c語言如何打開桌面？

虛擬一個桌面，然后在虛擬桌面啟動explorer進程，用戶可以用"ALT+Q"來切換現有桌面與這個虛擬桌面，用戶需要運行什么軟件，自己在虛擬桌面打開就是了。原理很簡單，實現同樣也很簡單，下面是代碼：

#include

HINSTANCE hInst; //當前實例

TCHAR szAppName[] = TEXT ("VirtualDesk") ; //程序名稱

HWND hwnd ; //主窗體句柄

HDESK hVirtualDesk; //虛擬桌面句柄

HDESK hCurrent; //當前桌面句柄

PROCESS_INFORMATION piExplor; //Explorer進程的PROCESS_INFORMATION結構

LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM);

//每次運行首先檢測注冊表相關項，如果未發現，則設置開機自動運行

void SetStartup(HINSTANCE hInst)

{

HKEY hKey;

DWORD DataType = REG_SZ;

PCSTR data_run = "Software\Microsoft\Windows\CurrentVersion\Run";

long ret = RegOpenKeyEx(HKEY_LOCAL_MACHINE,data_run,0,KEY_ALL_ACCESS,&hKey);

if(ret != ERROR_SUCCESS)

{

MessageBox(NULL,"無法打開注冊表鍵","Error",0);

return;

}

CString ProcessName;

int len = GetModuleFileName(hInst,ProcessName.GetBuffer(256),256);

if(len == 0)

{

MessageBox(NULL,"無法獲取進程的當前目錄","Error",0);

return;

}

ProcessName.ReleaseBuffer(len);

DWORD direcLen = ProcessName.GetLength() + 1;

LPBYTE direc = new BYTE[direcLen];
