• The reasons to upgrade from Delphi 2009

  - by Serg

  I have made the question "community wiki" - it is subjective. I have upgraded to Delphi 2009 because of unicode support. I have found the anonymous methods a very interesting and useful language feature, I can't say the same about generics. The generics seemed important for me before the upgrade to Delphi 2009, but I have never used them and probably will never use. As for Delphi 2010, I don't need the attributes and I don't like the whole idea of extended RTTI - that is why Delphi 2009 is better for me. Sometimes I hit one or other annoying bug in Delphi 2009 IDE, but they are not critical and I can live with them. I have no plans to develop software for Mac or Linux. Sure sometime I will need 64-bit support, so I think about upgrading to Delphi 2012. Are where any more reasons that can force me to upgrade from Delphi 2009?

• Is there a way to undo Mocha stubbing of any_instance in Test::Unit

  - by Craig Walker

  Much like this question, I too am using Ryan Bates's nifty_scaffold. It has the desirable aspect of using Mocha's any_instance method to force an "invalid" state in model objects buried behind the controller. Unlike the question I linked to, I'm not using RSpec, but Test::Unit. That means that the two RSpec-centric solutions there won't work for me. Is there a general (ie: works with Test::Unit) way to remove the any_instance stubbing? I believe that it's causing a bug in my tests, and I'd like to verify that.

• Magic behind R.java file

  - by LambergaR

  Hi! Recently I have been having quite some problems with R.java file. Now I have decided to do a backup and delete the file to see what happens. Nothing happened, so I created an empty R.java file and hopped for the best. Now Eclipse seems to figure out that the file was tempered with and even issues a warning: R.java was modified manually! Reverting to generated version! And that's all there is. I tried building it manually but got no results. So, I have two questions: 1. what should I do to force Eclipse to generate the file 2. what is happening here? How is the file created, where is the code that is generating the file? I would appreciate any help. As usual the problem occurred just a few days before the deadline :)

• Yield In VB.NET

  - by MagicKat

  C# has the keyword called yield. VB.NET lacks this keyword. I am curious how some of the VB programmers have gotten around the lack of this keyword. Do you implement your own iterator class? Or do you try and code to avoid the need of an iterator? The yield keyword does force the compiler to do some coding behind the scenes. http://blogs.msdn.com/oldnewthing/archive/2008/08/12/8849519.aspx is a good example of that.

• How to effectively measure developer's work hours?

  - by twk

  I have a few software developers working for my projects and I would like to provide them a way to register time they spent on real development. There is good will to register development hours, no force, but we try to avoid techniques like excel sheets register because this is so uncomfortable. I can track svn commits, but this is unreliable. Developers also helps supporting different projects during the day, so assuming they work on one project by whole day is not true. I've seen utilities that popups a message every hour to confirm the project you're working on but this is annoying. Some kind of active-window-title-anaylzer might help (you can get solution name from there in the case of Visual Studio) but I have no experience with such idea. If you have any experience with programmers/designers work hours registration, please share with me. Thanks

• .NET - downloading multiple pages from a website with a single DNS query

  - by lampak

  I'm using HttpRequest to download several pages from a website (in a loop). Simplifying it looks like this: HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create( "http://sub.domain.com/something/" + someString ); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); //do something I'm not quite sure actually but every request seems to resolve the address again (I don't know how to test if I'm right). I would like to boost it a little and resolve the address once and then reuse it for all requests. I can't work out how to force HttpRequest into using it, though. I have tried using Dns.GetHostAddresses, converting the result to a string and passing it as the address to HttpWebRequest.Create. Unfortunately, server returns error 404 then. I managed to google that's probably because the "Host" header of the http query doesn't match what the server expects. Is there a simple way to solve this?

• setsockopt TCP_NODELAY question on Windows Mobile

  - by weki

  Hi all, I have a problem on Windows Mobile 6.0. I would like to create a TCP connection which does not use the Nagle algorithm, so it sends my data when I call "send" function, and does not buffer calls, having too small amount of data. I tried the following: BOOL b = TRUE; setsockopt(socketfd, IPPROTO_TCP, TCP_NODELAY, (char*)(&b), sizeof(BOOL)); It works fine on desktop. But on Windows Mobile, if I set this value, than I make a query for it, the returned value is 8. And the network traffic analysis shows that the nothing changed. Is there any way to force a flush to my socket?

• SharpSSH gets stuck in an infinite stream read in C# SSH app

  - by Ric Coles

  Afternoon all, I'm having a small problem with the SharpSSH library for .Net (see http://www.tamirgal.com/blog/page/SharpSSH.aspx) SshStream ssh = new SshStream("some ip address", "some username", "some password"); ssh.Prompt = "\n"; ssh.RemoveTerminalEmulationCharacters = true; ssh.Write("ssh some ip address"); // Don't care about this response ssh.ReadResponse(); ssh.Write("lss /mnt/sata[1-4]"); // Don't care about this response (for now) ssh.ReadResponse(); // while the stream can be read while (ssh.CanRead) { Console.WriteLine(ssh.ReadResponse()); } ssh.Close(); As you can see, it's fairly straight forward. However, when the while-loop gets stepped into, it won't break out of the loop when everything has been printed to the console and there is nothing else to read. Is there anyway I can manually force it to break when there is nothing else to be read? Cheers, Ric

• Initialization of std::vector<unsigned int> with a list of consecutive unsigned integers

  - by Thomas

  I want to use a special method to initialize a std::vector<unsigned int> which is described in a C++ book I use as a reference (the German book 'Der C++ Programmer' by Ulrich Breymann, in case that matters). In that book is a section on sequence types of the STL, referring in particular to list, vector and deque. In this section he writes that there are two special constructors of such sequence types, namely, if Xrefers to such a type, X(n, t) // creates a sequence with n copies of t X(i, j) // creates a sequence from the elements of the interval [i, j) I want to use the second one for an interval of unsigned int, that is std::vector<unsigned int> l(1U, 10U); to get a list initialized with {1,2,...,9}. What I get, however, is a vector with one unsigned int with value 10 :-| Does the second variant exist, and if yes, how do I force that it is called?

• Ending php sessions for debugging purposes

  - by Bill Zimmerman

  Hi, This might be very easy to do, but I haven't been able to figure it out. Basically, I have a loosely couple web-app written in python and php. The python code uses PHP sessions (generated from the PHP app when the user logs in) to check if the user is logged in/has permission to access the given python resource. My question is this: What is the easiest way to force all active sessions to timeout. I would like to do this for debugging purposes, to test out the python code. I tried changing the session.max_lifetime PHP variable, but that still doesn't guarantee that the session has ended and is removed. I tried just deleting the file, but this seems to cause problems (when i refresh the php page, errors show up in my apache logs and it won't reload quickly) Any ideas?

• Difference between dates

  - by Ben C

  I want to calculate the difference between two times, one of which is the current time, and the other is just in the format HH:MM, always in the future. If I just subtract $futuretime from $now, it should, of course, be a positive number. This works fine until... If $now is in the afternoon or evening and $futuretime is, say, 7AM next morning, how can I force it to understand the the time is always going to be in the future? (It's for working out the time of something that occurs about every half an hour during working hours, and then stops until the following morning) Thanks in advance!

• SSIS - How do I see/set the field types in a Recordset?

  - by thursdaysgeek

  I'm looking at an inherited SSIS package, and a stored procedure is sending records to a recordset called USER:NEW_RECORDS. It's of type Object, and the value is System.Object. It is then used for inputting that data to a SQL table. We're getting an error, because it seems that the numeric results of the stored procedure are being put in a DT_WSTR field, and then failing when it is then put into a decimal field in the database. Most of the records are working, but one, which happens to have a longer number of decimal digits, is failing. I want to see exactly what my SSIS recordset field types are, and probably change them, so I can force the data to be truncated properly and copied. Or, perhaps, I'm not even looking at this correctly. The data is put into the recordset using a SQL Task that executes the stored procedure.

• Weblogic server 10.0 - Managed Server shutting down

  - by Eqbal

  We have a weblogic server 10.0 instance which has a cluster with one managed server. Every Monday at 5am (or few seconds after), it shuts down on its own. The logs do not show any errors except the following message: JVM called WLS shutdown hook. The server will force shutdown now. JVM has a -Xnohup option and using JRockit. There is no cron job on the server. I am not sure how to debug this one. Admin Server keeps running with no issues and I am able to start the managed server back up with no problems. Any help is greatly appreciated. Thanks.

• How can I skip the current item and the next in a Python loop?

  - by uberjumper

  This might be a really dumb question, however I've looked around online, etc. And have not seen a solid answer. Is there a simple way to do something like this? lines = open('something.txt', 'r').readlines() for line in lines: if line == '!': # force iteration forward twice line.next().next() <etc> It's easy to do in C++; just increment the iterator an extra time. Is there an easy way to do that in Python? I would just like to point, out the main purpose of this question is not about "reading files and such" and skipping things. I was more looking for C++ iterator style iteration. Also the new title is kinda dumb, and i dont really think it reflects the nature of my question.

• Keyboard in HTML text-input disappear when WebView call 'loadUrl' again

  - by Jr.

  Hi there, I use WebView for my Androind App. I got a problem and request a solution for help. There is a textfield in the HTML page. When it gets 'focus' and then I call mWebView.setFocusableInTouchMode(true); in Java code so that the Android soft-keyboard will pop-up to let me key in. The problem is I need using multi-thread for some processes in Java and call mWebView.loadUrl(strJSCall); as callback to execute JavaScript function, but the keyboard gets hidden! The way I try is to force the keyboard to show again. But how can the keyboard always show when 'loadUrl' is called? Dose anyone meet the same issue and solve it already? Sincerely, Jr.

• How can I make a steady automata in JavaScript?

  - by RobertWHurst

  I'm working on a JavaScript game and I've got an automata system controlling game time and sprite animation as well as giving a hand to the path finding system for timing and such. My problem is on slow browsers the JavaScript loop I'm using for counting the time is not very accurate. It tends to jump around a lot. I there a way to force the loop to run consistently at 30 fps? The automata can drop frames if it needs to catch up so if the solution requires dropping frames that's ok.

• OpenType programming

  - by Sorush Rabiee

  Hi all Recently i asked two questions (1 and 2) about using OpenType features in programs written by python and .net languages, but didn't get an answer. i realized there is no way to change text rendering engines of operating systems, or force them to use OpenType. so now want to implement my own. such a program that: provides a text engine that receives glyph shapes from otf and ttf files and renders them in sequence of glyphs in text. generates all of OTL features can be used in other parts of applications like controls and components of .NET or python GUI libraries. if python and .net languages are not suitable in this situation, aware me about other programming languages or tools. comments and answers about text rendering system of common Operating Systems, or designing text engines compatible with unicode 5.02 protocol are welcomed.

• How to deserialize null array to null in c#?

  Here is my class: public class Command { [XmlArray(IsNullable = true)] public List<Parameter> To { get; set; } } When I serialize an object of this class: var s = new XmlSerializer(typeof(Command)); s.Serialize(Console.Out, new Command()); it prints as expected (xml header and default MS namespaces are omitted): <Command><To xsi:nil="true" /></Command> When I took this xml and tried to deserialize it I got stucked, because it always print "Not null": var t = s.Deserialize(...); if (t.To == null) Console.WriteLine("Null"); else Console.WriteLine("Not null"); How to force deserializer to make my list null, if it is null in xml?

• compare previous ENCRYPT() call with new ENCRYPT() call mysql

  - by contagious

  I'm storing a string in mysql with the ENCRYPT() function. I want to fetch a row where that string is matched, but the new ENCRYPT() call gives me a different value, so they never match. This is expected as i'm not (and can't) give it a consistent salt: http://dev.mysql.com/doc/refman/5.0/en/encryption-functions.html#function_encrypt If no salt argument is given, a random value is used. This is the query i'm running that returns empty: SELECT * FROM `table` WHERE ENCRYPT('string') = `enc_string` I know this is possible because this is used by a 3rd party app, but I can't find their query where they do this. Is there a way to force ENCRYPT to use the previous salt, or predict it?

• What's the right way to kill child processes in perl before exiting?

  - by rarbox

  I'm running an IRC Bot (Bot::BasicBot) which has two child processes running File::Tail but when exiting, they don't terminate. So I'm killling them using Proc::ProcessTable like this before exiting: my $parent=$$; my $proc_table=Proc::ProcessTable->new(); for my $proc (@{$proc_table->table()}) { kill(15, $proc->pid) if ($proc->ppid == $parent); } It works but I get this warning: 14045: !!! Child process PID:14047 reaped: 14045: !!! Child process PID:14048 reaped: 14045: !!! Your program may not be using sig_child() to reap processes. 14045: !!! In extreme cases, your program can force a system reboot 14045: !!! if this resource leakage is not corrected. What else can I do to kill child processes? The forked process is created using the forkit method in Bot::BasicBot.

• Silverlight 4 Out-of-browser application into the browser ?

  - by Niklaos

  Hi guys, I just lost 5 hours looking for a answer which i haven't been able to find :p First, I'd like to force a trusted application (i need to access the file system) to display into the browser. Based on what i found on google a trusted application must be installed and launched as a desktop application (also called out-of-browser application). So, i want to have an installed application on the client side but meanwhile, the user must also be able to start this same application into a browser window when he goes on my web site. Is this possible ? Second, I'd like to give to the user the possibility to start the application from the browser. To be clear be the application is installed on the client computer but i want a button on my web site which starts the desktop application. How can i do that ? Thanks

• Using bash shell from within PHP

  - by Dan

  Hi everyone, In my terminal window (using Max OS X) my shell is bash. However when I run a command in PHP via shell_exec or backtick operators I see that PHP is using the Bourne Shell (sh). Here's an example of what I'm seeing: From within my terminal window: $ echo $0 - bash Also if I call php as follows: $ php -r "echo shell_exec('echo $0');" -bash However, if I create a script called test.php with the following: <?php echo shell_exec('echo $0'); ?> And then run test php I get the following: $ php test.php sh I'm wanting to use the bash shell when calling shell_exec - why is it choosing the Bourne shell and can I force it to use bash? Thanks! Dan

• Are there macro facility for Java or C#?

  - by h2g2java

  Macros are useful. Therefore, I occasionally bemoan the absence of macros in Java and C#. Macros allow me to force in-line but allow me the code-manageability of non-macro code. Is there any Java- or C#-based project/product somewhere out there that effectively allow macros or specifying in-line expansion. I am thinking of something like @macro public void hello(int x){ ... } or when I call a method, an @inline annotation preceding the call would effect the called-method to be in-lined. or, should I need to know that I should just trust the compiler to make the best the decision for me that at the best of its analysis it might in-line a call. I hope this question will not lead to debating the pro/cons/usefulness of macros.

• Firefox adds <br> when paste from Word in TinyMCE

  - by Rakward

  I'm currently using TinyMCE 3.3 on a drupal site, with an annoying problem. Using both "paste from word"-button or "Force cleanup on paste" in Firefox cause TinyMCE to insert line-breaks in my paragraphs where the line would have ended in Word. In IE, I do not have this problem. When viewing the source code in the editor, it doesn't show a -tag, but an actual line-break. When viewing the normal text in the editor, I see no linebreak at all, but on saving, it's really there when viewing the page. Even in the beginning of every first line of every paragraph it insert a linebreak. How do I solve this?? "Remove linebreaks" isn't an option, since people want to insert linebreaks to create some vertical spacing.
