i was able to get it to work, but i think there is a problem havingtwo different datareaders whiles within another. after moving it outof the outer while in a method it works. The Exception from the 1st update was because i didn't closed the reader, so it opened too many tables an JET crashed on the 2048 open tables. So but i'm not very pleased with the result, but at least the data comes out

How can I continue to the next row in the foreach loop below.
[code]....
Although Enable Edit and Continue is checked on the Web tab of my ASP.Net MVC 2 project, I cannot in fact change the source code while running. For example, if I try to edit a controller while paused in the debugger, I cannot change the file (acts as if read only).
I found a related post Edit and continue in ASP.NET web projects, however
The answers seem to suggest I should be able to at least edit the code, then reload the page to see the result.I don't know what the distinction is between a Web Application and Web Site projects
Can somebody show me a better approach of looping through a Try -Catch statement. I have something like this:
Try
dbConn.Open()
Catch ex As Exception
errmsg = ex.Message
End Try
I need to try to connect 5 times before logging an error. My first thought was to nest Try - Catch 5 levels but I didn't like that idea. I'm sure there is better solution to it.
I am developing a intranet site and want to track the users, I am using session for this purpose, I am using windows authentication mode so there is no login form here. When a user clicks the url for the first time a new session is created and at that time I am adding a entry in a table(say :Users) with username and logintime and sessionid etc. Below is the logic Iam using in form_load event of Default.aspx
If session("user") is nothing then
---create new session (at this point I am adding a entry in table(users))
Else --- use the same session and continue the work.
End if
When I check the users info in the table some entries are created with same userid and same sessionids with different login time, how this is possible. I just want to know who is logged in and what time.
Here is the code copied from [URL] In asp.net code behind, I use try-catch try to catch any error but never catch it. In SQL database, if I rename Employees to Employeesx or change column DepartmentID to DepartmentIDx, record will not be deleted (it is right) without any error (it is wrong, suppose catch an error).
CREATE PROCEDURE DeleteDepartment
(
@DepartmentID int
)
AS
BEGIN TRANSACTION
DELETE FROM Employees
WHERE DepartmentID = @DepartmentID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RAISERROR ('Error', 16, 1)
RETURN
END
DELETE FROM Departments
WHERE DepartmentID = @DepartmentID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RAISERROR ('Error', 16, 1)
RETURN
END

I have try{}catch(Exception ex){} in the right place:
Code:
protected void Button1_Click(object sender, EventArgs e)
{
try
{
// all processing occurs inside here
}
catch(Exception ex)
{
}
}
I even created a global.asax file and on the Application_Error event, I wrote a code that would email me the error (and i'm not getting an email regarding that error when I get the error shown above). I know for a fact that the thread is going inside the "try" statement because I send emails to myself whenever it finishes certain codes inside of it. So how come I'm getting that error in my browser instead of it being handled in my "catch" statement? I have two problems here, one, why is the exception not going to my "catch" statement, and two, why am I getting that error in the first place.
Note: my web app calls a webservice.
Im stuck with declaring a string which is in a loop within another loop.
Dim CompanyDetails As String = ""
Dim CompanyRow As DataRow
For Each CompanyRow In newdt.Rows
CompanyDetails += CompanyRow(1) & " " & CompanyRow(0) & "<br/>"...
How can I get this to see the GetInfo as declared..... since its in a loop within a loop?

I am completely stuck here. Basically, I am serving a file to the user by sending it using Respnse.BinaryWrite. I am also sending this on a redirected page so as not to destroy the Response stream of the webpage which fired the filedownload. This works perfect on my development machine, it also works perfect on Firefox.However, if I publish to my test server, on IE 8 (and 7 I presume) a security warning bar appears (does not appear in dev mode on my pc), asking the user to accept or decline the file. Now the not-so-funny thing: If the user accepts, the file is NOT served, I just get back to my main webpage. If the user tries a second time to get the file the security question will NOT pop up again and the file is served.How can I make sure the file is served in the first instance if the user accepts the security warning and wants to download?
Code used:
HttpContext.Current.Response.Clear()
HttpContext.Current.Response.AppendHeader("Content-Disposition", String.Format("attachment; filename={0}", Session("FileName")))
HttpContext.Current.Response.AppendHeader("Content-Length", myReportData.Length.ToString())
HttpContext.Current.Response.ContentType = "application/pdf"
HttpContext.Current.Response.BinaryWrite(myReportData.ToArray)
HttpContext.Current.Response.Flush()
HttpContext.Current.Response.End()

View 1 RepliesI had written a piece of code in MVC 1.0 and the Response.Redirect worked flawlessly.I now have a new application and I decided to use MVC 2.0 but that same piece of code is now not working. After the Response.Redirect is called, the code STILL continues to execute. I have not seen this in any version of ASP.NET until now. Usually, after Response.Redirect is called, execution of all code is stopped.
Why is this now happening and how do I fix this? this is very frustrating to me and I cannot seem to find a solution.
Right now I have an error if f.ParentID is null:

TreeItemRows = (from f

where (f.ParentID == TreeItemId)
