I am using VB to upload image files to my server but am having problems. How can I use the ContentType to filter only image files? This is my code for my upload button which does not seem to be working. I can only upload bmp files:

I'd like to allow users to upload a .pdf file via the file upload control (if that's the best method), save the file to the db and then retrieve it so they can click on a link and open the .pdf they've uploaded. I've been looking for a tutorial on how to do this but keep running into methods of saving the file directly on the server in a directory, not in SQL server (using Linq and VB by the way)

I couldn't upload anythink to a server using FileUpload control (access denied exception). I changed permissions for required folder and gave aspnet user full access. It did not work (I got access denied exception). Than I changed permissions again and gave full access to all users on the machine - now upload works. As far as I understand, it makes my site vulnerable and I should give full access to only one user. Could anyone tell me which user IIS 7.5 uses?

View 3 RepliesI am working on some project where I am needed to allow users to upload files, but only in pdf and .doc format. Now I know how to let users upload files, but I do not know how to check whether an uploading files is pdf and .doc or not. How could I know that? And how could I know the size of each file, for the file should be no greater than 3 MB?
Also, I have alloted a separate folder for the files that are uploaded by users. I have one page that displays the links to download the files in that folder. I needed to know how could I keep the track of the folder, for the files get uploaded every time? Or in other words, how could my 'downloads page' know about the files in that folder and create links for each file in that folder for the download? Also, if I create a link of a file for downloading purposes, will the file be downloaded when one clicks the link?
I have some code that allows users to upload file attachments into a varbinary(max) column in SQL Server from their web browser. It has been working perfectly fine for almost two years, but all of a sudden it stopped working. And it stopped working on only the production database server -- it still works fine on the development server.
I can only conclude that the code is fine and there is something up with the instance of SQL Server itself. But I have no idea how to isolate the problem.
I insert a record into the ATTACHMENT table, only inserting non-binary data like the title and the content type, and then chunk-upload the uploaded file using the following code:

uploading multiple files from client to server with asp.net.I have been looking at the asp.net upload control but that is for one file (unless someone knows a better way to do it).
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload.aspx
For what I want to do I don't even really need a browse. I know the files off of the client are at a certain location. Is it possible to create a collection of *HttpPostedFile*s and upload those?
http://msdn.microsoft.com/en-us/library/system.web.httppostedfile.aspx
I don't think it is possible but would be glad to be proven wrong. Is there a different asp.net method or control that will easily allow uploading multiple files from client to server?

I have made an application for some customer that I'm going to transfer to a webhotel.I want to make sure that the application is not copied and used elsewhere without my knowledge. So I have thought of stripping the aspx files from their code behind, that is not the aspx.cs file itself. But from all code inside the cs file, not the one that is automatically generated like page_load etc, but everything else. And when done, then just upload the compiled DLL file(s). Does this work? Are there something to be mindful of if I carry out with this plan.

View 1 RepliesI've got a project that's going to go on a dedicated server environment. I'll be uploading images to the server, but saving them outside of the virtual folder path of the actual website, like so:
protected void UploadImage_Click(object sender, EventArgs e)
{
string newFile = "C:\Images\myImage.jpg";
this.cb_fuMainImage.PostedFile.SaveAs(newFile); // from webform <input id="cb_fuMainImage" type="file" runat="server" />
}
Now, this works fine on my home computer. Is there anything I'll need to do with IIS or ASP.NET (possibly in web.config) for this to work properly on a production machine? Settings or permissions that may need changing?...
It will be on Window 2003 with IIS6 and ASP.NET 3.5 SP1.

and i found it, here http://forums.asp.net/p/1480079/3451771.aspxi can fairly easily code for a general dbase (name, address, etc..)my question here with this code is...where does my dbase info go?
my dbase info
dbase name = files
tablename = fileTable
column names = fileOne, fileTwo, fileThree
the file upload object is called "fileupload1" and this all goes with a "submit" button
also, that is pretty much for one file, what if the user is uploading more than one file? do i just add more if/then statements, one for each fileupload object?
while uploading the file on the local host it works fine.but the same coding does not work on the webserver. is there anything to do with the foldr read and write permissions.i m using the server.map for finding the path of the browsed file.

{

{
string fold = "images";
string Name = FileUpload1.FileName;
