  • Been asked a dozen times, but no luck from what I've read. Prevent Anchor Jumping on page load

    - by jasenmp
    I'm currently working with WP theme that can be found here: sanjay.dmediastudios.com I'm currently using 'smooth scroll' on my page, I'm attempting to have the page smoothly scroll to the requested section when coming from an external link (for instance coming from the blog page takes you to sanjay.dmediastudios.com/#portfolio) from there I want the page to start at the top and THEN scroll to the portfolio section. What's happening is it briefly displays the 'portfolio section' (anchor jump) and THEN resets to the top and scrolls down. It's driving me nuts :(. Here is the code I'm using: Click function for smooth scroll: $(function() { $('.menu li a').click(function() { if (location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') && location.hostname == this.hostname) { var target = $(this.hash); target = target.length ? target : $('[name=' + this.hash.slice(1) + ']'); if (target.length) { $root.animate({ scrollTop: target.offset().top - 75 }, 800, 'swing'); return false; } } }); //end of click function }); The page load function: $(window).on("load", function() { if (location.hash) { // do the test straight away window.scrollTo(0, 0); // execute it straight away setTimeout(function() { window.scrollTo(0, 0); // run it a bit later also for browser compatibility }, 1); } var urlHash = window.location.href.split("#")[1]; if (urlHash && $('#' + urlHash).length) $('html,body').animate({ scrollTop: $('#' + urlHash).offset().top - 75 }, 800, 'swing'); }); Any help would be MUCH appreciated.

  • JTable cells not rendering shapes properly

    - by Andrew
    I'm trying to render my JTable cells with a subclassed JPanel and the cells should appear as coloured rectangles with a circle drawn on them. When the table displays initially everything looks OK but then when a dialog or something is displayed over the cells when it is removed the cells that have been covered do not rendered properly and the circles are broken up etc. I then have to move the scroll bar or extend the window to get them to redraw properly. The paintComponent method of the component I'm using to render the cells is below: protected void paintComponent(Graphics g) { setOpaque(true); super.paintComponent(g); Graphics2D g2d = (Graphics2D) g; GradientPaint gradientPaint = new GradientPaint(new Point2D.Double(0, 0), Color.WHITE, new Point2D.Double(0, getHeight()), paintRatingColour); g2d.setPaint(gradientPaint); g2d.fillRect(0, 0, getWidth(), getHeight()); g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); g2d.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); Rectangle clipBounds = g2d.getClipBounds(); int x = new Double(clipBounds.getWidth()).intValue() - 15; int y = (new Double(clipBounds.getHeight()).intValue() / 2) - 6; if (level != null) { g2d.setColor(iconColour); g2d.drawOval(x, y, width, height); g2d.fillOval(x, y, width, height); } }

  • Java's Swing Threading

    - by nevets1219
    My understanding is that if I start up another thread to perform some actions, I would need to SwingUtilities.invokeAndWait or SwingUtilities.invokeLater to update the GUI while I'm in said thread. Please correct me if I'm wrong. What I'm trying to accomplish is relatively straightforward: when the user clicks submit, I want to (before performing any actions) disable the submit button, perform the action, and at the end of the action re-enable the button. My method to perform the action updates the GUI directly (displays results) when it gets the results back. This action basically queries a server and gets some results back. What I have so far is: boolean isRunning = false; synchronized handleButtonClick() { if ( isRunning == false ) { button.setEnabled( false ); isRunning = true; doAction(); } } doAction() { new Thread() { try { doAction(); // Concern A } catch ( ... ) { displayStackTrace( ... ); // Concern B } finally { SwingUtilities.invokeLater ( /* simple Runnable to enable button */ ); isRunning = false; } } } For both of my concerns above, do I would have to use SwingUtilities.invokeAndWait since they both will update the GUI? All GUI updates revolve around updating JTextPane. Do I need to in my thread check if I'm on EDT and if so I can call my code (regardless of whether it updates the GUI or not) and NOT use SwingUtilities.invokeAndWait?

  • Java Graphics not displaying on successive function calls, why?

    - by primehunter326
    Hi, I'm making a visualization for a BST implementation (I posted another question about it the other day). I've created a GUI which displays the viewing area and buttons. I've added code to the BST implementation to recursively traverse the tree, the function takes in coordinates along with the Graphics object which are initially passed in by the main GUI class. My idea was that I'd just have this function re-draw the tree after every update (add, delete, etc...), drawing a rectangle over everything first to "refresh" the viewing area. This also means I could alter the BST implementation (i.e by adding a balance operation) and it wouldn't affect the visualization. The issue I'm having is that the draw function only works the first time it is called, after that it doesn't display anything. I guess I don't fully understand how the Graphics object works since it doesn't behave the way I'd expect it to when getting passed/called from different functions. I know the getGraphics function has something to do with it. Relevant code: private void draw(){ Graphics g = vPanel.getGraphics(); tree.drawTree(g,ORIGIN,ORIGIN); } vPanel is what I'm drawing on private void drawTree(Graphics g, BinaryNode<AnyType> n, int x, int y){ if( n != null ){ drawTree(g, n.left, x-10,y+10 ); if(n.selected){ g.setColor(Color.blue); } else{ g.setColor(Color.gray); } g.fillOval(x,y,20,20); g.setColor(Color.black); g.drawString(n.element.toString(),x,y); drawTree(g,n.right, x+10,y+10); } } It is passed the root node when it is called by the public function. Do I have to have: Graphics g = vPanel.getGraphics(); ...within the drawTree function? This doesn't make sense!! Thanks for your help.

  • session timeout prompt asp.net

    - by renathy
    The application I am using is implementing some session timeout prompt using jquery. There is a timer that counts and if there is no user activity after predefined X minutes it shows user prompt (Your session will end soon... Continue or Logout). It uses the approach found here - http://www.codeproject.com/Articles/227382/Alert-Session-Time-out-in-ASP-Net. However, this doesn't work if user opens new tab: 1) User logs in, timer starts counting user inactivity's. 2) User clicks some link that opens in new window (for example, in our case it is a long report running). Second tab is active, there is some response (crossbacks / postbacks that doesn't end session). 3) Second browser tab is active, there is some activity that doesn't end session. 4) However, first browser tab is inactive and counter is "thinking" that session should be closed, it displays appropriate message and then logout user. This is not what we want. So the given approach is just some session timeout fix, but if user is active in another tab, then application will logout user anyway. That is not the desired thing. We have a Report Page. It functions so that it opens report in a new tab/window. And it could be run quite long. Report section take care of some callbacks, so session wont end in this tab. However, it would end in the second tab.

    the purpose is to use c++ in a useful way. i have just started programming and have made a few small applications in c and c#. my understanding is that programming for web and thing related to web is now a days a very easy task. please note this is for personnel learning not for rent a coder or any money making. an application which can run on any windows platform even win98. the application should start automatically at a scheduled time and do the following. connect to a site which displays stock prices summary (high low current open ). captures the data (excluding the other things in the site) and saves it to disk ( a sql database) please note:- internet connection is assumed to be there always. do not want to know how to make database schema or database. the stock exchange has no law prohibiting the use of the data provided on its site, but i do not want to mention the name in case i am wrong, but its for personnel private use only. the data of summary of pricing is arranged in a table such that when copied pasted to ms excel it automatically forms a table. guidance needed thank u.

  • Active State Image Display

    - by fmz
    I have some images that need to change, based not only on hover, but also on active state. If you look at the page here: http://site427.mysite4now.net/tazthedog/site1/ There are some tabs with Screen Printing Quick Links, etc. The tab image is associated with the link and displays properly. The icon in tabs defaults to the gray and turns blue on mouse over, however, I also need it to be blue on the "active" state. Here is the css: .quick-links em:hover { background: transparent url(../images/quick-links.png) 10px 9px no-repeat ; display: block ; float: left; } Here is the html: <ul class="tabs"> <li class="quick-links"> <a href="#quickLinks" id=""> <em> <span>Screen Printing Quick Links</span> </em> </a> </li> <li class="distributor-ql"> <a href="#distributorQL" id=""> <em> <span>Dealer &amp; Distributor Quick Links</span> </em> </a> </li> </ul> I tried adding a .quick-links em:active... but that doesn't maintain it. I know there is a way to keep the icon blue while in the active state, I just need a little help to understand what that is. Thanks!

  • How to Sort a TreeList in Sitecore 6 in the Source

    - by Scott
    My team uses Sitecore 6 as content management system and then .Net to interface with Sitecore API. In many of our templates we make use of a Treelist. When adding a new item to the selected items Treelist it automatically puts the item at the bottom of the list. In some lists they get very large. In most cases end users would like to see these lists sorted descending by a Date field that is part of the templates that can be added as selected to the Treelist. Programmatically on the .Net side its very easy to handle this using Linq OrderByDescending and all displays great in the site to visitors. What I am trying to figure out is how to get it to display the same in Sitecore Content Editor. I've not found anything from Google search other than there seems to be a SortBy you can specify in the source but I tried this and can't get it to have any effect. Has anyone dealt with this before? Again, main goal is to sort items in a Treelist in the Sitecore Content Editor itself. Thanks for any input anyone has.

  • How can I handle all my errors/messages in one place on an Asp.Net page?

    - by Atomiton
    Hi all, I'm looking for some guidance here. On my site I put things in Web user controls. For example, I will have a NewsItem Control, an Article Control, a ContactForm control. These will appear in various places on my site. What I'm looking for is a way for these controls to pass messages up to the Page that they exist on. I don't want to tightly couple them, so I think I will have to do this with Events/Delegates. I'm a little unclear as to how I would implement this, though. A couple of examples: 1 A contact form is submitted. After it's submitted, instead of replacing itself with a "Your mail has been sent" which limits the placement of that message, I'd like to just notify the page that the control is on with a Status message and perhaps a suggested behaviour. So, a message would include the text to render as well as an enum like DisplayAs.Popup or DisplayAs.Success 2 An Article Control queries the database for an Article object. Database returns an Exception. Custom Exception is passed to the page along with the DisplayAs.Error enum. The page handles this error and displays it wherever the errors go. I'm trying to accomplish something similar to the ValidationSummary Control, except that I want the page to be able to display the messages as the enum feels fit. Again, I don't want to tightly bind or rely a control existing on the Page. I want the controls to raise these events, but the page can ignore them if it wants. Am I going about this the right way? I'd love a code sample just to get me started. I know this is a more involved question, so I'll wait longer before voting/choosing the answers.

  • MVC design pattern in complex iPad app: is one fat controller acceptable?

    - by nutsmuggler
    I am building a complex iPad application; think of it as a scrapbook. For the purpose of this question, let's consider a page with two images over it. My main view displays my doc data rendered as a single UIImage; this because I need to do some global manipulation over them. This is my DisplayView. When editing I need to instantiate an EditorView with my two images as subviews; this way I can interact with a single image, (rotate it, scale it, move it). When editing is triggered, I hide my DisplayView and show my EditorView. In a iPhone app, I'd associate each main view (that is, a view filling the screen) to a view controller. The problem is here there is just one view controller; I've considered passing the EditorView via a modal view controller, but it's not an option (there a complex layout with a mask covering everything and palettes over it; rebuilding it in the EditorView would create duplicate code). Presently the EditorView incorporates some logic (loads data from the model, invokes some subviews for fine editing, saves data back to the model); EditorView subviews also incorporate some logic (I manipulate images and pass them back to the main EditorView). I feel this logic belongs more to a controller. On the other hand, I am not sure making my only view controller so fat a good idea. What is the best, cocoa-ish implementation of such a class structure? Feel free to ask for clarifications. Cheers.

  • Keeping user data persistent after validates_presence_of

    - by mathee
    I'm designing a question-and-answer Ruby on Rails application. After a user logs in, you can see a list of questions posed by other users. I have a link next to each of the questions to /answers/new?question_id=someNumber. That links to a page that displays the question (to remind the "answerer") above a standard form for submitting your answer. In order to display the question, I call @question = Question.find_by_id(params[:question_id]) and reference @question in the Haml view file: Question details %h2 #{h @question.title} #{h @question.description} %br/ %br/ %h1 Your answer - form_for(@answer) do |f| = f.error_messages %p = f.label :description, "Enter your response here" %br = f.text_area :description = f.hidden_field "question", :value => @question.id %p = f.submit 'Answer' The problem is that if I check validates_presence_of :description in Answer.rb, then I lose question_id if the user did not input anything into the description field when the page reloads, so I can't re-display the question for which the user is answering. How should I fix this? Is there a better way of storing the question the user is trying to answer so that I can display it above the form for entering a new answer (and perhaps in other views in the future)? If you need to see more code, please let me know.

  • Attempted GCF app for Android

    I am new to Android and am trying to create a very basic app that calculates and displays the GCF of two numbers entered by the user.

  • Getting a particular menu item from MainMenu

    - by Garry
    I have a nib (winA.xib) that contains a window. My app delegate contains an NSWindowController subclass called WinAController. WinAController has a property (NSMenu *mainMenu) that I want to point to the MainMenu. I have set it after I instantiate WinAController with this code: WinAController = [[WinAController alloc] initWithWindowNibName:@"WinA"]; WinAController.mainMenu = [NSApp mainMenu]; I have a menu item underneath the "Window" top-level menu item on MainMenu that invokes the [WinAController showWindow] method and displays WinA. I want to toggle the on/off state of this menu item depending on whether WinA is visible or not. WinAController also has another property (NSMenuItem *myMenuItem). How can I get a reference to a sub menu of the "Window" top-level menu item. The title of sub menu item I want to get is "Command". I have tried this: if (mainMenu != nil) { myMenuItem = [mainMenu itemAtIndex:[mainMenu indexOfItemWithTitle:@"Command"]]; } But it doesn't seem to work. Where am I going wrong? Thanks,

  • How do I capture Chinese input via SCIM with STDIN in Perl?

    - by KCArpe
    I use SCIM on Linux for Chinese and Japanese language input. Unfortunately, when I try to capture input using Perl's STDIN, the input is crazy. As roman characters are typed, SCIM tries to guess the correct final characters. ^H (backspace) codes are used to delete previously suggested chars on the command line. (As you type, SCIM tries to guess final Asian chars and displays them.) However, these backspace chars are shown literally as ^H and not interpreted correctly. Example one-liner: perl -e 'print "Chinese: "; my $s = <STDIN>; print $s' When I enable SCIM Chinese or Japanese language input, as I type, e.g., nihao = ??, here is the result: ?^H?^H?^H?^H?^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H?? At the very end of this string, you can see "??" (nihao/hello). At a normal bash prompt, if I type nihao (with Chinese enabled), the results is perfect. This has something to do with interpretation of backspace chars (or control chars) during Perl's STDIN. The same thing happens when using command 'read' in Bash. Witness: read -p 'Chinese: ' s && echo $s

  • UIWebView autosize issue only on iOS 4.3

    - by troop231
    I am trying to figure out how to fix this bug that only occurs on iOS 4.3. When the application launches, it displays a PDF that is scaled to fit in the UIWebView. It behaves perfectly until you pinch to zoom on the document, and then rotate it, leaving behind a black area. If you don't pinch to zoom, it doesn't leave the black area. I don't understand why this is a iOS 4.3 only issue. Screenshot of the issue: I've been trying to solve this problem awhile now, and would greatly appreciate your help. Thank you. Screenshots of the .xib settings: The code I'm using is: .h: #import <UIKit/UIKit.h> @interface ViewController : UIViewController { UIWebView *webView; } @property (nonatomic) IBOutlet UIWebView *webView; @end .m: #import "ViewController.h" @interface ViewController () @end @implementation ViewController @synthesize webView; - (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { return YES; } else { return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); } } - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"]; NSURL *url = [NSURL fileURLWithPath:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [webView loadRequest:requestObj]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } @end

  • Set DetailsView as selected row of GridView

    - by Nix
    I am afraid this is a brain fart question. But I have searched around and have not been able to find the answer. I am creating a GridView/DetailsView page. I have a grid that displays a bunch of rows, when a row is selected it uses a DetailsView to allow for Insert/Update. My question is what is the best way to link these? I do not want to reach out to the web service again, all the data i need is in the selected grid view row. I basically have 2 separate data sources that share the same "DataObjectTypeName", the first data source retrieves the data, and the other to do the CRUD. What is the best way to transfer the Selected Grid View row to the Details View? Am I going to have to manualy handle the Insert/Update events and call the data source myself? <asp:GridView ID="gvDetails" runat="server" DataKeyNames="ID, Code" DataSourceID="odsSearchData" > <Columns> <asp:BoundField DataField="RowA" HeaderText="A" SortExpression="RowA" /> <asp:BoundField DataField="RowB" HeaderText="B" SortExpression="RowB" /> <asp:BoundField DataField="RowC" HeaderText="C" SortExpression="RowC" /> ....Code... <asp:DetailsView ID="dvDetails" runat="server" DataKeyNames="ID, Code" DataSourceID="odsCRUD" GridLines="None" DefaultMode="Edit" AutoGenerateRows="false" Visible="false" Width="100%"> <Fields> <asp:BoundField DataField="RowA" HeaderText="A" SortExpression="RowA" /> <asp:BoundField DataField="RowB" HeaderText="B" SortExpression="RowB" /> <asp:BoundField DataField="RowC" HeaderText="C" SortExpression="RowC" /> ...

  • "Ghost" values in PHP/Smarty.

    - by Kyle Sevenoaks
    I've been working on a site for a while changing the layout and skin of a webshop checkout process. I've noticed that if you go all the way through the process until the last page, then click the link to go back to the view products page, the delivery method price displays underneath the navigation buttons, until you refresh and it goes away again. I've downloaded both sourced from the browser (Chrome, but this bug applies to all browsers) and used a file difference tool to display the differences, the result being only: < error.html vs > normal.html 34c34 < <link href="gzip.php?file=167842c1496093fbcd391b41cf7b03da.css&time=1272272181" rel="Stylesheet" type="text/css"/> --- > <link href="gzip.php?file=167842c1496093fbcd391b41cf7b03da.css&time=1272272348" rel="Stylesheet" type="text/css"/> Which is just the way it zips up the CSS stylesheets. (afaik) Has anyone ever encountered such a problem, or anything similar? Normal: Error: I can't even hazard a guess as to what is causing this, at all. I've searched over Google for anything and come up with nothing. What could be causing this? The site in question is Euroworker.no. HTML @ Pastebin.

  • How do I use cookies to store users' recent site history(PHP)?

    - by ggfan
    I decided to make a recent view box that allows users to see what links they clicked on before. Whenever they click on a posting, the posting's id gets stored in a cookie and displays it in the recent view box. In my ad.php, I have a definerecentview function that stores the posting's id (so I can call it later when trying to get the posting's information such as title, price from the database) in a cookie. How do I create a cookie array for this? **EXAMPLE:** user clicks on ad.php?posting_id='200' //this is in the ad.php function definerecentview() { $posting_id=$_GET['posting_id']; //this adds 30 days to the current time $Month = 2592000 + time(); $i=1; if (isset($posting_id)){ //lost here for($i=1,$i< ???,$i++){ setcookie("recentviewitem[$i]", $posting_id, $Month); } } } function displayrecentviews() { echo "<div class='recentviews'>"; echo "Recent Views"; if (isset($_COOKIE['recentviewitem'])) { foreach ($_COOKIE['recentviewitem'] as $name => $value) { echo "$name : $value <br />\n"; //right now just shows the posting_id } } echo "</div>"; } How do I use a for loop or foreach loop to make it that whenever a user clicks on an ad, it makes an array in the cookie? So it would be like.. 1. clicks on ad.php?posting_id=200 --- setcookie("recentviewitem[1]",200,$month); 2. clicks on ad.php?posting_id=201 --- setcookie("recentviewitem[2]",201,$month); 3. clicks on ad.php?posting_id=202 --- setcookie("recentviewitem[3]",202,$month); Then in the displayrecentitem function, I just echo however many cookies were set? I'm just totally lost in creating a for loop that sets the cookies. any help would be appreciated

  • How do I format a Uri when binding an Image in Silverlight?

    - by Scott
    I haven't been able to find an answer to this. I have a database that has image paths in it ("images/myimage.jpg"). These images exist on my asp.net site which is also where I host the SL. I want to bind these images to my ListBox control so that the image displays. I have read that since I have a string value, "images/myimage.jpg", that I need to convert it to a BitMap image. I have done this: the xaml: <Image Source="{Binding ImageFile, Converter={StaticResource ImageConverter}}"/> the ImageConverter class: public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { try { Uri source= new Uri(value.ToString()); return new BitmapImage(source); } catch(Exception ex) { return new BitmapImage(); } } I get an error when creating the Uri, "The Format of the URI could not be determined". What am I doing wrong? If I create a Uri that looks like this: http://localhost:49723/images/myimage.jpg, it works just fine. Why doesn't just "images/myimage.jpg" work?

  • How do I get my Windows Forms application to use a custom main function and get access to the Applic

    - by burble
    Hi Folks I am trying to use a Main () function in a class to control the program flow in my vb .net Windows Forms application. I have added a splash screen component and a login screen, and customised my main sdi form. I have set the startup form to be my main function in the Application Page of the Project Designer, and everything seems to work fine(ish). However, I would like to use: Me.MinimumSplashScreenDisplayTime = 5000 to ensure that the splash screen is visible, but it is not recognised by the system unless I tick the Enable Application Framework check box on the Project Designer. If I do this, on startup the program ignores the login and splash screens and all my customisation and just displays a default Form1, even though I have also specified my splash screen in the AF dropdown list. Of course, there are alternative ways to delay a splash screen, such as putting the thread temporarily to sleep (which didn't seem to work), but I suspect that there are other things in the AF that I may want to use. Any suggestions on how I can get round this please, and get a sensible means of controlling program flow? Any thoughts on the best overall structure for organising program flow would also be helpful too. I am concerned both about going down a Microsoft or an alternative custom route that may cause me problems later, as the application becomes more complex. Thankses.

  • powershell missing member methods in array

    - by Andrew
    Hi Guys I have (yet another) powershell query. I have an array in powershell which i need to use the remove() and split commands on. Normally you set an array (or variable) and the above methods exist. On the below $csv2 array both methods are missing, i have checked using the get-member cmd. How can i go about using remove to get rid of lines with nan. Also how do i split the columns into two different variables. at the moment each element of the array displays one line, for each line i need to convert it into two variables, one for each column. timestamp Utilization --------- ----------- 1276505880 2.0763250000e+00 1276505890 1.7487730000e+00 1276505900 1.6906890000e+00 1276505910 1.7972880000e+00 1276505920 1.8141900000e+00 1276505930 nan 1276505940 nan 1276505950 0.0000000000e+00 $SystemStats = (Get-F5.iControl).SystemStatistics $report = "c:\snmp\data" + $gObj + ".csv" ### Allocate a new Query Object and add the inputs needed $Query = New-Object -TypeName iControl.SystemStatisticsPerformanceStatisticQuery $Query.object_name = $i $Query.start_time = $startTime $Query.end_time = 0 $Query.interval = $interval $Query.maximum_rows = 0 ### Make method call passing in an array of size one with the specified query $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data) $csv2 = convertFrom-CSV $csvdata $csv2

  • rendering a TextView in a Bitmap for an android widget

    - by foke
    I'm building a widget which displays some text. By widget I mean the kind which lies on the desktop. The problem is that I want to change text's font at runtime. There is several textview I would like, at runtime, to set the first as bold, the second blue and italic for example, etc. I came up with this : TextView tv = new TextView(context); tv.setText(stringToDisplay); tv.setTextColor(0xa00050ff); // example tv.setTextSize(30); // example Bitmap b = loadBitmapFromView(tv); updateViews.setImageViewBitmap(R.id.id_of_the_imageview, b); with private static Bitmap loadBitmapFromView(View v) { Bitmap b = Bitmap.createBitmap(v.getLayoutParams().width, v.getLayoutParams().height, Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height); v.draw(c); return b; } but it wont work (NullPointerException on first line of loadBitmap), until I replace v.getLayoutParams().width, v.getLayoutParams().height by fixed sizes like 250, 50 Bitmap b = Bitmap.createBitmap(250, 50, Bitmap.Config.ARGB_8888); // ... v.layout(0, 0, 250, 50); But that's not a good solution ... so I tried this : LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View row = li.inflate(R.layout.widget_text, null); TextView tv = (TextView) row.findViewById(R.id.id_of_the_textview); widget_text being a layout similar to the displayed one but with TextViews instead of ImageViews, in the hope to get some size information out of it .. but it's not working and I get this exception : 01-02 17:35:06.001: ERROR/AndroidRuntime(11025): Caused by: java.lang.IllegalArgumentException: width and height must be > 0 on the call to Bitmap.createBitmap() so, someone could point me in the right direction?

  • $_SERVER['HTTP_REFERER'] not working with Header

    - by EmmyS
    I have a site that allows public access to some pages, but requires a login for others. I have a link to the login from all pages, and what I'd like to do after a successful login is send the user back to the page they were on when they clicked the login link. I know the HTTP_REFERER can be spoofed, and sometimes stripped out by certain hosts and proxies, but since it's strictly within my own site, and only a convenience for users, I'm not too worried about it. I am curious about why it isn't working in conjunction with a redirect, though. I've set a visible field to contain the value of the http referer, and it displays correctly. So the page is getting the value of the referrer variable. But when I try this: $home_url = $_SERVER['HTTP_REFERER']; header('Location: ' . $home_url); it doesn't work. This, on the other hand, does: $home_url = 'http://' . $_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']).'/discussions.php'; header('Location: ' . $home_url); So I know the header location part works. Any idea why it doesn't want to work in conjunction with the http_referer variable? (Also, does it drive anyone else nuts that referer is spelled incorrectly? I keep mistyping it using the OED spelling, silly me...)

  • How do I setup model associations in an RSpec test?

    - by Eric M.
    I've pastied the specs I've written for the posts/show.html.erb view in an application I'm writing as a means to learn RSpec. I am still learning about mocks and stubbing. This question is specific to the "should list all related comments" spec. What I want is to test that the show view displays a post's comments. But what I'm not sure about is how to setup this test and then have the test iterate through with should contain('xyz') statements. Any hints? Other suggestions are also appreciated! Thanks. ---Edit Some more information. I have a named_scope applied to comments in my view (I know, I did this a bit backwards in this case), so @post.comments.approved_is(true). The code pastied responds with the error "undefined method `approved_is' for #", which makes sense since I told it stub comments and return a comment. I'm still not sure, however, how to chain the stubs so that @post.comments.approved_is(true) will return an array of comments.
