you gave each combobox a unique id when you created it. Just use it.

what version of vc++ are you using?

There are a lot of combo box messages See this MSDN article

Can't you just double click each combobox and edit the code for when each combobox is changed? It might provide you with a different event by default, not sure, but I think there is one for combobox changed.

Tyler: that would be horribly inefficient. Windows message contains the ID to the combo box that was changed.

I dont know but if you are using WIN32
With WM_COMMAND notification, you can have a look of lParam.

lParam Handle to the control sending the message if the message is from a control. Otherwise, this parameter is NULL.

thank you for your help, found what I was looking for and this is it :

if (LOWORD (wParam) == DAY_COMBOBOX && HIWORD (wParam) == LBN_SELCHANGE)

Thank You :cheesy:
