in wpf project, i'm validating textbox input inotifydataerrorinfo implementation. multiple errors can occur. when input causes multiple errors, validation errors displayed. however, when fix 1 error, validation message doesn't change, means false error messages shown. when fix errors message disappears. is problem implementation, or wpf implementation re-fetch validation message if haserrors changed? stepping through debugger, however, can see geterrors , haserrors both called. steps reproduce attached example: enter 333333. 2 validation messages shown. change leading 3 2. still, both validation messages shown, although first error has been fixed. change second 3 0. both messages disappear change second digit 3 again. second validation message shown. change leading digit 3 again. second validation message shown, although should display both. and yes, example doesn't make sense, since rid of first check, since it's included in second check. the view...

the current implementation general swap in standard library like template <class t> void swap(t& a, t& b) { t c(move(a)); = move(b); b = move(c); } i'm wondering whether can following instead. template <class t> void swap(t& a, t& b) { unsigned char x; auto pa = reintepret_cast<unsigned char*>(&a); auto pb = reintepret_cast<unsigned char*>(&b); auto pc = pa + sizeof(a); while (pa != pc) { x = *pa; *pa = *pb; *pb = x; ++pa, ++pb; } } i think implementation better in terms of space usage, takes 1 byte. there many considerations need addressed when swapping classes. pod types, swapping bytes works correctly. more complicated classes, however, may rely on invariants byte-swapping won't respect. example, consider reference member variable: struct foo { foo() : bar{}, barref{bar} {}; int bar; int& barref; // expected refer neighboring `bar` }; int main() { ...
