Why do you need to do this??
For your session check, you can use your existing class and I suggest you should pass the Session object to your session checker function and then check the sessions and proceed to redirection. Like
<br />
public CheckAuthentication(System.Web.SessionState.HttpSessionState oSession ) <br />
{ if ( oSession["login"] == null )<br />
Response.Redirect("expired.aspx"); }<br />
Also pass the response object the same way.
NOTE: Remove the inheritance from your class

Thanks, I need to do this because, this simplifies my job than passing Response, and SessionState object to Checking functions. In all my pages I need to check this session. So i thought it's better to go for inheritance method. May be that is a bad approach, but still it has to work when we think the program flow. Any Idea on what is going wrong here ?

Hi, I have been working on this for over two weeks and its not working. I don't know what else to do since I'm really green at this. I'm trying to display binary data from a database using Response.Write(). Please take a look to see where I went wrong, thank you in advance for your help.
Private Sub ListBox2_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim DBConn As OdbcConnection
Dim DBCommand As OdbcCommand
Dim DS As New DataSet
If Not LBoxProfessions.SelectedItem Is Nothing Then
DBConn = New OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=myDB;Database=myDB;User=myUser;Password=myPW;Option=3;")
DBCommand = New OdbcCommand("Select ResumeID,Resumes,DocType, from tb_content where Professions = '" & LBoxProfessions.SelectedItem.Text & "' Limit 10 Offset 10", DBConn)
DBConn.Open()
Dim AD As OdbcDataReader = DBCOmmand.ExecuteReader()
If (AD.Read()) Then
Dim contentLength As Integer = Convert.ToInt32(AD.GetBytes(0, 0, Nothing, 0, Integer.MaxValue))
Dim buffer As Byte() = New Byte(contentLength - 1) {}
AD.GetBytes(0, 0, buffer, 0, contentLength)
'Resumes is the field in the database table that holds the documents
Response.AddHeader("Content-Disposition", "attachment;filename=Resumes")
'DocType is the field that holds the mime types
Response.ContentType = DirectCast(AD("DocType"), String)
Response.BinaryWrite(buffer)
Response.End()
End If
DBConn.Close()
End If
End Sub

What is your question ? Why don't you look up a column to read your binary data ?

Basically I'm doing what you've suggested last week. First I stored the mime types of each binary file in a field called DocType in my database. So if an image file is stored in the Resumes field it would have a mime type of "image/gif" etc. Then after I connect to the database I use the datareader to read the data then put the data into a byte array. Then I use the following two lines to determine the name of the file to be displayed and to determine its content type.
'Resumes is the field in the database table that holds the documents
Response.AddHeader("Content-Disposition", "attachment;filename=Resumes")
'DocType is the field that holds the mime types
Response.ContentType = DirectCast(AD("DocType"), String)
I have a typo in my code and its "filename=ResType" I've already changed that to Resume. Don't you run away after giving just a vague response Christian 'cause I really need your help lol. When a list item is selected its suppose to show a file but its not working, I'm very frustrated right now. Thanks for replying

Yeah, but when you fille the buffer variable, you don't use a column name to get to the data in question, you just do a read on the row itself.

Hi,
I have made a small application which process Mail Items (Notes Items) and save its properties in database. I have used outlook object model.It is working fine but for one message it gives an error as below.
"Cannot open this item.Out of memory or system resources. Close some windows or programs and try again."
Even this message also can't be open in outlook. I don't want this error comes while processing.So I don't want to process this message from my application. Is there any property of the message from which I can detect that it can't be processed? If any one knows please reply.
Thanks,
Pavan

I'd just create a base control, have a collection of images, and draw them myself.

OK, sorry, I didn't spot that this was the ASP.NET forum. A repeater is the way to do this. You can use a repeater to build a control that builds a table, and that adds the tr tag for a new row after a specific number of images. Of course, they need to exist as files and then you can show them in IMG tags.

Hi Friend,
Thankx for ur reply.
I am not sure, is it Grid view control is available in .NET 1.0??
All I ever wanted is what others have....

Nope. A DataGrid is, but you'd need five images per row to make that work. A repeater is better.

Hi,
I am using Visual studio 2005 and I want database connectivity.
I tried connectin to SQL Server 2005 but was unable to do so. I even tried connectin to MS Acces but was not able to do so.
Please let me know how to connect to database using ASP.NET(C#) 2.0.
Thanks a lot!!
SHWETA!!

You say you tried, what did you try ? There are hundreds of samples online showing how to connect to a DB, we need to know what you tried, and what went wrong, to give you more focused help than you can get from a google search.

I'm guessing that may work if using the default DB on the same machine. Perhaps.

Why is your connection string not in resources ? Why do you create two connection objects in this code ?

OK, so long as you're asking
public SqlConnection con = new SqlConnection();
string connect= "Server=Server_path;Database=ABC;User=userassword=Password";
con = new SqlConnection(connect);
I assume that public means that con is a member variable. Otherwise, it's an error.
You create a new object at the point of declaring the variable.
You assign a string to the connection string, although you don't expose it in any way ( which is not wise )
Then you use this string to create a new connection object ( your second ), meaning that the first one is never used, and if this is a member variable, as it seems to be, it means that you have a member object, but you recreate it, every time you use it.

Also we can use our common sense while declaring the variables.
What i ans for the connectin doesnt mean that this is the exact and only ans for this post, its a Hint of doing.
And one who needs toimplement this can use its little mind according to its need.
For ur graet information i always use this as staic and defined under one class, so every time u have to declare the connection string.
