I have a little problem.
I designed a webpage (VB.Net) with code behind "Page_Load" .
If the process works fine, the page is shown.
If the process raises an exception, I catch it and modify a label
inside the page (red color, ...)
But, the page is not displayed. I only have a blank screen.
No error page, no nothing.. just stops.
Do you know this problem ? The solution ?
Thanks

No, the page contains the <html><head><bo dy> ... </html>
The generated page is ok but empty.
I'm handling files (file.move, file.delete), when I was working on dos
programs (long time ago), there were specific problems when working on
files. Maybe it's a recurrent problem ?
try posting the part of the code that generate error..
possibly there is an error in the exception handler(?).. you may want to
try commenting every thing in side the catch {} and keep a simple
"Response.Write ("error")) ...
Also how is the customErrors configureed in web.config ?
<customErrors
mode="RemoteOnl y"
/>

files. Maybe it's a recurrent problem ?
First in the web.config I have <customErrors mode="Off" />
If I comment in the catch and only leave the response.write( "ERROR"),
then it's displayed.
If I remove the Throw (the one with a comment in the code) in the
catch, it's the same thing.
It seems that if I make a fileCopy with wrong file name, the page is
not displayed. here's my web page :

I am in the process of setting up a base page model for multiple reasons.
One of the reasons is so that I can catch all exceptions when derived pages
throw/raise them. I don't want to use the standard OnError virtual method to
handle this requirement because the form does not complete its rendering
process when this occurs. I really need the form to display properly on the
screen.
I have managed to catch nearly all exceptions by...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
