返回值

This function returns an integer value that indicates the type of variant, which can be an instance of com, dotnet or variant classes. The return value can be compared to one of the VT_XXX constants.

The return value for COM and DOTNET objects will usually be VT_DISPATCH; the only reason this function works for those classes is because COM and DOTNET are descendants of VARIANT.
