How do I check a Variant whether the text(string) in it is a VT_BSTR or VT_BSTRT?
I find that the vt variable is always 0x0008 i.e. VT_BSTR,
but if you use V_BSTR() or V_BSTRT() to convert it to a CString you get very different results.
Can any one tell me how to determine which V_XXX should I use each time?
