FriendFeedMaking intellisense acknowledge variables declared inside macros

The simplest way of avoiding that problem is using Intellisense's own disadvantages to our advantage. Take for example the following MFC custom interface implementation code:
HRESULT CSomeClass::XSomeInterface::SomeMethod(long SomeParam)
{
METHOD_PROLOGUE(CSomeClass,SomeInterface);
// If I were to write pThis-> now, I would
//not get the expected drop down list of members.
}
To solve this, we will actually define the variable, only make the compiler ignore it:
HRESULT CSomeClass::XSomeInterface::SomeMethod(long SomeParam)
{
METHOD_PROLOGUE(CSomeClass,SomeInterface);
#ifdef SOMETHING_WHICH_IS_NOT_DEFINED
CSomeClass* pThis;
#endif
// If I were to write pThis-> now, the list would
// pop-up and give me the list of members. Problem solved.
}
Now, this will make your code a little less readable, and is a drag to write
each time. Instead, we can do the same thing to define something that
intellisense will recognize as a "global variable":
In your implementation code, at it's beginning, repeat that same #ifdef sequence.
#include "this.h" #include "and_that.h" #ifdef SOMETHING_WHICH_IS_NOT_DEFINED CSomeClass* pThis; #endifNow, in your method implementation:
HRESULT CSomeClass::XSomeInterface::SomeMethod(long SomeParam)
{
METHOD_PROLOGUE(CSomeClass,SomeInterface);
// If I were to write pThis-> now, I would
// get the expected drop down list of members without
// "declaring" that variable again and again.
}
Note: The example given here was about MFC's implementation of custom
interfaces, however, it's true for every place you have macros defining
variables. The global method, when not applied correctly, will yield
unexpected intellisense behavior.

Alternative to Intelisense

This is probably not very relevant to many people, however any of you out there who are annoyed with the limitations of intellisence may be interested to know that there is an alternative that is pretty damn good. www.wholetomato.com have a product that replaces all of intellisence's functionalitly and adds a great deal more. Including macro parameters and function definitions from any library that your project is using not just the standard ones. Needs a pretty fast PC to run it without irritating delays but well worth it for Lazy people. Not sure as to the price.
I know I can't spell intellisen(c/s)e proberly, or anything else so don't bother telling me.
Cheers

Despite that other guys (rude) comments, I found this tip quite useful. I am using smart pointers and now I can finally get IntelliSense to give me the proper tooltips on them!

"The time-saving technology of intellisense is a real bonus for all of us who use variables with a little more meaning to their names than m_nOad."
Yeah. Intellisense is of absolutely no use to those of us who like to know the scope and type of our variables is. Thanks for the lesson in coding style... appreciated.
