I have a web site that you can upload images, the image path is saved in the ImgPath field in the data database and retrieves the image and displays it in the grid view. I want to be able to delete the image from a folder within my project when I delete the record. I'm trying to delete it from the Detailsview_ItemDeleting event.

How can i take a file name see if there is a R on it then remove the R so i have orignal file and delete it? So in other words if a file has a letter R on it. It was resized need to delete orignal.
View 4 RepliesWell basically I can't find anything regarding storing an image within a folder on the server, as appose to the SQL database. I have already written code to store the image within my database, but I also need to store the image as a physical entity for CSS purposes, here's a part of my code which can probably be used.

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.

What is the best approach to storing images in a file system. Currently I am separating the images by day, month and then year. I am also hashing file name so that no two files will be stored with the same name. Lastly, how would I go about using the image file address in a forum?
View 3 RepliesWhich 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 1 Repliesi am downloading a file from a server and i plan to delete the file that i have downloaded on the server after it gets downloaded on the client side. My download code is working fine but i dont know when to put the command to delete the file.
string filepath = restoredFilename.ToString();
// Create New instance of FileInfo class to get the properties of the file being downloaded
FileInfo myfile = new FileInfo(filepath);
// Checking if file exists
if (myfile.Exists)
{
// Clear the content of the response
Response.ClearContent();
// Add the file name and attachment, which will force the open/cancel/save dialog box to show, to the header
Response.AddHeader("Content-Disposition", "attachment; filename=" + myfile.Name);
//Response.AddHeader("Content-Disposition", "inline; filename=" + myfile.Name);
// Add the file size into the response header
Response.AddHeader("Content-Length", myfile.Length.ToString());
// Set the ContentType
Response.ContentType = ReturnExtension(myfile.Extension.ToLower());
//// Write the file into the response (TransmitFile is for ASP.NET 2.0. In ASP.NET 1.1 you have to use WriteFile instead)
Response.TransmitFile(myfile.FullName);
// End the response
Response.End();
}
Now i know the response.End() will stop every thing and return the value, so is there another way too do so. I need to call a function
DeleteRestoredFileForGUI(restoredFilename);
to delete the file but dont know where to put it.. i tried putting before and after Response.End() but it does not work.

View 1 RepliesCurrently, I am storing images and video clips in my database as a varbinary(max).
The problem is that when my front-end goes to retrieve and play the video, it takes an excessive amount of time to download.
For example, I have a video file: test.avi (5mb). If I attempt to read from database and play avi, it takes about 40 seconds. If I attempt to play this test.avi from the filesystem, it takes about 10 seconds to load.
I have investigated compression/decompression, but those seem to be as time-consuming as just loading up the raw data from the database.
Should I scrap storing video clips in the database, and go for a file system approach. I would really like to keep everything clean, secure, and organized. Which is why I am storing images, video clips, etc. in database.

View 2 RepliesI have a file delete option for the files uploaded by the user, user can upload many files at a time.The uploaded files will be stored in a folder in server and when its is deleted its is moved to trash folder from where it will be manually cleared.
when a user tries to delete many files in the web page IIS get hangs and all session is expired. This case only present in server,in local host this issue is not available.
ALL the operations is carried out completely ie
Database gets updated. Files is moved from upload folder to trash folder in server.
I cannot determine what is going wrong,I just tried to delete many files totally around 35-36 MB. Is the issue with process taking long or is there any changes have to be made in order to perform large files operation, my project is done on VS2005 which is running in 2008 server.
I a webproject in asp.net my project worked fine in my pc but after uploading it to a iis server it is not working.My webproject is to delete a file,

I have added the following code to my web.config file:
<system.diagnostics>
<trace autoflush="false" indentsize="4" >
<listeners>
<add name="myListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="d:debugging.txt" />
<remove name="Default"></remove>
</listeners>
</trace>
</system.diagnostics>
And I have written this line for sending trace output:
System.Diagnostics.Trace.Write(sID + " tracing id");
But, I can not see any "debugging.txt" file created on my d: drive and there is no trace output.
Error message says there is another application using that file at the moment.However, I cannot find where the problem is since I have already disposed all the instances based on that file.What's more odd is after I close the debug page, I can easily remove that page in OS file system.

View 4 RepliesI need a basic system that uploads a file to the server and stores the details in a database, with the ability to add/ edit/ delete whats there.
Most of the solutions I've seen have been far to indepth. I'd like something very simple so I can pick it apart and modify it.
I'm using System.IO.File.Create to create a file. I'm not writting to it with a stream writer, just creating it.
I get a server error in the front end when the app trys to open the newly created file - that the file is in use. Garbage collection then seems to come along and a few minutes later all is OK.
Now I know if I was using Streamwriter I would have to close it. Does the same apply to creating?
I've read that opening a stream writer to the file then immediately closing it will fix this.
