请问读写注册表分别用什么API函数, 谢谢!!!!!!!!!!!!!

Question

如题

Answer 1

The RegOpenKeyEx function opens the specified registry key.
LONG RegOpenKeyEx(
  HKEY hKey,
  LPCTSTR lpSubKey,
  DWORD ulOptions,
  REGSAM samDesired,
  PHKEY phkResult
);
The RegSetValueEx function sets the data and type of a specified value under a registry key.
LONG RegSetValueEx(
  HKEY hKey,
  LPCTSTR lpValueName,
  DWORD Reserved,
  DWORD dwType,
  const BYTE* lpData,
  DWORD cbData
);The RegQueryValueEx function retrieves the type and data for a specified value name associated with an open registry key.
LONG RegQueryValueEx(
  HKEY hKey,
  LPCTSTR lpValueName,
  LPDWORD lpReserved,
  LPDWORD lpType,
  LPBYTE lpData,
  LPDWORD lpcbData
);

Answer 2

写注册表～
RegCreateKeyEx()

Answer 5

给你个我以前用的函数:void WriteProfile(LPTSTR section, LPCTSTR key, DWORD dwType, CONST BYTE *lpData, DWORD cbData)
{
HKEY key1,key2,key3,key4;
DWORD d;
if (ERROR_SUCCESS==RegOpenKeyEx(HKEY_CURRENT_USER,"Software",0,KEY_READ,&key1))
{
if (ERROR_SUCCESS==RegCreateKeyEx(key1,"管理系统",0,0,REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,0,&key2,&d))
{
if (ERROR_SUCCESS==RegCreateKeyEx(key2,"客户管理",0,0,REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,0,&key3,&d))
{
if (ERROR_SUCCESS==RegCreateKeyEx(key3, section,0,0,REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,0,&key4,&d))
{
RegSetValueEx(key4, key, 0, dwType, lpData, cbData);
RegCloseKey(key4);
}
RegCloseKey(key3);
}
RegCloseKey(key2);
}
RegCloseKey(key1);
}
}
void GetProfile(LPTSTR section, LPTSTR key, LPBYTE lpData, DWORD cbData)
{
HKEY key1,key2,key3,key4; if (ERROR_SUCCESS==RegOpenKeyEx(HKEY_CURRENT_USER,"Software",0,KEY_READ,&key1))
{
if (ERROR_SUCCESS==RegOpenKeyEx(key1,"管理系统",0,KEY_READ,&key2))
{
if (ERROR_SUCCESS==RegOpenKeyEx(key2,"客户管理",0,KEY_READ,&key3))
{

if (ERROR_SUCCESS==RegOpenKeyEx(key3,section,0,KEY_READ,&key4))
{
RegQueryValueEx(key4, key, 0, 0, lpData, &cbData);
RegCloseKey(key4);
}
RegCloseKey(key3);
}
RegCloseKey(key2);
}
RegCloseKey(key1); }}
调用:
 WriteProfile("settings","Flag",REG_SZ,(LPBYTE)"2",2) ;GetProfile("Settings","flag", (unsigned char *)&flag,2);
