这是一些可能满足您需求的代码。调用RegisterProgram
您的 EXE 自行注册,以便在用户登录时自动启动。此函数调用GetModuleFileName
然后调用另一个辅助函数,该函数调用该函数RegisterMyProgramForStartup
将写入注册表。
调用IsMyProgramRegisteredForStartup(L"My_Program")
以检测注册是否确实存在并且是否有效。
一个速记。在实际再次写出之前检查密钥是否存在的性能影响可以忽略不计。您可以盲目地调用 RegisterProgram,如果它已经存在,它将覆盖密钥。检测注册是否存在对于初始化启用或禁用自动启动的 UI 复选框很有用。(你是在给你的用户一个选择,对吧?因为我讨厌那些自动安装并自动运行而不给我选择的应用程序。)
