before flag question being duplicate, hear me out. most people have long running non-ui operation doing , need unblock ui thread. have long running ui operation must run on ui thread blocking rest of application. basically, dynamically constructing dependencyobject s @ run time , adding them ui component on wpf application. number of dependencyobject s need created depends upon user input, of there no limit. 1 of test inputs have has 6000 dependencyobject s need created , loading them takes couple minutes. the usual solution of using background worker in case not work, because once dependencyobject s created background worker, can no longer added ui component since created on background thread. my current attempt @ solution run loop in background thread, dispatch ui thread each unit of work , calling thread.yield() give ui thread chance update. works - ui thread chance update couple times during operation, application still blocked. how can application keep updating ...

is there way have vba select field in word doc using name attribute of field code property? maybe using pseudo selector? background: have 8 fields (docproperty name_first, name_last, etc) in document in 4 places (total 32 items) instead of looping through entire collection of fields, want able return collection of fields match name_first, , make changes,insertafter, etc, call update method on fields only. updating fields causing noticeable delay on each form field when exited next field. the msdn documentation shows examples using ordinal index numbers, isn't helpful in real world. if changes ordinal position of field, donkeykong! a bookmark can referenced name. if want update 4 fields reflect name_first, place bookmarks on 4 fields names "name_first_1", "name_first_2" etc. update fields like: for = 1 4 activedocument.bookmarks("name_first_" & i).range.fields(1).update next in words: bookmarked range pseudo selector. field...
