c++ - How to find and replace an items in a ComboBox -

in c++ builder xe8, i'm using following methods insert item combobox:

mycombobox->items->beginupdate(); mycombobox->items->insert(0, "title"); mycombobox->items->insert(1, "google"); mycombobox->items->insert(2, "yahoo"); mycombobox->items->insert(3, "127.0.0.1"); mycombobox->itemindex = 0; mycombobox->items->endupdate(); 

i want know how replace 3rd item, 127.0.0.1, "xxx.0.0.1". i've tried using stringreplace(), no luck.

first, example should using add() instead of insert() (and try/__finally block or raii wrapper, in case exception thrown):

mycombobox->items->beginupdate(); try {     mycombobox->items->add("title");     mycombobox->items->add("google");     mycombobox->items->add("yahoo");     mycombobox->items->add("127.0.0.1");     mycombobox->itemindex = 0; } __finally {     mycombobox->items->endupdate(); } 

now, said, if know item want change fourth item, update directly:

mycombobox->items->strings[3] = "xxx.0.0.1"; 

if need search it, use indexof():

int index = mycombobox->items->indexof("127.0.0.1"); if (index != -1)     mycombobox->items->strings[index] = "xxx.0.0.1";
