Template based Registry class with serialization


Desktop-as-a-Service Designed for Any Cloud ? Nutanix Frame

It was inspired by the registry API wrapper class by Shane Martin which you can find here at codeguru.

Environment: VC6 SP3, NT4 SP5

I first used the registry class provided by Shane. But - for my purposes - I needed other functionality. So I wrote my own code.
This class now provides the capability of reading and writing any kind of object which supports archive operation (template based).
Some of these are:
  • BYTE
  • WORD
  • int
  • LONG
  • float
  • double
  • SIZE and CSize
  • CString
  • POINT and CPoint
  • RECT and CRect
  • CTime and CTimeSpan
It further provides the capability to serialize object structures to the registry using the objects "Serialize(CArchive& ar)" function.
(Be sure that these structures are smaller than 2048 bytes - otherwise an *.ini file or something would be better.)

Another feature is that you can save and resore the settings of the application window(s) by simply passing a pointer to the "Read" or "Write" Function.

Usage is very simple...

	CRegistry reg;
	CString sRegPath("YourApp\\Path\\Settings");	

	CString 	sString("I am a String");
	CString 	sStringBin("I am a binary String");
	int		nValue = -1234567890;
	double		dValue = -1234567890.1234;
	DWORD		dwValue = 1234567890;
	DWORD		dwValueBin = 1234567890;
	CRect		rcWnd;
	CYourObject 	object;

	// Fill the rcWnd...

	// Check the key...
	if (!reg.VerifyKey(HKEY_CURRENT_USER, sRegPath))
		reg.CreateKey(HKEY_CURRENT_USER, sRegPath);

	// Open...
	reg.Open(HKEY_CURRENT_USER, strRegPath);

	// Writing/Reading as "String"...
	reg.WriteString("CString", sString);
	reg.ReadString("CString", sString);

	// Writing/Reading String as "binary" (template function)...
	reg.WriteType("CStringBin", sStringBin);
	reg.ReadType("CStringBin", sStringBin);

	// Writing/Reading int as "binary" (template function)...
	reg.WriteType("int", nValue);
	reg.ReadType("int", nValue);

	// Writing/Reading double as "binary" (template function)...
	reg.WriteType("double", dValue);
	reg.ReadType("double", dValue);

	// Writing/Reading DWORD...
	reg.WriteDWORD("DWORD", dwValue);
	reg.ReadDWORD("DWORD", dwValue);

	// Writing/Reading DWORD as "binary" (template function)...
	reg.WriteType("DWORDBin", dwValueBin);
	reg.ReadType("DWORDBin", dwValueBin);

	// Writing/Reading CRect as "binary" (template function)...
	reg.WriteType("CRect", rcWnd);
	reg.ReadType("CRect", rcWnd);

	// Writing/Reading Window (WINDOWPLACEMENT)...
	reg.Write("Wnd", this);
	reg.Read("Wnd", this);

	// Writing/Reading CObject...
	reg.Write("Object", object);
	reg.Read("Object", object);
	// Not necessary (object is automatically closed at destruction)

For further explanation look at the sample application.
If you have any questions or some ideas how to improve this, bugs, errors, etc. feel free to send me a mail.

    Hi folks,
    I have an updated version which features read/write raw data and implements optional encryption using the CryptoAPI. Further on access rights are added ;-).
    Send me an email if you're interested in it.

  • Thank you!!!

  • Access rights should be added

    all the functions, instead of assumming KEY_ALL_ACCESS.
    This will cause an error if the owner of the process does
    not have admin rights on NT and wants to read initial values
