Hi all,
As I change web.config file, all the session variables will be flushed. I want to redirect user on the change of web.config to a pre-defined page. Where can I detect the change in web.config file in my ASP.NET 2005 web application?
Any suggestion is appreciated. Thanks in advance.

In fact when the web.config changes, the entire web application restarts and so will every seperate session. You can handle the session_start event, and redirect users to e certain page when the session starts, or detect session existance on seperate pages and redirect them from there when the session does not exist.

Actually when web.config changes all the session variables will expires and my application generates exception at the time of checking any of the Session variable. The main problem is the Exception which is caused by web.config change. So how and where am I able to detect this Session related exception in the application?

you can check if a session exists. I think your checking for a value or something, but the value of the session appears to be null because the session doesn't exist anymore...
<br />
if ((page.Session["YourSession"] != null)<br />
&& (page.Session["YourSession"] == "RequiredValue"))<br />
DoSomething();<br />
else<br />
Response.Redirect("DefaultSessionDoesNotExistPage.aspx");<br />

Why don't you just use a custom error page? This will do all the redirect stuff for you?

Problem: I am not able to put message into Queue If I am accessing the application from an URL instead of running the application from IDE.
----------------------------------------------------
General Information
1. Visual Studio 2005, Framework 2.0
2. WMQ 5.3 trial version
When we run our application from dot net IDE then we are able to put message into Queue, but if we access the application from an URL then we are not able to put the message to Queue.
The information fromt the event viewer is
--------------------------------------------
Entity 'aspnet' has insufficient authority to access object 'T2RQM'.
The specified entity is not authorized to access the required object. The following requested permissions are unauthorized: connect
Ensure that the correct level of authority has been set for this entity against the required object, or ensure that the entity is a member of a privileged group.
------------------------------
I added the aspnet account to both Administrator and MQM groups, still its not working. One thing which I noticed is that it is working fine in system where Visual Studio 2005 is not installed
|

Anybody is having any idea about it?
The sytem where Visual Studio 2005 is not installed are Windows 2003 system and others are XP

some pepole say with me
Response.OutputStream but it will delete all my control in my pape
so i want give byte[] to System.Web.UI.WebControls.Image
some body help me

You can not include the image data in the same response as the page itself. You either have to save the data to a file, or use a proxy page that acts as a saved file by getting the data from the database and sending it as response.

HI
If you want to get the image from the database which is in the bytes and want to show on aspx page in image control ok
then you can do that what you have to do is first get the image from the database and store it in some temporary folder with extension jpg for that you have to do some conversion look at the code below
System.Drawing.Image newImage;
SqlConnection conn = null;
SqlCommand cmd = null;
DataSet ds = new DataSet();
SqlParameter UserNamedb = null;
SqlParameter AlbumNamedb = null;
conn = new SqlConnection(ConnectionString);
conn.Open();
cmd = new SqlCommand("GetAlbum", conn);
cmd.CommandType = CommandType.StoredProcedure;
UserNamedb = new SqlParameter("@UserName", SqlDbType.VarChar);
UserNamedb.Value = "SandeepAkhare";
cmd.Parameters.Add(UserNamedb);
AlbumNamedb = new SqlParameter("@AlbumName", SqlDbType.VarChar);
AlbumNamedb.Value = "ccccccccccccc";
cmd.Parameters.Add(AlbumNamedb);
SqlDataAdapter ad = new SqlDataAdapter(cmd);
ad.Fill(ds);
conn.Close();
string path = @"c:\AlbumFromdatabase" + "\\" + "SandeepAkhare";
Directory.CreateDirectory(path);
foreach (DataRow dr in ds.Tables[0].Rows)
{
Byte[] imageData = (byte[])dr[0];
string FilaName = dr[1].ToString();
using (MemoryStream ms = new MemoryStream(imageData, 0, imageData.Length))
{
ms.Write(imageData, 0, imageData.Length);
// newImage = Image.FromStream(ms, true);
Bitmap bm = new Bitmap(new MemoryStream(imageData));
newImage = bm;
newImage.Save(path + "\\" + FilaName);
}
}

validation contrlos are predefined.genrally works on text boxes.it is not possible as per user by validation controls.if u realy want to validate u have to write seperate logic for that.by using script lagu..

I did it...
var ucName = "UcPayToAccountant1_";
function jsValidate()
{
if ( checkAmount() && checkDone() )
{
Page_ClientValidate();
return true;
}
else
{
return false;
}
} // End Function
function checkAmount()
{
var amount = document.getElementById(ucName + "txtAmount").value;
if ( isNaN(amount) )
{
return false;
}
else
{
return true;
}
} // End Function
function checkDone()
{
var done = document.getElementById(ucName + "chkDone");
if (done.checked)
{
return true;
}
else
{
return false;
}
} // End Function
added the onclick attribute the button
so using Page_ClientValidate(); function which the validator generates solved the probelm
Best Regards

When you fill DropDownList fill it inside Page_Load event use !Page.IsPostBack
example
<br />
if (!Page.IsPostBack)<br />
{<br />
}

Yes I am filling the list only in Page_Load under!(IsPostBack). My Code:
if (!(IsPostBack))
{
ddlEmpName.DataSource = loadEmployee;//loadEmployee-DataSet
ddlEmpName.DataTextField = "EmpName";
ddlEmpName.DataValueField = "EmpName";
ddlEmpName.DataBind();
}
