23 de Septiembre del 2003
Hola que tal, mi problema es que quiero que un pequeño programa .exe que hice en VB 6.0 modifique el registro de Windows de tal manera que la proxima vez que windows se carge tambien se cargue automaticamente mi programa, ocea que no haya nesecidad de volverle a hacer doble Clic. Nesecitaria los codigos y todo lo demas para hacer que esto sea posible.
Agradeceria a la persona que me pudiera brindar esta informacion. Porfavor. gracias.....

Necesitarás usar la API.

Allí encontrarás todos lo métodos y declaraciones necasarias con ejemplos para lo que necesitas.

Hola.
No te serviria con ponerlo, o acceso directo, en la carpeta Inicio, todos los programas de esta carpeta se inician automatiamente al iniciar w.

La parte de código que te he dicho que iba en un módulo, es mejor que la metas en un módulo de clase (en este ejemplo se llama clsRegistro)

Y luego, lo primero que tiene que hacer tu aplicación nada más ejecutarse es algo así:

Dim ObjReaderRegistro As clsRegistro
Dim lRetVal As Long 'result of the API functions
Dim hKey As Long 'handle of opened key
Dim vValue As Variant 'setting of queried value

Set ObjReaderRegistro = New clsRegistro

If RegOpenKeyEx(HKEY_LOCAL_MACHINE, "SOFTWAREMicrosoftOffice9.0AccessJet4.0Engines", 0, KEY_QUERY_VALUE, hKey) = 0 Then
lRetVal = ObjReaderRegistro.QueryValueEx(hKey, "SystemDB", vValue)
RegCloseKey (hKey)
' Aquí haces un show de tu formulario principal para continuar con la aplicación
Else
MsgBox "La aplicación no puede ejecutarse en ordenadores sin Microsoft Office 2000 instalado", vbCritical, "Acción denegada"
End

End If

Set ObjReaderRegistro = Nothing
