I've searched on Google but not too sure on what the name of the message/CB_Style is, and its hard to search for something when you don't know what it's called.
Thanks in advance.
EDIT:
I'm NOT looking for how to add an item to the combo box, I already know how to do that. I want to change the text that is shown on top, when no selection of the combo box items has been made.
I think Ramses12's solution is probably the best: SendMessage(m_hWnd, CB_SETCURSEL, nIndex, 0); (wherenIndexis the location of the default string to display) .
As for the reason why "Country" is not being displayed (I think), is that the default string might not appear, depending on styles you have set (see section: "Windows Styles of a Combo Box" @ http://www.functionx.com/win32/controls/combobox.htm ).
