I am not selecting anything.
I want to dynamically fill up the combo box list, when it is displayed
and remove everything leaving just
one line in after it is pops up.
To give you an exampple:
I have a dialog with the combo box. The text in the combo box says:
"Make a selection".
When I click on the combo box arrow to display the list, the strings I
see are "Choice 1", "Choice 2", "Choice 3".
No "Make a selection".
Then after selection is made all strings are disappear and I am seeing
"Selected - Choice 1".
And so internally there is only one string available which is
This is what I mean by dynamically filled combo box.
