In your windowProc do something like this: switch(message)
{
case WM_COMMAND:
{
switch(HIWORD(wParam))
{
case CBN_DROPDOWN:
//do something
break;
}
}
break;
}

switch(message){
case WM_COMMAND:
{
switch(HIWORD(wParam))
{
case CBN_DROPDOWN:
//Get the control ID of the ComboBox
int idComboBox = (int)LOWORD(wParam);
if(idComboBox == IDC_COMBO1)
//Do something
else if(idComboBox == IDC_COMBO2)
//Do something else
break;
}
}
break;
