  • .NET 4.0 Forms Authentication change?

    - by James Koch
    I'm seeing some new behavior in Forms Authentication after upgrading to .NET 4.0. This occurs only on IIS 6, not on 7. Background - In web.config, we configure Forms Authentication, and then use <authorization tags to globally deny anonymous/unauthenticated users access. Then we explicitly allow access to a login.aspx page using a <location tag. Generally, this works fine, as it did when we were on .NET 2.0 (3.5). The issue only occurs when we visit the root path of the site, ie "http://myserver/". Our default document is configured in IIS to be login.aspx. Under .NET 4.0, upon visiting that URL, we're redirected to "http://myserver/login.aspx?ReturnUrl=/". If you log in from here, you're logged in and returned back at the log in page (yuck). Just wanted to post this here to see if anyone else is experiencing this. It's not listed on any "breaking changes" documentation I've been able to find. Either I'm missing something, or the UrlAuthorization module has changed and is no longer "smart" about IIS default documents.

  • Second Thread Holding Up Entire Program in C# Windows Form Application

    - by Brandon
    In my windows form application, I'm trying to test the user's ability to access a remote machine's shared folder. The way I'm doing this (and I'm sure that there are better ways...but I don't know of them) is to check for the existence of a specific directory on the remote machine (I'm doing this because of firewall/other security restrictions that I'm confronted with in my organization). If the user has rights to access the shared folder, then it returns in no time at all, but if they don't, it hangs forever. To solve this, I threw the check into another thread and wait only 1000 milliseconds before determining that the share can't be hit by the user. However, when I do this, it still hangs as if it was never run in the same thread. What is making it hang and how do I fix it? I would think that the fact that it is in a separate thread would allow me to just let the thread finish on it's own in the background. Here is my code: bool canHitInstallPath = false; Thread thread = new Thread(new ThreadStart(() => { canHitInstallPath = Directory.Exists(compInfo.InstallPath); })); thread.Start(); thread.Join(1000); if (canHitInstallPath == false) { throw new Exception("Cannot hit folder: " + compInfo.InstallPath); }

  • Client-Side Dynamic Removal of <script> Tags in <head>

    - by merv
    Is it possible to remove script tags in the <head> of an HTML document client-side and prior to execution of those tags? On the server-side I am able to insert a <script> above all other <script> tags in the <head>, except one, and I would like to be able to remove all subsequent scripts. I do not have the ability to remove <script> tags from the server side. What I've tried: (function (c,h) { var i, s = h.getElementsByTagName('script'); c.log("Num scripts: " + s.length); i = s.length - 1; while(i > 1) { h.removeChild(s[i]); i -= 1; } })(console, document.head); However, the logged number of scripts comes out to only 1, since (as @ryan pointed out) the code is being executed prior to the DOM being ready. Although wrapping the code above in a document.ready event callback does enable proper calculation of the number of <script> tags in the <head>, waiting until the DOM is ready fails to prevent the scripts from loading. Is there a reliable means of manipulating the HTML prior to the DOM being ready? Background If you want more context, this is part of an attempt to consolidate scripts where no option for server-side aggregation is available. Many of the JS libraries being loaded are from a CMS with limited configuration options. The content is mostly static, so there is very little concern about manually aggregating the JavaScript and serving it from a different location. Any suggestions for alternative applicable aggregation techniques would also be welcome.

  • 1. I fill out a form & click submit. 2. I get the results page. Goal: Get the same results without f

    - by Chris
    This is my first time posting - I greatly appreciate any and all guidance on this subject. Background: I am building a Real Estate web site. I would like to use the free IDX data provided by my local MLS board. The MLS board does not allow me the option of displaying a predefined search and only provides me with a link to the search field. after filling out the search field, I am able to view the results. Goal: I would like to bypass this step and frame the results page into a GoDaddy website I am building, which supports HTML. Here is a link to the search page: http://fgcmls.rapmls.com/scripts/mgrqispi.dll?APPNAME=Fortmyers&PRGNAME=MLSLogin&ARGUMENT=vBSJvLQtMcbg7F0O0KnXDiggv%2F12B0S6Ss9wv4510QA%3D&KeyRid=1 I am trying to only show the listings that appear in my neighborhood. Options include: 1. Property Type - Residential 2. GEO Area - FM11 3. Developments: Fiddlesticks Country Club Once this criteria is entered, I have the page needed to make this project work. Thank all of you for taking the time to read this and for the time you spend helping me out. Best regards, Chris

  • Automatic tracking algorithm

    - by nico
    Hi everyone, I'm trying to write a simple tracking routine to track some points on a movie. Essentially I have a series of 100-frames-long movies, showing some bright spots on dark background. I have ~100-150 spots per frame, and they move over the course of the movie. I would like to track them, so I'm looking for some efficient (but possibly not overkilling to implement) routine to do that. A few more infos: the spots are a few (es. 5x5) pixels in size the movement are not big. A spot generally does not move more than 5-10 pixels from its original position. The movements are generally smooth. the "shape" of these spots is generally fixed, they don't grow or shrink BUT they become less bright as the movie progresses. the spots don't move in a particular direction. They can move right and then left and then right again the user will select a region around each spot and then this region will be tracked, so I do not need to automatically find the points. As the videos are b/w, I though I should rely on brigthness. For instance I thought I could move around the region and calculate the correlation of the region's area in the previous frame with that in the various positions in the next frame. I understand that this is a quite naïve solution, but do you think it may work? Does anyone know specific algorithms that do this? It doesn't need to be superfast, as long as it is accurate I'm happy. Thank you nico

  • MKL Accelerated Math Libraries for Java...

    - by Kaopua
    I've looked at the related threads on StackOverflow and Googled with not much luck. I'm also very new to Java (I'm coming from a C# and .NET background) so please bear with me. There is so much available in the Java world it's pretty overwhelming. I'm starting on a new Java-on-Linux project that requires some heavy and highly repetitious numerical calculations (i.e. statistics, FFT, Linear Algebra, Matrices, etc.). So maximizing the performance of the mathematical operations is a requirement, as is ensuring the math is correct. So hence I have an interest in finding a Java library that perhaps leverages native acceleration such as MKL, and is proven (so commercial options are definitely a possibility here). In the .NET space there are highly optimized and MKL accelerated commercial Mathematical libraries such as Centerspace NMath and Extreme Optimization. Is there anything comparable in Java? Most of the math libraries I have found for Java either do not seem to be actively maintained (such as Colt) or do not appear to leverage MKL or other native acceleration (such as Apache Commons Math). I have considered trying to leverage MKL directly from Java myself (e.g. JNI), but me being new to Java (let alone interoperating between Java and native libraries) it seemed smarter finding a Java library that has already done this correctly, efficiently, and is proven. Again I apologize if I am mistaken or misguided (even in regarding any libraries I've mentioned) and my ignorance of the Java offerings. It's a whole new world for me coming from the heavily commercialized Microsoft stock so I could easily be mistaken on where to look and regarding the Java libraries I've mentioned. I would greatly appreciate any help or advice.

  • problem loading texture with transparency with OpenGL ES and Android

    - by Evan Kimia
    Im trying to load an image that has background transparency that will be layered over another texture. When i try and load it, all i get is a white screen. The texture is 512 by 512, and its saved in photoshop as a 24 bit PNG (standard PNG specs in the Photoshop Save for Web and Devices config window). Any idea why its not showing? The texture without transparency shows without a problem. Here is my loadTextures method: public void loadGLTexture(GL10 gl, Context context) { //Get the texture from the Android resource directory Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.m1); Bitmap normalScheduleLines = BitmapFactory.decodeResource(context.getResources(), R.drawable.m1n); //Generate texture pointers... gl.glGenTextures(3, textures, 0); //...and bind it to our array gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[1]); //Create Nearest Filtered Texture gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR_MIPMAP_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL11.GL_TEXTURE_2D, GL11.GL_GENERATE_MIPMAP, GL11.GL_TRUE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); //Bind our normal schedule bus map lines gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[0]); //Create Nearest Filtered Texture gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR_MIPMAP_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL11.GL_TEXTURE_2D, GL11.GL_GENERATE_MIPMAP, GL11.GL_TRUE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_RGBA, normalScheduleLines, 0); normalScheduleLines.recycle(); }

  • What is the best way to call a method right AFTER a form loads?

    - by Jordan S
    I have a C# windows forms application. The way I currently have it set up, when Form1_Load() runs it checks for recovered unsaved data and if it finds some it prompts the user if they want to open that data. When the program runs it works alright but the message box is shown right away and the main program form (Form1) does not show until after the user clicks yes or no. I would like the Form1 to pop up first and then the message box prompt. Now to get around this problem before I have created a timer in my Form, started the timer in the Form1_Load() method, and then performed the check and user prompt in the first Timer Tick Event. This technique solves the problem but is seems like there might be a better way. Do you guys have any better ideas? Edit: I think I have also used a background worker to do something similar. It just seems kinda goofy to go through all the trouble of invoking the method to back to the form thread and all that crap just to have it delayed a couple milliseconds!

  • How to create a semi transparent window in WPF that allows mouse events to pass through

    - by RMK
    I am trying to create an effect similar to the Lights out /lights dim feature in Adobe Lightroom (http://www.youtube.com/watch?v=87hNd3vaENE) except in WPF. What I tried was to create another window over-top of my existing window, make it transparent and put a semi transparent Path geometry on it. But I want mouse events to be able to pass through this semi transparent window (on to windows below). This is a simplified version of what I have: <Window x:Class="LightsOut.MaskWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" AllowsTransparency="True" WindowStyle="None" ShowInTaskbar="False" Topmost="True" Background="Transparent"> <Grid> <Button HorizontalAlignment="Left" Height="20" Width="60">click</Button> <Path IsHitTestVisible="False" Stroke="Black" Fill="Black" Opacity="0.3"> <Path.Data> <RectangleGeometry Rect="0,0,1000,1000 "/> </Path.Data> </Path> </Grid> The window is fully transparent, so on places where the Path doesn't cover, mouse events pass right through. So far so good. The IsHitTestvisible is set to false on the path object. So mouse events will pass through it to other controls on the same form (ie you can click on the Button, because it is on the same form). But mouse events wont pass through the Path object onto windows that are below it. Any ideas? Or better ways to solve this problem? Thanks.

  • Mac vs. Windows Browser Font Height Rendering Issue

    - by cdmckay
    I'm using a custom font and the @font-face tag. In Windows, everything looks great, regardless of whether it's Firefox, Chrome, or IE. On Mac, it's a different story. For some reason, the Mac font renderer thinks the font is a lot shorter than it is. For example, consider this test code (live example here): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Webble</title> <style type="text/css"> @font-face { font-family: "Bubbleboy 2"; src: url("bubbleboy-2.ttf") format('truetype'); } body { font-family: "Bubbleboy 2"; font-size: 30px; } div { background-color: maroon; color: yellow; height: 100px; line-height: 100px; } </style> </head> <body> <div>The quick brown fox jumped over the lazy dog.</div> </body> </html> Open it on Windows Firefox and on Mac Firefox. Use your mouse to select it. On Windows, you'll notice it fully selects the font. On Mac, it only selects about half the font. If you look at what it is selecting, you'll see that that part has been centered, instead of the full height of the font. Is there anyway to fix this rather large discrepancy?

  • Passing an ActionScript JPG Byte Array to Javscript (and eventually to PHP)

    - by Gus
    Our web application has a feature which uses Flash (AS3) to take photos using the user's web cam, then passes the resulting byte array to PHP where it is reconstructed and saved on the server. However, we need to be able to take this web application offline, and we have chosen Gears to do so. The user takes the app offline, performs his tasks, then when he's reconnected to the server, we "sync" the data back with our central database. We don't have PHP to interact with Flash anymore, but we still need to allow users to take and save photos. We don't know how to save a JPG that Flash creates in a local database. Our hope was that we could save the byte array, a serialized string, or somehow actually persist the object itself, then pass it back to either PHP or Flash (and then PHP) to recreate the JPG. We have tried: - passing the byte array to Javascript instead of PHP, but javascript doesn't seem to be able to do anything with it (the object seems to be stripped of its methods) - stringifying the byte array in Flash, and then passing it to Javascript, but we always get the same string: ÿØÿà Now we are thinking of serializing the string in Flash, passing it to Javascript, then on the return route, passing that string back to Flash which will then pass it to PHP to be reconstructed as a JPG. (whew). Since no one on our team has extensive Flash background, we're a bit lost. Is serialization the way to go? Is there a more realistic way to do this? Does anyone have any experience with this sort of thing? Perhaps we can build a javascript class that is the same as the byte array class in AS?

  • How can I get a static URL to a map image using the Google Static Maps API?

    - by Argote
    === BACKGROUND === Hello, so I've published a Web-App (still in "Beta") which uses the Flickr API to get information for the photos of a particular Flickr user and generates IPB code to post any of his/her images. While Flickr now gives you the IPB code to show the image and link back to the photo site directly on its site, my App also has the option of embeding the title, description, select EXIF data, location information, etc. into the post for the IPB forum. === PROBLEM === I've most recently added the option to integrate a Google Maps image of the photo's geolocation data into the post by using the Google Static Maps API. The problem is that the image URL I have is in the following form (including IPB [IMG] tags): [IMG]http://maps.google.com/maps/api/staticmap?zoom=16&size=600x600&maptype=hybrid&markers=19.387687,-99.251732&sensor=false[/IMG] Which shows this example image (In practice the image size is user selectable): However, some IPB forums seem to not support dyamic image URLs which gives me a broken image, I'd like to replace the [IMG]http://maps.google.com/maps/api/staticmap?zoom=16&size=600x600&maptype=hybrid&markers=19.387687,-99.251732&sensor=false[/IMG] with something like [IMG]http://maps.google.com/maps/api/staticmap/map0000001.png[/IMG] which should be supported by all IPB forums. Thanks in advance for your help. In case you're interested, the most recent "released" version of my Web-App can be found here: http://flickr.argote.mx/ (The changes I mention here are still on local development server).

  • How do you ensure a <td> is exactly 200px tall?

    I have a table with an image inside: <table style="border: 3px solid rgb(0, 0, 0); width: 800px; background-color: rgb(255, 255, 255); margin-left: auto; margin-right: auto; border-collapse: collapse;"> <tbody> <tr> <td style="text-align: center; padding: 0px; margin: 0px;"><img style="width: 800px; height: 200px; border: 0px;" alt="Logo" src="logo.png"> </td> </tr> </tbody> </table> No matter what I do, there is still a little sliver of white at the bottom of the image. A quick check with Chrome's Inspector reveals that the td has a height of 204px! How can I force the td to be the same height as the image? As you can see above, I've tried all sorts of things...

  • Directly call distutils' or setuptools' setup() function with command name/options, without parsing

    - by Ryan B. Lynch
    I'd like to call Python's distutils' or setuptools' setup() function in a slightly unconventional way, but I'm not sure whether distutils is meant for this kind of usage. As an example, let's say I currently have a 'setup.py' file, which looks like this (lifted verbatim from the distutils docs--the setuptools usage is almost identical): from distutils.core import setup setup(name='Distutils', version='1.0', description='Python Distribution Utilities', author='Greg Ward', author_email='[email protected]', url='http://www.python.org/sigs/distutils-sig/', packages=['distutils', 'distutils.command'], ) Normally, to build just the .spec file for an RPM of this module, I could run python setup.py bdist_rpm --spec-only, which parses the command line and calls the 'bdist_rpm' code to handle the RPM-specific stuff. The .spec file ends up in './dist'. How can I change my setup() invocation so that it runs the 'bdist_rpm' command with the '--spec-only' option, WITHOUT parsing command-line parameters? Can I pass the command name and options as parameters to setup()? Or can I manually construct a command line, and pass that as a parameter, instead? NOTE: I already know that I could call the script in a separate process, with an actual command line, using os.system() or the subprocess module or something similar. I'm trying to avoid using any kind of external command invocations. I'm looking specifically for a solution that runs setup() in the current interpreter. For background, I'm converting some release-management shell scripts into a single Python program. One of the tasks is running 'setup.py' to generate a .spec file for further pre-release testing. Running 'setup.py' as an external command, with its own command line options, seems like an awkward method, and it complicates the rest of the program. I feel like there may be a more Pythonic way.

  • Load XML file on seperate thread, overwrite old , and save.

    - by Luis Tovar
    Hey everyone... so Im trying to figure out how to do this. I have bounced around alot of forums to try and find my answer, but no success. Either their process it too complicated for me to understand, or is just overkill. What I am trying to do is this. I have an XML file within my app. Its a 500k xml file that i dont want the user to have to wait on when loading. SO... I put it in my app which kills the load time, and makes the app available offline. What i want to do is, when the app loads, in the background (seperate thread) download the SAME xml file which MIGHT be updated with new data. Once the xml file is complete, i want to REPLACE the xml file that was used to load the file. Any suggestions or code hints would be greatly appreciated. Thanks in advance!

  • Create PDF from HTML page with formatting retained in PDF in ASP.Net

    I am trying to convert an HTML page to a PDF using iTextSharp.dll in ASP.Net. I am able to convert the contents to my PDF , but the problem is that the Formatting of HTML page (which is inline) get removed from my PDF created. For instance I have the following code block to be formatted from my HTML page to PDF. <table style="width:90%; float:left; background:#dddddd; padding:15px; border:1px solid #000; color:#000;"><tr><td style="text-transform:uppercase; font-size:14px;font-weight:bold;">SPECIAL DELIVERY FOR:</td></tr><tr><td style="padding-left:40px; font-size:12px; color:#4e4e4e;">Name: #CustomerName# <br /><br /><label> <b>Date: #CreatedOn# </b></label><br /> </td></tr> </table> I have to format my PDF with much more HTML codes like this. I have used the Stylesheet class also, but that was not much of help.

  • Browser relative positioning with jQuery and CutyCapt

    - by Acoustic
    I've been using CutyCapt to take screen shots of several web pages with great success. My challenge now is to paint a few dots on those screen shots that represent where a user clicked. CutyCapt goes through a process of resizing the web page to the scroll width before taking a screen shot. That's extremely useful because you only get content and not much (if any) of the page's background. My challenge is trying to map a user's mouse X coordinates to the screen shot. Obviously users have different screen resolutions and have their browser window open to different sizes. The image below shows 3 examples with the same logo. Assume, for example, that the logo is 10 pixels to the left edge of the content area (in red). In each of these cases, and for any resolution, I need a JavaScript routine that will calculate that the logo's X coordinate is 10. Again, the challenge (I think) is differing resolutions. In the center-aligned examples, the logo's position, as measured from the left edge of the browser (in black), differs with changing browser size. The left-aligned example should be simple as the logo never moves as the screen resizes. Can anyone think of a way to calculate the scrollable width of a page? In other words, I'm looking for a JavaScript solution to calculate the minimum width of the browser window before a horizontal scroll bar shows up. Thanks for your help!

  • How to get the actual address of a pointer in C?

    - by Airjoe
    BACKGROUND: I'm writing a single level cache simulator in C for a homework assignment, and I've been given code that I must work from. In our discussions of the cache, we were told that the way a small cache can hold large addresses is by splitting the large address into the position in the cache and an identifying tag. That is, if you had an 8 slot cache but wanted to store something with address larger than 8, you take the 3 (because 2^3=8) rightmost bits and put the data in that position; so if you had address 22 for example, binary 10110, you would take those 3 rightmost bits 110, which is decimal 5, and put it in slot 5 of the cache. You would also store in this position the tag, which is the remaining bits 10. One function, cache_load, takes a single argument, and integer pointer. So effectively, I'm being given this int* addr which is an actual address and points to some value. In order to store this value in the cache, I need to split the addr. However, the compiler doesn't like when I try to work with the pointer directly. So, for example, I try to get the position by doing: npos=addr%num_slots The compiler gets angry and gives me errors. I tried casting to an int, but this actually got me the value that the pointer was pointing to, not the numerical address itself. Any help is appreciated, thanks!

  • Extract attributes from NSManagedObject array.

    - by Pavel Peroutka
    NSFetchRequest *req = [NSFetchRequest init]; NSEntityDescription *descr = [NSEntityDescription entityForName:@"City" inManagedObjectContext:context]; [req setEntity:descr]; NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"streetName" ascending:YES]; [req setSortDescriptors:[NSArray arrayWithObject:sort]]; [sort release]; //fetch NSError *error; NSArray *result = [context executeFetchRequest:req error:&error]; //extract names NSMutableArray *streets = [[NSMutableArray alloc] init]; for () { ??? = [array objectAtIndex:i]; [streets addObject:name]; } I expected Core Data to be little more intuitive. I am new in it and I could use some help. I fetched all objects(rows) from the entity (table) City. Now I have an array of objects. From the array I need to extract the attribute “streetName” to an array which will feed the picker. I figured I need to do it in the loop but I could not figure out the way to do it. Please help. I have a background with SQL but Core Data is still a big mystery to me. Is there any publication which would take a SQL statement and show comparable Core Data syntax? Thanks.

  • ProtoInclude for fields ?

    - by Big
    I have a simple object [ProtoContract] public class DataChangedEventArgs<T> : EventArgs { private readonly object key; private readonly T data; private readonly DataChangeType changeType; ///<summary> /// Key to identify the data item ///</summary> public object Key { get { return key; } } [ProtoMember(2, IsRequired = true)] public T Data { get { return data; } } [ProtoMember(3, IsRequired = true)] public DataChangeType ChangeType { get { return changeType; } } and I have a problem with the key. Its type is object, but it can be either int, long or string. I would intuitively use a ProtoInclude attribute to say "expect these types" but unfortunately they are class only attribute. Does anybody has any idea how I could work around this ? For background, the public object Key is here for historical reasons (and all over the place) so I would very much like to avoid the mother of all refactorings ;-) Any chance I could get this to Serialize, even force it to Serialize as a string ?

  • Drag/drop problem (draggable in position:relative parent)

    - by MackDaddy
    Here's the scenario, I'm using prototype and scriptaculous, but I believe jquery would have the same issue. I have a list draggable images in a relatively positioned div. The problem is I can't drag the images out of the parent div... well... you can, they're just not visible. If you remove the position:relative on the parent div, it works just fine, I can drag items out of the div perfectly. However because of this little IE7 bug: http://snook.ca/archives/html%5Fand%5Fcss/position%5Frelative%5Foverflow%5Fie/ that position:relative is required. IS there another work around to this bug that does not require setting position? I've tried playing with z-index and everything I can think of to no avail. Here's the CSS for the box: #products{ width: 680px; height: 400px; border: 1px solid gray; /*background-color: #66FF00;*/ overflow-y: scroll; overflow-x: hidden; font-family:"Helvetica Neue","Helvetica"; font-size:12px; font-weight:bold; position: relative; } If you would like to see this bug in action, you can visit it here: http://twinmed-dev.com/template%5Fadd.php. Try searching for an item like "gloves" then adding it to the cart below. Thanks for any help.
