  • WPF UserControl Style results in error message

    - by Didier
    Hi I'm new in WPF so I try to create a WPF UserControl. My problem is about the style of the user control I've Created. On a design time I got this error message Can only base on a Style with target type that is base type 'RichTextBox'. at System.Windows.Style.Seal() at

  • HELP: MS Virtual Disk Service to Access Volumes and Discs on Local Machine.

  • Read Song Title/Artist from a live audio stream with Silverlight 4?

    - by Brent Pabst
    I have a SL4 project that is successfully streaming a great sounding WMA audio stream from a remote location. All of the MediaElement actions are straight forward. What I want to do is read the attributes that are passed as text along with the Audio stream. For instance the encoder of the stream embeds the title of the stream, the title of the song playing and the name of the artist for the current song. How would I pick this out using Silverlight 4 and then display it in a Label to the user? It sure would be easier than writing a bunch of web services to do the same thing. Windows Media Player and WinAmp all get the information I am just not seeing it in the MediaElement object collection.

  • Can I use a MIME type declaration to get an HTML file to open in MS Word?

    - by Toph
    Bill James wrote: I was able to render an HTML page with the MIME type set to "application/msword", which caused the browser to spawn Word which imported the html just fine, allowing edits and saving just as if I'd output a real Word doc. That sounds great to me, but I haven't been able to get it to work in any browser (Chrome/FF/Safari/Opera/IE on Win7 running Word 2010 beta). I tried changing the MIME type in the HTTP headers of several pages via Tamper Data to application/msword, and I tried using the http-equiv meta tag <meta http-equiv="Content-type" content="application/msword"> on a local HTML file I tried opening from the browser, but neither appeared to have any effect. I don't really have a clue with regard to HTTP headers and MIME types generally, so - any tips? Many thanks!

  • Is Multicast broken for Android 2.0.1 (currently on the DROID) or am I missing something?

    - by Gubatron
    This code works perfectly in Ubuntu, in Windows and MacOSX, it also works fine with a Nexus-One currently running firmware 2.1.1. I start sending and listening multicast datagrams, and all the computers and the Nexus-One will see each other perfectly. Then I run the same code on a Droid (Firmware 2.0.1), and everybody will get the packets sent by the Droid, but the droid will listen only to it's own packets. This is the run() method of a thread that's constantly listening on a Multicast group for incoming packets sent to that group. I'm running my tests on a local network where I have multicast support enabled in the router. My goal is to have devices meet each other as they come on line by broadcasting packages to a multicast group. public void run() { byte[] buffer = new byte[65535]; DatagramPacket dp = new DatagramPacket(buffer, buffer.length); try{ MulticastSocket ms = new MulticastSocket(_port); ms.setNetworkInterface(_ni); //non loopback network interface passed ms.joinGroup(_ia); //the multicast address, currently 224.0.1.16 Log.v(TAG,"Joined Group " + _ia); while (true) { ms.receive(dp); String s = new String(dp.getData(),0,dp.getLength()); Log.v(TAG,"Received Package on "+ _ni.getName() +": " + s); Message m = new Message(); Bundle b = new Bundle(); b.putString("event", "Listener ("+_ni.getName()+"): \"" + s + "\""); m.setData(b); dispatchMessage(m); //send to ui thread } } catch (SocketException se) { System.err.println(se); } catch (IOException ie) { System.err.println(ie); } } Over here, is the code that sends the Multicast Datagram out of every valid network interface available (that's not the loopback interface). public void sendPing() { MulticastSocket ms = null; try { ms = new MulticastSocket(_port); ms.setTimeToLive(TTL_GLOBAL); List<NetworkInterface> interfaces = getMulticastNonLoopbackNetworkInterfaces(); for (NetworkInterface iface : interfaces) { //skip loopback if (iface.getName().equals("lo")) continue; ms.setNetworkInterface(iface); _buffer = ("FW-"+ _name +" PING ("+iface.getName()+":"+iface.getInetAddresses().nextElement()+")").getBytes(); DatagramPacket dp = new DatagramPacket(_buffer, _buffer.length,_ia,_port); ms.send(dp); Log.v(TAG,"Announcer: Sent packet - " + new String(_buffer) + " from " + iface.getDisplayName()); } } catch (IOException e) { e.printStackTrace(); } catch (Exception e2) { e2.printStackTrace(); } } Update (April 2nd 2010) I found a way to have the Droid's network interface to communicate using Multicast! _wifiMulticastLock = ((WifiManager) context.getSystemService(Context.WIFI_SERVICE)).createMulticastLock("multicastLockNameHere"); _wifiMulticastLock.acquire(); Then when you're done... if (_wifiMulticastLock != null && _wifiMulticastLock.isHeld()) _wifiMulticastLock.release(); After I did this, the Droid started sending and receiving UDP Datagrams on a Multicast group. gubatron

  • How can I export images from MS SQL Server to a file on disk?

    - by rball
    I have a User table that has all of their avatars saved in an image field. I'd like to just take that out of the database and store it as a regular file on disk. I looked around and saw some code for textcopy, but that doesn't seem to be on my machine for some reason. Here is the code I wrote up anyway. Anyone know a way to get this done? DECLARE @exec_str varchar (255) SELECT @exec_str = 'textcopy /S (local)\SQLEXPRESS' + --' /U ' + @login + --' /P ' + @password + ' /D thedatabase' + ' /T User'+ ' /C AvatarImage' + ' /F "d:\Avatars\' + User.Name + '.jpg"' + ' /O' FROM [User] WHERE UserID = 2 EXEC master..xp_cmdshell @exec_str

  • MS SQL Server 15MM rows, simple COUNT query. 15+ seconds?

    - by john
    We took over a website from another company after a client decided to switch. We have a table that grows by about 25k records a day, and is currently at 15MM records. The table looks something like: id (PK, int, not null) member_id (int, not null) another_id (int, not null) date (datetime, not null) SELECT COUNT(id) FROM tbl can take up to 15 seconds. A simple inner join on 'another_id' takes over 30 seconds. I can't imagine why this is taking so long. Any advice? SQL Server 2005 Express

  • Foreign key onto weak entity set in MS SQL Server 2008?

    - by Nic Waller
    I'm using Microsoft SQL Server 2008 Management Studio to create a relational schema by following an Entity-Relationship diagram. (included below; unrelated details removed) Until now, primary and foreign keys have been working as expected. But when I try to create a foreign key from the entity relationship takes onto the weak entity set section, I get an error. Section is identified by a composite primary key in the context of course, which has course_id as a primary key. Therefore, the primary key of section is a 4-way composite key. The entity relationship takes needs to refer to section, so it includes all 4 primary attributes from section in it's own primary key. When trying to establish a foreign key relationship from takes to section, Studio gives the following error: The columns in table 'section' do not match an existing primary key or UNIQUE constraint. Am I doing something wrong, or is this an unsupported configuration? I can provide more details or the SQL schema if necessary.

  • Debugging dynamic sql + dynamic tables in MS SQL Server 2008.

    - by Hamish Grubijan
    Hi, I have a messy stored procedure which uses dynamic sql. I can debug it in runtime by adding print @sql; where @sql; is the string containing the dynamic SQL, right before I call execute (@sql);. Now, the multi-page stored procedure also creates dynamic tables and uses them in a query. I want to print those tables to the console right before I do an execute, so that I know exactly what the query is trying to do. However, the SQL Server 08 does not like that. When I try: print #temp_table; and try to compile the S.P. I get this error: The name "#temp_table" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted. Please help.

  • Using pyodbc to insert rows into a MS Access MDB, how do I escape the paramaters?

    - by MDBGuy
    Hi, I'm using pyodbc to talk to a legacy Access 2000 .mdb file. I've got a cursor, and am trying to execute this: c.execute("INSERT INTO [Accounts] ([Name], [TypeID], [StatusID], [AccountCat], [id]) VALUES (?, ?, ?, ?, ?)", [u'test', 20, 10, 4, 2]) However, doing so results in pyodbc.Error: ('HYC00', '[HYC00] [Microsoft][ODBC Microsoft Access Driver]Optional feature not implemented (106) (SQLBindParameter)') I understand I can simply change the question marks to the literal values, but in my experience proper escaping of strings across databases is... not pretty. PHP and mysql team up to bring mysql_real_escape_string and friends, but I can't seem to find pyodbc's function for escaping values. If you could let me know what the recommended way of inserting this data (from python) is, that'd be very helpful. Alternatively, if you have a python function to escape the odbc strings, that would also be great. Thanks for the help.

  • How do I read live camera data on the iPhone (like Microsoft Tag Reader)?

    - by Bill
    While the user is still in UIImagePickerController, I'd like to be able to get a UIImage representation of the image in the camera, make some changes to the image, and then display the altered image instead of the image coming directly from the camera. How can I do this? I tried setting a timer and calling takePicture, but calling it seemed to have no effect. The documentation says: Calling this method while an image is being captured has no effect. You must wait until the associated delegate object receives an imagePickerController:didFinishPickingMediaWithInfo: message before you can capture another picture. So how can I do this? I know that it's possible, since apps like Tag Reader are able to detect when something specific rolls in front of the camera. Thanks!

  • Does MS PnP Unity Scan for Assemblies Like StructureMap?

    - by rasx
    In Using StructureMap 2.5 to scan all assemblies in a folder, we can see that StructureMap uses AssembliesFromPath() to explicitly look for types to resolve. What is the equivalent of this in Microsoft Unity? Because Unity is such a generic term, searching for documents about this online is not that easy. Update: Unity has something called an Assembly Matching Rule but its description does not communicate to me that it scans folders.

  • Best open source alternative for MS Visual Source Safe?

    - by afsharm
    We are leaving VSS for TFS or any other alternatives. I'm the one who persists to go for an open source alternative like SVN. Now I'm searching for a good open source Version Control regarding following aspects: We are in love with open source movement and cross-platform. Could it be possible to use it with Mono, SharpDevelop and Express editions of VS instead of Visual Studio itself? What about backup? Is it integrated with VS without serious problems? Any API or command prompt access? Please notice I've read following previous texts about it but still need more help: http://stackoverflow.com/questions/690766/vss-or-svn-for-a-net-project http://stackoverflow.com/questions/61959/tfs-vs-open-source-alternatives http://stackoverflow.com/questions/44588/how-to-convince-a-company-to-switch-their-source-control

  • Using RJS to replace innerHTML with a real live instance variable.

    - by Steve Cotner
    I can't for the life of me get RJS to replace an element's innerHTML with an instance variable's attribute, i.e. something like @thing.name I'll show all the code (simplified from the actual project, but still complete), and I hope the solution will be forehead-slap obvious to someone... In RoR, I've made a simple page displaying a random Chinese character. This is a Word object with attributes chinese and english. Clicking on a link titled "What is this?" reveals the english attribute using RJS. Currently, it also hides the "What is this?" link and reveals a "Try Another?" link that just reloads the page, effectively starting over with a new random character. This is fine, but there are other elements on the page that make their own database queries, so I would like to load a new random character by an AJAX call, leaving the rest of the page alone. This has turned out to be harder than I expected: I have no trouble replacing the html using link_remote_to and page.replace_html, but I can't get it to display anything that includes an instance variable. I have a Word resource and a Page resource, which has a home page, where all this fun takes place. In the PagesController, I've made a couple ways to get random words. Either one works fine... Here's the code: class PagesController < ApplicationController def home all_words = Word.find(:all) @random_word = all_words.rand @random_words = Word.find(:all, :limit => 100, :order => 'rand()') @random_first = @random_words[1] end end As an aside, the SQL call with :limit => 100 is just in case I think of some way to cycle through those random words. Right now it's not useful. Also, the 'rand()' is MySQL specific, as far as I know. In the home page view (it's HAML), I have this: #character_box = render(:partial => "character", :object => @random_word) if @random_word #whatisthis = link_to_remote "? what is this?", :url => { :controller => 'words', :action => 'reveal_character' }, :html => { :title => "Click for the translation." } #tryanother.{:style => "display:none"} = link_to "try another?", root_path Note that the #'s in this case represent divs (with the given ids), not comments, because this is HAML. The "character" partial looks like this (it's erb, for no real reason): <div id="character"> <%= "#{@random_word.chinese}" } %> </div> <div id="revealed" style="display:none"> <ul> <li><span id="english"><%= "#{@random_word.english_name}" %></span></li> </ul> </div> The reveal_character.rjs file looks like this: page[:revealed].visual_effect :slide_down, :duration => '.2' page[:english].visual_effect :highlight, :startcolor => "#ffff00", :endcolor => "#ffffff", :duration => '2.5' page.delay(0.8) do page[:whatisthis].visual_effect :fade, :duration => '.3' page[:tryanother].visual_effect :appear end That all works perfectly fine. But if I try to turn link_to "try another?" into link_to_remote, and point it to an RJS template that replaces the "character" element with something new, it only works when I replace the innerHTML with static text. If I try to pass an instance variable in there, it never works. For instance, let's say I've defined a second random word under Pages#home... I'll add @random_second = @random_words[2] there. Then, in the home page view, I'll replace the "try another?" link (previously pointing to the root_path), with this: = link_to_remote "try another?", :url => { :controller => 'words', :action => 'second_character' }, :html => { :title => "Click for a new character." } I'll make that new RJS template, at app/views/words/second_character.rjs, and a simple test like this shows that it's working: page.replace_html("character", "hi") But if I change it to this: page.replace_html("character", "#{@random_second.english}") I get an error saying I fed it a nil object: ActionView::TemplateError (undefined method `english_name' for nil:NilClass) on line #1 of app/views/words/second_character.rjs: 1: page.replace_html("character", "#{@random_second.english}") Of course, actually instantiating @random_second, @random_third and so on ad infinitum would be ridiculous in a real app (I would eventually figure out some better way to keep grabbing a new random record without reloading the page), but the point is that I don't know how to get any instance variable to work here. This is not even approaching my ideal solution of rendering a partial that includes the object I specify, like this: page.replace_html 'character', :partial => 'new_character', :object => @random_second As I can't get an instance variable to work directly, I obviously cannot get it to work via a partial. I have tried various things like: :object => @random_second or :locals => { :random_second => @random_second } I've tried adding these all over the place -- in the link_to_remote options most obviously -- and studying what gets passed in the parameters, but to no avail. It's at this point that I realize I don't know what I'm doing. This is my first question here. I erred on the side of providing all necessary code, rather than being brief. Any help would be greatly appreciated.
