Web Forms :: To Customize File Uploaded?
Dec 14, 2010
I wanted to customize/Restrict the File Uploader control as follows:
1. To restrict Users to not to upload some type of file like.exe
2. To restrict the user to a specific size limit.
I also wanted to be able to display appropriate messages to the user if the abover restrictions are violated.
Can I use the validations control to achieve the above goals. As I am already using these controls to display appropriate messages to the user in case of wrong/invalid data.

When I upload a file through a web page to a directory on the webserver the file does not inherit the parent folders rights. So when a user tries to access the file from the local network after the upload they recieve access denied. How can I set the rights on the file after the upload or get the rights to set correctly when the file is uploaded. The file uploads correctly but only has the rights of Network service, system,internet guest account and IIS_WPG. I need it to have a specific user or everyone which the parent folder has and is set to propogate permissions.

I was so proud because I researched saving files and figured out how to extract the file name from what might be the full path. However, this doesn't work as I had expected. I still get the exception!
Here's the function that saves the file:
protected string SaveFile(HttpPostedFile file)
{
string savePath = Server.MapPath("~/Articles/");
string fileName = Path.GetFileName(article.FileName);
savePath += DateTime.Now.ToString();
savePath += " _ ";
savePath += fileName;
article.SaveAs(savePath);
return DateTime.Now.ToString() + " _ " + fileName;
}

My website provides a facility to upload images, using the ASP.NET FileUpload control. We accept both jpeg and tiff formats but I have just decided that all tiffs should be converted to jpegs at the time of upload. If possible, I want to avoid saving the original tiff to disk. I would any sample coding for achieving this conversion prior to saving (ideally in VB.NET, though I could always run C# code through a converter).

In my application I've allowed users to upload Excel 2003 .xls files, and import them into a Gridview. This has been working fine using the following connection string:
[Code]....
Now my users are using Excel 2003, 2007 or 2010, I need to allow the newer file extensions (.XLSX) to be accessible too.
Therefore, within the connection string above I presume I could change the Excel version from 8.0 to 9.0 or 10.0 respectively, but is there much difference between Excel 2007 and Excel 2010 files?
If so, is it possible to 'detect' the Excel file version so that I can use the appropriate connection string to read the data from the files?

Below is the code for "Upload" button when uploading any file:
if (contenttype != String.Empty) {
if (File.Exists(Server.MapPath("~/Folder/'" + Txt.Text + "'/") + filename)) {
LMsg.Visible = true;
LMsg.ForeColor = Color.Red;
LMsg.Text = "File name '" + filename + "' already exist. Please change the File name to save this file";
[Code] ....
File upload control allows maximum file size is 4MB. If file size increase to 4MB it shows error page like "the page can not displayed".
I want to increase the size of uploaded files to max 10 MB not more than that. If file size increase to 10MB, it should show message.

We are going to start accepting resumes online but I need to know if the uploaded files will be virus scanned before I park them into the database. I thought this would be a server thing but the server admin and the security guy both said they didn't know. We already have a firewall and antivirus software, I just want to know how things work with native ASP.Net controls and not a product to try.

I want to keep the uploaded file name to make it possible to users to download the file under the same name. But how can I implement it? The one option I see is to store each file to folder with unique name (GUID, for example).
