• Grouped UITableView Footer Sometimes Hidden On Quick Scroll

  - by jdandrea

  OK, this one is a puzzler. There is one similar post but it's not similar enough to count, so I'm posting this one. :) I've got a grouped UITableView with a header and footer. The footer includes two UIButton views, side-by-side. Nothing major. Now … there is a toggle button in a UIToolbar at the bottom for more/less info in this table view. So I build my index paths to delete/insert with fade row animation, all the usual ingredients, sandwiched between beginUpdates and endUpdates calls on the UITableView … and this works fine! In also happens that my footer can sometimes be pushed off past the bottom of the display. Here's where it gets weird. If I drag my finger up the display, scrolling the view upward, I should see that footer eventually, right? Well … most of the time I do. BUT, if I flick my finger up, for a faster scroll, the footer is missing. Even if you try to tap in that area - no response. However, if I scroll back down again, just to hide that footer (or rather hide the area where the footer would normally be), and then scroll back up, it's there once again! This only happens when inserting rows. If I delete rows, the footer stays put … unless of course it was already hidden and I didn't perform the aforementioned incantation to get it back. :) I am trying to trace through this, but to no avail. I suppose tracing through scroll operations is a bit of a crazy proposition! Perhaps some creative logging … suggestions, anyone? Or is this a known issue in 3.1 where row insert/deletes are concerned? (I don't recall seeing it until 3.1.)

• MySQL can't access root account or reset with mysqladmin

  - by glumptious

  So if I type mysql -u root I'm supposedly logged in, however upon trying to create or access a database I get this lovely error: ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'test1'. I haven't the foggiest idea why after logging in as root it's trying access DB's as ''@'localhost' and it's driving me a bit crazy right now. Possibly related, when I try to set the root password I get the error mysqladmin: Can't turn off logging; error: 'Access denied; you need (at least one of) the SUPER privilege(s) for this operation'. I've tried removing mysql-server via running apt-get purge mysql-server and then reinstalling with no luck. This is running Ubuntu Server 12.10 64-bit and mysql is indeed running. --Edit-- I wonder if perhaps there is no root user. So I try to start MySQL with --skip-grant-tables and the create the root user but then I'm given this: ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement. Fun fun fun fun fun.

• ASP.NET MVC on Cassini: How can I force the "content" directory to return 304s instead of 200s?

  - by Portman

  Scenario: I have an ASP.NET MVC application developed in Visual Studio 2008. There is a root folder named "Content" that stores images and stylesheets. When I run locally (using Cassini) and browse my application, every resource from the "Content" directory is always downloaded. Using Firebug, I can verify that the web server returns an HTTP 200 ("ok"). Desired: I would like for Cassini to return HTTP 304 ("not modified") instead of 200. This is the behavior when running the site under IIS7. Reasoning: The site I am working on has a large number of static resources (often as many as 40 per page). Browsing the site is very fast on IIS7, because these resources are (correctly) cached by the browser. However, browsing the site on my local machine is painfully slow. Pages that render in under 1 second on IIS7 take over 30 seconds to render on Cassini. It's actually faster for me to upload the entire website every few minutes and test from there. (Yes, I recognize that this is perverse and crazy.) So: how can I instruct/trick Cassini into treating the "Content" directory like IIS7 does?

• SD card initialization SPI

  - by Openavr

  Hi People I saw a lot of infos about MMC/SD cards and I tried to make a lib to read this.. (modifying the Procyon Avrlib) But I have some problems here. I Don´t change the original code and tried here. My problem is about the init of SD card. I have 2 here, a 256mb and another 1GB. I send the init commands like this order: CMD0, CMD55, ACMD41, CMD1 But SD 256mb returns me only 0x01 response for each command.. the CMD1 i send a lot of times, SD 256mb always returs only 0x01.. never 0x00. The SD 1GB is more crazy... CMD0 returns with 0x01 ..nice but the CMD55 response with 0x05... another times responde with 0xC1... and another ones response 0xF0 with a 0x5F in the next interation... Around internet have infos and examples, but a bit of confused. Here in my project, I must use 1GB card and I´m trying with a MicroSD with a SD Adapter (I think that this is not the problem). Please any help are apreciate! Regards PS - my problem like the problem from this guy http://stackoverflow.com/questions/2365897/initializing-sd-card-in-spi-issues but his solution don´t solved my problem.. The SD1GB returns only 0x01 ever... :cry:

• How can I stop SQL Server Management Studio replacing 'SELECT *' with the column list ?

  - by Ben McIntyre

  SQL Server Mgmt Studio is driving me crazy. If I create a view and SELECT '*' from a table, it's all OK and I can save the view. Looking at the SQL for the view (eg.by scripting a CREATE) reveals that the 'SELECT *' really is saved to the view's SQL. But as soon as I reopen the view using the GUI (right click modify), SELECT * is replaced with a column list of all the columns in the table. How can I stop Management Studio from doing this ? I want my 'SELECT *' to remain just that. Perhaps it's just the difficulty of googling 'SELECT *' that prevented me from finding anything remotely relevant to this (i did put it in double quotes). Please, I am highly experienced in Transact-SQL, so please DON'T give me a lecture on why I shouldn't be using SELECT *. I know all the pros and cons and I do use it at times. It's a language feature, and like all language features can be used for good or evil (I emphatically do NOT agree that it is never appropriate to use it). Edit: I'm giving Marc the answer, since it seems it is not possible to turn this behaviour off. Problem is considered closed. I note that Enterprise Manager did no similar thing. The workaround is to either edit SQL as text, or go to a product other than Managment Studio. Or constantly edit out the column list and replace the * every time you edit a view. Sigh.

• iPhone SDK: How do you download video files to the Document Directory and then play them?

  - by Jessica

  I've been fooling around with code for ages on this one, I would be very grateful if someone could provide a code sample that downloaded this file from a server http://www.archive.org/download/june_high/june_high_512kb.mp4, (By the way it's not actually this file, it's just a perfect example for anyone trying to help me) and then play it from the documents directory. I know it seems lazy of me to ask this but I have tried so many different variations of NSURLConnection that it's driving me crazy. Also, if I did manage to get the video file downloaded would I be correct in assuming this code would then successfully play it: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"june_high_512kb.mp4"]; NSURL *movieURL = [NSURL fileURLWithPath:path]; self.theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; [_theMovie play]; If the above code would work in playing a video file from the document directory, then I guess the only thing I would need to know is, how to download a video file from a server. Which is what seems to be my major problem. Any help is greatly appreciated.

• jQuery .attr() crashing Internet Explorer

  - by Sunyatasattva

  Hello everyone, This is my first time posting a question here, as I usually try to find solutions myself. This one, though, being an IE issue, just drives me crazy. I use jQuery cycle plug-in on a website I made and, to populate a caption div, I use a little function that is called after the image is loaded, which uses the "alt" attribute of the image. This seems to exasperate Internet Explorer, which, doesn't have the time to fulfill this apparently so-complicated task, and, as the slideshow cycles, it enters in an infinite loop and eventually crashes – the newer the version, the worse the crash: the older IEs just display an error message saying “The webpage cannot be displayed”, while the newer (7 and 8) completely crash the system. I have no idea on how to solve or work around this. Here is the problematic code. function changeCaption() { var caption = $("img", this).attr("alt"); $('#caption').fadeIn("slow").html(caption); } Thanks in advance for any pointer: I am amazed as how something so simple and globally recognized (didn't encounter any other browser who had problem with this), can cause a problem so big. I also read somewhere that being able to crash a browser remotely is a serious issue :) Lucio

• CSS does not load when updated in an ASP.NET MVC 2 website

  - by dannie.f

  I have a weird problem. Whenever the website designer updates the css file for the website I am working on. I overwrite the old css file with the new version and copy any new images. The problem is that whenever I do this the images in the website header no longer loads along with some other styles that depend on css loading some images. I have tried everything, clearing the browser cache, deleting asp.net temporary files, restarting the browser, changing browsers and pressing Ctrl + F5. Still the images don't load. What usually happens also is that the problem would eventually correct itself and I wouldn't know why. This driving me crazy. Does anyone else have the problem and know how to fix it? If this helps, the header is located in a partial view and the master page loads the css file using Url.Content. The images are css sprites. This issue persists no matter which browser I try, Chrome, Firefox or IE. I am using Visual Studio 2008 SP1 on Windows 7 Ultimate. Other team members have experienced this issue.

• Join + IEqualityComparer<T> and HashCode

  - by Jesus Rodriguez

  Im writing my own LINQ reference but Im getting troubles with some of the more complicated operators implementations. There is a Join implementation that takes a IEqualityComparer Im getting just crazy. Im trying to understand it first before I write (obviously) Image this two lists: List<string> initials = new List<string> {"A", "B", "C", "D", "E"}; List<string> words = new List<string> {"Ant", "Crawl", "Pig", "Boat", "Elephant", "Arc"}; Nothing weird here. I want to join both lists by the Initial, something like: Initial=A Word=Ant Initial=A Word=Arc Initial=B Word=Boat ... I need a comparator, I wrote this: public class InitialComparator : IEqualityComparer<string> { public bool Equals(string x, string y) { return x.StartsWith(y); } public int GetHashCode(string obj) { return obj[0].GetHashCode(); } } The Join itself: var blah = initials.Join(words, initial => initial, word => word, (initial, word) => new {Initial = initial, Word = word}, new InitialComparator()); It's the first time Im using HashCodes, after a good session of debugging I see that every word go to the comparator and look at its HashCode, if another word has the same HashCode it calls equals. Since I want to compare just the initial I though that I just need the first letter Hash (Am I wrong?) The thing is that this is not working correctly. Its says that "Ant" and "Arc" are equals, Ok, its comparing every word in the same list or not, But it adds only the last word it finds, in this case Arc, ignoring Ant and Ant is equals to "A" too... If I put "Ant" and "Ant" it add both. In short, What is the way of doing something like that? I know that Im doing something wrong. Thank you.

• How to loop video using NetStream in Data Generation Mode

  - by WesleyJohnson

  I'm using a NetStream in Data Generation Mode to play an embeded FLV using appendBytes. When the stream is finished playing, I'd like to loop the FLV file. I'm not sure how to achieve this. Here is what I have so far (this isn't a complete example): public function createBorderAnimation():void { // Load the skin image borderAnimation = Assets.BorderAnimation; // Convert the animation to a byte array borderAnimationBytes = new borderAnimation(); // Initialize the net connection border_nc = new NetConnection(); border_nc.connect( null ); // Initialize the net stream border_ns = new NetStream( border_nc ); border_ns.client = { onMetaData:function( obj:Object ):void{ trace(obj); } } border_ns.addEventListener( NetStatusEvent.NET_STATUS, border_netStatusHandler ); border_ns.play( null ); border_ns.appendBytes( borderAnimationBytes ); // Initialize the animation border_vd = new Video( 1024, 768 ); border_vd.attachNetStream( border_ns ); // Add the animation to the stage ui = new UIComponent(); ui.addChild( DisplayObject( border_vd ) ); grpBackground.addElement( ui ); } protected function border_netStatusHandler( event:NetStatusEvent ):void { if( event.info.code == "NetStream.Buffer.Flush" || event.info.code == "NetStream.Buffer.Empty" ) { border_ns.appendBytesAction( NetStreamAppendBytesAction.RESET_BEGIN ); border_ns.appendBytes( borderAnimationBytes ); border_ns.appendBytesAction( NetStreamAppendBytesAction.END_SEQUENCE ); } } This will loop the animation, but it starts chewing up memory like crazy. I've tried using NetStream.seek(0) and NetStream.appendBytesAction( NetStreamAppendBytesAction.RESET_SEEK ), but then I'm not sure what to do next. If you just try to call appendBytes again after that, it doesn't work, presumably because I'm appending the full byte array which has the FLV header and stuff? I'm not very familiar with how that all works. Any help is greatly appreciated.

• Can you help with this assembly language code?

  - by Mugen

  Hi, I've been looking through a piece of code of a pc game that I'm trying to "improve". (ok so maybe I suck at the game but I still want to play it). Could you please look into the following code: fld dword ptr[ebp+00007B1C] fsub dword ptr[esp+64] fst dword ptr[ebp+00007B1C] call 004A2E48 This code is called every second for the level countdown timer. I need to stay on a particular level for a few minutes. If I can modify the above code so that the value pushed into the address [ebp+00007B1C] is 0 then the game level will always time out and it will save me playing those crazy "survival" minigames. I'll explain what I understand from this code. Dont worry, you dont have to go deep into this. In the first line we get the timer value. For example if 97 seconds are remaining then it is here that this value is loaded. In the second line a value (1 second) is subtracted from 97. In the third line 96 is again moved to memory. And finally we have the function call that will do other processing based on the time remaining. Now all I need to do is patch this piece of code somehow so that the value that is pushed is 0 (in the third step). Can you please help me out with this?

• Why does this Object wonk out & get deleted ?

  - by brainydexter

  Stepping through the debugger, the BBox object is okay at the entry of the function, but as soon as it enters the function, the vfptr object points to 0xccccc. I don't get it. What is causing this ? Why is there a virtual table reference in there when the object is not derived from other class. (Though, it resides in GameObject from which my Player class inherits and I retrieve the BBox from within player. But, why does the BBox have the reference ? Shouldn't it be player who should be maintained in that reference ?) For 1; some code for reference: A. I retrieve the bounding box from player. This returns a bounding box as expected. I then send its address to GetGridCells. const BoundingBox& l_Bbox = l_pPlayer-GetBoundingBox(); boost::unordered_set < Cell*, CellPHash & l_GridCells = GetGridCells ( &l_Bbox ); B. This is where a_pBoundingBox goes crazy and gets that garbage value. boost::unordered_set< Cell*, CellPHash CollisionMgr::GetGridCells(const BoundingBox *a_pBoundingBox) { I think the following code is also pertinent, so I'm sticking this in here anyways: const BoundingBox& Player::GetBoundingBox(void) { return BoundingBox( &GetBoundingSphere() ); } const BoundingSphere& Player::GetBoundingSphere(void) { BoundingSphere& l_BSphere = m_pGeomMesh-m_BoundingSphere; l_BSphere.m_Center = GetPosition(); return l_BSphere; } // BoundingBox Constructor BoundingBox(const BoundingSphere* a_pBoundingSphere); Can anyone please give me some idea as to why this is happening? Also, if you want me to post more code, please do let me know. Thanks!

• Going from small to medium sized websites.

  - by Landitus

  I've been coding websites for a couple of years now, mostly in php and xhtml. I come from the design world, but I'm proud of doing standart compliant websites and great interfaces. Also used Wordpress and loved it. Most of the time there were really simple commercial websites, with no database included, where everything is done from scratch. Every page is parsed through an index?page=xxx and But I have a few prospects that are larger websites (let's call them 'medium sized websites') where I feel I'm lacking the following: How to dispach or render the pages (MVC controller instead of index?page=???) Proper page hierarchy and easy breadcrumbs implementation Auto generation of navigation menu, or an easy way to maintain them? Clean URLs Form validation Easy database support I really don't know if I should be looking into php scripts, and refine my skills or get into a CMS (like drupal) or a PHP framework. I found Wordpress very assuring and didn't feel trapped into crazy conventions, but I feel is not the right tool for this. I hate the CMS Page with the big textbox as I am used to code every page by hand my pages are not a title and a textbox. Got the feeling? My php skills are sort of medium/low still, but I would like to hear some thoughts of what I should learn to take the next step!

• jQuery carousel in a div with display:none

  - by Fred Kafka

  I have to use on my site a jQuery responsive carousel with 4 displayed items that slide one at a time, etc etc. The point is: this carousel is placed in a div with display:none and it appears clicking on a button with a slideToggle script (jQuery). Well, when the div appears the carousel is not displayed. Nothing! Notice that if I remove the display:none the carousel shows perfectly. I've tried a bunch of carousel plugin (bxslider, caroufredsel, elastislide, flexslider) and this issue happens for all of them. And then... I'm going crazy!! Excuse meSorry friends, here is the code: HTML (here is the case of FlexSlider but the code is similar for the other plugins) <div id="hiddenDiv"> <div id="hiddenDivInner"> <div class="flexslider"> <ul class="slides"> <li>...</li> <li>...</li> <li>...</li> </ul> </div> </div> </div> CSS #hiddenDiv{ display:none; padding-bottom:10px; background: url("../img/xxx.gif") repeat left bottom #FFFFFF; } SCRIPT (copy-paste from the site. This script is between $(document).ready together with other scripts. Alredy tried to remove the load function) $(window).load(function() { $('.flexslider').flexslider({ animation: "slide", animationLoop: false, itemWidth: 300, itemMargin: 5, minItems: 1, maxItems: 4 }); }); $("#trigger").click(function () { $("#hiddenDiv").slideToggle(400, "easeInOutExpo"); }); I remind you that with this code and no display:none every carousels work, also if I slide up and then down the div using the slideToggle button (#trigger).

• Delphi access violation assigning local variable

  - by Justin

  This seems like the simplest thing in the world and I'm ready to pull my hair out over it. I have a unit that looks like this ; Unit myUnit; // ... //normal declarations //... Public //bunch of procedures including Procedure myProcedure; const //bunch of constants var //bunch of vars including myCounter:integer; Implementation Uses //(all my uses) // All of my procedures including Procedure myProcedure; try // load items from file to TListBox - this all works except on EReadError do begin // handle exception end; end; //try myCounter:=0; // <-- ACCESS VIOLATION HERE while myCounter //...etc It's a simple assignment of a variable and I have no idea why it is doing this. I've tried declaring the variable local to the unit, to the procedure, globally - no matter where I try to do it I can't assign a value of zero to an integer, declared anywhere, within this procedure without it throwing an access violation. I'm totally stumped. I'm calling the procedure from inside a button OnClick handler from within the same unit, but no matter where I call it from it throws the exception. The crazy thing is that I do the exact same thing in a dozen other places in units all over the program without problems. Why here? I'm at a total loss.

• Office 2003 interop problems, interface, method not found.

  - by Snake

  This problem is making me crazy. Actually I have multiple problems. First one: Why on earth are is there a _Worksheet and a Worksheetinterface in the Excel interop. They both look the same, except for some attributes on the methods. It's confusing! Second of all: my job today is making a VB.NET file more strict, by settings Option Strict On and Option Explicit On While it works for most files, I'm bumping into a problem. Here's a little code piece: Private _pivotTable As Excel.PivotTable With _pivotTable pvf = .AddDataField(pvc) End With PivotTable.AddDataField is defined on the MSDN page: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.pivottable.adddatafield(office.11).aspx When I check my local Interop dll w/ Reflector that method is NOT there. When I run the application, and step through it, the method just works. When I try to step INTO the method, I get an LateBound Exception. WTF? So the question is: why are the interfaces defined more than once (twice sometimes?). 2nd question. AddDataField trouble

• Django: Serving Media Behind Custom URL

  - by TheLizardKing

  So I of course know that serving static files through Django will send you straight to hell but I am confused on how to use a custom url to mask the true location of the file using Django. http://stackoverflow.com/questions/2681338/django-serving-a-download-in-a-generic-view but the answer I accepted seems to be the "wrong" way of doing things. urls.py: url(r'^song/(?P<song_id>\d+)/download/$', song_download, name='song_download'), views.py: def song_download(request, song_id): song = Song.objects.get(id=song_id) fsock = open(os.path.join(song.path, song.filename)) response = HttpResponse(fsock, mimetype='audio/mpeg') response['Content-Disposition'] = "attachment; filename=%s - %s.mp3" % (song.artist, song.title) return response This solution works perfectly but not perfectly enough it turns out. How can I avoid having a direct link to the mp3 while still serving through nginx/apache? EDIT 1 - ADDITIONAL INFO Currently I can get my files by using an address such as: http://www.example.com/music/song/1692/download/ But the above mentioned method is the devil's work. How can I accomplished what I get above while still making nginx/apache serve the media? Is this something that should be done at the webserver level?

• Drupal-- How to place an image in Panels 3 panels and mini-panels, w/o views or nodes?

  - by msumme

  Is it possible, through any modular functionality, to insert an image into a (mini-)panel, either through token replacement, or through an upload dialog, or through a file selection menu? Do I have to use views? Do I have to create nodes? Would the best way be to make a panel node, and then embed it in a mini-node, if I want a block-like panel that can be placed on multiple pages? I want to build a site with images in a particular layout as a small block, and make it very easy for my client to change those images in the future. I can think of some other ways to make this work, but it's driving me crazy that there seems to be no way to simply PUT an image in a mini-panel without having to upload it and hard-code an image tag. And since my client knows no HTML, coding it this way makes it un-helpful for him. And this mini-panel block is going to be used on a number of pages, and needs to be easily modified. I have been googling for about 45 minutes, and come up with nothing useful. EDIT: OR EVEN just put ONLY one image from an image field w/ multiple values in a panel region on a panel node?

• multiple redirect??

  - by Ryan Pitts

  Ok, i won't go into the full details (too much to explain) but here is what i am trying to do. I have a button on a webpage (we'll call page-1) that links to a page (we'll call it page-2). This page opens in the same window. However, i need the page (page-2) that opens to open up a new window with another page (we'll call this one page-3) when it loads. So virtually when you click the initial button (on page-1) it will go to a new page (page-2) AND a window will open as well with a different page (page-3). This is where it gets tricky. I need page-2 to automatically redirect back to page-1 after it launches page-3. Is this possible and if so, how?? Could it be a JQuery thing? Please just give some answers...i know this is way crazy and a huge workaround - but this is my last resort for this particular website. I have to do it this way because of the lack of control over some of the code.

• How can I remove certain characters from inside angle-brackets, leaving the characters outside alone

  - by Iain Fraser

  Edit: To be clear, please understand that I am not using Regex to parse the html, that's crazy talk! I'm simply wanting to clean up a messy string of html so it will parse Edit #2: I should also point out that the control character I'm using is a special unicode character - it's not something that would ever be used in a proper tag under any normal circumstances Suppose I have a string of html that contains a bunch of control characters and I want to remove the control characters from inside tags only, leaving the characters outside the tags alone. For example Here the control character is the numeral "1". Input The quick 1<strong>orange</strong> lemming <sp11a1n 1class1='jumpe111r'11>jumps over</span> 1the idle 1frog Desired Output The quick 1<strong>orange</strong> lemming <span class='jumper'>jumps over</span> 1the idle 1frog So far I can match tags which contain the control character but I can't remove them in one regex. I guess I could perform another regex on my matches, but I'd really like to know if there's a better way. My regex Bear in mind this one only matches tags which contain the control character. <(([^>])*?`([^>])*?)*?> Thanks very much for your time and consideration. Iain Fraser

• How to prevent external translation of a movieclip object on stage in AS3?

  - by Aaron H.

  I have a MovieClip object, which is exported for actionscript (AS3) in an .swc file. When I place an instance of the clip on the stage without any modifications, it appears in the upper left corner, about half off stage (i.e. only the lower right quadrant of the object is visible). I understand that this is because the clip has a registration point which is not the upper left corner. If you call getBounds() on the movieclip you can get the bounds of the clip (presumably from the "point" that it's aligned on) which looks something like (left: -303, top: -100, right: 303, bottom: 100), you can subtract the left and top values from the clip x and y: clip.x -= bounds.left; clip.y -= bounds.top; This seems to properly align the clip fully on stage with the top left of the clip squarely in the corner of the stage. But! Following that logic doesn't seem to work when aligning it on the center of the stage! clip.x = (stage.stageWidth / 2); etc... This creates the crazy parallel universe where the clip is now down in the lower right corner of the stage. The only clue I have is that looking at: clip.transform.matrix and clip.transform.concatenatedMatrix matrix has a tx value of 748 (half of stage height) ty value of 426 (Half of stage height) concatenatedMatrix has a tx value of 1699.5 and ty value of 967.75 That's also obviously where the movieclip is getting positioned, but why? Where is this additional translation coming from?

• How to setup OpenGL camera for a racing game

  - by vian

  I need the view to show the road polygon (a rectangle 3.f * 100.f) with a vanishing point for a road being at 3/4 height of the viewport and the nearest road edge as a viewport's bottom side. See Crazy Taxi game for an example of what I wish to do. I'm using iPhone SDK 3.1.2 default OpenGL ES project template. I setup the projection matrix as follows: glMatrixMode(GL_PROJECTION); glLoadIdentity(); glFrustumf(-2.25f, 2.25f, -1.5f, 1.5f, 0.1f, 1000.0f); Then I use glRotatef to adjust for landscape mode and setup camera. glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glRotatef(-90, 0.0f, 0.0f, 1.0f); const float cameraAngle = 45.0f * M_PI / 180.0f; gluLookAt(0.0f, 2.0f, 0.0f, 0.0f, 0.0f, 100.0f, 0.0f, cos(cameraAngle), sin(cameraAngle)); My road polygon triangle strip is like this: static const GLfloat roadVertices[] = { -1.5f, 0.0f, 0.0f, 1.5f, 0.0f, 0.0f, -1.5f, 0.0f, 100.0f, 1.5f, 0.0f, 100.0f, }; And I can't seem to find the right parameters for gluLookAt. My vanishing point is always at the center of the screen.

• CommandBuilder and SqlTransaction to insert/update a row

  - by Jesse

  I can get this to work, but I feel as though I'm not doing it properly. The first time this runs, it works as intended, and a new row is inserted where "thisField" contains "doesntExist" However, if I run it a subsequent time, I get a run-time error that I can't insert a duplicate key as it violate the primary key "thisField". static void Main(string[] args) { using(var sqlConn = new SqlConnection(connString) ) { sqlConn.Open(); var dt = new DataTable(); var sqlda = new SqlDataAdapter("SELECT * FROM table WHERE thisField ='doesntExist'", sqlConn); sqlda.Fill(dt); DataRow dr = dt.NewRow(); dr["thisField"] = "doesntExist"; //Primary key dt.Rows.Add(dr); //dt.AcceptChanges(); //I thought this may fix the problem. It didn't. var sqlTrans = sqlConn.BeginTransaction(); try { sqlda.SelectCommand = new SqlCommand("SELECT * FROM table WITH (HOLDLOCK, ROWLOCK) WHERE thisField = 'doesntExist'", sqlConn, sqlTrans); SqlCommandBuilder sqlCb = new SqlCommandBuilder(sqlda); sqlda.InsertCommand = sqlCb.GetInsertCommand(); sqlda.InsertCommand.Transaction = sqlTrans; sqlda.DeleteCommand = sqlCb.GetDeleteCommand(); sqlda.DeleteCommand.Transaction = sqlTrans; sqlda.UpdateCommand = sqlCb.GetUpdateCommand(); sqlda.UpdateCommand.Transaction = sqlTrans; sqlda.Update(dt); sqlTrans.Commit(); } catch (Exception) { //... } } } Even when I can get that working through trial and error of moving AcceptChanges around, or encapsulating changes within Begin/EndEdit, then I begin to experience a "Concurrency violation" in which it won't update the changes, but rather tell me it failed to update 0 of 1 affected rows. Is there something crazy obvious I'm missing?

• Zend Framework cleaning default routes when adding other

  - by Renato Aquino

  I have the following problem with Zend Framework. My project has several controllers like Video,Category and Post. The VideoController has an Action called categorylist, so the default URL/Route becomes /video/categorylist Since the action requires 3 parameters I whant to add one simple route: $router->addRoute( 'categorylist', new Zend_Controller_Router_Route('categorylist/:category/:page/:per_page', array('controller' => 'video', 'action' => 'categorylist','page'=>1,'per_page'=>6,'category'=>1)) ); With this I got my URL like www.siteurl.com/categorylist/42/1/6 but, the View Helper URL got crazy, and every url for the other controllers I try to echo it´s redirected to the categorylist route. So when I try this: <?= $this->url(array("controller"=> "video", "action" =>"view",'category'=>1),null,true)?> The expected result its /video/view/category/1, but I got /categorylit only. I tryied to debug the default routes but I got an empty array. print_r($ctrl->getRouter()->getRoutes()); Does anyone have some clue about this wierd behavior? I´m using Zend Framework Version 1.9.7
