0.将 EasyX 绘图窗口设为桌面实时动态视屏壁纸截图（桌面壁纸：字符雨与星空）

1.技术流程

EasyX 绘图窗口内容设为实时桌面动态视屏壁纸。有三个关键技术流程：

设置分裂桌面窗口函数：向桌面窗口发送 0x52C 消息，使其分裂为，三层三个窗口。分别为 1 层图标窗口（WorkerW1）、2 层静态壁纸窗口（WorkerW2）、3 层最底层窗口（Progman）。
```
SendMessageTimeout(hProgman, 0x52C, 0, 0, 0, 100, 0);	// 给它发特殊消息
```

设置隐藏第二层静态，壁纸窗口函数（WorkerW2）：隐藏越来第二层窗口，露出设置的 Progman 窗口，里头的子窗口上的 EasyXWnd 窗口类（我们自绘制的程序窗口）。

BOOL CALLBACK EnumWindowsProc(_In_ HWND hwnd, _In_ LPARAM Lparam)
{
	HWND hDefView = FindWindowEx(hwnd, 0, L"SHELLDLL_DefView", 0);
	if (hDefView != 0)
	{
	// 找它的下一个窗口，类名为 WorkerW，隐藏它
		HWND hWorkerw = FindWindowEx(0, hwnd, L"WorkerW", 0);
		ShowWindow(hWorkerw, SW_HIDE);
		return FALSE;
	}
	return TRUE;
}

设置 EasyX 绘图窗口至桌面壁纸函数（把自绘图窗口变成第三层 Progman 窗口的子窗口）：

	HWND hProgman = FindWindow(L"Progman", 0);				// 找到 第三层 Progman PM 窗口类
	HWND hFfplay = FindWindow(L"EasyXWnd", 0);				// 找到 EasyX 程序 的窗口类窗口
	// HWND hFfplay = GetHWnd(); 不设置成窗口类也行，这个只针对单独程序，EasyXWnd 是针对所有的 EasyX 程序
	SetParent(hFfplay, hProgman);							// 设置 EasyX 程序绘图窗口至桌面

2.整合封装函数

将上述各函数整合封装起来，方便使用，我定义了一个函数：

/* 设置 EASYX 绘图库程序到第三层 Progman 桌面成为时实动态壁纸函数 */
void EasyX_Desktop();

EasyX_Desktop 函数封装内容：

void EasyX_Desktop()
{
	HWND hProgman = FindWindow(L"Progman", 0);				// 找到第三层 PM 窗口
	SendMessageTimeout(hProgman, 0x52C, 0, 0, 0, 100, 0);	// 给它发特殊消息，变成三个桌面窗口
	// HWND hFfplay = FindWindow(L"EasyXWnd", 0);			// 找到 EasyX 窗口类，所有的 EasyX 程序的类
	HWND hFfplay = GetHWnd();								// 本代码程序单独的类或者句柄，不会影响其他的 EasyX 程序
	SetParent(hFfplay, hProgman);							// 将 EasyX 绘图窗口设置为 第三层 Progman 的子窗口，达到动态桌面壁纸目的

	EnumWindows(EnumWindowsProc, 0);						// 隐藏第二层的壁纸
}

设置桌面时实动态壁纸，简单代码模板示例：

int main()
{
	// 合成初始化精简版
	iniwindows(0, 0, 0, 0, RGB(45, 65, 152), L"EASYX 桌面壁纸");
	// 设置本程序窗口，变成时实桌面动态壁纸函数
	EasyX_Desktop();
	// 满屏都是彩色小字母（基于官方代码改的全屏化）
	char_srand();
	// 暂缓
	getmessage(EX_CHAR);
	// 关闭绘图库
	closegraph();
	// 返回
	return 0;
}

3.注意事项

如果 SetParent 函数，设置句柄为窗口类：EasyXWnd。那么所有在运行中的 EasyX 绘图库程序，将全部会被强制设置成桌面子窗口（嵌入桌面成壁纸）。
正常情况下，当程序成功设置为桌面动态时实壁纸时。该程序标题栏会强制变成 XP 系统上的古老样式。很难看，所以得去掉标题栏（包括：最小化、最大化、关闭等按钮）。
某些电脑系统运行该程序，程序设为桌面壁纸并不会立马生效，可能需要重启，或者需要管理员权限。重启电脑后，再次运行，程序设为桌面壁纸程序，则会生效。
在某些系统上。WIN10 系统会放大程序 125 % 的效果，所以桌面壁纸程序会出现不占满屏窗口。需要使用特殊代码还原，本文章代码中有示例。
设置成桌面后，按 ESC 键退出 EasyX 时实桌面动态壁纸。
WIn7 系统可能不支持（没测试过，理论支持），WIN11 系统的电脑也支持（测试过），WIN10 部分高版本系统，可能存在桌面图标消失等问题。原因是单桌面窗口，0x52C 消息没有让单桌面窗口分裂成三层窗口，或者第三层窗口被其他的软件占用。
查看桌面窗口的层，外部获取窗口进程 ID 句柄，线程进程，或者查看 0x52C 消息是否生效。打开 VC 自带的宝藏软件 Spy++ 即可（在菜单栏的工具里）。
