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.
