Now my question is, I want to store data in file system rather than storing data in SQL or ORACLE.
I want my data in file system storage for Insert, Edit and Delete opration with keeping relation with objects too.
I am a C# developer, Could anybody have thoughts or idea on it. (To store data in file system with keeping relations between them)
Which is the better alternative when allowing file uploads on a page (through a Gridview populated by a coded DataSet)? Store the image itself in the database or to store only the path name to the saved file in file system. If it matters, I do not expect to have more than a few dozen images stored in the database at any given time.
View 7 RepliesI need a place to store images. My first thought was to use the database, but many seems to recommend using the filesystem. This seems to fit my case, but how do I implement it?
The filenames need to be unique, how to do that. Should I use a guid?
How to retrieve the files, should I go directly to the database using the filename, make a aspx page and passing either filename or primary key as a querystring and then read the file.
What about client side caching, is that enabled when using a page like image.aspx?id=123 ?
How do I delete the files, when the associated record is deleted?
I want to maintain different user authorization lists for different environments. I know that connectionstrings can be broken out in an external file with configSource, but how would I do this for the following?

<allow users="someuser3"/>
<deny users="*"/>

I have this file upload control. I have created a folder name "images" in my visual studio project. I want to upload image into this folder. BUT, when I am uploading a image, system does not show any error. It is uploading the image. But I cannot see it into the "images" folder. But, when I browse the folder from my computer like if I go to c:/my documents/vs project/my project/images. i can see the uploaded image. Then why the image is not visible from my visual studio?? as the image is not visible in my visual studio project, user can not see the uploaded image. my code is as below:

View 6 RepliesWe have the data in excel file and want to upload the same into Oracle table.To achieve this we are using following query
insert into [ODBC:Driver={Microsoft ODBC for oracle};connectionstring].tablename (select * from sheet$ )
This is working fine for less records but when the record count increases following is the error faced. Error : System Resource Exceeded
We tried the following:
1. We tried to remove connection pooling for oracle.
2. We tried to remove connection pooling for excel.
3. We also verified that only one connection for each (oracle and excel) is open.
Our assumptions:
1. Either the server setting is the issue
2. Jet oledb Driver is the issue.
I'm not sure where this should go (I don't know whether it's a database problem, or a code problem), but I think it's a code problem, so I'm posting here.
I'm working with a database that is storing images (actually, it's a modified version of the AdventureWorks database from Microsoft), and I'm creating a form that will let you upload a file. I've got a business object based on the table that I'm using (Production.ProductPhoto) and I'm using two stored procedures to either get (Production.ProductPhoto_Get) or add (Production.ProductPhoto_Add) an entry from/to the table. The image is being stored as a varbinary field in the database, and a Byte() in my business object.
The problem I'm having is that when I'm adding a new entry and uploading a file, the length of the file uploaded is correct (so I assume everything is going smoothly), and it gets passed along to my ProductPhotoProvider DAL class where I create a DbCommand and add the parameters for my stored procedure. The information is all added to the database successfully, and I'm returned the identity of the new entry as expected -- however, when I try to read this image back, it seems that the length is 1. I've put in break points and stepped through everything, and I don't know what's going on.
I think that I know my ProductPhotoProvider class is at least reading things correctly -- I can display other images from the database (that came with the database, that is) just fine. Mine just all come back with a length of 1.
I'm just hoping someone knows what the hell I'm talking about; I have a lot of programming experience, but this is my first major venture into ASP.NET. I have no idea which parts of my code are relevant, so I'll just post my Add and Lookup functions for now?!
[Code]....
My ProductPhotoProvider class is based off of an abstract class called AbstractDALProvider (which I can also provide if needed). I can provide the rest of my project, if needed, too.
Oh, and for good measure: I was told that when you used to store images in Microsoft Access, there was some sort of problem when retrieving the data and you'd have to strip the first 72 bytes of data from it, or something. I can only assume that this is not a problem here, because I have no problem displaying other photos that were not created by me.

This works in other browsers but not in chrome. I am trying to allow users to upload large files and have an ajax call to update them on the progress of the file upload.
So a unique ID is generated on the client side and added to the action of the form before sending. Then the form is submitted (form only contains a file upload input) and an ajax call is made to get the progress of the upload. The ajax call goes to another page and uses the ID to lookup the upload.
I am using JQuery 1.5.1. Debugging this and putting something on the error function give me nothing other than "error". Not very helpful. I used Chrome's debugger and it just says failed to load resource xxxx.aspx. xxx.aspx is the URL i needed. Turns out that there seems to be some sort of conflict between the form and the ajax call.
Is it better to store images directly in a database or to just store the name of the file in the db and display that file? I would think that just storing the filename of the image would keep the db size low...

Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
