ThreadAbortExce ption Question

[Burak Gunay]

Hello,

I have a piece of code where I am writing the contents of a datagrid to
an excel report

Dim tw As New StringWriter()
Dim hw As New System.Web.UI.H tmlTextWriter(t w)
Dim frm As HtmlForm = New HtmlForm()
Response.Conten tType = "applicatio n/vnd.ms-excel"
Response.AddHea der("content-disposition",
"attachment;fil ename=Test.xls" )
Response.Charse t = ""
EnableViewState = False
Controls.Add(fr m)
frm.Controls.Ad d(grid2)
frm.RenderContr ol(hw)

Response.Write( tw.ToString())
Response.End()

it works fine.

In debug mode, after I closed down the excel report and exited the
program, I saw the following message in the debug window

"A first chance exception of type
'System.Threadi ng.ThreadAbortE xception' occurred in mscorlib.dll
An exception of type 'System.Threadi ng.ThreadAbortE xception' occurred
in mscorlib.dll but was not handled in user code
The program '[1368] WebDev.WebServe r.EXE: Managed' has exited with code
0 (0x0)."

I looked at msdn

http://msdn.microsoft.com/library/?u...classtopic.asp
and put a try-catch block around the code to ctach ThreadAbortExce ption
but this time it came back with a "page can not have 2 forms error".

The program works fine. Is this a serious issue? Do I need to catch
this exception? It seems like catching it actually mad ethings worse.

Thanks,

Burak

Response.End() intentionally throws a ThreadAbortExce ption - it's actually
how it works.
