On Button Postback an Aspx Page runs the following onclick C# event handler:
{
..
// dr[“Content”] - DataRow Item type byte[] where is a song in mp3 format
ar = dr[“Content”];
Response.ContentType=“audio/mpeg”;
Response.Clear();
Response.BufferOutput = true;
Response.BinaryWrite(ar);
Response.Flush();
}
I received error in Response.Flush() – The remote host closed the connection.(HttpException).
If I use Response.End() in place of Response.Flush() receive WMPlayer(on the Client) error about there is not codecs for playing sending stream. It possible that sending stream from ASP.Net Page is wrong because on client PC mp3 codecs are installed.
I try to use Response.WriteFile(filename) instead of Response.BinaryWrite(ar) and received the same errors.
Note : I see after Response.BinaryWrite(ar) line , in debugger, Response.OutputStream.Length property is showing a SystemNotSupportedException.
My question:
Can Asp.Net Page send audio to client as other binary content “application/pdf”,”image/gif”, i.e ?
Please help me,
Thanks

The global.asax file in Web App is:
<%@ Application Language="C#" %>
public void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started
}
public void Session_End(object sender, EventArgs e)
{
// Code that runs when a session ends.
}
and mode attribute is set to InProc for SessionState element in Web.config file, and State Management configuration for Asp.Net Site in IIS 6.0 is mode = IProc and Cookieless mode = UsesCookies. The Client is Internet Explorer 6.0.
The Session_Star fires but Session_End does not. Why?
Help me please,
Thanks

Session_End will not fire until Session.Abandon is called in your code.
When the user signs out from the website then make a call to Session.Abandon.
|
|
|
|
|
If you don't call Session.Abandon(), then the Session_End event will fire when the session expires. The default session timeout in IIS is 20 minutes. If you didn't set any other expiration in code, than your event will fire after that time.

Hi,
I have a page that displays data in GridView. The data is obtained from an SQL Server database. One column is an IP addresses, which are stored as VarChar(15) in the database.
The page executes a select statemnet and bind the GridView with the DataTable obtained by executing this SQL statement.
The problem is that I want to allow the user to sort the Grid according to the IPs column.
Taking into consideration, that IP
10.5.0.0 should come before 10.30.0.0 in ascending sorting. So, I can't rely on the built in sorting of the GridView.
Kind regards,
Ahmed

You can always create a computed column that brings the numerical value of the ipaddress then override the SortCommand and specify the computed column as the sort expression
|
|

I was looking forward for something like the Sort function of the System.Array class, to which I can pass a class implementing IComparer. It seems there is no other way than that indianet had posted.
Thanks indianet for your help.

Hello,
how do I validate and debit a credit card? Are there any (web)services for that? I just need a starting point here. Just in case it is important: A German company providing the service would be an advantage!
Thanks in advance!

You need to go through a payment gateway and pass the credit card information to the gateway, and you will get back the authentication confirmation or rejection.
But first you will need to obtained a merchant account from a bank (which deals with CC) or a credit card processing centre. It is subjected to be approved or disapproved by the bank or centre (base on your company, risk of your business etc).

Hi,
I have a multi user application in ASP.NEt (vb.net). I want to put my print operations in a queue so that i can bulk-print at the end of the day. To be specific i have to retrieve the inner html inside a div tag, and then store it in printing queue( can be SQL database,filesystem,or anywhere else). After searching through several engines, i am left with the option to convert the current page to PDF (using 3rd party components), save it in the file system and then execute print at the end of the day.
Do i have any other option besides converting my page to PDF?

The length of the control seems to be double the length of the dates.
How can I reduce the size of the control to be as same as the length of the dates please?
This is how the control is popiulated:
foreach(DataRow rowPayDate in dsPayDates.Tables["Table"].Rows)
{ ddlPayDates.Items.Add(DateTime.Parse(rowPayDate["dtPayDate"].ToString()).ToShortDateString().Trim());
}
