HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
\HotFix
是不是只对XP有效？
找到一个类专门实现这个功能：
class CXP_Hotfix
{
public:
CAtlArray<CString> m_aHotFix;
public:
CXP_Hotfix()
{
ShowList();
}
void ShowList()
{
CRegKey key; // an object of CRegKey's class
if (key.Open(HKEY_LOCAL_MACHINE, _T("Software\\Microsoft\\Windows NT\
\CurrentVersion\\HotFix"), KEY_READ) != ERROR_SUCCESS)
return; // stop if we can't open the key.
// Initialize
DWORD cpt = 0;
DWORD size = 256;
TCHAR SubKeyName[256];
LONG a;
// Initialize
// Enumeration while we find an item....
while ((a = key.EnumKey(cpt, SubKeyName, &size)) !=
ERROR_NO_MORE_ITEMS)
{
if (a==ERROR_SUCCESS) // an item was found...
{
CRegKey SubKey; // an object of CRegKey's class.
if (SubKey.Open(key, SubKeyName,
KEY_READ)==ERROR_SUCCESS)
{
// "The doors are open"....get the "Fix
Description".
ULONG ulong;
if (SubKey.QueryStringValue(_T("Fix
Description"), NULL,
&ulong)==ERROR_SUCCESS)
{
// We can retrieve a value now.
CString name;
SubKey.QueryStringValue(_T("Fix
Description"),
name.GetBuffer(ulong), &ulong);
name.ReleaseBuffer(); // Clean
the string.
m_aHotFix.Add(name); // add the
string to the array.
}
}
}
cpt++;
size=256;
}
key.Close(); // close the registry key.
}
};
