mfc设置程序开机自启动

程序初始化中加：

char system[MAX_PATH];

    char pathtofile[MAX_PATH];
    HMODULE GetModH = GetModuleHandle(NULL);
    GetModuleFileName(GetModH,pathtofile,sizeof(pathtofile));
    HKEY hKey;
    RegOpenKeyEx(HKEY_LOCAL_MACHINE,
        "Software\\Microsoft\\Windows\\CurrentVersion\\Run",0,KEY_SET_VALUE,&hKey );
    RegSetValueEx(hKey, "Writing to the Registry Example",
        0,REG_SZ,(const unsigned char*)pathtofile,strlen(pathtofile));
    RegCloseKey(hKey);
