如何显示桌面？

[pswmetoo]

如题，
快速启动栏目里一般有一个显示桌面的图标，如何才能编程序达成这种效果？

void MinimizeAll()
{
// Simulate a key press
keybd_event( VK_LWIN, // or 0x5B
0x45,
KEYEVENTF_EXTENDEDKEY | 0,
0 );

keybd_event( VK_M, // or 0x5B
0x45,
KEYEVENTF_EXTENDEDKEY | 0,
0 );

keybd_event( VK_M,
0x45,
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
0);

// Simulate a key release
keybd_event( VK_LWIN,
0x45,
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
0);
}

模拟最小化屏幕快捷键Window+D

keybd_event(VK_LWIN,0,0,0);
keybd_event('D',0,0,0);
keybd_event(VK_LWIN,0,KEYEVENTF_KEYUP,0);
keybd_event('D',0,KEYEVENTF_KEYUP,0);


#include <windows.h>
#include <shldisp.h>

int main ()
{
CoInitialize (0);
IShellDispatch4 *pdisp = NULL;
CoCreateInstance (CLSID_Shell, NULL, CLSCTX_ALL, __uuidof (IShellDispatch4), (void **)&pdisp);
pdisp->ToggleDesktop (); // 这句是用来切换桌面的
pdisp->Release ();
CoUninitialize ();
};

最简单的就是用shellexecute调用那个程序好了，：）
