Hi,
I finished my application butonce again i have some strange behavior
with XML/text functions...
for example, here below is a function which worked perfectly till now
and now generate an error :
"An unhandled exception of type 'System.NullRef erenceException ' occured
in Unknown Module.
Addition information : object reference not set to an instance of object"
when i click on break, i can not get anymore information, but if i click
on continue, my application works perfectly... :-(
this error is raised after few sw.WriteLine commands...
i have the same issue if i do :
dim doc as XMLDocument
doc = new XMLDocument (here occured error)
where could be the problem ?
from my point of view, some options in application could have such
impact but which ones ?

Hi,
I dont know why you are getting the error at the new xmldocument
line. I would use the xmltextwriter class to write the xml document instead
of a streamwriter. http://msdn.microsoft.com/library/de...classtopic.asp

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
