i'm trying add child node treeview in winforms app (using c#). problem when use following code winform looks wrong visually. here's example: if (treeview1.nodes.count == 0) { treenode newguy = new treenode("new_subitem"); treeview1.nodes[0].nodes.add(newguy); newguy.beginedit(); return; } treenode n = treeview1.selectednode; treenode n3 = new treenode("new_subitem"); n.nodes.add(n3); n3.beginedit(); return; here happens: doing wrong? if (treeview1.nodes.count == 0) { treenode newguy = new treenode("new_subitem"); treeview1.nodes[0].nodes.add(newguy); newguy.beginedit(); return; } that code senseless: first check treeview1 has no nodes(treeview1.nodes.count == 0), try access first node it's correct(treeview1.nodes[0])

Are C++ constructors called pre-initialization? -

suppose declare a of type type : type a; question: type constructor a called @ point? or after initialize a constructor called? is type constructor called @ point? or after initialize constructor called? you are initializing a here, whether explicitly provided value process or not. there no opportunity initialise a "later"; can assign later. (early c texts talk "initialising" numeric values long after declaration, that's different language, different century, , different set of descriptive idioms.) so, yes, constructor called object's lifetime begins. that's either right there , then, on line, or if class member of course it's when encapsulating class being initialised , it's member's turn. of course have proven simple std::cout pair.

c - How to pass an array of integers to a function as an argument and modify the content? -

i trying modify array of integers through function, array maintains original values. tried accesses values modify it: this produces error: *array[i] = *array[i] * *array[i]; this example runs program array modified: int main() { int array[] = {1, 2, 3, 4, 4, 5, 6}; int size = sizeof(array)/sizeof(int); square_array_values(&array, size); } void square_array_values(int *array, int size) { int i; (i = 0; < size; i++) { printf("array[%d]: %d.\n", i, array[i]); array[i] = array[i] * array[i]; } } this late answer party - hope gives ideas how add prints code show going on. consider output following program. there several ways approach this, 1 possibility. of earlier answers solid , should give ideas. you're going need build mental model of how memory allocation works in c can predict compiler do. find printing out values of variables , addresses helpful. benefit sketching "memory map" paper ...

bash - Capture output of last executed command into a variable without affecting Vim and line returns -

from question: bash - automatically capture output of last executed command variable used command: prompt_command='last="`cat /tmp/x`"; exec >/dev/tty; exec > >(tee /tmp/x)' it works, when use vim this: # vim vim: warning: output not terminal then vim opens. takes while. there way rid of message , slowdown? also when list dir , echo $last removes return lines (\n). there way keep return lines (\n)? i think ask hard achieve. vim tests if output terminal. command you've provided redirects output tee command. tee saves input (which menans: command's output) file and outputs terminal. vim knows nothing it. knows output not terminal. outputs warning. , vim 's source code: [...] if (scriptin[0] == null) ui_delay(2000l, true); time_msg("warning delay"); which means redirection 2 seconds delay. also, example, man vim command not work such redirections, because terminal output has attributest (e.g. width , h...
