Q.  It's such a chore setting each struct member to zero.
    Is there a faster/less tedious way?

A.  Use ZeroMemory() like this:

struct MyStruct
{
	int	a;
	float	b;
	char	c;

	MyStruct() // default constructor
	{
		ZeroMemory((LPBYTE)this, sizeof(*this));
	}
};

This works for *some* classes too but be very careful.
If you have virtual functions, it will klobber your vtable!
So only use on the most simple classes.
