i'm trying develop application can read files. don't know how can change position of reader pointer, please? for(int i=0; i<tab.length; i++){ char cbuf[] = new char[tab[i]]; try { inputstream ips=new fileinputstream(fichier); inputstreamreader ipsr=new inputstreamreader(ips); bufferedreader br=new bufferedreader(ipsr); //i need change position of pointer here br.read(cbuf, 0, tab[i]); tabs[i] = new string(cbuf); system.out.println(tabs[i]); br.close(); } catch (exception e){ system.out.println(e.tostring()); } } the read command lets take in next character. use loop take in characters // reads , prints bufferedreader int alength = 10; int array[] = new int [alength]; int value = 0; int index = 0; while((value = br.read()) != -1 && index < alength) { array[index++] = value; }

i have little question: made little program every time user click on qpushbuton new object created pointer, here code: ajoute *az = new ajoute; qvboxlayout *layoutprincipal = new qvboxlayout; the problem every object have been created have same name if want delete object there have error ? p.s : sorry bad english, i'm french the problem every object have been created have same name if want delete object there have error? it seems creating group of dynamically allocated objects , don't know how store pointers. simplest way use qvector<ajoute*> , store dynamically allocated objects: qvector<ajoute*> v; now whenever create ajoute do: v.push_back( new ajoute ); that add pointer @ end of vector (container). can access them in order doing: v[0]; // first v[1]; // second v[2]; // third and can delete them as: delete v[0]; // example just remember delete pointer inside vector well: v.remove(0);
