I am using EF 3.5 with MVC.
I want to made a search page, has some fields for criteria like date, int etc.
What is the way in linq to entities to filter the result dynamically.
If there are one parameter we can use
.where(a=a.id==1)
but many combination with optional param how can i load results and then pass to model.
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.

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?
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?
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

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.
XML spec defines a subset of Unicode characters which are allowed in XML documents:

How do I filter out these characters from a String in Java?
simple test case:
Assert.equals("", filterIllegalXML(""+Character.valueOf((char) 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?
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?
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?
Is it possible to capture all the sound from a computer and have it pass through a equalizer before reaching the speakers?

I am interested in activating another application's activity. I know from reading the Android SDK that it's probably better to do this with an implicit intent. However, this activity doesn't reside in an application I own, so I don't know the action and category and data flags on the intent-filter.
How can I examine an Android applications metadata like the activity classes and the intent-filters for those activities (if declared in the manifest)?
Thanks!
Hi all,
I currently have a JAX-WS Web Service that receives some credentials in the HTTP header. These are used for BASIC authentication.
There is a filter that performs authentication by reading the HTTP headers and checking against the database.
Still, I need the username from within the Web Service in order to perform other service logic related stuff. Is there a way of accessing the HTTP headers from within the Web Service?
Thanks.
I have a custom template tag:
def uploads_for_user(user):
uploads = Uploads.objects.filter(uploaded_by=user, problem_upload=False)
num_uploads = uploads.count()
return num_uploads
and I'd like to do something like this, so I can pluralize properly:
{% with uploads_for_user leader as upload_count %}
{{ upload_count }} upload{{ upload_count|pluralize }}
{% endwith %}
However, uploads_for_user leader doesn't work in this context, because the 'with' tag expects a single value - Django returns:
TemplateSyntaxError at /upload/
u'with' expected format is 'value as name'
Any idea how I can get round this?
Hi!
I have a collection of elements of type B and C, which all extends A. I need to filter the collection to get elements of only B type.
Is there any way to do it except:
for (A a : initCollection) {
if (a instance of B) {
newCollection.add(a)?
}
}
Thanks
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]]
I'm using jQuery :contains selector to filter through some link tags. The following code works great.
$('a:contains('string').each(function(i){
//do some stuff
});
I'd like only run this function if the anchor tags are inside a specific class, I've tried the following but it does not appear to work:
$('my_class a:contains('string').each(function(i){
//do some stuff
});
I've looked around for a while, but there doesn't seem to be a simple way to do this. jQuery doesn't help the in least, it seems to entirely lack any support for selection or DOM ranges. Something which I hoped would be as simple as $.selection.filter('img') seems to only be doable with dozens of lines of code dealing with manually enumerating elements in ranges and browser implementation inconsistencies (though ierange helps here). Any other shortcuts?
I have poured over every example that I can find and I have gone through the official documentation from google. All I am trying to do is create a toast notification from a button click on a widget.
I can get the widget (and button) to appear but I can't get my intent to fire. I have seen several examples that show doing this different ways but I just can't get it to work. I haven't felt this helpless with coding in a long time and I'm starting to feel dumb.
This is what I have so far:
public class simpleclick extends AppWidgetProvider {
/** Called when the activity is first created. */
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
Toast.makeText(context, "doing on update", Toast.LENGTH_SHORT).show();
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent(context, simpleclick.class);
intent.setAction("ham");
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.main);
views.setOnClickPendingIntent(R.id.Timm, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
//@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(context, "action is: " + intent.getAction(), Toast.LENGTH_SHORT).show();
super.onReceive(context, intent);
}
}
My manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.tblabs.simpleclick"
android:versionCode="1"

<meta-data android:name="android.appwidget.provider"

</telerik:RadMenuItem>
how can i dynamically create the textbox itemTemplate in code behind?
I found a quite large list of available libraries on Node.JS wiki but I'm not sure which of those are more mature and provide better performance. Basically I want to do the following:
load some images to a server from external sources
put them onto one big canvas
crop and mask them a bit
apply a filter or two
Resize the final image and give a link to it
Big plus if the node package works on both Linux and Windows.
I have added a 'cancelled' field to my model, is there a way to modify the model default query to something like cancelled=False ? without having to modify all my filter/exclude queries ?
I recently posted about the Play store not letting me publish my app without a minSdkVersion, but whenever I set it to anything above "1" my app just doesn't work (minSdkVersion breaking program).
So this guy suggested to just set my minSdkVersion to 1, which worked. But now when I submitted my app even though the developer site says:
API level: 1-16+
Supported screens: normal-xlarge
OpenGL textures: all
But the app only shows it supports Android under 4.x, I developed it on my 4.0.4 device. I tried searching around and I found that some people have problems with services messing up the phones it supports, so I deleted all of my services, because I don't really need any for this version of the app to submit. And it still didn't work. So I don't know what else to do, here is my AndroidManifest.xml if it helps... I've been trying to figure out why my application isn't working for a week now, still nothing. I have tried setting a targetSdkVersion to something like 14, my application still breaks. I cleaned out my code, taking everything out of the already short, 200 lines, application, and it still isn't working. Is there something I can't use in an android application 4.0 that I am using in my application? or is it just my AndroidManifest? Thank you so much!
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

I should note,I am using the Theme.Holo.Light, but even if I change it to DeviceDefault it doesn't work.
Edit:
I googled the app on my friends Samsung Galaxy S3 (it didn't show up in the Play Store on his phone), when I installed by googling the app and hitting the "install" button on google and it opened in the Google Play store and was able to install. When I did the same on my phone, Galaxy Note, it opened in the Google Play Store, but then said "Not compatible." Why? They are both on the same version of OS. Why is mine not compatible, nor the One X compatible, but the Samsung Galaxy S3 worked...?
Edit: I get these errors/problems when compiling with a targetSdkVersion, http://pastebin.com/mxgWNLdM
