WINCE与WM的差异(1)－查询文件系统目录结构

 

MSDN :http://msdn.microsoft.com/zh-cn/office/ee490204  Storage Manager Functions (Windows Embedded Compact 7)

(msdn，我用的太悲剧了，每次都不能快速的在目录索引下找到WinCE的目录，但偶尔翻的翻的就不知道怎么翻到WinCE的目录了，7也是。。。)

还没结束，今天没时间测试了，也没机器，

工作的机器放资源的分区是隐藏的，每次放资源或程序的时候感觉忒麻烦。。尤其是心情烦躁的时候。

目标：做一个程序，一点击就修改注册表键值 ，将对应分区注册表隐藏设置为显示，然后卸载分区，再加载分区，应该会方便。

明天继续

---------------------------------------------------------------------------------------------------------------------------------

//将要显示的分区的注册表隐藏设置为假。

void CPartitionControlDlg::ChangeRegKeyValue()
{
	HKEY	hOpenKey;
	DWORD   dwKeyValueType = 0;
	DWORD	dwKeyValue;
	DWORD   dwKeyValueLength = sizeof(DWORD);
	if(ERROR_SUCCESS == RegOpenKeyEx( HKEY_LOCAL_MACHINE, L"System\\StorageManager\\Profiles\\Nand\\NANDFATFS",0, 0, &hOpenKey ))
	{
		long lResult = 0;
		lResult = RegQueryValueExW( hOpenKey, L"MountHidden", 0, &dwKeyValueType,(BYTE*)&dwKeyValue, &dwKeyValueLength);
		if(lResult ==ERROR_SUCCESS)
		{
			printf("读取注册表成功,achKey = %d\n",dwKeyValue);
			dwKeyValue = 0;
			RegSetValueExW(hOpenKey,L"MountHidden",0,dwKeyValueType,(BYTE*)&dwKeyValue,dwKeyValueLength);
			
		}
		else
		{
			printf("读取失败 :lResult = %d\n",lResult);
		}
		
			//RegSetValueEx(hKey, TEXT("Screen"), 0, dwType, (LPBYTE)&dwData, dwDataLen);
		RegCloseKey( hOpenKey );
	}

}

//卸载、加载指定分区

void CPartitionControlDlg::OnBnClickedButton2()
{
	// TODO: Add your control notification handler code here

	ChangeRegKeyValue();

	HANDLE h_openStore;
	h_openStore = OpenStore(L"DSK1:");
	HANDLE h_NandPart;
	PARTINFO PartInfo;
	PartInfo.cbSize = sizeof(PARTINFO);
	h_NandPart = OpenPartition(h_openStore,L"Part01");

	if (DismountPartition(h_NandPart))
	{
		printf("NAND分区卸载成功\n");
	}
	else
	{
		printf("NAND分区卸载失败\n");
		MessageBox(L"显示NAND失败");
		CloseHandle(h_NandPart);
		CloseHandle(h_openStore);
		return;
	}
	if (MountPartition(h_NandPart))
	{
		printf("NAND分区加载成功\n");
	}
	else
	{
		printf("NAND分区加载失败\n");
		MessageBox(L"显示NAND失败");
		CloseHandle(h_NandPart);
		CloseHandle(h_openStore);
		return;
	}

	CloseHandle(h_NandPart);
	CloseHandle(h_openStore);
