COM Callable Wrapper(CCW) - In simple terms -CCW is the special wrapper
created over your .Net classes so that they appear as COM objects to other
COM components... If your .Net application needs to be called by other COM
components you need to make sure that CCW is created over your .Net
classes...
Runtime Callable Wrapper (RCW) - In simple terms - RCW is a special wrapper
created over COM components so that they appear as .Net components to other
.Net components... If your .Net components call other COM components then
you need to make sure that RCW is created over the COM components that your
application calls...
PS: I will be shifting to Milwaukee, WI tomorrow... Till I get my new home
set up, I might not be having any access to internet so probably would not
be able to send in Tips for a while... I apologize in advance for the same
and will try to get back to grove ASAP...
Tip Of Yesterday
Maintaining State Across ASP.Net Pages - Continued 4
Due to the weekend you might have lost touch... In that case do browse
through the previous tips on the blog site... The current mail is in
continuation of previous tips...
There is a possibility of InvalidCastException, which may come in case of
using properties with Server.Transfer... If you think for a while you can
very easily conclude the possible causes...
1.) SecondPage is called from a page other than the FirstPage
2.) SecondPage is directly loaded
3.) SecondPage is called from any other page using response.redirect
In such a scenario do make sure that you catch this exception and ignore
it...
PS: You know Blogspot has provided search facility for the blogs... So now
if you want to search some specific tip in my blog you can use that search
facility and you will get the tip right over there... :-)
