要通过注册表操作来进行!注册表RUN下写入键值可以达到这个效果! 比如你按下一个按钮来实现开机自启动! Private Sub command1_Click() CreateKey "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run" SetStringValue "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run", "这里写键值的名称随你自定义的", "这里写你程序的路径" '开机启动自己 end sub 然后你添加个模块,里面写(我写的是通用的模块可以进行注册表的各项操作便于你学习就都写出来了,有问题可以百度留言或Q340231101 ): Type FILETIME lLowDateTime As Long lHighDateTime As Long End Type Declare Function RegOpenKeyEx Lib "advapi32.dll" Alias "RegOpenKeyExA" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, ByVal samDesired As Long, phkResult As Long) As Long Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long Declare Function RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal hKey As Long, ByVal lpSubKey As String) As Long Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, ByVal lpData As String, lpcbData As Long) As Long Declare Function RegQueryValueExA Lib "advapi32.dll" (ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, ByRef lpData As Long, lpcbData As Long) As Long Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, ByVal lpData As String, ByVal cbData As Long) As Long Declare Function RegSetValueExA Lib "advapi32.dll" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, ByRef lpData As Long, ByVal cbData As Long) As Long Declare Function RegSetValueExB Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, ByRef lpData As Byte, ByVal cbData As Long) As Long Const ERROR_SUCCESS = 0& Const ERROR_BADDB = 1009& Const ERROR_BADKEY = 1010& Const ERROR_CANTOPEN = 1011& Const ERROR_CANTREAD = 1012& Const ERROR_CANTWRITE = 1013& Const ERROR_OUTOFMEMORY = 14& Const ERROR_INVALID_PARAMETER = 87& Const ERROR_ACCESS_DENIED = 5& Const ERROR_NO_MORE_ITEMS = 259& Const ERROR_MORE_DATA = 234& Const REG_NONE = 0& Const REG_SZ = 1& Const REG_EXPAND_SZ = 2& Const REG_BINARY = 3& Const REG_DWORD = 4& Const REG_DWORD_LITTLE_ENDIAN = 4& Const REG_DWORD_BIG_ENDIAN = 5& Const REG_LINK = 6& Const REG_MULTI_SZ = 7& Const REG_RESOURCE_LIST = 8& Const REG_FULL_RESOURCE_DESCRIPTOR = 9& Const REG_RESOURCE_REQUIREMENTS_LIST = 10& Const KEY_QUERY_VALUE = &H1& Const KEY_SET_VALUE = &H2& Const KEY_CREATE_SUB_KEY = &H4& Const KEY_ENUMERATE_SUB_KEYS = &H8& Const KEY_NOTIFY = &H10& Const KEY_CREATE_LINK = &H20& Const READ_CONTROL = &H20000 Const WRITE_DAC = &H40000 Const WRITE_OWNER = &H80000 Const SYNCHRONIZE = &H100000 Const STANDARD_RIGHTS_REQUIRED = &HF0000 Const STANDARD_RIGHTS_READ = READ_CONTROL Const STANDARD_RIGHTS_WRITE = READ_CONTROL Const STANDARD_RIGHTS_EXECUTE = READ_CONTROL Const KEY_READ = STANDARD_RIGHTS_READ Or KEY_QUERY_VALUE Or KEY_ENUMERATE_SUB_KEYS Or KEY_NOTIFY Const KEY_WRITE = STANDARD_RIGHTS_WRITE Or KEY_SET_VALUE Or KEY_CREATE_SUB_KEY Const KEY_EXECUTE = KEY_READ Dim hKey As Long, MainKeyHandle As Long Dim rtn As Long, lBuffer As Long, sBuffer As String Dim lBufferSize As Long Dim lDataSize As Long Dim ByteArray() As Byte 'This constant determins wether or not to display error messages to the 'user.
