ComboBox Edit Text neither visible nor hidden

Hi,

There are a combo box which displays the file name and file type of a file. When I try to display the text of the combobox, it only returns the file name. I just figured out, using Window Info Tool , than the only visible text is the file name and the file type is neither visible nor hidden. Please help.

Thanks

WinWaitActive("Properties")
Sleep(500)
$select = ControlGetText("Properties", "", "[CLASS:ComboBox; INSTANCE:1]")
MsgBox(0, "", $select)
