Vb.net - Open A File Stored On A Shared Area?

Jan 12, 2011

I'm working on a web application that stores some Office document (and any other kind of doc) on a remote shared area. I need to allow user to view the files available on shared area using my web application, how can I do that? Some years ago I solved this issue with Java / JSP opening into an output streaming the file, how can I do the same with ASP.NET and VB.NET? there is another way to solve my issue?

This is how I organized my application:

C:Webapp -> Webapplication
emoteserversharedfolder -> shared area

The owner of IIS process is the only user that can write / read the shared area.

Web Forms :: Response.TransmitFile --- Open A File From DataBase And Send It To Browser?

Aug 25, 2010

There are bunch of files stored in a DataBase as varbinary/image data. I am writing a program to extract these file data and send them to the browser so file can be opened or saved. My method is,

[code]....

BUT this method creates a file in the Server and then transmit to the browser. Means 100s of files will be created in the server when I open 100s of files with this process, naturally I want to avoid that.

Is it possible to do this without creating a copy of the file in the server ?

How To Open A Database In A WebMatrix C# File

Nov 19, 2010

In the webMatrix examples, which I have working, it's very easy to access a database. Only three lines are necessary to get up and going:

@{
var db = Database.Open("LOS");
var selectQueryString = "SELECT * FROM wknTest";
}

and a little later,

@foreach(var row in db.Query(selectQueryString)){

There's no using's, no connection strings, all that happens behind the scenes. But now I have enough complicated c# code that I want to separate it into a separate C# file. How would I do the above, but in a C# file residing in the app_code folder in a webMatrix project?
