regentry.h

Abstract:
|
||
|
|
|
||
|
|
Wrapper for registry access Win32 APIs
|
||
|
|
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
|
||
|
|
Construct a RegEntry object by specifying the subkey (under
|
||
|
|
HKEY_CURRENT_USER by default, but can be overridden.)
|
||
|
|
|
||
|
|
All member functions are inline so there is minimal overhead.
|
||
|
|
|
||
|
|
All member functions (except the destructor) set an internal
|
||
|
|
error state which can be retrieved with GetError().
|
||
|
|
Zero indicates no error.
|
||
|
|
|
||
|
|
RegEntry works only with strings and DWORDS which are both set
|
||
|
|
using the overloaded function SetValue()
|
||
|
|
|
||
|
|
SetValue("valuename", "string");
|
||
|
|
SetValue("valuename", 42);
|
||
|
|
|
||
|
|
Values are retrieved with GetString() and GetNumber(). GetNumber()
|
||
|
|
allows you to specificy a default if the valuename doesn't exist.
|
||
|
|
|
||
|
|
DeleteValue() removes the valuename and value pair.
