I know very little about web service but I assumed it would be the solution I was looking for. Basically I made an application in VB that I want to be ubiquitous for a lack of a better word. I need it to receive requests from multiple users and respond all at once. I was told "technically if you write a webservice you can provide as many results back to users as are connected."
Maybe there is another solution for me that will give me the results I want.
Here is an example of what I'm trying to do.
Lets say I make an application in VB that does math.
I now make a website. My website allows for a person to input 1 + 1
they click submit and my website then connects to my VB application running on my server
listening for a request. It accepts the request from my website, and then it solves the math problem and returns the answer back to the website "1 + 1 = 2"
That is only an example of the type of thing I need. My problem is that I can't have multiple people visiting my website all connecting to that same application running on my server so somehow I need the application to be where it can be accessed by multiple users. I was told a web service would be the answer but if there is another solution I'd like to know.
If the only solution is a web service, then how can I manage to either convert the VB app to a web service? Can I have to convert the app to asp.net or some other language? Is there an easier option?
Without knowing more about what you're actually doing, I might suggest that building an ASP.NET project around your existing VB code might be a good approach. It's going to be awkward to build any kind of "web service" around an existing (presumably GUI) application, so rebuilding your code inside ASP.NET would be the way to go.
How about doing it the push notification way.

You can inform users of your application via a push notification

I am trying to develop a cross platform app that uses a C# WCF web service. I have searched the web extensively but can't find anyone who has asked this question or posted a "how to" for this type of work flow.
For purposes of the question, let's focus on iPhone <--> Web Service interactions.
My app needs to do the following workflow:
iPhone#1 sends data to web service.
Web service pulls data from iPhone#2.
Web service does some calculations based on data from iPhone#1 and iPhone#2.
Web service sends results to iPhone#1 and iPhone#2.
iPhone#1 and iPhone#2 display results to users.
Steps 1, 3, and 5 are easy but how can I perform #2 and #4 above (requesting data from phone and sending data to phone)?
I don't necessarily need code samples, just a push in the right direction. Any help is much appreciated.
Thanks,
JVC
I was able to figure this out a while back and figured I would mention the solution in case anyone else runs across this.
In the most general sense, situations like this require the use of push notifications since they can be used to display a push notification on the device, or to send data packages to the phone for use in the app.
I ended up using Google's Cloud Messaging Service. It was very easy to implement and works like a champ.
Here is a link to the site with all of the proper documentation and guides: https://developers.google.com/cloud-messaging/
I've been racking my brain for a couple of days now on how to approach a new requirement.
I have two websites. The first one lets the user fill out an application. The second website is an internal website use to manage the users applications. I need to develop a "web service" that sends the application data from website 1 to website 2. I have never done a web service before and I'm a bit confused on where to start. I've been reading various examples online but they all seem to be just a starting point for building a webservice... no specific examples.
So for posting the data website 1, what would my controller method look like? What would and example of that look like? Is there some form of redirect in the method that points to website 2?
Thanks ahead of time for your assistance. :)
I want to create an application in which i want a login logout authentication from the database file that can be handled by web services. This application should always need to be connected with the internet and after login i need to upload images and also give there views about the image and i am not getting any idea how start work on that can anyone help me.... I want to use this application some sort similar like facebook.
There is also a problem that which type of application i create native or web or else. Please help me to start this application.....
Try setting up a server that can handle the requests from your app. Your app can then request content or upload content to the server using NSURLRequest. For further reading refer http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/URLLoadingSystem/Concepts/URLOverview.html
I think you are asking the wrong question. What web development language do you know to help you accomplish this? There are many different ways to go, like open source as opposed to paid, which services best handle your specific needs, like Ruby or PHP, which RDBMS to use, etc. If you don't know any programming, then it is going to be a long road. Your first step should be taking what you already know and branching from there, learning what you need to know. In your case, you'll need to learn server side scripting, connect it with a database, how to set up a server to put it all in, as well as client side development like javascript to go with the html.
I'm creating an iPhone Game where I want the user to get a unique numeric code when they first launch the app, that way when a friend of that user opens it, he/she can input that code and both users can get rewarded. I haven't encountered any issues regarding that, however what I want to do is make it to where the app registers the code given to every user and saves it to a website of some sort. That way when the other user enters the code, it will load the data from that website and check if it's registered. How would I manage to save the data onto a website? and also What free website could I use for this without having a character limit on the body page?
-Thanks in advance
Your thinking is correct, in that you need to save your data somewhere online, but you don't really "save data onto a website" in the way that you're describing. "Free Website" services usually serve a different purpose entirely - that of serving up public html pages. Sure, they can take the form of a CMS (like wordpress.com or tumblr accounts), but using that as an interface for storing your application's data is not something they're typically designed to do.
For something like this, where you have a public iPhone app that requires secure access to custom strings, you really want to have control over your own web server (different than a domain name, btw), and interface with a database on that server. This will come at a cost, and will involve more code than you're likely to find someone to write for you on here. Sorry to say it, but hey if someone wants to prove me wrong I'd love to see it.
Because all you need to store & retrieve are random strings (basically referral codes... if I'm understanding correctly), your database needs are pretty simple. If you're not familiar with things like PHP / MySQL, and you don't want to learn, it might be worth reaching out to some server-side developers for help. Unless there's more to it than you describe, you can probably find someone to help you for relatively cheap.
Good luck - and I'm sorry there isn't a simpler answer for ya.
You can send data using NSURLConnection. Just create an NSMutableURLRequest and call its -setHTTPMethod: method with “POST” as the HTTP method. Then, set its body and header fields appropriately, and you can use NSURLConnection to send the data.
Im new to website development and design so apologize in advance if the question is redundant.
I have a program where a client, using a URL string fetches a XML file from a webserver. This would be no problem right if it were a simple URL with no security or no CMS (like Joomla) involved: Just put the exact URL string and the client gets the file from the web server, done.
But, how would the process work if the URL is on my site hosted on GoDaddy and using a Joomla CMS?
Im trying to understand how the same process of fetching a file works on a hosted server using a CMS. Since I just made the transition from my site being on my school's servers to having a Joomla website Im hosting on goDaddy.
I mean where would I put the file if I also want the file to be accessible only if the client authenticates itself first. Just to be on the safe side. I mean is this how normally things work in mobile apps? I have a client program thats a iPhone app and within the app I have a XML file which is used as a data source for my UITavleView, but I want to check some URL to see if an updated version of the XML file exists. My app side programming is mostly done, now Im trying to learn the server side things I need to do to make this process happen with Joomla and my own hosted site
I donot understand how would the process work in that case. I mean, what are the things I would need to do on the server side to and the client side to make this possible?
Please help me understand or if you could point me to some links where these steps are illustrated...or if you could give me some Google key words I can search for to learn about this process.
thanks a lot
The fact that you have a CMS does not generally change how you access a file within the file structure of your domain unless the CMS protects certain directories. In this case, Joomla does not so you can directly access any file you wish. Depending on the sensitivity of the information you are trying to retrieve, you can protect the directory through your domain management panel. If it's not particularly sensitive, the authentication can be done by the app since the URL you are accessing can be easily hidden from the user.
It seems like that would be the simplest solution since the app will have access to user information by nature of where it resides.
