  • Position absolute for rounded corners and problems in IE6

    - by danit
    Im using position absolute to give the top left corner of a DIV a rounded corner. HTML: <div id="MyDiv"> Some content <div class="topLeft">&nbsp</div> </div> CSS: #MyDiv { position: relative; padding: 12px; background: #fff url('graident.png') repeat-x top left; } .topLeft { position: absolute; top: 0; right: 0; width: 10px; height: 10px; background: transparent url('corner.png') no-repeat top right; } This works fine in all browsers expcept IE6. In IE6 the corner.png image seems to be about 1px out at the top corner, essentially not top: 0; and right: 0; but more like top: 1px; right: 1px; Can anyone explain why this might be happening only in IE6?

  • Horizontally-centering an absolute position to match a relative position

    - by Chris Vandevelde
    I'm trying to make a div box, containing various elements, fixed at the top of the page once the page has been scrolled so that the box would normally be out of view, but scroll normally until that point (like the behaviour at http://perldoc.perl.org/perl.html). The conditionally-fixed part is pretty simple to implement (set the position to "fixed" once the user has scrolled past a certain point, and "static" once it's scrolled back up), but I'm having trouble with the positioning and dimensions; it screws up if I'm not specifying an absolute position (if I'm using % or "auto", rather than px, em, cm, etc.) or it, confusingly, left-aligns if the box is less than the width of the page. I can understand why, more or less, I'm just trying to fix it. My strategy right now is to have an invisible DIV hold the place of the box and use Prototype's clonePosition() function to hold its position, but it doesn't seem to work for some reason. Neither does copying the margin from one element to the other. Any ideas? Bonus points and eternal gratitude if you can come up with an idea that will adjust itself with the browser window (like auto margins) without setting an onresize event.

    - by davey
    I'm trying to vertically align a h1 element and p in the middle of a div floated left but they end up next to each other vertically aligned. Im pretty sure it to do with the table-cell display but don't know how to vertically align without it. my code gives me: . . Heading Paragraph . . I want: . .

  • Expression Blend doesn't recognize command objects declared in code behind file

    - by Brian Ensink
    I have a WPF UserControl. The code behind file declares some RoutedUICommand objects which are referenced in the XAML. The application builds and runs just fine. However Expression Blend 3 cannot load the XAML in the designer and gives errors like this one: The member "ResetCameraCommand" is not recognized or accessible. The class and the member are both public. Building and rebuilding the project in Blend and restarting Blend hasn't helped. Any ideas what the problem is? Here are fragments of my XAML ... <UserControl x:Class="CAP.Visual.CameraAndLightingControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:CAP.Visual;assembly=VisualApp" Height="100" Width="700"> <UserControl.CommandBindings> <CommandBinding Command="local:CameraAndLightingControl.ResetCameraCommand" Executed="ResetCamera_Executed" CanExecute="ResetCamera_CanExecute"/> </UserControl.CommandBindings> .... ... and the code behind C# namespace CAP.Visual { public partial class CameraAndLightingControl : UserControl { public readonly static RoutedUICommand ResetCameraCommand; static CameraAndLightingControl() { ResetCameraCommand = new RoutedUICommand("Reset Camera", "ResetCamera", typeof(CameraAndLightingControl)); }

  • Image appearing in the wrong place.

    - by Luke
    I have a list that I want to precede on each line with a small image. The CSS: .left div.arrow{background-image: url(../images/design/box.png); float:left; height:15px; width:15px; margin-right:2px;} .left a.list:link, a:visited, a:active {color:black; font-size:0.8em; text-decoration:none; display:block; float:left;} The HTML: <div class="panel">My quick links</div> <div class="arrow"></div> <a href="/messages.php?p=new" class="list">Send a new message</a> <br /> <div class="arrow"></div> <a href="/settings.php#password" class="list">Change my password</a> <br /> <div class="arrow"></div> <a href="/settings.php#picture" class="list">Upload a new site image</a> <br /> As you can see, each image should go before the writing. On the first line, the text "Send a new message" has the preceeding image. However, each line afterwards has the image at the end. So "Send a new message" has an image at the start and finish. It is like the images are staying at the end of the previous line. Any ideas?

  • Problems using (building?) native gem extensions on OS X

    - by goodmike
    I am having trouble with some of my rubygems, in particular those that use native extensions. I am on a MacBookPro, with Snow Leopard. I have XCode 3.2.1 installed, with gcc 4.2.1. Ruby 1.8.6, because I'm lazy and a scaredy cat and don't want to upgrade yet. Ruby is running in 32-bit mode. I built this ruby from scratch when my MBP ran OSX 10.4. When I require one of the affected gems in irb, I get a Load Error for the gem extension's bundle file. For example, here's nokogigi dissing me: > require 'rubygems' = true > require 'nokogiri' LoadError: Failed to load /usr/local/lib/ruby/gems/1.8/gems/nokogiri-1.4.1/lib/nokogiri/nokogiri.bundle This is also happening with the Postgres pg and MongoDB mongo gems. My first thought was that the extensions must not be building right. But gem install wasn't throwing any errors. So I reinstalled with the verbose flag, hoping to see some helpful warnings. I've put the output in a Pastie, and the only warning I see is a consistent one about "passing argument n of ‘foo’ with different width due to prototype." I suspect that this might be an issue from upgrading to Snow Leopard, but I'm a little surprised to experience it now, since I've updated my XCode. Could it stem from running Ruby in 1.8.6? I'm embarrassed that I don't know quite enough about my Mac and OSX to know where to look next, so any guidance, even just a pointer to some document I couldn't find via Google, would be most welcome.

  • css style remains after click

    - by rod
    Hi All, I have a simple test page with a single styled button. I'm using a:hover when you hover over the button. However, when you click the button the a:hover style remains until I click on something else. How would I fix this and why is this happening? Thanks, rod. <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <% using (Ajax.BeginForm(new AjaxOptions { })) { %> <div id="detailActions"> <a href="#">Delete User</a> </div> <% } %> </asp:Content> My CSS: #detailActions { margin-bottom: 7px; padding: 3px 0px 5px 0px; } #detailActions { padding: 1px 7px 1px 7px; margin: 0px 5px 0px 0px; border: solid 1px gray; background-color: #ADD8E6; cursor: pointer; width: auto !important; font-weight: bold; text-decoration: none; color: #003366; font-size: 1.2em; } #detailActions a:hover, #detailActions a:active, #detailActions a:focus { color: White; background-color: #00008B; }

  • What does it mean to say "Instance variables are not over-rided" in java?

    - by Ankit
    I am aware of the concept called field hiding in java. But still I am having a confusion in relation to instance variable being not over-ridden. According to my present knowledge, overriding a method of super-class means that the JVM will call the sub-class's over-ridden method though the super-class's method is available to the sub-class. And I read the similar thing for field hiding via the link:- Hiding Fields So, in any case we are over-ridding the instance if we change the values of the inherited instance variable in the sub-class. I am confused please help. I am using the following super-class:- public class Animal{ File picture; String food; int hunger; int width, height; int xcoord, ycoord; public void makeNoise(){ ......... } public void eat(){ ............. } public void sleep(){ .......... } public void roam(){ ............. } } It has sub-classes like Tiger, cat, dog,hippo etc. The sub-classes over-ride the makeNoise(), eat and roam() method. But each sub-class also uses a different set of values for instance variables. So as per my confusion, I am kind-of overriding all the instance variables and 3 methods of the super-class Animal; and I still have the super-class instance variables available to the sub-class with the use of the super keyword.

  • Aligning inputs on bootstrap using the Fluid Grid System

    - by sguha
    I am creating a form that requires the user to input their name and email address. The first line of the form has two inputs side by side for each part of the name and the 2nd line has one input for the email address that should be the same width as the first line combined. I'm trying to use the fluid grid system but can't line up the 2nd row with the first. <form action="/subscriptions" method="post"> <fieldset> <div class="control-group"> <label class="control-label" for="name">Name</label> <div class="controls row-fluid"> <input class="span2" id="first_name" name="first_name" placeholder="First" required="required" type="text"> <input class="span2" id="last_name" name="last_name" placeholder="Last" required="required" type="text"> </div> </div> <div class="control-group"> <label class="control-label" for="email">Email</label> <div class="controls row-fluid"> <input class="span4" id="email" name="email" type="email"> </div> </div> </fieldset> </form>? http://jsfiddle.net/sguha095/v4amX/

  • Javascript/Canvas/Images scaling problem in Firefox

    - by DocTiger
    I have a problem with the context2d's drawImage function. Whenever I scale an image, it gets a dark border of one pixel, which is kind of ugly. That does only happen in Firefox, not in Opera or Webkit. Is this an antialiasing problem? For hours I studied the examples and available documentation without getting rid of it... I couldn't yet try it on another computer so maybe just maybe it's an issue with the graphics hardware/drivers. I have reproduced this effect with this minimal snippet, assuming exp.jpg is sized 200x200 pixels. <html> <body> <canvas id="canvas" width="400" height="400"></canvas> </body> <script type="text/javascript" src="../../media/pinax/js/jquery-1.3.2.min.js"></script> <script type="text/javascript" > context = $('#canvas')[0].getContext('2d'); img = new Image(); img.src = "exp.jpg"; //while (!img.complete); context.drawImage(img, 2,2,199,199); context.drawImage(img, 199,2,199,199); </script> </html>

  • Projective transformation

    - by mcwehner
    Given two image buffers (assume it's an array of ints of size width * height, with each element a color value), how can I map an area defined by a quadrilateral from one image buffer into the other (always square) image buffer? I'm led to understand this is called "projective transformation". I'm also looking for a general (not language- or library-specific) way of doing this, such that it could be reasonably applied in any language without relying on "magic function X that does all the work for me". An example: I've written a short program in Java using the Processing library (processing.org) that captures video from a camera. During an initial "calibrating" step, the captured video is output directly into a window. The user then clicks on four points to define an area of the video that will be transformed, then mapped into the square window during subsequent operation of the program. If the user were to click on the four points defining the corners of a door visible at an angle in the camera's output, then this transformation would cause the subsequent video to map the transformed image of the door to the entire area of the window, albeit somewhat distorted.

  • Call ASP.NET 2.0 Server side code from Javascript

    - by Kannabiran
    I'm struggling with this for the past 3 days. I need to call asp.net serverside code from Javascript when the user closes the browser. I'm using the following code to accomplish this. In my asp.net form I have various validation controls. Even if there are some validation errors, When I close the form the server side code works perfectly in my development box(windows 7). But the same code doesnt work in my production environment(windows server). Does it have something to do with the Validation summary or Validation controls. The button control has Causes validation set to false. So even if there is a validation error still my form will post back. Am I correct? I suspect the form is not getting post back to the server when there is a validation error. But i'm disabling all the validation controls in the javascript before calling the button click event. Can someone throw some light on this issue. There are few blogs which suggests to use JQUERY, AJAX (Pagemethods and script manager). function ConfirmClose(e) { var evtobj = window.event ? event : e; if (evtobj == e) { //firefox if (!evtobj.clientY) { evtobj.returnValue = message; } } else { //IE if (evtobj.clientY < 0) { DisablePageValidators(); document.getElementById('<%# buttonBrowserCloseClick.ClientID %>').click(); } } } function DisablePageValidators() { if ((typeof (Page_Validators) != "undefined") && (Page_Validators != null)) { var i; for (i = 0; i < Page_Validators.length; i++) { ValidatorEnable(Page_Validators[i], false); } } } //HTML <div style="display:none" > <asp:Button ID="buttonBrowserCloseClick" runat="server" onclick="buttonBrowserCloseClick_Click" Text="Button" Width="141px" CausesValidation="False" /> //Server Code protected void buttonBrowserCloseClick_Click(object sender, EventArgs e) { //Some C# code goes here }

  • Drawing an image is completely out

    Hi I'm using this code below to let a user "draw" their signature on a UIView component on my app: UIGraphicsBeginImageContext(signature.frame.size); [drawImage.image drawInRect:CGRectMake(0, 0, signature.frame.size.width, signature.frame.size.height)]; CGContextSetLineCap(UIGraphicsGetCurrentContext(), kCGLineCapRound); CGContextSetLineWidth(UIGraphicsGetCurrentContext(), 5.0); CGContextSetRGBStrokeColor(UIGraphicsGetCurrentContext(), 1.0, 0.0, 0.0, 1.0); CGContextMoveToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y); CGContextAddLineToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y); CGContextStrokePath(UIGraphicsGetCurrentContext()); CGContextFlush(UIGraphicsGetCurrentContext()); drawImage.image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext() The issue I am having is that the drawing is not only is the drawing not in line with the pointer when in use in the simulator, the image is going outside of the designated UIView compontent and is getting smaller/out of focus the more I draw, as you can see in this image: And after a few lines, showing the boundaries of the exact are of where I can draw: Any ideas on what's happening here? lastPoint.y is defined as: lastPoint.y -= 20; Any ideas on what on earth is happening here?

  • View transform seems to be ignored when animating on iphone. Why?

    - by heymon
    I have views that can be rotated, scaled and moved around the screen. I want the view to resize and be orthogonal when the user double tap's the view to edit the textview within. The code is below. Somewhere the transform is getting reset. The NSLog statement below prints the identity transform, but a print of the transform when the animation is complete in transitionDidStop reveals that the transform is what it was before I thought I set it to identity. The view resizes, but it acts like the transform was never set to identity? Any ideas/pointers? originalBounds = self.bounds; originalCenter = self.center; originalTransform = self.transform; r = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width - 70, 450); [UIView beginAnimations: nil context: NULL]; [UIView setAnimationDelegate: self]; [UIView setAnimationDidStopSelector: @selector(transitionDidStop:finished:context:)]; self.transform = CGAffineTransformIdentity; NSLog(@"%@ after set", NSStringFromCGAffineTransform([self transform])); [self setBounds: r]; [self setCenter: p]; [self setAlpha: 1.0]; [UIView commitAnimations]; [textView becomeFirstResponder];

  • Where is the "ListViewItemPlaceholderBackgroundThemeBrush" located?

    - by Dimi Toulakis
    I have a problem understanding one style definition in Windows 8 metro apps. When you create a metro style application with VS, there is also a folder named Common created. Inside this folder there is file called StandardStyles.xaml Now the following snippet is from this file: <!-- Grid-appropriate 250 pixel square item template as seen in the GroupedItemsPage and ItemsPage --> <DataTemplate x:Key="Standard250x250ItemTemplate"> <Grid HorizontalAlignment="Left" Width="250" Height="250"> <Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}"> <Image Source="{Binding Image}" Stretch="UniformToFill"/> </Border> <StackPanel VerticalAlignment="Bottom" Background="{StaticResource ListViewItemOverlayBackgroundThemeBrush}"> <TextBlock Text="{Binding Title}" Foreground="{StaticResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource TitleTextStyle}" Height="60" Margin="15,0,15,0"/> <TextBlock Text="{Binding Subtitle}" Foreground="{StaticResource ListViewItemOverlaySecondaryForegroundThemeBrush}" Style="{StaticResource CaptionTextStyle}" TextWrapping="NoWrap" Margin="15,0,15,10"/> </StackPanel> </Grid> </DataTemplate> What I do not understand here is the static resource definition, e.g. for the Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}" It is not about how you work with templates and binding and resources. Where is this ListViewItemPlaceholderBackgroundThemeBrush located? Many thanks for your help. Dimi

  • How to set margin for inner controls of WrapPanel

    - by Andrey Tagaew
    Hi Guys! I'm new in WPF and have a question. Here is an example that I'm using: <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <StackPanel> <WrapPanel Orientation="Horizontal" > <Button Content="test1" Margin="10,0" Padding="10,10" /> <Button Content="test2" Margin="10,0" Padding="10,10" /> <Button Content="test3" Margin="10,0" Padding="10,10" /> <Button Content="test4" Margin="10,0" Padding="10,10" /> <Button Content="test5" Margin="10,0" Padding="10,10" /> </WrapPanel> </StackPanel> As you can see, my wrap panel has several buttons. Each button has the same margin and padding. The question is, is there a way of setting margin and padding for wrap panel, so each element inside the wrap panel may use it values? This make the code shorter and let me specify Margin and Padding only one time instead of setting it for each control in the panel. Thank you!

  • How Can I Compress Texture in OpenGL on iPhone/iPad?

    - by nonamelive
    Hi, I'm making an iPad app which needs OpenGL to do a flip animation. I have a front image texture and a back image texture. Both the two textures are screenshots. // Capture an image of the screen UIGraphicsBeginImageContext(view.bounds.size); [view.layer renderInContext:UIGraphicsGetCurrentContext()]; image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); // Allocate some memory for the texture GLubyte *textureData = (GLubyte*)calloc(maxTextureSize*4, maxTextureSize); // Create a drawing context to draw image into texture memory CGContextRef textureContext = CGBitmapContextCreate(textureData, maxTextureSize, maxTextureSize, 8, maxTextureSize*4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast); CGContextDrawImage(textureContext, CGRectMake(0, maxTextureSize-size.height, size.width, size.height), image.CGImage); CGContextRelease(textureContext); // ...done creating the texture data [EAGLContext setCurrentContext:context]; glGenTextures(1, &textureToView); glBindTexture(GL_TEXTURE_2D, textureToView); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, maxTextureSize, maxTextureSize, 0, GL_RGBA, GL_UNSIGNED_BYTE, textureData); // free texture data which is by now copied into the GL context free(textureData); Each of the texture takes up about 8MB memory, which is unacceptable for an iPhone/iPad app. Could anyone tell me how can I compress the texture to reduce the memory. I'm a complete newbie to OpenGL. Any help would be appreciated!

  • Client-side validation breaks in IE because of PropertyProxyValidator and ScriptManager cooperation.

    - by Eugene
    The specific of the project is in using Enterpise Library for Server side validation and jQuery for client-side validation. So I have the next simple form for example: <asp:Content ID="_mainContent" ContentPlaceHolderID="MainContent" runat="server"> <script src="../../../Scripts/jquery-1.3.2.js" type="text/javascript"></script> <script src="../../../Scripts/jquery.validate.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { $("#aspnetForm").validate({ rules: { "<%= _txtProjectName.UniqueID %>": { required: true } } }); }); </script> <asp:TextBox ID="_txtProjectName" runat="server" CssClass="textBoxWithValidator_long" /> <entlib:PropertyProxyValidator id="_validatorProjectName" runat="server" ControlToValidate="_txtProjectName" PropertyName="ProjectName" SourceTypeName="LabManagement.Project.Project" /> <asp:Button CssClass="cell_InlineElement" ID="_btnSave" runat="server" Text="Save" onclick="_btnSave_Click" Width="50px" /> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"> </asp:ScriptManager> </asp:Content> The problem is in the next: client-side validation worked correctly before I needed to implement some AJAX.NET feature. So I have to add to the page ScriptManager (the last two lines in the code). But after that the next situation appeared: In InternetExplorer((7) - only in IE !!! - in Firefox everything works correctly) after clicking save button, if left the textbox ProjectName empty the client-side jquery validation appears but (!) the page submits to the server anyway. Some notes: If delete PropertyProxyValidator from the page - the client-side validation works correctly in IE but I need it for specific of the project. It seems that the problem is in the function WebForm_OnSubmit() that is inserted to the form after PropertyProxyValidator adding. ( ... <form name="aspnetForm" method="post" action="Project.aspx?TransType=NewProject" onsubmit="javascript:return WebForm_OnSubmit();" ...>) Could anyone help, please.
