  • jquery autocomplete filtering

    - by eidylon
    Hello all, I have a page, which uses jQuery Autocomplete on the second two textboxes (investigator and institution). It is getting the data fine, and displaying it, but for some reason it is not filtering the list of data as i continue to type. Anyone know why? Is there something i need to do to turn this on? According to the jQuery site, the only options to the autocomplete initializer are delay, minLength and source. Thanks in advance! I'm using jQ v1.4.1 and jQui v.1.8rc1. Below is the code which I am calling on $(document).ready(). function hookUpAutoCompletes() { $('table#params input[name=sinvestigator]').autocomplete({ source: "json-investigators.asp", minLength: 2 }) $('table#params input[name=sinstitution]').autocomplete({ source: "json-institutions.asp", minLength: 2 }) }

  • Filtering MySQL query result according to a interval of timestamp

    - by celalo
    Let's say I have a very large MySQL table with a timestamp field. So I want to filter out some of the results not to have too many rows because I am going to print them. Let's say the timestamps are increasing as the number of rows increase and they are like every one minute on average. (Does not necessarily to be exactly once every minute, ex: 2010-06-07 03:55:14, 2010-06-07 03:56:23, 2010-06-07 03:57:01, 2010-06-07 03:57:51, 2010-06-07 03:59:21 ...) As I mentioned earlier I want to filter out some of the records, I do not have specific rule to do that, but I was thinking to filter out the rows according to the timestamp interval. After I achieve filtering I want to have a result set which has a certain amount of minutes between timestamps on average (ex: 2010-06-07 03:20:14, 2010-06-07 03:29:23, 2010-06-07 03:38:01, 2010-06-07 03:49:51, 2010-06-07 03:59:21 ...) Last but not least, the operation should not take incredible amount of time, I need this functionality to be almost fast as a normal select operation. Do you have any suggestions?

  • Filtering model results for Django admin select box

    - by blcArmadillo
    I just started playing with Django today and so far am finding it rather difficult to do simple things. What I'm struggling with right now is filtering a list of status types. The StatusTypes model is: class StatusTypes(models.Model): status = models.CharField(max_length=50) type = models.IntegerField() def __unicode__(self): return self.status class Meta: db_table = u'status_types' In one admin page I need all the results where type = 0 and in another I'll need all the results where type = 1 so I can't just limit it from within the model. How would I go about doing this?

  • Django Haystack exact filtering

    - by blackrobot
    I have a haystack search which has the following SearchIndex: class GrantIndex(indexes.SearchIndex): """ This provides the search index for the Grant application. """ text = indexes.CharField(document=True, use_template=True) year = indexes.IntegerField(model_attr='year__year') date = indexes.DateField(model_attr='date') program = indexes.CharField(model_attr='program__area') grantee = indexes.CharField(model_attr='grantee') amount = indexes.IntegerField(model_attr='amount') site.register(Grant, GrantIndex) If I want to search filtering out any programs that ARE NOT 'Health', I run the following query: from haystack.query import SearchQuerySet sqs = SearchQuerySet() sqs = sqs.filter(program='Health') Unfortunately, this also produces objects from the program 'Health\Other' and 'Health\Cardiovascular'. How do I stop the search from allowing those other programs in? I run Ubuntu 9.10 with Xapian as my search back-end.

  • Filtering A MySQL Result Set Based On The Return Value Of A Function

    - by Joshua
    I'm a SQL noob, and I need a little bit of help understanding the big picture of if it is possible, and if so how to go about filtering a result set based on the return value of a function which is passed one of the fields of the record. Let's say I have a table called "Numbers" with just one field: "Value". How could I correctly specify the following "pseudo-sql"?: SELECT Value FROM numbers WHERE IsPrime(Value)=true Can I accomplish such a thing, and if so, where/how do I put/store "IsPrime"? I'm using MySQL.

  • Objectdatasource and Gridview : Sorting, paging, filtering

    - by Simon
    Hi there, Im using entity framework 1.0 and trying to feed out a Gridview with a objectdatasource that have access to my facade. The problem is, that it seems to be particulary difficult and haven't seen anything that realy do what i want it to do on the internet. For those who know, a gridview feeded with an objectdatasource, it can't sort automaticaly then you must do it manually. It's not that bad. Where it becomes a nightmare, its when we add paging and filter settings to a gridview's datasource. After many hours searching on the internet, i'm asking you, guys, if anyone knows a link that can explain me how to mix Pagging, Sorting and filtering for a gridview and an objectdatasource! Thanks in advance and sorry for my english.

  • .NET CF on Windows CE - problem with filtering system messages

    - by mack369
    Hello, I'm trying to get every windows message that tells that the user has touched the screen. It works everywhere, except the button, when it is disabled. It seems that the application doesn't get any message when clicked on disabled control. I'm using OpenNetCF Application2 class for filtering messages: Application2.AddMessageFilter(Device.PowerManager); Application2.Run(new MainForm()); PowerManager class contains a following method (as required by IMessageFilter interface): public bool PreFilterMessage(ref Microsoft.WindowsCE.Forms.Message m) { log.DebugFormat("windows message {0} - 0x{0:X}", m.Msg); if (m.Msg == 0x0201 || m.Msg == 0x8001 || m.Msg == 0x0005) { return this.ResetPowerManager(); } return false; } in the log file there is no indication of a windows message when clicking on disabled button. I'm wondering how is it possible and how can I get this message.

  • Filtering results and pagination

    - by alj
    I have a template that shows a filter form and below it a list of the result records. I bind the form to the request so that the filter form sets itself to the options the user submitted when the results are returned. I also use pagination. Using the code in the pagination documentation means that when the user clicks for the next page, the form data is lost. What is the best way of dealing with pagination and filtering in this way? Passing the querystring to the paginiation links. Change the pagination links to form buttons and therefore submit the filter form at the same time, but this assumes that the user hasn't messed about with the filter options. As above but with the original data as hidden fields. ALJ

  • List filtering: list comprehension vs. lambda + filter

    - by Agos
    I happened to find myself having a basic filtering need: I have a list and I have to filter it by an attribute of the items. My code looked like this: list = [i for i in list if i.attribute == value] But then i thought, wouldn't it be better to write it like this? filter(lambda x: x.attribute == value, list) It's more readable, and if needed for performance the lambda could be taken out to gain something. Question is: are there any caveats in using the second way? Any performance difference? Am I missing the Pythonic Way™ entirely and should do it in yet another way (such as using itemgetter instead of the lambda)? Thanks in advance

  • Making linq avoid using in memory filtering where possible

    - by linqmonkey
    Consider the these two LINQ2SQL data retrieval methods. The first creates a 'proper' SQL statement that filters the data, but requires passing the data context into the method. The second has a nicer syntax but loads the entire list of that accounts projects, then does in memory filtering. Is there any way to preserve the syntax of the second method but with the performance advantage of the first? public partial class Account { public IQueryable<Project> GetProjectsByYear(LinqDataContext context, int year) { return context.Projects.Where(p => p.AccountID==this.AccountID && p.Year==year).OrderBy(p => p.ProjectNo) } public IQueryable<Project> GetProjectsByYear(int year) { return this.Projects.Where(p => p.Year==year).OrderBy(p => p.ProjectNo).AsQueryable() } }

  • ActionScript Parameter Filtering

    - by TheDarkIn1978
    i'm setting up a custom class that accepts some Number parameters, but i need to limit those parameters and would like to know the best way of doing so. currently, i'm simply calling if statements, and throwing an error if the number is above or below what's accepted. for example, there is a parameter that accepts and angle, but only between 0 and 90. in the case i've typed it as a uint so now i only have to check to see if it's above 90. there's also a parameter Number typed parameter that only accepts values between the range of 0.0 and 1.0. is my method of using if statements and throwing erros the usual way of filtering parameters?

  • Why does calling setScaleX during pinch zoom gesture cause flicker?

    - by numan
    I am trying to create a zoomable container and I am targeting API 14+ In my onScale (i am using the ScaleGestureDetector to detect pinch-zoom) I am doing something like this: public boolean onScale (ScaleGestureDetector detector) { float scaleFactor = detector.getScaleFactor(); setScaleX(getScaleX() * scaleFactor); setScaleY(getScaleY() * scaleFactor); return true; }; It works but the zoom is not smooth. In fact it noticeably flickers. I also tried it with hardware layer thinking that the scaling would happen on the GPU once the texture was uploaded and thus would be super fast. But it made no difference - the zoom is not smooth and flickers weirdly sometimes. What am I doing wrong?

  • ListView items not clickable with HorizontalScrollView inside

    - by Felix
    I have quite a complicated ListView. Each item looks something like this: > LinearLayout (vertical) > LinearLayout (horizontal) > include (horizontal LinearLayout with two TextViews) > include (ditto) > include (ditto) > TextView > HorizontalScrollView (this guy is my problem) > LinearLayout (horizontal) In my activity, when an item is created (getView() is called) I add dynamic TextViews to the LinearLayout inside the HorizontalScrollView (besides filling the other, simpler stuff out). Amazingly, performance is pretty good. My problem is that when I added the HorizontalScrollView, my list items became unclickable. They don't get the orange background when clicked and they don't fire the OnItemClickedListener I have set up (to do a simple Log.d call). How can I make my list items clickable again?

  • Getting real-time market/stock quotes in C#/Java

    - by David Menard
    Hey, I would like to make an program that acts like a big filter for stocks. To do so, I need to have real-time (or delayed) quotes from the market. I started getting stock quotes by requesting pages from yahoo, accordingand parsing the html to the ticker, and parsing the html. I was wondering how to do this requesting and parsing html. Is there some way I can request only the stock quotes and its info? I know some applications do this, and I am very curious how they do it, because requesting web pages and parsing them is very time-consuming. Thanks, Dave

  • Asynchronous Html.ImageGetter for setting multiple images in a TextView

    - by thedude19
    I'm writing an application that takes HTML pages and parses them to display on the screen. Specifically, this application pulls HTML from a message board and lists posts made by users. The problem is that a lot of the content in posts are pictures in <img> tags, so I need to write a Html.ImageGetter to handle the downloading of the images. My textView.setText() method will look like this: myTextView.setText(Html.fromHtml(myText, new ImageGetter() { @Override public Drawable getDrawable(String source) { Drawable d; // Need to async download image here return d; } }, null)); Doing this synchronously is trivial, but is there a suggested way to do this asynchronously so that it doesn't lock up my UI thread? I would also like to eventually build in caching of these images, but I imagine that would be pretty simple once the async downloading was there.

  • Extended SurfaceView's onDraw() method never called

    - by Gab Royer
    Hi, I'm trying to modify the SurfaceView I use for doing a camera preview in order to display an overlaying square. However, the onDraw method of the extended SurfaceView is never called. Here is the source : public class CameraPreviewView extends SurfaceView { protected final Paint rectanglePaint = new Paint(); public CameraPreviewView(Context context, AttributeSet attrs) { super(context, attrs); rectanglePaint.setARGB(255, 200, 0, 0); rectanglePaint.setStyle(Paint.Style.FILL); rectanglePaint.setStrokeWidth(2); } @Override protected void onDraw(Canvas canvas){ canvas.drawRect(new Rect(10,10,200,200), rectanglePaint); Log.w(this.getClass().getName(), "On Draw Called"); } } public class CameraPreview extends Activity implements SurfaceHolder.Callback{ private SurfaceHolder holder; private Camera camera; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); // We remove the status bar, title bar and make the application fullscreen requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // We set the content view to be the layout we made setContentView(R.layout.camera_preview); // We register the activity to handle the callbacks of the SurfaceView CameraPreviewView surfaceView = (CameraPreviewView) findViewById(R.id.camera_surface); holder = surfaceView.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { Camera.Parameters params = camera.getParameters(); params.setPreviewSize(width, height); camera.setParameters(params); try { camera.setPreviewDisplay(holder); } catch (IOException e) { e.printStackTrace(); } camera.startPreview(); } public void surfaceCreated(SurfaceHolder holder) { camera = Camera.open(); } public void surfaceDestroyed(SurfaceHolder holder) { camera.stopPreview(); camera.release(); } }

  • Layout problem: scrollview inside a table, inside a custom dialog

    - by Sean
    I have a layout problem which I can't fix. I've looked through many posts on here, and mine seems to be unique enough to post a question. I've created a custom Dialog which programmatically creates a 3 row table. The top and bottom rows have text, while the middle row contains a ScrollView, which contains a LinearLayout. That LinearLayout then contains some number of views (TextView in this example). Since I'm doing this programmatically, see the XML pseudocode below, and the actual code below that. What I would like to happen, is that when the height of the contained content in the LinearLayout gets too big, the ScrollView does its job, and the header and footer TextView's are always visible. The problem is that when the dialog gets big enough, the ScrollView appears to take over the whole dialog, and my footer TextView disappears off the screen. What can I do to make sure the footer TextView never disappears, but the ScrollView can still function? See the following image links: Footer visible on the left, gone on the right: http://img690.imageshack.us/i/screenshotss.png/ <TableLayout> <TableRow> <TextView> </TableRow> <TableRow> <ScrollView> <LinearLayout> <TextView/> <TextView/> <TextView/> ... </LinearLayout> </ScrollView> </TableRow> <TableRow> <TextView> </TableRow> </TableLayout> Here's the code: public class DialogScrollTest extends Dialog { public DialogScrollTest(Context ctx){ super(ctx); setTitle(""); requestWindowFeature(Window.FEATURE_NO_TITLE); TableLayout table = new TableLayout(ctx); TableRow row; TextView text; row = new TableRow(ctx); { text = new TextView(ctx); text.setText("TestTop"); row.addView(text); } table.addView(row); row = new TableRow(ctx); { ScrollView scroll = new ScrollView(ctx); { LinearLayout linear = new LinearLayout(ctx); linear.setOrientation(LinearLayout.VERTICAL); for(int t=0; t<32; ++t){ text = new TextView(ctx); text.setText("TestScroll"); linear.addView(text); } scroll.addView(linear); } row.addView(scroll); } table.addView(row); row = new TableRow(ctx); { text = new TextView(ctx); text.setText("TestBottom"); row.addView(text); } table.addView(row); this.setContentView(table); } }

  • onPause/onResume activity issues

    - by Josh
    I have a small test application I am working on which has a timer that updates a textview to countdown from 100 to 0. That works fine, but now I am trying to pause the application if the user presses the back button on the phone and then restart the timer from where they left off when they reopen the app. Here is the code I am using: @Override public void onPause() { if(this._timer_time_remaining > 0) { this.timer.cancel(); } super.onPause(); Log.v("Pausing", String.format("Pausing with %d", this._timer_time_remaining)); } @Override public void onResume() { super.onResume(); Log.v("Resuming", String.format("Resuming with %d", this._timer_time_remaining)); if(this._timer_time_remaining > 0) { setContentView(R.layout.in_game); start_timer(this._timer_time_remaining); } } The start_timer() method creates a CountDownTimer which updates the textview in the onTick method and updates the this._timer_time_remaining int variable. CountDownTimer and _timer_time_remaining are both declared at the class level like this: private CountDownTimer timer; private int _timer_time_remaining; From the Log.v() prints I see that the _timer_time_remaining variable has the correct number of seconds stored when onPause is called, but it is set back to 0 when onResume starts. Why does the variable get reset? I thought that the application would continue to run in the background with the same values. Am I missing something? This is all declared in a class that extends Activity. Thanks in advance!

  • Inform Activity from a BroadcastReceiver ONLY if it is in the foreground

    - by Zordid
    Hi there! Maybe it's easy, but I couldn't really figure this out right so far... I got a BroadcastReceiver waiting to get triggered by the AlarmMangager - this works fine. Now: because the event, if it occurs, needs to refresh some elements on screen of the main Activity, I would like to send an Intent from that background BroadcastReceiver to my Activity - but only if it is currently in the foreground, aka active. If it is not running or not visible, I don't care - and the last thing I want to do is start the Activity by my intent! I handle repainting of the views in my onResume method, so I don't care at all. Any hints on how to do that? Thanks! EDIT: my BroadcastReceiver is waiting for alarms that must be notified to the user. So, it must be there and declared in the manifest. The problem is: it will have to decide whether the mentioned Activity is currently up in front or not.

  • Nexus One & Windows XP USB Driver

    - by Stefan
    I've been unable to get my Nexus One working as a development phone on Windows XP. I've got the driver (revision 3 for N1 support), I've got it installed according to the official installation guide, and the phone appears in the Device Manager just as the guide says it should. However, adb still can't find the phone. 'adb devices', for example, returns no active devices. Am I forgetting some basic step? One thing I've noticed is that the driver is labeled in Windows as version 2 released November, 2009 (I need version 3 from January 2010 for N1 support). However, I've never had version 2 installed. I've used the SDK to download version 3 several times - even deleted it and redownloaded it. I've uninstalled/reinstalled the version 3 driver multiple times. It still says version 2. Is this the problem, or this something completely unrelated? Note: The phone is working as a dev phone on Ubuntu, so I know the phone/cable/etc. are good. It's either my fault or the driver's.

  • Linux Mint something wrong with my .bashrc
