  • fixed vertical positioning of css within an iframe

    - by Jake Rider
    I am trying to get my bottom header to stick to the bottom of the screen inside of my iframe application and have it always appear in view for the user even when the page is scrolling. I have no control over the outer iframe as it is on a different domain. The header itself must be inside of the iframe as I have no control outside the iframe. The iframe always expands to the height of its contents so that it has no scrollbars, but the bar still has to be visible in the viewport at all times.

  • UITableView becomes invisible after changing data in it

    - by Alexander Shemshurenko
    Hi I have application with TabBar that control several views. In one view i control connection to different servers.Each server provides different set of items. I display these items in UITableView on other view. I create table view like this UITableView * aTableView = [[UITableView alloc] initWithFrame:CGRectMake(X,Y,Width,Height) style:UITableViewStyleGrouped]; [[self view] addSubview:aTableView]; aTableView.da taSource = self; The problem is that Table view displayed ok first time , but if i go back to view number one and change server(changing list of items that should be displayed in table view), table view becomes invisible for some reason. If i tap on the screen in place where it should be, its becomes visible again. Ive tried to call to reloadData and setNeedDisplay in viewWillAppear of the UIViewController that hosts this table view, but without success. Any advice? Thanks

  • How to draw a transparent stroke (or anyway clear part of an image) on the iPhone

    - by devguy
    I have a small app that allows the user to draw on the screen with the finger. Yes, nothing original, but it's part of something larger :) I have a UIImageView where the user draws, by creating a CGContextRef and the various CG draw functions. I primarily draw strokes/lines with the function CGContextAddLineToPoint Now the problem is this: the user can draw lines of various colors. I want to give him the ability to use a "rubber" tool to delete some part of the image drawn so far, with the finger. I initially did this by using a white color for the stroke (set with the CGContextSetRGBStrokeColor function) but it did't work out...because I discovered later that the UIImage on the UIImageView was actually with transparent background, not white...so I would end up with a transparent image with white lines on it! Is there anyway to set a "transparent" stroke color...or is there any other way to clear the content of the CGContextRef under the user's finger, when he moves it? Thanks

  • WPF Application - Role Management Recommendations

    - by David Ward
    I have a WPF application with a WCF service layer and a SQL database. I now want to restrict elements of the application so that certain functions are only available to those users with a particular role. For example, you will only be able to navigate to the settings screen if you are an administrator. I would like a user to be a member of 1 or more authorisation groups and each authorisation group to have 1 or more roles associated. A long time ago I used AzMan (Authorisation Manager) to do a similar thing. Does anyone think that there are better approaches? Is AzMan "old news"? Alternatives? Thanks.

  • Question about layout in java.

    - by extro
    I have two panels main_panel and child_panel. I have set layout for main_panel by using "main_panel.setLayout(flowlayout)" and added child_panel in main_panel by using "main_panel.add(child_panel)". This child_panel gets added to main_panel but its position is at the cross-section of horizontal midpoint and top vertical section of screen. But I want child_panel to be at the top left corner, something I could have done by using "child_panel.setlocation(a,b)" method, if I have set the Layout of main_panel as NULL. I have used flowlayout here because I want components in the JPanel to keep adjusting with the size of JFrame. So question is, can I add child_panel to main_panel at the exact location I want, even if I set the Layout of main_panel as not NULL.

  • Android how to make ImageView with a minWidth have a border?

    - by Kman
    I want to diplay an image so that it takes up a minmum width of the screen and should scale in its aspect ratio (the image width might be smaller or larger than the minimun width) I also want to have a fixed size border around this image. This is my xml section for it: <ImageView android:id="@+id/detailed_view_boxArt" android:layout_width="wrap_content" android:layout_height="wrap_content" android:minWidth="150dp" android:layout_alignParentLeft="true" android:layout_below="@id/detailed_view_heading" android:padding="10dp" android:layout_marginLeft="5dp" android:scaleType="centerInside" android:background="#000"/> This however does not produce what I want...the problem is that it does not scale the image horizontally far enough (ie. the 10px padding that I have seems a lot more on the right and left) How would I produce the result that I want?

  • Free (as in beer) Reverse Image Search API/Library/Service

    - by Bauer
    TinEye provides a great way to "reverse" search by image (i.e. upload/transload an image and have multiple possible sources of that image returned as results.) Since screen-scraping is messy and unreliable, I'm looking for a free API/library/web-service that could offer the same (or similar) reverse-image search function. At present, TinEye offers a commercial API, but since I'll only be using the service for small personal projects, it's hard to justify the cost of the service (the lowest being 1,000 searches for $70 USD). Is anyone aware of such a free service? Or is there a simpler way to approach this (programmatic solution; any language)? I understand that this is a tall order, and submitting the question is really only a last resort in the hope that there is some solution. Example image search is 99designs' StackOverflow logo competition entry by wolv

  • JSF - Session Bean restart on logout and login

    - by Ben
    Hi, I have a web application with a backing bean which has the context of the current logged in user. It is implemented on JSF. When the user logs out he is forwarded to a login screen (in another JSP page). I would like the current session to be erased when that happens and a new one to be created the next time the user logs in and enters the application. My question is - how do you delete a session? (I guess the new session will be created automatically the next time the user enters the link) This is kinda newb i guess, but I couldn't find a solution for this. Thanks for the Help!

  • $_GET loading content before head tag instead of in specified div.

    - by s32ialx
    NOT EDITING BELOW BUT THANKS TO SOME REALLY NICE PEOPLE I CAN'T POST AN IMAGE ANYMORE BECAUSE I HAD a 15 Rep but NOW ONLY A 5 becuase my question wasn't what they wanted help with they gave me a neg rep. The problem is that the content loads it displays UNDER the div i placed #CONTENT# inside so the styles are being ignored and it's posting #CONTENT# outside the divs at positions 0,0 any suggestions? Found out whats happening by using "View Source" seems that it's putting all of the #CONTENT#, content that's being loaded in front of the <head> tag. Like this <doctype...> <div class="home"> \ blah blah #CONTENT# bot being loaded in correct specified area </div> / <head> <script src=""></script> </head> <body> <div class="header"></div> <div class="contents"> #CONTENT# < where content SHOULD load </div> <div class="footer"></div> </body> so anyone got a fix? OK so a better description I'll add relevant screen-shots Whats happening is /* file.class.php */ <?php $file = new file(); class file{ var $path = "templates/clean"; var $ext = "tpl"; function loadfile($filename){ return file_get_contents($this->path . "/" . $filename . "." . $this->ext); } function setcontent($content,$newcontent,$vartoreplace='#CONTENT#'){ $val = str_replace($vartoreplace,$newcontent,$content); return $val; } function p($content) { $v = $content; $v = str_replace('#CONTENT#','',$v); print $v; } } if(!isset($_GET['page'])){ // if not, lets load our index page(you can change home.php to whatever you want: include("main.txt"); // else $_GET['page'] was set so lets do stuff: } else { // lets first check if the file exists: if(file_exists($_GET['page'].'.txt')){ // and lets include that then: include($_GET['page'].'.txt'); // sorry mate, could not find it: } else { echo 'Sorry, could not find <strong>' . $_GET['page'] .'.txt</strong>'; } } ?> is calling for a file_get_contents at the bottom which I use in /* index.php */ <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <?php include('classes/file.class.php'); // load the templates $header = $file->loadfile('header'); $body = $file->loadfile('body'); $footer = $file->loadfile('footer'); // fill body.tpl #CONTENT# slot with $content $body = $file->setcontent($body, $content); // cleanup and output the full page $file->p($header . $body . $footer); ?> and loads into /* body.tpl */ <div id="bodys"> <div id="bodt"></div> <div id="bodm"> <div id="contents"> #CONTENT# </div> </div> <div id="bodb"></div> </div> but the issue is as follows the $content loads properly img tags etc <h2> tags etc but CSS styling is TOTALY ignored for position width z-index etc. and as follows here's the screen-shot My Firefox Showing The Problem In Action REPOSTED DUE TO PEOPLE NOT HELPING AND JUST BEING ARROGANT AND GIVING NEGATIVE VOTES and not even saying a word.

  • matplotlib.pyplot, preserve aspect ratio of the plot

    - by Headcrab
    Assuming we have a polygon coordinates as polygon = [(x1, y1), (x2, y2), ...], the following code displays the polygon: import matplotlib.pyplot as plt plt.fill(*zip(*polygon)) plt.show() By default it is trying to adjust the aspect ratio so that the polygon (or whatever other diagram) fits inside the window, and automatically changing it so that it fits even after resizing. Which is great in many cases, except when you are trying to estimate visually if the image is distorted. How to fix the aspect ratio to be strictly 1:1? (Not sure if "aspect ratio" is the right term here, so in case it is not - I need both X and Y axes to have 1:1 scale, so that (0, 1) on both X and Y takes an exact same amount of screen space. And I need to keep it 1:1 no matter how I resize the window.)

  • How to inject a "runtime" dependency like a logged in user which is not available at application boot time?

    - by Fabian
    I'm just not getting this: I use Gin in my java GWT app to do DI. The login screen is integrated into the full application window. After the user has logged in I want to inject the user object into other classes like GUI Presenters which I create, so I have some sort of runtime dependency I believe. How do i do that? One solution I can think of is sth like: class Presenter { @Inject Presenter(LoggedInUserFactory userFactory) { User user = userFactory.getLoggedInUser(); } } class LoggedInUserFactoryImpl { public static User user; User getLoggedInUser() { return user; } } So, when the user is successfully logged in and I have the object i set the static property in LoggedInUserFactory, but this will only work if the Presenter is created after the user has logged in which is not the case. Or should I use a global static registry? I just don't like the idea of having static dependencies in my classes. Any input is greatly appreciated.

  • What causes a WPF ListCollectionView that uses custom sorting to re-sort its items?

    - by Drew Noakes
    Consider this code (type names genericised for the purposes of example): // Bound to ListBox.ItemsSource _items = new ObservableCollection<Item>(); // ...Items are added here ... // Specify custom IComparer for this collection view _itemsView = CollectionViewSource.GetDefaultView(_items) ((ListCollectionView)_itemsView).CustomSort = new ItemComparer(); When I set CustomSort, the collection is sorted as I expect. However I require the data to re-sort itself at runtime in response to the changing of the properties on Item. The Item class derives from INotifyPropertyChanged and I know that the property fires correctly as my data template updates the values on screen, only the sorting logic is not being called. I have also tried raising INotifyPropertyChanged.PropertyChanged passing an empty string, to see if a generic notification would cause the sorting to be initiated. No bananas. EDIT In response to Kent's suggestion I thought I'd point out that sorting the items using this has the same result, namely that the collection sorts once but does not re-sort as the data changes: _itemsView.SortDescriptions.Add( new SortDescription("PropertyName", ListSortDirection.Ascending));

  • Visual Studio massive renaming of controls in WPF project

    - by Mark
    I have a scene in my WPF project with about 2000 different user controls: <local:MyControlType x:name="aaka4sn9f" /> <local:MyControlType x:name="aaks22nf_1" /> <local:MyControlType x:name="aa66s2f_2" /> and so on down the screen... Is there a way to rename all of these controls using Visual Studio (and possibly a regex) to be: <local:MyControlType x:name="myControl1" /> <local:MyControlType x:name="myControl2" /> <local:MyControlType x:name="myControl3" /> ?? Thanks a lot!

  • Headless HTML rendering to image on CentOS 5.4

    - by Jim Tough
    Hello, I have a project requirement to render HTML and capture the rendered image as a file on a headless CentOS 5.4 server. My specific requirements are: 1) Input will be a URL to the page to render, output will be an image file containing the rendered image of the page 2) CSS must be supported by the renderer up to CSS level-1 3) Static images in the page must be displayed properly in the rendered image, including any transparent color in .GIF files 4) Must be able to run on a headless CentOS 5.4 server. 5) Solution must not depend on any product or component that is not free for commercial use I do not need to do anything with the page other than get the screen capture and save it to an image. The hard part seems to be doing this in a headless environment. Some of the solutions that I've seen discussed need a display in order to work. Any suggestions? Thanks in advance, Jim

  • Anyone run recurring payments in their website? Preferably; Paypal API

    - by James
    I'm wrapping up my startup and will need to implement Paypal API into my sign up page. Does anyone use recurring payments via Paypal API integrated into their billing? Better yet, guide me to a trustable developer with experience or will I have to use Elance? I need it to go to a welcome/get started screen in their logged in account once they hit the 'create account' button after filling out billing info. I was also wondering, can you leave the CSC (3 digit security code) field out with integration, because it makes things very hard for recurring payments. I'd like to stick with Paypal, as I have been very satisfied with them for a few years now; I already checked out Chargify, authorize.net, etc. I'd love to see someone with something like this set up already to take a look at and ask a few questions.

  • Python command line UI

    - by hdx
    Hey guys/gals I'm writing a python script that fixes some duplicate issues on my database. I would like to display some progress status to the users, currently I just print it like this: print "Merged " + str(idx) + " out of " + str(totalCount); The problem is that it prints that in a new line for every record and that does not look so good :) I'd like to either always print the string above on the same line on the screen or use some smart widget that displays it in some sort of progress bar. I intent to run this on the command line, any suggestions will be much appreciated.

  • Java: I can't interact with my JFrame

    - by Wooooo
    Hi, I have a java application (1.4.2) that uses 2 JFrames. The first is Modal=true and appears on top of the second JFrame. The first JFrame allows the user to "open" a file. Once the file is ready to be displayed, the JFrame is set to setModal=false, and this.dispose() 'd of. This leaves only the second JFrame on the screen. However, I can't interact with it. The code does not throw any errors and appears to run perfectly fine. BUT I can;t interact with the second JFrame. The ONLY way to exit the JFrame is to hit the stop button on my development envirnment. I literally cannot stop the JFrame by clicking the close button, because I can't even interact with that portion of the JFrame. Any thoughts?

  • CSS for mobile sometimes reverts back to original

    - by Jessie
    So most of the time my stylesheets appear properly. The standard/original one always works flawlessly, however it seems sometimes the mobile one is disregarded when looked at from a mobile device I have them designated as follows: <link runat="server" href="CustomStyleSheets/Menu.css" rel="stylesheet" type="text/css" /> <link href="CustomStyleSheets/mobile.css" rel="stylesheet" type="text/css" media="only screen and (max-device-width: 799px)" /> I'm using a Droid X to view the page, in portrait mode, so the device width shouldn't be exceeding the max-width specified above, but sometimes, randomly, it still reverts back to the original css page. Any way to keep it from doing so?

  • Why does A* path finding sometimes go in straight lines and sometimes diagonals? (Java)

    - by Relequestual
    I'm in the process of developing a simple 2d grid based sim game, and have fully functional path finding. I used the answer found in my previous question as my basis for implementing A* path finding. (http://stackoverflow.com/questions/735523/pathfinding-2d-java-game). To show you really what I'm asking, I need to show you this video screen capture that I made. I was just testing to see how the person would move to a location and back again, and this was the result... http://www.screenjelly.com/watch/Bd7d7pObyFo Different choice of path depending on the direction, an unexpected result. Any ideas?

  • Play Video on Safari iTouch

    - by dave cohen
    I have a web site that opens iframe for video on page, page uses ajax to pull in videos from selected menu. As expected and understood, on iTouch after selecting video it shows a play button, which brings up video in another screen. However, when the video completes, it returns browser to page prior to one where video was played from. Sequence: - open Page1 - go to Page2 which offers videos to play, in iframe - play video - video completes, returns to Page1, not Page2!! Only happens on iTouch, so must be issue with how control is returned on video completion. Any suggestions? If this is not a known problem, I can work up example (currently, need account on site). Thanks Dave

  • Paging in ActiveRecord

    - by Alex
    Does CastleProject ActiveRecord support paging? I need to load only data which is now seen on the screen. If I use [HasMany], it will be loaded as a whole either immediately or at the first call (if lazy attribute is true). However I only need something like first 100 records (then maybe 100 next records). Another question is how to load only 100 items. If the collection is too big, memory can reach its limit if we constantly load more and more items.

  • How to effectively draw on desktop in C#?

    - by Lazlo
    I want to draw directly on the desktop in C#. From searching a bit, I ended up using a Graphics object from the Desktop HDC (null). Then, I painted normally using this Graphics object. The problem is that my shapes get lost when any part of the screen is redrawn. I tried a While loop, but it actually ends up drawing as fast as the application can, which is not the update rate of the desktop. Normally, I would need to put my drawing code in a "OnPaint" event, but such thing does not exist for the desktop. How would I do it? Example code: http://stackoverflow.com/questions/1536141/how-to-draw-directly-on-the-windows-desktop-c

  • Best approach to show big amount of "grid" data

    - by Jorge Ramírez
    Hello all. I am building an application for Android (1.5) that, after quering a webservice, shows to the user a big amount of data that should be displayed in a "grid" or "table" style. I must show a result of about 7 columns and 50 rows (for example a customer list with names, adresses, telephone number, sales amount last year and so). Obviously, the 7 columns will not fix in the screen and I would like the user would be able to scroll up/down and LEFT/RIGHT (important because of the number of columns) to explore the grid results. cell selection level is NOT necessary, as much I would need row selection level. What is the best approach to get this interface element? Listview / GridView / TableLayout? Thanks
