第一种方法:
注释：注释:在Visual Basic 5.0,
注释：声明Vb5stkit.dll.Visual Basic 4.0 中声明Stkit432.dll
注释：VB6中是: VB6STKIT.DLL

Private Declare Function fCreateShellLink _
Lib "STKIT432.DLL" (ByVal lpstrFolderName As String, _
ByVal lpstrLinkName As String, ByVal lpstrLinkPath As _
String, ByVal lpstrLinkArgs As String) As Long

Private Sub Form_Load()
    fCreateShellLink("C:.........StartUp", _
    "MyProgram", "c:myprog.exe", "")

End Sub

第二种方法:

Public Const HKEY_CURRENT_USER = &H80000001
Public Const HKEY_LOCAL_MACHINE = &H80000002
Public Const HKEY_USERS = &H80000003
Public Const HKEY_PERFORMANCE_DATA = &H80000004

            If lResult = ERROR_SUCCESS Then
                RegQueryStringValue = StripTerminator(strBuf)
            End If
        End If
    End If
    
End Function

Public Function GetString(hkey As Long, strpath As String, strvalue As String)

    Dim keyhand&
    Dim datatype&

    Dim intZeroPos As Integer

    intZeroPos = InStr(strString, Chr$(0))
    If intZeroPos > 0 Then
        StripTerminator = Left$(strString, intZeroPos - 1)
    Else
        StripTerminator = strString
    End If
End Function

Public Sub SaveString(hkey As Long, strpath As String, strvalue As String, strdata As String)

    Dim keyhand&
    r = RegCreateKey(hkey, strpath, keyhand&)
    r = RegSetValueEx(keyhand&, strvalue, 0, REG_SZ, ByVal strdata, Len(strdata))
    r = RegCloseKey(keyhand&)

End Sub

注释：Into the form
Private Sub Command1_Click()

    注释：保存一个键值到注册表中
     SaveString HKEY_LOCAL_MACHINE, "SoftwareMicrosoftWindowsCurrentVersionRun", "MyApp", "C:MyApp.exe"
