//
// Summary:
// Called to fill and synchronize all combo boxes.
//
// Parameters:
// languageService:
// [in] A Microsoft.VisualStudio.Package.LanguageService object representing
// the language service that uses the combo boxes.
//
// textView:
// [in] An Microsoft.VisualStudio.TextManager.Interop.IVsTextView object representing
// the view the combo boxes are placed in and the view that shows the source
// file.
//
// line:
// [in] The line number the caret is currently on.
//
// col:
// [in] The character offset the caret is currently on.
//
// dropDownTypes:
// [in, out] An System.Collections.ArrayList of Microsoft.VisualStudio.Package.DropDownMembers
// representing the types combo box.
//
// dropDownMembers:
// [in, out] An System.Collections.ArrayList of Microsoft.VisualStudio.Package.DropDownMembers
// representing the members combo box.
//
// selectedType:
// [in, out] The index of the entry to be selected in the types combo box. This
// can also be set if the current selection is invalid.
//
// selectedMember:
// [in, out] The index of the entry to be selected in the members combo box.
// This can also be set if the current selection is invalid.
//
// Returns:
// If successful, returns true if the combo boxes have been changed; otherwise
// returns false.
