Use HtmlAnchor Tag if you want to download file.
try following code in ItemTemplate
<a href='<%# Eval("fieldName")%>'>Download</a>

hi,
I am using the below coding to thumbnail creation, this coding is saving both the original image and the thumbnail image. I don’t want the original image. How to delete the original image. Please help me.
private void btnUpload_Click(object sender, System.EventArgs e)
{
// Initialize variables
string sSavePath;
string sThumbExtension;
int intThumbWidth;
int intThumbHeight;
// Set constant values
sSavePath = "images/";
sThumbExtension = "_thumb";
intThumbWidth = 160;
intThumbHeight = 120;
// If file field isn’t empty
if (filUpload.PostedFile != null)
{
// Check file size (mustn’t be 0)
HttpPostedFile myFile = filUpload.PostedFile;
int nFileLen = myFile.ContentLength;
if (nFileLen == 0)
{
lblOutput.Text = "No file was uploaded.";
return;
}
// Check file extension (must be JPG)
if (System.IO.Path.GetExtension(myFile.FileName).ToLower() != ".jpg")
{
lblOutput.Text = "The file must have an extension of JPG";
return;
}
// Read file into a data stream
byte[] myData = new Byte[nFileLen];
myFile.InputStream.Read(myData,0,nFileLen);
// Make sure a duplicate file doesn’t exist. If it does, keep on appending an
// incremental numeric until it is unique
string sFilename = System.IO.Path.GetFileName(myFile.FileName);
int file_append = 0;
while (System.IO.File.Exists(Server.MapPath(sSavePath + sFilename)))
{
file_append++;
sFilename = System.IO.Path.GetFileNameWithoutExtension(myFile.FileName)
+ file_append.ToString() + ".jpg";
}
// Save the stream to disk
System.IO.FileStream newFile
= new System.IO.FileStream(Server.MapPath(sSavePath + sFilename),
System.IO.FileMode.Create);
newFile.Write(myData,0, myData.Length);
newFile.Close();
// Check whether the file is really a JPEG by opening it
System.Drawing.Image.GetThumbnailImageAbort myCallBack =
new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);
Bitmap myBitmap;
try
{
myBitmap = new Bitmap(Server.MapPath(sSavePath + sFilename));
// If jpg file is a jpeg, create a thumbnail filename that is unique.
file_append = 0;
string sThumbFile = System.IO.Path.GetFileNameWithoutExtension(myFile.FileName)
+ sThumbExtension + ".jpg";
while (System.IO.File.Exists(Server.MapPath(sSavePath + sThumbFile)))
{
file_append++;
sThumbFile = System.IO.Path.GetFileNameWithoutExtension(myFile.FileName) +
file_append.ToString() + sThumbExtension + ".jpg";
}
// Save thumbnail and output it onto the webpage
System.Drawing.Image myThumbnail
= myBitmap.GetThumbnailImage(intThumbWidth,
intThumbHeight, myCallBack, IntPtr.Zero);
myThumbnail.Save (Server.MapPath(sSavePath + sThumbFile));
imgPicture.ImageUrl = sSavePath + sThumbFile;
// Displaying success information
lblOutput.Text = "File uploaded successfully!";
// Destroy objects
myThumbnail.Dispose();
myBitmap.Dispose();
}
catch (ArgumentException errArgument)
{
// The file wasn't a valid jpg file
lblOutput.Text = "The file wasn't a valid jpg file.";
System.IO.File.Delete(Server.MapPath(sSavePath + sFilename));
}
}
}
public bool ThumbnailCallback()
{
return false;
}

You don't have to delete the file. Just don't create it.
Create a MemoryStream object from the byte array, and load the image from that.
jai 123 wrote: myFile.InputStream.Read(myData,0,nFileLen);
That's not a secure way to read the data. The Read method returns an integer that tells you how many bytes where actually read, and this can be less than the number of bytes requested. You have to loop until you have read all bytes, or until the value returned is zero.

Error Reports r like:
---------------------------------------------------------------------------------
Server Error in '/fotoAlumamit/bk' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customerrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customerrors> tag should then have its "mode" attribute set to "Off".
<configuration>
<system.web>
<customerrors mode="Off">
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customerrors> configuration tag to point to a custom error page URL.
<configuration>
<system.web>
<customerrors mode="RemoteOnly" defaultredirect="mycustompage.htm">
-------------------------------------------------------------------------------

Append http to the links present in that secure page instead of redirecting like /page.aspx

You are using relative url i.e. "..\otherpages.asp" so after you visit the https page other consequent pages will be assumed to be of the same protocol will be used last (https).
Use absolute url (e.g. "http://www.codeproject.com/otherpage.asp" ) on the links of other pages.

I wanted to know what kind of database would help me around for building a website which includes search. I will be using ASP.NET for my website and i am not sure what are the parameters which needs consideration before selecting a database.

SQL Server is Microsoft's Database solution to medium to large and Enterprise level project's. I suggest anyone to use this for a ASP.NET website.
niting85 wrote: what are the parameters which needs consideration before selecting a database.
I guess this depends on the size of the project, Project requirement's, resource availability, cost and other technical factor's such as Whether Database server provides a GUI tool for Database Designing, Does it provides high Security System, and Does it provides extensive sql library functions, Referential Integrity, Triggers, Cursors, Views....

SQL Server works pretty well, a good point is that you can perform search as well on embedded Word / PDF documents.
Mmm... do you want a search on your DB, or a search in your site? If it's a search in your site you can think about using msn or google search (you can customize to search in your site), if it's an intranet another possibility is to use Sharepoint 2007 indexing capabilities (don't need to develop your site using sharepoint  ), take a look at:

Your server is not allowed to relay messages that are not (either from one of it's users or to one of it's user's inbox)
So to send the message either the sender or the receiver has to be from the server's (i.e. me@myserver.com)
Nothing wrong with your code. Just the test email addresses need to be reviewed.
