Well it is very simple to create excel files from asp.net code.
The following is the sample code to create one with font and style settings etc.
----------------------------------------------------------------------
//Write a table structure with all formatting you need (e.g. font, etc.)
string strHtml="
strHtml+= ""
strHtml+=""
strHtml+=""
strHtml+="| Name | Color | Formatting | | Ketan | This is Red Color Font | None | | Abc | NA | None | | Xyz | NA | This is bold text |
"
//Clear the Response Headers
Response.Clear();
Response.Charset = String.Empty; // String.Empty();
//Set Content Type and add header
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment; filename=abc.xls;");
this.EnableViewState = false;
System.IO.StringWriter myTextWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter myHtmlTextWriter = new System.Web.UI.HtmlTextWriter(myTextWriter);
HtmlGenericControl gn = new HtmlGenericControl();
gn.InnerHtml=strHtml;
gn.RenderControl( myHtmlTextWriter);
Response.Write(myTextWriter.ToString());
Response.End();
----------------------------------------------------------------------
If you need to embed excel sheet functionality, you need to work out more.

There are a couple of ways to create the Excel document:
+ Use the Automation to create the Excel file, however this option is not recommended at the server side.
+ Create the Excel file in XML format.
+ Use a third party component to generate the Excel file without using Automation.

Just follow the instructions given below
First of all,take datagrid from toolbox and paste it on webform1.aspx
1) Now Use some database to connect to table. Use its connection string.
e.g. Dim con as new sqlconnection
con.ConnectionString="Data Source=servername;Initial Catalog=pubs;User Id=sa;Password=sa;Persist Security Info=False;";
2) dim ds as dataset()
dim cmd as sqlcommand = new SqlCommand()
cmd.Connection=cn
Dim Query As String = "select * from EET_ACCRIGHTS"
'use above code for ref.
Dim MyCommand As SqlDataAdapter
MyCommand = New SqlDataAdapter(Query, con)
DS = New DataSet
MyCommand.Fill(DS, tablename)
3) Now use following code
If con.State = ConnectionState.close Then
con.Open()
End If
datagrid1.datasource=ds.tables(0)
datagrid1.databind()
If con.State = ConnectionState.Open Then
con.Close()
End If

Hello All,
I created a bit map and it is saved to a jpg file. The code is:-
oBitmap.Save("c:\\codes\\gen_img.jpg", ImageFormat.Jpeg);
I want the file to be given by the user(save dialogbox should come and the filename should be given by the user and the location "SHOULD BE" on the server),i.e, i need to get the location as well as the filename from the dialog box and should be given instead of the hard-coded one.
Hope Anyone can find me a Solution for this!
regards,
jeeva

If you mean that the user should upload the file:
Put a FileUpload control in the form. When the file has been uploaded you get it from the PostedFile property of the control.
If you mean that the user should get a dialog to choose a location on the server:
You have to build the dialog yourself in the form of a web page. There is no way that the user can directly access the file system of the server.

in C#?
DateTime dt1 = new DateTime(2001,6,1);<br />
DateTime dt2 = new DateTime(2006,6,11);<br />
<br />
TimeSpan ts = dt2.Subtract(dt1);
The TimeSpan class has propertiessuch as "TotalDays" which will give you the info you want.

hi ,
you can use SQL also to find the difference between two dates.
the code looks like :
DATEDIFF(part of the date,start date,end date)
"part of the date" means whether its day,month or year of a date variable.

I have problem with sending email in asp.net page.
When user register in my page i want to send to user email address directly, if they use Yahoo mail the message send to Bulk mail not Inbox, but other mail is ok, How can i correct it?
................

Hi,
Yahoo is using many filters to check spam.
It depends on your server. It must have a public IP and should not be blocked by the Yahoo.
Make sure about these things.
Thanks

Hi,
Do you have the URLs in a comma seperated string?
If yes, you can split it into a string array and then generate array of hyperlinks as much as string array lentgh of the URLs.
I hope this will help you,
If not, please explain your situation
Thanks,
Sushant Duggal.
