Tab bar controller inside a navigation controller, or sharing a navigation root view

- by Daniel Dickison

I'm trying to implement a UI structured like in the Tweetie app, which behaves as so: the top-level view controller seems to be a navigation controller, whose root view is an "Accounts" table view. If you click on any account, it goes to the second level, which has a tab bar across the bottom. Each tab item shows a different list and lets you drill down further (the subsequent levels don't show the tab bar). So, this seems like the implementation hierarchy is: UINavigationController Accounts: UITableViewController UITabBarController Tweets: UITableViewController Detail view of a tweet/user/etc Replies: UITableViewController ... This seems to work[^1], but appears to be unsupported according to the SDK documentation for -pushViewController:animated: (emphasis added): viewController: The view controller that is pushed onto the stack. It cannot be an instance of tab bar controller. I would like to avoid private APIs and the like, but I'm not sure why this usage is explicitly prohibited even when it seems to work fine. Anyone know the reason? I've thought about putting the tab bar controller as the main controller, with each of the tabs containing separate navigation controllers. The problem with this is that each nav controller needs to share a single root view controller (namely the "Accounts" table in Tweetie) -- this doesn't seem to work: pushing the table controller to a second nav controller seems to remove it from the first. Not to mention all the book-keeping when selecting a different account would probably be a pain. How should I implement this the Right Way? [^1]: The tab bar controller needs to be subclassed so that the tab bar controller's navigation item at that level stays in sync with the selected tab's navigation item, and the individual tab's table controller's need to push their respective detail views to self.tabBarController.navigationController instead of self.navigationController.

How do I copy a python function to a remote machine and then execute it?

- by Hugh

I'm trying to create a construct in Python 3 that will allow me to easily execute a function on a remote machine. Assuming I've already got a python tcp server that will run the functions it receives, running on the remote server, I'm currently looking at using a decorator like @execute_on(address, port) This would create the necessary context required to execute the function it is decorating and then send the function and context to the tcp server on the remote machine, which then executes it. Firstly, is this somewhat sane? And if not could you recommend a better approach? I've done some googling but haven't found anything that meets these needs. I've got a quick and dirty implementation for the tcp server and client so fairly sure that'll work. I can get a string representation the function (e.g. func) being passed to the decorator by import inspect string = inspect.getsource(func) which can then be sent to the server where it can be executed. The problem is, how do I get all of the context information that the function requires to execute? For example, if func is defined as follows, import MyModule def func(): result = MyModule.my_func() MyModule will need to be available to func either in the global context or funcs local context on the remote server. In this case that's relatively trivial but it can get so much more complicated depending on when and how import statements are used. Is there an easy and elegant way to do this in Python? The best I've come up with at the moment is using the ast library to pull out all import statements, using the inspect module to get string representations of those modules and then reconstructing the entire context on the remote server. Not particularly elegant and I can see lots of room for error. Thanks for your time

How can I get PowerShell Added-Types to use Added Types

- by Scott Weinstein

I'm working on a PoSh project that generates CSharp code, and then Add-Types it into memory. The new types use existing types in an on disk DLL, which is loaded via Add-Type. All is well and good untill I actualy try to invoke methods on the new types. Here's an example of what I'm doing: $PWD = "." rm -Force $PWD\TestClassOne* $code = " namespace TEST{ public class TestClassOne { public int DoNothing() { return 1; } } }" $code | Out-File tcone.cs Add-Type -OutputAssembly $PWD\TestClassOne.dll -OutputType Library -Path $PWD\tcone.cs Add-Type -Path $PWD\TestClassOne.dll $a = New-Object TEST.TestClassOne "Using TestClassOne" $a.DoNothing() "Compiling TestClassTwo" Add-Type -Language CSharpVersion3 -TypeDefinition " namespace TEST{ public class TestClassTwo { public int CallTestClassOne() { var a = new TEST.TestClassOne(); return a.DoNothing(); } } }" -ReferencedAssemblies $PWD\TestClassOne.dll "OK" $b = New-Object TEST.TestClassTwo "Using TestClassTwo" $b.CallTestClassOne() Running the above script gives the following error on the last line: Exception calling "CallTestClassOne" with "0" argument(s): "Could not load file or assembly 'TestClassOne,...' or one of its dependencies. The system cannot find the file specified." At AddTypeTest.ps1:39 char:20 + $b.CallTestClassOne <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException What am I doing wrong?

How do I convert an NSMutableString to NSString when using Frameworks?

- by BWHazel

I have written an Objective-C framework which builds some HTML code with NSMutableString which returns the value as an NSString. I have declared an NSString and NSMutableString in the inteface .h file: NSString *_outputLanguage; // Tests language output NSMutableString *outputBuilder; NSString *output; This is a sample from the framework implementation .m code (I cannot print the actual code as it is proprietary): -(NSString*)doThis:(NSString*)aString num:(int)aNumber { if ([outputBuilder length] != 0) { [outputBuilder setString:@""]; } if ([_outputLanguage isEqualToString:@"html"]) { [outputBuilder appendString:@"Some Text..."]; [outputBuilder appendString:aString]; [outputBuilder appendString:[NSString stringWithFormat:@"%d", aNumber]]; } else if ([_outputLanguage isEqualToString:@"xml"]) { [outputBuilder appendString:@"Etc..."]; } else { [outputBuilder appendString:@""]; } output = outputBuilder; return output; } When I wrote a text program, NSLog simply printed out "(null)". The code I wrote there was: TheClass *instance = [[TheClass alloc] init]; NSString *testString = [instance doThis:@"This String" num:20]; NSLog(@"%@", testString); [instance release]; I hope this is enough information!

Standard Apache (not OHS) with mod_osso for Single Signon

- by Markos Fragkakis

The mod_osso.so (the Apache plugin for Single Signon, provided by Oracle) is distributed with the Oracle HTTP Server (OHS), which is essentially a modified Apache. I am trying to use it on the standard Apache HTTP Server, and have not managed to get it to work. Configuration: Apache 2.2.15 OHS from the Oracle Web Tier Tools 11.1.1.2.0 Red Hat Linux 64 bit I have: Included the module in the modules directory (copied from corresponding modules dir in OHS) Included the libraries libiau.so and libclutsh.so.11.1 from Oracle Home. The absence of these libraries produced an error on starting Apache. Produced a osso.conf using the ssoreg.sh tool provided with OID (the LDAP implementation of Oracle) Created the required mod_osso.conf file, which I included in httpd.conf. The error I get when starting Apache is this: # /opt/apache_sso/bin/apachectl -k start httpd: Syntax error on line 1075 of /opt/apache_sso/conf/httpd.conf: Syntax error on line 1 of /opt/apache_sso/conf/mod_osso.conf: Cannot load /opt/apache_sso/modules/mod_osso.so into server: /opt/apache_sso/modules/mod_osso.so: undefined symbol: _audit_authentication_request My mod_osso.conf: # cat /opt/apache_sso/conf/mod_osso.conf LoadModule osso_module modules/mod_osso.so <IfModule mod_osso.c> OssoIdleTimeout off OssoIpCheck on OssoConfigFile conf/osso.conf #Location is the URI you want to protect <Location /myapp> require valid-user #OHS 11g AuthType Osso #OHS 10g AuthType Basic AuthType Osso </Location> </IfModule> Has anyone made mod_osso work on standard Apache HTTP server?

Convert ISO-8859-1 to UTF-8

- by tau

I have several documents I need to convert from ISO-8859-1 to UTF-8 (without the BOM of course). This is the issue though. I have so many of these documents (it is actually a mix of documents, some UTF-8 and some ISO-8859-1) that I need an automated way of converting them. Unfortunately I only have ActivePerl installed and don't know much about encoding in that language. I may be able to install PHP, but I am not sure as this is not my personal computer. Just so you know, I use Scite or Notepad++, but both do not convert correctly. For example, if I open a document in Czech that contains the character "ž" and go to the "Convert to UTF-8" option in Notepad++, it incorrectly converts it to an unreadable character. There is a way I CAN convert them, but it is tedious. If I open the document with the special characters and copy the document to Windows clipboard, then paste it into a UTF-8 document and save it, it is okay. This is too tedious (opening every file and copying/pasting into a new document) for the amount of documents I have. Any ideas? Thanks!!!

Accessing Yahoo realtime stock quotes

- by DVK

There's a fairly easy way of retrieving 15-minute delayed quotes off of Yahoo! Finance web site ("quotes.csv" API). However, so far I was unable to find any info on how to access real-time quotes. The hang-ups with real-time quotes are: Only available to logged-in user No API Non-obvious how to scrape the info - I'm somewhat convinced they are placed on the page by some weird Ajax call. So I was wondering if anyone had managed to develop a publically available solution to retrieve real-time quotes for a stock from Yahoo! Finance. Notes: Implementation language/framework need is flexible but Perl or Excel is highly preferred. Assume that security is not an issue - I'm willing to supply yahoo userid and pasword, even in cleartext. I'm not 100% hung up on Yahoo - they are merely the only provider of free realtime stock quotes I'm familiar with. if the same thing can be done with Google Finance, I'd be just as happy. This is for a personal project, so scalability/fault tolerance/etc... are not important. I'm looking for a "do the whole retrieval" library ideally, but if I'm pointed to partial solutions (e.g. how to retrieve info from Yahoo's user-logged-in pages; how to scrape realtime quotes from Yahoo's page) I can fill in the blanks. I saw Finance::YahooQuote but it does not seem to allow you to supply log-in information and appears to use the lagging quotes.csv API Thanks!

Obj-C component-based game architecture and message forwarding

- by WanderWeird

Hello, I've been trying to implement a simple component-based game object architecture using Objective-C, much along the lines of the article 'Evolve Your Hierarchy' by Mick West. To this end, I've successfully used a some ideas as outlined in the article 'Objective-C Message Forwarding' by Mike Ash, that is to say using the -(id)forwardingTargetForSelector: method. The basic setup is I have a container GameObject class, that contains three instances of component classes as instance variables: GCPositioning, GCRigidBody, and GCRendering. The -(id)forwardingTargetForSelector: method returns whichever component will respond to the relevant selector, determined using the -(BOOL)respondsToSelector: method. All this, in a way, works like a charm: I can call a method on the GameObject instance of which the implementation is found in one of the components, and it works. Of course, the problem is that the compiler gives 'may not respond to ...' warnings for each call. Now, my question is, how do I avoid this? And specifically regarding the fact that the point is that each instance of GameObject will have a different set of components? Maybe a way to register methods with the container objects, on a object per object basis? Such as, can I create some kind of -(void)registerMethodWithGameObject: method, and how would I do that? Now, it may or may not be obvious that I'm fairly new to Cocoa and Objective-C, and just horsing around, basically, and this whole thing may be very alien here. Of course, though I would very much like to know of a solution to my specific issue, anyone who would care to explain a more elegant way of doing this would additionally be very welcome. Much appreciated, -Bastiaan

Incorporating the Windows 7 onscreen keyboard into a WPF app

- by mmr

Windows 7 has a really nice onscreen keyboard program/control for touchscreens. I have a touchscreen app that was originally written for, and will be deployed on, XP. Is it possible to incorporate this keyboard directly into my app, rather than me using a custom control? I can find no programmatic information about it, so any links would be very helpful. Specifically, I'd need: To be able to use the keyboard on an XP machine that will have .NET 3.5 sp1 installed on it. To be able to hide the native keyboard on Windows 7, because I've already incorporated the touchscreen keyboard in my UI and so I don't need another one cluttering up the UI. This native keyboard has two attractive aspects to it. First off, it's automatically localized to the customer's language (though the rest of the app will need modification), and second off, it doesn't seem to suffer from 'touch lag' as the OS tries to figure out whether or not I'm doing a gesture, because I'm clearly typing on a keyboard. The app is WPF based, which should mean easy integration with Windows 7 based controls. EDIT: I'd really like the XP thing, but it's not a requirement. The ability to use the keyboard in Win7, though, seems like it should be possible and even the right way to do it.

How do you prove your cleverness and programming skills?

- by Sebi

Lately, there were a lot of questions related to career planning and how to decide which languages to learn, how to learn new languages and so on. But I was thinking about a way, how do you will proof later that you're really learned something. Ok you can mentione it in your application for a job or in the interview, but by just stating that I was learning e.g. C++ at home, I don't think this will really be very sucessful. So some suggested to create something (homepage, application, whatsoever) to prove that you also can use these skills in practice. But still I'm not really sure if this will provide any benefit, because it would require a very special project to show all your skills and I don't think you can easily invent such a project (that sould also be useful). Others suggested to solve for example the Project Euler questions but still I'm not sure how this will be useful in career-planning. Are you going to mention at your job interview that you solved all this question in the company's favorite programming language?? :D I can't imagine. The reason why I'm asking is that I have some spare time and I would really like to learn some new programming languages (C++ and/or Python if this matters) and I'm looking for a smart way to do is while concurrently assure that it will be useful in my future career. (there are 3-4 companies id like to try to get a job andIi know all of them are using mainly C++/Pyhton...)

C# Check if character exists in encoding

- by Alvin Wong

I am writing a program that a part renders a bitmap font in CP437. In a function that renders the text with I want to be able to check whether a char is available in CP437 before the encoding conversion, like: public static void DrawCharacter(this Graphics g, char c) { if (char_exist_in_encoding(Encoding.GetEncoding(437), c) { byte[] src = Encoding.Unicode.GetBytes(c.ToString()); byte[] dest = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(437), src); DrawCharacter(g, dest[0]); // Call the void(this Graphics, byte) overload } } Without the check, any characters outside CP437 will result in a '?' (63, 0x3F). I want to hide any invalid characters completely. Is there an implementation of char_exist_in_encoding other than the following stupid approach? public static bool char_exist_in_encoding(Encoding e, char c) { if (c == '?') return true; byte[] src = Encoding.Unicode.GetBytes(c.ToString()); byte[] dest = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(437), src); if (dest[0] == 0x3F) return false; return true; } Perhaps not very relevant, but the bitmap is created like this: Bitmap b = new Bitmap(256 * 8, 16); Graphics g = Graphics.FromImage(b); g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SingleBitPerPixelGridFit; Font f = new Font("Whatever 8x16 bitmap font", 16, GraphicsUnit.Pixel); for (byte i = 0; i < 255; i++) { byte[] arr = Encoding.Convert(Encoding.GetEncoding(437), Encoding.Unicode, new byte[] { i }); char c = Encoding.Unicode.GetChars(arr)[0]; g.DrawString(c.ToString(), f, Brushes.Black, i * 8 - 3, 0); // Don't know why it needs a 3px offset } b.Save(@"D:\chars.png");

I am trying to do that by the following code: ... /** Creating canvas. */ GLCapabilities capabilities = new GLCapabilities(); capabilities.setDoubleBuffered(true); GLCanvas canvas = new GLCanvas(capabilities); ... /** Function display(…), which draws a white Rectangle on a black background. */ public void display(GLAutoDrawable drawable) { drawable.swapBuffers(); gl = drawable.getGL(); gl.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT); gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); gl.glColor3f(1.0f, 1.0f, 1.0f); gl.glBegin(GL.GL_POLYGON); gl.glVertex2f(-0.5f, -0.5f); gl.glVertex2f(-0.5f, 0.5f); gl.glVertex2f(0.5f, 0.5f); gl.glVertex2f(0.5f, -0.5f); gl.glEnd(); } ... /** Other functions are empty. */ Questions: — When I'm resizing the window, I usually get flickering. As I see it, I have a mistake in my double buffering implementation. — I have doubt, where I must place function swapBuffers — before or after (as many sources says) the drawing? As you noticed, I use function swapBuffers (drawable.swapBuffers()) before drawing a rectangle. Otherwise, I'm getting a noise after resize. So what is an appropriate way to do that? Including or omitting the line capabilities.setDoubleBuffered(true) does not make any effect.

Using Nemerle in asp.net App_Code directory

I want to use Nemerle in an ASP.NET application. Specifically, putting .n files into App_Code.

Styling columns based on DataGridTemplateColumn in a WPF DataGrid

- by nareshbhatia

I am using a WPF DataGrid where one of the columns has a requirement to show an "Edit" hyperlink if the row is editable - this is indicated by a boolean flag in the backing model for the row. I was able to achieve this using a DataGridTemplateColumn - no problems. However an additional requirement on the entire row is not to show any highlights when the row is selected (this is a blue background by default). I have been able to achieve this on other columns by defining the DataGridCell style with a transparent background, e.g. <DataGridTextColumn Header="Id" Binding="{Binding Path=Id}" HeaderStyle="{StaticResource DataGridColumnHeaderStyle}" CellStyle="{StaticResource DataGridCellStyle}" /> where DataGridCellStyle is defined as follows: <Style x:Key="DataGridCellStyle" TargetType="{x:Type DataGridCell}"> <Setter Property="Background" Value="Transparent" /> ... </Style> However the column in question, a DataGridTemplateColumn, does not offer a "CellStyle" attribute which I can use for turning off selection highlights. So my question is how to set the cell style when using a DataGridTemplateColumn? Here's my implementation of the column which satisfies the first requirement (i.e. showing an "Edit" hyperlink if the row is editable): <DataGridTemplateColumn Header="Actions" HeaderStyle="{StaticResource CenterAlignedColumnHeaderStyle}"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Visibility="{Binding Path=Editable, Converter={StaticResource convVisibility}}" Style="{StaticResource CenterAlignedElementStyle}"> <Hyperlink Command="..." CommandParameter="{Binding}"> <TextBlock Text="Edit" /> </Hyperlink> </TextBlock> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> Thanks.

Android Share - Facebook SDK - ShareActionProvider

- by Vlasto Benny Lava

I am trying to implement sharing a simple string inside my application. Obviously everything other than Facebook works. As far as I know, now I have to use their Facebook SDK to post statuses on a wall. However, if I do implement it using their SDK, is there a way to have it incorporated into the chooser (default or ShareActionProvider) and somehow override it and insert the Facebook SDK's implementation? Or do I have to create a dedicated button? //EDIT package com.example.shareactionproviderdemo; import android.app.Activity; import android.content.Intent; import android.os.Bundle; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Intent sharingIntent = new Intent(Intent.ACTION_SEND); sharingIntent.setType("text/plain"); sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Test message"); startActivity(Intent.createChooser(sharingIntent, "Share using")); } }

Passing binary blob through an Android content provider

- by velocityb0y

I have a content provider that is custom to my set of Android applications, and one of the things it needs to expose is a small (20-30k) byte array. The uri for these blobs looks like content://my.authority/blob/# where # is the row number; the resulting cursor has the standard _id column and a data column. I'm using a MatrixCursor in the provider's query method: byte[] byteData = getMyByteData(); MatrixCursor mc = new MatrixCursor(COLUMNS); mc.addRow(new Object[] { id, byteData }); Later, in the application consuming the data, I do Cursor c = managedQuery(uri, null, null, null, null); c.moveToFirst(); byte[] data = c.getBlob(c.getColumnIndexOrThrow("data")); However, data does not contain the contents of my original byte array; rather, it contains something like "[B@435cc518", which looks more like the address of the array than the contents. I tried wrapping the byte array in an implementation of java.sql.Blob, figuring that it might be looking for that since the content provider subsystem was written to be easy to use with SQLite, but it didn't help. Has anyone gotten this to work? If the data was in the file system, there are methods in ContentProvider that I could use to provide a marshalled InputStream to the client, but the data I'm trying to send back lives as a resource in the content provider's APK.

consistency of Trigger Procedure (before row trigger) Postgresql

- by elgcom

Using Postgresql. I try to use TRIGGER procedure to make some consistency check on INSERT. The question is ...... whether "BEFORE INSERT FOR EACH ROW" can make sure each row to insert "checked" and "inserted" one after another? do I need extra lock on table to survive from concurrent insert? check for new row1 - insert row1 - check for new row2 - insert row2 -- -- -- unexpired product name is unique. CREATE TABLE product ( "name" VARCHAR(100) NOT NULL, "expired" BOOLEAN NOT NULL ); CREATE OR REPLACE FUNCTION check_consistency() RETURNS TRIGGER AS $$ BEGIN IF EXISTS (SELECT * FROM product WHERE name=NEW.name AND expired='false') THEN RAISE EXCEPTION 'duplicated!!!'; END IF; RETURN NEW; END; $$ LANGUAGE plpgsql; CREATE TRIGGER trigger_check_consistency BEFORE INSERT ON product FOR EACH ROW EXECUTE PROCEDURE check_consistency(); -- INSERT INTO product VALUES("prod1", true); INSERT INTO product VALUES("prod1", false); INSERT INTO product VALUES("prod1", false); // exception! this is OK name | expired ============== p1 | true p1 | true p1 | false This is not OK name | expired ============== p1 | true p1 | false p1 | false or maybe I should ask, how can I use Trigger to implement "Primary" or "Unique" constraint-like SQL.

Using a dynamic <script> (a <script> appended to the DOM by JavaScript) to load and initialize Click

- by Bungle

I'm creating an HTML/JavaScript widget to be used on third-party sites. This widget is generated by a <script> that our customers will insert on their page. The <script> creates an <iframe> in the customer's domain, and then creates and inserts all of that <iframe>'s content using JavaScript. It's important that this <iframe> contain Clicky's tracking code to monitor clicks on outbound links. Unfortunately, I'm not having any luck getting Clicky to work when I append the requisite <script> elements to the <iframe> using JavaScript. I first tried simply appending the Clicky tracking code to the <iframe> after appending some test outbound links, hoping that Clicky could attach to those automatically as it does on a static page. That didn't seem to work, so my next inclination was to use the "advanced_disable" custom option and use clicky.log() on the links I want to track. Here's a link to a test page that's along those lines: http://onespot.wsj.com/static/clicky_iframe_test.html When clicking a link on that test page, the action is not logged in Clicky, and a JavaScript error appears: clicky is not defined This ("clicky") appears to be defined in http://static.getclicky.com/js, which I confirmed through the Firebug console is indeed loading before I click a test outbound link. Has anyone successfully loaded Clicky in this way? If so, could you provide some sample code, a link to a working implementation, or some feedback on what's wrong with my code? I would also be interested to know if this is even possible. Thanks very much for any help or advice!

Height of a html window's content (not just the viewport height)

- by gatapia

Hi All, I'm trying to get the height of a html window's content. This is the full height of the content not the visible height. I have had some (very limited) success using: document.getElementsByTagName('html')[0].offsetHeight in FireFox. This however fails in IEs and it fails in Chrome when using absolute positioned elements (http://code.google.com/p/chromium/issues/detail?id=38999). A sample html file that can be used to reproduce this is: <html> <head> <style> div { border:solid 1px red; height:2000px; width:400px; } .broken { position:absolute; top:0; left:0; } .fixed { position:relative; top:0; left:0; } </style> <script language='javascript'> window.onload = function () { document.getElementById('window.height').innerHTML = window.innerHeight; document.getElementById('window.screen.height').innerHTML = window.screen.height; document.getElementById('document.html.height').innerHTML = document.getElementsByTagName('html')[0].offsetHeight; } </script> </head> <body> <div class='fixed'> window.height: <span id='window.height'> </span> <br/> window.screen.height: <span id='window.screen.height'></span> <br/> document.html.height: <span id='document.html.height'></span> <br/> </div> </body> </html> Thanks All Guido Tapia
