Hello guys,
I have an error I cannot solve, on a ASP.NET website.
One of its pages - Countries.aspx, has the following controls:
a CheckBox called "CheckBoxNAME":
< asp:CheckBox ID="CheckBoxNAME" runat="server" Text="Name" />
a TextBox called "TextBoxName":
< asp:TextBox ID="TextBoxNAME" runat="server" Width="100%" Wrap="False"> < /asp:TextBox>
a SQLDataSource called "SqlDataSourceCOUNTRIES", that selects all records from a Table with 3 columns - ID (Number, PK), NAME (Varchar2(1000)), and POPULATION (Number) called COUNTRIES
< asp:SqlDataSource
ID="SqlDataSourceCOUNTRIES"
runat="server"
ConnectionString="< %$ ConnectionStrings:myDB %> "
ProviderName="< %$ ConnectionStrings:myDB.ProviderName %> "
SelectCommand="SELECT COUNTRIES.ID, COUNTRIES.NAME, COUNTRIES.POPULATION FROM COUNTRIES ORDER BY COUNTRIES.NAME, COUNTRIES.ID">
< /asp:SqlDataSource>
a GridView called GridViewCOUNTRIES:
< asp:GridView
ID="GridViewCOUNTRIES"
runat="server"
AllowPaging="True"
AllowSorting="True"
AutoGenerateColumns="False"
DataSourceID="SqlDataSourceCOUNTRIES"
DataKeyNames="ID"
DataMember="DefaultView">
< Columns>
< asp:CommandField ShowSelectButton="True" />
< asp:BoundField DataField="ID" HeaderText="Id" SortExpression="ID" />
< asp:BoundField DataField="NAME" HeaderText="Name" SortExpression="NAME" />
< asp:BoundField DataField="POPULATION" HeaderText="Population" SortExpression="POPULATION" />
< /Columns>
< /asp:GridView>
a Button called ButtonFilter:
< asp:Button ID="ButtonFilter" runat="server" Text="Filter" onclick="ButtonFilter_Click"/>
This is the onclick event:
protected void ButtonFilter_Click(object sender, EventArgs e)
{
Response.Redirect("Countries.aspx?" +
(this.CheckBoxNAME.Checked ? string.Format("NAME={0}", this.TextBoxNAME.Text) : string.Empty));
}
Also, this is the main onload event of the page:
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
if (Request.QueryString.Count != 0)
{
Dictionary parameters = new Dictionary();
string commandTextFormat = string.Empty;
if (Request.QueryString["NAME"] != null)
{
if (commandTextFormat != string.Empty && commandTextFormat.EndsWith("AND") == false)
{
commandTextFormat += "AND";
}
commandTextFormat += " (UPPER(COUNTRIES.NAME) LIKE '%' || :NAME || '%') ";
parameters.Add("NAME", Request.QueryString["NAME"].ToString());
}
this.SqlDataSourceCOUNTRIES.SelectCommand = string.Format("SELECT COUNTRIES.ID, COUNTRIES.NAME, COUNTRIES.POPULATION FROM COUNTRIES WHERE {0} ORDER BY COUNTRIES.NAME, COUNTRIES.ID", commandTextFormat);
foreach (KeyValuePair parameter in parameters)
{
this.SqlDataSourceCOUNTRIES.SelectParameters.Add(parameter.Key, parameter.Value.ToUpper());
}
}
}
}
Basicly, the page displays in the GridViewCOUNTRIES all the records of table COUNTRIES.
The scenario is the following:
- the user checks the CheckBox;
- the user types a value in the TextBox (let's say "ch");
- the user presses the Button;
- the page loads displaying only the records that match the filter criteria (in this case, all the countries that have names containing "Ch");
- the user clicks on the header of the column called "Name" in order to sort the data in the GridView
Then, I get the following error: ORA-01036: illegal variable name/number.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.OracleClient.OracleException: ORA-01036: illegal variable name/number
Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Any help is greatly appreciated, tnks.
PS: I'm using ASP.NET 3.5, under Visual Studio 2008, with an OracleXE database.
I have the following model:
class Service(models.Model):
ratings = models.ManyToManyField(User)
Now if I wanna get all the service with ratings sorted in descending order I did something:
services_list = Service.objects.filter(ratings__gt=0).distinct()
services_list = list(services_list)
services_list.sort(key=lambda service: service.ratings.all().count(), reverse=True)
As you can see its a three step process and I don't feel right about this. Anybody who knows a better way to do this?
We have a requirement to log IP address information of all users who use a certain web application based on JEE 5. What would be an appropriate sql data type for storing IPv4 or IPv6 addressses in the following supported databases (h2, mysql, oracle). There is also a need to filter activity from certain IP addresses. Should I just treat the representation as a string field (say varchar(32) to hold ipv4, ipv6 addresses)
How can you select an element that has current focus?
There is no :focus filter in jQuery, that is why we can use something like this:
$('input:focus').someFunction();
What I would like to achive is:
I go to admin site, apply some filters to the list of objects
I click and object edit, edit, edit, hit 'Save'
Site takes me to the list of objects... unfiltered. I'd like to have the filter from step 1 remembered and applied.
Is there an easy way to do it?

How do i filter duplicates of two arrays before appending entries to a DOM node (#list)?

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?
My sql query gives the columns:
product_id (which is an integer)
pnl (which is float - can be negative)
I get more than 100 rows.
I want to filter out the top 40 rows based on abs(pnl).
But the results should be ordered by pnl column only and not by abs(pnl).
I want to do this for MSSQL 2005.
Is there a way to do this?

What's the cleanest way of filtering a Python string through an external program? In particular, how do you write the following function?
def filter_through(s, ext_cmd):
# Filters string s through ext_cmd, and returns the result.
# Example usage:
# filter a multiline string through tac to reverse the order.
filter_through("one\ntwo\nthree\n", "tac")
# => returns "three\ntwo\none\n"
Note: the example is only that - I realize there are much better ways of reversing lines in python.
In python (it's a Django filter), I'm doing this:
lReturn = re.sub(r'\[usecase:([ \w]+)]', r'EXTEND WITH <a href="/usecase/%s/\1/">\1</a>' % pCurrentProjectName, lReturn)
I'd like to use a function instead of a string (so I can check that the usercase is a valid name), so it would change to this:
def _match_function(matchobj):
lMatch = matchobj.group(1)
return "EXTEND WITH <a href='/usecase/%s/%s/'>%s</a>" % (pCurrentProjectName, lMatch, lMatch)
lReturn = re.sub(r'\[usecase:([ \w]+)]', _match_function, lReturn)
How do I get pCurrentProjectName into the _match_function() function?
I have a gridview (Edit and Delete enabled) that shows a table. A Text Box and A Button. When I type something in the textbox and click the button, the button runs the datasource.filterexpression and filters out the rows.
The question whenever I click on the edit button after the filter has been applied The grid auto resets back to the original table? How can I solve this?
Hi All,
We have a system which performs a 'coarse search' by invoking an interface on another system which returns a set of Java objects. Once we have received the search results I need to be able to further filter the resulting Java objects based on certain criteria describing the state of the attributes (e.g. from the initial objects return all objects where x.y z && a.b == c).
The criteria used to filter the set of objects each time is partially user configurable, by this I mean that users will be able to select the values and ranges to match on but the attributes they can pick from will be a fixed set.
The data sets are likely to contain <= 10,000 objects for each search. The search will be executed manually by the application user base probably no more than 2000 times a day (approx). It's probably worth mentioning that all the objects in the result set are known domain object classes which have Hibernate and JPA annotations describing their structure and relationship.
Off the top of my head I can think of 3 ways of doing this:
For each search persist the initial result set objects in our database, then use Hibernate to re-query them using the finer grained criteria.
Use an in-memory Database (such as hsqldb?) to query and refine the initial result set.
Write some custom code which iterates the initial result set and pulls out the desired records.
Option 1 seems to involve a lot of toing and froing across a network to a physical Database (Oracle 10g) which might result in a lot of network and disk activity. It would also require the results from each search to be isolated from other result sets to ensure that different searches don't interfere with each other.
Option 2 seems like a good idea in principle as it would allow me to do the finer query in memory and would not require the persistence of result data which would only be discarded after the search was complete. Gut feeling is that this could be pretty performant too but might result in larger memory overheads (which is fine as we can be pretty flexible on the amount of memory our JVM gets).
Option 3 could be very performant but is something I would like to avoid as any code we write would require such careful testing that the time taken to acheive something flexible and robust enough would probably be prohibitive.
I don't have time to prototype all 3 ideas so I am looking for comments people may have on the 3 options above, plus any further ideas I have not considered, to help me decide which idea might be most suitable. I'm currently leaning toward option 2 (in memory database) so would be keen to hear from people with experience of querying POJOs in memory too.
Hopefully I have described the situation in enough detail but don't hesitate to ask if any further information is required to better understand the scenario.
Cheers,
Edd
Is it possible to capture all the sound from a computer and have it pass through a equalizer before reaching the speakers?
How can you program a band pass filter on it?
EDIT: I'm trying to get this on Windows (with Python? heh) but if there is a generic, cross-platform approach that would be great.

});
});
i wrote the above jQuery script to append some site name to all the links in the page but it's not working as expected.
I can not figure out why my code does not filter out lists from a predefined list.
I am trying to remove specific list using the following code.
data = [[1,1,1],[1,1,2],[1,2,1],[1,2,2],[2,1,1],[2,1,2],[2,2,1],[2,2,2]]
data = [x for x in data if x[0] != 1 and x[1] != 1]
print data
My result:
data = [[2, 2, 1], [2, 2, 2]]
Expected result:
data = [[1,2,1],[1,2,2],[2,1,1],[2,1,2],[2,2,1],[2,2,2]]
To get image thumbnails on BlackBerry I use EncodedImage.scaleImage32(). It works Ok, but when I open native image viewer (from the Camera app) I see the difference in quality - native viewer thumbnails look nice (smooth, anti-aliased), while mine are a bit ugly. Looks like native viewer resizes images using some filter (bicubic or smth like that). How can I do the same? Is there some API for "smooth" resizing?
XML spec defines a subset of Unicode characters which are allowed in XML documents:

I run a site where users can upload content that is displayed in a gallery where other users can sort and filter that content. While implementing RSS feeds, I was wondering how common it was for an RSS feed to display items in an order that's different from chronological. For example, displaying content by Most Views first. This could be useful for someone wanting to keep tabs on trending content. How do RSS readers handle this, since most RSS feeds are ordered chronologically?
