We have a file upload feature in one of our websites developed in ASP.NET and C#.NET. We would like to scan the files for viruses automatically before they are being uploaded into our server. We are using AVG server edition on our server. How can we enable this feature.

i want to be able to scan a folder and its sub directories for all the files that exist in it. the results are then feed into a list box or any similar control
additional it would be great if the results are entered and also its path
eg:
File1 C:folder1folder2file1.exe
File2 C:folder1folder2dd.dll
File3 C:folder1explorer.exe
File4 C:folder1folder2folder3document.docx
File5 C:folder1
eadme.txt
We are using HttpPostedFileBase to upload files to our asp.net mvc application. Is there some smart way of analyzing the contents of the file to determine the actual mime type by looking at the actual binary stream?
I want to make sure no .exe files or similar stuff are uploaded, just want to accept a number of files.
Something like a preflight on the file that is uploaded to extract information programmatically and determine the file type.
I have developed a web based application in ASP.NET and C# where users have the facility to upload files on the server through this application I want the application to Scan the uploaded files for viruses before saving on the server. Same like when we attach files with our email in Yahoo. Any API which can be integrated in ASP.NET application or any other way you can suggest. We can purchase the licensed version of a product which can achieve this.
View 3 RepliesIn continuation to my previous research at this link : Security Risks or concerns with the use of FileUpload control of asp.net - how to Scan files during upload, also how to intimate user if file is virus affected and abort the operation. In addition to above, we have McAfee Antivirus installed on our servers. I heard that there is some APIS for this work for Symantac Antivirus but I am not sure about McAfee antivirus.
View 1 RepliesIs there any difference between accessing a property that has a backing field
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?

I want to restore .bak files from a server directory into database. The problem is it should behave automatically. Whenever a .bak file will be uploaded in that specified directory of the server that file will be restored. It may happen by using sql procedure which will restore all the .bak file which it will find at a certain time in that specified directory. Or, it may happen by using asp.net program which will run exclusively on server and call a sql procedure to restore a backup file whenever a backup file will come in that specified directory. But I am not getting how to figure out this ideas programetically.
View 2 RepliesI'm frequently adding a lot of content files (mostly images and js) to my ASP.NET project. I'm using VS publish system, and on publish, new files are not published until I include them in the project. I would like to auto include all files in specified directory. Is there a way to specify wich directories should be auto-included in csproj file or anywhere else?
View 3 RepliesThe sequence of events is as follows:
1. A piece of software running locally on my pc periodically uploads (approximately every three minutes) to my webserver an xml file comprised of six fields. The file size is < 1K.
1a. The file name is always the same. ie. filename.xml is uploaded. Three minutes later, filename.xml is uploaded again, this time with different contents. I have no control over renaming this file.
2. A chunk of code that parses the xml and inserts the six fields into a database
3. Deletes the xml file
4. Waits for the next xml file to appear in the folder
5. Goto 2.
The locally running software uploads the file without issue. So far, I'm able to parse the xml, do the database insert and delete the file manually by refreshing the browser window and subsequently running the code in the .cshtml file. What I'm having a hard time conceptualizing is what the best way is to set up an automated event/method that watches the folder and when a new file appears, write it to the db without user intervention. Also, where would I put this code? _AppStart? Do I need to start a FileSystemWatcher event on the server somehow? I'm kinda stumped as to how best to proceed.
We are currently updating our policy page on our intranet. Currently the page is written in ASP and connects to an Excel spreadsheet that serves as an index, which contains policy name and number. We also have a directory that contains all of the policiesnamed the policy number. The control that is currently being used will get all of the policies listed in the index and create links for them. We do not have to manually create the hundreds of links we just update the index. Does anyone have an idea of a control or a way I can accomplish this in asp.net?
View 1 RepliesI just inherited an ASP.NET WebForms web application that I was tasked with refactoring. One of the features is a file upload and while debugging I noticed that as soon as a file is posted to a certain page/handler, it is automatically uploaded to the root directory of the application. The file is then moved to the proper location. I can't seem to figure out whats causing this automatic upload of the file. Is there something I'am overlooking in ASP.NET WebForms that allows this to happen? Is it an IIS configuration or something?

I've been manually adding the following line every time I create a new user control / web form in one of my ASP.NET web forms projects: Option Strict On. I can't just set it in web.config because it's a legacy project that has user controls / web forms that would bomb out if we turned on option strict for the entire site, so the current solution is to apply it to all new user controls / web forms and slowly update the older pages. Is there some sort of Visual Studio setting / template I can change so that "Option Strict On" is applied automatically when Visual Studio creates the codebehind files?

View 1 RepliesI manage a large asp.net site which has previously been converted from static html site to asp.net. For several reasons (mainly SEO) we decided not to rename all the files to .aspx back when we originally converted the site. This was very easy to do by simply adding the buildProvider and httpHandler to the web.config.
<buildProviders>
<add extension=".html" type="System.Web.Compilation.PageBuildProvider"/>
</buildProviders>
<httpHandlers>
<add path="*.html" verb="*" type="System.Web.UI.PageHandlerFactory"/>
</httpHandlers>
Now I am upgrading the site to use Asp.net WebPages with Razor cshtml files. I can rename all the files if necessary, and use url rewriting to make the urls stay the same, however it would be much easier if I could just configure the web.config to tell it to parse .html files as if they were .cshtml. I have searched around quite a bit, and could not find anything equivalent to the PageHandlerFactory for razor pages. It appears as though it is just an internal mechanism in the .net 4.0 ISAPI handler.
The site is currently running on Windows 2003 server and IIS 6. We will be upgrading to 2008/IIS 7.5 in the near future, but I'd prefer not to wait for that. Is there any way to get the .html files to be parsed by razor as if they were .cshtml files?
