bool AIT_RegGetDWORDValue(
  integer nHKeyHandle,      // Key handle
  string strRegKeyName,     // Registry sub-key name
  string strRegValueName,   // Registry value name
  integer nRegValueData     // Registry value data
);

nHKeyHandle (input)

Specify a handle to an already opened registry key, or one of the following values.

• HKEY_CLASSES_ROOT
