This could be just 'int', as you use to_int().

static HRESULT return_int(VARIANT *res, int val)
{
- if((short)val == val)
- return return_short(res, val);
-

That's a questionable thing to do as it affects all other places where this helper is used.

You are right, but I will check that whether all the functions who call to_int() use these codes, I think these are unnecessary, cause we should use to_int and to_short seperately in order to get return values of different types, i.e. VT_I2 and VT_I4, especially for the smaller numbers such as 0.

+ if(color[i] > 255)
+ color[i] = 255;

This needs a test too.

Yeah, good idea.

+ total = color[0] + 256 * color[1] + 256 * 256 * color[2];

RGB() macro does the same thing.

I don't quite understand this line..will you explain it in detail please?
