By default, the Repair Case feature does not convert a symbol typed in mixed case to all lower case. Visual Assist assumes typed mixed case is deliberate. In the following example, Visual Assist will not repair nFooBar to nfoobar since nFooBar was typed in mixed case.
int nfoobar;
nFooBar = 2;
If you want Visual Assist to correct the typing of mixed-case symbols, set the following in the registry:
HKCU\Software\Whole Tomato\Visual Assist X\<IDE spec>\OverrideRepairCase1 = 00
Set to 01 to restore default behavior.
