I am trying to convert a legacy GUID on mircosoft to use the boost uuid. I am utilizing the stringstream as mentioned in the boost uuid documentation. I have managed to get the GUID converted into a string but am unable to inject the string value Into the uuid variable. Below is just a snippet of a test program. I read it back into a buffer variable to make sure that value was properly set. ss gets the value of guid_str but does not set the value in uuid_test. WCHAR guid_buf[50]; Boost::uuids::uuid uuid_test; StringFromGUID2(guid_value, guid_buf, 50); char *guid_str = OLE2A(guid_buf); std::stringstream ss; char buf[50]; ss << guid_str; ss >> uuid_test; ss << uuid_test; ss >> buf; Obvioulsy I am using stringstream wrong. Does anyone know how to convert a GUID to a boost UUID? I can't seem to find the documentation or interface.
