三问文件夹选项更改后刷新的问题

[日总是我哥]

上一次经过palmax的指点，使用SHGetSetSettings函数可以实现刷新，但是，该函数在Win2k下无效，据msdn中对SHGetSetSettings的介绍：“This function is available through Microsoft Windows XP Service Pack 2 (SP2) and Windows Server 2003. It might be altered or unavailable in subsequent versions of Windows.”，

Win2k的注册表也有相应的选项：
[code=INIFile]
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"Hidden"=dword:00000002
"ShowCompColor"=dword:00000000
"HideFileExt"=dword:00000001
"DontPrettyPath"=dword:00000000
"ShowInfoTip"=dword:00000001
"HideIcons"=dword:00000000
"MapNetDrvBtn"=dword:00000000
"WebView"=dword:00000001
"Filter"=dword:00000000
"SuperHidden"=dword:00000000
"SeparateProcess"=dword:00000000
"StartButtonBalloonTip"=dword:00000001
"StartMenuInit"=dword:00000001
[/code]

求在Win2k下的实现方法。

谢谢，测试通过！

通过使用spy++等工具监测，现给出终极方法：(修改注册表 + WM_SETTINGCHANGE 通知更新)

bool ShowAllFilesInExplorer(bool bShowHidden/*对应[显示所有的文件和文件夹]*/, bool bShowSysProtected/*对应[显示受操作系统保护的文件]*/)
{
	HKEY hKey = {0};
	bool bRet = true;

	if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CURRENT_USER, TEXT("Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"), 0, KEY_SET_VALUE, &hKey))
	{
		DWORD dwShowHidden = bShowHidden ? 1 : 2;
		DWORD dwShowSysProtected = bShowSysProtected ? 1 : 0;

		if (ERROR_SUCCESS != ::RegSetValueEx(hKey, TEXT("Hidden"), 0, REG_DWORD, (LPBYTE)&dwShowHidden, (DWORD)sizeof(dwShowHidden)) 
			|| 
			ERROR_SUCCESS != ::RegSetValueEx(hKey, TEXT("ShowSuperHidden"), 0, REG_DWORD, (LPBYTE)&dwShowSysProtected, (DWORD)sizeof(dwShowSysProtected)))
		{
			bRet = false;
		}

		::RegCloseKey(hKey);
	}
	else
	{
		bRet = false;
	}

	if (bRet)
	{
		::SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM)TEXT("ShellState"), SMTO_ABORTIFHUNG, 3000, NULL);
		::SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, NULL, NULL);
	}

	return bRet;
}
