Hi all
I encounter a problem but don't know how to solve it.
Here is my situtation:
I have a web page, 2 user controls: A and B. A and B are dynamically loaded
into the main page. In B there are 4 buttons, TextBox, object and
classes,...Ther e is one object I want to save all of its values and I
decided to use
Session["utility"] = myobject. For the first 3 button, I always remember to
assign that object back to the Session for the next use, and it works fine
for the first 3 buttons. The last button is a "Save All" button and I also
want to retrive that object by: myojbect =
(myclasstypeher e)Session["utility"]. It breaks my code. Running debug I
receive this: myobjec is null and there is a message like this:"
Session["utility"] function 'Session.get_It em' evaluated and returned null
".
I don't know why it gave me that error. I works with 3 other buttons but not
with this.
Thanks for any help 2 1256
Apparently, when you are assigning myObject to Session["utility"], it is not
initialized, and is null. Either that, or the Session data is being lost
somehow (not likely).

When I debugged, that object apprantely had a value. I don't know why after
postback it seemed the Session was swept out
Appreciate any suggestions
Thanks

We have a method that executes an arbitrary batch file (we use it for remote
upgrades of our system).
When we execute this method from outside of ASP.NET (either in the
foreground app or from a windows service), the method works fine. However,
when we execute it from ASP.NET, the execution fails on some machines. Now,
if instead of running the batch file directly, I run cmd.exe and have it run

Hi folks,
Could you shed some light on this issue?
my program is running on Freebsd as a daemon. When user sends a
request, it forks itself and lets its child process handles the
request.
And its main role is just to read a big xml file and save each object
into its embedded DB(such as gdbm).

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.
