delphi - The listviewer not change select in onshow -


how can change selected item in listview...

here code sample:

 c := 0  form1.lv1.items.count -1      begin       if  (form1.lv1.items[c].subitems.objects[3] ttabsheet).tabindex =          pgc1.activepageindex       begin         form1.lv1.items[c].selected:= true;       end;     end;

i created simple application list view, set report mode, added items, , added onshow event:

procedure tform1.formshow(sender: tobject); begin   listview1.items[1].selected := true; end;

the specified item indeed selected.

the conclusion draw selected property can used onshow event. therefore, if program not result in list view selection set, seem either:

  1. the code in question not running @ all, or
  2. the code running, if statement condition never true.

your next step debug program. inspect program executes using preferred debugging technique. interactive debugger sound choice.

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.
