C# - Retrieve "Last Modified Date" Of Uploaded File?
Mar 3, 2011
I am developing a website, in which client uploads some document files like doc, docx, htm, html, txt, pdf etc. I want to retrieve last modified date of an uploaded file. I have created one handler(.ashx) which does the job of saving the files.
Following is the code:
HttpPostedFile file = context.Request.Files[i];
string fileName = file.FileName;
file.SaveAs(Path.Combine(uploadPath, filename));
As you can see, its very simple to save the file using file.SaveAs() method. But this HttpPostedFile class is not exposing any property to retrieve last modified date of file.
how to retrieve last modified date of file before saving it to hard disk?

I am using ASP.NET and C#.
I have made a document uploading page, In which use can upload their document. I am saving three fields in the database,
Document Name [NVarchar]
File [Image]
DocumentType [NVarchar]
Now, I am able to add records in the database, successfully. Now I want to show it in the gridview, like DocumentName, DocumentType and a link to download the file.
I have tried by retrieving the records and assigning them to the gridview but I am getting only two columns.

Is it possible to download a file and set its Date Modified attribute by means of Ajax? I tried to use server-side code below but couldn't set Date Modified although I explicitly used "Last-Modified" Response header:
try{
Response.Clear();
Response.AppendHeader("Content-Disposition", "attachment; filename="+l_attchmntFileSpec);
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Last-Modified", "Tue, 15 Nov 2010 12:45:26 GMT");
Response.BinaryWrite(l_attchmntToDownload);
Response.End();
}
catch (Exception Ex)
{ ...
}
Note: The file in question is stored in my database. It is represented by byte array l_attchmntToDownload.

I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview.
I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows).
If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that. Example Filename: DailySalesReport-1-15-2010. My only hangup with this is how do I sort on date, when it's a string value? Convert to date? How would I sort the whole dataset based on this converted value?

I'm trying to access the innerHTML of a span tag modified by jQuery using C#. This is my first project shunning the AJAX libs in favor of jQuery, so I'm not sure how I can get the codebehind to recognize the manipulated innerHTML. I've set all the spans I want to tap into with runat="server", but all I pull are the values I've set when the page was designed.
What steps should I be taking to enable communication between the client-side and my codebehind, and am I even using the best practice here?

I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:
$("#MyList_btnAddAll").click(function(e) {
e.preventDefault();
$('#MyList_lstAll option').appendTo('#MyList_lstSelected');
});
The code has two ListBoxes in fact, one a "source" and the other a "destination". As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected. These are rendered in the browser as <select> elements, as you'd expect.
The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback.
I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data? But in the codebehind after postback the ListBox contents haven't changed. Does anyone know what might be going on and what I can do about it?

I am using an instance of DirectoryInfo to browse and retrive the files and some file attributes on a physical directory. This is displayed in a html table. But if you have for example text files (.txt) or word dokuments (.docx) How can I display the correct icon that is associated with the file in my html table? And further on how can I reach the user who modified the file the last time? Where is that info saved?
Is the DirectoryInfo the object I should use for this purpose? or are there other objects or functions that I should looking at?

I recently purchased the source code of an existing DotNetNuke module in order to make a few modifications. The source of the module contains various .ascx, ascx.resx and .ascx.vb files. as well as a main.dll file. Lets call them:
myfile.ascx
myfile.ascx.resx
myfile.ascx.vb
myfile.dll
I'm using Visual Studio 2008 PRO.
I've made a few changes to "myfile.ascx.vb". When I rebuild "my_module" via Build --> Rebuild my_module, I get confirmation that there are no errors in the Error List. I then upload a fresh copy of "mydll.dll" from the "/obj/release/" folder on my local machine up to the "/bin/" folder on my DotNetNuke site.
The issue that I'm having is that the changes that I made to "myfile.ascx.vb" are not appearing on my DotNetNuke site. Are there additional files that need to uploaded? I've checked timestamps on all of my local files and the only files that are updated after the build is "mydll.dll".

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).

How it's possible create a link to this file (or what is another solution) on the web page if my website is in completely different place!?

I need to create a custom web control which will be a part of a class library. This custom web control implements the upload functionality. I have implemented this with a web user control where I have a fixed path to a page in the web project where the upload of files take place and it works just fine.
The created control in this class library is used in the web project. How do I post the uploaded file to a page, say SomeClass.cs, in the class library.

I am using datetime.now in vb.net to retrieve the current time and date. I passed this parameter into this dim strDate as datetime
strDate = datetime.now
I then saved this strDate into database. However, when I want to retrieve the following date with example, say 2/8/2010 3:58:58 PM
SELECT * FROM CUST WHERE DATE = '2/8/2010 3:58:58 PM'
the result is 0. So i went to SELECT * FROM CUST and realized that the date in the Date column is this:
2010-08-04 15:58:20.000
I have retrieve today's date and saved into database, by right the format should be the same.. May I know what has happened?
