Hi all,
I want to write a schema file to validate my xml file, and
encounter a problem as follow.
the xml file contains a <pathnode£¬whos e value should be a string not
included by a blanklist(for instance, {"/bin", "/root", "/usr"}), how
to define a "blanklist" type use simpleType to
implement this, or any other advices?
Thanks !! 3  1824 
Enumeration won't do it, since you want to enumerate the forbidden
values. You might be able to get this via regular expressions... or it
might make more sense to just check it in the application rather than in
the schema. Given your examples, I suspect that this may actually wind
up wanting to be decided on a per-installation or per-user basis, which
would be another reason to keep it in the application rather than the
schema.

thanks for your reply.
Using regular expressions to describe such a "blacklist" is too hard.
Actually, I use an xml as the configure file of my application,
the configuration validation and the configuration loading are
seprated,
so i must do the restriction at the stage of configuration validation.

The only alternative I can think of is application code. I'd love to be
wrong about that. Good luck...

I'm working on a system which exposes TCL scripting but looks to be
difficult to extend with a native binary. I need to build a "front end" for
it that has lots of complicated data structures and can benefit from strong
typing, so C++ is a more natural choice for implementation. Does there
exist a C++ compiler that generates TCL as its output?

Hi,
Turns out it's possible to spoof another type with Object.GetType
method. If you do this:

class C {
public new Type GetType() {
return (String.Empty.GetType());

I have a page the uses a form to pass a postcode to another page and I
want to test it against an SQL Injection. What would be a safe (i.e NO
DELETING of data ) statement to try and how would I format this to try
in the form.
I have limited the field to 10 chars so I know i would have to test it
with a larger field because a hacker could just rewrite the form and
use a lerger field for the attempted attack.
Many thanks in advance

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.
Here is my compilation command:
