after selecting the date from the date picker, i am getting the date in the format in view like yy/mm/dd .
i want to the date format in my view like mm/dd/yy.
how can i do this.
Let's say I have a user registration and I'm using the Auth component (/user/register is allowed of course).
The problem is if I need to set a minLength validation rule in the model, it doesn't work since the Auth component hashes the password therefore it's always more than my minlength password and it passes even if it's blank.
How do I fix this issue? Thanks in advance!
As the title says: What techniques are available for filtering objects when using zodb?
The equivalent in SQL terms would be something like filtering results by a date range. Or only returning rows with a particular value set in a column.
If I had a series of blog posts and only wanted ones done in the past month, what would I have to do? Is there any way to optimize these kinds of "queries"?
My gut tells me iterating over all the objects in a relationship simply to perform a test is less than optimal.
My html form is spreading over several pages (steps), and I want to let the use to take step back in case they would like to change something they filled in. So, I don't want to make users re-type all the information they already have typed once. Thus, how would I make it so that all the information would go back, to speak so? (I use PHP on server-side.)
Consider the 0/1 knapsack problem.
The standard Dynamic Programming algorithm applies only when the capacity as well as the weights to fill the knapsack with are integers/ rational numbers. What do you do when the capacity/weights are irrational?
The issue is that we can't memoize like we do for integer weights because we may need potentially infinite decimal places for irrational weights - leading to an infinitely large number of columns for the Dynamic Programming Table .
Is there any standard method for solving this? Any comments on the complexity of this problem? Any heuristics?
What about associated recurrences like (for example):
f(x)=1, for x< sqrt(2)
f(x)=f(x-sqrt(2))+sqrt(3)
I am developing a search dialog in my eclipse-rcp application.
In the search dialog I have a combobox as follows:
comboImp = new CCombo(grpColSpet, SWT.BORDER | SWT.READ_ONLY);
comboImp.setBounds(556, 46, 184, 27);
comboImpViewer = new ComboViewer(comboImp);
comboImpViewer.setContentProvider(new ArrayContentProvider());
comboImpViewer.setInput(ImpContentProvider.getInstance().getImps());
comboImpViewer.setLabelProvider(new LabelProvider() {
@Override
public String getText(Object element) {
return ((Imp)element).getImpName();
}
});
Imp is a database entity, ManyToOne to the main entity which is searched, and ImpContentProvider is the model class which speaks to embedded sqlite database via jpa/hibernate.
This combobox is supposed to contain all instances of Imp, but to also let empty selection; it's value is bound to a service bean as follows:
IObservableValue comboImpSelectionObserveWidget =
ViewersObservables.observeSingleSelection(comboImpViewer);
IObservableValue filterByImpObserveValue =
BeansObservables.observeValue(searchPrep, "imp");
bindingContext.bindValue(comboImpSelectionObserveWidget, filterByImpObserveValue
, null, null);
As soon as the user clicks on the combo, a selection (first element) is made: I can see the call to a selectionlistener i added on the viewer. My question is:
after a selection has been made, how do I let the user change his mind and have an empty selection in the combobox? should I add a "fake" empty instance of Imp to the List returned by the ImpContentProvider? or should I implement an alternative to ArrayContentProvider?
and one additional related question is:
why calling deselectAll() and clearSelection() on the combo does NOT set a null value to the bound bean?
I'm having trouble figuring out what the best solution is given the following situation. I'm using Prism 4.1, MEF, and .Net 4.0.
I have an object Project that could have a large number (~1000) of Line objects. I'm deciding whether it is better to expose an ObservableCollection<LineViewModel> from my ProjectViewModel and manually create the Line viewmodels there OR set the ListBox as it's own region and activate views that way.
I'd still want my LineViewModel to have Prism's shared services (IEventAggregator, etc.) injected, but I don't know how to do that when I manually create the LineViewModel. Any suggestions or thoughts?
I can't for the life of me figure out why this function is causing multiple entries into my database table...
When I run the function I end up with two records stacked on top of each one second apart
here is the function:
function generate_signup_token(){
$connection = new DB_Connect(); // <--- my database connection class
$ip = mysql_real_escape_string($_SERVER['REMOTE_ADDR']);
$sign_up_token = uniqid(mt_rand(), true);
$_SESSION['signup_token'] = $sign_up_token;
$sign_up_token = mysql_real_escape_string($sign_up_token);
$query = "INSERT INTO `token_manager` (`ip_address`, `signup_token`) VALUES ('$ip', '$sign_up_token')";
mysql_query($query);
}
generate_signup_token();
We have to maintain and even develop C-code of our legacy system. Is there good collection library that would support Java/C# (new versions) style collections. Hashtable, HashSet, etc. Of course without objects, but with structs. The HashTable key limitations to "strings" and ints is not a problem. It wouldn't be bad if it's free even for commercial use. I'm back to C from C# and I must say i'm depressed using our own libraries and the language in general. We're using VS2005 and MS C-compiler if that has nothing to do with anything.
Thanks & BR -Matti
My web application deals with strings that need to be converted to numbers alot - users often put commas, currency symbols etc. in these fields so what I want to do is create a string extension method that cleans the field up and converts it to a decimal.
For example:
decimal myNumber = "$1,250.85".ToDecimal();
Can anyone help with this? Thanks!
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
I have a test django app.
In one page the test show the same question to all users.
I'd like that when a user answers correctly, send a signal to other active user's browser to refresh to the next question.
I have been learning about signals in django I learning work with them but I don't now how send the "refresh signal" to client browser.
I think that it can do with a javascript code that check if a certain value (actual question) change and if change reload the page but I don't know this language and the information that I find was confused.
Can anybody help me?
Many Thanks.
Hi all,
I have been implementing a new project which I have decided to use the repository pattern and Entity Framework.
I have sucessfuly implemented basic CRUD methods and I have no moved onto my DeepLoads.
From all the examples and documentation I can find to do this I need to call something like this:
public Foo DeepLoadFoo()
{
return (from foobah in Context.Items.Include("bah").Include("foo").Include("foofoo") select foo).Single();
}
This doesnt work for me, maybe I am trying to be too lazy but what I would like to achieve would be something along the lines of this:
public Foo DeepLoadFoo(Foo entity, Type[] childTypes)
{
return (from foobah in Context.Items.Include(childTypes).Single();
}
Is anything like this possible, or am I stuck with include.include.include.include?
Thanks
If an attacker has several distinct items (for example: e-mail addresses) and knows the encrypted value of each item, can the attacker more easily determine the secret passphrase used to encrypt those items? Meaning, can they determine the passphrase without resorting to brute force?
This question may sound strange, so let me provide a use-case:
User signs up to a site with their e-mail address
Server sends that e-mail address a confirmation URL (for example: https://my.app.com/confirmEmailAddress/bill%40yahoo.com)
Attacker can guess the confirmation URL and therefore can sign up with someone else's e-mail address, and 'confirm' it without ever having to sign in to that person's e-mail account and see the confirmation URL. This is a problem.
Instead of sending the e-mail address plain text in the URL, we'll send it encrypted by a secret passphrase.
(I know the attacker could still intercept the e-mail sent by the server, since e-mail are plain text, but bear with me here.)
If an attacker then signs up with multiple free e-mail accounts and sees multiple URLs, each with the corresponding encrypted e-mail address, could the attacker more easily determine the passphrase used for encryption?
Alternative Solution
I could instead send a random number or one-way hash of their e-mail address (plus random salt). This eliminates storing the secret passphrase, but it means I need to store that random number/hash in the database. The original approach above does not require this extra table.
I'm leaning towards the the one-way hash + extra table solution, but I still would like to know the answer: does having multiple unencrypted e-mail addresses and their encrypted counterparts make it easier to determine the passphrase used?
Im using DataServices and OData protocol, i need to generate Get, Post, Delete, and Update from a c++ aplication. how i can do this? the easiest way ??
I want to know why we always use Sorting algorithm like (Insertion Sort or Merge Sort,...) just for lists and arrays? And why we do not use these algorithms for stack or queue?
I'm trying to insert records in mysql database using java,
What do I place in this code so that I could insert records:
String id;
String name;
String school;
String gender;
String lang;
Scanner inputs = new Scanner(System.in);
System.out.println("Input id:");
id=inputs.next();
System.out.println("Input name:");
name=inputs.next();
System.out.println("Input school:");
school= inputs.next();
System.out.println("Input gender:");
gender= inputs.next();
System.out.println("Input lang:");
lang=inputs.next();
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/employee_record", "root", "MyPassword");
PreparedStatement statement = con.prepareStatement("insert into employee values('id', 'name', 'school', 'gender', 'lang');");
statement.executeUpdate();
Hello,
I have some stored procedure
DECLARE cursor FOR SELECT [FooData] From [FooTable];
OPEN cursor ;
FETCH NEXT FROM cursor INTO @CurrFooData;
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @CurrFooData AS FooData;
INSERT INTO Bar (BarData) VALUES(@CurrFooData);
FETCH NEXT FROM cursor INTO @CurrFooData;
END;
CLOSE OldestFeeds
DEALLOCATE OldestFeeds
But in result I have a lot of tables, not one. How can I return one table with 'FooData' column and all '@CurrFooData' rows?
Using a three-tier architecture, I have a list of objects
List<object> careerList = new List<object>();
ModuleDTO module = new ModuleDTO();
careerList = module.getDegreeCodeByQualification(qualificationCode);
which I then add to a gridview like so:
gridViewMaster.DataSource = careerList;
gridViewMaster.DataBind();
What I'd like to do is then enable paging on the gridview. My gridview so far is:
<asp:GridView ID="gridViewMaster" runat="server"
AutoGenerateColumns="False" GridLines="None"
BorderWidth="1px" CellPadding="2" DataKeyNames="Grouping"
ForeColor="Black"
onrowdatabound="gridViewMaster_RowDataBound" CssClass="mGrid" PagerStyle-CssClass="pgr"
AlternatingRowStyle-CssClass="alt" OnPageIndexChanging="gridView_PageIndexChanging"
AllowPaging="True" >
Is it possible to do enable paging on a list's without having to change that list to a Datatable or Dataview? If there is a way, this would help a lot.
So far my events are as follows:
protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gridViewMaster.PageIndex = e.NewPageIndex;
List<object> careerList = new List<object>();
ModuleDTO module = new ModuleDTO();
careerList = module.getDegreeCodeByQualification(qualificationCode);
ModalProgress.Show();
System.Threading.Thread.Sleep(1000);
JobPanel.Visible = true;
gridViewMaster.DataSource = careerList.Distinct();
gridViewMaster.DataBind();
}
Someone PLEASE HELP ME!!! Thank you
I have a hard question. I'd like the joomla login does not use its own database for users/password but I want to use my database users with my table fields, my passwords etc..
I don't know from where start, I thought I could edit database request for login to my db or create a little script to automatically add the users on joomla database.
I tried to see components/com_users/views/login/tmpl/default_login.php but it seems that there is nothing.
Can someone help me figure out what to change?
Maybe the simple thing is import my database users into database user joomla, is there any plugin or something else that you know?
p.s. I use Clarion theme build on Gantry framework, Joomla! 2.5.6 Stable, PHP 5.2.17
Every Customer has a physical address and an optional mailing address. What is your preferred way to model this?
Option 1. Customer has foreign key to Address
Customer (id, phys_address_id, mail_address_id)
Address (id, street, city, etc.)
Option 2. Customer has one-to-many relationship to Address, which contains a field
to describe the address type
Customer (id)
Address (id, customer_id, address_type, street, city, etc.)
Option 3. Address information is de-normalized and stored in Customer
Customer (id, phys_street, phys_city, etc. mail_street, mail_city, etc.)
One of my overriding goals is to simplify the object-relational mappings, so I'm leaning towards the first approach. What are your thoughts?
I have a model that looks like this:
class Client(models.Model):
name = models.CharField(max_length=100, primary_key=True)
user = models.ForeignKey(User)
class Contract(models.Model):
title = models.CharField(max_length=100, primary_key=True)
start_date = models.DateField()
end_date = models.DateField()
description = models.TextField()
client = models.ForeignKey(Client)
user = models.ForeignKey(User)
How can i configure a django form so that only clients associated with that user show in the field in the form?
My initial thought was this in my forms.py:
client = forms.ModelChoiceField(queryset=Client.objects.filter(user__username = User.username))
But it didn't work. So how else would I go about it?
I ned to write a code sniplet that enables to disable connection to some parts of a site. Admin and the mainpage will be displayable, but user section (which uses ajax) will be displayed, but can not be used (vith a transparent div set over the page). Also there is a few pages which will be disabled.
my logic is that, i write a middleware,
def process_request(self, request):
if ayar.tonline_kapali:
url_parcalari = request.path.split('/')
if url_parcalari[0] not in settings.BAGIMSIZ_URLLER:
if not request.is_ajax():
return render_to_response('bakim_modu.html')
else:
return None
that code let me to display a "site closed" message for the urls not in BAGIMSIZ_URLLER (which contains urls that will be accessible)
But i do not figure out how can i solve the problem about ajax pages... i need to set a header or something to the response and need to check it in the template.
