C# - Examine The File Content Being Uploaded?

Sep 6, 2010

I'd like to get both C# and VB.NET sugestion.

I have an ASP.NET FileUpload control, which allows only image type. I used RegularExpressionValidator like below.

<asp:FileUpload ID="fuPhoto" runat="server" TabIndex="40" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator3"
runat="server" ControlToValidate="fuPhoto" Display="Dynamic"
ErrorMessage="* You can only upload .jpg, .gif or .png image types."
ValidationExpression="^.*.(jpg|JPG|jpeg|JPEG|gif|GIF|png|PNG)$">* You can only upload .jpg, .gif or .png image types.</asp:RegularExpressionValidator>

This method will only verify the file's extension, not its actual type. Once I receive the file, I want to examine its contents to determine what it really is, in this case image only.

How do I examine the file content being uploaded?

Forms Data Controls :: How To Determine Excel .XLSX Version From Uploaded File

Aug 10, 2010

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:


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?

ADO.NET :: File Upload In MVC Storing As SQL Database?

Nov 8, 2010

I'm having a bit of an issue uploading files to a database. I'll post snippets of my code below.

The table i'm uploading to has the following structure:


I can upload the file using my MVC application without any errors, however in the database the file stores in CoverFileContent as "0x0000000000000000......". All the other information relating to the file, e.g. MimeType, FileName, CoverID, etc uploads correctly. I took a wild guess that this wasn't correct so I downloaded the file (created a .net MVC file downloader). It seemed to download as the correct type of file, however I when I tried to open it, it told me I could not open it. I'll post some snippets of my code so people can see what I'm doing.





I have inserted breakpoints to debug the code, however coming from more of a business background I'm not sure what I'm supposed to be looking for. It seems that the array is being populated with 00000000s so I'm thinking this is a problem regarding the intake of the file.

[URL] This is the tutorial I was originally following, which I got to work perfectly. However when I rewrote it to suit my own needs (using, etc) this problem seemed to occur.

C# - Sync Database To Uploaded File Using Windows Service Or Website Code?

Sep 10, 2010

I have a website that occasionally needs to have a handful of the tables in its database updated. The updates come from another system that exports to comma delimited text files. I can then either FTP the text files to the web server, send them in through an admin upload page, or manually log in to Remote Desktop to download the text files. I have all my C# code written to parse the files, check the database contents, and decide what to do.

Should I code the sync logic to be part of a file upload page, protected in the admin section of the site or should I create a Windows Service that constantly looks for files to process in a particular directory that I can drop files in through FTP?

I have used Windows Services in the past and they have worked great, but if I ever have to make a change to the code it can take longer than it would if I just had to modify an ASPX.

Are their security benefits one way or another?

Performance benefits?

ASPX page wins the "ease of maintenance" category.

Web Forms :: Storing Remotely Posted Data To Database?

Oct 29, 2010

I am writing an application in which a remote url web site ( says url1 that is sender) sends xml data to another web site (says url2 that is receiver) by using .NET WebRequest. On the receiver url2 if I use .NET Page.Response and .NET Page.Request to store posted/received xml data into an external text file, then the data is stored. However, if I store the received data into database, I do not see the data is stored into the database.

trouble shoot the codes so I can store such remotely posted data into database on the receiver side url2.

I host both url1 site and url2 site in my computer using IIS like [URL]

1/ Receiver page's codes that store remotely posted xml data into database do not work:

protected void Page_Load(object sender, EventArgs e)
Page.Response.ContentType = "text/xml";
StreamReader reader = new StreamReader(Page.Request.InputStream);
String xmlData= reader.ReadToEnd();
ProductNameSapce.ProductCollection.InsertReceivedProduct(xmlData).ToString(); // data is not stored ; the method is tested and works well with hard-coded data

2/ The version of the receiver page at url2 that stores into an external text file works:

protected void Page_Load(object sender, EventArgs e)
Page.Response.ContentType = "text/xml";
StreamReader reader = new StreamReader ( Page.Request.InputStream );
String xmlData= reader.ReadToEnd ();
StreamWriter s;
s= File.CreateText ( Server.MapPath(".")+@""+ Guid.NewGuid () + ".txt" );
s.WriteLine ( xmlData); // data is stored in an external text file
s.Close ();
