| Como podria manipular el registro de windows para añadir una clave en HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run]?
Es para que el programa se ejecute siempre al iniciar windows. Gracias | |

En un modulo pegar este código tal y como está: ' Este modulo es la forma basica de usar el registro ' de Windows, pero se puede implementar para: ' ' - Obtener valores binarios ' - Obtener un valor si la clave existe '------------------------------------------------------------- ' Formato del Editor del Registro (Regedit) ' ' Mi PC ' +__ HKEY_LOCAL_MACHINE ' +___ Software ' +___ Microsoft / ' +___ Windows | BootCount "3" ' +___ CurrentVersion --| BPC_Region "1" ' | ConfigPath "C:\WINDOWS\Config" ' \ ' ' Clave: HKEY_LOCAL_MACHINE ' Subclave: Software; Microsoft; Windows; CurrentVersion ' Entrada: BootCount; BPC_Region; ConfigPath ' Valor: "3"; "1"; "C:\WINDOWS\Config" Dim Ret As Long 'Valor de retorno para todos procedimientos Const REG_SZ = 1 ' Claves principales de Regedit (Solo lectura) Public Const HKEY_CLASSES_ROOT = &H80000000 Public Const HKEY_CURRENT_USER = &H80000001 Public Const HKEY_LOCAL_MACHINE = &H80000002 Public Const HKEY_USERS = &H80000003 Public Const HKEY_PERFORMANCE_DATA = &H80000004 Public Const HKEY_CURRENT_CONFIG = &H80000005 Public Const HKEY_DYN_DATA = &H80000006 Public Const HKEY1 = &H80000000 Public Const HKEY2 = &H80000001 Public Const HKEY3 = &H80000002 Public Const HKEY4 = &H80000003 Public Const HKEY5 = &H80000004 Public Const HKEY6 = &H80000005 Public Const HKEY7 = &H80000006 'Declaraciones API para acceder al registro 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 RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA" (ByVal hKey As Long, ByVal lpValueName As String) 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, lpData As Any, ByVal cbData 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, lpData As Any, lpcbData As Long) As Long Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long | |

| He puesto parte de un codigo para manipular el registro pero no he visto que salga, asi que lo pongo entero, si se corta, mandame un mail y lo mando. Un saludo.
Copia a partir de esta linea y pega el codigo en un modulo.
