You are using wrong message for setting value.
CB_SETITEMDATAis used to set item data for particular index. I'm not clear about your wording, I'm assuming that you want first value to be selected and default selection. You do this by using,HWND hwndCombo = GetDlgItem(hwnd, IDC_COMBO);
SendMessage(hwndCombo,CB_CB_SETCURSEL,0,0);Prasad Notifier using ATL | Operator new[],delete[][^]

No its not working I tried with both , and also ; . actually I am working on win32 api and not MFC.
If you use of
CB_ADDSTRINGfor insert data to combobox instead property window what happens?
