Question

我尝试将窗口应用程序放在系统托盘上，它工作正常。当我尝试修改它并使用控制台应用程序时，它不起作用。我在万维网上搜索过，并找到了一个答案，说明如果你能掌握控制台的话，它会起作用。我是winapi的新人有没有人可以帮助我？到目前为止，这是我的代码。

#define ID_TRAY_APP_ICON    1001
#define ID_TRAY_EXIT        1002
#define WM_SYSICON          (WM_USER + 1)
#define IDI_ICON1                       101

GetConsoleWindow()不是您的窗口，它属于可能比您的控制台应用程序更长的其他进程。在＆lt; = Vista GetConsoleWindow返回一个系统窗口，您甚至无法继承子类，因此无法接收托盘图标消息。

取消注释创建自己窗口的代码，并在调用Shell_NotifyIcon时使用该HWND。

如果您希望您的图标比控制台窗口更长，那么您应该创建一个GUI应用程序。当您需要控制台窗口时，它可以调用AllocConsole。

如何将C ++控制台应用程序放入系统托盘通知？
