I've got a website that runs on a shared hosting environment, using ASP.net 2.0 (C#) and MS SQL Server 2005. I've recently been asked if I can integrate my website with a piece of third party desktop software that uses the Access runtime as its database (transparent to the end user).
Primarily I want to be able to offer users of my website the option of exporting their data into the Access database on their local machine. The data schema's match sufficiently, the question is how to actually do this, and in the simplest way possible for the user.
Simply having a webpage update the local Access database isn't possible due to the obvious security restrictions. I've considered asking them to upload the Access database to the server, so I can migrate the data then allow them to download it again, however the competency of the users of this software is such that even locating the Access database, let alone uploading and downloading it from the website might be too complicated.
I've also considered if Adobe Air or Silverlight could help here, but don't know them well enough to know for sure. Similarly I'm assuming another exe could be written to perform this task that the user could simply download and run, however my experience is in web development, not program development, so this isn't a 100% certainty for me, or an ideal development option for me.
So, can this be done, and if so what technique can achieve this, with the stated aims being ease of use for the end user, followed by ease of development by someone with web development as their main skill. Many thanks!
You may find this answer of interest: Best way to stream files in ASP.NET
It is about transferring a file from the server. You could save Excel or CSV and use that to update Access.
Instead of trying to do this in a web page you might just expose some views from your sql server to some client specific logins.
Then within the Access application, allow them to tie to your sql server. You might even provide an access application for getting the data from your site and stuffing it in their local access database.
In my work we have done something similar that is transparent to the user by creating an ActiveX control. The problem is that you are limiting the users to use only Internet Explorer.
I think that the best way to achieve what you are trying to do is by installing a service in the client's computer. If creating a service is beyond your experience you can post a project in a place like oDesk and find somebody that can help you with the development for the money that you are willing to pay to complete your project.
Good Luck.

This is a hypothetical question that I don't seem to be able to find an answer to. In theory, could you write a desktop program which allows you to alter the database of a personal website? A simple example would be a blog, where instead of having to go online and log into Admin section of your website, you would have a desktop app where you could write a blog offline and once you have internet it would automatically update your website?
Would this theoretically be possible?
Yes, it is possible. However, probably not recommended as you would have to allow direct connections to your database through the firewall unless your desktop application made the same http/https pots that the website does when updating the database. At that point, you're just creating a new UI that calls the old UI to do the same actions.
If you are running Windows you could use the free tool Microsoft Live Writer for that. I am sure you can find other free tools for other OS out there.
There is not also an Open Source version of it Open Live Writer
May not be the best place to ask sorry if that's true.
I have worked on SQL and while I never worked on QuickBooks I am hoping it is possible to connect to it and just use it similar to a SQL Database. I am wondering I am wondering if it is possible to connect to QuickBooks using ASP. My purpose is to create simple forms and insert the data into QuickBooks similar to what is done on SQL.Occasionally I would just generate reports as well using web pages. All I am wondering is does ASP have the capability to connect to Quick Books and if so can I also run query's similar to SQL and is there any sources or reference available for research ? And what my options are for setting this up. If I have to use asp.net as a last resort that is fine too, though I would prefer to have to be without it.
Thank you
Update #1
While i am working on getting the Version of Quick-Books here is what information I have.
I plan on using ASP-Classic, and I want to develop web forms so this would be a website that can be accessed. This will not be a desktop application I plan on making but various webpage's where you can view Quick-books data, and insert records into Quick-books using forms, similar to what I do for SQL. And the Version of our Quick-Books is 2013 Enterprise Windows Desktop USA edition.
All I am wondering is does ASP have the capability to connect to Quick Books
Yes.
can I also run query's similar to SQL
Maybe.
QuickBooks itself does not provide an SQL-based interface. Communication with QuickBooks is via XML. However, QuickBooks Enterprise comes with something called QODBC which provides an ODBC interface to the XML interface QuickBooks provides, which might get you what you need.
One problem you want to watch out for -- there are times when you won't be able to connect to QuickBooks. e.g. it is not an "always-on" solution like a typical SQL database is. If you're in single-user mode in QuickBooks, or someone closes QuickBooks, or someone is doing a QuickBooks backup, or someone is updating QuickBooks, then you won't be able to connect. You'll have to plan for this in your application.
A better solution might be to use the QuickBooks SDK (specifically the QuickBooks Web Connector). If you download and install the SDK there is example code included. The SDK install also includes about 600 pages of PDF documentation on topics which you are asking about.
Striking out the below stuff since you've provided more details now: But unfortunately you didn't provide anywhere near enough information for anyone to actually give you a decent answer.
How about providing some actual details so that people can actually help you? Like, maybe:
Is this QuickBooks ONLINE, or QuickBooks for WINDOWS, or QuickBooks for MAC? (they are three entirely separate products, with entirely separate sets of capabilities)
What version/year/edition/country of QuickBooks?
ASP classic or ASP.NET?
Is this a website you're connecting from, or is this a desktop application, or...?
I am trying to deploy my WPF application to some users who are outside of our corporate network. Everything works great on our LAN but I can't get the updates working when I turn on security as the user is never prompted for their login details?
Does anyone know of a way to secure my ClickOnce files so that only my users can access it? I am not allowed to put this software up without it being secure.
Any help much appreciated.
There is no way to secure your files as the ClickOnce runtime will blindly return to it's deployment point and never keep hold of the users original credentials. I have heard of ways of getting round this using various techniques but its a fair bit of work.
This might be of use www.clickoncerevolution.com.
You could also always consider an MSI installer but you won't get the automatic updates.

Internally, you can restrict access to the files on the webserver. Externally, there's not much you can do easily.
We handle this by having our customers log in when they run the application, and we verify their credentials against backend services (running on Azure). So they can't run it unless they can log in.
If you don't want to do that, I'll share this article with you. It shows how to serve up your ClickOnce files from a SQL Server database by intercepting the requests to the webserver and responding. If you were smarter with web applications than I am (not a high bar, mind you), maybe you could figure out how to intercept and ask for authentication credentials at that point.
And here's an article from CodeProject where they show one solution for what you're trying to do.
I have just completed (basically) a beginner's database application with SQL Server and Visual C#. I am using Visual C# Express, not the full-scale Visual Studio thing, which apparently makes deploying the application properly a bit more complicated. I've seen where some other people have asked about how to deploy such an application from that IDE, but I'm not able to fully understand and use some of the answers that they've been getting back.
Therefore I must ask how to deploy this application properly, but I must also ask that there be a simple walkthrough given. College doesn't teach much about how to deploy these things, so I'm very newbish at it. Thanks!
I don't know of an automated way to deploy the database. If it's the first time the database is hitting the server, I backup on the source, and restore on the target...simple.
As far as the code, here's what I do:
Publish (right-click, Publish) the code to a local directory (I use C:\Websites\SiteName).
Use and ftp client to promote the output to the server.
Make any necessary adjustments to the web.config to point correctly to your target database.
When and if you need to make changes later, you might want to consider a tool I use for this purpose, BeyondCompare. It can perform a diff between your local files and the target site via FTP, and tell you exactly what you need to deploy to make it work. This won't detect changes in your db, however, though there are plenty of Sql diff tools along the same lines. My general principle is "make the local site work perfectly, and then make the target site just like the local site".
Things to watch for in #3 above are that the target address is right in the connection string, along with whatever security credentials you will need to connect to the db.
HTH.
I am working on an in-house, iOS app that will need read-only access to a SQL Server with multiple databases. I know the stock answer here is "write some web services", but I'd like a solution that is self-contained. Is there any way to directly connect to a SQL Server database from an iOS application? I'm thinking something like a basic ODBC connection.
I've seen a lot of users asking this question, but very few answers other than "write a web service." Is that really the only way?
A web service is indeed the only way, but Red Gate's written one you can reuse:
http://www.mobilefoo.com/iSqlServerSDK.html

It's not officially released yet, just in beta, so keep in mind that features & prices may change.
Actually the easiest way is to create a MVC 3 or 4 asp.net web application. call the web methods. You don't need any API to pay for.
I use SBJson to serialize domain object and then send the objects as serialized jSOn to MVC 3. It's super easy to do. I even send images with base64, so it's .net compatible.
See my blog post with sample code:
http://nickturner.wordpress.com/2012/10/09/107/
So, after much searching and trial and error, unfortunately the best (only?) way I've found is indeed using Web Services.
Fortunately, Linq to SQL makes the WCF-creation-side incredibly easy. Once I got someone at work to walk me through setting up a Windows web server and adding the web service (and buying access to an online web server), the Windows side was up and ready to go.
I'm still working through all of the syntax stuff on the SOAP interaction side, but keeping my different methods somewhat similar in structure allows me to tinker a little until it works. By this time, I think I've gotten it to work pretty well.
So, both answers I got back were (disappointingly) correct. The only way to interact is through a Web Service. Even the 3rd party solutions they mentioned were really just convenient wrappers around the same type of technology. As it turns out, I'd rather have finer control over the process.
One word of advice: Get a real, external web server. I tried doing this on a non-Server Windows VM on my iMac/MacBook Pro, and it was like pulling teeth! Once I actually got access to an external, full, stand-alone web server, the process was much more streamlined and easy. Do yourself a favor and take that headache out of the equation!
There was a SQL ISAPI extension as part of SQLXML, but I think it has been deprecated: http://msdn.microsoft.com/en-us/library/aa226559%28v=SQL.80%29.aspx
This was effectively a pre-built, and relatively open, web service - so I'm not sure this counts as a direct connection.
