c# - (Interop.Word) Range.Copy-Range.Paste work slow -

i use microsoft.office.interop.word create new doc based on doc. there multiple iterations search/replace operations using range.text , work pretty fast. however, in 1 case need copy entire chapter formatting , instead of range.text (which resets formatting) used range.copy , range.paste. work, test chapter 450 words, take 40 sec (vs. less 1 sec when change same code use range.text). question: there way make range.copy/range.paste faster? need find particular piece of text , copy tables, formatting, etc. file. if want copy text formatting in word can use formattedtext property of range like targetrange.formattedtext = sourcerange.formattedtext; avoid using range.copy() , range.paste() approach internally use clipboard may cause security problems or may provide unpredictable results in cases

c - How can I make code that concurrently reads and modifies an array well-defined without introducing locking? -

i'm writing program computes endgame tablebase chess variant. algorithm filling tablebase works this: start huge array of unsigned char , each member representing 1 position (we assume it's white's turn). array member if position lost, odd if won, 0xff if invalid, 0xfe if draw. iterate on array, marking each illegal position 0xff , each position white mated 0x00 , other positions 0x0fe . iterate on array, considering positions marked 0xfe . check if there move leads position array member even, if there one, write 1 plus number of position member corresponding curren position. if moves lead positions indicated odd numbers (i.e. loosing position), mark position 1 plus highest of these numbers indicate how long strongest defence takes. repeat step 3 until array doesn't change anymore. for speed, i'd parallelize step three. careful reading yields in each iteration, ever write 1 value (the number of iteration) array. following strategy obtains: split ...
