salut
moi la fonction regqueryvalue a jamais marché alors j'utilise ca:

dans un module:
Public Function getstring(Hkey As Long, strPath As String, strValue As String)

Dim keyhand As Long
Dim datatype As Long
Dim lResult As Long
Dim strBuf As String
Dim lDataBufSize As Long
Dim intZeroPos As Integer
r = RegOpenKey(Hkey, strPath, keyhand)
lResult = RegQueryValueEx(keyhand, strValue, 0&, lValueType, ByVal 0&, lDataBufSize)
If lValueType = REG_SZ Then
    strBuf = String(lDataBufSize, " ")
    lResult = RegQueryValueEx(keyhand, strValue, 0&, 0&, ByVal strBuf, lDataBufSize)
    If lResult = ERROR_SUCCESS Then
        intZeroPos = InStr(strBuf, Chr$(0))
        If intZeroPos > 0 Then
            getstring = Left$(strBuf, intZeroPos - 1)
        Else
            getstring = strBuf
        End If
    End If
End If
End Function

Function getdword(ByVal Hkey As Long, ByVal strPath As String, ByVal strValueName As String) As Long
Dim lResult As Long
Dim lValueType As Long
Dim lBuf As Long
Dim lDataBufSize As Long
Dim r As Long
Dim keyhand As Long

r = RegOpenKey(Hkey, strPath, keyhand)

 ' Get length/data type
lDataBufSize = 4
    
lResult = RegQueryValueEx(keyhand, strValueName, 0&, lValueType, lBuf, lDataBufSize)

If lResult = ERROR_SUCCESS Then
    If lValueType = REG_DWORD Then
        getdword = lBuf
    End If
'Else
'    Call errlog("GetDWORD-" & strPath, False)
End If

r = RegCloseKey(keyhand)
    
End Function

getstring c'est pour récup une valeur string
getdword c poour recup une valeur numérique

dans ta procédure:

Private Sub cmdGetDWord_Click()
Dim lngDword As String

lngDword = getdword(HKEY_CURRENT_USER, "Software\VBW\Registry", "Dword")
MsgBox lngDword
End Sub

Private Sub cmdGetString_Click()
Dim strString As String

strString = getstring(HKEY_CURRENT_USER, "Software\VBW\Registry", "String")
MsgBox strString
End Sub

ok?
