  • How can a web developer learn to develop for the iPhone?

    - by Jared Christensen
    I'm a web developer and I'm getting envious of all the cool iPhone apps. I know nothing about C or what ever language they use to make iPhone apps. I really have no idea where to start. What do I need to do? Should I take a class, buy a book? I have a pretty good grasp on programing, I do tons of HTML, CSS and Javascript development and some PHP and Action Scripting. I'm not very good with Object Oriented Programing but I think I could pick it up if I used it more. I love video tutorials like lynda.com or net.tutsplus.com. I learn best buy jumping in and getting my hands dirty.

  • How to access Session values from layers beneath the web application layer.

    - by Matthew Vines
    We have many instances in our application where we would like to be able to access things like the currently logged in user id in our business domain and data access layer. On log we push this information to the session, so all of our front end code has access to it fairly easily of course. However, we are having huge issues getting at the data in lower layers of our application. We just can't seem to find a way to store a value in the business domain that has global scope just for the user (static classes and properties are of course shared by the application domain, which means all users in the session share just one copy of the object). We have considered passing in the session to our business classes, but then our domain is very tightly coupled to our web application. We want to keep the prospect of a winforms version of the application possible going forward. I find it hard to believe we are the first people to have this sort of issue. How are you handling this problem in your applications?

  • Is is possible to parse a web page from the client side for a large number of words and if so, how?

    - by Technoh
    I have a list of keywords, about 25,000 of them. I would like people who add a certain < script tag on their web page to have these keywords transformed into links. What would be the best way to go and achieve this? I have tried the simple javascript approach (an array with lots of elements and regexping/replacing each) and it obviously slows down the browser. I could always process the content server-side if there was a way, from the client, to send the page's content to a cross-domain server script (I'm partial to PHP but it could be anything) but I don't know of any way to do this. Any other working solution is also welcome.

  • How to retrieve files/documents that are not found on the web server machine.

    - by jhorton
    I am trying to create an export feature for a user to be able to download documents into a zip file. I have the feature working when the files are located on my local and I can use an absolute path on my local. But after talking to the infrastructure team, I found out that the documents are not stored on the same machine as the web server but located at a server farm located off site. I can query the database which gives me a file path. But the path is more of a relative path. So can anyone help me understand how to use FileInfo with getting files from another machine. I believe the infrastructure team said there is a virtual drive set up to the outside server. Am I able to use a virtual path some how? Thanks.

  • How to move to a location in a web browser component?

    - by Mostafa Mahdieh
    I have a .NET windows form page and a WebBrowser component inside. I load a page inside the web browser using the Navigate method as in: webBrowser1.Navigate("http://www.stackoverflow.com"); The pages length is longer than the browsers height, so the vertical scroll bar appears. Now I want to move the scrollbar down to a specific position. More specifically I want to search for a specific peace of text inside the page, and scroll to that position. This behavior is implemented in the built-in "Find" function of the browser, but I can't figure out how to call the Find function from within my code, without the Find window appearing. Although I don't want the Find window to appear, if the text matches are highlighted it is welcome.

  • How do you pull the URL for an ASP.NET web reference from a configuration file in Visual Studio 2008

    - by Ian Robinson
    I have a web reference for our report server embedded in our application. The server that the reports live on could change though, and I'd like to be able to change it "on the fly" if necessary. I know I've done this before, but can't seem to remember how. Thanks for your help. update - I've manually driven around this for the time being. It's not a big deal to set the URL in the code, but I'd like to figure out what the "proper" way of doing this in VS 2008 is. Could anyone provide any further insights? Thanks!

  • How to avoid web server traffic peak resulting from iOS Newsstand app receiving a remote notification?

    - by thomers
    I'm developing an iOS Newsstand app. If it is suspended or not running and connected to a WLAN, Newsstand apps can be triggered by a Push remote notification to download the latest issue (in our case around 100MB) in the background. I'm using Urban Airship for the delivery of the Push broadcast. I'm now worrying about many many iOS devices hitting the web server for one big download more or less at the same time, because I expect the majority of the devices will receive the notification in a very short timeframe. Instead of broadcasts to all devices, should I rather send individual notifications to batches of small groups of devices, spreading them out over a longer period of time? And/or would a CDN like Amazon Cloudfront solve that issue easier/anyway?

  • Web based API that can tell me if a number is a landline or cell phone?

    - by MikeN
    My application sends SMS messages to people, but the numbers entered in as their cell phone are sometimes land lines (this is user error or the user not really knowing if the contact number they have is a cell phone or landline.) I found a few websites that can tell me if a number is a landline or cell phone, but they do not offer programatic API's. Is anyone aware of a way a web application can figure out if a number can receive SMS messages? I guess a test SMS message is one way, but my current SMS gateway fails hard when it gets a landline number and doesn't tell me the landline number it tried to send the SMS to. I'll follow this up with my carrier, but I would love an easy way to let the user entering phone numbers in if they are a landline or cell number. Update: There are ways to figure this out. Take a look at http://www.phonevalidator.com, they can query a phone number and figure out if it is a landline or cell phone.

  • How to embed a web browser control in a cross-platform application?

    - by Gil
    hi, I need to write quickly this application: a simple window that wraps a web browser control, that runs html pages. The Browser UI (e.g. Navigation buttons) should be suppressed. As a .net developer, I would embed the WebBrowser OCX in a Windows Form. But this has to run on Mac as well!! I found the following cross-platform candidates. Which one would you choose (in terms of simplicity, stableness, community support, etc.): 1) wxWidgets (www.kirix.com/labs/wxwebconnect.html) 2) QT: www.youtube.com/watch?v=Ee8eRwjbcFk&feature=related 3) MONO: www.mono-project.com/WebBrowser Thanks!

  • How do I secure password parameters in RESTful web service URIs?

    - by adam
    i'm a newbie to server-side programming, so please forgive me if this gets messy. i've been contracted to create a web service to allow authenticated users to access a database. users have to enter a login and password. been reading and reading about REST vs SOAP, and i thought i'd settled on a RESTful design when i came across this statement: "Data that needs to be secure should not be sent as parameters in URIs." this seems like a major demerit against a RESTful approach. i'm aware that with https the password would be encrypted to prevent man-in-the-middle interception, but that leaves the server logs and client history as possible exposure points. is there a RESTful solution out there for this problem, or do i need to go SOAPy? any advice appreciated.

  • Why are web developers so keen to use lists ?

    - by Bob
    I've been developing for a while and often develop sites using menu tabs. And I can't figure out why so many web developers like using lists < ul < li etc rather than just using plain old divs. I can make menus in divs which are simple and work perfectly in every browser. With lists, I'm usually trying to hack it one way or another to get it work properly. So my question is simple : why should I use lists to create my menus instead of divs ?

  • Using .htaccess to rewrite dynamic subdomains

    - by brokekidweb
    I'm currently using .htaccess to rewrite on my website to create dynamic subdomains. I also use it to remove the .php extension on all pages. However, once inside the subdomain, it tries to redirect again. For example, if you went to https://admin.example.com/test, it would actually be accessing https://example.com/clients/admin/test.php. I keeping getting various 404 errors using the following .htaccess file: Options +MultiViews Options +FollowSymLinks RewriteEngine On RewriteRule ^subdomains/(.*)/(.*) http://$1.example.com/$2 [r=301,nc] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^([^\.]+)$ $1.php [NC,L] RewriteCond %{HTTP_HOST} !^(www\.)?example\.com$ [NC] RewriteCond %{HTTP_HOST} ^(www\.)?([^\.]+)\.example\.com$ [NC] RewriteCond %{DOCUMENT_ROOT}/%2%{REQUEST_URI}/ -d RewriteRule [^/]$ %{REQUEST_URI}/ [R=301,L] RewriteCond %{ENV:REDIRECT_STATUS} ^$ RewriteCond %{HTTP_HOST} !^(www\.)?example\.com$ [NC] RewriteCond %{HTTP_HOST} ^(www\.)?([^\.]+)\.example\.com$ [NC] RewriteRule ^(.*)$ clients/%2/$1 [QSA,L] How can I keep this from redirecting to https://admin.example.com/clients/admin/test.php?

  • Looking for a clear and concise web page explaining why lower bits of random numbers are usually not

    - by Hamish Grubijan
    I am putting together an internal "every developer should know" wiki page. I saw many discussions regarding rand() % N, but not a single web page that explains it all. For instance, I am curious if this problem is only C- and Linux-specific, or if it also applies to Windows, C++,. Java, .Net, Python, Perl. Please help me get to the bottom of this. Also, just how non-random do the numbers get? Thank you!

  • VIsual Studio 2010 Web Performance Test / Load tests / Coded UI Tests. ANYONE REALLY USE THESE?

    - by punkouter
    I can find some articles on how to use them but I can't seem to find anywhere peoples impression of them using them in real projects. I have been trying to figure out how to use them and Ive had alot of problems.. Can someone out there who uses these tools on the job give me thier impression? Are there better alternate tools available? Using these really just a waste of time ? With Coded UI Tests I see how they are good for basic javascript checking but its so basic of a example I don't think it is worth it. With web tests I like how they work but when I activate code coverage/ASP.NET profiling it doesnt work half the time.

  • How to Prevent an Applet from Unloading across web pages?

    - by Francis Shanahan
    I have a large applet that takes some 40 seconds to initialize (cabs are cached so ignore download time for this question). The issue is, if the user goes to Page A which launches the applet (single window) and then navigates to page B, the applet is unloaded. If the user goes back to Page A, they incur the 40 seconds init time once again. I'd like to be able to launch the applet, incurring the 40 seconds init time once and only once. The applet needs to reside inside a single browser window (the same window as my web application). In other words, I cannot launch the applet in a popup. Does anyone have any creative ideas around how to prevent the applet unloading?
