CString - string / BOOL - bool
Hans-Peter Haberlandner
Is there any simple strategie when to use MFC or STL? Are there any
changes in 6.0 eg. support to convert CString to string and vice versa?
Thanx
Hans-Peter

If it's an MFC class, stick with MFC types (though some of the STD containers
are more powerful and might be used in place of the MFC variety). If it's a
class that could be used in non-MFC projects, don't use the MFC types.

Why would there be?
CString cstr;
string str;
cstr = "Hello";
str = cstr; // assuming non-unicode
str += " World";
cstr = str.c_str();
What would be simpler then the above?

In general you should use CString within an mfc app. You can, if you
absolutely need to, subclass CString and add your own functions (you will
have to define a few conversion operators though). I use string and
_bstr.... in all our atl projects.
"bool" is another story. I personally prefer to use bool instead of BOOL
except for members that need to be serialized.
The collection classes are a different story. I have used the MFC classes in
our larger projects (450 classes + libs right now) because of the built in
serialization support. Today I would go with stl and add a few helpers for
serialization and other common stuff.
CString to string should be pretty automatic (just assign it, maybe you need
a GetBuffer).
