  • How to set up a database and API web page to accept POST updates from iPhone?

    - by lionfly
    Hi there, I am developing an iPhone app, which now can update Twitter account with GPS coordinates in real-time, by the Twitter API link: http://username:[email protected]/statuses/update.xml , and I am looking at how to make my own database to accept updates from iPhone, via a similar API page. It seems a .php page can serve as the API, and MySQL can serve as the database. What are the good ways of doing it? Any template code and tutorial please?

  • QT List of Callbacks

    - by Talguy
    I am trying to make a real-time data collection application that has timed task. Each task can have a different or the same update period. I would like to store the task with the common update period in a list where I can iterate through it and call the function that I registered in the list. How would I go about adding callbacks to a data structure like a list or vector? Can I store slots in them?

  • Maintaining file permissions across SVN updates?

    - by Mark Mayo
    I have a series of python scripts with execute permissions in Linux. They are stored in SVN. If I then run svn up to update them, the overwritten files are back to 644 - ie no execute permissions for anyone. Yes I could just script it to chmod +x * afterwards, but surely there's a way to store permissions in SVN or to maintain them when you update? Any suggestions appreciated.

  • How can I define a method with multiple optional arguments in Obj-C

    - by The Dark Bug Returns
    I want to be able to update two sets of identical buttons with one function. Also I don't want to update all the buttons, only some of them. Can I have a function like this?: -(void) updateFields{ updateButton1 : (Bool) x updateButton2 : (Bool) y updateButton3 : (Bool) z } The implementation will look like this: [button1_1 setEnabled:x]; [button1_2 setEnabled:x]; //called only if updateButton1 is given an argument [button2_1 setEnabled:y]; etc...

  • Updating a sql server table with data from another table

    - by David G
    I have two basic SQL Server tables: Customer (ID [pk], AddressLine1, AddressLine2, AddressCity, AddressDistrict, AddressPostalCode) CustomerAddress(ID [pk], CustomerID [fk], Line1, Line2, City, District, PostalCode) CustomerAddress contains multiple addresses for the Customer record. For each Customer record I want to merge the most recent CustomerAddress record where most recent is determined by the highest CustomerAddress ID value. I've currently got the following: UPDATE Customer SET AddressLine1 = CustomerAddress.Line1, AddressPostalCode = CustomerAddress.PostalCode FROM Customer, CustomerAddress WHERE Customer.ID = CustomerAddress.CustomerID which works but how can I ensure that the most recent (highest ID) CustomerAddress record is selected to update the Customer table?

  • Updating table from async task android

    - by CantChooseUsernames
    I'm following this tutorial: http://huuah.com/android-progress-bar-and-thread-updating/ to learn how to make progress bars. I'm trying to show the progress bar on top of my activity and have it update the activity's table view in the background. So I created an async task for the dialog that takes a callback: package com.lib.bookworm; import android.app.ProgressDialog; import android.content.Context; import android.os.AsyncTask; public class UIThreadProgress extends AsyncTask<Void, Void, Void> { private UIThreadCallback callback = null; private ProgressDialog dialog = null; private int maxValue = 100, incAmount = 1; private Context context = null; public UIThreadProgress(Context context, UIThreadCallback callback) { this.context = context; this.callback = callback; } @Override protected Void doInBackground(Void... args) { while(this.callback.condition()) { this.callback.run(); this.publishProgress(); } return null; } @Override protected void onProgressUpdate(Void... values) { super.onProgressUpdate(values); dialog.incrementProgressBy(incAmount); }; @Override protected void onPreExecute() { super.onPreExecute(); dialog = new ProgressDialog(context); dialog.setCancelable(true); dialog.setMessage("Loading..."); dialog.setProgress(0); dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialog.setMax(maxValue); dialog.show(); } @Override protected void onPostExecute(Void result) { super.onPostExecute(result); if (this.dialog.isShowing()) { this.dialog.dismiss(); } this.callback.onThreadFinish(); } } And in my activity, I do: final String page = htmlPage.substring(start, end).trim(); //Create new instance of the AsyncTask.. new UIThreadProgress(this, new UIThreadCallback() { @Override public void run() { row_id = makeTableRow(row_id, layout, params, matcher); //ADD a row to the table layout. } @Override public void onThreadFinish() { System.out.println("FINISHED!!"); } @Override public boolean condition() { return matcher.find(); } }).execute(); So the above creates an async task to run to update a table layout activity while showing the progress bar that displays how much work has been done.. However, I get an error saying that only the thread that started the activity can update its views. I tried doing: MainActivity.this.runOnUiThread(new Runnable() { @Override public void run() { row_id = makeTableRow(row_id, layout, params, matcher); //ADD a row to the table layout. } } But this gives me synchronization errors.. Any ideas how I can display progress and at the same time update my table in the background? Currently my UI looks like:

  • Is there an easy way to "append()" two dictionaries together in Python?

    - by digitaldreamer
    If I have two dictionaries I'd like to combine in Python, i.e. a = {'1': 1, '2': 2} b = {'3': 3, '4': 4} If I run update on them it reorders the list: a.update(b) {'1': 1, '3': 3, '2': 2, '4': 4} when what I really want is attach "b" to the end of "a": {'1': 1, '2': 2, '3': 3, '4': 4} Is there an easy way to attach "b" to the end of "a" without having to manually combine them like so: for key in b: a[key]=b[key] Something like += or append() would be ideal, but of course neither works on dictionaries.

  • Any significance to Google's "expires" date being Fri, 01 Jan 1990 00:00:00 GMT?

    - by Robusto
    I was looking at the response headers for my GMail account and noticed that the date Fri, 01 Jan 1990 00:00:00 GMT shows up as the value for "Expires" over and over again. I suppose this is just an easy constant to make sure the browser understands this is past its freshness date. But is there any significance to that particular date? One might as easily have used the same date in 2000, or 1970, or whatever. It's not quirky enough to be someone's birthday or date of college graduation or anything personal like that. Maybe it's just arbitrary, but I was wondering if someone has a good explanation why that particular date was chosen.

  • How do you balance business process changes against the challenges of changing software?

    - by Achilles
    In my admittedly young career I've found myself writing code to support quirky business rules and processes. Inevitably these changes were always in some massively difficult code base and caused many issues. My question has a couple of parts: While software is a tool for businesses to make their lives easier, at what point do we as developers suggest a change in business process rather than in the software as the "magic bullet" to solve a particular problem. How do we as developers evangelize a certain level of reverence for the software as well as the difficulty involved in making changes simply to support the quirks of the business? I understand that these changes in business processes promote our industry, but in an analogy my father would understand: Which is easier, to melt down a hammer to forge a screwdriver to drive screws or to simply use nails since your hammer is already awesome...?

  • Detecting GWT RichTextArea 'dirty' state

    - by David
    I want to detect when the contents of my GWT RichTextArea become 'dirty' (have been changed by the user) in order to enable a 'save' button accordingly. I suppose I could listen for key presses that are likely to have changed the contents; but browser support for key presses is notoriously quirky. I suppose I could, before editing begins, save the original contents in a variable, and upon key press, compare the current contents against that variable, but doing that on each key press is going to be really slow. Is there some neat way to achieve RichTextArea dirty-detection?

  • Are there any good resources on developing ASP.NET for Windows CE Internet Explorer?

    - by IronicMuffin
    I've been tasked with creating a web app to be consumed by a mobile device sporting Windows CE 5.0 (and some with Windows CE 4.2). I've found a host of things that seem to work fine in IE6 on my desktop, but fail when rendered in IE for Windows CE. IE6 is bad enough as it is...does it lose any more functionality on an embedded system? Are there quirks that a developer would need to know about? AJAX seems extremely unlikely. JavaScript seems quirky when linking to a .js file. Panels with scrollbars are finicky. Textboxes can't get focus. DefaultButtons on a form don't work. Any help or resources you can provide would be greatly appreciated.

  • data structure for counting frequencies in a database table-like format

    - by user373312
    i was wondering if there is a data structure optimized to count frequencies against data that is stored in a database table-like format. for example, the data comes in a (comma) delimited format below. col1, col2, col3 x, a, green x, b, blue ... y, c, green now i simply want to count the frequency of col1=x or col1=x and col2=green. i have been storing the data in a database table, but in my profiling and from empirical observation, database connection is the bottle-neck. i have tried using in-memory database solutions too, and that works quite well; the only problem is memory requirements and quirky init/destroy calls. also, i work mainly with java, but have experience with .net, and was wondering if there was any api to work with "tabular" data in a linq way using java. any help is appreciated.

  • Mod_rewrite works on local, not on remote, version?

    - by TylerT
    I have this site. Let's call it htp://www.mysite.com I have a rewrite rule to change htp://www.mysite.com/?q=words%20etc/0/10 into http://www.mysite.com/words%20etc/0/10 (or http://www.mysite.com//0/10 or http://www.mysite.com/0/10) .htaccess:ErrorDocument 404 htp://www.mysite.com/404.html options +FollowSymlinks rewriteEngine on rewriteCond %{REQUEST_URI} !-f rewriteCond %{REQUEST_URI} !-d rewriteCond %{REQUEST_URI} !index\.php rewriteRule ^/?([^/]+?)?/?([0-9]+?)/([0-9]+?)$ index.php/%{THE_REQUEST} [NC] Now, this works on my local apache 2.2.11 server, no errors. However on my host's apache 1.3.41 server, I get the following error: [Sat Mar 5 21:42:14 2011] [alert] [client [ip]] /home/_/public_html/mysite.com/.htaccess: RewriteRule: cannot compile regular expression '^/?([^/]+?)?/?([0-9]+?)/([0-9]+?)$'\n I imagine it's something quirky about the apache version as other sites on this host use mod_rewrite without a hitch. I've tried removing the +followSymlinks line, even the rewrite engine line. I haven't tried removing the conditions cause I don't think I should have to, I'm probably wrong.

    Hi, The "python manage.py syncdb" command is giving me the following error: sqlite3.OperationalError: unable to open database file I'm following the step by step instructions in Practical Django Projects, so I think this has to do something with the Windows Operating system acting quirky! Things I've checkde: 1.The path is updated in settings.py is absolutely correcto! 2. Path is : C:\Documents and Settings\fixavier\Desktop\Django\Database\cms\cms.txt So the entire folder - Database, has sharing and security permissions. I'm pretty much at the bottom of the ocean for not being able to follow and successfully execute simple instructions, so could you please help me out here!

  • How does ruby allow a method and a Class with the same name?

    - by Daniel Beardsley
    I happened to be working on a Singleton class in ruby and just remembered the way it works in factory_girl. They worked it out so you can use both the long way Factory.create(...) and the short way Factory(...) I thought about it and was curious to see how they made the class Factory also behave like a method. They simply used Factory twice like so: def Factory (args) ... end class Factory ... end My Question is: How does ruby accomplish this? and Is there danger in using this seemingly quirky pattern?
