win32 最小化工具

本文是仿照Trayconizer软件制作。

本文的最小化工具是能够随意控制一个程序并使之最小化，恢复的软件。如在命令行中运行：

Trayconizer.exe C;\windows\notepad.exe; 

将会打开一个记事本，当点击最小化按钮时，会影藏到后台运行，并在托盘中显示记事本的图标，双击记事本恢复窗口，右键点击弹出“Restore”，“Close”菜单。当记事本关闭后，工具软件也会关闭。工具软件是一直在后台运行的，不会显示窗口。

用到了3个枚举窗口函数。

// 枚举窗口函数BOOL CALLBACK fnAdd(HWND hwnd,LPARAM lParam){ShowWindowAsync(hwnd,SW_MINIMIZE);return TRUE;}// 枚举窗口，将图标从图片删除,Restore菜单BOOL CALLBACK fnDelRestore(HWND hwnd,LPARAM lParam){Shell_NotifyIcon(NIM_DELETE,&g_nid);ShowWindowAsync(hwnd,SW_SHOW);ShowWindowAsync(hwnd,SW_RESTORE);SetForegroundWindow(hwnd);return TRUE;}// 枚举窗口函数,将图标从托盘删除，Close菜单BOOL CALLBACK fnDelClose(HWND hwnd,LPARAM lParam){Shell_NotifyIcon(NIM_DELETE,&g_nid);PostMessage(hwnd,WM_CLOSE,0,0);return TRUE;}

使用钩子来截取应用程序的最小化消息。

// 窗口最小化处理函数void CALLBACK MinProc(HWINEVENTHOOK hWinEventHook,DWORD dwEvent,HWND hwnd,LONG idObject,LONG idChild,DWORD dwEventThread,DWORD dwMsEventTime){#ifdef _DEBUG_WCHAR pwchMsg[128] = { 0 };wsprintf(pwchMsg,_T("%x %x\n"),dwEvent,dwEventThread);WriteConsole(g_hOutput,pwchMsg,wcslen(pwchMsg),NULL,NULL);#endifif(dwEvent == EVENT_SYSTEM_MINIMIZESTART) // 最小化{g_nid.cbSize = sizeof(NOTIFYICONDATA);g_nid.uID = MY_TRAY_ICON_ID;g_nid.uFlags = NIF_ICON | NIF_MESSAGE | NIF_TIP;g_nid.hWnd = g_hWnd;g_nid.uCallbackMessage = WM_MYMSG;wcscpy_s(g_nid.szTip,g_pwchCmdLine);HICON hIcon = (HICON)SendMessage(hwnd,WM_GETICON,ICON_SMALL,0);if(NULL == hIcon){hIcon = (HICON)SendMessage(hwnd,WM_GETICON,ICON_SMALL2,0);if(hIcon == NULL){hIcon = (HICON)SendMessage(hwnd,WM_GETICON,ICON_BIG,0);if(hIcon == NULL){hIcon = (HICON)GetClassLong(hwnd,GCL_HICON);if(hIcon == NULL){SHFILEINFO stFileInfo;::SHGetFileInfo(g_pwchCmdLine,0,&stFileInfo,sizeof(stFileInfo),SHGFI_ICON);hIcon = stFileInfo.hIcon;if(NULL==hIcon)hIcon = LoadIcon(g_hInst,MAKEINTRESOURCE(IDI_TRAYCONIZER));}}}}g_nid.hIcon = hIcon;Shell_NotifyIcon(NIM_ADD,&g_nid);ShowWindow(hwnd,SW_HIDE);}/*else if(dwEvent == EVENT_SYSTEM_MINIMIZEEND){EnumThreadWindows(g_dwTrayPid,fnDelRestore,0);}else if(dwEvent == EVENT_OBJECT_DESTROY) // 关闭{SendMessage(g_hWnd,WM_CLOSE,0,0);}*/}

使用线程监视应用进程是否已经关闭。

// 等待进程关闭，然后结束进程DWORD CALLBACK WaitForClose(LPVOID lpParam){HANDLE hProc = OpenProcess(PROCESS_ALL_ACCESS,FALSE,g_dwTrayPid);WaitForSingleObject(hProc,INFINITE);SendMessage(g_hWnd,WM_CLOSE,0,0);return 0;}
