Why you want costly refreshing in this case? Any way it will not take much time to complete the loop. You can consider using
WM_SETREDRAWfor refreshing list box. You should ask such question in VC++[^] forum. As there is nothing specific toCLIin this question.Prasad Notifier using ATL | Operator new[],delete[][^]

Thanks Prasad! for ur reply, but there is no effect after modifying my code for(int i=1;i<=100;i+=1) //Loop { if(i%10==0) { SendDlgItemMessage(IDC_LIST3, LB_INSERTSTRING, (WPARAM) -1, (LPARAM) _T("HP Laser Jet 5000 Series PCL 6")); //Adding String in ListBox SendDlgItemMessage(IDC_LIST3, WM_SETREDRAW , 1, 1);//Code is added here } } Acually i want to add in listbox with the progresbar so I need to refresh listbox to show simulteneous progress, If u hv any other idea please share with me. I will take care about ur suggession in future. Thanks
