  • How do you get the pageYOffset of from the bottom of the window and not the top ( Javascript )?

    - by user782860
    I need to get the pageYOffset of the bottom of the viewable area, whether the user is zoomed in on the webpage or not, on Mobile Safari ( iPhone ). However pageYOffset returns the offset from the upper left corner of the window. Spec: "pageYOffset properties returns the pixels the current document has been scrolled from the upper left corner of the window" How do you get the page y offset from the bottom of the viewable area, (zoomed in or not) on the iPhone via Javascript?

  • How to get an error message out of my webpage

    - by Vaccano
    I have a web page that when I run it on a remote computer I get the message saying that remote errors cannot be viewed When I go to view it on my web server machine, I get a message saying: Internet Explorer cannot display the webpage • Most likely causes: • You are not connected to the Internet. • The website is encountering problems. • There might be a typing error in the address. What you can try: Check your Internet connection. Try visiting another website to make sure you are connected. Retype the address. Go back to the previous page. I can get to google fine, so it is not the internet connection.... But this message gives me nothing to work on. How can I get more info as to why my page is not working? I tried going to IIS Mananger and right clicking on the site and selecting browse. But my site is an HTTPS site so that does not work. Any ideas would be great.

  • Refetching a previously visited page

    - by user613665
    All, I am having a field day with page refetching. Any help or pointer will be greatly appreciated!! The behavior is a bit specific to mobile browser. Problem: I have two pages and created a shortcut link to pg#1 in the home page. Through a form submit button, user is taken from pg#1 to pg#2. All that is working fine. Now once I am on pg#2. I will leave the browser and click the shortcut later. The browser will stay on pg#2 and won't go to pg#1 even though the path in URLS is different between the two views. It is almost like Django decides that since I have already visited view#1, it doesn't need to fetch it again. This problem or behavior doesn't happen if I move the same code that handle the two views and the templates to a bare bone test project. Setup: I am using django-registration, context session. I am not using any HTML caching tag. I already have DEBUG turned on in my settings.py. Are there other ways that I can tell what the server is doing. Thanks in advance. pdxMobile Update: Here is the code snippets. def sendmsg(request): if request.method =='POST': messages.add_message(request, messages.INFO, "Hello world") return redirect ('rcvmsg') return render_to_response('sendMsg.html',RequestContext(request)) def rcvmsg(request): '''view that receives the msg.''' printMsg ='Didnt get a message' if messages: thisMsg = messages.get_messages(request) for rcvMsg in thisMsg: printMsg = rcvMsg return render_to_response('rcvMsg.html',{'print_msg':printMsg},RequestContext(request)) URL: url(r'^rcvMsg/','mydomain.mainApp.views.rcvmsg',name='rcvmsg'), (r'^sendMsg/code','mydomain.mainApp.views.sendmsg'),

  • Making interactive touch objects on Android

    - by Greenhouse_Gases
    I've never built a game before, and I've not programmed for Android before but am looking to do so over the summer by building a game. What type of object do I use for a shape that I want the user to be able to drag around the screen for instance using touch gestures? How do I tie together the MotionEvent, View and Graphics2D to make objects drawn on screen that can be interacted with? I imagine this will use ActionListeners / Handlers but I'm a bit confused at this stage... A simple breakdown of steps would be much appreciated. Thanks

  • How can I be a Guru? Is it possible? [closed]

    - by Kev
    Before 1999, I heard about computer. But, I don't know what it look like. TV? Maybe! Before 2001, I only saw it in book. It looks like a TV. Before 2005, I touched it in reality. It still looks like a TV + Black Box. In 2005, I entered university. I had a cource about Mathematica.I loved programming since then. In 2006, I owned a computer. I was coding C every day. if...else..., for..., while..., switch... entered my life. Since 2007, I have learned Data Structures, Algorithms...Then, C#, Java, Python, HTML/CSS/JavaScript, F#... A lot of languages. I'm still learning new lang. Unfortunately, I only know syntax! I'm always a novice(??)! I know some guru start programming at age of 8 or 12. I admire these gurus who are compiler writers, language designers, architecture designers, Linux hackers... Is it possible to become a guru like me. If possible, how? what should I do now? Any advice? Thank you very much.

  • Developing for Windows 6.5

    - by j-t-s
    Hi All I have just got a new company mobile and would like to begin developing apps for the HTC HD2 Mobile Phone. However, when I downloaded Microsoft Windows Phone Developer Tools, it pretty much said right at the end of installation that "Setup could not install correctly", and I clicked on "more", and it said "Silverlight 4.0 could not install correctly". So, the fact that Windows Phone Dev Tools couldn't install completely was because of this Silverlight 4 that couldn't install! Has anyone had the same problems, if so, how did you resolve this issue (if you did)? And... Is there another way to develop applications for mobile phones running the Windows Operating System other than XNA and Windows Dev Tools? Even better... Could it be done simply using the current Visual Studio Express Edition I already have? Thanks All

  • Need guidance for my first Android application: how many activities should I use?

    - by jul
    Hi, I'm starting Android doing an application for searching restaurants, and some guidance would be welcome! On the first screen I'd like to have a search field with a submit button (I get the data from a web service), and below a list with the results of the search. When clicking on one of the items of the list it will show a screen with the restaurant details as well as a map showing its location. My questions are: Can I do everything in one single activity or should I do an activity for the search, one for the result list, one for the restaurant description, and another for the map? Would doing one single activity make the application more responsive? How can I use a list and a map within a normal activity (without ListActivity and MapActivity)? Any help, pointer, example application or sample code is very appreciated! Thank you Jul

  • Include a repetitive chunk of html with PHP?

    - by user146780
    I basically have a div on my Web Site that always has the same stuff. However, this div is not present on all pages which is why I won't use the dynamic web template. I was wondering if it was possible for PHP to get the code from a document on the server and put in into the div? Ex: div id="section... then my text file contains (p) hello (p) basically I want PHP to put it into the div when the user sees it. If theres a smarter way of acheiving this I'd be open to it aswell. Thanks

  • XNA: What is the point of Unload()?

    - by Rosarch
    XNA games have an Unload() method, where content is supposed to be unloaded. But what is the point of this? If all the content is being unloaded, then the game must be exiting, in which case everything would be garbage collected anyway, right?

  • Game network physics collision

    - by Jonas Byström
    How to simulating two client-controlled vehicles colliding (sensibly) in a typical client/server setup for a network game? I did read this eminent blog post on how to do distributed network physics in general (without traditional client prediction), but this question is specifically on how to handle collisions of owned objects. Example Say client A is 20 ms ahead of server, client B 300 ms ahead of server (counting both latency and maximum jitter). This means that when the two vehicles collide, both clients will see the other as 320 ms behind - in the opposite direction of the velocity of the other vehicle. Head-to-head on a Swedish highway means a difference of 16 meters/17.5 yards! What not to try It is virtually impossible to extrapolate the positions, since I also have very complex vehicles with joints and bodies all over, which in turn have linear and angular positions, velocities and accelerations, not to mention states from user input.

  • PHP: What's the best way to check equality of $_SERVER['HTTP_REFERER'] ?

    - by Hank
    I have a PHP script that checks the HTTP Referer. if ($_SERVER['HTTP_REFERER'] == 'http://www.example.com/') {...} However, this seems inherintly unsafe ... because what happens if the user goes to 'http://example.com/' or 'http://www.ExaMple.com' (both of which don't match the equality test). Question: what's a better equality test to ensure that the HTTP Referer is coming from 'example.com' ?

  • passing a float as a pointer to a matrix

    - by numerical25
    Honestly, I couldnt think of a better title for this issue because I am having 2 problems and I don't know the cause. The first problem I have is this //global declaration float g_posX = 0.0f; ............. //if keydown happens g_posX += 0.03f; &m_mtxView._41 = g_posX; I get this error cannot convert from 'float' to 'float *' So I assume that the matrix only accepts pointers. So i change the varible to this.... //global declaration float *g_posX = 0.0f; ............. //if keydown happens g_posX += 0.03f; &m_mtxView._41 = &g_posX; and I get this error cannot convert from 'float' to 'float *' which is pretty much saying that I can not declare g_posX as a pointer. honestly, I don't know what to do.
