c# - Invoking control from a different thread fails with a cross-threading exception -


in windows forms project have subscribed global keyboard event using win32 api fire event when press win + alt + e, in event handler have code:

    _rectangle = new screenboundingrectangle();     _rectangle.location = location;     _rectangle.visible = true;

i keep variable rectangle, based on logic, want hide rectangle set visibility false using line of code:

    _rectangle.visible = false;

however famous cross threading exception, if try :

this.invoke(new methodinvoker(() =>     {         _rectangle.visible = false;     }));

i still cross threading exception!

the _rectangle not have invoke method, there other way around ?

just use visualuiaverify library , face issue:

download open source , add visiable property of screenboundingrectangle

        public bool visible         {             { return this._visible; }             set             {                 this._visible = value;                  if (value)                     safenativemethods.showwindow(_form.handle, 8);                 else                 {                     //here invoke _form:                     this._form.invoke(new methodinvoker(() =>                     {                         _form.hide();                     }));                  }             }         }

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.
