View 9 RepliesPros/cons Of Reading Connection String From Physical File Versus Application Object
Apr 9, 2010my ASP.NET application reads an xml file to determine which environment it's currently in (e.g. local, development, production).
It checks this file every single time it opens a connection to the database, in order to know which connection string to grab from the Application Settings.
I'm entering a phase of development where efficiency is becoming a concern. I don't think it's a good idea to have to read a file on a physical disk ever single time I wish to access the database (very often).
I was considering storing the connection string in Application["ConnectionString"].
[code].....
I didn't design the application so I figure there must have been a reason for reading the xml file every time (to change settings while the application runs?) I have very little concept of the inner workings here. What are the pros and cons?
Databases :: Reading Excel File Without Saving To Disk First?
Aug 31, 2010I need to be able to read an excel file from a file upload control but I can not save the file to disk first, it must be done in memory.
[Code]....
Above is my code for reading the data file if it IS saved to disk, but again, I have to be able to do this without saving the file to disk, it must be done in memory. I have not been able to find any sample code anywhere on how to do this from memory, everything seems to force the file be uploaded, saved to disk, and then read in the connection string, which again I can not do.
Web Forms :: Reading A File Into Stream And Saving It To A Location?
Oct 8, 2010I have a third party CMS system that can create forms but can't manage true File upload capabities. I am able to get users brows for thier file and have the value submited to my custom .net code behind page for processing. So I end up with like "C:somefilefoldersomefile.doc".
But on my processing page I want to read this file (like the file uploader) and save it to a location. I tried using the file uploader control (but have it not visible) but realized I can't preset it as I was planning to set it and do the normal processing from there. Is there another way to do this?

Oct 20, 2010I'm getting tired figuring out this error. Well, Basically. I have uploaded my ASP.net website to a server (IIS installed) as well as the VB project I made.
BOTH are connecting to a DB named CLIENTS.
the website uses a datagrid to show data, while the VB Project updates the DB based on a monitored folder.
The Problem is If the website is opened first the VB project shows an error "Unable to open the physical file (MDF). Operating system error 32 (error not found)" and Vice Versa if the VB project is first started.

Reading And Saving An Image From Url?
Mar 29, 2010I would like to be able to read an image based on a url hosted elsewhere. To be clear, this is a legitimate service that is provided and they do allow caching of data, so I'm not trying to steal someone elses data.
So far I have the following code:
public static byte[] GetBytesFromUrl(string url)
{
byte[] bytes;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
WebResponse resp = req.GetResponse();
The area that I'm looking to improve on is the emboldened line. I think it would be better to read in say 1024k chunks until the file end. Can anyone help me out with the syntax for this?

Reading An Embedded File From A Custom Server Control An Rendering It?
Mar 31, 2010I currently have a file "abc.htm" in my Custom Server Control Project and it's Build Action is set to Embedded Resource.Now in the RenderContents(HtmlTextWriter output) method, I need to read that file and render it on the website.I am trying the following but it's to no avail:
protected override void RenderContents(HtmlTextWriter output)
{
var providersURL = Page.ClientScript.GetWebResourceUrl(typeof (OpenIDSel), "OpenIDSelector.Providers.htm");
var fi = new FileInfo(providersURL); // <- exception here
//the remaining code is to possibly render the file
}
This is an example of how the providersURL is:

Saving Ntext Data From SQL Server To File Directory?
Mar 15, 2010A variety of files (pdf, images, etc.) are stored in a ntext field on a MS SQL Server. I am not sure what type is in this field, other than it shows question marks and undefined characters, I am assuming they are binary type.
The script is supposed to iterate through the rows and extract and save these files to a temp directory. "filename" and "contenttype" are given, and "data" is whatever is in the ntext field.
[code].....
This works, but the file should be saving to the server instead of popping up save-as dialog. I am not sure if there is a way to save the response to file.
