But, I also need to store the last modified date of the file in the database as well. How would I accomplish this?

View 1 RepliesIs 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?

How can I get the file creation date of the file used in the FileUpload control?
View 3 RepliesI 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?

View 1 RepliesI 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 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 have a FileUpload control from where I want to select the chosen file from my code behind, bu when I try for example myFileUpload.PostedFile it always says that there is no file selected in that FileUpload event though I browsed after a file. Why is this?

How can I retrieve file information (size of file) before it is uploaded to the webserver?
I would like to create a multi file upload. I have it working in JQuery but I would like to know the size of the files to set a limition by summing up the total the file sizes together.
How to set default file in <asp:FileUpload />
When a FileUpload is null then i want to set defualt file .
regarding my code :
Byte[] imgByte = null;
if (FileUpload1.HasFile && FileUpload1.PostedFile != null)
{
HttpPostedFile File = FileUpload1.PostedFile;
imgByte = new Byte[File.ContentLength];
File.InputStream.Read(imgByte, 0, File.ContentLength);
}
The requirement is that the whole original file path be saved to the database; for example: L:folder1folder2xyz.doc. However; the FileName property of the FileUpload control will only give "xyz.doc". We are interested in obtaining the full path only and really not interested in using the control to do any upload.
Is there any way to get the full path? We would like our user to be able to browse to the target file instead typing into a textbox because the folder name could be very long and several levels deep in our organization.
