    Please see the form HTML code below <form method="post" action="register"> <div class="email"> Email <input type="text" tabindex="1" id="email" value="" name="email"> </div> </div> <div class="agreement"> <div tabindex="2" class="terms_radio"> <div onclick="changeTerm(this);" class="radio" id="terms_radio_wrapper" style="background-position: left 0pt;"> <input type="radio" id="terms" value="1" name="terms"><label for="terms">I have read and understood the ZapAV</label> </div> </div> </div> <div class="form_submit"> <input type="button" tabindex="3" value="Cancel" name="cancel"> <input type="submit" tabindex="4" value="Submit" name="submit"> </div> </form> Here I syled teh agreement check box insuch a way that radio input is completly hidden and background image is applied to the wrapper div, and onclick of the wrapper div will toggle the backgroud image as well as the checked status of teh radio input. I need to set the tabindex index on the 'terms_radio' DIV, simply tabindex="2" attribute on div is not working, Is it possible to bring the dotted border on the label for the radio input up on pressing the TAB when the cursor is at email input field?

  • Emacs hide/show support for C++ triple-slash Doxygen markup?

    - by jsyjr
    I use Doxygen's triple-slash syntax to markup my C++ code. There are two important cases which arise: 1) block markup comments which are the sole element on the line and may or may not begin flush left; e.g. class foo /// A one sentence brief description of foo. The elaboration can /// continue on for many lines. { ... }; void foo::bar /// A one sentence brief description of bar. The elaboration can /// continue on for many lines. () const { ... } 2) trailing markup comments which always follow some number of C++ tokens earlier on the first line but may still spill over onto subsequent lines; e.g. class foo { int _var1; ///< A brief description of _var1. int _var2; ///< A brief description of _var2 ///< requiring additional lines. } void foo::bar ( int arg1 ///< A brief description of arg1. , int arg2 ///< A brief description of arg2 ///< requiring additional lines. ) const { ... } I wonder what hide/show support exists to deal with these conventions. The most important cases are the block markup comments. Ideally I would like to be able to eliminate these altogether, meaning that I would prefer not to waste a line simply to indicate presence of a folded block markup comment. Instead I would like a fringe marker, a la http://www.emacswiki.org/emacs/hideshowvis.el /john

  • Search Box/Transition won't work in Firefox

    - by user2522488
    I disabled the search box on IE, because IE kept centering it over the navigation. It works in Chrome, I'm not sure about opera (and I'm not sure if I care) but it won't work in Firefox. The ease-out timing works in Firefox, but nothing else really works. I've tried other things to work around the issue, but every time I try something different, the search box's positioning gets thrown off. If you look at it in Firefox, it looks fine-- until you click on it to search. http://kissoff.weebly.com/ You can see what the search box is supposed to do if you look at it and click on it in Chrome. I'm sure the positioning is off, I'm not sure (I'm new to css). Any help is appreciated. #search {} #search input[type="text"] { background: url(search-white.png) no-repeat 10px 6px #fcfcfc; border: 1px solid #d1d1d1; position: fixed; margin-left: 350px; margin-right: 0px; margin-top: 0px; color: #bebebe; width: 150px; padding: 6px 15px 6px 35px; -webkit-border-radius: 20px; -moz-border-radius: 20px; border-radius: 20px; text-shadow: 0 2px 3px rgba(0, 0, 0, 0.1); -webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -moz-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -webkit-transition: all 0.7s ease 0s; -moz-transition: all 0.7s ease 0s; -o-transition: all 0.7s ease 0s; transition: all 0.7s ease 0s; float: right; } #search input[type="text"]:focus { width: 200px; }

  • Tiny MCE (jquery plugin version) not showing toolbar in IE (works fine in other browsers)

    - by I am Wonder
    I had an implementation working well but for some reason IE decided it was tired of playing nice. I have an advanced implementation of TinyMCE (the jquery plugin version - see http://tinymce.moxiecode.com/examples/example_23.php for details). It still works great in all browsers but IE. In IE it shows the drop-down options for Format, Font family, and Font size, but only as text.. not as a drop down normally looks. All other buttons on the toolbar are missing. (I've tried IE8 and IE8 Compatibility Mode) I get a javascript error: Syntax error Line 36 Char 1. Unfortunately the javascript is being loaded dynamically so this doesn't help me. Here is my implementation code for the TinyMCE editor: $(function () { $('#InputStuffHere').tinymce({ // General options theme: "advanced", plugins: "safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,inlinepopups,preview,media,searchreplace,contextmenu,paste,fullscreen,noneditable,visualchars,nonbreaking,template", // Theme options theme_advanced_buttons1: "bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,formatselect,fontselect,fontsizeselect,|,hr,removeformat", theme_advanced_buttons2: "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,image,|,forecolor,backcolor,|,spellchecker", theme_advanced_buttons3 : "", theme_advanced_toolbar_location: "top", theme_advanced_toolbar_align: "left", theme_advanced_statusbar_location: "bottom", theme_advanced_resizing: true, // Drop lists for link/image/media/template dialogs template_external_list_url: "lists/template_list.js", external_link_list_url: "lists/link_list.js", external_image_list_url: "lists/image_list.js", media_external_list_url: "lists/media_list.js", //initialization callback init_instance_callback: "TinyMCEReady", add_form_submit_trigger : false }); }); So... anyone seen anything like this or have any ideas for me? Thank you so much everyone!

  • Tree iterator, can you optimize this any further?

    - by Ron
    As a follow up to my original question about a small piece of this code I decided to ask a follow up to see if you can do better then what we came up with so far. The code below iterates over a binary tree (left/right = child/next ). I do believe there is room for one less conditional in here (the down boolean). The fastest answer wins! The cnt statement can be multiple statements so lets make sure this appears only once The child() and next() member functions are about 30x as slow as the hasChild() and hasNext() operations. Keep it iterative <-- dropped this requirement as the recursive solution presented was faster. This is C++ code visit order of the nodes must stay as they are in the example below. ( hit parents first then the children then the 'next' nodes). BaseNodePtr is a boost::shared_ptr as thus assignments are slow, avoid any temporary BaseNodePtr variables. Currently this code takes 5897ms to visit 62200000 nodes in a test tree, calling this function 200,000 times. void processTree (BaseNodePtr current, unsigned int & cnt ) { bool down = true; while ( true ) { if ( down ) { while (true) { cnt++; // this can/will be multiple statesments if (!current->hasChild()) break; current = current->child(); } } if ( current->hasNext() ) { down = true; current = current->next(); } else { down = false; current = current->parent(); if (!current) return; // done. } } }

  • Cannot override the CSS at this site

    - by gdanko
    This site is overriding my CSS with its own and I cannot get around it! It has style.css with "text-align: center" in the body. I have <div id="mydiv"> appended to the body and it's normally got "text-align: left". There are <ul>s and <li>s underneath #mydiv and they are inheriting the body's 'center' for some reason. I tried this and it's still not working. $('#mydiv').children().css('text-align', 'auto'); How the heck do I reclaim my CSS!? @Grillz, the HTML looks like this: <div id="mydiv"> <ul class="container"> <li rel="folder" class="category"><a href="#">category1</a> <ul><li rel="file" class="subcategory"><a href="#">subcategory1</a></li></ul> <ul><li rel="file" class="subcategory"><a href="#">subcategory2</a></li></ul> </li> <li rel="folder" class="category"><a href="#">category2</a> <ul><li rel="file" class="subcategory"><a href="#">subcategory3</a></li></ul> <ul><li rel="file" class="subcategory"><a href="#">subcategory4</a></li></ul> </li> </ul>

  • C#: Any faster way of copying arrays?

    - by Yang
    I have three arrays that need to be combined in one three-dimension array. The following code shows slow performance in Performance Explorer. Is there a faster solution? for (int i = 0; i < sortedIndex.Length; i++) { if (i < num_in_left) { // add instance to the left child leftnode[i, 0] = sortedIndex[i]; leftnode[i, 1] = sortedInstances[i]; leftnode[i, 2] = sortedLabels[i]; } else { // add instance to the right child rightnode[i-num_in_left, 0] = sortedIndex[i]; rightnode[i-num_in_left, 1] = sortedInstances[i]; rightnode[i-num_in_left, 2] = sortedLabels[i]; } } Update: I'm actually trying to do the following: //given three 1d arrays double[] sortedIndex, sortedInstances, sortedLabels; // copy them over to a 3d array (forget about the rightnode for now) double[] leftnode = new double[sortedIndex.Length, 3]; // some magic happens here so that leftnode = {sortedIndex, sortedInstances, sortedLabels};

  • Flex Sprite xy Coordinates

    - by Ian
    Hi, I have a drawing that looks more or less like the attached image. image The orange square is the currently selected selected sprite. The sprites are all draws from coordinates that i receive from XML. var sprObject:Sprite = new Sprite(); sprObject.graphics.beginFill(itemList.c.toString()); sprObject.name = strName; sprObject.graphics.moveTo(iX, iY); sprObject.graphics.lineTo(iX2, iY2); sprObject.graphics.lineTo(iX3, iY3); sprObject.graphics.lineTo(iX4, iY4); sprObject.graphics.lineTo(iX, iX); sprObject.graphics.endFill(); mainUI.addChild(sprObject); // mainUI is a mx:UIComponent g_Sprite.push(sprObject); // array of sprites. What I want to do is the following. If I'm currently on the orange square and I use my keyboard direction buttons (up/down/left/right). I want to deselect the current sprite and select the next sprite in the appropriate direction. The problem I'm having is that I cannot get the x and y coordinates of the drawn sprites. If I look in the array, the x and y coordinates of the sprites are all 0. If I can retrieve that I can write an algorithm to determine the next sprite to select. Any help would be appreciated.

  • WordPress update_post_meta values. Delete when empty or just test for ""?

    - by Scott B
    My function below, will take the values from my custom meta fields (after a post has been edited, and save or publish has been clicked) and update or insert the posted meta values. However, if the user leaves this field blank, I believe I want to delete the meta altogether (so I can test for its presence and display accordingly vs just checking for ""). For example, one of my meta options gives the user the ability to add a Custom title to their post, which when present, will populate the page's tag. However, if the field is left empty, I want to default the tag to the_title(), which is simply the Post title used to identify the page/post. Since I'm not deleting the meta on save, its always present after the first time a user enters something in there, get_post_meta($post-ID,'MyCustomTitle', true) is always true. Further, they cannot blank it out by clearing the title field and hitting publish. What am I missing in the save in order to clear the value to "" when the user clears the field? if ($_POST['MyCustomTitle']) { update_custom_meta($postID, $_POST['MyCustomTitle'], 'MyCustomTitle'); } function update_custom_meta($postID, $newvalue, $field_name) { // To create new meta if(!get_post_meta($postID, $field_name)){ add_post_meta($postID, $field_name, $newvalue); }else{ // or to update existing meta update_post_meta($postID, $field_name, $newvalue); } }

  • .htaccess file on localhost throwing an error when using a Virtual Host config on my Localhost!!

    - by Chris
    I am trying to set-up my localhost development server. I have everything working but when I try to add an .htaccess it throws this error: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. I dont know exactly why this is, this is pretty much the exact same setup as the other developers machine, but when using my .htaccess file I get that error. Here is my .htaccess file (NOTE: They are commented because I left my site with this setup. It only lets me view the index page.

  • How to accommodate for the next iPhones totally different screen resolution?

    - by mystify
    This is a programming question! Read on before you vote to close! According to Gizmodo, the next iPhone will have a new screen resolution: The 3.5-inch screen has a resolution of 960?×?640 pixels This little detail affects our apps in a heavy way. Most of the demo apps on the net have one thing in common: They position views in the believe that the screen has a fixed size of 320 x 480 pixels. So what most -if not all- developers do is: They designed everything in such a way, that a touchable area is -for example- 50 x 50 pixels big. Just enough to tap it. Things have been positioned relative to the upper left, to reach a specific position on screen - let's say the center, or somewhere at the bottom. So the big question is: How will the developers compensate their layout and graphics? Are there already solutions which can be used to calculate coordinates and sizes in a normalized manner, which then appear to be exactly the same when viewing them on a screen of any resolution, assuming at least that the aspect ration won't change? This is community wiki. Just add anything that you think is relevant to this huge problem (constant screen res was one of the main reasons why I didn't go for Android!!).

  • OCR combined with font recognition?

    - by Adam
    I have a bold idea where a user could take an image like the following and in a few seconds of processing, be able to edit a document which looks roughly the same. The software would use WhatTheFont (or something similar) to recognize the fonts used, and OCR and other software to handle the font size, color, line-spacing, and of course the text content itself. In the case of the example image, there would be three separate "textboxes" produced, each starting at the upper left corner of the text, and extending as far to the bottom right as it could before running into another text box. So the user would then see something like this: (The rectangles are just used to show the boundaries of each textbox.) From here, the user would be able to edit the text in each of these boxes to create a new document. Of course there are tons of obvious uses for such an application, especially on a mobile phone with a built in camera. So my questions are the following: I doubt the answer is yes, but does anything do this already? If I'm going to try to build this, what should I write it in? Can I use Python? What would be the best OCR libraries to start with? Is there a service other than WhatTheFont for font recognition that has better API support? Anybody want to help me build it? :) etc. etc. Update: One thing I wanted to mention (but forgot) is I would also like the background to be preserved. In other words, if the example above had an image behind the text, I'd like the document to use that image with text removed. I know this complicates things a lot because that would require some image editing techniques too (something akin to Photoshop CS5' "content-aware fill"). But if we can solve diminished reality on iPhones, I think we can figure this out!

  • Better way to compare neighboring cells in matrix

    - by HyperCube
    Suppose I have a matrix of size 100x100 and I would like to compare each pixel to its direct neighbor (left, upper, right, lower) and then do some operations on the current matrix or a new one of the same size. A sample code in Python/Numpy could look like the following: (the comparison 0.5 has no meaning, I just want to give a working example for some operation while comparing the neighbors) import numpy as np my_matrix = np.random.rand(100,100) new_matrix = np.array((100,100)) my_range = np.arange(1,99) for i in my_range: for j in my_range: if my_matrix[i,j+1] > 0.5: new_matrix[i,j+1] = 1 if my_matrix[i,j-1] > 0.5: new_matrix[i,j-1] = 1 if my_matrix[i+1,j] > 0.5: new_matrix[i+1,j] = 1 if my_matrix[i-1,j] > 0.5: new_matrix[i-1,j] = 1 if my_matrix[i+1,j+1] > 0.5: new_matrix[i+1,j+1] = 1 if my_matrix[i+1,j-1] > 0.5: new_matrix[i+1,j-1] = 1 if my_matrix[i-1,j+1] > 0.5: new_matrix[i-1,j+1] = 1 This can get really nasty if I want to step into one neighboring cell and start from it to do a similar task... Do you have some suggestions how this can be done in a more efficient manner? Is this even possible?

  • Is it okay to rely on javascript for menu layout?

    - by Ryan
    I have a website template where I do not know the number of menu items or the size of the menu items that will be required. The js below works exactly the way I want it to, however this is the most js I've every written. Are there any disadvantages or potential problems with this method that I'm not aware of because I'm a js beginner? I'm currently manually setting the padding for each site. Thank you! var width_of_text = 0; var number_of_li = 0; // measure the width of each <li> and add it to the total with, increment li counter $('li').each(function() { width_of_text += $(this).width(); number_of_li++; }); // calculate the space between <li>'s so the space is equal var padding = Math.floor((900 - width_of_text)/(number_of_li - 1)); // add the padding the all but the first <li> $('li').each(function(index) { if (index !== 0) { $(this).css("padding-left", padding); } });

  • Problem using FormLayout in Swing

    - by Dimitri
    Hi I am using the FormLayout. I just discovered it and it's powerful layout manager. I would like to layout 4 components (outlined, properties, tgraph, library) in 3 columns. I want to layout my library component on top of the outlined component in one column, the graph and the properties component in one column. But it doesn't work. Maybe I miss something. Here is my code : private void layoutComponent() { JPanel panel = new JPanel(); FormLayout layout = new FormLayout( "right:p,10dlu,300dlu,left:max(50dlu;p)", "top:pref,center:p,p"); layout.setRowGroups(new int[][]{{1,3}}); PanelBuilder builder = new PanelBuilder(layout,panel); builder.setDefaultDialogBorder(); CellConstraints constraints = new CellConstraints(); builder.add(library, constraints.xy(1, 1)); builder.add(outline,constraints.xy(1, 3)); builder.add(tgraph,constraints.xy(3, 1)); builder.add(properties,constraints.xy(4, 1)); getContentPane().add(panel);r code here } Can someone help plz.

  • Win32 reset event like synchronization class with boost C++

    - by fgungor
    I need some mechanism reminiscent of Win32 reset events that I can check via functions having the same semantics with WaitForSingleObject() and WaitForMultipleObjects() (Only need the ..SingleObject() version for the moment) . But I am targeting multiple platforms so all I have is boost::threads (AFAIK) . I came up with the following class and wanted to ask about the potential problems and whether it is up to the task or not. Thanks in advance. class reset_event { bool flag, auto_reset; boost::condition_variable cond_var; boost::mutex mx_flag; public: reset_event(bool _auto_reset = false) : flag(false), auto_reset(_auto_reset) { } void wait() { boost::unique_lock<boost::mutex> LOCK(mx_flag); if (flag) return; cond_var.wait(LOCK); if (auto_reset) flag = false; } bool wait(const boost::posix_time::time_duration& dur) { boost::unique_lock<boost::mutex> LOCK(mx_flag); bool ret = cond_var.timed_wait(LOCK, dur) || flag; if (auto_reset && ret) flag = false; return ret; } void set() { boost::lock_guard<boost::mutex> LOCK(mx_flag); flag = true; cond_var.notify_all(); } void reset() { boost::lock_guard<boost::mutex> LOCK(mx_flag); flag = false; } }; Example usage; reset_event terminate_thread; void fn_thread() { while(!terminate_thread.wait(boost::posix_time::milliseconds(10))) { std::cout << "working..." << std::endl; boost::this_thread::sleep(boost::posix_time::milliseconds(1000)); } std::cout << "thread terminated" << std::endl; } int main() { boost::thread worker(fn_thread); boost::this_thread::sleep(boost::posix_time::seconds(1)); terminate_thread.set(); worker.join(); return 0; } EDIT I have fixed the code according to Michael Burr's suggestions. My "very simple" tests indicate no problems. class reset_event { bool flag, auto_reset; boost::condition_variable cond_var; boost::mutex mx_flag; public: explicit reset_event(bool _auto_reset = false) : flag(false), auto_reset(_auto_reset) { } void wait() { boost::unique_lock<boost::mutex> LOCK(mx_flag); if (flag) { if (auto_reset) flag = false; return; } do { cond_var.wait(LOCK); } while(!flag); if (auto_reset) flag = false; } bool wait(const boost::posix_time::time_duration& dur) { boost::unique_lock<boost::mutex> LOCK(mx_flag); if (flag) { if (auto_reset) flag = false; return true; } bool ret = cond_var.timed_wait(LOCK, dur); if (ret && flag) { if (auto_reset) flag = false; return true; } return false; } void set() { boost::lock_guard<boost::mutex> LOCK(mx_flag); flag = true; cond_var.notify_all(); } void reset() { boost::lock_guard<boost::mutex> LOCK(mx_flag); flag = false; } };

  • UIViewController maintains state after being nilled

    - by Eric
    In my app, I made a BookViewController class that displays and animates the pages of a book and a MainMenuViewController class that displays a set of books the user can read. In the latter class, when the user taps on one of the books, a function is called that should create a completely new instance of BookViewController, but for some reason the instance maintains its state (i.e. it resumes from the page the user left off). How can this be if I set it to nil? What am I missing here? (Note that I'm using ARC). MainMenuViewController.m @interface MainMenuViewController () @property (strong) BookViewController *bookViewController; @end @implementation MainMenuViewController @synthesize bookViewController; -(void)bookTapped:(UIButton *)sender{ NSString *bookTitle; if(sender == book1button) bookTitle = @"book1"; else if(sender == book2button) bookTitle = @"book2"; bookViewController = nil; bookViewController = [[BookViewController alloc] initWithBookTitle:bookTitle]; [self presentViewController:bookViewController animated:YES completion:nil]; } BookViewController.h @interface BookViewController : UIViewController -(id)initWithBookTitle:(NSString *)bookTitle; @end BookViewController.m @implementation BookViewController -(id)initWithBookTitle:(NSString *)theBookTitle{ self = [super init]; if(self){ bookTitle = [NSString stringWithFormat:@"%@", theBookTitle]; [self setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; NSLog(@"init a BookViewController with bookTitle: %@", bookTitle); } return self; } Every time a book is tapped, bookTapped: is called, and thee console always prints: 2012-08-31 16:29:51.750 AppName[25713:c07] init a BookViewController with bookTitle: book1 So if a new instance of BookViewController is being created, how come it seems to be returning the old one?

  • Dynamic change .click value Jquery IE issue.

    - by user326100
    Hello guys.. it's i first time i'm asking here. Sorry if the answer is available already. I have a very small jQuery script that canges the paramether for onclick attr on a DIV. IT works like as right and left arrows for some content in the middle. BAsically i set the onclick="foo(1)" then when get clicked sld change the value 1 to 2, and keep changing everytime i click. on jQuery functio i'm using: $("#v_arrow_r").attr('onclick','').unbind().click(newclick_next); it works like a charm on FF and Chrome, but does not work on IE !!!! Argh... here the the code: if (start == 24) { var a = 0; var b = 0; } else { var a = start-6; var b = start+6; } next = "home_featured_videos(" + b + ");"; newclick_next = eval("(function(){"+next+"});"); prev = "home_featured_videos(" + a + ");"; newclick_prev = eval("(function(){"+prev+"});"); $('#video-module').css('background',''); $('#video-module').html(response); $("#v_arrow_l").attr('onclick','').unbind().click(newclick_prev); $("#v_arrow_r").attr('onclick','').unbind().click(newclick_next); The html: //CONTENT So like i said.. i define the attr onclick when page open. It work well on IE. but when i click the arrow and call the function the oncli is set to null and i add the function to .click. IE stop working. the click is dead. If anybody have idea why this is happening. Thanx in advance. Kind Regards Varois

  • Changing direction of rotation Pygame

    - by czl
    How would you change the direction of a rotating image/rect in Pygame? Applying positive and negative degree values works but it seems to only be able to rotate one direction throughout my window. Is there a way to ensure a change in direction of rotation? Perhaps change up rotation of a spinning image every 5 seconds, or if able to change the direction of the spin when hitting a X or Y axis. I've added some code below. It seems like switching movement directions is easy with rect.move_ip as long as I specify a speed and have location clause, it does what I want. Unfortunately rotation is't like that. Here I'l adding angles to make sure it spins, but no matter what I try, I'm unable to negate the rotation. def rotate_image(self): #rotate image orig_rect = self.image.get_rect() rot_image = pygame.transform.rotate(self.image, self.angle) rot_rect = orig_rect.copy() rot_rect.center = rot_image.get_rect().center rot_image = rot_image.subsurface(rot_rect).copy() return rot_image def render(self): self.screen.fill(self.bg_color) self.rect.move_ip(0,5) #Y axis movement at 5 px per frame self.angle += 5 #add 5 anglewhen the rect has not hit one of the window self.angle %= 360 if self.rect.left < 0 or self.rect.right > self.width: self.speed[0] = -self.speed[0] self.angle = -self.angle #tried to invert the angle self.angle -= 5 #trying to negate the angle rotation self.angle %= 360 self.screen.blit(self.rotate_image(),self.rect) pygame.display.flip() I would really like to know how to invert rotation of a image. You may provide your own examples.

  • Jquery conditionals, window locations, and viewdata. Oh my!

    - by John Stuart
    I have one last thing left on a project and its a doozy. Not only is this my first web application, but its the first app i used Jquery, CSS and MVC. I have no idea on how to proceed with this. What i am trying to do is: In my controller, a waste item is validated, and based on the results one of these things can happen. The validation is completed, nothing bad happens, which sets ViewData["FailedWasteId"] to -9999. Its a new waste item and the validation did not pass, which sets ViewData["FailedWasteId"] to 0. Its an existing waste item and the validation did not pass, which sets ViewData["FailedWasteId"] to the id of the waste item. This ViewData["FailedWasteId"] is set on page load using <%=Html.Hidden("wFailId", int.Parse(ViewData["WasteFailID"].ToString()))%> When the validations do not pass, then the page zooms (by window.location) to an invisible div, opens the invisible div etc. Hopefully my intentions are clear with this poor attempt at jquery. The new waste div is and the existing item divs are dynamically generated (this i know works) " So my question here is... Help? I cant even get the data to parse correctly, nor can i even get the conditionals to work. And since this happens after post, i cant get firebug to help my step through the debugger, as the script isnt loaded yet. $(document).ready(function () { var wasteId = parseInt($('#wFailId').text()); if (wasteId == -9999) { //No Issue } else if (wasteId < 0) { //Waste not saved to database } else if (wasteId == 0) { //New Waste window.location = '#0'; $('.editPanel').hide(); $('#GeneratedWasteGrid:first').before(newRow); $('.editPanel').appendTo('#edit-panel-row').slideDown('slow'); } else if (wasteId > 0) { //Waste saved to database } });

    Hi, I am using Windows Expression web to design a embedded quicktime player that plays 4 separate videos in a main frame. Yes, I am using frames. Header Frame, Left Bar frame, Footer & Main centre frame. Everything works in Explorer as it should. See the picture ![Web Frames preview in Explorer, links work, link plays dif videos when clicked.][1] <html> Untitled 1 <div style="position: absolute; width: 100px; height: 100px; z-index: 1" id="layer1"> </div> <p>This page uses frames, but your browser doesn&#39;t support them.</p> </body> </noframes> When I check it in Safari, the video is misaligned in the frame & the background color is black, which I want it white. All the links work, it's just the misalignment & background color. See the picture. ![Safari Preview][2] Firefox also works. Here's the code, page source from the Safari browser. Heres a pic of Safari misalignment. Heres the Safari Code code Please help. It may be simple but I'm a newb. I appreciate any advice from you pro's.
