Klasser og PlatformsSDK

Jeg er igang med et forsøg på at lave en meget lille editor. Jeg er kommet til et sted hvor jeg gerne vil kunne gemme i "Regedit". Derfor har jeg lavet følgende klasse:

Regedit.h

#ifndef REGEDIT_H
#define REGEDIT_H

#include <windows.h>

class Regedit
{
public:
	Regedit(string comp, string application);
	~Regedit();

	bool write(string varName, string value, string adPath = "");
	string read(string varName, string adPath = "");

private:
	string company;
	string app;
	HKEY hKey;
};

#endif

Regedit.cpp:

#include <string.h>

#include "regedit.h"

Regedit::Regedit(string comp, string application)
{
	company = comp;
	app = application;
}

Regedit::~Regedit()
{
	RegCloseKey(hKey);
}

bool Regedit::write(string varName, string value, string adPath)
{
	if (adPath.lenght() > 0)
		string path = "Software\\\\" + company + "\\\\" + app + "\\\\" + adPath;
	else
		string path = "Software\\\\" + company + "\\\\" + app;

	if (RegCreateKeyEx(HKEY_CURRENT_USER, path, 0,0, REG_OPTION_NO_VOLATILE,
		KEY_ALL_ACCESS, 0, &hKey, 0) == ERROR_SUCCESS)
	{
		RegSetValueEx(&hKey, varName, 0, REG_SZ, &value, sizeof(value));
		return true;
	}

	return false;
}

string RegEdit::read(string varName, string adPath)
{
	if (adPath.lenght() > 0)
		string path = "Software\\\\" + company + "\\\\" + app + "\\\\" + adPath;
	else
		string path = "Software\\\\" + company + "\\\\" + app;

	if (RegOpenKeyEx(HKEY_CURRENT_USER, path, 0, KEY_ALL_ACCESS, &hKey) == ERROR_SUCCESS)
	{
		string value;
		RegQueryValueEx(hKey, varName, 0, REG_SZ, value, sizeof(string));
		return value;
	}
	else
		return "";
}

Men når jeg compiler dette får jeg følgende fejl:
