c# - Is STAThread attribute a requirement or recommendation? -


i wrote managed extension autocad. when autocad loads extension launch iextensionapplication.initialize() method. need method launched in main thread of application. enough set stathread attribute method purpose? attribute requirement or recommendation?

the [stathread] attribute works on main() entrypoint of standalone executable program. promise make operating system, telling main thread of program "well-behaved". must pump message loop , never block. breaking promise causes hard diagnose misbehavior, deadlock common.

none of applies when write autocad extension. did not create thread, autocad did. can't make promises, autocad has implement them. nor "main thread", that's term can apply standalone program.

the thread calls extension single-threaded apartment, can use thread.getapartmentstate() in code double-check. sta requirement thread displays ui, commonly in extension.

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.
