Hi everybody.
I don't know if this is possible, but I am looking for a way to
automatically inject code.
I would like to fire a Debug.Writeline () automatically when a method is
invoked and when the method exists.
Anybody knows if this is at all possible? Or is any other variant possible ?
Is custom attributes a way to go?
Basically I want a similar behaviour as ServicedCompone nt class with its
[Autocomplete] attribute:
It does one thing if all goes well and another thing if exceptions occurs?
Any ideas anybody...
thank anyway!

Bobben,
Basically, you are looking for something like Aspect Oriented
Programming. While AOP offers you other ways to weave aspects, the basic
mechanism that you are looking for is method interception. .NET does offer
something like this, using Context-bound objects. However, there is a price
to pay for it.
A good article to read on this is on MSDN, titled "Decouple Components
by Injecting Custom Services into Your Object's Interception Chain", located
at (watch for line wrap): http://msdn.microsoft.com/msdnmag/is...T/default.aspx
It will show you how to do exactly what you want.
Hope this helps.

Yep. Something like, but more general, called Program Transformations ,
which replace specified source patterns with others source patterns.
In Bobben's case, he wants to replace the method head with the
same method head and added instrumentation . See http://www.semanticdesigns.com/Produ...ransformations
for more information on this.
See http://www.semanticdesigns.com/Products/TestCoverage for a whitepaper
showing exactly how to use program transformations to insert instrumentation
probes just like this.

I have been reading a little that you should secure your PHP code to
prevent SQL injection into a database (MySQL in my instance), mainly by
checking the type of data to be put into a database, and if text, to
addslashes() the data.
What I have not managed to find out, is does SQL injection threaten the
input of data into a database, ie a guestbook, or the reading of a database

Hi All,
Does anyone know how to clean a asp application from a
virus that converts labels with the word 'Insurance' into
link button to a web page. It also injects text in the
textbox when the textbox.text has any reference to
this 'insurance' word.
I am using custom controls on custom page. This injection
seems to be occurring after the pre-render event.

Thanks.. Since my last post, I have identified a few more
facts on this case.
This code injection occurs in the client browser. The Web
server seems to be sending correct page. So far, I have
identified just one user machine that seems to be infected.
Even in the client machine, if we look at the html source
code, this injection code does not exist. If this is true
than I have no way of knowing how the page is getting

I was reading the code of FFmpeg and it seems that they use malloc
just too much. The problems and dangers of malloc are widely known.
Malloc also has some overhead (although I don't know what is the
overhead of automatic variable sized arrays, I suspect it is smaller
than that of malloc), although I'm not too worried about it.
I was thinking that, with C99's variable length arrays, malloc
shouldn't be needed most of the time. But I'm...

Hi,
is there a way to avoid the automatic copy constructor generation. I do
not want the object to be non-copyable. I simply do not want that
copying is done by the default copy constructor. But there is a
constructor that accepts the base class. This one should be used for
copying.
In fact i have a set of classes with a common abstract base. The
implementations do not have own data members. They only implement

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.
