Thanks, that is what I was suspecting.
Is there already something in boost to do what I intend to do? If not, which strategy would you recommend to by pass this issue? I got some ideas but nothing straight forward and I would like it to be as efficient as possible.
Thanks again,
Nicolas
In this particular case, you can do the following: Iterator it2 = m_Container.get< CollectionID >().lower_bound( 30 ); while( it2!=m_Container.get< CollectionID >().end() && it2->CollectionID==30) { int time = it2->TCoord; if( time < 500 ) // we want to change the collection ID in this case { Structure tempStructure(*it2); tempStructure.CollectionID = 40; m_Container.get< CollectionID >().replace(it2++, tempStructure); } else ++it2; } I haven't compiled it, but I think it should work. Two notes about the code: 1. Note that in the invocation to replace() we do a post-increment of it2, so that it2 points to the following element before the current one is replaced and, consequently, moved to a new position. 2. The while condition of the loop has changed: as a result of replacements, it could be the case that modified elements get between the range of elements with CollectionID==30 and it3, so checking for it2!=it3 is not safe.
