Visual Assist build 2029 and newer
By default, Visual Assist includes locally defined classes and typedefs in the Find Symbol in Solution dialog and Symbol in Solution drop-down. You can exclude the symbols from the dialog and drop-down by setting the following registry value to 00.
HKCU\Software\Whole Tomato\Visual Assist X\<IDE spec>\ParseLocalTypesForGotoNav
Set the value to 01 to restore default behavior.
Note: If you exclude locally defined classes and typedefs, Goto Related (Shift+Alt+G) may not work for derived symbols that are local to functions.
