This works on my locahost, but not on a remote server?

Hello. This problem is perplexing me.

I have a asp:button which runs a javascript function when it is clicked. It
returns a true or false depending if a postback is needed. This works great
when I run it on my development pc. But, when I run it from another
computer, it ALWAYS does a postback, even if it returns false. I have no
ideas why??

The plot thickens... I don't know if this really matters or not, but this
button is in a datagrid.

Can anyone explain to me why the javascript function posts back??? The
code is posted below.

Thank you in advance!

Thread aborted when doing HttpContext.Current.Response.End

Hi,
I have written a function to export the datagrid data to excel. In that
function I was calling HttpContext.Current.Response.End() at the end. If I a
m
doing this, I am getting an exception message "Thread was being aborted". If
I don't do this then it is exporting the whole data instead of just the
datagrid. I am not knowing what might be the problem. Please let me know if
you have any idea
Thnx,
Sridhar.That's just how Response.End() works, it throws a ThreadAbortExxception.
You can't doing anything wrong, but you may. You'll either need to handle
(catch/swallow/hide) the exception or change your page so only the grid
shows and there's no need to End the request.

Thread safety issue

In my VB.Net ASP project, I have a function in a module (same thing as a
static function in C#'s terms) that is shared by all the sessions. What is
does once called is to write messages into a common log file that's also
shared by all the sessions. To make sure it is thread safe, I use the Monitor
class to sync it up. Here is the simplified version of that function"

Public Sub WriteLog(ByVal strMsg As String)
Dim oWriter As StreamWriter
Dim strLogPath As String = "C:\Logs\test.log"

If Not File.Exists(strLogPath) Then
oWriter = File.CreateText(strLogPath)
Else
oWriter = File.AppendText(strLogPath)
End If

Monitor.Enter(oWriter)
Try
oWriter.WriteLine(strMsg)
oWriter.Flush()
oWriter.Close()
Finally
Monitor.Exit(oWriter)
End Try
End Sub

My problem is that this code doesn't seem to do what I want it to do. I am
still getting error that says "The process cannot access the file
'C:\Logs\test.log' because it is used by another process.". Why is this
happening? I must be doing something wrong. Can some one tell me how I should
do this?

Thanks a million!

Fengthe object you are locking on is local to the call, so threads do not block
each other because they are all locking different objects.

you need to lock on a static object. you could use the class type, but there
is a performance hit for this, better to create an actual object to lock on.
also the File.Exists need to be in lock.
