1. I think you mean if the exception object is allocated on heap, it should be safe to address it later;

And if in your previous sample, it is local object, we are not safe to address it later.

class Foo {
public:
	Foo(int input)
	{
		this->a = input;
		cout << this << endl;
	}

	Foo (const Foo& input)
	{
		this->a = input.a;
		cout << this << endl;
	}
	int a;
};

void foo()
{
	try {
		Foo *f = new Foo (100);
		throw *f;
	} catch (const Foo& e)
	{
		cout << e.a << endl;
	}
}

int main()
{
	foo();

Looks like we only get a temporary exception object in catch block?

CString str=_T("foo");
const TCHAR * psz = str; // implicit call to CString (LPCTSTR) cast operator

On the other hand, if you need a standard pointer, then you can't avoid using CString::GetBuffer method (and you have to be careful).

TCHAR * psz;

LPCTSTR pcsz;

MyCombo->SetCurSel(0);
