I have a CXTPControlComboBox control used in a RibbonBar. The only notification that I can get if the user edits the edit control of the combobox is a CBN_EDITCHANGE message. ON_XTP_EXECUTE does not fire on the edit change (only the listbox change). The problem is that when the user uses the listbox part of the control, there are actually two CBN_EDITCHANGE messages fired. I traced this to the function _SetEditText. When this function is called to insert text into the edit control, if first inserts a NULL entry (causing the message to fire) and then inserts the "real" text causing the second message.

My work around is to test if the GetEditText returns an empty string (the NULL insert) and then ignore that message. However this forces me to not allow the user to have an empty string as a valid input.

Thanks, we will add flag to ignore first CBN_EDITCHANGE.
