But when I try to use Upp::String then the created com object (dll) does not load into other system.

BTW, I think you can try
Quote:

WString -
WString implementation does not use small string optimization, first step is 23 wchars stored in 48 bytes memory block without reference counting, for larger string once again reference counting is applied. Sizes are also directly stored in "int" member variables.

it is exactly like BSTR - according to this description taken from U++ Help topics
