  • Send a empty Message or Notification with MVVM toolkit light

    - by msfanboy
    Hello Laurent ;-) I could not find any Ctor of Messenger or Notification class to send a empty message. ViewModel1: private int _selectedWeeklyRotation; public int SelectedWeeklyRotation { get { return _selectedWeeklyRotation; } set { if(_selectedWeeklyRotation == value) return; _selectedWeeklyRotation = value; this.OnPropertyChanged("SelectedWeeklyRotation"); if(value > 1) Messenger.Default.Send(); } } ViewModel2: Ctor: Messenger.Default.Register(this, CreateAnotherTimeTable); private void CreateAnotherTimeTable() { } I just need to send a Notification to another ViewModel, no sending of data at all. Is that possible with mvvm light toolkit library?

  • How do I retrieve program output in Python?

    - by Geoff
    I'm not a Perl user, but from this question deduced that it's exceedingly easy to retrieve the standard output of a program executed through a Perl script using something akin to: $version = `java -version`; How would I go about getting the same end result in Python? Does the above line retrieve standard error (equivalent to C++ std::cerr) and standard log (std::clog) output as well? If not, how can I retrieve those output streams as well? Thanks, Geoff

  • Django DecimalField returns "None" instead of empty value

    - by Ed
    Is there a way to force django to display nothing instead of "None" for a Decimal Field that's been left blank? In my template, I show a list of all the values for a particular field. Each value is hyperlinked to a page that displays the results of a query filtered on that value. But because there are some entries with null value, my list includes actual DecimalField entries and "None" for all those that are empty. When a user clicks on None, django throws a validation error because you cannot query a DecimalField using a string. I could write if statements checking all instances of decimal fields for Nones and skipping them, but that is far from an elegant solution. Any advice? This is one part of the code, though there are other templates that derive the None value in slightly different manners: {% for item in choices %} <a href={% url app_views.field_choice item %}>{{ item }}</a><br> {% endfor %}

  • Default input and output buffering for fopen'd files?

    - by Evan Teran
    So a FILE stream can have both input and output buffers. You can adjust the output stream using setvbuf (I am unaware of any method to play with the input buffer size and behavior). Also, by default the buffer is BUFSIZ (not sure if this is a POSIX or C thing). It is very clear what this means for stdin/stdout/stderr, but what are the defaults for newly opened files? Are they buffered for both input and output? Or perhaps just one? If it is buffered, does output default to block or line mode?

  • Php writing to file - empty ?

    - by The Devil
    Hey, I've been struggling with writing a single string into a file. I'm using just a simple code under Slackware 13: $fp = fopen('/my/absolute/path/data.txt', 'w'); fwrite($fp, 'just a testing string...'); fclose($fp); The file gets created (if it's not already created) but it's empty ?! The directory in which this file is written is owned by apache's user & group (daemon.daemon) and has 0777 permissions. This has never happened to me before. I'm curious what's the reason I'm not able to write inside the file ? Thanks in advance.

  • Ruby: output not saved to file

    - by Sophie
    I'm trying to give a file as input, have it changed within the program, and save the result to a file that is output. But the output file is the same as the input file. :/ Total n00b question, but what am I doing wrong?: puts "Reading Celsius temperature value from data file..." num = File.read("temperature.dat") celsius = num.to_i farenheit = (celsius * 9/5) + 32 puts "Saving result to output file 'faren_temp.out'" fh = File.new("faren_temp.out", "w") fh.puts farenheit fh.close

  • Remove empty subfolders with PHP

    - by Dmitry Letano
    I am working on a PHP function that will recursively remove all sub-folders that contain no files starting from a given absolute path. Here is the code developed so far: function RemoveEmptySubFolders($starting_from_path) { // Returns true if the folder contains no files function IsEmptyFolder($folder) { return (count(array_diff(glob($folder.DIRECTORY_SEPARATOR."*"), Array(".", ".."))) == 0); } // Cycles thorugh the subfolders of $from_path and // returns true if at least one empty folder has been removed function DoRemoveEmptyFolders($from_path) { if(IsEmptyFolder($from_path)) { rmdir($from_path); return true; } else { $Dirs = glob($from_path.DIRECTORY_SEPARATOR."*", GLOB_ONLYDIR); $ret = false; foreach($Dirs as $path) { $res = DoRemoveEmptyFolders($path); $ret = $ret ? $ret : $res; } return $ret; } } while (DoRemoveEmptyFolders($starting_from_path)) {} } As per my tests this function works, though I would be very delighted to see any ideas for better performing code.

  • Django - Empty session data in ajax requests

    - by ninja123
    Hi guys, I have an ajax view where I want to set a session variable like such: def upload(request, *args, **kwargs): request.session['test'] = 'test' request.session.modified = True print request.session.items() I have another normal view something like this: def advertise(request): print request.session.items() I get these two strings printed to shell: [('test', 'test')] [('_auth_user_backend', 'django.contrib.auth.backends.ModelBackend'), ('_auth_user_id', 26L)] Why is the session data that I set in the ajax view not passing to my regular views? If I set session data in regular view, everything works as fine, but it seems that ajax requests contain empty session data? Anybody dealt with something like this before? Any suggestions are greatly appreciated. Thanks.

  • How can I set the buffer size for the underneath Socket UDP? C#

    - by Jack
    Hi all As we know for UDP receive, we use Socket.ReceiveFrom or UdpClient.receive Socket.ReceiveFrom accept a byte array from you to put the udp data in. UdpClient.receive returns directly a byte array where the data is My question is that How to set the buffer size inside Socket. I think the OS maintains its own buffer for receive UDP data, right? for e.g., if a udp packet is sent to my machine, the OS will put it to a buffer and wait us to Socket.ReceiveFrom or UdpClient.receive, right? How can I change the size of that internal buffer? I have tried Socket.ReceiveBuffSize, it has no effect at all for UDP, and it clearly said that it is for TCP window. Also I have done a lot of experiments which proves Socket.ReceiveBufferSize is NOT for UDP. Can anyone share some insights for UDP internal buffer??? Thanks

But now when I submit the form, the hidden field values are still empty. Do you have any idea whats going wrong? Thx for your answers.

  • How to read output of android process command

    I am trying to get the output of android shell command 'getprop' with java since getprop() always returns null no matter what. I tried this from developer.android.com: Process process = null; try { process = new ProcessBuilder() .command("/system/bin/getprop", "build.version") .redirectErrorStream(true) .start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } InputStream in = process.getInputStream(); //String prop = in.toString(); System.out.println(in); process.destroy(); However what is printed is not the output but a bunch of characters and numbers (dont have the exact output right now). How can i get the output of the process? Thanks!

  • How do I change which audio jacks are used for input and output?

    - by yamaha1996
    I'm using a Realtek HD audio card built-in my motherboard. The Windows driver comes with a control panel that allows me to select which back panel jacks are used for what. So for example I can make both the blue jack and green jack for output and only the red one for mic-in. (Whereas by default, the blue jack is for line in, which I never need.) How can I do the same under Linux? If possible, please don't suggest something that involves PulseAudio or JACK; I'd like to do it the plain way, e.g. by editing ALSA configuration files, if possible. The way I understand it, my problem should have nothing to do with software servers redirecting streams, just instructing the driver to treat this jack as so and so because it's hardware supported. Thank you very much!

  • Choose an output audio device different from the default on WMP 11

    - by GetFree
    I like to play my music through a Hi-Fi audio equipment and everything else (like windows sounds, web videos and such) through my default PC speakers. On WIndows XP I had WMP 9 and I could do that with no problems since I can choose what audio device (which sound card) to use, and that selection is for WMP only, which can be different from Windows' default audio device. But now that I have Windows Vista and WMP 11 I cannot longer choose an audio device just for WMP, or at least I can't find a way to do it (the control in the options dialog is no longer there). Was this useful feature really removed from WMP 11? or there is some other way to do it?

  • removing contents of div using Jquery "empty" doesn't work

    - by Andrew
    I'm trying to remove contents of particular div which are basically list items and a heading by using jquery empty so that I could replace with new contents. What happens when I run the code is, the whole div element blinked and flash the replaced content and then the old one reappear. Can anyone tell me what am I doing wrong? Here's an excerpt of my code - <pre> $("#msg_tab").bind("click",function(){ $("#sidebar1").remove(); var html="<ul><li><h2>test</h2><ul><li><a href='#'>Compose New Message</a></li><li><a href='#'>Inbox</a></li><li><a href='#'>Outbox</a></li><li><a href='#'>Unread</a></li><li><a href='#'>Archive</a></li></ul></li></ul>"; $("#sidebar1").append(html); }); <div id="sidebar1" class="sidebar"> <ul> <li> <h2>Messages</h2> <ul> <li><a href="#">Compose New Message</a></li> <li><a href="#">Inbox</a></li> <li><a href="#">Outbox</a></li> <li><a href="#">Unread</a></li> <li><a href="#">Archive</a></li> </ul> </li> </ul> </div> Another question is, how do I write multiple line html code string in javascript so that java would recognize as a string value? Placing forward slash at the end is ok when the string is not a html code but, in html code, I can't figure out how to escape forward slash from ending tags.I've tried escaping it with backward slash but doesn't work. I would be appreciated if anyone could shed a light on this matter as well.

  • Jetty servlet respons to Ajax always empty

    - by chris
    Hi I try to run a java server on Jetty which should respond to an ajax call. Unfortunately the response seems to be empty when I call it with ajax. When I call http://localhost:8081/?id=something I get an answer. The Java Server: public class Answer extends AbstractHandler { public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { String id = request.getParameter("id"); response.setContentType("text/xml"); response.setHeader("Cache-Control", "no-cache"); response.setContentLength(19+id.length()); response.setStatus(HttpServletResponse.SC_OK); response.getWriter().write("<message>"+id+"</message>"); //response.setContentType("text/html;charset=utf-8"); response.flushBuffer(); baseRequest.setHandled(true); } public static void main(String[] args) throws Exception { Server server = new Server(8081); server.setHandler(new Answer()); server.start(); server.join(); } } The js and html: <html> <head> <script> var req; function validate() { var idField = document.getElementById("userid"); var url = "validate?id=" + encodeURIComponent(idField.value); if (typeof XMLHttpRequest != "undefined") { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); } req.open("GET", "http://localhost:8081?id=fd", true); req.onreadystatechange = callback; req.send(null); } function callback() { if (req.readyState == 4) { if (req.status == 200) { var message = req.responseXML.getElementsByTagName("message")[0]; document.getElementById("userid").innerHTML = "message.childNodes[0].nodeValue"; } } } </script> </head> <body onload="validate('foobar')"> <div id="userid">hannak</div> </body> </html> I'm actually don't know what I'm doing wrong here. Maybe someone has a good idea. greetings chris

  • String.Empty in strings, need some explanation if possible :)

    - by Pabuc
    Hello all, 2 days ago, there was a question related to string.LastIndexOf(String.Empty) returning the last index of string. So I thought that; a string can always contain string.empty between characters like: "testing" == "t" + String.Empty + "e" + String.Empty +"sting" + String.Empty; After this, I wanted to test if String.IndexOf(String.Empty) was returning 0 because since String.Empty can be between any char in a string, that would be what I expect it to return and I wasn't wrong. string testString = "testing"; int index = testString.LastIndexOf(string.Empty); // index is 6 index = testString.IndexOf(string.Empty); // index is 0 It actually returned 0. I started to think that if I could split a string with String.Empty, I would get at least 2 string and those would be String.Empty and rest of the string since String.IndexOf(String.Empty) returned 0 and String.LastIndexOf(String.Empty) returned length of the string.. Here is what I coded: string emptyString = string.Empty; char[] emptyStringCharArr = emptyString.ToCharArray(); string myDummyString = "abcdefg"; string[] result = myDummyString.Split(emptyStringCharArr); The problem here is, I can't obviously convert String.Empty to char[] and result in an empty string[]. I would really love to see the result of this operation and the reason behind this. So my questions are: Is there any way to split a string with String.Empty? If it is not possible but in an absolute world which it would be possible, would it return an array full of chars like [0] = "t" [1] = "e" [2] = "s" and so on or would it just return the complete string? Which would make more sense and why? Thank you for your time.

  • Using OUTPUT/INTO within instead of insert trigger invalidates 'inserted' table

    - by Dan
    I have a problem using a table with an instead of insert trigger. The table I created contains an identity column. I need to use an instead of insert trigger on this table. I also need to see the value of the newly inserted identity from within my trigger which requires the use of OUTPUT/INTO within the trigger. The problem is then that clients that perform INSERTs cannot see the inserted values. For example, I create a simple table: CREATE TABLE [MyTable]( [MyID] [int] IDENTITY(1,1) NOT NULL, [MyBit] [bit] NOT NULL, CONSTRAINT [PK_MyTable_MyID] PRIMARY KEY NONCLUSTERED ( [MyID] ASC )) Next I create a simple instead of trigger: create trigger [trMyTableInsert] on [MyTable] instead of insert as BEGIN DECLARE @InsertedRows table( MyID int, MyBit bit); INSERT INTO [MyTable] ([MyBit]) OUTPUT inserted.MyID, inserted.MyBit INTO @InsertedRows SELECT inserted.MyBit FROM inserted; -- LOGIC NOT SHOWN HERE THAT USES @InsertedRows END; Lastly, I attempt to perform an insert and retrieve the inserted values: DECLARE @tbl TABLE (myID INT) insert into MyTable (MyBit) OUTPUT inserted.MyID INTO @tbl VALUES (1) SELECT * from @tbl The issue is all I ever get back is zero. I can see the row was correctly inserted into the table. I also know that if I remove the OUTPUT/INTO from within the trigger this problem goes away. Any thoughts as to what I'm doing wrong? Or is how I want to do things not feasible? Thanks.
