• Effective Method to Manage and Search Through 100,000+ Objects Instantly? (C#)

  - by Kirk

  I'm writing a media player for enthusiasts with large collections (over 100,000 tracks) and one of my main goals is speed in search. I would like to allow the user to perform a Google-esque search of their entire music collection based on these factors: Song Path and File Name Items in ID3 Tag (Title, Artist, Album, etc.) Lyrics What is the best way for me to store this data and search through it? Currently I am storing each track in an object and iterating over an array of these objects checking each of their variables for string matches based on given search text. I've run into problems though where my search is not effective because it is always a phrase search and I'm not sure how to make it more fuzzy. Would an internal DB like SQLlite be faster than this? Any ideas on how I should structure this system? I also need playlist persistence, so that when they close the app and open the app their same playlist loads immediately. How should I store the playlist information so it can load quickly when the application starts? Currently I am JSON encoding the entire playlist, storing it in a text file, and reading it into the ListView at runtime, but it is getting sluggish over 20,000 tracks. Thanks!

• How to Implement Custom List View for the list Items in Android Application

  - by avadhani

  I had a problem with the list view having both parent list and the child list of the list activity(implemented through database query). I wish to show them differing their properties by changing the text style (parent list items are in bold, child list items are in normal style). The following is the code from which all the child and parent list items having the same style(bold): String sql = "SELECT Parentid,Childid,Name from (select com.Parentid, com.Childid, com.Name from table1 mem inner join table2 cd on mem.column1=cd.column1 inner join table3 com on com.childid = mem.childid where Parentid is NULL UNION SELECT com.Parentid, com.Childid,com.Name from table1 mem inner join table3 com on com.childid = mem.childid inner join table2 cd on mem.column1=cd.column1 where Parentid is NOT NULL) a group by Parentid, Childid;"; Cursor cdata = myDbHelper.getView(sql); and the List Adapter is: private static final String fields[] = {"Name"}; int[] names = new int[] {R.id.name}; SimpleCursorAdapter adapter2 = new SimpleCursorAdapter(this,R.layout.clientlist1, cdata, fields,names ); and the clientlist.xml is: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/MainLayout" android:padding="5px"> <TextView android:id="@+id/name" android:layout_alignParentRight="true" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="12sp" android:textColor="#104082" android:textStyle="bold" android:layout_weight="1" /> From this i am getting the list having the complete list having both parent and child list items in a single list view. I wish to differ in their text style(bold, normal) for parent and child items respectively. Please help me with the code/links. Thanks a lot in advance.

• How does the NY Times iPhone app do this?

  - by ArgMan

  Alright, I have an RSS feed that gets arranged in a UITableView and then the user selects a story and it loads in a UIWebView. However, I'd like to stop using the UIWebView and just use a UITextView or UILabel. This png is what I am trying to do (just display the various text aspects of a news story): http://img411.imageshack.us/img411/2449/screenshot20100315at120.png Let me start off by saying that I have tried to use the usualNSString *myText = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.textContent"]; and assign it to a UILabel, but it doesn't work the way that I am implementing it (in webViewDidFinishLoad--is that not correct?) and I get a blank textView and normal webView. If I overlay a UITextView on top of a UIWebView on its own (that is, a webView that just loads one page), the code posted above works fine to display the text I require, but the problem arises when the RSS feed is added into the mix. Ideas and/or help, guys? I've been stuck wondering why this doesn't work as it should for a few days now. If you have a better, more efficient way of doing it then placing the code in webViewDidFinishLoad, please let me know! Does it go in my didSelectRowAtIndexPath? I'm lost here, guys. Thank you very much in advance!

• Python program to search for specific strings in hash values (coding help)

  - by Diego

  Trying to write a code that searches hash values for specific string's (input by user) and returns the hash if searchquery is present in that line. Doing this to kind of just learn python a bit more, but it could be a real world application used by an HR department to search a .csv resume database for specific words in each resume. I'd like this program to look through a .csv file that has three entries per line (id#;applicant name;resume text) I set it up so that it creates a hash, then created a string for the resume text hash entry, and am trying to use the .find() function to return the entire hash for each instance. What i'd like is if the word "gpa" is used as a search query and it is found in s['resumetext'] for three applicants(rows in .csv file), it prints the id, name, and resume for every row that has it.(All three applicants) As it is right now, my program prints the first row in the .csv file(print resume['id'], resume['name'], resume['resumetext']) no matter what the searchquery is, whether it's in the resumetext or not. lastly, are there better ways to doing this, by searching word documents, pdf's and .txt files in a folder for specific words using python (i've just started reading about the re module and am wondering if this may be the route, rather than putting everything in a .csv file.) def find_details(id2find): resumes_f=open("resume_data.csv") for each_line in resumes_f: s={} (s['id'], s['name'], s['resumetext']) = each_line.split(";") resumetext = str(s['resumetext']) if resumetext.find(id2find): return(s) else: print "No data matches your search query. Please try again" searchquery = raw_input("please enter your search term") resume = find_details(searchquery) if resume: print resume['id'], resume['name'], resume['resumetext']

• Parsing data from txt file in J2ME

  - by CSFYPMAIL

  Basically I'm creating an indoor navigation system in J2ME. I've put the location details in a .txt file i.e. Locations names and their coordinates. Edges with respective start node and end node as well as the weight (length of the node). I put both details in the same file so users dont have to download multiple files to get their map working (it could become time consuming and seem complex). So what i did is to seperate the deferent details by typing out location Names and coordinates first, After that I seperated that section from the next section which is the edges by drawing a line with multiple underscores. Now the problem I'm having is parsing the different details into seperate arrays by setting up a command (while manually tokenizing the input stream) to check wether the the next token is an underscore. If it is, (in pseudocode terms), move to the next line in the stream, create a new array and fill it up with the next set of details. I found a some explanation/code HERE that does something similar but still parses into one array, although it manually tokenizes the input. Any ideas on what to do? Thanks Text File Explanation The text has the following format... <--1stSection--  /**   * Section one has the following format   * xCoordinate;yCoordinate;LocationName   */ 12;13;New York City 40;12;Washington D.C. ...e.t.c _________________________ <--(underscore divider) <--2ndSection--  /**   * Its actually an adjacency list but indirectly provides "edge" details.   * Its in this form   * StartNode/MainReferencePoint;Endnode1;distance2endNode1;Endnode2;distance2endNode2;...e.t.c   */ philadelphia;Washington D.C.;7;New York City;2 New York City;Florida;24;Illinois;71 ...e.t.c

• jquery carousel auto scroll with text and image

  - by Evan

  I'm using the jquery carousel and I have the image auto rotating here ( http://jsbin.com/unoce/2), so the issue I'm having is the content on the left is not AUTO rotating "with" the image and the arrow selection is not either. It only works when I click the content on the left and then the image on the right along with the arrow move appropriately together. Can someone provide support so I may get the text and the arrow to "auto" rotate with the image? This code below would only rotate the image and nothing else... jQuery(document).ready(function() { jQuery("#features").jcarousel({ scroll: 1, auto:2, wrap: 'both', initCallback: mycarousel_initCallback, buttonNextHTML: null, buttonPrevHTML: null }); }); Here's a demo and you can edit this demo too: http://jsbin.com/unoce/2 Thank you, Evan

• Image map popup on rollover, with popup text drawn from database

  - by lbholland

  I have a custom map of the USA with about 20 polygonal hot spots. I would like a box to pop up next to each hot spot on hover, with text and links drawn from my DB specific to the location. I would have thought this is a common situation, but I can't find a solution that works. I tried using an asp:imagemap and an ajax popup extender but you can't assign IDs to hotspots and it doesn't support mouseover events. I tried css with an html image map but I can't figure out how to use css solutions with polygonal hot spots, and I also don't know how to link it to get the data from the db without asp targets (I'm not very familiar with jquery, which would work, I am guessing). Anyone know of any simple-ish solutions out there?

• IPhone Plain TableView Section Header Image and Getting Text on Two Lines

  - by jp

  Hello, this is my first question, so if I didn't do the tags correctly, I'm sorry. I tried... Well here is my question: I am hoping someone can tell me how to do a 2-line section header for a plain tableview. The problems I am having are: 1) I cannot find an image that will mimic that of the default 1-line section header. Can someone share one with me, or tell me how I can find one? 2) I cannot seem to get the section header text on two lines, since I am pulling it from the fetched results controller, a "field" (sorry if wrong terminology) that I custom defined on the class for my table. So this "field" has multiple field values in it, and I have no way to take them apart... Any help would be appreciated.

• Replace text in Word Document via ASP.NET

  - by jreedinc

  How can I replace a string/word in a Word Document via ASP.NET? I just need to replace a couple words in the document, so I would like to stay AWAY from 3rd party plugins & interop. I would like to do this by opening the file and replacing the text. The following attempts were made: I created a StreamReader and Writer to read the file but I think that I am reading and writing in the wrong format. I think that Word Documents are stored in binary?? If word documents are binary, how would I read and write the file in binary? Dim template As String = Request.MapPath("documentName.doc") If File.Exists(template) Then Dim sr As New StreamReader(template) Dim content As String = sr.ReadToEnd() sr.Close() Dim sw As New StreamWriter(template) content = content.Replace("@ T O D A Y S D A T E", Date.Now.ToString("MM/dd/yyyy")) sw.Write(content) sw.Close() Else

• FlowDocument contents as text

  - by tyndall

  What is the best way to get back the XAML/XML value of a FlowDocument? I noticed there isn't a .Value, .Text, .Caption, .ToXml(), etc... UDPATE: I'd like to be able to get access to it initially to serialize to disk or database. Treat it as its own document format. Later translating it to other formats would be nice. Also been wondering: Any equivalent to a hyperlink (opens in new browser window) in a FlowDocument? Any workaround?

• How to implement full text search in Django?

  - by Jannis

  I would like to implement a search function in a django blogging application. The status quo is that I have a list of strings supplied by the user and the queryset is narrowed down by each string to include only those objects that match the string. See: if request.method == "POST": form = SearchForm(request.POST) if form.is_valid(): posts = Post.objects.all() for string in form.cleaned_data['query'].split(): posts = posts.filter( Q(title__icontains=string) | Q(text__icontains=string) | Q(tags__name__exact=string) ) return archive_index(request, queryset=posts, date_field='date') Now, what if I didn't want do concatenate each word that is searched for by a logical AND but with a logical OR? How would I do that? Is there a way to do that with Django's own Queryset methods or does one have to fall back to raw SQL queries? In general, is it a proper solution to do full text search like this or would you recommend using a search engine like Solr, Whoosh or Xapian. What are there benefits? Thanks for taking the time

• jQuery jPicker > Assign color of jPicker from a text link (not from jPicker)

  - by Scott B

  I've got a list of frequently used hex colors that I'd like to list under my jPicker bound input text field and I'd like to figure out how to change the value of the jPicker active color without opening the jPicker color selector palette. I've managed to create a function that updates the input field thats bound to the jPicker, but the colors of the background and picker.gif do not update. I'd like to force the background colors to update as if the color was selected from jPicker itself. Here's my code for the activation link... <span onclick=doColor(1,'cc9900')>cc9900</span> And here's the js handler function doColor(el, color) { if(el){$('#theme_header_color').attr('value', color);} else{$('#theme_sidebar_color').attr('value', color);} }

• javascript onkeypressed not giving current text box content

For example, if I just type "A" into the form, console.log() prints "". And if I type "AA", console.log prints "A". Is there a way to get the current content of the input?

• Value of text box disapears - binding viewmodel to a tab (content control)

  - by Eli Perpinyal

  Based on the MVVM example by Josh Smith, I have implemented the multi tab option which binds to a different tab to a different view model using a simple datatemplate that binds a viewmodel to a view. <DataTemplate DataType="{x:Type fixtureVM:SearchViewModel}"> <SearchVw:SearchView/> </DataTemplate> The issue that I'm having, is when I switch tabs and then switch back again, the value in the textbox disappears. When I bind the Text in the textbox to a value in the ViewModel it does not disappear. This is fine, and I can overcome this but I am having another issue for example with the position of the scroll bar in a grid disappearing once the tab has lost focus. Why is the value disappearing? I'm assuming it is a WPF sub system task that cleans up resources!? how can I avoid this? I also feel it might be slowing down my app.
