wpf - Does message exchange between View and ViewModel break MVVM pattern -


i have complex view usercontrols need updated. easiest way of doing so, see far, using message mediation service mvvm light messenger. in case need have handling code in view, isn't ideal in mvvm.

does message exchange between view , viewmodel break mvvm pattern?

edit: clear things little, example, if need programatically add new usercontrol view signalled viewmodel. how can achieved?

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
