...!!! Need to do this in html + css .. Note: I want the border inside the image.
I have the following regex that checks for a password policy. it is validated to work:
(^([zZ]\d{3})*$)|((?=.{9,})(?=.*?[^\w\s])(?=.*?[0-9])(?=.*?[A-Z]).*?[a-z].*)
I want to use the regex in a bash script to validate a psssword the following way :
echo $password | grep "(^([zZ]\d{3})*$)|((?=.{9,})(?=.*?[^\w\s])(?=.*?[0-9])(?=.*?[A-Z]).*?[a-z].*)"
if [[ $? -eq 0 ]] ; then
This does not work in bash.
My question is :
How do i convert this "pure" regex to a one that work in bash ? which characters do i need to escape, what is the correct way to pass the regex to grep ? are there any other things i need to look out for ?
Thanks
i'm currently experimenting wpf communication between two views of different modules using prism IEventAggregator. publishing module and subscribing module is working fine, for some reason i can't understand why the subscriber UI is not updating.i place a button to display a msgbox at the subscriber module just to be sure that it receives it and it does. and i think i properly implement the INotifyPropertyChanged.
if i place subscribe in subscriber view's code-behind it works as i want it to be....do i do it the wrong way? please correct me. thanks.

I have a single step job that executes a stored procedure. I would like get the date of the last successful job execution time so that I can just update a delta instead of the whole set of data.
Right now I have the job setup to run once every day, so I have a default parameter that if it's null I set it to GETDATE() - 1 so I'm still updating a delta but what I'd like to do is set the date to the last successful execution of the job.
exec dbo.usp_UpdateFrom @LastSuccessfulExecutionTime
Current procedure is something like
CREATE PROCEDURE dbo.usp_UpdateFrom
@FromDate datetime = NULL --would like to pass last successful execution time of the job
AS
IF @FromDate IS NULL
SET @FromDate = GETDATE() - 1
-- do stuff

I have a full screen activity with a ExitText. When edit text is clicked(gets focus) a softkeyboard shows up.
Now, on some samsung android phones(atleast two that I have used), the keypad also has a small "Settings" button which will close your activity and take you to phone's system settings button.
I want to intercept when a user click's this "Settings" soft button and then take some decision before my activity gets pushed back to the stack.
Is it possible? If yes, how?
EDIT
I know that in normal circumstance its a bad user experience and should be avoided. However, I am more interested in the solution (technology side). I am not going to launch an app in the market with such a thing for regular user, so please dont comment saying I should not do this.
I know that developers put such comments in the benefit of the users who are still learning but in some cases, "Its more about HOW to do it?". This scenario is just one of them. Hope nobody takes what I said in a wrong sense. Thnx!

In my current app, I have a list of plays and it is almost universally sorted by the play's name in queries. Currently, it is built simply using DB::select() statements, but while we're doing a lot of refactoring, we want to begin using Kohana's ORM library. The problem comes from the fact that we don't typically sort by the actual play name, but rather a processed version, stripping out articles and the like and sorting by that (so that The Book of Mormon appears with the Bs, rather than the Ts). I don't know how to carry that over into the ORM model definition.
The select code looks like this (abridged):
DB::select(column, column,
DB::expr("CASE WHEN SUBSTRING_INDEX(show_name, ' ', 1) IN ('a', 'an', 'the')
THEN SUBSTRING(show_name, INSTR(show_name, ' ') + 1)
ELSE show_name
END AS show_name_sort")
Is there a way to create a fake show_name_sort column that Kohana will ignore on save, but that I can still use in an order_by call? Or do I just need to create an actual column with the sorted version of the name in it?
I have written a toy WPF application with a Button and an ItemsControl. Each time you click the Button, the string "AnotherWord" gets added to the ItemsControl. Now, the ItemsControl is displayed as horizontally oriented StackPanel with a fixed width (500 pixels). This means that when you click the button a certain number of times (actually six times), the newly added string gets clipped, like this:
"AnotherWord AnotherWord AnotherWord AnotherWord AnotherWord AnotherWo"
This happens when the FontSize is 13; if you lower it to 12.7 then there's room for the sixth occurence of "AnotherWord". My question is: Is there a way to make this adjustment at runtime so that you avoid the overflow?
EDIT:
In the context of the question, the fixed width of the StackPanel is obligatory - we cannot use more than the 500 pixels we have.

I am making an app in which for some reason when I click on a button I have to initiate a new form and at the same time create a new document in the google docs.
I've successfully implemented the above but while the app is busy making creating a new doc at google docs for that time being the newly loaded form's UI freezes.
I read somewhere that this can be avoided if I use multi threading.
So now I wanna ask should I create two threads and in one of them I should place the code for creating new form and in the other one I should place the code to create a document in google doc.
Or I should just create on thread in which I should place the code to create new google doc and let the new form creating code be in the main process??
Also What would be the easiest way to implement threading in an already written code?? Pleaseprovide with some reference reading material if possible.
I was under the assumption that REST was a web service but it seems that I am incorrect in thinking this - so, what is REST?
I've read through Wikipedia but still cant quite wrap my head around it. Why to do many places refer to API's as REST API's?

I am trying to retrieve a file name from the server of the file that has just been uploaded. The problem is that I am getting an undefine index on my php variable below:
Undefined index: fileimagename in /web/stud/xxx/Mobile_app/QandATable.php on line 19
What I am trying to do is that user uploads the form which is done by the php script (imageupload.php), Now when uploading stops it uses the javascript function which is on a seperate page (QandATable.php, same page as the ) to display the message if upload is successful and this would append the name of the file uploaded.
So my question is how can I fix the undefined variable and how can I get the javascript function in the QandATable.php to retireve the file name from imageupload.php?
Below is code which consists the undefined variable and javascript function (QandATable.php):
<?php
session_start();
$fileimagename = $_SESSION['fileimagename'];
?>
<script type="text/javascript">
function stopImageUpload(success){
var fileimagename = <?php echo $fileimagename; ?>;
var result = '';
if (success == 1){
result = '<span class="msg">The file was uploaded successfully!</span><br/><br/>';
$('.listImage').append(fileimagename + '<br/>');
}
else {
result = '<span class="emsg">There was an error during file upload!</span><br/><br/>';
}
return true
};
</script>
Below is php script which uploads the file into the server: (imageupload.php)
<?php
session_start();
if (isset($_POST['fileimagename'])) {
$_SESSION['fileimagename'] = $_SESSION[' $_FILES['fileImage']['name']'];
}
if( file_exists("ImageFiles/".$_FILES['fileImage']['name'])) {
$parts = explode(".",$_FILES['fileImage']['name']);
$ext = array_pop($parts);
$base = implode(".",$parts);
$n = 2;
while( file_exists("ImageFiles/".$base."_".$n.".".$ext)) $n++;
$_FILES['fileImage']['name'] = $base."_".$n.".".$ext;
move_uploaded_file($_FILES["fileImage"]["tmp_name"],
"ImageFiles/" . $_FILES["fileImage"]["name"]);
$result = 1;
}
else
{
move_uploaded_file($_FILES["fileImage"]["tmp_name"],
"ImageFiles/" . $_FILES["fileImage"]["name"]);
$result = 1;
}
?>
<script language="javascript" type="text/javascript">
window.top.window.stopImageUpload(<?php echo $result;?>,'<?php echo $fileimagename;?>');
</script>
Is the right way to use C++11 rvalue-references and move semantics to implement a convenience wrapper for std::reverse()?
template <class BIDirContainer> inline BIDirContainer&& reverse(BIDirContainer a) {
std::reverse(begin(a), end(a));
return std::move(a);
}
The code works in my test case but I am unsure its about performance: should I use && here or is it unneccesary?
This has probably answered somewhere at sometime but the titles I have seen don't connect so here it goes. I have seen python commands that read os.listdir(r".\bootstrapper"). What is the 'r' doing?

i have a table with 2 main columns: name and name without accent.
i would like hibernate to update the 2nd one when 1st one is changed:
@Column(name = "name")
public String getName() {
return this.name;
}
public void setName(String s) {
this.name = s;
this.noAccentName = RemoveDiacritics(name); //remove diacritics from name
}
@Column(name = "noaccent_name")
public String getNoAccentName() {
return this.noAccentName;
}
public void setNoAccentName(String s) {
this.noAccentName = s;
}
This is working but it has an overhead: setter of the name sets object to dirty, and hibernate wants to update it all the time... :(
How can i ask hibernate to update 'noAccentName' when 'name' was changed in a clean way?

I would just want to know, when would i use a Bit-wise AND a normal AND.
I read the a Bit-wise AND is good for applications that has a memory limit.
Which 1 will be the best to use then, overall?
if (true & false)
{
}
or
if (true && false)
{
}
Wouldn't it be better to always use a Bit-wise AND then?
I want to check that my text box is containing special character or not, using java script.
for this i am using following code
function CheckUserId() {
var txt = document.getElementById('<%=TextBox1.ClientID%>').value;
var regexp = "/^[a-zA-Z0-9]+$/";
if (regexp.match(txt)) {
alert("No special character ");
return true;
}
else {
alert("Special character");
return false;
}
}
I am calling this java script function on textbox onblur. TextBox code is following
<asp:TextBox ID="TextBox1" runat="server" onblur="CheckUserId()" ></asp:TextBox>
but it is showing always alert message "special character" .Whats wrong with my code?

Weird behavior of my autocomplete Jquery plugin, the click event show clearly that if input.autocomplete("widget") is visible, that is if it has display:block, then close the widget. But if I change focus from input element to widget itself and lets say scroll a bit, then when i click again on buton , the widget is created again.
My solution wolud be in closing the widget even if focus is transfered to widget itself and not the input element?
Any ideas how to modify this code so it beahaives this way?
this.button = $("<button type='button'> </button>")
.attr("tabIndex", -1)
.attr("title", "Show all items")
.insertAfter(input)
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass("ui-corner-all")
.addClass("ui-corner-right ui-button-icon")
.click(function () {
// when i put breakpoint here, and my focus is not on input,
// then this if steatment is false????
if (input.autocomplete("widget").is(":visible")) {
input.autocomplete("close");
return;
}
// work around a bug (likely same cause as #5265)
$(this).blur();
// pass empty string as value to search for, displaying all results
input.autocomplete("search", "");
input.focus();
});

@ContextConfiguration({"classpath:/META-INF/spring/resources/resource-context.xml", "classpath:/META-INF/spring/services/persistence-context.xml"})
public class UserDaoJpaImplTest {
@Autowired
UserDao userDao;
@Transactional
@Test
public void testCreate() {
User user = new User();
user.addRole(Role.ROLE_USER);
user.addRole(Role.ROLE_ADMIN);
userDao.create(user);
Assert.assertNotSame(user.getId(), 0);
}
the problem is, that jpa (backed by hibernate), is not doing the insert on the USER_ROLES table (it is creating it correctly, with the correct composite PK (ROLE, USER_ID), and FK to user.
I can see in the console, that only a single insert is being done, on the user
Hibernate: insert into USERS values ( )
I assume I am just missing something simple.

I was reading the C++ tutorial and I don't understand why I need to declare dynamic memory, this is what the tutorial says:
Until now, in all our programs, we have only had as much memory available as we declared for our variables, having the size of all of them to be determined in the source code, before the execution of the program.
And then it says that we have to use new and delete operators to use dynamic memory.
However, I seem to be using dynamic memory when declare a pointer, e.g. char* p, for which I have not specified the length of the array of characters. In fact, I thought that when you use a pointer you are always using dynamic memory. Isn't it true?
I just don't see the difference between declaring a variable using new operator and not. I don't really understand what dynamic memory is. Can anyone explain me this?
I have a simple question. I want to run a bat file that should run post build. The bat file takes in to parameters previousVersion and currentVersion (These parameters are entered as Validating String Parameters before the build starts).
This is what I have tried
Execute Windows Batch Command
set v = %currentVersion%
set pv = %previousVersion%
cmd \k "C:\jenkins\workspace\mybatfile.bat %pv% %p%"
The error I get is that cmd is not recognized as an internal or external command operable program or batch file exit 9009
