ciao a tutti, ho un problema ke non riesco propio a risolvere..mi sn anke dato da fare cercando in google ma ho trovato 10000 versioni diverse nn facilmente interpretabili,vi espongo il mio problema:
io devo semplicemente modificare un valore nel registro di sistema,ho già usato la funz. cerca,del forum e ho trovato questo:
-----------------------------------------------------------------------------------
Private 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
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As _
Long
Private 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
Const KEY_WRITE = &H20006 '((STANDARD_RIGHTS_WRITE Or KEY_SET_VALUE Or
' KEY_CREATE_SUB_KEY) And (Not SYNCHRONIZE))
Const REG_SZ = 1
Const REG_BINARY = 3
Const REG_DWORD = 4
' Write or Create a Registry value
' returns True if successful
'
' Use KeyName = "" for the default value
'
' Value can be an integer value (REG_DWORD), a string (REG_SZ)
' or an array of binary (REG_BINARY). Raises an error otherwise.
Function SetRegistryValue(ByVal hKey As Long, ByVal KeyName As String, _
ByVal ValueName As String, value As Variant) As Boolean
Dim handle As Long
Dim lngValue As Long
Dim strValue As String
Dim binValue() As Byte
Dim length As Long
Dim retVal As Long
' Open the key, exit if not found
If RegOpenKeyEx(hKey, KeyName, 0, KEY_WRITE, handle) Then
Exit Function
End If
' three cases, according to the data type in Value
Select Case VarType(value)
Case vbInteger, vbLong
lngValue = value
retVal = RegSetValueEx(handle, ValueName, 0, REG_DWORD, lngValue, 4)
Case vbString
strValue = value
retVal = RegSetValueEx(handle, ValueName, 0, REG_SZ, ByVal strValue, _
Len(strValue))
Case vbArray + vbByte
binValue = value
length = UBound(binValue) - LBound(binValue) + 1
retVal = RegSetValueEx(handle, ValueName, 0, REG_BINARY, _
binValue(LBound(binValue)), length)
Case Else
RegCloseKey handle
Err.Raise 1001, , "Unsupported value type"
End Select
' Close the key and signal success
RegCloseKey handle
' signal success if the value was written correctly
SetRegistryValue = (retVal = 0)
End Function

nel senso vi chiederei se potete farmi un esempio pratico,minimo di modifica di un qualsiasi valore. grassie
