  • .NET: XDocument missing XDeclaration?

    - by JamesBrownIsDead
    When I write out this to the console, the output is missing the XDeclaration content. What gives? var map = new XDocument( new XDeclaration("1.0", "UTF-8", null), new XElement(SiteMap.Namespace + "urlset") ); Console.Write(map.ToString()); How do I get the XML for map including the <?xml...> declaration?

  • Sanity Check: change event not firing first time using keyboard

    - by macca1
    I've done a good amount of research on this and found a bunch of reported problems and solutions but the general consensus seems that all change problems in IE6 were fixed in jQuery 1.4.2. I'm having an issue where a change event is not firing in jQuery 1.4.2, but it did fire successfully in jQuery 1.3.2. This is in IE6. I'm about to submit a bug for this, but for my sanity I wanted to post it here first to see if there's something dumb I'm missing. I don't understand why this is working this way... <HTML> <HEAD> <TITLE>jQuery 1.4.2 Problem </TITLE> <script src="jquery-1.4.2.min.js" type="text/javascript"></script> <script> $(document).ready( function() { $("#firstBox").change(function() { alert("CHANGE"); }); // ONLOAD of document autofocus into the first element... $("form").find(":input:visible:first").focus() }); </script> </HEAD> <BODY> <form> <select id="firstBox"> <option value="" selected="selected">--</option> <option value="1">One</option> <option value="2">Two</option> </select> <br><br> <input size="10" id="secondBox"> </form> </BODY> </HTML> Simple enough, right? Onload of the page, give the first element focus. Onchange of the first element, alert. If you use the mouse, it works as expected. The page loads, the focus is in the drop down, you change the option, you get the alert. The problem is if you use the keyboard. The page loads, the focus is in the drop down, you press the down arrow. The option changes. Tab off the field, no alert. Weird. To make it even weirder, if you tab back into the field and change it again (all using the keyboard), the change event DOES fire after tab out this time. Any ideas?

  • Multi-thread conversation in django (like Reddit)

    - by dotty
    Hay, i have an app which essentially a conversation system (much like reddits) Where a post can have multiple replies, and a reply and have multiplies, and a reply to a reply can have multiple replies (etc) I've made the model like this class Discussion(models.Model): message = models.TextField() replies = models.ManyToManyField('self') and the view discussions = Discussions.objects.all() and the template looks like this {% for discussion in discussions %} {{ discussion.message }} {% endfor %} How would i go about making a system where i can output all replies like this discussion reply reply reply reply reply reply Which would go down as far as it needs to to ensure all replies are listed. Thanks

  • Flash AS3 button eventlistener array bug

    - by Tyler Pepper
    Hi there, this is my first time posting a question here. I have an array of 12 buttons on a timeline that when first visiting that part of the timeline, get a CLICK eventlistener added to them using a for loop. All of them work perfectly at that point. When you click one it plays a frame label inside the specific movieClip and reveals a bio on the corresponding person with a close button and removes the CLICK eventlisteners for each button, again using a for loop. The close button plays a closing animation, and then the timeline goes back to the first frame (the one with the 12 buttons on it) and the CLICK eventlisteners are re-added, but now only the first 9 buttons of the array work. There are no output errors and the code to re-add the eventlisteners is exactly the same as the first time that works. I am completely at a loss and am wondering if anyone else has run into this problem. All of my buttons are named correctly, there are absolutely no output errors (I've used the debug module) and I made sure the array with the buttons in it is outputting all 12 at the moment the close button is clicked to add the eventlisteners back. for (var q = 0; q < ackBoDBtnArray.length; q++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[q]].addEventListener(MouseEvent.CLICK, showBio); } private function showBio(eo:MouseEvent):void { trace("show the bio"); bodVar = ackBoDBtnArray.getIndex(eo.target.name); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDPgArray[bodVar]); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.addEventListener(MouseEvent.CLICK, hideBio); for (var r = 0; r < ackBoDBtnArray.length; r++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].mouseEnabled = false; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].removeEventListener(MouseEvent.CLICK, showBio); } } private function hideBio(eo:MouseEvent):void { trace("hide it!"); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.removeEventListener(MouseEvent.CLICK, hideBio); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDClosePgArray[bodVar]); for (var s = 0; s < ackBoDBtnArray.length; s++){ trace(ackBoDBtnArray[s]); contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].mouseEnabled = true; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].addEventListener(MouseEvent.CLICK, showBio); } Thanks in advance for any help and insight you can provide...I have a slight feeling that its something that may be obvious to another set of eyes...haha.

  • XNA/C# Game Settings (Menu?)

    - by PCAddict
    It's my first time trying to make anything really interesting in C# and I was trying to make a simple form or game screen where the user could define a custom resolution/screen ratio etc. or to automatically detect the max screen size/ratio and output? its my first game, so I was wondering if it was possible or if there would be any major issues with such, rather than just setting it to 1366x768 (the resolution of all of my computers). Thanks in advance for any assistance.

  • rake db:migrate not executing new migrations

    - by Matt H
    Hi guys. I'm trying to add some columns to an existing table, so I generated a migration that did so. When I run db:migrate the new migration isn't run and the table isn't updated. I've had this problem many times before, and it's getting bloody annoying. Output from rake db:migrate $ rake db:migrate --trace (in /Users/one/app) ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate ** Invoke db:schema:dump (first_time) ** Invoke environment ** Execute db:schema:dump

  • How can I track an asp.net pages size without tracing?

    - by Middletone
    I want to be able to track the amount of data that is being transfered from my web site to each user that accesses the site. I can do this for file downloads and such but what about the pure html content itself. How can I track the output size of a page (or the data that's trasnfered via an AJAX call) to the client and log it against a particular users session? Also how would this differ when GZip is used in IIS 6.0?

  • Example compilers

    - by saf
    I'm searching for the source code of a compiler capable of creating Win32 programs from an input program in a programming language (It doesn't matter which, maybe the simpler the better) Yet I can't find anything right for me and huge compilers like GCC make me extremely confused as they have so many features that I don't know where to start. Is there an OpenSource Win32 micro-compiler for some programming language out there I could take a look at?

    - by Elliott
    Hi, I have a page in which users can make "posts" its similar to facebook, I am trying to figure out how I can get it to run the php loop say every 10mins, in order for the person to see new posts. Everytime a post is made it is added into the db and then the page is refreshed, I want to do it more "facebook like". Using jquery slide down etc. Below is what I have up2 now. function postdata() { $.ajax({ type: "POST", dataType: "text", url: "makepost.php", data: "post_text=" + $("#post_text").val(), cache: false, success: function(reply_text) { if (reply_text.indexOf("Successful") >= 0) { alert("Post Made"); window.location = "index.php" } else { alert(reply_text); } } }); } </script> <div id="content"> <?php if (loggedin()) { $ID = getID(); $query = "SELECT * FROM `posts`"; $result=mysql_query($query); $count=mysql_num_rows($result); $users = "SELECT `userID` FROM `users`"; $resultID=mysql_query($users); while ($row = mysql_fetch_array($result)) { echo '<div class="posts">'; echo $row['2']."<br /><br />"; echo '<div class="posts_bottom">'; echo '<p class="name">'; echo showuser($row['1'])."</p>"; echo '<p class="rate">'; echo '<input type="submit" value="+1"/></p>'; echo '<p class="points">'; echo showpoints($row['1'])."</p>"; echo "</div>"; echo '</div>'; } echo '<div id="makepost"> <br /><textarea rows="3" cols="25" id="post_text" ></textarea><br /> <input type="submit" id="post_bttn" value="Post" onclick="postdata(); return false;"> </div>'; As they are put into a new div everytime I don't know what to refresh? Such as if it was one div I could jus refresh that, but these are being created and I don't know how many would need to be loaded. Any adivce? Thanks alot :D

  • Perl: Edit hyperlinks in nested tags that aren't on separate lines

    - by user305801
    I have an interesting problem. I wrote the following perl script to recursively loop through a directory and in all html files for img/script/a tags do the following: Convert the entire url to lowercase Replace spaces and %20 with underscores The script works great except when an image tag in wrapped with an anchor tag. Is there a way to modify the current script to also be able to manipulate the links for nested tags that are not on separate lines? Basically if I have <a href="..."><img src="..."></a> the script will only change the link in the anchor tag but skip the img tag. #!/usr/bin/perl use File::Find; $input="/var/www/tecnew/"; sub process { if (-T and m/.+\.(htm|html)/i) { #print "htm/html: $_\n"; open(FILE,"+<$_") or die "couldn't open file $!\n"; $out = ''; while(<FILE>) { $cur_line = $_; if($cur_line =~ m/<a.*>/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* href=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } if($cur_line =~ m/(<img.*>|<script.*>)/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* src=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } $out .= $cur_line; } seek(FILE, 0, 0) or die "can't seek to start of file: $!"; print FILE $out or die "can't print to file: $1"; truncate(FILE, tell(FILE)) or die "can't truncate file: $!"; close(FILE) or die "can't close file: $!"; } } find(\&process, $input); sub html_clean { my($input_string) = @_; $input_string = lc($input_string); $input_string =~ s/%20|\s/_/g; return $input_string; }

  • How do I set libavcodec to use 4:2:2 chroma when encoding MPEG-2 4:2:2 profile?

    - by Mike Pollitt
    I have a project using libavcodec (ffmpeg). I'm using it to encode MPEG-2 video at 4:2:2 Profile, Main Level. I have the pixel format PIX_FMT_YUV422P selected in the AVCodecContext, however the video output I'm getting has all the colours wrong, and looks to me like the encoder is incorrectly reading the buffers as though it thinks it is 4:2:0 chroma rather than 4:2:2. Here's my codec setup: // // AVFormatContext* _avFormatContext previously defined as mpeg2video // // // Set up the video stream for output // AVVideoStream* _avVideoStream = av_new_stream(_avFormatContext, 0); if (!_avVideoStream) { err = ccErrWFFFmpegUnableToAllocateStream; goto bail; } _avCodecContext = _avVideoStream->codec; _avCodecContext->codec_id = CODEC_ID_MPEG2VIDEO; _avCodecContext->codec_type = CODEC_TYPE_VIDEO; // // Set up required parameters // _avCodecContext->rc_max_rate = _avCodecContext->rc_min_rate = _avCodecContext->bit_rate = src->_avCodecContext->bit_rate; _avCodecContext->flags = CODEC_FLAG_INTERLACED_DCT; _avCodecContext->flags2 = CODEC_FLAG2_INTRA_VLC | CODEC_FLAG2_NON_LINEAR_QUANT; _avCodecContext->qmin = 1; _avCodecContext->qmax = 1; _avCodecContext->rc_buffer_size = _avCodecContext->rc_initial_buffer_occupancy = 2000000; _avCodecContext->rc_buffer_aggressivity = 0.25; _avCodecContext->profile = 0; _avCodecContext->level = 5; _avCodecContext->width = f->GetWidth(); // f is a private Frame class with width, height properties etc. _avCodecContext->height = f->GetHeight(); _avCodecContext->time_base.den = 25; _avCodecContext->time_base.num = 1; _avCodecContext->gop_size = 12; _avCodecContext->max_b_frames = 2; _avCodecContext->pix_fmt = PIX_FMT_YUV422P; if (_avFormatContext->oformat->flags & AVFMT_GLOBALHEADER) { _avCodecContext->flags |= CODEC_FLAG_GLOBAL_HEADER; } if (av_set_parameters(_avFormatContext, NULL) < 0) { err = ccErrWFFFmpegUnableToSetParameters; goto bail; } // // Set up video codec for encoding // AVCodec* _avCodec = avcodec_find_encoder(_avCodecContext->codec_id); if (!_avCodec) { err = ccErrWFFFmpegUnableToFindCodecForOutput; goto bail; } if (avcodec_open(_avCodecContext, _avCodec) < 0) { err = ccErrWFFFmpegUnableToOpenCodecForOutput; goto bail; } A screengrab of the resulting video frame can be seen at http://ftp.limeboy.com/images/screen_grab.png (the input was standard colour bars). I've checked by outputting debug frames to TGA format at various points in the process, and I can confirm that it is all fine and dandy up until the point that libavcodec encodes the frame. Any assistance most appreciated! Cheers, Mike.

  • Concatenation of files using ffmpeg does not work as I expected. Why?

I do not understand why ffmpeg is not concatenating. Any help is dramatically appreciated,

  • HelloWebView Sample: now using SDK 3 and getting killed

    - by Tim
    Hey Folks, Well I was trying to get the HelloWebview example working with SDK 7 with no success (see HelloWebView Sample: java.lang.SecurityException: Permission Denial thread), so I decided just out of curiosity to back off to SDK3 to see if I could learn anything. I have been able to get all the "Layout" samples to work and decided to try something a little harder. Unfortunately, I still cannot get the simple HelloWebView app to run. I no longer get a Permission Denial but now the app is getting killed. Killed usually implies that there are not enough resources (memory etc.) for an application to run.... Any thoughts? Are there any other log files I can look at either on my computer or on the emulator? The main.xml, manifest, and console output are below. Let me know if you need more information.
