[C++知识库]C++最小化所有窗口

在某些情况下，模拟 win+D 或者 win+M 键输入或者模拟鼠标点击右下角，去最小化所有窗口并不适用。所以利用 WINAPI 直接去实现这个功能。
上代码 C++.

#include<windows.h>
#include<iostream>
#include<string>

using namespace std;

int main(int argc, const char* argv[]) {

	char szTitle[MAX_PATH] = { 0 };
	char szClass[MAX_PATH] = { 0 };
	int nMaxCount = MAX_PATH;

	LPSTR lpClassName = szClass;
	LPSTR lpWindowName = szTitle;

	while (true) {
		HWND hwnd = GetForegroundWindow();//最前端的窗口 
		
		GetWindowTextA(hwnd, lpWindowName, nMaxCount);
		GetClassNameA(hwnd, lpClassName, nMaxCount);
		cout << "HWND:" << hwnd << "    CLASS NAME: " << lpClassName << "	WINDOWS NAME: " << lpWindowName   << endl;
		std::string str = (std::string)lpClassName;

		if (str.find("TrayWnd") != std::string::npos) {
			std::cout << "HWND: " << hwnd << "		--> Desktop Window" << std::endl;
			break;
		}
		
		PostMessage(hwnd, WM_SYSCOMMAND, SC_MINIMIZE, 0);
		Sleep(100);
	}
	Sleep(200);
}
